Contingency Spacewalk Planned Next Week, But Dragon Must Arrive At Space Station First

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.

We will keep you apprised as circumstances warrant.

Failed Space Station Computer Spurs Contingency Spacewalk Plans

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.

Backup Computer Glitches On Space Station But Crew Safe, NASA Says

The International Space Station. Credit: NASA

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.

Twin Peeks: Astronaut Brothers To Go Under Microscope During One-Year Mission

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.)

A super secret US spy satellite soared spectacularly to space this afternoon from Cape Canaveral atop a very powerful version of the Atlas V rocket on a classified flight for the National Reconnaissance Office.

The United Launch Alliance (ULA) Atlas V carrying the NROL-67 intelligence gathering satellite on a US national security mission for the NRO lifted off from Space Launch Complex-41 ignited its engines precisely on the targeted time on April 10 at 1:45 p.m. EDT into brilliant blue Florida skies on Cape Canaveral Air Force Station.

This mighty version of the 191 ft (58 m) tall Atlas V whose thrust was augmented with four strap on solid rocket motors has only been used once before – to loft NASA’s Curiosity rover to the Red Planet back in November 2011.

Today’s Atlas V launch, as well as another for SpaceX/NASA, was postponed over two weeks ago from March 25 & 30 amidst final launch preparations when an electrical short completely knocked out use of the US Air Force’s crucial tracking radar that is mandatory to insure public safety for all launches on the Eastern Range.

Nothing is publicly known about the NROL surveillance satellite, its capabilities, orbit or mission or goals.

Due to the covert nature of this mission, the flight entered the now standard total news blackout and the TV transmission ceased barely five minutes after liftoff.

The successful blastoff follows closely on the heels of another Atlas V launch just seven days ago.

On April 3, ULA launched a less powerful version of the Atlas V carrying an Air Force weather satellite from Vandenberg Air Force Base, Calif.

“We are honored to deliver this national security asset to orbit together with our customers the NRO Office of Space Launch and the Air Force,” said Jim Sponnick, ULA vice president, Atlas and Delta Programs.

“Successfully launching two missions from two different coasts in just seven days is a testament to the team’s one-launch-at-a-time focus and ULA’s commitment to mission success and schedule reliability.”

Today’s liftoff involved use of the Atlas V in the 541 configuration. The NROL-67 payload was housed inside a 5-meter diameter payload fairing. And a total of four US built Aerojet Rocketdyne solid rocket motors were mounted on the first stage of the booster.

The Centaur upper stage which boosted NROL-67 to Earth orbit was powered by a single Aerojet Rocketdyne RL10A engine.

The Atlas V first stage was also powered by the dual nozzle RD AMROSS RD-180 engine manufactured in Russia.

Use of the Russian designed and built RD AMROSS RD-180 engine potentially puts Atlas V launches and US National Security launches at risk, if the crisis in Ukraine and Crimea spins out of control as I have reported previously.

“ULA maintains a two year stockpile of the RD-180 engines at all times,” ULA Jessica Rye spokesperson told me recently at Cape Canaveral Air Force Station.

The next ULA launch from the Cape is scheduled for May 15 when a Delta IV rocket will loft the GPS IIF-6 mission for the United States Air Force from Space Launch Complex-37.

A SpaceX Falcon 9 is slated to launch on Monday, April 14 at 4:58 p.m. EDT.

The Falcon 9 is lofting a SpaceX Dragon cargo ship and delivering some 5000 pounds of science experiments and supplies for the six man space station crew – under a resupply contract with NASA.

Also packed aboard the Dragon are a pair of legs for NASA’s experimental Robonaut 2 crew member.

European Satellite Dodged Space Debris Hours After Reaching Orbit

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.

You can read more about the situation in the blog post. ESA’s main Twitter feed and the ESA Operations Twitter feed also first reported the near-collision yesterday, nearly a week after it occurred. It should also be noted that the Europeans (among many other space agencies) are looking at ways to reduce space debris.

Do You Know 80s Kid Who Inspired Virgin Galactic? Branson Asks For Help Ahead Of First Spaceflight

As Virgin Galactic aims for a spaceflight this year, founder Richard Branson is asking the public to help track down the kid (now an adult) who prompted him to start the company 26 years ago.

Above you can see a Virgin video showing an 1988 clip from an old BBC show called “Going Live!” Branson answered a question from a young fan, Shihan Musafer, asking if he’d go to space. Of course, you all know what his answer was.

“After that call, I set about registering the name Virgin Galactic,” Branson wrote in a blog post. “We’d love to track down Shihan to say a personal thank you for helping to inspire the idea with that phone call. We want to offer Shihan the chance to join Virgin Galactic as a VIP guest to witness a spaceflight.”

If you have any information, Branson encourages you to tweet @richardbranson and @virgingalactic with the hashtag #shihanmusafer. (Early results on Twitter show a lot of retweets and few ideas of how to find him.) Meanwhile, his company has been busy putting SpaceShipTwo through its paces, making powered test flights — such as this one you can see from January.

US Spy Sat and SpaceX Set for Double Barreled Blastoffs After Critical Cape Canaveral Radar Revitalized

The Florida Space Coast is about to ignite with a doubled barreled dose of spectacular rocket launches from Cape Canaveral over the next few days that were suddenly postponed two weeks ago amidst final launch preparations when an electrical short completely knocked out use of the US Air Force’s crucial tracking radar that is mandatory to insure public safety.

A pair of liftoffs vital to US National Security and NASA/SpaceX are now slated for April 10 and April 14 from Cape Canaveral Air Force Station after revitalizing the radar systems.

The tracking radar is an absolutely essential asset for the Eastern Range that oversees all launches from Cape Canaveral Air Force Station and the Kennedy Space Center in Florida.

The United Launch Alliance Atlas V is now slated to launch on Thursday, April 10 at 1:45 p.m. EDT.

The Atlas V rocket is carrying the super secret NROL-67 intelligence gathering spy satellite for the National Reconnaissance Office (NRO).

The SpaceX Falcon 9 is slated to launch on Monday, April 14 at 4:58 p.m. EDT.

The Falcon 9 is lofting a SpaceX Dragon cargo ship and delivering some 5000 pounds of science experiments and supplies for the six man space station crew – under a resupply contract with NASA.

The pair of liftoffs of the Atlas V and Falcon 9 boosters for the NRO and SpaceX/NASA had been slated just days apart on March 25 and March 30, respectively.

I was on site at Cape Canaveral Launch Pad 41 photographing the Atlas V rocket carrying the NRO payload in anticipation of the launch.

Shortly thereafter a fire of unexplained origin in the radar equipment unexpected occurred and knocked the tracking radar off line. When no quick fix was possible, both launches were delayed indefinitely pending repairs.

“The tracking radar experienced an electrical short, overheating the unit and rendering the radar inoperable,” said the USAF in a statement I received from the 45th Space Wing that controls the critical launch control systems, communications, computers and radar elements at the Eastern Range.

On Monday, April 7, the Air Force announced that range repairs were on target and that a retired, inactive radar had been brought back online.

“A radar that was previously in standby status has been brought back to operational status while the repair work is being accomplished,” said the USAF in a statement.

A fully functional tracking radar is an absolute requirement to ensure the success and safety of every rocket launch.

Insufficient maintenance and antiquated equipment due to a lack of US government funding and investment in infrastructure may be at fault for the electrical short.

The Eastern range radar must function perfectly in order to destroy any rocket in a split second in the event it abruptly veers off course towards the nearby populated areas along the Florida Space Coast.

The Atlas V rocket was rolled out earlier today to Space Launch Complex 41 in preparation for Thursday’s NROL-67 launch. The weather forecast shows a 90 percent chance of favorable weather conditions for launch.

NASA Severs Most Ties With Russia, Sparing Station But Pushing For U.S. Launches Again

NASA plans to cease most work with the Russian Federal Space Agency amid growing tensions concerning the Ukrainian crisis, a spokesperson confirmed with a statement to Universe Today Wednesday evening (April 2).

While the International Space Station will still see work to “maintain safe and continuous operation”, most other NASA activities with Roscosmos will cease, the statement read. It added (citing the Obama administration) that Congress now faces a choice between fully funding human U.S. launches again in 2017, or facing years more of sending money to the Russians for Soyuz launches from Kazakhstan.

In full, this is the statement that Bob Jacobs, NASA’s deputy associate administrator of communications, sent to Universe Today (UPDATE, 8:54 p.m. EDT — this is also now available on NASA’s G+ page)

Given Russia’s ongoing violation of Ukraine’s sovereignty and territorial integrity, NASA is suspending the majority of its ongoing engagements with the Russian Federation. NASA and Roscosmos will, however, continue to work together to maintain safe and continuous operation of the International Space Station.

NASA is laser focused on a plan to return human spaceflight launches to American soil, and end our reliance on Russia to get into space. This has been a top priority of the Obama Administration’s for the past five years, and had our plan been fully funded, we would have returned American human spaceflight launches – and the jobs they support – back to the United States next year.

With the reduced level of funding approved by Congress, we’re now looking at launching from U.S. soil in 2017. The choice here is between fully funding the plan to bring space launches back to America or continuing to send millions of dollars to the Russians. It’s that simple. The Obama Administration chooses to invest in America – and we are hopeful that Congress will do the same.

It is unclear from this statement exactly what activities would constitute “safe and continuous operation” of station. So, for example, it’s unclear so far if (for example) NASA will still send photographers to cover launches and landing in Russia, or to what extent NASA TV broadcasts of Russian spacewalks would be affected.

Since the shuttle retired in 2011, NASA and other space agencies such as the European Space Agency have relied on Russian Soyuz spacecraft to bring astronauts to the International Space Station. Crews are generally made up of large proportions of Russian cosmonauts and American astronauts, as well as a few astronauts from other agencies. The current Expedition 39 crew has has three Russians, two Americans and a Japanese commander, Koichi Wakata. Expedition 40 will launch aboard a Soyuz spacecraft in May, if all goes to plan.

The human spaceflight relationship between NASA and Russia stretches back to the 1970s when Russia was then the Soviet Union. Their first joint mission was with the Apollo-Soyuz Test Project in 1975. That relationship expanded when several NASA shuttles visited the Russian space station Mir in the 1990s, laying the groundwork for the International Space Station agreement today.

NASA is working on a commercial crew program that right now is slated to bring U.S. astronauts into space from American soil again in 2017. There are several proposals being considered: a human-rated version of SpaceX’s Dragon, Blue Origin’s New Shepard, Sierra Nevada Corp.’s Dream Chaser and the Boeing Co.’s CST-100. NASA releases regular updates on how these companies — most of which receive money from the agency for development — are progressing, with the most recent update coming March 31.

It is unclear, however, how much money CCP will receive in the upcoming fiscal 2015 budget request before Congress. Historically, NASA receives less money for this program than what the agency requests (which has pushed back launches by a few years). The new tensions with Russia, however, could make things different this time around. This seems to be what NASA is counting on in the statement.

As far as what missions could be affected due to cooperation with Russia, planetary scientist Barbara Cohen said on Twitter that while it may appear the US may do little with Russia beyond the International Space Station, cooperation in planetary science is rather big. Russian scientists contribute to several ongoing and upcoming NASA robotic missions, and US scientists are contributing to the planning for ExoMars, which is an ESA-Roscosmos mission, and the US is contributing Elektra telecommunication radios to the orbiter and part of a mass spectrometer for the rover. Additionally, US scientists are working with the Verera-D mission, a strategic Venus mission sponsored by Roscosmos, with participation by NASA’s Planetary Science Division.

The news of the breach comes about a month after NASA administrator Charlie Bolden told reporters that the Russian diplomacy crisis, which erupted after troops went to Crimea a few weeks ago (to U.S. and other countries’ condemnation), would not affect Soyuz launches or other activities related to the space station.

Screenshot from NASA TV of the Soyuz TMA-09M spacecraft arriving at the International Space Station.

“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 March 4, following the release of NASA’s preliminary budget request.

“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 an 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 added.

International Space Station operations were recently extended to at least 2024, and NASA officials have pointed out that it and similar agreements have weathered other world crises.

Wednesday’s news first came to light in a reported internal memo posted on SpaceRef’s website that morning. Jacobs did not confirm or deny the memo’s authenticity in the e-mail to Universe Today.

SpaceX’s Next-Generation Reusable Rocket Roars In Tie-Down Test

As SpaceX pursues its quest of rocket reusability, it recently subjected the first stage of its next generation Falcon 9 rocket (called the Falcon 9-reusable or F9R) to a tie-down test ahead of some more heavy-duty work in the coming months and years. Early indications are that the test was a success, the firm said.

Details of the rocket are still scance on the SpaceX’s website, but the California-based company said that the rocket would generate about a million pounds of thrust at sea level, and 1.5 million pounds in space. It’s also a sort of follow-on from the leaping reusable Grasshopper rocket that retired last year.

Rockets are usually the “throwaway” items in a flight, but SpaceX is betting that by creating a reusable one that it will save on launch costs in the long run. (The rocket has been tested before, such as this long-duration one last June.)

“F9R test flights in New Mexico will allow us to test at higher altitudes than we are permitted for at our test site in Texas, to do more with unpowered guidance and to prove out landing cases that are more-flight like,” SpaceX stated in the YouTube video description.

SpaceX’s next launch to the space station was supposed to be in March, but it was scrubbed due to a radar outage that is affecting several launches. You can read more about the Falcon 9 rocket’s development (including the addition of landing legs) in this recent Universe Today article by Ken Kremer.
