And now, time for some thrilling heroics. NASA astronaut Steve Swanson sent out the first Instagram from space last week wearing none other than a Firefly T-shirt. There’s something to be said about a space-faring guy evoking images of Captain Mal doing the impossible in the plucky Serenity spaceship, isn’t there?
We’re happy the epicness did not break NASA’s Instagram feed, as Swanson has been sending out pictures regularly since then showing the view from orbit (he joked about wanting a vacation at one point) as well as another selfie. You can check out the magic below, and follow the rest on NASA’s Instagram feed. We’ve copied and pasted Swanson’s captions below each image.
During Swanson’s first mission to space in 2007, STS-117, he brought with him the DVD set of Firefly and its movie spinoff, Serenity, and left it on the International Space Station library, according to collectSPACE.
Oh, and social media from space is also being covered on Twitter, via Expedition 39 NASA astronaut Rick Mastracchio and Koichi Wakata, from the Japan Aerospace Exploration Agency.

Star Trek replicators, here we come. The European Space Agency has released a list of how 3-D printing could change space exploration forever. And lest you think this type of printing is far in the future, images like those disembodied hands above show you it’s come a long way. Those are 3-D replicas of a glove worn by European Space Agency astronaut Hans Schlegal.
The applications range from the small — making lighter valves, for example — to ambitious projects such as constructing a moon base. Below are some ESA images showing uses for 3-D printing, and if they’ve missed some, be sure to let us know in the comments.

While people across North America marvelled at the blood-red moon early this morning, some NASA engineers had a different topic on their minds: making sure the Lunar Reconnaissance Orbiter would survive the period of extended shadow during the eclipse.
LRO uses solar panels to get energy for its batteries, so for two passes through the Earth’s shadow it would not be able to get any sunlight at all. Tweets on the official account show all as well in the first few hours after the eclipse.
“The spacecraft will be going straight from the moon’s shadow to the Earth’s shadow while it orbits during the eclipse,” stated Noah Petro, LRO’s deputy project scientist at NASA’s Goddard Space Flight Center, in a release before the eclipse occurred.
“We’re taking precautions to make sure everything is fine,” Petro added. “We’re turning off the instruments and will monitor the spacecraft every few hours when it’s visible from Earth.”
LRO’s Twitter account asked “Who turned off the heat and lights?” during the eclipse, then reported a happy acquisition of signal after the shadow passed by. “AOS, and sunlight, sweet sunlight! My batteries are charging again before I make another trip to the lunar far side.”
Hear more about LRO’s eclipse journey in the video below. For more information, check out NASA’s LRO website. UPDATE, 10:28 a.m. EDT: NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft also is fine after the eclipse, according to its Twitter account.

When planning for long-duration space travel, many people would think along the lines of not forgetting a towel or something of that nature. But we on Earth who are spoiled by the astounding pictures beamed from space must realize that even astronauts can get tired of looking at the same few walls for months at a time.
Scott Kelly is going to spend a year in space in 2015, and he highlighted boredom as one of the things he will need to fight against during his time on the International Space Station.
“There are things I will do a little bit differently with regards to pacing myself. You wouldn’t think this is true, but you do have to kind of stay entertained over that kind of period,” said Scott Kelly in a NASA interview late last week, which you can watch above.
“No matter how exciting that kind of things is, no matter how beautiful the Earth is, when you’re doing it for a year there is still the factor of trying to keep yourself engaged and interested.”
Kelly also highlighted some of the training challenges he will face being that he will be up there twice as long as the typical six-month space station mission. While it won’t take twice as long to do emergency training, he is required to do it with twice as many astronauts/cosmonauts because he will be working with four crews in space.
He also will train with two different Soyuz spacecraft commanders (which will add “complexity”, he noted) and have twice as much science to perform. That includes several “twin” studies where scientists will compare Kelly and his identical brother Mark, a four-time shuttle flyer who retired from the program in 2011.
Another lesson learned from his last six-month flight in 2010? “I know what I want to bring this time that I didn’t have last time,” Kelly said, although he didn’t elaborate on what those items are.
Kelly and Russian cosmonaut Mikhail Kornienko will begin their mission just under one year from now.

Following closely on the heels of Thursday’s spectacular Atlas V rocket blastoff from Cape Canaveral and a last moment computer failure at the ISS over the weekend, an upgraded Space X Falcon 9 rocket is now poised to launch on Monday (April 14) and complete a double barreled salvo of liftoffs from the Florida Space Coast merely 4 days apart – if all goes well.
The SpaceX Falcon 9 rocket carrying a Dragon resupply freighter is slated to launch on Monday at 4:58 p.m. EDT, 2058 GMT, from Launch Complex 40 at the Cape Canaveral Air Force Station, Fla.
Update 4/14- 345 PM: Todays launch attempt scrubbed due to 1st stage Helium leak. Friday is earliest target date
This flight marks the third operational Dragon resupply mission to the 1 million pound International Space Station (ISS).
NASA TV live coverage will begin at 3:45 p.m. EDT and conclude at approximately 5:20 p.m.
Weather forecasters are predicting an 80 percent chance of favorable weather conditions at the scheduled liftoff time.

Monday’s launch was temporarily put in doubt by the unexpected loss on Friday (April 11) of a backup computer command relay box called a multiplexer/demultiplexer (MDM) that resides in the station’s S0 truss.
The primary MDM continued to function normally.
The MDM’s provide commanding to the station’s external cooling system, Solar Alpha Rotary joints, Mobile Transporter rail car and insight into other truss systems.
It must function in order for the astronauts to use the robotic arm to grapple and berth the Dragon at a station docking port when it arrives on Wednesday, April 16, at about 7 a.m. EDT.
NASA managers held an extensive series of review meetings since Friday with ISS program managers, station partners, and SpaceX to exhaustively consider all possibilities and insure it was safe to fly the Dragon mission.
NASA gave the final go ahead after a readiness review this Sunday morning of managers, engineers and flight controllers.
ISS crew members will conduct a spacewalk to replace the failed MDM unit after the Dragon arrives.
This unmanned SpaceX mission dubbed CRS-3 mission will deliver some 5000 pounds of science experiments, a pair of hi tech legs for Robonaut 2, a high definition imaging camera suite, an optical communications experiment (OPALS) and essential gear, the VEGGIE lettuce growing experiment, 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.

This launch has already been postponed twice since mid-March.
The original March 16 launch target was postponed 2 days before liftoff due to contamination issues with insulation blankets located inside the unpressurized trunk section of Dragon.
The second postponement from March 30 occurred when an electrical short knocked out the critical Air Force tracking required to insure a safe launch from the Eastern Range in case the rocket veers off course towards populated ares and has to be destroyed in a split second.
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. The last flight dubbed CRS-2 blasted off a year ago on March 1, 2013 atop the initial version of the Falcon 9 rocket.

Credit: SpaceXAnother major goal for SpaceX with this launch involves the attachment of landing legs to the first stage of the firm’s next-generation Falcon 9 rocket that counts as a major first step towards a 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.
Eventually SpaceX will test land landings in a ramped up series of rocket tests

As contingency spacewalks go, the urgent task should be easy: a quick 2.5-hour run to swap out a failed backup computer that controls several systems on the International Space Station, including robotics. But NASA doesn’t want to go ahead with it until spare spacesuit parts arrive, in the aftermath of a life-threatening suit leak that took place last summer.
Those parts are on board the much-delayed SpaceX Dragon spacecraft sitting on a launch pad waiting for its next window to open. For this and other reasons, NASA decided to move ahead with the launch as planned Monday at 4:58 p.m. EDT (8:58 p.m. UTC). The spacewalk would take place April 22 — if Dragon gets there as planned on Wednesday.
“We need to get it [Dragon] on board as soon as we practically can,” said Mike Suffredini, the International Space Station’s program manager, in a phone briefing with reporters Sunday (April 13). That’s because Dragon is carrying a new spacesuit, components to fix an existing spacesuit, critical research experiments and food for the six crew members of Expedition 39.
The challenge, however, is making sure the station could be ready even if the primary multiplexer demultiplexer (MDM) fails before spacewalkers can make the backup replacement. There are more than a dozen MDMs on station, but each one controls different functions. This primary MDM not only controls a robotics mobile transporter, but also radiators and a joint to move the station’s solar arrays, among other things. The computer sits on the S0 truss on station, which you can view in the diagram below.

“The biggest driver for us is the positioning of the solar arrays as we look to the next failure,” Suffredini said. NASA needs to reposition the arrays when a vehicle approaches because plumes from the thrusters can put extra “loads” or electrical power on the system.
At the same time, enough power must flow to the station for it to operate. Luckily, the angle of the sun is such these days that the array can sit in the same spot for a while, at least two to three weeks, Suffredini said. NASA configured the station so that even if the primary computer fails, the array will automatically position correctly.
NASA also will move a mobile transporter on station today so that the station’s robotic arm is ready to grasp the Dragon when it arrives, meaning that even if the primary computer fails the transporter will be in the right spot. If Dragon is delayed again, the next launch opportunity is April 18 and the spacewalk would be pushed back.
Dragon’s precious payload of items includes several intended to make NASA spacewalks safer. The suit leak was due to contamination in the fan pump separator of Suit 3011 that plugged a tiny hole inside the water separation part of the unit. Water then escaped and got into the helmet, causing a near-emergency for Luca Parmitano — who was using the spacesuit in July.

NASA installed snorkels and absorbent helmet pads into its spacesuits while awaiting the results of an investigation, and also pushing back all nonessential spacewalks. The agency now has recommendations in hand and is addressing those with the hope of resuming non-contingency spacewalks this summer.
Today, Suffredini also provided an update on what the contamination was. “The anomaly was the result of contamination introduced by filters essentially used to clean and scrub the water loops for us,” he said.
“Those introduced large amounts of silica into the system, and that silica eventually coagulates in the area of the fan pump sep [separator] and after many uses, it eventually can build up to the point where it plugs the holes and you can’t separate the water from the air.”
The next spacewalk will use Suit 3011 (which got a new fan pump separator for contingency spacewalks in December) and Suit 3005, which will use the new separator on board Dragon. The cooling lines on spacesuits on board station have been purged with fresh water to reduce the silica buildup, and astronauts will use new filters that they know are clean.

If for some reason Suit 3005 can’t be used, Suffredini added, the new suit could be put in place instead after some testing to make sure it’s ready. “We’re in a very good posture for the EVA [extra-vehicular activity],” Suffredini said.
NASA hasn’t decided who will go on the spacewalks yet, he added. There are at least two or three spare MDMs on station; the one needed for this particular spacewalk is inside the U.S. Destiny laboratory, which is handily right next to the S0 truss and spacesuit worksite.
Of the “big 12” repair jobs the astronauts train for, the MDM replacement is among the easiest, Suffredini said, adding astronauts never encountered an external MDM failure on station before.
The last set of contingency spacewalks took place in December to replace a failed ammonia pump that affected science experiments on station. Expedition 39’s Rick Mastracchio was among the pair “outside” during those spacewalks.

NASA is preparing a contingency spacewalk to deal with a broken backup computer component on the International Space Station, the agency said in an update Saturday (April 12). While there’s no timeline yet for the spacewalk, the agency must consider carefully when to do it given a cargo ship is supposed to arrive at station on Wednesday.
The SpaceX Dragon spacecraft — already delayed due to an unrelated radar problem — is still scheduled to launch Monday at 4:58 p.m. EDT (8:58 p.m. UTC) to arrive at station two days later. Although the computer controls some robotic systems, NASA added the Canadarm2 that will grapple Dragon has other redundancies in place. The question is if the station itself has enough redundancy for the launch to go forward.
“A final decision on whether to launch Dragon Monday will not be made until another status meeting is conducted Sunday morning,” NASA stated.
The failure poses no risk to the crew and normal station operations are not affected, NASA emphasized. The failure was uncovered Friday “during a routine health check” of a box called EXT-2, which backs up a primary component that sits outside on the S0 truss (near the station’s center).

Earlier Saturday, a docked Progress robotic spacecraft boosted the station’s altitude in a planned maneuver to ready for the next Soyuz spacecraft launch, which will carry half of the Expedition 40 crew in May.
If spacewalks do go forward, this would be the second required contingency set required since Luca Parmitano experienced a life-threatening leak in a NASA spacesuit last July. NASA ordered an investigation, received a report in February and has halted all nonessential spacewalks while it addresses the recommendations. (Russian spacewalks in Orlan spacesuits are unaffected.)
The only NASA spacewalks that happened since summer took place in December, when an ammonia pump failure crippled science experiments on station. NASA’s Rick Mastracchio and his now returned-to-Earth crewmate Mike Hopkins performed two contingency spacewalks, successfully replacing the pump. The agency has snorkels and absorbent pads ready for its spacesuits as backup if another leak occurs.

A backup computer that controls “some systems associated with robotics” on the International Space Station is not “responding to commands”, NASA said in a late-night statement Eastern time Friday (April 11).
The crew is safe, there’s no “immediate” change to space station operations, and because the primary computer is working, there’s also no alteration to the SpaceX Dragon launch to the station on Monday — which requires the robotic Canadarm2 for berthing. NASA added, however, that there are “further evaluations” going on, meaning the date could change depending on what controllers figure out.
If the computer does need to be replaced, crew members of Expedition 39 will need to do at least one spacewalk, the agency added. NASA is allowing contingency spacewalks in American spacesuits to go forward as the agency addresses problems raised in a report about a life-threatening spacesuit leak in July.
Below the jump is the statement NASA put out tonight concerning the situation.
The Mission Control team at NASA’s Johnson Space Center in Houston confirmed Friday night that a backup computer on the exterior of the International Space Station (ISS) called a Multiplexer-Demultiplexer (MDM) is not responding to commands. The station’s MDM computers control some systems associated with robotics aboard the space station.
The primary MDM operating aboard the space station is functioning normally and there is no immediate impact to space station operations. The computer outage does not pose a risk to the six crew members aboard the space station. ISS teams are assessing next steps to attempt to bring the computer back online or replace it.
Replacing the backup MDM, if needed, would require a spacewalk. The backup MDM would provide redundancy for robotic systems that will be needed to attach the SpaceX Dragon spacecraft currently scheduled to launch on Monday and rendezvous with the ISS on Wednesday. NASA is continuing to work toward a Monday launch of the SpaceX cargo resupply mission pending further evaluations by the ISS Program. The latest information will be available here at www.nasa.gov/station.
We will keep you apprised as the situation progresses.

Identical twin astronauts, one headed to space for a year and the other happily at home. Imagine just how excited health researchers are by the prospect of this situation which yes, is happening for real. Scott Kelly is preparing to blast off on a lengthy mission to the International Space Station in 2015 while his retired twin, Mark, will serve as a control.
The 50-year-old men will do a suite of experiments before, during and after the mission to see how much (if at all) Scott’s body changes from his brother in the long term. This ranges from examining their DNA, to their vision, and even changes in the gut.
“These will not be 10 individual studies,” stated Craig Kundrot of NASA’s human research program at the Johnson Space Center. “The real power comes in combining them to form an integrated picture of all levels from biomolecular to psychological. We’ll be studying the entire astronaut.”
One experiment will examine telomeres, which NASA says are “molecular caps” that sit on the ends of human DNA. As the theory goes, these telomeres are affected in space by cosmic rays (high-energy particles originating from outside the solar system) — which could speed up the aging process. If Scott’s telomeres change after the mission, this could help determine if space is linked to rapid aging.
Another experiment asks how the immune system alters. “We already know that the human immune system changes in space. It’s not as strong as it is on the ground,” said Kundrot. “In one of the experiments, Mark and Scott will be given identical flu vaccines, and we will study how their immune systems react.”
Then there are experiments looking at gut bacteria that help digestion, seeking out how human vision changes, and even a phenomenon known as “space fog” — how some astronauts find themselves losing alertness in orbit.
Although the twins have inherent fascination for researchers and sociologists, the Kellys themselves have emphasized that to them, having an identical counterpart is something that always was.

“We didn’t know anything differently and, you know, he’s not my clone,” Scott said in a joint 2010 NASA interview with Mark.
“You know, a lot of times people would ask, ‘So what’s it like to be a twin?’ and … the response I would usually give is, ‘Well, what’s it like not to be a twin?’ I mean, it’s just, it is,” Mark added, to which Scott responded, “It’s more like … he’s my brother but we just happen to have the same birthday, to me.”
Scott will leave Earth with Russian cosmonaut Mikhail Kornienko in 2015 for the first one-year mission in space since a handful of lengthy stays on the former Russian space station, Mir, in the 1990s. Scott will serve as Expedition 43/44 flight engineer and have the distinction of commanding two space station missions, Expedition 45 and 46. (He also commanded Expedition 26 in 2010.)

Yesterday, the European Space Agency disclosed a serious problem early in the Sentinel-1A mission, which lifted off April 3 on a mission to observe the Earth. The spacecraft — which reportedly cost 280 million Euros ($384 million) to launch — came close to a collision in orbit.
“At the end of the first day after the launch (4 April): all deployments have been executed during the night and completed early in the morning at the beginning of the first ‘day shift’,” read a blog post from the Sentinel-1A team on the European Space Agency’s website.
“As the first day shift nears its end, a serious alert is received: there is a danger of a collision with a NASA satellite called ACRIMSAT, which has run out of fuel and can no longer be maneuvered. Not much information at the beginning, we are waiting for more information, but a collision avoidance maneuver may be needed. ‘Are you kidding? A collision avoidance maneuver during LEOP [launch and early orbit phase]? This has never been done before, this has not been simulated!’ ”
Worse, as controllers looked at the data they realized there was not one, but two possible points of collision. Cue the inevitable Gravity reference, and then a solution: to essentially move the satellite out of the way. The maneuver took about 39 seconds, and safely skirted Sentinel-1A out of danger.
