President Obama gave a shout out to NASA Astronaut Scott Kelly and his upcoming 1 year mission to the International Space Station at the 2015 State of the Union address to the US Congress on Tuesday evening, Jan. 20, 2015.
Obama wished Kelly (pictured above in the blue jacket) good luck during his address and told him to send some photos from the ISS via Instagram. Kelly was seated with the First Lady, Michelle Obama, during the speech on Capitol Hill.
The TV cameras focused on Kelly and he was given a standing ovation by the Congress and the President.
Obama also praised Kelly’s flight and the recent Dec. 5, 2014, launch of NASA’s Orion deep space capsule as “part of a re-energized space program that will send American astronauts to Mars.”

Here’s a transcript of President Obama’s words about NASA, Orion, and Scott Kelly’s 1 Year ISS mission:
“Pushing out into the Solar System not just to visit, but to stay. Last month, we launched a new spacecraft as part of a re-energized space program that will send American astronauts to Mars. In two months, to prepare us for those missions, Scott Kelly will begin a year-long stay in space. Good luck, Captain and make sure to Instagram it.”
In late March, Astronaut Scott Kelly will launch to the International Space Station and become the first American to live and work aboard the orbiting laboratory for a year-long mission.
Scott Kelly and Russian Cosmonaut Mikhail Kornienko, both veteran spacefliers, comprise the two members of the 1 Year Mission crew.
Normal ISS stays last for about a six month duration.

No American has ever spent anywhere near a year in space. 4 Russian cosmonauts conducted long duration stays of about a year or more in space aboard the Mir Space Station in the 1980s and 1990s.
Together with Russian cosmonaut Gennady Padalka, Kelly and Kornienko will launch on a Russian Soyuz capsule from the Baikonur Cosmodrome as part of Expedition 44.
Kelly and Kornienko will stay aboard the ISS until March 2016.
They will conduct hundreds of science experiments focusing on at least 7 broad areas of investigation including medical, psychological, and biomedical challenges faced by astronauts during long-duration space flight.

A busy year of 13 space launches by rocket provider United Launch Alliance (ULA) in 2015 begins with a pair of blastoffs for the US Navy and NASA tonight and next week, emanating from both the US East and West Coasts.
The hefty manifest of 13 liftoffs in 2015 comes hot on the heels of ULA’s banner year in 2014 whereby they completed every one of the firm’s 14 planned launches in 2014 with a 100% success rate.
“What ULA has accomplished in 2014, in support of our customers’ missions, is nothing short of remarkable,” said ULA CEO Tory Bruno.
“When you think about every detail – all of the science, all of the planning, all of the resources – that goes into a single launch, it is hard to believe that we successfully did it at a rate of about once a month, sometimes twice.”
ULA’s stable of launchers includes the Delta II, Delta IV and the Atlas V. They are in direct competition with the Falcon 9 rocket from SpaceX founded by billionaire Elon Musk.
And ULA’s 2015 launch calendar begins tonight with a milestone launch for the US Navy that also marks the 200th launch overall of the venerable Atlas-Centaur rocket that has a renowned history dating back some 52 years to 1962 with multiple variations.
And tonight’s blastoff of the Multi-User Objective System (MUOS-3) satellite for the US Navy involves using the most powerful variant of the rocket, known as the Atlas V 551.
Liftoff of MUOS-3 is set for 7:43 p.m. EDT from Space Launch Complex-41 at Cape Canaveral Air Force Station in Florida. The launch window extends for 44 minutes and the weather outlook is very favorable. It will be carried live on a ULA webcast.

The second ULA launch of 2015 comes just over 1 week later on January 29, lofting NASA’s SMAP Earth observation satellite on a Delta II rocket from Vandenberg Air Force Base in California.
MUOS is a next-generation narrowband tactical satellite communications system designed to significantly improve ground communications for U.S. forces on the move, according to ULA.
This is the third satellite in the MUOS series and will provide military users 10 times more communications capability over existing systems, including simultaneous voice, video and data, leveraging 3G mobile communications technology.
ULA’s second launch in 2015 thunders aloft from the US West Coast with NASA’s Soil Moisture Active Passive mission (SMAP). It is the first US Earth-observing satellite designed to collect global observations of surface soil moisture.
SMAP will blastoff from Space Launch Complex 2 at Vandenberg AFB at 9:20 a.m. EST (6:20 a.m. PST) on ULA’s Delta II rocket.

“It goes without saying: ULA had a banner year,” Bruno said. “As we look ahead to 2015, we could not be more honored to continue supporting our nation in one of the most technologically complex, critical American needs: affordable, reliable access to space.”
ULA began operations in December 2006 with the merger of the expendable launch vehicle operations of Boeing and Lockheed Martin.
ULA’s Delta IV Heavy is currently the world’s most powerful rocket and flawlessly launched NASA’s Orion capsule on Dec. 5, 2014 on its highly successful uncrewed maiden test flight on the EFT-1 mission.
Overall, the 14-mission launch manifest in 2014 included 9 national security space missions, 3 space exploration missions, including NASA’s Orion EFT-1 and 2 commercial missions.

Beyond MUOS-3 and SMAP, the launch manifest on tap for 2015 also includes additional NASA science satellites, an ISS commercial cargo resupply mission as well as more GPS satellites for military and civilian uses and top secret national security launches using the Delta II, Delta IV and the Atlas V boosters.
NASA’s Magnetospheric Multiscale Mission (MMS) to study Earth’s magnetic reconnection is scheduled for launch on an Atlas V 421 booster on March 12 from Cape Canaveral.

Ceres compared to asteroids visited to date, including Vesta, Dawn's mapping target in 2011. Image by NASA/ESA. Compiled by Paul Schenck.
When the Dawn mission was in its planning stages, Ceres was considered an asteroid. But in 2006, a year before the mission launched, the International Astronomical Union formed a new class of solar system objects known as dwarf planets, and since by definition a dwarf planet is spherical and travels in an orbit around the Sun, Ceres fit that definition perfectly.
But since it’s located in the Asteroid Belt, we still tend to think of Ceres as an asteroid. So, how does Ceres compare to other asteroids?
Dr. Paul Schenk, who is a participating scientist on the Dawn mission, recently put together some graphics on his website and the one above compares Ceres to other asteroids that we’ve visited with spacecraft.
Of course, Ceres is bigger (it’s the biggest object in the Asteroid Belt) and more spherical than the other asteroids. When it comes right down to it, Ceres doesn’t look much like an asteroid at all!
“Ceres is most similar in size to several of Saturn’s icy moons and may be similar internally as well, being composed of 25% water ice by mass,” Schenk noted on his website.

And water is one of the most interesting and mysterious aspects of Ceres. A year ago, the Herschel space telescope discovered water vapor around Ceres, and the vapor could be emanating from water plumes — much like those that are on Saturn’s moon Enceladus – or it could be from cryovolcanism from geysers or icy volcano.
“The water vapor question is one of the most interesting things we will look for,” Schenk told Universe Today. “What is its source, what does it indicate about the interior and activity level within Ceres? Is Ceres active, very ancient, or both? Does it go back to the earliest Solar System? Those are the questions we hope to answer with Dawn.”
Some scientists also think Ceres may have an ocean and possibly an atmosphere, which makes Dawn’s arrival at Ceres in March one of the most exciting planetary events of 2015, in addition to New Horizon’s arrival at Pluto.
“Since we don’t know why the water vapor venting has happened, or even if it continues, it’s hard to say much more than that,” Schenk said via email, “but it is theoretically possible that some liquid water still exists within Ceres. Dawn will try to determine if that is true.”
One of the possibilities that has been discussed is that if the water vapor is confirmed, Ceres could potentially host microbial life. I asked Schenk what other factors would have to be present in order for that to have occurred?
“The presence of carbon molecules is often regarded as necessary for life,” he replied, “and we think we see that on the surface spectroscopically in the form of carbonates and clays. So, I think the questions will be, whether there is actually liquid water of any kind, whether the carbon compounds are just a surface coating or in the interior, and whether Ceres has ever been warm. If those are true then some sort of prebiotic or biotic activity is in play.”
Since we do not know the answer to any of these questions yet, Schenk says Dawn’s visit to Ceres should be interesting!
On thing of note is that Dawn is now closing in on Ceres and just today, the team released the best image we have yet of Ceres, which you can see in our article here.

For DSCOVR – the payload of SpaceX’s next Falcon 9 launch, waiting one more week is a yawn. The Deep Space Climate Observatory (DSCOVR) spacecraft has withstood a delay of over 12 years. Word from Cape Canaveral is that the Air Force is delaying the launch of the next Falcon 9 until February 9th. Two days earlier, the launch date had been moved to January 31st.
Its original mission name could not be more noble, Triana – the name of Columbus’ sailor that first saw the New World. Then, it got tangled in the ignoble politics of space and climate change. Yet, if all goes well for the SpaceX Falcon 9 launch, the famous GoreSat satellite will be deployed and then immediately upstaged by what everyone agrees is a major milestone – returning a rocket’s 1st stage gently to Earth to reuse and to reduce the cost of space travel.

Remember GoreSAT? Better yet, do you recall the spacecraft Triana? They are one in the same. They are DSCOVR. The spacecraft was completed and ready to be shipped to Cape Canaveral in 2001. It was scheduled for launch on board NASA’s flagship, the Space Shuttle Columbia, on what became Columbia’s ill-fated last mission in January 2003. But DSCOVR had become the spoils of the victor. Bush had defeated Gore and the victor pulled the rug from under Triana.
The political story of the DSCOVR spacecraft is wrapped in the political tug of war over Climate Change. Senator Al Gore had long recognized the risks to humanity, to species extinction and destruction of ecosystems by the human-caused climate change. As vice president, in 1998, Gore proposed to NASA the concept that became Triana to monitor and better understand Climate Change. His political opponents labeled Triana “GoreSat”, and its constant downlink stream of “Whole Earth” images as “an expensive screensaver”.
The former Republican congressman from Texas, Dick Armey, referring to GoreSat, said, “This idea supposedly came from a dream. Well, I once dreamed I caught a 10-foot bass. But I didn’t call up the Fish and Wildlife Service and ask them to spend $30 million to make sure it happened.” This was the rash and risk beholding a spacecraft conceived by politicians. However, while political egos were bruised, Triana, now DSCOVR, was never damaged and was placed into cold storage and for two Bush terms was bathed in pure nitrogen gas to minimize any damage to electronics.
The DSCOVR spacecraft (3-axis stabilized, 570 kg) will be delivered to the Sun-Earth L1 point, 1.5 million km (1 million miles) from the Earth, directly in front of the Sun. A Halo (Lissajous) orbit will stabilize the craft’s position around the L1 point while keeping it outside the radio noise emanating from the Sun. (Illustratin Credit: NASA)
While Solar radiation causes skin damage and melanoma, Solar eruptions – Coronal Mass Ejections (CME) have a global impact – disruption of electrical power grids and damage to Earth orbiting spacecraft. Just as California expects the “big one” and plans for large quakes, DSCOVR is meant to give the Earth an early warning system. According to NOAA and NASA, without monitoring upwind, the big one will cost upwards of $2 trillion in damages including a breakdown of power grids and major satellite systems that the world depends on for transportation, GPS, telecommunications and commerce. In time, a massive CME will happen.
As sure as the Sun rises every morning, DSCOVR was pulled out of storage in November 2008. Despite the years of idle time and technological advances passing it by, DSCOVR still holds an excellent array of instruments. The National Research Council was commissioned to analyze and reported to Congress that Triana was “Strong and scientifically vital.” Beginning in 2009, the instruments were re-certified for flight re-integrated onto the spacecraft bus. Filters were replaced on the 30 cm (12 inch) telescopic camera.
DSCOVR’s Earth Polychromatic Imaging Camera (EPIC) will provide a first of its kinds continuous stream of 8 km resolution global images of the rotating sunlit Earth. The images in 3 bands are in contrast to the future geostationary GOES-R weather satellites (a pair) which will have a 0.5 and 1 km resolution images but only for the western hemisphere. DSCOVR will pair up with ACE to monitor particles and fields streaming from the Sun towards the Earth, 1.5 million km (1 million miles) away.
Three particle and fields instruments will monitor electrons and ions – a top-hat electron electrostatic analyzer and a Farday Cup ion detector; the same type of detectors that were recently flown on the Philae lander to comet 67P. The third Plasma instrument is a pair of fluxgate magnetometers designed and constructed by the late Dr. Mario Acuna’s magnetometer team at Goddard Spaceflight Center. Lastly, targeting its interest in Climate Change, the NiStar instrument developed at Ball Aerospace “is a cavity radiometer designed to measure the absolute, spectrally integrated irradiance reflected and emitted from the entire sunlit face of the Earth”, as stated in NOAA documentation.

DSCOVR now becomes the legacy to a long line of Solar-Terrestial monitoring spacecraft. If you recall last August 10th, the spacecraft ISEE-3 flew past the Earth after over 20 years out of contact and 35 years in space. ISEE-3 became the first vehicle to utilize the Sun-Earth Lagrangian point 1 (L1) to monitor the Solar wind. Several vehicles followed, specialized probes even clusters were developed to understand the complex interaction between the Sun and the Earth’s magnetic field and atmosphere.
DSCOVR will join two existing vehicles – the aging Advanced Composition Explorer (ACE) and the Solar Dynamics Observatory (SDO). Altogether, a next generation of monitoring and, as NOAA emphasizes, development of space weather forecasting and a warning system will evolve from addition of DSCOVR. This also represents SpaceX first contracted launch in the Orbital/Suborbital Program (OSP)-3 NASA program. The second contracted (OSP)-3 launch will be atop the Falcon Heavy expected later in 2015.

Dramatic new photos and video of the daring and mostly successful attempt by Space X to land their Falcon 9 booster on an ocean-going “drone ship” were released this morning, Friday, Jan. 16, by SpaceX CEO and founder Elon Musk.
Musk posted the imagery online via his twitter account and they vividly show just how close his team came to achieving total success in history’s first attempt to land and recover a rocket on a tiny platform in the ocean.
Here’s the video: “Close, but no cigar. This time.”
The history making attempt at recovering the Falcon 9 first stage was a first of its kind experiment to accomplish a pinpoint soft landing of a rocket onto a miniscule platform at sea using a rocket assisted descent by the first stage Merlin engines aided by steering fins.
The first stage rocket reached an altitude of over 100 miles after firing nine Merlins as planned for nearly three minutes. It had to be slowed from traveling at a velocity of about 2,900 mph (1300 m/s). The descent maneuver has been likened to someone balancing a rubber broomstick on their hand in the middle of a fierce wind storm.
The imagery shows the last moments of the descent as the rocket hits the edge of the drone ship at a 45 degree angle with its four landing legs extended and Merlin 1D engines firing.

Musk tweeted that the first stage Falcon 9 booster ran out of hydraulic fluid and thus hit the barge.
“Rocket hits hard at ~45 deg angle, smashing legs and engine section,” Musk explained today.
Lacking hydraulic fluid the boosters attached steering fins lost power just before impact.
“Before impact, fins lose power and go hardover. Engines fights to restore, but …,” Musk added.

This ultimately caused the Falcon 9 to crash land as the legs and engine section were smashed and destroyed as the fuel and booster burst into flames. The ship survived no problem.
“Residual fuel and oxygen combine.”
“Full RUD (rapid unscheduled disassembly) event. Ship is fine minor repairs. Exciting day!” said Musk.
“Rocket made it to drone spaceport ship, but landed hard. Close, but no cigar this time. Bodes well for the future tho,” Musk tweeted within hours after the launch and recovery attempt.
As I wrote on launch day here at Universe Today, despite making a ‘hard landing’ on the vessel dubbed the ‘autonomous spaceport drone ship,’ the 14 story tall Falcon 9 first stage did make it to the drone ship, positioned some 200 miles offshore of the Florida-Carolina coast, northeast of the launch site in the Atlantic Ocean. The rocket broke into pieces upon hitting the barge.
Whereas virtually every other news outlet quickly declared the landing attempt a “Failure” in the headline, my assessment as a scientist and journalist was the complete opposite!!
In my opinion the experiment was “a very good first step towards the bold company goal of recovery and re-usability in the future” as I wrote in my post launch report here at Universe Today.
Listen to my live radio interview with BBC 5LIVE conducted Saturday night (Jan. 11 UK time), discussing SpaceX’s first attempt to land and return their Falcon-9 booster.
“Is it safe? Was SpaceX brave or foolhardy? Why is this significant? Will SpaceX succeed in the future?” the BBC host asked me.
SpaceX achieved virtually all of their objectives in the daunting feat except for a soft landing on the drone ship.
This was a bold experiment involving re-lighting one of the first stage Merlin 1D engines three times to act as a retro rocket to slow the stages descent and aim for the drone ship.
Four attached hypersonic grid fins and a trio of Merlin propulsive burns succeeded in slowing the booster from hypersonic velocity to subsonic and guiding it to the ship.
The drone ship measures only 300 feet by 170 feet. That’s tiny compared to the Atlantic Ocean.
The first stage was planned to make the soft landing by extending four landing legs to a width of about 70 feet to achieve an upright landing on the platform with a accuracy of 30 feet (10 meters).
No one has ever tried such a landing attempt before in the ocean says SpaceX. The company has conducted numerous successful soft landing tests on land. And several soft touchdowns on the ocean’s surface. But never before on a barge in the ocean.
So they will learn and move forward to the next experimental landing, that could come as early as a few weeks on the launch of the DSCOVR mission in late January or early February.
“Upcoming flight already has 50% more hydraulic fluid, so should have plenty of margin for landing attempt next month.”

Musk’s daring vision is to recover, refurbish and reuse the first stage and dramatically reduce the high cost of access to space, by introducing airline like operational concepts.
It remains to be seen whether his vision of reusing rockets can be made economical. Most of the space shuttle systems were reused, except for the huge external fuel tanks, but it was not a cheap proposition.
But we must try to cut rocket launch costs if we hope to achieve routine and affordable access to the high frontier and expand humanity’s reach to the stars.
The Falcon 9 launch itself was a flawless success, blasting off at 4:47 a.m. EST on Jan. 10 from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.
The Dragon CRS-5 spacecraft was loaded with over 5108 pounds (2317 kg) of scientific experiments, technology demonstrations, the CATS science payload, student research investigations, crew supplies, spare parts, food, water, clothing and assorted research gear for the six person crew serving aboard the ISS.
It successfully rendezvoused at the station on Jan. 12 after a two day orbital chase, delivering the critical cargo required to keep the station stocked and humming with science.

The final chapter in the saga of a wayward Mars lander was finally revealed today, as an international team released images showing the Beagle-2 lander’s final resting place on Mars.
Flashback to Christmas Day, 2003. While most folks gathered ‘round the tree and opened presents, the UK and European Space Agency awaited a gift from space. The Beagle-2 Mars lander had been released from the European Space Agency’s Mars Express orbiter six days prior, and was coasting towards a perilous landing in Isidis Planitia and was set to phone home.
All was going according to plan, and then… silence.
It’s the worst part of any mission, waiting for a lander to call back and say that it’s safe and sound on the surface of another world. As the hours turned into days, anxious engineers used NASA’s Mars Odyssey spacecraft and the Lovell Telescope at Jodrell Bank to listen for the signal.
Beagle-2 was declared lost a few weeks later on February 6th, 2004.
But now, there’s a final twist to the tale to tell.

The UK Space Agency, working with ESA and NASA announced today that debris from the landing site had been identified and that indicates — contrary to suspicions — that Beagle-2 did indeed make it to the surface of the Red Planet intact. New images from the Mars Reconnaissance Orbiter released today suggest that not only did Beagle-2 land, but that its airbags did indeed deploy properly and that the dish-shaped 1-meter in diameter spacecraft partially unfolded pocket-watch style after it had bounced to a stop.
“We are very happy to learn that Beagle 2 touched down on Mars,” said ESA’s Director of Science and Robotic Exploration in a recent press release. “The dedication of the various teams in studying high-resolution images in order to find the lander is inspiring.”
So, what went wrong with Beagle-2?
At this point, no further speculation as to what caused the lander to fall silent has been forthcoming, but today’s revelation is sure to rewrite the final saga of Beagle-2.
“Not knowing what happened to Beagle-2 remained a nagging worry,” said ESA’s Mars Express project manager Rudolf Schmidt. “Understanding now that Beagle-2 made it all the way down to the surface is excellent news.”
Speculation swirled across the internet earlier this week as the UK Space Agency and ESA suggested that new information as to the fate of Beagle-2 was forthcoming, over 11 years after the incident. Back in 2004, it was suggested that Beagle-2 had encountered higher levels of dust in the Martian atmosphere than expected, and that this in turn resulted in a failure of the spacecraft’s parachutes. Presumably, the lander then failed to slow down sufficiently and crashed on the surface of Mars, the latest victim of the Great Galactic Ghoul who seems to love dining on human-built spacecraft bound for the Red Planet.

The loss of Beagle-2 wasn’t only a blow to the UK and ESA, but to its principal investigator Colin Pillinger as well. Pillinger was involved in the search for Beagle-2 in later years, and also played a part in the Rosetta mission to Comet 67P/Churyumov-Gerasimenko as well. Unfortunately, Pillinger passed away in May of last year from a brain hemorrhage. A portion of the western rim of Endeavour Crater currently being explored by Opportunity was named Pillinger Point in his honor.
Today’s announcement has triggered a wave of congratulations that the 11-year mystery has been solved. There have even been calls on Twitter and social media to rename the Beagle-2 site Pillinger Station.
“The history of of space exploration is marked by both success and failure,” Said Dr. David Parker, the Chief Executive of the UK Space Agency in a recent press release. “This finding makes the case that Beagle-2 was more of a success than we previously knew and undoubtedly an important step in Europe’s continuing exploration of Mars.”

Beagle-2 is about 2 metres across unfurled, and came to rest within 5 kilometres of its target location.
There have been false announcements of the discovery of Beagle-2 before. Back in late 2005, a claim was made that the lander had been spotted by Mars Global Surveyor, though later searches came to naught.
“I can imagine the sense of closure that the Beagle-2 team must feel,” Said JPL’s MRO project scientist Richard Zurek in a recent press release. “MRO has helped find safe landing sites on Mars for the Curiosity and Phoenix missions and has searched for missing craft to learn what may have gone wrong. It’s an extremely difficult task.”
MRO entered orbit in March 2006 and carries a 0.5 metre in diameter HiRISE camera capable of resolving objects just 0.3 metres across on the surface of Mars. The European Space Agency’s Mars Express orbiter that carried Beagle 2 is also still in operation, along with NASA’s aging Mars Odyssey spacecraft. These were joined in orbit by MAVEN and India’s Mars Orbiter just last year.

Of course, getting to Mars is tough, and landing is even harder. Mars has just enough atmosphere that you have to deal with it, but it’s so tenuous – 0.6% the surface pressure of Earth’s atmosphere at sea level – That it doesn’t provide a whole lot of usable drag.
To date, only NASA had successfully landed on Mars, and done it seven times – only the Mars Polar Lander failed back in 1999. The Russians fared much worse, with their most successful lander being Mars 3, which sent back only one blurry image before falling silent.
ESA and the Russian Federal Space Agency hope to amend that with the launch of the ExoMars mission next year, slated to land on Mars in 2018.
I remember waiting with millions of other space fans for word back from Beagle 2 on Christmas Day 2003. Think back to what your internet connection was like over 11 years ago, in an era before smart phones, Twitter and Facebook. We’d just come off of the spectacular 2003 Mars opposition season, which provided the orbital geometry ideal for launching a mission to the Red Planet. This window only comes around once every 26 months.
Though Beagle 2 was a stationary lander akin to the Viking and Mars Phoenix missions, it had a robotic arm and a clever battery of experiments, including ones designed to search for life. The signal it was supposed to use to call home was designed by the UK pop rock band Blur, a jingle that never came.
Alas, we’ll have to wait to see what the alien plains around Isidis Planitia actually look like, just 13 degrees north of the Martian equator. But hey, a lingering mystery of the modern age of planetary exploration was solved this week.
Still, we’re now left with a new dilemma. Does this mean we’ll have to write a sequel to our science fiction short story The Hunt for Beagle?

NASA’s goal of sending astronauts to deep space took a major step forward when the first engine of the type destined to power the mighty Space Launch System (SLS) exploration rocket blazed to life during a successful test firing at the agency’s Stennis Space Center near Bay St. Louis, Mississippi.
The milestone hot fire test conducted on Jan. 9, involved igniting a shuttle-era RS-25 space shuttle main engine for 500 seconds on the A-1 test stand at Stennis.
A quartet of RS-25s, formerly used to power the space shuttle orbiters, will now power the core stage of the SLS which will be the most powerful rocket the world has ever seen.
“The RS-25 is the most efficient engine of its type in the world,” said Steve Wofford, manager of the SLS Liquid Engines Office at NASA’s Marshall Space Flight Center, in Huntsville, Alabama, where the SLS Program is managed. “It’s got a remarkable history of success and a great experience base that make it a great choice for NASA’s next era of exploration.”
The SLS is NASA’s mammoth heavy lift rocket now under development. It is intended to launch the Orion deep space crew capsule and propel astronauts aboard to destinations far beyond Earth and farther into space than ever before possible – beyond the Moon, to Asteroids and Mars.
The over eight minute RS-25 engine test firing provided NASA engineers with critical data on the engine controller unit, which is the “brain” of the engine providing communications between the engine and the vehice, and inlet pressure conditions.
“The controller also provides closed-loop management of the engine by regulating the thrust and fuel mixture ratio while monitoring the engine’s health and status. The new controller will use updated hardware and software configured to operate with the new SLS avionics architecture,” according to NASA.
This also marked the first test of a shuttle-era RS-25 since the conclusion of space shuttle main engine testing in 2009.
For the SLS, the RS-25 will be configured and operated differently from their use when attached as a trio to the base of the orbiters during NASA’s four decade long Space Shuttle era that ended with the STS-135 mission in July 2011.
“We’ve made modifications to the RS-25 to meet SLS specifications and will analyze and test a variety of conditions during the hot fire series,” said Wofford
“The engines for SLS will encounter colder liquid oxygen temperatures than shuttle; greater inlet pressure due to the taller core stage liquid oxygen tank and higher vehicle acceleration; and more nozzle heating due to the four-engine configuration and their position in-plane with the SLS booster exhaust nozzles.”

The SLS core stage stores the cryogenic liquid hydrogen and liquid oxygen that fuel the RS-25 first stage engines.
“This first hot-fire test of the RS-25 engine represents a significant effort on behalf of Stennis Space Center’s A-1 test team,” said Ronald Rigney, RS-25 project manager at Stennis.
“Our technicians and engineers have been working diligently to design, modify and activate an extremely complex and capable facility in support of RS-25 engine testing.”
The Jan. 9 engine test was just the first of an extensive series planned. After an upgrade to the high pressure cooling system, an initial series of eight development tests will begin in April 2015 totaling 3,500 seconds of firing time.

The SLS core stage is being built at NASA’s Michoud Assembly Facility in New Orleans.
On Sept. 12, 2014, NASA Administrator Charles Bolden officially unveiled the world’s largest welder at Michoud, that will be used to construct the core stage, as I reported earlier during my on-site visit.
“This rocket is a game changer in terms of deep space exploration and will launch NASA astronauts to investigate asteroids and explore the surface of Mars while opening new possibilities for science missions, as well,” said NASA Administrator Charles Bolden during the ribbon-cutting ceremony at Michoud.
The core stage towers over 212 feet (64.6 meters) tall and sports a diameter of 27.6 feet (8.4 m).

The maiden test flight of the SLS is targeted for no later than November 2018 and will be configured in its initial 70-metric-ton (77-ton) version with a liftoff thrust of 8.4 million pounds. It will boost an unmanned Orion on an approximately three week long test flight beyond the Moon and back.
NASA plans to gradually upgrade the SLS to achieve an unprecedented lift capability of 130 metric tons (143 tons), enabling the more distant missions even farther into our solar system.
The first SLS test flight with the uncrewed Orion is called Exploration Mission-1 (EM-1) and will launch from Launch Complex 39-B at the Kennedy Space Center.
Orion’s inaugural mission dubbed Exploration Flight Test-1 (EFT) was successfully launched on a flawless flight on Dec. 5, 2014 atop a United Launch Alliance Delta IV Heavy rocket Space Launch Complex 37 (SLC-37) at Cape Canaveral Air Force Station in Florida.

Anyone who’s ever read a Charlie Brown comic strip knows “Pig-Pen”, the lovable boy who walks around in a constant cloud of his own dirt and dust. Every time he sighs, dust rises in a little cloud around him. Why bother to bathe? There’s dignity in debris, which “Pig-Pen refers to as the “dust of countless ages”. Comets shuffle around the Sun surrounded by a similar cloud of grime that’s as old as the Solar System itself.
Dust and gases released by the comet reflect so little light compared to the nucleus they require special processing to see clearly. In this photo, many of the small, irregular specks may be cometary dust grains captured in the 4.3 second exposure. Credit: ESA/Rosetta/NAVCAM
You’ve probably noticed little flecks and streaks in photos returned by the Rosetta spacecraft in the blackness of space surrounding comet 67P/Churyumov-Gerasimenko. After a recent year-end break, the Rosetta team has returned with new updates on the comet including a series of four images recently released as a mosaic. The pictures were processed to highlight surface features; the space around the nucleus is black in comparison. But if we take a closer look at what first appears void, we soon discover it’s not empty at all.
In photos taken January 3rd, the writer of ESA’s Rosetta blog notes that “some of the streaks and specks seen around the nucleus will likely be dust grains ejected from the comet, captured in the 4.3 second exposure time.”

Using an image-editing tool like Photoshop, we can hold back the glare of the nucleus and “open up” the shadows around the comet. Jets of dust released by vaporizing ice are the most obvious features to emerge. The soft, low-contrast plumes plow into the vacuum around the nucleus wrapping it in a silky cocoon of gas and dust – a tenuous atmosphere that reflects sunlight far more weakly than the comet itself.

While staring at dust spots may not produce the same magical feelings as watching a sunrise, it’s fascinating nonetheless to contemplate what we’re seeing. If you’ve been struck by the beauty of a comet’s meteor-like head trailing a wispy tail, you’re looking at what countless individual grains of dust can do when sculpted by the master hand of the Sun. Perusing images of 67P, we see the process in its infancy as individual grains and small clots are released into space to be fashioned into something grander.

Rosetta’s Micro-Imaging Dust Analysis System or MIDAS measures the rate at which dust sweeps past the spacecraft and its size distribution. MIDAS catches dust grains by exposing a sticky target surface into space and waiting for a mote to drift by. It snatched its first one last November – a larger than expected mote measuring about 1/100 of a millimeter across with a complex shape and fluffy texture.

Analysis of the composition of another dust grain named “Boris” made by the COSIMA instrument has identified sodium and magnesium. Magnesium is no surprise as 95% of known minerals observed in comets resemble olivine and pyroxenes, common in meteorites and in the upper mantle of the Earth. Sodium has also been seen before in comas and tails, and originates in dust grains, but its mineral source remains uncertain.
As we might study the makeup of the dust Pig-Pen leaves in his wake to identify traces of earthly dirt, micro-organisms, pollen, pollution, and even recent volcanic eruptions, so we examine each mote that sprays Rosetta’s way, looking for clues to the origin of the planets and Solar System.

The New Horizons spacecraft is now just a few months away from its encounter with Pluto and the Kuiper Belt, arriving in July, 2015. Back in 2008, the New Horizons team revealed the secret stowaways they had hidden on board the spacecraft. Nine objects (can you guess why there are nine?!) were attached and sent along on the ten-year journey to the outer reaches of our Solar System. Believe it or not, included in the items are one actual person, and parts of several thousands of other people…
Here’s the complete list:
1. One actual person. Well, part of an actual person. A portion of Pluto discoverer Clyde Tombaugh’s ashes were put in a container and attached to the underside of the spacecraft – see image above. Here’s the inscription on the container: “Interned herein are remains of American Clyde W. Tombaugh, discoverer of Pluto and the solar system’s ‘third zone’ Adelle and Muron’s boy, Patricia’s husband, Annette and Alden’s father, astronomer, teacher, punster, and friend: Clyde W. Tombaugh (1906-1997).”
2. Me and about 434,000 other people, too! The “Send Your Name to Pluto” CD-ROM with more than over four hundred thousand names of people who wanted to participate in this great journey of exploration. I’m pumped about being along for the ride, and I hope you are on board, too!
3. A CD-ROM with pictures of New Horizons project personnel.
4. A Florida state quarter, from the state where New Horizons was launched.
5. A Maryland state quarter, from the state where New Horizons was built.
6. A small piece cut from SpaceShip One is installed on New Horizons’ lower inside deck, with a two-sided inscription. Front: “To commemorate its historic role in the advancement of spaceflight, this piece of SpaceShip One is being flown on another historic spacecraft: New Horizons. New Horizons is Earth’s first mission to Pluto, the farthest known planet in our solar system.” Back: “SpaceShip One was Earth’s first privately funded manned spacecraft.

New Horizons’ principal investigator Dr. Alan Stern disclosed the list of items at a ceremony at Smithsonian National Air and Space Museum’s Udvar-Hazy Center, where a model of the New Horizons spacecraft was added to the museum. Back in 2008, Stern petitioned the U.S. Postal Service to issue a new stamp for Pluto after the spacecraft arrived at Pluto, maybe something like this: Proposed new stamp for New Horizons.

We originally wrote this in 2008, but we thought you’d get a kick out of it since New Horizons is so close. We made a couple of updates to the text.

SpaceX successfully launched their commercial Falcon 9 rocket and Dragon cargo ship on a critical mission for NASA bound for the space station this morning, Jan. 10, while simultaneously accomplishing a hard landing of the boosters first stage on an ocean-floating “drone ship” platform in a very good first step towards the bold company goal of recovery and re-usability in the future.
The spectacular night time launch of the private SpaceX Falcon 9 rocket lit up the skies all around the Florida Space Coast and beyond following a flawless on time liftoff at 4:47 a.m. EST from Cape Canaveral Air Force Station.
The nine Merlin 1D engines of the 208 foot-tall Falcon 9 generated 1.3 million pounds of liftoff thrust as the rocket climbed to orbit on the first SpaceX launch of 2015.
The Dragon CRS-5 mission is on its way to a Monday-morning rendezvous with the International Space Station (ISS).
It is loaded with more than two tons of supplies and NASA science investigations for the six person crew aboard the massive orbiting outpost.
A secondary goal of SpaceX was to conduct a history-making attempt at recovering the 14 story tall Falcon 9 first stage via a precision landing on an ocean-going landing platform known as the “autonomous spaceport drone ship.”
SpaceX CEO Elon Musk quickly tweeted that good progress was made, and as expected, more work needs to be done.
This was an experiment involving re-lighting one of the first stage Merlin engines three times to act as a retro rocket to slow the stages descent and aim for the drone ship.
“Rocket made it to drone spaceport ship, but landed hard. Close, but no cigar this time. Bodes well for the future tho,” Musk tweeted soon after the launch and recovery attempt.
“Ship itself is fine. Some of the support equipment on the deck will need to be replaced…”
“Didn’t get good landing/impact video. Pitch dark and foggy. Will piece it together from telemetry and … actual pieces.”
Musk’s daring vision is to recover, refurbish and reuse the first stage and dramatically reduce the high cost of access to space, by introducing airline like operational concepts.
The ‘autonomous spaceport drone ship’ was positioned some 200 to 250 miles offshore of the launch site in the Atlantic Ocean along the rockets flight path, flying along the US Northeast coast to match that of the ISS.
The autonomous spaceport drone ship measure only 300 by 100 feet, with wings that extend its width to 170 feet. That’s tiny compared to the Atlantic Ocean.
Therefore the SpaceX team was successful in accomplishing a rocket assisted descent and pinpoint landing in the middle of a vast ocean, albeit not as slow as hoped.
No one has ever tried such a landing attempt before in the ocean says SpaceX. The company has conducted numerous successful soft landing tests on land. And several soft touchdowns on the ocean’s surface. But never before on a barge in the ocean.
So they will learn and move forward to the next experimental landing.

CRS-5 marks the company’s fifth resupply mission to the ISS under a $1.6 Billion contract with NASA to deliver 20,000 kg (44,000 pounds) of cargo to the station during a dozen Dragon cargo spacecraft flights through 2016 under NASA’s Commercial Resupply Services (CRS) contract.
“We are delighted to kick off 2015 with our first commercial cargo launch of the year,” said NASA Administrator Charles Bolden in a statement.
“Thanks to our private sector partners, we’ve returned space station resupply launches to U.S. soil and are poised to do the same with the transport of our astronauts in the very near future.”
“Today’s launch not only resupplies the station, but also delivers important science experiments and increases the station’s unique capabilities as a platform for Earth science with delivery of the Cloud-Aerosol Transport System, or CATS instrument. I congratulate the SpaceX and NASA teams who have made today’s success possible. We look forward to extending our efforts in commercial space to include commercial crew by 2017 and to more significant milestones this year on our journey to Mars.”
The Dragon CRS-5 spacecraft is loaded with over 5108 pounds (2317 kg) of scientific experiments, technology demonstrations, crew supplies, spare parts, food, water, clothing, and assorted research gear for the six person crew serving aboard the ISS.
The launch marked the first US commercial resupply launch since the catastrophic destruction of an Orbital Sciences Antares rocket and Cygnus Orb-3 spacecraft bound for the ISS exploded unexpectedly after launch from NASA Wallops, VA, on Oct. 28, 2014.
The US supply train to the ISS is now wholly dependent on SpaceX until Cygnus flights are resumed hopefully by late 2015 on an alternate rocket, the Atlas V.
