Elon Musk Releases Dramatic Imagery of Mostly Successful Falcon 9 1st Recovery Attempt, Hard Landing on Drone Ship

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 rocket landing and recovery attempt was a secondary objective of SpaceX, that immediately followed the spectacular nighttime blastoff of the Falcon 9 on Jan. 10 carrying the SpaceX Dragon cargo freighter spacecraft on a critical resupply mission for NASA bound for the space station.

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.

I replied; “It was a 99% success” and more …..

“Am super proud of my crew for making huge strides towards reusability on this mission. You guys rock!” Musk declared in a later tweet.

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.

Beagle 2: Found on Mars After An 11 Year Hunt

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 6^th, 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.

All rights reserved Beagle 2. — Beagle-2 encapsulated in the lab. All rights reserved, Beagle-2.

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?

First SLS Engine Blazes to Life in Mississippi Test Firing Igniting NASA’s Path to Deep Space

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.”

Watch this video of the RS-25 engine test:

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.

Astronauts Safely Back inside US Space Station Segment after False Ammonia Leak Alarm

Nearly twelve hours after the threat of a leak of toxic ammonia forced the crew into a middle of the night evacuation from the US side of the International Space Station this morning (Jan. 14) and a hatch closure, top level managers from the partner space agencies gave the all clear and allowed the astronauts and cosmonauts to reopen access to the American portion of the orbiting outpost.

The six person crew hailing from the US, Italy and Russia were allowed to open the sealed hatch to the U.S. segment later this afternoon after it was determined that the ammonia leak was quite fortunately a false alarm.

No ammonia leak was actually detected. But the crew and mission control had to shut down some non essential station systems on the US segment in the interim.

All the Expedition 42 crew members were safe and in good health and never in danger, reported NASA.

The station crews and mission control teams must constantly be prepared and train for the unexpected and how to deal with potential emergencies, such as today’s threat of a serious chemical leak.

After a thorough review of the situation by the International Space Station mission management team, the crew were given the OK by flight controllers to head back.

They returned inside at 3:05 p.m. EST. Taking no chances, they wore protective masks and sampled the cabin atmosphere and reported no indications of any ammonia.

Fears that a leak had been detected resulted from the sounding of an alarm at around 4 a.m. EST.

The alarm forced Expedition 42 station commander Barry Wilmore and Flight Engineer Terry Virts of NASA and Flight Engineer Samantha Cristoforetti of the European Space Agency to don protective gas masks and move quickly into the Russian segment, sealing the hatch behind them to the US segment.

Inside the Russian segment, they joined the remainder of Expedition 42, namely cosmonauts Aleksandr Samokutyayev, Yelena Serova, and Anton Shkaplerov from Russia, also living and working aboard the ISS and rounding out the crew of four men and two women.

“The alarm is part of the environmental systems software on the station designed to monitor the cabin’s atmosphere. At the same time, the station’s protection software shut down one of two redundant cooling loops (Thermal Control System Loop B),” NASA said in an update.

Ammonia is a toxic substance used as a coolant in the stations complex cooling system that is an essential requirement to continued operation of the station.

Ammonia is a gas at room temperature that is extremely dangerous to inhale or when it comes in contact with skin, eyes and internal organs.

Precautions must be taken if a leak is feared in a confined space such as the ISS. It has about the same habitable volume as a four bedroom house.

As a professional chemist, I’ve worked frequently with ammonia in research and development labs and manufacturing plants and know the dangers firsthand. It can cause severe burns and irritations and worse.

There have been prior ammonia leaks aboard the ISS facility that forced a partial evacuation similar to today’s incident.

The ISS has been continuously occupied by humans for 15 years.

In the case of a life threatening emergency, the crew can rapidly abandon the station aboard the two docked Russian Soyuz capsules. They hold three persons each and serve as lifeboats.

Fortunately, the perceived ammonia leak this morning was not real and apparently was caused by a false alarm.

“This morning’s alarm is suspected to have been caused by a transient error message in one of the station’s computer relay systems, called a multiplexer-demultiplexer. A subsequent action to turn that relay box off and back on cleared the error message and the relay box is reported by flight controllers to be in good operating condition,” according to a NASA statement.

“Meanwhile, flight controllers are continuing to analyze data in an effort to determine what triggered the alarm that set today’s actions in motion.”

“Work to reactivate cooling loop B on the station will continue throughout the night and into the day Thursday. The crew members are expected to resume a normal complement of research activities on Thursday as well.”

The evacuation came just two days after a commercial SpaceX Dragon cargo freighter successfully rendezvoused and berthed at the station on Monday, Jan. 12.

The crew had just opened the hatch to Dragon and begun unloading the goodies stored aboard.

Breaking News: A possible ammonia leak aboard the US side of the International Space Station (ISS) has forced a partial evacuation of the entire crew to the Russian side earlier this morning, Wednesday, Jan. 14.

All six crew members from the US, Italy and Russia are safe and in good shape at this time, says NASA and Roscosmos, the Russian Federal Space Agency.

Hatches between the US and Russian segments were sealed shut, pending further analysis.

Read my late day update – here.

Mission controllers are in the process of assessing whether it’s a real leak or a false alarm due to a faulty sensor or a computer problem. It’s not completely clear at this time.

The latest indications at 11 a.m. EST, Jan. 14, are that it may be a false alarm, says NASA.

“The security of a crew was guaranteed thanks to correct actions of the cosmonauts, astronauts and the crew of the Mission control centres in Moscow and Houston. Further plan of actions in the US modules must be prepared in Houston,” according to Roscosmos.

“For now NASA colleagues are analyzing situation”, – noted the head of Russian Mission Control Centre Maxim Matushin

Ammonia is a toxic substance used as a coolant in the stations complex cooling system that is an essential requirement to continued operation of the station.

There have been prior ammonia leaks aboard the ISS facility.

NASA announced that an alarm sounded in the US segment at about 4 a.m. EST. indicating a possible ammonia leak. As a result, all six Expedition 42 astronauts and cosmonauts evacuated the US segment.

“Flight controllers in Mission Control at NASA’s Johnson Space Center in Houston saw an increase in pressure in the station’s water loop for thermal control system B then later saw a cabin pressure increase that could be indicative of an ammonia leak in the worst case scenario,” according to a NASA announcement.

Therefore as a precaution after the alarm sounded earlier today, the crew was directed to isolate themselves in the Russian segment this morning while teams are evaluating the situation. The crew powered down non-essential equipment in the U.S. segment of the station according to established procedures, said NASA.

“In an exchange at 7:02 a.m. with Expedition 42 Commander Barry Wilmore of NASA, spacecraft communicator James Kelly said flight controllers were analyzing their data but said it is not yet known if the alarm was actually triggered by a leak or whether the situation was caused by a faulty sensor or by a problem in a computer relay box that sends data and commands to various systems on the station.”

The evacuation comes just two days after a commercial SpaceX Dragon cargo freighter successfully rendezvoused and berthed at the station on Monday, Jan. 11.

The ISS has been continuously occupied by humans for 15 years.

The current six person crew includes astronauts and cosmonauts from three nations; America, Russia and Italy including four men and two women serving aboard the massive orbiting lab complex.

They comprise Expedition 42 Commander Barry “Butch” Wilmore and Terry Virts from NASA, Samantha Cristoforetti from the European Space Agency (ESA) and cosmonauts Aleksandr Samokutyayev, Yelena Serova, and Anton Shkaplerov from Russia.

In the case of a life threatening emergency, the crew can rapidly abandon the station aboard the two docked Russian Soyuz capsules. They hold three persons each.

SpaceX Dragon Captured at Station Loaded with Critical Supplies and Science

The commercial SpaceX cargo Dragon, loaded with over 2.6 tons of critically needed supplies and science experiments, was captured by the crew aboard the International Space Station (ISS) this morning (Jan. 12) while soaring over the Mediterranean Sea.

The SpaceX Dragon CRS-5 cargo vessel arrived at the station following a flawless two day orbital pursuit and spectacular nighttime blastoff atop the SpaceX Falcon 9 on Jan. 10 at 4:47 a.m. EST from Cape Canaveral Air Force Station in Florida.

Note: This breaking news story is being updated. Check back frequently for updates.

Dragon was successfully berthed and bolted into place a few hours later at 8:54 a.m. EST.

Working at the robotics work station inside the seven windowed domed cupola, Expedition 42 Commander Barry “Butch” Wilmore of NASA, with the assistance of Flight Engineer Samantha Cristoforetti of the European Space Agency, successfully captured the Dragon spacecraft with the station’s Canadian-built robotic arm at 5:54 a.m. EST.

Wilmore grappled Dragon with the station’s 57-foot-long (17-meter-long) robotic arm at 5:54 a.m. EST, about 18 minutes ahead of schedule, in an operation shown live on NASA TV, back-dropped by breathtaking views of “our beautiful Earth” passing by some 260 miles (410 kilometers) below.

Among the goodies aboard are belated Christmas presents for the crew. The Falcon 9 and Dragon were originally scheduled to liftoff in December and arrive in time for the Christmas festivities.

The cargo freighter flew beneath the station to arrive at the capture point 32 feet (10 meters) away. Dragon’s thrusters were disabled at the time of grappling.

Robotics officers at Houston Mission Control then began remotely maneuvering the arm to berth Dragon at the Earth-facing port on the station’s Harmony module starting at 7:45 a.m. EST.

Dragon is being attached via the common berthing mechanism (CBM) using four gangs of four bolts apiece to accomplish a hard mate to Harmony. The overall grappling and berthing process requires a few hours.

Dragon was successfully berthed and bolted into place at 8:54 a.m. EST and its now part of the space station.

The crew will conduct leak pressure checks, remove the docking mechanism and open the hatch later today or tomorrow.

CRS-5 marks the company’s fifth operational 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.

Overall this is the sixth Dragon to arrive at the ISS.

The ISS cannot function without regular deliveries of fresh cargo by station partners from Earth.

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.

Among the payloads is the Cloud-Aerosol Transport System (CATS), a remote-sensing laser instrument to measure clouds and the location and distribution of pollution, dust, smoke, and other particulates and aerosols in the atmosphere that directly impact the global climate.

CATS is loaded aboard the unpressurized trunk of Dragon.

Also loaded onboard are 17 student experiments known collectively as the “Yankee Clipper” mission. The experiments are sponsored by the National Center for Earth and Space Science Education, which oversees the Student Spaceflight Experiments Program (SSEP) in partnership with NanoRacks LLC.

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 which 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.

Dragon will remain attached to the ISS for about four weeks until Feb. 10.

SpaceX also had a secondary objective of recovering the Falcon 9 booster’s first stage via an unprecedented precision guided landing on an ocean-going “drone.”

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 tiny platform in the middle of a vast ocean using a rocket assisted descent.

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, discussing SpaceX’s first attempt to land and return their Falcon-9 booster.

Mars One Readies For Robotic Red Planet Mission In 2018

While the world’s attention last year was focused on Mars One’s audacious plan to send people on a one-way trip to the Red Planet — not everyone thinks they’ll make it — the private organization has a much closer goal in its sights: landing a robotic mission there in 2018.

The goal is also audacious. Only NASA landers have worked for more than a few moments on the Red Planet, and even the agency it has experienced many failures along the way. Mars One is hoping to succeed using the design for the Phoenix northern mission, which is being duplicated somewhat in the upcoming 2016 Insight drill mission.

“We’re very lucky to have Lockheed Martin on the contract,” said founder Bas Lansdorp in a phone interview with Universe Today. He noted the company built the Phoenix lander, and that Mars One trusts Lockheed so much that the firm is being allowed to pick its own subcontractors for the mission.

Also on that mission will likely be the winner of a Mars One university competition to send an experiment to Mars. Called Seed, the proposal would see the first seed grown on Mars. The plant (called Arabidopsis thaliana, a common feature of space studies) would grow inside an external container that would protect it from the surrounding environment. The team is composed of students from the University of Porto, MIT Portugal and the University of Madrid.

“The Seed experiment group, they have really put a lot of effort into creating public awareness of what they are doing, and they collected a lot of votes,” Lansdorp said. While the project also had to meet stringent technical requirements, it was the efforts at public support that were an “important reason” as to why they won, he added.

But even now, their flight is not a guarantee. Seed will need to fund the development and construction of its experiment. (Flight costs are taken care of by Mars One.) Also, the group will need to pass technical milestones between now and 2018. If for some reason Seed does not make it, Mars One would instead go to one of two backup projects. These would be selected from the second- and third-place winners, which are respectively, Cyano Knights and Lettuce on Mars.

As for Mars One’s funding, the organization eventually hopes to receive money from broadcast rights and sponsorships in association with its crewed landing, which it says would take place in the 2020s. But the money required to fund a robotic mission isn’t available from that revenue source yet. Hence, the organization is seeking an upfront investment in its work to get the money ready for development.

Lansdorp said Mars One already underwent an angel investment round, and the organization is now in touch with an institutional group connected to an “institutional fund”, which would also attract money from other investors. Negotiations are ongoing, so the name is not disclosed publicly yet.

The goal is to have this investment group fund the robotic mission and the crewed one. The investor’s financial return would come from the eventual broadcasting and sponsorship revenues.

Aims of the robotic mission include testing some of the technologies that the crew would later take advantage of, such as extracting water from the planet’s underground and testing solar panels on the Martian surface.

Crew selection is ongoing. Mars One did a major culling last year of thousands of candidates, and plans a further selection round that will be announced in February.

SpaceX Launch and Historic Landing Attempt Reset to Jan. 10

The oft delayed launch of the SpaceX Falcon 9 rocket on the CRS-5 cargo resupply mission for NASA to the International Space Station (ISS) has been reset to Saturday, Jan. 10.

Liftoff is currently targeted for 4:47 a.m. EST Saturday, Jan. 10, from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida following a postponement from Friday, Jan. 9.

The launch was unexpectedly scrubbed with one minute, 21 seconds left on the countdown clock for technical reasons earlier this week just prior to the targeted blastoff time of 6:20 a.m. EST on Tuesday, Jan. 6.

A thrust vector control actuator for the Falcon 9’s second stage failed to perform as expected, resulting in a launch abort, said NASA.

NASA and SpaceX decided to take another day to fully evaluate the issue and ensure a launch success.

The launch will be the first Falcon 9 liftoff for 2015.

The overnight launch should put on a spectacular sky show for spectators along the Florida space coast.

There is only an instantaneous launch window available, meaning that the blastoff must proceed at that exact instant. Any delays due to technical issues or weather would force a scrub until at least Tuesday, Jan. 13.

Overall, CRS-5 is the company’s fifth commercial resupply services mission to the International Space Station.

In additional to being a critical cargo mission required to keep the space station stocked with provisions for the crew and research experiments, the mission features a history making attempt to recover the first stage of the Falcon 9 rocket.

The rocket recovery and landing attempt is a key step towards carrying out SpaceX CEO Elon Musk’s bold vision of rocket reusability.

Towards that end, SpaceX dispatched the “autonomous spaceport drone ship” sailing at sea towards a point where Musk hopes it will serve as an ocean going landing platform for the precision landing of his firm’s Falcon 9 rocket after it concludes its launch phase to the ISS.

The “autonomous spaceport drone ship” departed the port of Jacksonville, FL, on Saturday, Jan. 3, heading to a point somewhere around 200 to 250 miles or so off the US East coast in a northeasterly direction coinciding with the flight path of the rocket.

However, the absolute overriding goal of the mission is to safely deliver NASA’s contracted cargo to the ISS, emphasized Hans Koenigsmann, VP of Mission Assurance, SpaceX, at a media briefing on Jan. 5 at the Kennedy Space Center.

Landing on the off-shore barge is just a secondary objective of SpaceX, not NASA, he repeated several times.

Also loaded onboard are 17 student experiments known collectively as the “Yankee Clipper” mission. The experiments are sponsored by the National Center for Earth and Space Science Education which oversees the Student Spaceflight Experiments Program (SSEP) in partnership with NanoRacks LLC.

They had been selected to fly aboard the Orbital Sciences Cygnus Orb-3 spacecraft bound for the ISS, but were all lost when the rocket exploded unexpectedly after launch from NASA Wallops, VA, on Oct. 28, 2014.

The experiments have been reconstituted to fly on the CRS-5 mission.

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.

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.

The weather forecast stands at 80% GO for favorable conditions at launch time.

NASA Television live launch coverage begins at 3:30 a.m. EST on Jan. 10 at: http://www.nasa.gov/multimedia/nasatv/

SpaceX also will webcast the launch at: http://www.spacex.com/webcast/

Gallery: Spacesuits Are Amazing Human-Protection Machines

Did you know it’s been nearly 50 years since the first spacewalk? On March 18, 1965, Russian Alexei Leonov ventured from the safety of his Russian spacecraft for the first attempt for a person to survive “outside” in a spacesuit. While Leonov had troubles returning to the spacecraft, his brave effort set off a new era of spaceflight. It showed us it was possible for people to work in small spacesuits in space.

Think about what spacewalks have helped us accomplish since then. We’ve walked on the Moon. Constructed the International Space Station. Retrieved satellites. Even flew away from the space shuttle in a jetpack, for a couple of flights in the 1980s.

In this gallery, we’ve highlighted some of the more memorable images from American spacewalks over the years to honor a new Smithsonian Air and Space exhibit opening today (Jan. 8).

Last Minute Scrub for SpaceX Dragon Launch; Try Again Friday for Historic 1st Stage Landing

An actuator that was “behaving strangely” on the SpaceX Falcon 9’s upper stage caused a last minute scrub for Tuesday’s attempt to launch a Dragon capsule to the International Space Station, as well as the first try at an historic first stage landing on a floating platform in the Atlantic Ocean.

Need to investigate the upper stage Z actuator. Was behaving strangely. Next launch attempt on Friday at 5am.

— Elon Musk (@elonmusk) January 6, 2015

SpaceX will try again on Friday, January 9, 2014 at 5:09 a.m. EST. Like today’s attempt, there will be only an instantaneous launch window available, meaning that the blastoff must proceed at that exact instant. Any delays due to technical issues or weather would force further delays.

This is the commercial space company’s fifth resupply mission to the ISS and the unmanned cargo freighter is loaded with more than 5,108 pounds (2317 kg) of scientific experiments, technology demonstrations, crew supplies, spare parts, food, water, clothing and assorted research gear for the space station.

The “experiment” that has attracted the most attention, however, is the attempt to land the first stage of the two-stage rocket on a floating platform in the Atlantic Ocean, approximately 320 km (200 miles) off the coast of Florida.

This is the first attempt at such a landing. SpaceX has conducted numerous successful soft landing tests on land, and done several touchdowns on the ocean’s surface.

Elon Musk has estimated the odds of success at the landing attempt at about 50% at best.

“It’s an experiment,” said Hans Koenigsmann, VP of Mission Assurance at SpaceX, speaking at a media briefing on Jan. 5 at the Kennedy Space Center. “There’s a certain likelihood that this will not work out right, that something will go wrong.” He also added that the landing on the off shore barge is just a secondary objective of SpaceX, not NASA.

Many analysts say a successful landing maneuver would mark a significant step toward making rockets more reusable, which would help cut costs. But others caution that even if this first attempt is successful, we shouldn’t expect to see regular airline-like reuse and large cost drops anytime soon.
