Dragon Launches Successfully, But Suffers Anomaly After Reaching Orbit

Just after 10 am Eastern time, the SpaceX successfully launched their Dragon capsule on a second resupply mission to the International Space Station. The launch, rocket stage and spacecraft separations went perfectly, but the Dragon experienced an anomaly at about the time the solar arrays should have deployed. The SpaceX webcast announced that the spacecraft experienced a problem and then ended the webcast. NASA TV has not offered information either. We’ll provide more information as soon it becomes available.

Update: (10:44 EST) Elon Musk, SpaceX CEO just tweeted: “Issue with Dragon thruster pods. System inhibiting 3 of 4 from initializing. About to inhibit override.” Then minutes later he added, “Holding on solar array deployment until at least two thruster pods are active.”

See below for a continuation of our live-blogging of the Dragon anomaly, as it happened..

Also, here’s the launch video from launch to separation (note, the separation video is spectacular!):

Dragon carries 18 Draco thrusters for attitude control and maneuvering, so there may be an issue with those. Dragon’s thruster problem may be preventing the spacecraft from going into array deploy attitude, thus preventing array deploy.

Only time will tell if this is a software or hardware problem. The SpaceX press kit describes what needs to happen for solar array deploy:

Dragon separates from Falcon 9’s second stage, and seconds later, Dragon will reach its preliminary orbit. It then deploys its solar arrays and begins a carefully choreographed series of Draco thruster firings to reach the space station.

If Dragon can’t make it to the ISS, then it would need to be decided if and how it can return back to Earth on a good trajectory with limited thruster control.

The SpaceX controllers are obviously working to try and resolve the problem.

Update: 11:10 EST An update from NASA TV at about 11:10 am, said that part of response to problem with Dragon may be reorganizing the burn sequences in order for the spacecraft to be able to approach to the ISS. Musk just tweeted: “About to pass over Australia ground station and command inhibit override.”

Update: 11:25 EST: A statement from SpaceX says that “One thruster pod is running. Two are preferred to take the next step which is to deploy the solar arrays. We are working to bring up the other two in order to plan the next series of burns to get to station.”

Update: 11:42 EST: Elon Musk just tweeted: “Thruster pod 3 tank pressure trending positive. Preparing to deploy solar arrays.” That is good news.

Update: 11:50 EST: Another Tweet from Musk, with some short but sweet news: “Solar array deployment successful” That means they were abe to get at least two of the four thruster pods working, per the minimum requirement. Now, to see if the thruster problem causes any issues with getting to the ISS.

Update: 12:05 EST: Elon Musk continues to be the best source of info. He’s just tweeted, “Attempting bring up of thruster pods 2 and 4.”
We’re assuming that means 1 and 3 are already working, since it was going to take at least 2 pods thrusting to enable solar array deploy.

Update: 12:14 EST: The latest statement from SpaceX : “After Dragon achieved orbit, the spacecraft experienced an issue with a propellant valve. One thruster pod is running. We are trying to bring up the remaining three. We did go ahead and get the solar arrays deployed. Once we get at least 2 pods running, we will begin a series of burns to get to station.”

So, they were able to deploy the arrays with just one thruster pod working, and they are now working to get at least one more working. One question to consider is if the spacecraft and arrays were able to be in the right position to gather sunlight and produce power.

Update: 12:42 EST: According to reports on Twitter, a NASA official has said that three Dragon thruster pods are needed to fly to the ISS, and at this point, only one pod is working.

Update: 2:00 EST: This update from SpaceX: “SpaceX is still working through issues in Dragon’s propulsion system. The mission’s first rendezvous burn was delayed at least one orbit to about 2 p.m. EST.” (which is now)….stay tuned for updates. There will be a press conference sometime today, NASA has said, but has not yet set a specific time.

Update: 2:28 EST: NASA says the Dragon capsule Dragon will no longer be able to make its scheduled rendezvous with the station tomorrow. SpaceX indicated the rendezvous with the ISS will now not happen until at least Sunday morning. There will be a news briefing at 3pm EST.

Communication between the ISS crew and mission control confirms the delay for the rendezvous: “They are making progress recovering their prop system, but it’s not going to be in time to support the rendezvous and capture for tomorrow,” NASA’s spacecraft communicator told the crew. “So that is not going to happen tomorrow.”

“OK, copy, sounds like another off-duty day for us,” said ISS commander Kevin Ford. “We don’t wish that. We wish it gets fixed and gets up here to us. That’s really awesome they’re working their way through the problems. That’s what it’s all about.”

Update: 2:58 EST: Latest Tweet from Elon Musk has good news: “Pods 1 and 4 now online and thrusters engaged. Dragon transitioned from free drift to active control. Yes!!”

Update: 4:11 EST: Here’s a brief synopsis of the press briefing:

During the press conference, Elon Musk indicated there was a blockage in the helium line leading to the oxidizer pressurization system, or perhaps a stuck valve, and the pressure was not high enough to turn on the thrusters. The engineering team cycled the valves several times, using pressure hammering to loosen up and debris that might be stuck in the valves. And now, the pressure is nominal, with all the oxidizer tanks holding the target pressure on all 4 pods, and so Musk said he is hopeful that all the thrusters will be able to work.

Musk said they decided to deploy Dragon arrays before two thrusters were online because the temperature of the array actuators was dropping rapidly. But they also deployed solar arrays partly to mitigate Dragon’s attitude rotation “like a skater extending arms during a spin,” he said.

Musk mentioned the batteries on board had 12-14 hours of life, so deploying the arrays early was not a question of running out of power, but making sure solar arrays didn’t get so cold that they couldn’t deploy later.

NASA’s Mike Suffredini said that at least 3 of the 4 pods have to be operational in order to make an approach to the ISS.

They will make a decision on when to make the rendezvous when they’ve ascertained if the thrusters are working.

Ken Kremer will provide a more detailed update later.

The Dragon is carrying 544 kilograms (1,200 lbs) of scientific experiments and supplies to the space station, and docking was scheduled for Saturday at 6:30 a.m. ET (1100 GMT). That will likely change.

Dragon’s 18 Draco thrusters permit orbital maneuvering and attitude control. They are mounted on four pods: two of the pods contain five thrusters and the other two contain four thrusters. They are powered by nitrogen tetroxide/monomethylhydrazine, and the thrust is used to control the approach to the ISS, power departure from the ISS, and control Dragon’s attitude upon reentry.

As far as the solar arrays, each array is constructed of four panels. Each array measures 6.4 meters (21 feet). The arrays can draw up to 5,000 watts of power, which is about enough power to light about 85 light bulbs. For launch, the arrays are stowed in the unpressurized trunk of the Dragon and are covered by protective fairings. When the fairings jettison, the automated deployment of the arrays is triggered. On the way back to Earth the trunk is jettison and it, along with the arrays, burn up in the atmosphere.

If the arrays do not deploy, battery life on Dragon is ~~only a few hours~~ 12-14 hours, which would not be enough time to keep it alive until it would reach the ISS. It will be about 20 hours from launch until it approaches the ISS, if the mission continues on its scheduled timeline.

You may recall that during the previous mission to the ISS in October 2012 (the second flight to ISS, but first operational SpaceX resupply flight) one of the rocket’s first stage engines suffered an anomaly, where a combustion chamber ruptured. That engine was shut down, and the other engines fired longer to make up for it. The Dragon cargo made it to the correct orbit and continued on the ISS, but a satellite that was launched to orbit as a secondary payload by the Falcon 9 rocket was sent into the wrong orbit as a result of “a pre-imposed safety check required by NASA,” on October 7, and the ORBCOMM OG2 satellite later deorbited and fell back to Earth.

For this launch, all nine engines appeared to work nominally and all stages separated perfectly.

But obviously the SpaceX team saw the thruster problem immediately, as that’s when the webcast was ended.

SpaceX Commercial Rocket Poised for March 1 Blast Off to ISS

Kennedy Space Center – All systems are GO and the weather outlook looks spectacular for the March 1 blast off of the privately developed SpaceX Falcon 9 rocket to the International Space Station (ISS).

The Falcon 9 is slated to lift off at 10:10 AM EST with a Dragon capsule loaded with fresh supplies and science gear to continued full up operation and utilization of the ISS.

Right now the weather forecast is at 80% GO on March 1 – with superbly beautiful, clear blue skies here in sunny and comfortably warm Florida from Space Launch Complex 40 at Cape Canaveral Air Force Station.

Large crowds of eager tourists, sightseers and space enthusiasts are already gathering in local hotels – most are sold out including at my hotel where I have been holding well attended ISS star parties during excellent evening viewing opportunities this week.

NASA TV will provide live launch coverage starting at 8 30 AM. SpaceX will also provide a separate feed starting about 40 minutes prior to launch.

The two stage Falcon 9 rocket was rolled out horizontally to the pad late this afternoon (Thursday, Feb. 28) in anticipation of a Friday morning launch. Myself and Dave Dickinson are on-site for Universe Today

The mission dubbed CRS-2 will be only the 2nd commercial resupply mission ever to the ISS.

There are no technical concerns at this time. Saturday March 2 is the back-up launch date in case of a last second scrub. Weather is projected as 80% favorable.

SpaceX President Gwynne Shotwell and NASA officials told me that additional launch opportunities are available Sunday, Monday and Tuesday, if needed, and later until about March 11. After that, the launch team would have to stand down to make way for the next eventual departure of a docked Soyuz and launch of a manned Russian Soyuz capsule with a new three man crew.

The SpaceX Dragon capsule is carrying about 1,200 pounds of vital supplies and research experiments for the six man international crew living aboard the million pound orbiting outpost.

SpaceX is under contract to NASA to deliver over 44,000 pounds of cargo to the ISS during a dozen flights over the next few years at a cost of about $1.6 Billion.

The capsule is fully loaded Shotwell told me. An upgraded Falcon 9 will be used in the next launch that will allow for a significant increase in the cargo up mass, Shotwell elaborated.

The Dragon is due to dock with the ISS in record time some 20 hours after blast off.

Wouldn’t you love to wake up to this gorgeous view of our home planet as a big hand waves a friendly good morning ?!

Well, having survived high speed wayward Asteroids and Meteors these past few days, the human crew circling Earth aboard the International Space Station (ISS) is game to snatch a flying Space Dragon before too long.

NASA will dispatch astronaut fun to orbit in the form of the privately built SpaceX Dragon in a tad less than two weeks time that the crew will ensnare with that robotic hand from Canada and join to the ISS.

On March 1 at 10:10 AM EST, a Space Exploration Technologies (SpaceX) Falcon 9 rocket is slated to blast off topped by the Dragon cargo vehicle on what will be only the 2nd commercial resupply mission ever to the ISS.

The flight, dubbed CRS-2, will lift off from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida carrying about 1,200 pounds of vital supplies and science experiments for the six man international crew living aboard the million pound orbiting outpost.

The ISS would plummet from the sky like a flaming, exploding meteor and disintegrate without periodic and critical cargo and fueling resupply flights from the ISS partner nations.

There will be some heightened anticipation for the March 1 SpaceX launch following the premature shutdown of a 1st stage Merlin engine during the last Falcon 9 launch in 2012.

The solar powered Dragon capsule will rendezvous with the ISS a day later on March 2, when NASA astronauts Kevin Ford and Tom Marshburn will reach out with the Canadian built robotic marvel, grab the Dragon by the proverbial “tail” and attach it to the Earth-facing port of the station’s Harmony module.

The Dragon will remain docked to the ISS for about three weeks while the crew unloads all manner of supplies including food, water, clothing, spare parts and gear and new science experiments.

Then the astronauts will replace all that cargo load with numerous critical experiment samples they have stored during ongoing research activities, as well as no longer needed equipment and trash totaling about 2300 pounds, for the return trip to Earth and a Pacific Ocean splashdown set for March 25 – as things stand now.

SpaceX is under contract to NASA to deliver about 44,000 pounds of cargo to the ISS during a dozen flights over the next few years at a cost of about $1.6 Billion.

SpaceX comprises one half of NASA’s Commercial Resupply Services program to replace the cargo up mass capability the US lost following the retirement of NASA’s space shuttle orbiters in 2011.

SpaceX also won a NASA contract to develop a manned version of the Dragon capsule and aims for the first crewed test flight in about 2 to 3 years – sometime during 2015 depending on the funding available from NASA.

The US is now totally dependent on the Russians to loft American astronauts to the ISS on their Soyuz capsules for at least the next 3 to 5 years directly as a result of the shuttle shutdown.

Along with SpaceX, Orbital Sciences Corp also won a $1.9 Billion cargo resupply contract from NASA to deliver some 44,000 pounds of cargo to the ISS using the firm’s new Antares rocket and Cygnus capsule – launching 8 times from a newly constructed pad at NASA’s Wallops Island Facility in Virginia.

The maiden launch of Orbital’s Antares/Cygnus system has repeatedly been delayed – like SpaceX before them.

NASA hopes the first Antares/Cygnus demonstration test flight will now occur in March or April. However, the Antares 1st stage hot fire test scheduled for earlier this week on Feb. 13 had to be aborted at the last second due to a technical glitch caused by a low nitrogen purge pressurization.

For the SpaceX launch, NASA has invited 50 lucky social media users to apply for credentials for the March 1 launch

Watch for my upcoming SpaceX launch reports from the Kennedy Space Center and SpaceX launch facilities.

Antares Rocket Critical Hotfire Engine Test Set for Feb. 12

Orbital Sciences Corporation has at last scheduled a critical engine test for the firm’s new commercially developed Antares medium class rocket for Feb. 12 at the Mid-Atlantic Regional Spaceport’s (MARS) Pad-0A.

NASA’s Wallops Flight Facility will provide launch range support for the Antares rocket test which is a key milestone on the path to a flight that is crucial for eventual resupply of the International Space Station (ISS).

The window for the 29 second long engine test is 6-9 p.m EST. There will be no live broadcast or formal viewing of the test since it is only operational in nature.

For this hot fire test only the first stage of the Antares rocket will be rolled out to the launch pad – the first of its kind constructed in America in several decades.

During the test, the Antares’ dual AJ26 first stage rocket engines will generate a combined total thrust of 680,000 lbs. In a unique capability for its duration, the rocket will be held down on the pad and accounts for the huge water tower built nearby.

The goal of the hot fire test is a complete checkout of the rocket’s first stage and all the support systems at Pad-0A being utilized for the first time.

Antares is the launcher for Orbital’s unmanned commercial Cygnus cargo spacecraft that NASA’s hopes will further reestablish American resupply missions to the International Space Station (ISS) lost with the shuttle’s shutdown.

If successful, a full up test flight of the 131 foot tall Antares with a Cygnus mass simulator bolted on top is planned for the maiden launch in roughly 4 to 6 weeks later, perhaps by late March 2013.

Antares/Cygnus will provide a similar service to the Falcon 9/Dragon system developed by SpaceX Corporation – which has already docked twice to the ISS during historic linkups in 2012.

Both the Orbital and SpaceX systems were developed under NASA’s Commercial Orbital Transportation Services (COTS) program to replace the ISS cargo capability previously tasked to NASA Space Shuttle’s.

A docking demonstration mission to the ISS would follow later in 2013 which would be nearly identical in scope to the SpaceX Falcon 9/Dragon demonstration flight successfully accomplished in May 2012.

The Antares first stage is powered by a pair of Soviet era NK-33 engines built during the 1960 and 1970’s as part of Russia’s ill-fated N-1 manned moon program. The engines have since been upgraded and requalified by Aerojet Corp. and integrated into the Ukrainian built first stage rocket as AJ-26 engines.

Tens of millions of US East Coast residents in the Mid-Atlantic and Northeast regions have never seen anything as powerful as an Antares rocket launch in their neighborhood.

“Antares is the biggest rocket ever launched from Wallops,” NASA Wallops spokesman Keith Koehler told me.

Private Test Pilots to Fly 1st Commercial Crewed Space Flights for NASA

Dream Chaser from Sierra Nevada docks at ISS

[/caption]

Image Caption: Dream Chaser commercial crew vehicle built by Sierra Nevada Corp docks at ISS

Commercial test pilots, not NASA astronauts, will fly the first crewed missions that NASA hopes will at last restore America’s capability to blast humans to Earth orbit from American soil – perhaps as early as 2015 – which was totally lost following the forced shuttle shutdown.

At a news briefing this week, NASA managers at the Kennedy Space Center (KSC) said the agency is implementing a new way of doing business in human spaceflight and purposely wants private companies to assume the flight risk first with their crews before exposing NASA crews as a revolutionary new flight requirement. Both NASA and the companies strongly emphasized that there will be no shortcuts to flying safe.

A trio of American aerospace firms – Boeing, SpaceX and Sierra Nevada Corp – are leading the charge to develop and launch the new commercially built human-rated spacecraft that will launch Americans to LEO atop American rockets from American bases.

The goal is to ensure the nation has safe, reliable and affordable crew transportation systems for low-Earth orbit (LEO) and International Space Station (ISS) missions around the middle of this decade.

The test launch schedule hinges completely on scarce Federal dollars from NASA for which there is no guarantee in the current tough fiscal environment.

The three companies are working with NASA in a public-private partnership using a combination of NASA seed money and company funds. Each company was awarded contracts under NASA’s Commercial Crew Integrated Capability Initiative, or CCiCap, program, the third in a series of contracts aimed at kick starting the development of the so-called private sector ‘space taxis’ to fly astronauts to and from the ISS.

Caption: Boeing CST-100 crew vehicle docks at the ISS

The combined value of NASA’s Phase 1 CCiCap contracts is about $1.1 Billion and runs through March 2014 said Ed Mango, NASA’s Commercial Crew Program manager. Phase 2 contract awards will follow and eventually lead to the actual flight units after a down selection to one or more of the companies, depending on NASA’s approved budget.

Since the premature retirement of NASA’s shuttle fleet in 2011, US astronauts have been 100% reliant on the Russians to hitch a ride to the ISS – at a price tag of over $60 Million per seat. This is taking place while American aerospace workers sit on the unemployment line and American expertise and billions of dollars of hi-tech space hardware rots away or sits idly by with each passing day.

Boeing, SpaceX and Sierra Nevada Corp seek to go where no private company has gone before – to low Earth orbit with their private sector manned spacecraft. And representatives from all three told reporters they are all eager to move forward.

All three commercial vehicles – the Boeing CST-100; SpaceX Dragon and Sierra Nevada Dream Chaser – are designed to carry a crew of up to 7 astronauts and remain docked at the ISS for more than 6 months.

“For well over a year now, since Atlantis [flew the last space shuttle mission], the United States of America no longer has the capability to launch people into space. And that’s something that we are not happy about,” said Garrett Reisman, a former space shuttle astronaut who is now the SpaceX Commercial Crew project manager leading their development effort. “We’re very proud to be part of the group that’s going to do something about that and get Americans back into space.”

“We are the emotional successors to the shuttle,” said Mark Sirangelo, Sierra Nevada Corp. vice president and SNC Space Systems chairman. “Our target was to repatriate that industry back to the United States, and that’s what we’re doing.”

Sierra Nevada is developing the winged Dream Chaser, a mini-shuttle that launches atop an Atlas V rocket and lands on a runway like the shuttle. Boeing and SpaceX are building capsules that will launch atop Atlas V and Falcon 9 rockets, respectively, and then land by parachute like the Russian Soyuz capsule.

SpaceX appears to be leading the pack using a man-rated version of their Dragon capsule which has already docked twice to the ISS on critical cargo delivery missions during 2012. From the start, the SpaceX Dragon was built to meet the specification ratings requirements for a human crew.

Reisman said the first manned Dragon test flight with SpaceX test pilots could be launched in mid 2015. A flight to the ISS could take place by late 2015. Leading up to that in April 2014, SpaceX is planning to carry out an unmanned in-flight abort test to simulate and test a worst case scenario “at the worst possible moment.”

Boeing is aiming for an initial three day orbital test flight of their CST-100 capsule during 2016, said John Mulholland, the Boeing Commercial Programs Space Exploration vice president and program manager. Mulholland added that Chris Ferguson, the commander of the final shuttle flight by Atlantis, is leading the flight test effort.

Boeing has leased one of NASA’s Orbiter Processing Facility hangers (OPF-3) at KSC. Mulholland told me that Boeing will ‘cut metal’ soon. “Our first piece of flight design hardware will be delivered to KSC and OPF-3 within 5 months.”

Sierra Nevada plans to start atmospheric drop tests of an engineering test article of the Dream Chaser from a carrier aircraft in the next few months in an autonomous mode. The test article is a full sized vehicle.

“It’s not outfitted for orbital flight; it is outfitted for atmospheric flight tests,” Sirangelo told me. “The best analogy is it’s very similar to what NASA did in the shuttle program with the Enterprise, creating a vehicle that would allow it to do significant flights whose design then would filter into the final vehicle for orbital flight.”

Now to the issue of using commercial space test pilots in place of NASA astronauts on the initial test flights.

At the briefing, Reisman stated, “We were told that because this would be part of the development and prior to final certification that we were not allowed, legally, to use NASA astronauts to be part of that test pilot crew.”

So I asked NASA’s Ed Mango, “Why are NASA astronauts not allowed on the initial commercial test flights?”

Mango replied that NASA wants to implement the model adopted by the military wherein the commercial company assumes the initial risk before handing the airplanes to the government.

“We would like them to get to a point where they’re ready to put their crew on their vehicle at their risk,” said Mango. “And so it changes the dynamic a little bit. Normally under a contract, the contractor comes forward and says he’s ready to go fly but it’s a NASA individual that’s going to sit on the rocket, so it becomes a NASA risk.

“What we did is we flipped it around under iCAP. It’s not what we’re going to do long term under phase two, but we flipped it around under iCAP and said we want to know when you’re ready to fly your crew and put your people at risk. And that then becomes something that we’re able to evaluate.”

“In the end all our partners want to fly safe. They’re not going to take any shortcuts on flying safe,” he elaborated. “All of us have the same initiative and it doesn’t matter who’s sitting on top of the vehicle. It’s a person, and that person needs to fly safely and get back home to their families. That’s the mission of all our folks and our partners – to go back home and see their family.”

Given the nations fiscal difficulties and lack of bipartisan cooperation there is no guarantee that NASA will receive the budget it needs to keep the commercial crew program on track.

Indeed, the Obama Administrations budget request for commercial crew has been repeatedly slashed by the US Congress to only half the request in the past two years. These huge funding cuts have already forced a multi-year delay in the inaugural test flights and increased the time span that the US has no choice but to pay Russia to launch US astronauts to the ISS.

“The budget is going to be an extremely challenging topic, not only for this program but for all NASA programs,” said Phil McAlister, NASA Commercial Spaceflight Development director.

NASA is pursuing a dual track approach in reviving NASA’s human spaceflight program. The much larger Orion crew capsule is simultaneously being developed to launch atop the new SLS super rocket and carry astronauts back to the Moon by 2021 and then farther into deep space to Asteroids and one day hopefully Mars.

SpaceX Grasshopper Takes Off and Lands Vertically in New 12-Story Hop

SpaceX recently released video of the latest test of their Grasshopper Vertical Take Off and Landing Vehicle, where it rose 40 meters (131 feet), hovered and landed safely on the pad using closed loop thrust vector and throttle control.

The test flight took place on December 17, 2012 at SpaceX’s rocket development facility in McGregor, Texas. The goal of Grasshopper is to eventually create a reusable first stage for SpaceX’s Falcon 9 rocket, which would be able to land safely instead of falling back into the ocean and not being usable again.

SpaceX CEO Elon Musk Tweeted that they strapped a 6-ft (2 meter) cowboy dummy to the side of the rocket “to provide a little perspective on the size of Grasshopper.”

See the pictures below:

SpaceX said the total test duration was 29 seconds. Grasshopper stands 10 stories tall and consists of a Falcon 9 rocket first stage, Merlin 1D engine, four steel landing legs with hydraulic dampers, and a steel support structure.

Timelapse: Dragon’s Departure from the ISS

This video shows various views of the Dragon capsule being unberthed and moving away from the International Space Station, and is sped up at 15 times actual speed. The kicker comes at the end with a look back at the ISS. Not quite as good a view as the old space shuttle flyarounds, but nice to see the station as a whole.

Desert RATS Begin Simulated Asteroid Mission Today

Conspiracy theories abound that the Apollo landings all took place on a film set in California, but today NASA’s Desert RATS team begins a mission to asteroid Itokawa. They will land, rove and even undertake spacewalks, without ever stepping foot out of their home base at Johnson Space Center in Texas. This is no hoax however, but a simulated mission to test out NASA’s audacious plan to send astronauts to an asteroid by 2025.

The Desert RATS have been testing robots and other tools that could be used on future exploration missions since 1997, (this is their 15th mission) usually doing analog missions out in the field. “Desert” refers to the Arizona desert, where a lot of the team’s activities take place and “RATS” stands for “Research and Technology Studies.”

However, since they are now testing out a zero-G visit to an asteroid, the team will use mockups inside JSC’s Space Vehicle Mockup Facility, which offers a medley of tools and simulators that would be difficult to transport to a field test location.

For example, the Multi-Mission Space Exploration Vehicle (MMSEV) is designed to both rove across a planetary surface on a wheeled chassis or fly in space using advanced propulsion systems. Four crew members will take it in turns to live in and operate the simulator to explore the asteroid.

The MMSEV can be put on a sled on an air-bearing floor to simulate the moves that the crew might feel during a real mission. There will also be a 50-second delay in voice transmission, going each way to simulate the light-speed travel time between Earth and the asteroid.

The crew can also undertake spacewalks using ARGOS (Active Response Gravity Offload System) an overhead gantry crane system that simulates the reduced gravity environment. In reality nothing would stop astronauts from just floating off the surface but NASA is thinking about using jetpacks, tethers, bungees, nets or spiderwebs to allow them to float just above the surface attached to a smaller mini-spaceship.

A team of scientists from the Astromaterials Research and Exploration Science Directorate will ensure proper scientific methods are applied to asteroid sample collection techniques throughout the 10 day mission.

The mission is slated to run until August 30th or 31st. Find out more here or follow the NASA Desert RATS team on Twitter

Historic SpaceX Dragon Docking to ISS – Highlights Video

SpaceX has released a cool video (above) recapping the mission highlights of the historic May 22 blastoff of the firm’s Falcon 9 rocket with the Dragon spacecraft that went on to become the first privately developed vehicle in history to successfully dock to the International Space Station (ISS) on May 25, 2012.

Dragon was captured with a robotic arm operated by astronauts Don Pettit and Andre Kuipers working in tandem aboard the ISS as it approached the massive orbiting lab complex and was then berthed at an Earth facing port.

Dragon was the first US spacecraft to attach to the ISS since the retirement of NASA’s Space Shuttle program last July 2011 following the STS-135 mission of shuttle Atlantis. The 14.4 ft (4.4 meter) long resupply vehicle delivered over 1000 pounds of non-critical gear, food, clothing and science equipment to the ISS.

After spending six days at the ISS, the Dragon undocked and splashed down in the Pacific Ocean some 560 miles off the coast of California on May 31, 2012.

The Falcon 9 rocket and Dragon cargo carrier were designed, developed and built by Hawthorne, Calif., based SpaceX Corporation, founded in 2002 by CEO and Chief Designer Elon Musk.

SpaceX signed a contract with NASA in 2006 to conduct twelve Falcon 9/Dragon resupply missions to carry about 44,000 pounds of cargo to the ISS at a cost of some $1.6 Billion over the next few years. The first operational Dragon CRS mission is slated to blast off around October 2012.
