Imagine that you were in the middle of a module on the International Space Station. Floating in mid-air, far from handholds or any way to propel yourself. Is there any way to get out of that situation?
The short answer is not easily, and the longer answer is it could be an effective way to trap criminals in space, joked veteran cosmonaut Maxim Suraev in a press conference today (March 18) for the upcoming Expedition 40/41 mission, which also includes rookies Alex Gerst and Reid Wiseman.
Speaking in Russian, Suraev explained that during his last 2010 mission, he had crew members set him up in the middle of the station’s Node 3. “It is true that you can twist as much as a contortionist, but you won’t be able to move because you have nothing to bear against,” he said in remarks translated into English.
That said, the ventilation system on station does tend to push objects (and people) towards the vents after a time, he observed. What if you had multiple vents set up, however?
“I thought that if ever we have a permanent human habitation in space, this would be the best way to keep a person confined — like in a prison — in the middle of the room, where he or she could not move anywhere,” Suraev continued. “Being in limbo, as you will. The only thing that is required is a large room, a person and several fans blowing in different directions to keep the person in the middle of the room. That’s scary, trust me!”

There’s no fear on Suraev’s part that it will happen with his crewmates, however. “My new crew, they’re really good guys and I’m really looking forward to being with my new crew in space, and to spend five and a half months aboard the space station,” he said in an English phone interview after the press conference. (Good news given that Suraev will assume command of Expedition 41.)
The crew (who lifts off in May) will have an action-packed mission. It will include the arrival of the last Automated Transfer Vehicle (ATV) and — if NASA fixes on a spacesuit leak allow — two American maintenance spacewalks. There also are 162 experiments to perform (this according to Gerst) and if there’s time, checking out our home planet.
“Earth observation was not one of the primary goals that [station] was designed for,” he cautioned in a phone interview, but he added that one of its strengths is there are people on board the orbiting laboratory that can fill in the gaps for other missions.
Gerst (who was a volcano researcher before becoming an astronaut) pointed out that if a volcano erupts, a typical Earth satellite would look straight down at it. Astronauts can swing around in the Cupola and get different views quickly, which could allow scientists to measure things such as the volcano plume height.
Another example of flexibility: The Expedition 39 crew right now is (news reports say) helping out with the search for the missing Malaysian Airline Flight 370.
“We’re really good at capturing things quickly and then sending the pictures down to the ground,” Gerst said.
Wiseman, as one of the rookies on mission, says he is interested in comparing the experience to his multi-month Navy missions at sea. It’s all a matter of mindset, he said in a phone interview. He once was assigned to a naval voyage that was expected to be at sea for six months. Then they were instructed it would be 10 months, leading to fistfights and other problems on board, he recalled.

Astronauts for the forthcoming one-year mission to station, he pointed out, will launch with different expectations than someone expecting about a six-month stay. “If you know you’re up there for one year, you’re going to pace yourself for one year,” he said.
But there still will be sacrifices, as Wiseman has two daughters (five years old and eight years old). He’s asking the older child to do a bit of social media, and the younger one to draw pictures that could be included in the “care packages” astronauts receive from Earth. “It’s going to be tough not to see them on a daily basis. They grow so fast,” he said.
Other things to watch for on this mission include the arrival of the station’s first 3-D printer, setup of an alloy furnace to make new materials in microgravity, and a potential Wiseman-led “come out and wave campaign” that would encourage families to go outside and tweet about the space station as they watch it.

Legs — yes, legs — are on the manifest for the next SpaceX Dragon flight. The commercial spacecraft is expected to blast off March 16 with appendenges for Robonaut 2 on board, allowing the humanoid to move freely around station. After some initial tests in June will come R2’s first step, marking a new era in human spaceflight.
What’s exciting about R2 is not only its ability to take over simple tasks for the astronauts in station, but in the long run, to head “outside” to do spacewalks. This would greatly reduce risk to the astronauts, as extravehicular activity is one of the most dangerous things you can do outside (as a spacesuit leak recently reminded us.)
When installed, Robonaut will have a “fully extended leg span” of nine feet (wouldn’t we love to see the splits with that). Instead of a foot, each seven-jointed leg will have an “end effector” that is a sort of clamp that can grab on to things for a grip. It’s similar to the technology used on the Canadarm robotic arm, and also like Canadarm, there will be a vision system so that controllers know where to grasp.

The robot first arrived on station in February 2011 and (mostly while tied down) has done a roster of activities, such as shake hands with astronaut Dan Burbank in 2012 (a humanoid-human first in space), say hello to the world with sign language, and do functions such as turn knobs and flip switches. During Expedition 34/35 in 2012-13, astronaut Tom Marshburn even made Robonaut 2 catch a free-floating object through teleoperation.
Eventually NASA expects to use the robot outside the station, but more upgrades to Robonaut 2’s upper body will be needed first. The robot could then be used as a supplement to spacewalks, which are one of the most dangerous activities that humans do in space.
Closer to Earth, NASA says the technology has applications for items such as exoskeletons being developed to help people with physical disabilities.

SpaceX is nearly ready to Rock ‘n’ Roll with their first rocket sporting landing legs and slated to blast off this coming weekend carrying a commercial Dragon cargo freighter bound for the International Space Station (ISS).
Check out the Falcon 9 rockets gorgeous legs unveiled today by SpaceX in an eye popping new photo featured above.
The newly released image shows the private Falcon 9 positioned horizontally inside the Cape Canaveral processing hanger and looking up directly from the bottom of her legs and nine powerful first stage engines.
Following a brief static hotfire test this past weekend of all nine upgraded Merlin 1D engines powering the first stage of SpaceX’s next generation Falcon 9 rocket, the path is clear for Sunday’s (March 16) night time lift off at 4:41 a.m. EDT from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.
This week, engineers working inside the hanger are loading the Dragon vessel with the final cargo items bound for the station that are time sensitive.

Altogether, this unmanned SpaceX CRS-3 mission will deliver over 5000 pounds of science experiments and essential gear, spare parts, crew provisions, food, clothing and supplies to the six person crews living and working aboard the ISS soaring in low Earth orbit under NASA’s Commercial Resupply Services (CRS) contract.

Dragon is carrying research cargo and equipment for over 150 science investigations, including 100 protein crystal experiments that will allow scientists to observe the growth of crystals in zero-G.
Conducted in the absence of gravity, these space experiments will help Earth bound researchers to potentially learn how to grow crystals of much larger sizes compared to here on Earth and afford scientists new insights into designing and developing new drugs and pesticides.
A batch of new student science experiments are also packed aboard and others will be returned at the end of the mission.
The attachment of landing legs to the first stage of SpaceX’s next-generation Falcon 9 rocket counts as a major first step towards the firm’s future goal of building a fully reusable rocket.
For this Falcon 9 flight, the rocket will sprout legs for a controlled soft landing in the Atlantic Ocean guided by SpaceX engineers.
“F9 will continue to land in the ocean until we prove precision control from hypersonic thru subsonic regimes,” says SpaceX CEO and founder Elon Musk.
It will be left to a future mission to accomplish a successful first stage touchdown by the landing legs on solid ground back at Cape Canaveral, Florida.
Much development works remains before a land landing will be attempted.
The Falcon will roll out from the hanger to Launch Pad 40 on Saturday, March 15.

SpaceX is under contract to NASA to deliver 20,000 kg (44,000 pounds) of cargo to the ISS during a dozen Dragon cargo spacecraft flights over the next few years at a cost of about $1.6 Billion.
To date SpaceX has completed two operational cargo resupply missions and a test flight to the station. The last flight dubbed CRS-2 blasted off a year ago on March 1, 2013 atop the initial version of the Falcon 9 rocket.

Following the scheduled March 16 launch and a series of orbit raising and course corrections over the next two days, Dragon will rendezvous and dock at the Earth facing port on the station’s Harmony module on March 18.
The Harmony port was recently vacated by the Orbital Sciences built Cygnus cargo spacecraft to make way for Dragon.
This extra powerful new version of the Falcon 9 dubbed v1.1 is powered by a cluster of nine of SpaceX’s new Merlin 1D engines that are about 50% more powerful compared to the standard Merlin 1C engines. The nine Merlin 1D engines 1.3 million pounds of thrust at sea level rises to 1.5 million pounds as the rocket climbs to orbit.
Therefore the upgraded Falcon 9 can boost a much heavier cargo load to the ISS, low Earth orbit, geostationary orbit and beyond.
Indeed Dragon is loaded with about double the cargo weight carried previously.
The Merlin 1D engines are arrayed in an octaweb layout for improved efficiency.

UPDATE: The Expedition 38 crew landed safely at about 11:24 p.m. EDT (3:24 a.m. UTC) on March 11. You can catch the highlights of the crew extraction at this NASA video.
The action starts today around 4:30 p.m. EDT (8:30 p.m. UTC) with the hatch closure ceremony, which you can watch in the video, with landing expected at 11:24 p.m. EDT (3:24 a.m. UTC). We have full details of the schedule below the jump.
Expedition 38’s landing crew includes Russian astronauts Oleg Kotov and Sergey Ryazanskiy, and NASA astronaut Michael Hopkins. Kotov was the one in charge of the station while four spacewalks and hundreds of experiments took place, not to mention visits from three vehicles. This past weekend, he passed the baton to Japanese astronaut Koichi Wakata, making Wakata the first person from his country to assume control of station.
Farewells and hatch closure will start around 4:30 p.m. EDT (8:30 p.m. UTC) on NASA Television, with undocking occurring at 8:02 p.m. EDT (12:02 a.m. UTC.) As usual, the crew will be in a Russian Soyuz spacecraft for the landing, making their way back to an area near Dzhezkazgan, Kazakhstan. The deorbit burn will take place around 10:30 p.m. EDT (2:30 a.m. UTC), and landing at 11:24 p.m. EDT (3:24 a.m. UTC).
We recommend you tune into NASA TV slightly before each of these events, and to expect that the timing might be variable as mission events warrant. NASA’s full schedule (in central time) is at the bottom of this story.

The historic blast off of the first SpaceX rocket equipped with ‘landing legs’ and also carrying a private Dragon cargo vessel bound for the Space Station is now slated for March 16 following a short and “successful” hot fire check test of the first stage engines on Saturday, March 8.
It’s T Minus 1 week to lift off !
The brief two second ignition of all nine upgraded Merlin 1D engines powering the first stage of SpaceX’s next generation, commercial Falcon 9 rocket at the end of a simulated countdown is a key test required to clear the way for next Sunday’s planned night time lift off at 4:41 a.m. EDT from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.
“Falcon 9 and Dragon conducted a successful static fire test in advance of next week’s CRS-3 launch to station!” SpaceX announced today.
The primary goal of the unmanned SpaceX CRS-3 mission is to deliver over 5000 pounds of science experiments, gear and supplies loaded inside Dragon to the six person crew living and working aboard the International Space Station (ISS) flying in low Earth orbit under NASA’s Commercial Resupply Services (CRS) contract.
“In this final major preflight test, Falcon 9’s 9 first-stage engines were ignited for 2 seconds while the vehicle was held down to the pad,” said SpaceX.

The static hot firing is a full up assessment of the rocket, engines, propellant loading and countdown procedures leading to a launch. The engines typically fire for a barely a few seconds.
SpaceX engineers will evaluate the engine firing to ensure all systems are ready for launch.
This commercial Falcon 9 rocket is equipped for the first time with a quartet of landing legs, Elon Musk, the company’s founder and CEO, announced recently as outlined in my story – here.
The attachment of landing legs to the first stage of SpaceX’s next-generation Falcon 9 rocket counts as a major step towards the firm’s future goal of building a fully reusable rocket.
The eventual goal is to accomplish a successful first stage touchdown by the landing legs on solid ground back at Cape Canaveral, Florida.
For this Falcon 9 flight, the rocket will sprout legs for a controlled soft landing in the Atlantic Ocean guided by SpaceX engineers.
Extensive work and testing remains to develop and refine the technology before a land landing will be attempted by the company.
“F9 will continue to land in the ocean until we prove precision control from hypersonic thru subsonic regimes,” Musk says.

SpaceX hopes the incorporation of landing legs will one day lead to cheaper, reusable boosters that can be manufactured at vastly reduced cost.
The March 16 launch will be the fourth overall for the next generation Falcon 9 rocket, but the first one capped with a Dragon and heading to the massive orbital lab complex.

Three prior launches of the more powerful Falcon 9 lofting commercial telecom satellites in September and December 2013 and January 2014 were all successful and paved the way for SpaceX’s new mission to the ISS.
And this Dragon is loaded with the heaviest manifest yet.
The research cargo includes 100 protein crystal experiments that will allow scientists to observe the growth of crystals in zero-G.
In the absence of gravity, the crystals will hopefully grow to much larger sizes than here on Earth and afford scientists new insights into designing and developing new drugs and pesticides.

To date SpaceX has completed two operational cargo resupply missions. The last flight dubbed CRS-2 blasted off a year ago on March 1, 2013 atop the initial version of the Falcon 9 rocket.
If the launch takes place as planned on March 16, Dragon will rendezvous and dock at the Earth facing port on the station’s Harmony module, after a two day orbital chase, on March 18.
Both the Dragon and Cygnus resupply spacecraft were privately developed with seed money from NASA in a public-private partnership in order to restore the cargo up mass capability the US completely lost following the retirement of NASA’s space shuttle orbiters in 2011.
The Dragon docking will take place a few days after Monday’s (March 10) scheduled departure of three crew members aboard a Russian Soyuz capsule.
Watch the Soyuz leave live on NASA TV.
The departure of Russian cosmonauts Oleg Kotov and Sergey Ryazanskiy along with NASA astronauts Mike Hopkins marks the end of Expedition 38 and the beginning of Expedition 39.
It also leaves only a three person crew on board to greet the Dragon.
The Soyuz return to Earth comes amidst the ongoing Crimean crisis as tensions continue to flare between Russian, Ukraine and the West.

Command of the station was passed today from Oleg Kotov to the Japan Aerospace Exploration Agency astronaut Koichi Wakata.
With the start of Expedition 39, Wakata thus becomes the first Japanese astronaut to command the ISS.
Wakata and NASA astronaut Rick Mastracchio with use the stations Canadarm 2 to grapple and berth Dragon to its docking port.
Dragon is due to stay at station for about three weeks until April 17.
Then it will undock and set course for a parachute assisted splash down in the Pacific Ocean off the coast of Baja California.
For the return to Earth, Dragon will be packed with more than 3,500 pounds of highly valuable experiment samples accumulated from the crews onboard research as well as assorted equipment and no longer need items.

Virtually every aspect of the manned and unmanned US space program – including NASA, other government agencies, private aerospace company’s and crucially important US national security payloads – are highly dependent on Russian & Ukrainian rocketry and are therefore potentially at risk amidst the current Crimea crisis as tensions flared up dangerously in recent days between Ukraine and Russia with global repercussions.
The International Space Station (ISS), astronaut rides to space and back, the Atlas V and Antares rockets and even critical U.S. spy satellites providing vital, real time intelligence gathering are among the examples of programs that may be in peril if events deteriorate or worse yet, spin out of control.
The Crimean confrontation and all the threats and counter threats of armed conflicts and economic sanctions shines a spotlight on US vulnerabilities regarding space exploration, private industry and US national security programs, missions, satellites and rockets.
The consequences of escalating tensions could be catastrophic for all sides.
Many Americans are likely unaware of the extent to which the US, Russian and Ukrainian space programs, assets and booster rockets are inextricably intertwined and interdependent.
First, let’s look at America’s dependency on Russia regarding the ISS.
The massive orbiting lab complex is a partnership of 15 nations and five space agencies worldwide – including Russia’s Roscosmos and the US NASA. The station is currently occupied by a six person crew of three Russians, two Americans and one Japanese.
Since the forced retirement of NASA’s space shuttle program in 2011, America completely lost its own human spaceflight capability. So now the only ticket for astronauts to space and back is by way of the Russian Soyuz capsule.

American and station partner astronauts are 100% dependent on Russia’s three seat Soyuz capsule and rocket for rides to the ISS.
Russia has a monopoly on reaching the station because the shuttle was shut down by political ‘leaders’ in Washington, DC before a new U.S. manned space system was brought online.
And congressional budget cutters have repeatedly slashed NASA’s budget, thereby increasing the gap in US manned spaceflight launches from American soil by several years already.
Congress was repeatedly warned of the consequences by NASA and responded with further reductions to NASA’s budget.
In a continuation of the normal crew rotation routines, three current crew members are set to depart the ISS in a Soyuz and descend to Earth on Monday, March 10.
Coincidentally, one of those Russian crew members, Oleg Kotov, was actually born in Crimea when it was part of the former Soviet Union.
A new three man crew of two Russians and one American is set to blast off in their Soyuz capsule from Russia’s launch pad in Kazakhstan on March 25.
The U.S. pays Russia $70 million per Soyuz seat under the most recent contact, while American aerospace workers are unemployed.
The fastest and most cost effective path to restore America’s human spaceflight capability to low Earth orbit and the ISS is through NASA’s Commercial Crew Program (CCP) seeking to develop private ‘space taxis’ with Boeing, SpaceX and Sierra Nevada.
Alas, Congress has sliced NASA’s CCP funding request by about 50% each year and the 1st commercial crew flight to orbit has consequently been postponed by more than three years.
So it won’t be until 2017 at the earliest that NASA can end its total dependence on Russia’s Soyuz.
A sensible policy to eliminate US dependence on Russia would be to accelerate CCP, not cut it to the bone, especially in view of the Crimean crisis which remains unresolved as of this writing.
If U.S. access to Soyuz seats were to be cut off, the implications would be dire and it could mean the end of the ISS.
When NASA Administrator Chales Bolden was asked about contingencies at a briefing yesterday, March 4, he responded that everything is OK for now.
“Right now, everything is normal in our relationship with the Russians,” said Bolden.
“Missions up and down are on target.”
“People lose track of the fact that we have occupied the International Space Station now for 13 consecutive years uninterrupted, and that has been through multiple international crises.”
“I don’t think it’s an insignificant fact that we are starting to see a number of people with the idea that the International Space Station be nominated for the Nobel Peace Prize.”
But he urged Congress to fully fund CCP and avoid still more delays.
“Let me be clear about one thing,” Bolden said.
“The choice here is between fully funding the request to bring space launches back to the US or continuing millions in subsidies to the Russians. It’s that simple. The Obama administration chooses investing in America, and we believe Congress will choose this course as well.”

Now let’s examine a few American rockets which include substantial Russian and Ukrainian components – without which they cannot lift one nanometer off the ground.
The Atlas V rocket developed by United Launch Alliance is the current workhorse of the US expendable rocket fleet.
Coincidentally the next Atlas V due to blastoff on March 25 will carry a top secret spy satellite for the U.S. National Reconnaissance Office (NRO).
The Atlas V first stage however is powered by the Russian built and supplied RD-180 rocket engine.
Several Air Force – DOD satellites are launched on the Atlas V every year.
Many NASA probes also used the Atlas V including Curiosity, MAVEN, Juno and TDRS to name just a few.

What will happen to shipments of the dual nozzle, dual chamber RD-180’s manufactured by Russia’s NPO Energomesh in the event of economic sanctions or worse? It’s anyone’s guess.
ULA also manufactures the Delta IV expendable rocket which is virtually all American made and has successfully launched numerous US national security payloads.
The Antares rocket and Cygnus resupply freighter developed by Orbital Sciences are essential to NASA’s plans to restore US cargo delivery runs to the ISS – another US capability lost by voluntarily stopping shuttle flights. .
Orbital Sciences and SpaceX are both under contract with NASA to deliver 20,000 kg of supplies to the station. And they both have now successfully docked their cargo vehicles – Cygnus and Dragon – to the ISS.
The first stage of Antares is built in Ukraine by the Yuzhnoye Design Bureau and Yuzhmash.
And the Ukrainian booster factory is located in the predominantly Russian speaking eastern region – making for an even more complicated situation.

By contrast, the SpaceX Falcon 9 rocket and Dragon cargo vessel is virtually entirely American built and not subject to economic embargoes.
At a US Congressional hearing held today (March 5) dealing with national security issues, SpaceX CEO Elon Musk underscored the crucial differences in availability between the Falcon 9 and Atlas V in this excerpt from his testimony:
“In light of Russia’s de facto annexation of the Ukraine’s Crimea region and the formal severing of military ties, the Atlas V cannot possibly be described as providing “assured access to space” for our nation when supply of the main engine depends on President Putin’s permission, said Space X CEO and founder Elon Musk, at the US Senate appropriations subcommittee hearing on Defense.

So, continuing operations of the ISS and US National Security are potentially held hostage to the whims of Russian President Vladimir Putin.
Russia has threatened to retaliate with sanctions against the West, if the West institutes sanctions against Russia.
The Crimean crisis is without a doubt the most dangerous East-West conflict since the end of the Cold War.
Right now no one knows the future outcome of the crisis in Crimea. Diplomats are talking but some limited military assets on both sides are reportedly on the move today.

Astronauts are expected to leave the International Space Station on schedule next week, and training continues on the ground, despite a crisis in Ukraine that is disrupting American and Russian relations, NASA’s administrator said on Tuesday (March 4).
Russian troops moved into the Crimea region of Ukraine last week, triggering condemnation from the United States and other International Space Station partners. At least one ISS participant, Canada, has removed its ambassador from Moscow.
“Everything is nominal right now in our relationship with the Russians. We continue to monitor the situation,” said NASA administrator Charles Bolden in a conference call with reporters.
“The safety of our crews and our assets that has not changed. Safety is the No. 1 of NASA’s core values, so we are constantly doing contingency planning on the International Space Station for emergencies that might arise,” Bolden added, citing the emergency ammonia pump replacement in December as one such example.
“Those are the kinds of things we are always planning for, and in terms of the situation on the ground, we will go into contingency planning for that as the situation dictates. But right now, we don’t see any reason to do so,” he said.

The Russian Soyuz is currently the only way that NASA can bring humans to the space station, although the agency is developing a commercial crew program to start lifting off astronauts from American soil again in 2017. The Soyuz missions depart and return from Kazakhstan under an agreement Russia has with the former Soviet Union republic.
Expedition 38 (which includes Russia’s Oleg Kotov and Sergey Ryazanskiy, and NASA’s Michael Hopkins) is expected to depart the space station March 10. Expedition 39 is scheduled to head to the ISS March 25.
Bolden avoided questions asking what sorts of contingencies NASA would consider if tensions escalated, saying the agency would evaluate that situation if it occurs.
The administrator delivered his comments as part of a conference call concerning NASA’s 2015 budget, which would increase funding for the commercial crew program to $848.3 million, up 21% from a planned $696 million in 2014. Proposals are currently being evaluated and little was said about CCP, except to note that the amount of funding would allow the program to have “competition”, implying multiple companies will be funded.

Russia was a key partner in the station’s construction from the beginning. It launched the first component (Zarya) to space in 1998, and the station today includes several other Russian modules and docking ports. Additionally, the Russians perform their own spacewalks using the Russian Orlan spacesuit. Cosmonauts also form a large percentage of ISS crews under space station utilization agreements.
NASA collaborations with Russia in space began with the Apollo-Soyuz Test Project in 1975, and expanded under an agreement that saw several shuttles dock with the Mir space station (and NASA astronauts train in Russia) in the 1990s.

Astronauts on the International Space Station “could have ignited flammable materials” on station while drying out a spacesuit that experienced a major leak during a spacewalk in July 2013, a new report reveals.
NASA Mission Control directed the Expedition 36 crew to use a vacuum cleaner to suction out the water, a procedure that inadvertently sucked up oxygen from the suit’s secondary high pressure oxygen tank, says a mishap report into the spacesuit leak incident. This “potentially hazardous risk” of electricity and pure oxygen created a fire hazard, the report added.
In a phone call with reporters yesterday (Feb. 27), report chair Chris Hansen added that the “levels of oxygen were perfectly safe” in this particular incident and that the “the risk to the crew in the end was none”, but said the incident still warranted attention in the 222-page report, which mainly deals with the spacesuit leak.
The incident occurred on July 17, 2013, one day after a “life-threatening” amount of water leaked into a spacesuit helmet used by Luca Parmitano, the report said. The astronauts and NASA were doing looking for the source of the leak. Astronauts reported no damage to the water bag and no water in the suit (which had been cleaned up after the spacewalk).

Next, they turned on the fan to the portable life support system (or backpack) with a secondary oxygen pack (SOP) check-out fixture. The fixture covered a vent port and oxygen switch for about 14 minutes. All appeared to be running normally, with no water detected. When the crew then removed the fixture (following procedure), they heard a “sucking” noise and the fan ceased moving, the report said.
“The crew was directed to turn off the suit fan and move the O2 Actuator to OFF. The crew then turned the suit fan back ON and again set the O2 Actuator to [the] IV [setting]. The fan briefly began spinning and then shut down almost immediately, with the crew reporting a water “sucking” or “gurgling” sound,” the report added.
The crew found “a few drops” of water in a canister outlet and “about a spoonful” of water in the suit inlet ports, as well as a few drops of water in a neck vent port. As the ground decided what to do, an infrared carbon-dioxide transducer in the suit “began to show an increase in its reading and eventually went off-scale high, most likely due to moisture in the vent loop near the CO2 [carbon dioxide] transducer,” the report stated.

With water in the suit, Mission Control then asked the crew to remove the water with a vacuum (one that is designed for wet or dry cleanup) as soon as the astronauts had the chance. Everything was normal until after the station emerged from a routine loss of signal, at which point controllers saw the secondary oxygen pack was turned on and reading 500 pounds per square inch lower than before the loss of communication.
“They quickly realized that their procedure had resulted in the EMU releasing 100% oxygen from the SOP into the vent loop, which was then sucked into the vacuum cleaner. This was a potentially dangerous situation involving unintended consequences,” the report said.
ISS Astronauts had to scramble to get Luca Parmitano out of his spacesuit after water leaked inside the suit, covering his face. Via NASA TV.
“During interviews, system experts indicated that they should have been able to anticipate SOP activation due to the reduced pressure created by the vacuum cleaner. The procedure was immediately stopped. No fire occurred and the crew was not harmed.”
In interviews after the incident, individuals spoke of “perceived pressure” to do the dry-out procedure quickly instead of first testing it on the ground with similar hardware. They instead used a non-functional spacesuit before directing the crew to do the procedure.
There were at least three factors contributing to that pressure, the report added: the desire to avoid corrosion in the suit, limited crew time, and the impending loss of signal.
The report did not identify any “additional causes, findings, or observations” from this event, noting that it is not technically an anomaly and was not classified as such in the NASA literature.

While NASA’s Mission Control “performed admirably” during a spacewalk water leak crisis in July, a report on the incident showed that controllers did not send astronaut Luca Parmitano back to the airlock until after he made three calls saying the water didn’t appear to be from a drinking bag.
There are several reasons this happened, the mishap report says, such as inadequate training, the crew members and ground misunderstanding the severity of the situation, and a (false) perception that any water leak is likely due to a problem with the drinking bag.
Another big problem was the “normalization of deviance”, similar language to what was used during in reports describing the Challenger and Columbia incidents. In this case, small amounts of water in the helmet was expected, and controllers also misunderstood the cause of a carbon dioxide alarm (a fairly regular occurrence during spacewalks).
The report pulls no punches when it describes how bad things were: “The presence of this water created a condition that was life threatening.”
While talking about what is in the report, it’s also important to point out what the investigators did not find. There was no evidence that contractors were afraid to bring up problems (such as what happened during the 1986 Challenger explosion), chair Chris Hanson told reporters yesterday. Also, while the suits are 35 years old, no aging problem was detected.
Another couple of cautions: the report is preliminary (the exact cause of the leak is under investigation), it’s lengthy (222 pages) and much of the technical information is unavailable to the public due to export control restrictions. Any news story will just scratch the surface of what happened and the recommendations to fix it.
That said, here are a few key points we found in the report.

Parmitano warned controllers multiple times. The transcript shows three separate calls from Parmitano saying it wasn’t the drinking bag at cause: (1) “I feel a lot of water on the back of my head, but I don’t think it is from my bag.” (2) “The leak is not from the water bag and it is increasing.” (3) “I’m thinking that it might not be the water bag.” (In between 1 and 2, he also sent another call saying his “only guess” was it was the drinking bag, but the report adds that Parmitano may have softened his stance after speaking to controllers). Misunderstanding about the severity, lack of training, “cognitive overload” of controllers, and space-to-ground-to-space communication difficulties are all cited as contributing factors.
Drink bags don’t actually leak as much as people think they did. Unequivocally, the mishap investigation board says “the perception that drink bags leak, especially as a frequent occurrence, is false.” There has never been an instance of a bag leaking substantially during a spacewalk, the report says. After the crisis passed and investigators had the luxury of time, they in fact identified seven separate possible sources of water: (1) the bag; (2) the waste collection garment; (3) cooling water from the sublimator heat rejection component of the suit; (4) the Liquid Cooling Ventilation Garment connector or the tubing itself; (5) transfer lines through the Hard Upper Torso; (6) water storage tankage through the pressurizing bladders; (7) the water separator circuit (which is where the problem was eventually found).
It was a risky decision to send Parmitano back alone. Twenty-three minutes after Parmitano warned of water in his helmet, NASA terminated the spacewalk and as per procedure, had the astronaut head to the airlock while crewmate Chris Cassidy performed cleanup tasks before doing the same. (“Terminate” has a specific meaning as opposed to “abort”, which means both crew members leave immediately.) By this time, water was in Parmitano’s eyes and the station had passed into the shadow of the Earth, forcing him to feel his way back to the airlock along the tether. (This was only his second spacewalk on station, too.) Also, the water affected his communications equipment, as he made several calls “in the blind” that were not heard. At this time, Cassidy and the ground controllers did not know how severe the situation was. “Additional risk exposure that the team could have considered was the aspiration of water, failure of comm equipment, and impaired visibility,” the report said.

The emphasis on science on station can hinder with maintenance tasks. NASA and other space station partners are eager to demonstrate how great the station is to science, but crew time is divided between that and doing maintenance tasks. “Due to this knowledge, team members felt that requesting on-orbit time for anything non-science related was likely to be denied and therefore tended to assume their next course of action could not include on-orbit time,” the report states. To give a specific example of how this affected Parmitano’s suit: After water was found in the suit during a previous spacewalk, the crew and ground essentially determined it was due to the drink bag and did not probe further, partly because of the perception that doing an investigation would take an inordinate amount of time for little return (as they believed they knew the cause). On a related note, there was also the concern that investigating this occurrence (which happened on July 9) would delay the July 16 spacewalk. (Again, this sounds a bit like Challenger, where time pressure was cited as a reason to launch despite icy conditions.)
More needs to be done to understand the physics of water in a spacesuit. A few examples: it was believed the fan would have failed if water got through the separator unit, which did not occur. It was also believed that any water in the helmet would cling to the helmet, and not the crew member’s face. Not only that, the training for crew and ground was inadequate to seek out water causes on the fly. “Had this been done, the crew and ground team may not have attributed water in the helmet to just the drink bag,” the report stated.
Water in the helmet was normalized. If you’ve read Chris Hadfield’s An Astronaut’s Guide to Life On Earth, there’s an account in there about how Hadfield (who also was a junior spacewalker in 2001) became temporarily blind due to an anti-fog agent on the helmet getting into his eyes. This has happened during other spacewalks, too, which meant that the ground team was used to small amounts of water in the helmet — even though this wasn’t a normal condition. Another aspect: a carbon dioxide alarm went off in Parmitano’s suit after it became saturated with water. This happened six minutes before he felt the dampness. The team attributed this to “nominal accumulation of moisture in the vent loop,” which can happen at the end of the spacewalk. Having it happen less than an hour in, however, did not trigger a fault-finding process.

While there are many, many causes in the report (with aspects ranging from the technical to the procedural to the training), members identified three main ones to the incident: (1) inorganic materials in the water separator drum holes, for reasons still unknown (2) a lack of understanding that meant the team’s response took longer than usual (3) a misdiagnosis of the water found during the July 9, 2013 spacewalk.
There are 49 separate recommendations ranging from “Level 1” priority to “Level 3”, which are still important but less urgent. NASA has pledged it will clear all “Level 1” and “Level 2” items before doing any normal spacewalks, although contingency ones are still possible. They expect this to be finished by June, but say they will take as long as needed to get the investigation done. There are no pressing spacewalk tasks on station right now.
Looking to the long run, the report noted that there should be more backups available if a fault is found in the spacesuits, as NASA is relying on these devices to perform essential station maintenance as far as 2028. Also, the investigators say that the six-year certification of these suits for orbital tasks is likely inadequate, and calls for a review of that. So although aging was not identified as an issue, maintenance and backups of the spacesuits could be key features of NASA thinking in the months and years to come.

NASA GODDARD SPACE FLIGHT CENTER, MARYLAND – Blastoff of the powerful and revolutionary new NASA/JAXA rain and snow precipitation measurement satellite atop a Japanese rocket from a tiny offshore island launch pad is now less than 24 hours away on Thursday, Feb. 27, EST (Feb. 28 JST).
The Global Precipitation Measurement (GPM) Core Observatory aimed at improving forecasts of extreme weather and climate change research has been given a green light for launch atop a Mitsubishi Heavy Industries H-IIA rocket from the Tanegashima Space Center on Tanegashima Island off southern Japan.
Roll out of the H-IIA launch vehicle from the Vehicle Assembly Building is scheduled for this evening, Feb. 26 at 11 p.m. EST.
Update: rocket rolled out. Photo below, plus watch streaming NASA TV below.
Following the Launch Readiness Review, mission managers approved the GO for liftoff.

Japanese team members also prayed at a Shinto ceremony for blessings for a successful launch at the Ebisu Shrine, the first shrine in a traditional San-ja Mairi, or Three Shrine Pilgrimage on Tuesday, Feb. 25, 2014 – see photo below.
However, the team also set a newly revised launch time of 1:37 p.m. EST (18:37 UTC, and Feb. 28 at 3:37 a.m. JST).
Mission managers adjusted the H-IIA launch time after concerns raised by a collision avoidance analysis between the GPM spacecraft and the International Space Station (ISS).
GPM will fly at an altitude of 253 miles (407 kilometers) above Earth – quite similar to the ISS.
It’s coverage runs over virtually the entire populated globe from 65 N to 65 S latitudes.
NASA plans live coverage of the launch on Feb. 27 beginning at 12 noon EST on NASA Television.
It will be streamed live at: http://www.nasa.gov/nasatv
The $933 Million observatory is a joint venture between the US and Japanese space agencies, NASA and the Japan Aerospace Exploration Agency (JAXA).

GPM is a next-generation satellite that will provide global, near real time observations of rain and snow from space. Such data is long awaited by climate scientists and weather forecasters.
It will open a new revolutionary era in global weather observing and climate science. Therefore it will have a direct impact on society and people’s daily lives worldwide.
The mission will significantly advance our understanding of Earth’s water and energy cycles and improve forecasting of extreme weather events.
The 3850 kilogram GPM satellite is equipped with two instruments – an advanced, higher resolution dual -frequency precipitation (DPR) radar instrument (Ku and Ka band) built by JAXA in Japan and the GPM microwave imager (GMI) built by Ball Aerospace in the US.

“The GPM satellite was built in house at NASA’s Goddard Space Flight Center in Maryland,” Art Azarbarzin, GPM project manager, told Universe Today during my exclusive up-close clean room inspection tour of the huge satellite as final processing was underway.
Researchers will use the GPM measurements to study climate change, freshwater resources, floods and droughts, and hurricane formation and tracking.
“GPM will join a worldwide constellation of current and planned satellites,” Azarbarzin told me during an interview in the Goddard cleanroom beside GPM.
“GPM is the direct follow-up to the currently orbiting TRMM satellite,” Azarbarzin explained.
“TRMM is reaching the end of its usable lifetime. After GPM launches we hope it has some overlap with observations from TRMM.”
“The Global Precipitation Measurement (GPM) observatory will provide high resolution global measurements of rain and snow every 3 hours,” Dalia Kirschbaum, GPM research scientist, told me during an interview at Goddard.
Stay tuned here for Ken’s continuing GPM reports and on-site coverage at NASA Goddard Space Flight Center in Maryland.
