Today (July 11) we got our last, best and clearest look at a quartet of perplexing dark spots on Pluto’s far side from NASA’s New Horizons spacecraft – now just two days and two million miles (4 million km) out from history’s first ever up close flyby of the Pluto system on Tuesday, July 14.

The four puzzling spots (see above) are located on the hemisphere of Pluto which always faces its largest moon, Charon, and have captivated the scientists and public alike. Pluto and Charon are gravitationally locked with an orbital period of 6.4 days.

Over only the past few days, we are finally witnessing an amazing assortment of geological wonders emerge into focus from these never before seen worlds – as promised by the New Horizons team over a decade ago.

Be sure to take a good hard look at the image, because these spots and Pluto’s Charon-facing hemisphere will not be visible to New Horizons cameras and spectrometers during the historic July 14 encounter as the spacecraft whizzes by the binary worlds at speeds of some 30,800 miles per hour (more than 48,600 kilometers per hour) for their first up close reconnaissance.

And it’s likely to be many decades before the next visitor from Earth arrives at the frigid worlds at the far flung reaches of our solar system for a longer look, hopefully from orbit.

“The [July 11] image is the last, best look that anyone will have of Pluto’s far side for decades to come,” said New Horizons principal investigator Alan Stern of the Southwest Research Institute, Boulder, Colorado, in a statement.

The image of the mysterious spots was taken earlier today (July 11) by New Horizons Long Range Reconnaissance Imager (LORRI) at a distance of 2.5 million miles (4 million kilometers) from Pluto, and just released by NASA. The image resolution is 10 miles per pixel. One week ago it was only 40 miles per pixel.

They were first seen only in very recent LORRI images as Pluto’s disk finally was resolved and are located in a Missouri sized area about 300 miles (480 kilometers) across and above the equatorial region.

But until today they were still rather fuzzy – see image below from July 3! What a difference a few million miles (km) makes!

“The Pluto system is totally unknown territory,” said Dr. John Spencer, New Horizons co-investigator at today’s (July 11) daily live briefing from NASA and the New Horizons team.

“Pluto is like nowhere we’ve even been before. It is unlike anything we’ve visited before.”

Now, with the $700 million NASA planetary probe millions of miles closer to the double planet, the picture resolution has increased dramatically and the team can at least speculate.

Researchers say the quartet of “equally spaced” dark splotches are “suggestive of polygonal shapes” and the “boundaries between the dark and bright terrains are irregular and sharply defined.”

“It’s weird that they’re spaced so regularly,” says New Horizons program scientist Curt Niebur at NASA Headquarters in Washington.

However their nature remains “intriguing” and truly “unknown.”

“We can’t tell whether they’re plateaus or plains, or whether they’re brightness variations on a completely smooth surface,” added Jeff Moore of NASA’s Ames Research Center, Mountain View, California.

“It’s amazing what we are seeing now in the images, showing us things we’ve never seen before,” said Spencer.

“Every day we see things we never knew before. We see these crazy black and white patterns. And we have no idea what these mean.”

Answering these questions and more is what the encounter is all about.

Pluto is just chock full of mysteries, with new ones emerging every day as New Horizons at last homes in on its quarry, and the planet grows from a spot to an enlarging disk with never before seen surface features, three billion miles from Earth after an interplanetary journey of some nine and a half years.

“We see circular things and wonder are those craters? Or are they something else,” Spencer elaborated.

“We saw circular features on Neptune’s moon Triton that are not craters. So we should know in a few days . But right now we are just having an awful lot of fun just speculating. It’s just amazing.”

Until a few days ago, we didn’t know that “the other Red Planet” had a big bright heart and a dark ‘whale-shaped’ feature – see my earlier articles; here and here.

“When we combine images like this of the far side with composition and color data the spacecraft has already acquired but not yet sent to Earth, we expect to be able to read the history of this face of Pluto,” Moore explained.

New Horizons will swoop to within about 12,500 kilometers (nearly 7,750 miles) of Pluto’s surface and about 17,900 miles (28,800 kilometers) from Charon during closest approach at approximately 7:49 a.m. EDT (11:49 UTC) on July 14.

The probe was launched back on Jan. 19, 2006 on a United Launch Alliance Atlas V rocket on a 9 year voyage of over 3.6 billion miles (5.7 billion km).

Pluto is the last of the nine classical planets to be explored up close and completes the initial the initial reconnaissance of the solar system nearly six decades after the dawn of the space age. It represents a whole new class of objects.

“Pluto is a member of a whole new family of objects,” said Jim Green, director of Planetary Science, NASA Headquarters, Washington, in today’s live Pluto update.

“We call that the Kuiper Belt. And it is the outer solar system.”

New Horizons is equipped with a suite of seven science instruments gathering data during the approach and encounter phases with the Pluto system.

NASA Names Four Astronauts for First Boeing, SpaceX U.S. Commercial Spaceflights

NASA has selected experienced astronauts Robert Behnken, Eric Boe, Douglas Hurley and Sunita Williams to work closely with The Boeing Company and SpaceX to develop their crew transportation systems and provide crew transportation services to and from the International Space Station. Credits: NASA

NASA today (July 9) named the first four astronauts who will fly on the first U.S. commercial spaceflights in private crew transportation vehicles being built by Boeing and SpaceX – marking a major milestone towards restoring American human launches to U.S. soil as soon as mid-2017, if all goes well.

The four astronauts chosen are all veterans of flights on NASA’s Space Shuttles and to the International Space Station (ISS); Robert Behnken, Eric Boe, Douglas Hurley and Sunita Williams. They now form the core of NASA’s commercial crew astronaut corps eligible for the maiden test flights on board the Boeing CST-100 and Crew Dragon astronaut capsules.

Behnken, Boe and Hurley have each launched on two shuttle missions and Williams is a veteran of two long-duration flights aboard the ISS after launching on both the shuttle and Soyuz. All four served as military test pilots prior to being selected as NASA astronauts.

The experienced quartet of space flyers will work closely with Boeing and SpaceX as they begin training and prepare to launch aboard the first ever commercial ‘space taxi’ ferry flight missions to the ISS and back – that will also end our sole source reliance on the Russian Soyuz capsule for crewed missions to low-Earth orbit and further serve to open up space exploration and transportation services to the private sector.

Boeing and SpaceX were awarded contracts by NASA Administrator Charles Bolden in September 2014 worth $6.8 Billion to complete the development and manufacture of the privately developed CST-100 and Crew Dragon astronaut transporters under the agency’s Commercial Crew Transportation Capability (CCtCap) program and NASA’s Launch America initiative.

“I am pleased to announce four American space pioneers have been selected to be the first astronauts to train to fly to space on commercial crew vehicles, all part of our ambitious plan to return space launches to U.S. soil, create good-paying American jobs and advance our goal of sending humans farther into the solar system than ever before,” said NASA Administrator Charles Bolden, in a statement.

“These distinguished, veteran astronauts are blazing a new trail — a trail that will one day land them in the history books and Americans on the surface of Mars.”

The selection of astronauts for rides with NASA’s Commercial Crew Program (CCP) comes almost exactly four years to the day since the last American manned space launch of Space Shuttle Atlantis on the STS-135 mission to the space station on July 8, 2011 from the Kennedy Space Center in Florida.

Hurley was a member of the STS-135 crew and served as shuttle pilot under NASA’s last shuttle commander, Chris Ferguson, who is now Director of Boeing’s CST-100 commercial crew program. Read my earlier exclusive interviews with Ferguson about the CST-100 – here and here.

Since the retirement of the shuttle orbiters, all American and ISS partner astronauts have been forced to hitch a ride on the Soyuz for flights to the ISS and back, at a current cost of over $70 million per seat.

“Our plans to return launches to American soil make fiscal sense,” Bolden elaborated. “It currently costs $76 million per astronaut to fly on a Russian spacecraft. On an American-owned spacecraft, the average cost will be $58 million per astronaut.

Behnken, Boe, Hurley and Williams are all eager to work with the Boeing and SpaceX teams to “understand their designs and operations as they finalize their Boeing CST-100 and SpaceX Crew Dragon spacecraft and operational strategies in support of their crewed flight tests and certification activities as part of their contracts with NASA.”

Until June 2015, Williams held the record for longest time in space by a woman, accumulating 322 days in orbit. Behnken is currently the chief of the astronaut core and conducted six space walks at the station. Boe has spent over 28 days in space and flew on the final mission of Space Shuttle Discovery in Feb. 2011 on STS-133.

The first commercial crew flights under the CCtCAP contract could take place in 2017 with at least one member of the two person crews being a NASA astronaut – who will be “on board to verify the fully-integrated rocket and spacecraft system can launch, maneuver in orbit, and dock to the space station, as well as validate all systems perform as expected, and land safely,” according to a NASA statement.

The second crew member could be a company test pilot as the details remain to be worked out.

The actual launch date depends on the NASA budget allocation for the Commercial Crew Program approved by the US Congress.

Congress has never approved NASA’s full funding request for the CCP program and has again cut the program significantly in initial votes this year. So the outlook for a 2017 launch is very uncertain.

Were it not for the drastic CCP cuts we would be launching astronauts this year on the space taxis.

“Every dollar we invest in commercial crew is a dollar we invest in ourselves, rather than in the Russian economy,” Bolden emphasizes about the multifaceted benefits of the commercial crew initiative.

Under the CCtCAP contract, NASA recently ordered the agency’s first commercial crew mission from Boeing – as outlined in my story here. SpaceX will receive a similar CCtCAP mission order later this year.

At a later date, NASA will decide whether Boeing or SpaceX will launch the actual first commercial crew test flight mission to low Earth orbit.

“This is a new and exciting era in the history of U.S. human spaceflight,” said Brian Kelly, director of Flight Operations at NASA’s Johnson Space Center in Houston, in a statement.

“These four individuals, like so many at NASA and the Flight Operations Directorate, have dedicated their careers to becoming experts in the field of aeronautics and furthering human space exploration. The selection of these experienced astronauts who are eligible to fly aboard the test flights for the next generation of U.S. spacecraft to the ISS and low-Earth orbit ensures that the crews will be well-prepared and thoroughly trained for their missions.”

Both the CST-100 and Crew Dragon will typically carry a crew of four NASA or NASA-sponsored crew members, along with some 220 pounds of pressurized cargo. Each will also be capable of carrying up to seven crew members depending on how the capsule is configured.

The spacecraft will be capable to remaining docked at the station for up to 210 days and serve as an emergency lifeboat during that time.

The NASA CCtCAP contracts call for a minimum of two and a maximum potential of six missions from each provider.

The station crew will also be enlarged to seven people that will enable a doubling of research time.
The CST-100 will be carried to low Earth orbit atop a man-rated United Launch Alliance Atlas V rocket launching from Cape Canaveral Air Force Station, Florida. It enjoys a 100% success rate.

Boeing will first conduct a pair of unmanned and manned orbital CST-100 test flights earlier in 2017 in April and July, prior to the operational commercial crew rotation mission to confirm that their capsule is ready and able and met all certification milestone requirements set by NASA.

The Crew Dragon will launch atop a SpaceX Falcon 9 rocket. It enjoyed a 100% success rate until last weeks launch on its 19th flight which ended with an explosion two minutes after liftoff from Cape Canaveral on June 28, 2015.

SpaceX conducted a successful Pad Abort Test of the Crew Dragon on May 6, as I reported here. The goal was to test the spacecrafts abort systems that will save astronauts lives in a split second in the case of a launch emergency such as occurred during the June 28 rocket failure in flight that was bound for the ISS with the initial cargo version of the SpaceX Dragon.

SpaceX plans an unmanned orbital test flight of Crew Dragon perhaps by the end of 2016. The crewed orbital test flight would follow sometime in 2017.

Pluto’s ‘Heart’ Revealed as New Horizons Probe Starts Flyby Campaign: 5 Days Out

Story updated[/caption]

Emotions are rising exponentially with the rousing revelation that Pluto has a huge ‘Heart’ as revealed in stunning new imagery received just today (July 8) from NASA’s New Horizons spacecraft – which has also officially started its intensive flyby campaign merely 5 days out from humanity’s history making first encounter with the last unexplored planet in our Solar System on Tuesday, July 14.

Notably, today’s image showing Pluto’s ‘heart-shaped’ surface feature proves that New Horizons is now fully back in business following the nail-biting July 4 weekend anomaly that unexpectedly sent the probe into a protective status known as ‘safe mode’ and simultaneously sent mission engineers and scientists scurrying to their computer screens to resolve the scary issues and recover the probe back to full operation – just in the nick of time.

The intriguing ‘heart’ is the brightest area on Pluto and “may be a region where relatively fresh deposits of frost—perhaps including frozen methane, nitrogen and/or carbon monoxide—form a bright coating,” say mission scientists.

While in ‘safe mode’ all science operations were temporarily halted for nearly three days as the spacecraft inexorably zooms towards mysterious Pluto and its quintet of moons for our first up close reconnaissance of the frigid world and the Kuiper Belt.

Read my earlier story from July 6 here detailing how the science team and NASA resolved the July 4 anomaly and restored New Horizons to normal operations with little time to spare for its one time only flyby of the other ‘Red Planet’.

The close encounter sequence last for 9 days and it will take 16 months to relay back the vast quantity of data to be collected.

The view of Pluto’s ‘Heart’ was taken by the Long Range Reconnaissance Imager (LORRI) when the spacecraft was just under 5 million miles (8 million kilometers) from Pluto, and is the first to be received back on Earth since the anxiety rush caused by the July 4 anomaly.

The heart covers nearly half of Pluto’s now well resolved disk.

Right beside the large heart-shaped bright area, which measures some 1,200 miles (2,000 kilometers) across, is another enigmatic and elongated equatorial surface on the left side informally dubbed ‘the whale.’

Mission scientists say ‘the whale’ is one of the darkest regions visible to New Horizons and it measures some 1,860 miles (3,000 kilometers) in diameter, making it about 50% wider that the ‘heart.’

Above ‘the whale and the heart’ lies Pluto’s polar region that images show is intermediate in brightness.

NASA also released another perspective view of ‘the whale and the heart’ as seen below.

‘The whale and the heart of Pluto.’  This map of Pluto, made from images taken by the LORRI instrument aboard New Horizons, shows a wide array of bright and dark markings of varying sizes and shapes. Perhaps most intriguing is the fact that all of the darkest material on the surface lies along Pluto’s equator.

Be sure to keep this entire area in mind – as if your appetites haven’t been whetted enough already – because “this view is centered roughly on the area that will be seen close-up during New Horizons’ July 14 closest approach,” says NASA.

“The next time we see this part of Pluto at closest approach, a portion of this region will be imaged at about 500 times better resolution than we see today,” said Jeff Moore, Geology, Geophysics and Imaging Team Leader of NASA’s Ames Research Center, in a statement. “It will be incredible!”

With barely 5 days to go until the once-in-a-lifetime opportunity for a fast flyby encounter of the ever intriguing binary planet traveling at the far flung reaches of the solar system, last minute glitches are the last thing anyone needs.

Why? Because there are no second chances as New Horizons barrels towards the Pluto system at approximately 30,000 miles per hour (over 48,000 kilometers per hour), which forms a binary planet with its largest known moon – Charon.

“The New Horizons spacecraft and science payload are now operating flawlessly,” Alan Stern, New Horizons principal investigator, Southwest Research Institute, Boulder, Colorado, announced at the July 6 post anomaly media briefing.

The nature of Pluto’s features that may appear to resemble craters or volcanoes is not yet known.

“We should be very cautious in interpreting these features,” Stern told Universe Today.

New Horizons will swoop to within about 12,500 kilometers (nearly 7,750 miles) of Pluto’s surface and about 17,900 miles (28,800 kilometers) from Charon during closest approach at approximately 7:49 a.m. EDT (11:49 UTC) on July 14.

TThe probe was launched back on Jan. 19, 2006 on a United Launch Alliance Atlas V rocket on a 9 year voyage of over 3.6 billion miles (5.7 billion km).

“We are on our way to Pluto!” exclaimed Jim Green, director of Planetary Science, NASA Headquarters, Washington, at the July 6 news media briefing. “It’s really a historic time, fraught with many decisions and challenges on the way to the July 14 Pluto system encounter.”

“With Pluto in our sights, we’re going for the gold.”

Falcon 9 Rocket Failure a Huge Blow to SpaceX: Musk

In his first public comments since the surprise disintegration of the commercial SpaceX Falcon 9 rocket some two minutes after last week’s liftoff on June 28, SpaceX CEO Elon Musk said today (July 7) that the launch failure was a “huge blow” to his company and the cause remains elusive and is under intense investigation.

“The accident was a huge blow to SpaceX,” Musk told the opening session of the International Space Station Research & Development Conference being held in Boston, Mass, during an on-stage conversation with NASA’s International Space Station manager Mike Suffredini.

The private SpaceX Falcon 9 booster broke up just minutes after a picture perfect blastoff from Cape Canaveral on a crucial logistics flight for NASA, carrying a SpaceX Dragon cargo freighter that was headed to the International Space Station (ISS).

Dragon was chock full of over two tons of research experiments and much needed supplies and gear for the multinational crews serving aboard.

“There’s still no clear theory that fits with all the data,” Musk said. “We take these missions incredibly seriously.”

The cargo ships function as a railroad to space and the lifeline to keep the station continuously crewed and functioning. Without periodic resupply by visiting vehicles the ISS cannot operate.

The SpaceX Falcon 9 and Dragon were destroyed just over two minutes after a stunning liftoff from Space Launch Complex 40 at Cape Canaveral Air Force Station in sunny Florida at 10:21 a.m. EDT.

The upper stage of the rocket suddenly exploded due to an as yet unexplained anomaly as the nine first stage Merlin 1D engines kept firing. Moments later it vaporized into a grayish cloud at supersonic speed, raining debris down into the Atlantic Ocean.

Although the second stage appears to be the culprit in the disaster, Musk said that there is still not a coherent cause and explanation of the data and was hard to interpret.

“Whatever happened is clearly not a sort of simple, straightforward thing,” he explained. “In this case, the data does seem to be quite difficult to interpret.”

“So we want to spend as much time as possible just reviewing the data. No clear theory fits all the data.”

The Falcon 9 was transmitting data on over 3,000 channels of flight data streams.

Virtually since the moment of the mishap approximately 139 seconds after the otherwise successful launch, SpaceX engineers have been pouring over the data to try and determine the root cause of the accident.

“Everyone that can engage in the investigation at SpaceX is very, very focused on that,”Musk elaborated. “We want to spend as much time as possible just reviewing the data.”

From the beginning Musk indicated that there was some type of over pressure event in the upper stage liquid oxygen tank and he elaborated a bit at the conference.

“At this point, the only thing that’s really clear was there was some kind of over-pressure event in the upper stage liquid oxygen tank, but the exact cause and sequence of events, there’s still no clear theory that fits with all the data.”

“So we have to determine if some of the data is a measurement error of some kind, or if there’s actually a theory that matches what appear to be conflicting data points.”

SpaceX is conducting an intense and thorough investigation with the active support of various government agencies including the FAA, NASA and the U.S. Air Force.

“The interaction with NASA has been great so far,” Musk said. “The biggest challenge is that there are a lot of inquiries coming in simultaneously, so it’s hard to keep responding to everyone right away.”

The accident investigation is in full swing both at the Cape and SpaceX headquarters in Hawthorne, Ca.

Hans Koenigsmann, SpaceX VP of Mission Assurance, is leading the accident investigation for SpaceX.

“The process for determining the root cause of Sunday’s mishap is complex, and there is no one theory yet that is consistent with the data,” SpaceX spokesman John Taylor told me earlier.

“Our engineering teams are heads down reviewing every available piece of flight data as we work through a thorough fault tree analysis in order to identify root cause.”

The June 28 launch was the 19th overall for the Falcon 9 booster and the first failure in an otherwise hugely successful program by the new space company founded by Musk and headquartered in Hawthorne, CA. Musk’s oft stated goals include radically slashing the cost of access to space to enable much wider participation in the space frontier by entrepreneurs and individuals and foster much greater exploration that will aid human missions to the Red Planet.

SpaceX may have more to say publicly later this week.

“I think we’ll be able to say something more definitive towards the end of the week,” Musk noted.

In the meantime all SpaceX launches are on hold for several months at least.

The SpaceX CRS-7 cargo launch failure was the second of two back to back cargo delivery launch failures run to the space station, including both American and Russian rockets since April, and the third in the past eight months that significantly crimped the stations stockpiles and abruptly impacted upcoming crew rotations and launches throughout the remainder of 2015.

Fortunately, the string of launch failures with the successful launch the Russian Progress 60 cargo freighter on July 3, five days after the SpaceX CRS-7 failure. Progress 60 docked at the ISS on July 5 with three tons of supplies, to the relief of the station partners worldwide.

Despite some hair-raising and unplanned 4th of July fireworks of sorts in deep space which caused NASA’s Pluto bound New Horizons spacecraft to enter “safe mode” due to a computer glitch and temporarily halt all science operations over the weekend, the spacecraft is now fully back on track, “healthy” and working “flawlessly” and set to resume all planned research investigations on Tuesday, July 7, NASA and top mission managers announced at a media briefing held this afternoon, Monday, July 6.

It’s now just exactly one week before the once-in-a-lifetime opportunity for a fast flyby encounter of the ever intriguing binary planet, at the far flung reaches of the solar system. And the great news could not come soon enough given the proximity of the flyby.

“The spacecraft is in excellent health and back in operation. New Horizons is barreling towards the Pluto system,” stated Jim Green, director of Planetary Science, NASA Headquarters, Washington, at the start of today’s news media briefing.

The $700 million mission remains on track to conduct the complex close flyby science sequence in its entirety, as planned over the next week, including the July 14 flyby of Pluto, despite the scary safe mode episode.

“The New Horizons spacecraft and science payload are now operating flawlessly,” Alan Stern, New Horizons principal investigator, Southwest Research Institute, Boulder, Colorado, announced at the media briefing.

NASA unexpectedly lost contact with the New Horizons spacecraft on Saturday, July 4, at about 1:30 p.m. EDT after it suffered a memory related software anomaly and executed a protective operation known as “safe mode.” An anomaly investigation team was formed immediately.

“It’s really a historic time, but also fraught with many decisions and challenges on the way to the July 14 Pluto system encounter,” Green said.

The mission team quickly worked to reestablish contact with the piano shaped spacecraft about 90 minutes after the signal was lost.

“On Saturday we lost contact with the spacecraft. The New Horizons team immediately went into action. Within 90 minutes the signal was reacquired by the team, with the spacecraft in safe mode. They soon found the root cause and corrective actions were immediately taken to get the spacecraft back in business.”

The team worked tirelessly and diligently day and night over the holiday weekend to recover New Horizons back to full operation quickly and in time for the flyby encounter of Pluto on July 14, set for approximately 7:49 a.m. EDT (11:49 UTC) on July 14, said Glen Fountain, New Horizons project manager, Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland.

There are no second chances.

The software glitch occurred a day after new operating software was uploaded to New Horizons last Friday.

The spacecraft was trying to do two things at once on Saturday, compressing science data and writing command sequences while using up too much flash memory, explained Fountain.

“The computer was trying to do these two things at the same time, and the two were more than the processor could handle,” Fountain said.

“So the processor said ‘I’m overloaded.’ Then the spacecraft did exactly what it was supposed to do. It then switched to the backup computer and went into safe mode. At that point, we lost the downlink from the primary computer. We realized quickly what happened and put a recovery plan in place and recovered.”

At this moment New Horizons is about 3 billion miles (4.9 billion km) from Earth and less than 6 million miles (9 million km) away from unmasking the secrets of tantalizing Pluto, Charon, its largest moon with which it forms a double planet system, and its four tiny and recently discovered moons. Charon is half the size of Pluto.

The round trip time for signals traveling at the speed of light is 8.5 hours. So it’s a very long time before commands from Earth can reach the spacecraft and for the team to determine their outcome. So the probe has to be able to operate on its own without direction from Earth during the intense and brief flyby period.

Pluto is the most distant and last unexplored planet in our Solar System, and therefore presents enormous complexities to those bold enough to dare the mightiest things.

“We expect a nominal flyby of Pluto from every indication now,” said Alan Stern, New Horizons principal investigator, Southwest Research Institute, Boulder, Colorado, announced at the media briefing.

“This object is unlike any other that we have observed,” Stern said. “Both Pluto and Charon are already surprising us.”

Less than 1 percent of the planned data was lost in the three days that the science instruments were shut off.

“It’s more important to focus on the later science during the flyby,” Stern elaborated.

“There is zero impact to the primary Group 1 highest-priority science objectives. And a minor impact to Group 2 and Group 3 objectives,” Stern elaborated.

“This is a speed bump in terms of the total return that we expect from this flyby.”

“I’m pleased that our mission team quickly identified the problem and assured the health of the spacecraft,” noted Green. “Now, with Pluto in our sights, we’re on the verge of returning to normal operations and going for the gold.”

The team said this type of software update will not be repeated and a similar type safe mode event should not recur.

Fountain said that during the encounter period, the probe can switch itself to exit safe mode event within about 7 minutes, depending on the situation, and minimize any science data losses.

New Horizons will swoop to within about 12,500 kilometers (nearly 7,800 miles) of Pluto’s surface.

It will zoom past Pluto at speeds of some 30,000 miles per hour (more than 48,000 kilometers per hour).

Today the team also released the best yet images of Pluto that were taken by the Long Range Reconnaissance Imager (LORRI). The trio of images were between July 1 and 3 of 2015, prior to the July 4 anomaly that sent New Horizons into safe mode.

The images show varying and enigmatic surface features on the different hemispheres of Pluto.

They also show the four mysterious dark spots on Pluto that have captured the imagination of the scientists and the world.

Their nature remains unknown at this time.

The probe was launched back in 2006 on a United Launch Alliance Atlas V rocket.

“We are on our way to Pluto!” Green exclaimed.

Russian Progress Supply Freighter Docks at Space Station, Ending String of International Launch Failures

Over three tons of much needed supplies and equipment finally reached the crew living aboard the International Space Station (ISS), when an unmanned and highly anticipated Russian Progress cargo ship successfully docked at the orbiting outpost early this morning, Sunday July 5, at 3:11 a.m. EDT (10:11 MSK, Moscow local time)- to all the partners relief.

This follows two straight international resupply launch failures that significantly crimped the stations stockpiles and abruptly impacted upcoming crew rotations and station launches throughout the remainder of 2015.

Today’s arrival of Russia’s Progress 60 (Progress M-28M) logistics vehicle ended a string of Russian and American resupply mission failures that began some two months ago with the devastating Soyuz rocket launch failure of the prior Progress 59 ship on April 28, and continued with the mid-air explosion of a commercial SpaceX Falcon 9 and unpiloted SpaceX Dragon CRS-7 cargo ship exactly one week ago on June 28.

The Progress 60 was automatically docked at an earth facing port on the Russian “Pirs” docking module on the Russian segment of the ISS – that finally puts the station on the road to recovery with a stockpile of 6100 pounds (2770 kg) of new fuel, food, oxygen, research experiments and gear.

“The operation was carried out in an automated mode,” according to Russian Mission Control near Moscow.

The docking operation was conducted under the guidance of the Russian ISS Expedition 44 commander Gennady Padalka and flight engineer Mikhail Kornienko as well as experts at the Russian Mission Control Center, as the vehicles were soaring about 251 miles (400 km) over the south Pacific, southeast of New Zealand. NASA astronaut Scott Kelly is also aboard, rounding out the current three man crew.

The successful docking came two days after the blastoff of the unmanned Progress 60 cargo freighter atop a Soyuz-U booster from the Baikonur Cosmodrome on July 3. This signifies the restoration of Russia’s critical cargo lifeline to the ISS and was like celebrating Christmas in July.

“Guys, congratulations. your cargo vehicle has arrived,” said Russian flight director Vladimir Solovyev from Russian mission control.

“We congratulate you as well,” cosmonaut Gennady Padalka replied from inside the station’s Russian-built Zvezda command module. “Thanks so much for sending it our way. It feels like Christmas in July.”

The station is totally dependent on a regular train of supply runs from the partner nations on Earth to operate with a crew and conduct research investigations that will aid in sending humans to deep space destinations.

America’s cargo lifeline is currently on hold following the dual launch failures of both US commercial supply trains to low Earth orbit- involving the SpaceX Falcon 9 last week and the catastrophic Orbital ATK Antares/Cygnus Orb-3 mission launch disaster on October 28, 2014 which I saw at NASA Wallops.

The SpaceX Falcon 9 and Dragon exploded barely two minutes after liftoff from Cape Canaveral. The rocket disintegrated in mere moments as I watched from the roof of the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida.

All told, an unprecedented trio of launch failures with three different American and Russian rockets took place over the past eight months.

Progress 60 resupply ship was loaded with over three tons of food, fuel, oxygen, science experiments, water and supplies on a crucial mission for the International Space Station crew to keep them stocked with urgently needed life support provisions and science experiments in the wake of the twin launch failures in April and June.

The ship delivered approximately 1,146 pounds (520 kg) of propellant, 105 pounds (48 kg) of oxygen, 926 pounds (420 kg) of water and 3,071 pounds (1393 kg) pounds of crew supplies, provisions, research equipment, science experiments, student experiments, tools and spare parts and parcels for the crew.

The Progress was stuffed with 100 kg of additional food stocks to make up for the losses suffered from the twin Russian Progress 59 and SpaceX CRS-7 failures.

“As for food, 430 kilos of foodstuffs will be delivered to the ISS or 100 kilos more than the amount delivered by the previous spacecraft,” noted Mission Control.

“The Progress space freighter will deliver more food than usual so that it will suffice for everyone,” Alexander Agureyev, chief of the ISS crew nourishment department at the Institute of Medical and Biological Problems, told the Russian news agency TASS.

Progress 60 is scheduled to remain docked to Pirs for the next four months.

In the wake of the trio of American and Russian launch failures, the crew currently enjoys only about four months of reserves compared to the more desirable six months stockpile in case of launch mishaps.

Progress 60 will extend the station supplies by about a month’s time.

The next cargo ship now slated to launch is the Japanese HTV-5 on August 16.

The SpaceX CRS-7 Dragon was packed with over 4,000 pounds (1987 kg) of research experiments, an EVA spacesuit, water filtration equipment, spare parts, gear, computer equipment, high pressure tanks of oxygen and nitrogen supply gases, food, water and clothing for the astronaut and cosmonaut crews comprising Expeditions 44 and 45.

These included critical materials for the science and research investigations for the first ever one-year crew to serve aboard the ISS – comprising NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko.

The Dragon was also packed with the first of two new International Docking Adapters (IDS’s) required for the new commercial crew space taxis being built by Boeing and SpaceX to dock at the ISS starting in 2017.

The next crewed launch to the station is set for July 22 aboard a Soyuz capsule with with an international trio comprising NASA astronaut Kjell Lindgren, Oleg Kononenko of the Russian Federal Space Agency and Kimiya Yui of the Japan Aerospace Exploration Agency. Their flight was delayed from May 26 after the Progress 59 launch failure to ensure that there are no issues with the Soyuz rocket booster that will boost them to the ISS.

NASA’s two lost Shuttle crews from the searing Challenger and Columbia accidents are now memorialized in the newly opened, permanent and highly emotional “Forever Remembered” tribute display at the Kennedy Space Center Visitor Complex in Florida.

The “Forever Remembered” memorial tribute was officially opened by NASA Administrator Charles Bolden and Kennedy Space Center Director Bob Cabana, both veteran shuttle astronauts, at a very special and moving small private NASA ceremony attended by families of the 14 fallen crew members and invited members of the media including Universe Today on June 27, 2015.

“I believe that it’s important to share this story with everyone, and not just push it aside, or try to hide it,” Cabana said at the ceremony, as tears welled up in everyone present.

The shuttle tribute is located on the ground floor of the Space Shuttle Atlantis pavilion at the Kennedy Space Center Visitor Complex and features shuttle orbiter hardware recovered from both the Challenger STS-51L and Columbia STS-107 accidents, as well as personal crew items from all 14 courageous astronauts who lost their lives – items never before on display for viewing by the public.

The 2000 square foot exhibit features an iconic section of the fuselage recovered from space shuttle Challenger emblazoned with the American flag and the flight deck windows recovered from space shuttle Columbia, that are part of the permanent “Forever Remembered” memorial that opened on June 27, 2015 – see photo above.

It also holds the largest collection of personal items of both flight crews in individual displays about the 14 crew members in a hallway that leads to a plaque with a quote from U.S. President Ronald Reagan.

“The future doesn’t belong to the fainthearted, it belongs to the brave,” said President Ronald Reagan in remarks to the nation in mourning shortly after the explosion of Space Shuttle Challenger on Jan. 28, 1986.

The “Forever Remembered” display was conceived in private by a very small circle spearheaded by Cabana and unknown by outsiders until the day it was formally opened. It completes the display inside the Atlantis pavilion, which commemorates NASA’s three decade long Space Shuttle Program that flew 135 missions from 1981 to 2011 with the reusable delta-winged vehicles that “captivated a generation.”

It is intended to be an emotional experience and “designed to honor the crews, pay tribute to the spacecraft and emphasize the importance of learning from the past” and the tragic consequences. This will enable safer flights in the future and fortify the spirit of never giving up on the exploration of space.

“The tragedies galvanized the agency to learn from these painful events, not only to safely return the shuttle fleet to flight, but to help assure the safety of future explorers,” NASA said in a statement.

Several dozen family members attended the tearful, heartfelt opening ceremony of “Forever Remembered” with very emotional remarks from Cabana and Bolden.

“These crews and these vehicles are part of who we are as an agency, and a nation. They tell the story of our never ending quest to explore, and our undying spirit to never give up,” Cabana stated at the ceremony.

Columbia and Challenger were the nation’s first two orbiters to be built. Columbia launched on the maiden space shuttle flight on April 12, 1981 on what is revered by many as the “boldest test flight in history” with NASA astronauts John Young and Bob Crippen.

“When I look into those windows, I see John Young and Bob Crippen preparing to launch on the boldest test flight in history, the first flight of America’s space shuttle, Columbia,” Cabana added.

“I see a much younger Bob Cabana launching to space on his first command, and I see Rick and Willie and the rest of the 107 crew smiling and experiencing the wonders of space on the final flight of Columbia.”

The idea to create a permanent memorial originated with a team led by Bob Cabana, and approved by Charlie Bolden only after every one of the astronauts families were in complete and unqualified agreement that this tribute display was the right thing to do in memory of their loved ones, tragically lost during the in flight accidents in 1986 and 2003.

“The crews of Challenger and Columbia are forever a part of a story that is ongoing,” Bolden said at the ceremony.

“It is the story of humankind’s evolving journey into space, the unknown, and the outer-reaches of knowledge, discovery and possibility. It is a story of hope.”

The wives of the two shuttle commanders, shared their thoughts on the new exhibit:

“It’s a beautiful remembrance of all the shuttles, with the marvelous display of Atlantis. Nothing compares to it in the world,” said June Scobee Rodgers, whose husband, Dick Scobee, commanded Challenger on STS-51L, in a statement.

“But Challenger and Columbia are not forgotten, and they’re well represented.”

“I knew it would be very emotional to see, but honestly, I didn’t expect to be so impacted by it. I just can’t stop thinking about it. As you walk in, you know you’re in a special place,” Evelyn Husband Thompson said of the memorial. Her husband, Rick, commanded Columbia on STS-107.

Here is a NASA description of both the Columbia and Challenger accidents and crews:

“Temperatures at Kennedy Space Center were just a few degrees above freezing on the morning of Jan. 28, 1986, as Challenger lifted off on its 10th mission, STS-51L. One minute and 13 seconds into the flight, a booster failure caused an explosion that destroyed the vehicle, resulting in the loss of the crew of seven astronauts: Commander Francis Scobee, Pilot Michael J. Smith, Mission Specialists Judith Resnik, Ellison Onizuka and Ronald McNair, and Payload Specialists Gregory Jarvis and Christa McAuliffe, a New Hampshire schoolteacher.”

“Seventeen years later, on Jan. 16, 2003, NASA’s flagship orbiter Columbia thundered into orbit on STS-107, a 16-day science mission. On board were Commander Rick Husband, Pilot Willie McCool, Payload Commander Michael Anderson, Mission Specialists Kalpana Chawla, David Brown and Laurel Clark, and Payload Specialist Ilan Ramon, Israel’s first astronaut. On Feb. 1, 2003, the orbiter broke apart in the skies above east Texas as it re-entered Earth’s atmosphere on the way to a planned landing at Kennedy. Seven more lives were lost.”

Today the fallen astronauts legacy of human spaceflight lives on at NASA with the International Space Station, the development of Commercial Crew manned capsules for low Earth orbit, and the development of the Orion deep space crew exploration vehicle and SLS rocket for NASA’s ambitious plans to send ‘Human to Mars’ in the 2030s.

Read more about both fallen shuttle crews and the Apollo 1 crew who perished in a launch pad accident in January 1967 in my tribute story posted here during NASA’s solemn week of remembrance in January.

The explosion of the SpaceX Falcon 9 rocket some two minutes after launch on June 28, 2015 is a reminder that space flight is never easy or routine. Starting sometime in 2017, astronauts will launch to the ISS in a crew Dragon atop the Falcon 9. It will be equipped with a launch abort system that the shuttles never had, in case of a launch emergency.

I urge everyone to visit this hallowed “Forever Remembered” memorial at the Kennedy Space Center Visitor Complex and remember those who made the ultimate sacrifice to benefit all of us in the quest for new knowledge of the boundless expanse of space leading to new discoveries we cannot fathom today.

A sigh of relief was heard worldwide with today’s (July 3) successful launch to orbit of the unmanned Progress 60 cargo freighter atop a Soyuz-U booster from the Baikonur Cosmodrome, signifying the restoration of Russia’s critical cargo lifeline to the International Space Station (ISS), some two months after the devastating launch failure of the prior Progress 59 spaceship on April 28.

Friday’s triumphant Progress launch also comes just five days after America’s cargo deliveries to the ISS were put on hold following the spectacular failure of a commercial SpaceX Falcon 9 rocket launched from the Florida Space Coast on Sunday, June 28, carrying the unpiloted SpaceX Dragon CRS-7 which broke up in flight.

The Progress 60 resupply ship, also known as Progress M-28M, was loaded with over three tons of food, fuel, oxygen, science experiments, water and supplies on a crucial mission for the International Space Station crew to keep them stocked with urgently needed life support provisions and science experiments in the wake of the twin launch failures in April and June.

The Soyuz-U carrier rocket launched Progress into blue skies at 10:55 a.m. local time in Baikonur (12:55 a.m. EDT) from the Baikonur Cosmodrome in Kazakhstan. The launch was webcast live on NASA TV.

“Everything went by the book,” said NASA commentator Rob Navias during the webcast. “Everything is nominal.”

The International Space Station was flying about 249 miles over northwestern Sudan, near the border with Egypt and Libya, at the moment of liftoff. Note: See an exquisite photo of the Egyptian pyramid photographed from the ISS in my recent story – here.

After successfully separating from the third stage Progress reach its preliminary orbit less than 10 minutes after launch from Baikonur and deployed its solar arrays and navigational antennas as planned.

Live video was received from Progress after achieving orbit showing a beautiful view of the Earth below.

A two day chase of 34 orbits of Earth over the next two days will bring the cargo craft to the vicinity of the station for a planned docking to the Russian segment of the orbiting laboratory at 3:13 a.m. Sunday, July 5.

NASA TV will provide live coverage of the arrival and docking operation to the Pirs Docking Compartment starting at 2:30 a.m. EDT on Sunday, July 5.

NASA astronaut Scott Kelly and Russian cosmonauts Mikhail Kornienko and Gennady Padalka are currently living and working aboard the station as the initial trio of Expedition 44 following the safe departure and landing of the three person Expedition 43 crew in mid June.

Kelly and Kornienko comprise the first ever 1 Year Crew to serve aboard the ISS and are about three months into their stay in space.

In the span of just the past eight months, three launches of unmanned cargo delivery runs to the space station have failed involving both American and Russian rockets.

The cargo ships function as a railroad to space and function as the lifeline to keep the station continuously crewed and functioning. Without periodic resupply by visiting vehicles from the partner nations the ISS cannot continue to operate.

The Orbital Sciences Antares/Cygnus Orb 3 mission exploded in a massive and frightening fireball on October 28, 2014 which I witnessed from the press site from NASA Wallops in Virginia.

The Russian Soyuz/Progress 59 mission failed after the cargo vessel separated from the Soyuz booster rockets third stage and spun wildly out of control on April 28, 2015 and eventually crashed weeks later during an uncontrolled plummet back to Earth over the ocean on May 8. The loss was traced to an abnormal third stage separation event.

Roscosmos, the Russian Federal Space Agency, switched this Progress vehicle to an older version of the Soyuz rocket which had a different third stage configuration that was not involved in the April failure.

Russian officials decided to move up the launch by about a month from its originally planned launch date in August in order to restock the station crew with critically needed supplies as soon as practical.

Following Sundays SpaceX cargo launch failure, the over 6100 pounds of new supplies on Progress are urgently needed more than ever before. Loaded aboard are 1,146 pounds (520 kg) of propellant, 105 pounds (48 kg) of oxygen, 926 pounds (420 kg) of water and 3,071 pounds (1393 kg) pounds of crew supplies, provisions, research equipment, science experiments, tools and spare parts and parcels for the crew.

In the wake of the trio of American and Russian launch failures, the crews current enjoy only about four month of supplies reserves compared to the more desirable six months stockpile in case of launch mishaps.

Progress 60 will extend the station supplies by about a month’s time.

The SpaceX CRS-7 Dragon was loaded with over 4,000 pounds (1987 kg) of research experiments, an EVA spacesuit, water filtration equipment, spare parts, gear, computer equipment, high pressure tanks of oxygen and nitrogen supply gases, food, water and clothing for the astronaut and cosmonaut crews comprising Expeditions 44 and 45.

These included critical materials for the science and research investigations for the first ever one-year crew to serve aboard the ISS – comprising Kelly and Kornienko.

The Dragon was also packed with the first of two new International Docking Adapters (IDS’s) required for the new commercial crew space taxis to dock at the ISS starting in 2017.

The three cargo launch failures so close together are unprecedented in the history of the ISS program over the past two decades.

The next cargo ship now slated to launch is the Japanese HTV-5 on August 16.

Falcon 9 Failure Investigation Focuses on Data not Debris as SpaceX Seeks Root Cause

KENNEDY SPACE CENTER, FL – SpaceX and NASA are diligently working to “identify the root cause” of the June 28 in flight failure of the firms Falcon 9 rocket, as the accident investigation team focuses on “flight data” rather than recovered debris as the best avenue for determining exactly what went wrong, a SpaceX spokesperson told Universe Today.

The SpaceX Falcon 9 booster broke up just minutes after a picture perfect blastoff from a seaside Florida launch pad on a critical mission for NASA bound for the International Space Station (ISS). It was carrying a SpaceX Dragon cargo freighter loaded with research equipment and new hardware to enable crewed spaceships to dock at the orbiting outpost.

The accident investigation team is still seeking the root cause of the launch failure through a complex fault tree analysis.

“The process for determining the root cause of Sunday’s mishap is complex, and there is no one theory yet that is consistent with the data,” said SpaceX spokesman John Taylor.

The accident investigation is in full swing both at the Cape and SpaceX headquarters in Hawthorne, Ca.

“Our engineering teams are heads down reviewing every available piece of flight data as we work through a thorough fault tree analysis in order to identify root cause.”

Hans Koenigsmann, SpaceX VP of Mission Assurance, is leading the accident investigation for SpaceX.

SpaceX is conducting an intense and thorough investigation with the active support of various government agencies including the FAA, NASA and the U.S. Air Force.

The SpaceX Falcon 9 and Dragon were destroyed just over two minutes after a stunning liftoff from Space Launch Complex 40 at Cape Canaveral Air Force Station in sunny Florida at 10:21 a.m. EDT.

The SpaceX CRS-7 cargo resupply mission to the ISS began flawlessly. The nine Merlin 1D engines powering the Falcon 9 rockets first stage were firing nominally at launch to produce about 1.3 million pounds of liftoff thrust for almost their entire duration.

However, approximately 139 seconds into the planned 159 second firing of the first stage engine, the majestic blastoff went awry as the upper stage of the vehicle experienced an as yet unexplained anomaly and suddenly exploded, vaporizing into a grayish cloud at supersonic speed and raining debris down into the Atlantic Ocean.

The Falcon 9 has transmitting data on over 3,000 channels of flight data streams.

But something went wrong apparently with the upper stage said SpaceX CEO Elon Musk.

“There was an overpressure event in the upper stage liquid oxygen tank. Data suggests counterintuitive cause,” tweeted Musk.

But why that happened and the vehicle disintegrated in mere seconds is still a mystery to be resolved through careful fault tree analysis of the data.

“Cause still unknown after several thousand engineering-hours of review. Now parsing data with a hex editor to recover final milliseconds.”

While SpaceX and Coast Guard ships have recovered some debris in the days since the launch mishap, the data streams are expected to be the most useful source of information to the investigation team.

Hex editors are being used to comb through the data.

A hex editor (or binary file editor or byte editor) is a type of computer program that allows for manipulation of the fundamental binary data that constitutes a computer file.

The name ‘hex’ comes from ‘hexadecimal’: a standard numerical format for representing binary data.

Some data was transmitted after the breakup.

The accident investigation teams are currently in the process of recreating the final milliseconds of the flight to give them some additional insights into what may have happened, when and why.

In the meantime all SpaceX launches are on hold for several months at least.

The next Falcon 9 launch scheduled was for NASA’s Jason 3 from Vandenberg Air Dorce Base in California

The next SpaceX cargo Dragon had been scheduled for liftoff in September 2015 on the CRS-8 mission, but is now postponed pending the results of the return to flight investigation.

There are sufficient supplies on board the ISS to keep the crew continuing their mission until at least October 2015.

The SpaceX CRS-7 Dragon was loaded with over 4,000 pounds (1987 kg) of research experiments, an EVA spacesuit, water filtration equipment, spare parts, gear, computer equipment, high pressure tanks of oxygen and nitrogen supply gases, food, water and clothing for the astronaut and cosmonaut crews comprising Expeditions 44 and 45.

The Dragon was also packed with the first of two new International Docking Adapters (IDS’s) required for the new commercial crew space taxis to dock at the ISS starting in 2017.

Another Russian Progress vehicle is set to fly on the next resupply mission from the Baikonur Cosmodrome on Friday, July 3.

KENNEDY SPACE CENTER, FL – The root cause of Sundays (June 28) devastating launch failure of the commercial SpaceX Falcon 9 rocket is “still unknown” says SpaceX CEO and founder Elon Musk, following the loss of the NASA contracted resupply mission carrying crucial gear and research experiments to the crew serving aboard the Earth orbiting International Space Station (ISS).

Meanwhile, search and recovery teams from SpaceX and the Coast Guard are scouring the ocean and beaches along the Florida Space Coast for any signs of potentially dangerous Falcon rocket debris that rained down from the sky into the Atlantic Ocean after the sudden explosion unexpectedly destroyed the vehicle barely two minutes after a sun drenched liftoff from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida at 10:21 a.m. EDT.

All appeared normal as the Falcon 9 booster and Dragon resupply spaceship were streaking skywards through majestically blue Florida skies when catastrophe struck at approximately 148 seconds after blastoff and the rocket exploded violently- utterly destroying the rocket ship and its two ton load of critical supplies heading to the astronauts and cosmonauts living on board the ISS.

The upper stage appeared to break up in flight as the nine first stage Merlin 1D engines were firing as planned and the rocket was arcing over.

But why that happened and the vehicle disintegrated in mere seconds is still a mystery which will take some time to resolve.

“Cause still unknown after several thousand engineering-hours of review. Now parsing data with a hex editor to recover final milliseconds,” tweeted SpaceX CEO Elon Musk.

Although the cause is unknown, Musk also announced that the failure might be related to a problem with the Falcon 9 upper stage. since the first stage engines were still firing as planned.

“There was an overpressure event in the upper stage liquid oxygen tank. Data suggests counterintuitive cause,” tweeted Musk.

The rocket was traveling about 5000 km/h at an altitude of 45 kilometers at the time of the mishap.

“Falcon 9 experienced a problem shortly before first stage shutdown. Will provide more info as soon as we review the data,” tweeted SpaceX CEO Elon Musk soon after the explosion.

The pressurized section of the Dragon was packed with over 4,000 pounds of research experiments, spare parts, gear, high pressure supply gases, food, water and clothing for the astronaut and cosmonaut crews comprising Expeditions 44 and 45 on the ISS.

Sunday’s launch was the 19th launch of the Falcon 9 rocket and the first failure after 18 straight successes.

SpaceX formed a failure investigation board immediately following the launch failure of the SpaceX Commercial Resupply Services 7 (CRS-7) mission bound for the ISS. The FAA and NASA will assist in the investigation.

The launch was the sixth for SpaceX this year, which had been picking up its launch pace dramatically compared to 2014.

It was the third launch failure of a cargo delivery run to the space station in the past half year -including both American and Russian rockets.

The Orbital Sciences Antares/Cygnus Orb 3 mission exploded in a massive an frightening fireball on October 28, 2014 which I witnessed from the press site from NASA Wallops in Virginia.

The Russian Soyuz/Progress 59 mission failed after the cargo vessel separated from the booster rockets third stage and spun wildly out of control in April 2015 and eventually crashed.
