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

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.)

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.

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’s car sized Curiosity rover has arrived at a scientifically enticing science destination at “The Kimberley Waypoint” where researchers hope to carry out the next drilling operation into alien Martian terrain in search of further clues about ancient Red Planet environments that may have been favorable for life.

“We are officially in ‘The Kimberley’ now,” Curiosity Principal Investigator John Grotzinger, of the California Institute of Technology, Pasadena, told Universe Today.

Since arriving in the Kimberley region, Curiosity’s earth-bound handlers have been maneuvering the 1 ton robot to thoroughly survey the destination dubbed “The Kimberley”.

Why was Kimberley chosen as a science destination?

“The Kimberley” has interesting, complex stratigraphy,” Grotzinger told me.

The team moved the six wheeled robot further this week in search of a suitable location to conduct the next drilling operation. The terrain is replete with diverse rock types and extensive outcrops.

I asked Grotzinger if today’s (April 5) location at ‘The Kimberley’ is the intended drill site?

“It’s a possible drill site,” Grotzinger replied.

“Pending further evaluation,” he noted.

Curiosity drove the final stretch of some 98 feet (30 meters) on Wednesday, April 2, required to arrive at a major stopping waypoint planned since early 2013 for up close study of the Red Planet’s rocks.

Along the recent dune filled path to ‘The Kimberley’, Curiosity snapped breathtaking landscapes around the irresistible ‘Junda’ outcrop, much like a tourist.

The state-of-the-art robot now sits at a vantage point at “The Kimberley” enabling a detailed photographic survey of the rock exposures and surroundings with the high resolution Mastcam cameras.

The new imagery will be used to select the most scientifically productive drilling locations.

“It is named after a remote region of western Australia,” Grotzinger informed me.

The team chose Kimberley because its lies at the intersection of four different types of rocks, including striated rocks overlain by others and deposited in a decipherable geological relationship to each other.

Researchers directed Curiosity on a pinpoint drive to ‘Kimberley’ after high resolution imagery and mineral mapping spectrometry gathered by NASA’s powerful telescopic cameras aboard the Mars Reconnaissance Orbiter (MRO) circling overhead piqued their interest.

“This is the spot on the map we’ve been headed for, on a little rise that gives us a great view for context imaging of the outcrops at the Kimberley,” said Melissa Rice, Curiosity science planning lead, of Caltech.

The team expects Curiosity to investigate Kimberley for several weeks of observations, including sample-drilling and onboard laboratory analysis of the area’s rocks with the CheMin and SAM miniaturized chemistry labs.

If drilling is warranted, Kimberley would be the site of Curiosity’s first drilling operation since boring into the ‘John Klein’ and ‘Cumberland’ outcrop targets during the spring of 2013 at Yellowknife Bay.

The robot has conducted cleaning activities of SAM, CheMin and the CHIMRA sample handling mechanism in anticipation of boring into the Martian outcrops and delivering powdery, pulverized samples of cored Martian rocks to SAM and CheMin – waiting patiently inside the robots belly to eat something exciting from the Red Planet.

Curiosity departed the Yellowknife Bay region in July 2013 where she discovered a habitable zone and thereby accomplished the primary goal of the mission.

To date, Curiosity’s odometer totals 3.8 miles (6.1 kilometers) since landing inside Gale Crater on Mars in August 2012. She has taken over 137,000 images.

The sedimentary foothills of Mount Sharp, which reaches 3.4 miles (5.5 km) into the Martian sky, is the 1 ton robots ultimate destination inside Gale Crater because it holds caches of water altered minerals. Such minerals could possibly indicate locations that sustained potential Martian life forms, past or present, if they ever existed.

Curiosity has some 4 kilometers to go to reach the base of Mount Sharp.

She may arrive at the lower reaches of Mount Sharp sometime in the latter half of 2014, but must first pass through a potentially treacherous dune field.

Meanwhile, NASA’s sister Opportunity rover is exploring clay mineral outcrops by the summit of Solander Point on the opposite side of Mars at the start of her 2nd Decade investigating the Red Planet’s mysteries.

A pair of new orbiters are streaking to the Red Planet to fortify Earth’s invasion fleet- NASA’s MAVEN and India’s MOM.

When will LADEE hit the Moon for its looming end of mission finale?

NASA’s resoundingly successful LADEE lunar dust exploring mission is nearly out of gas – and needs your help, now!

With its inevitable doom approaching, NASA needs you to summon your thoughts and is challenging you to participate in a ‘Take the Plunge’ contest – figuratively not literally – and guess LADEE’s impending impact date.

LADEE, which stand for Lunar Atmosphere and Dust Environment Explorer, will smack violently into the Moon and scatter into zillions of bits and pieces sometime in the next two and a half weeks, on or before about April 21.

But exactly when will it impact the lunar surface? NASA wants to hear your best guess!

The ‘Take the Plunge’ contest was announced by NASA today, April 4, at a media briefing.

For more information about the challenge and how to enter, visit: http://socialforms.nasa.gov/ladee

Between now and its inevitable doom, mission controllers will command LADEE to continue gathering groundbreaking science.

And it will do so at an even lower attitude that it orbits today by firing its orbit maneuvering thrusters tonight and this weekend.

The couch sized probe seeks to eek out every last smidgeon of data about the Moons ultra tenuous dust and atmospheric environment from an ultra low altitude just a few miles (km) above the pockmarked lunar surface.

But because the moon’s gravity field is so uneven, the probes thrusters must be frequently fired to keep it on course and prevent premature crashes.

“The moon’s gravity field is so lumpy, and the terrain is so highly variable with crater ridges and valleys that frequent maneuvers are required or the LADEE spacecraft will impact the moon’s surface,” said Butler Hine, LADEE project manager at Ames.

“Even if we perform all maneuvers perfectly, there’s still a chance LADEE could impact the moon sometime before April 21, which is when we expect LADEE’s orbit to naturally decay after using all the fuel onboard.”

LADEE will fly as low as fly approximately 1 to 2 miles (2 to 3 kilometers) above the surface.

Everyone of all ages is eligible to enter NASA’s “Take the Plunge: LADEE Impact Challenge.”

The submissions deadline is 3 p.m. PDT Friday, April 11.

NASA says that winners post impact. They will receive a commemorative, personalized certificate from the LADEE program via email.

Watch for my upcoming story on LADEE’s science accomplishments and what’s planned for her final days.

LADEE was launched on Sept. 6, 2013 from NASA Wallops in Virginia on a science mission to investigate the composition and properties of the Moon’s pristine and extremely tenuous atmosphere, or exosphere, and untangle the mysteries of its lofted lunar dust dating back to the Apollo Moon landing era.

The science mission duration had initially been planned to last approximately 100 days and finish with a final impact on the Moon on about March 24th.

NASA granted LADEE a month long extension since the residual rocket fuel is more than anticipated due to the expertise of LADEE’s navigation engineers and the precision of the launch atop the Orbital Sciences Minotaur V rocket and orbital insertion.

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.

“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.

Have A Heart! This Organ Plays Shape-Shifter In Space, Leading To Mars Mission Questions

Could a long mission to Mars increase your risk of heart problems back on Earth? That’s something that scientists are trying to better understand after discovering that hearts become temporarily rounder in space, at least in a study of 12 astronauts.

The finding doesn’t appear to be a big surprise for cardiovascular scientists, however, who had the astronauts examine their hearts using ultrasound machines on the International Space Station as well as before and after spaceflight. The heart gets 9.4 percent more round, similar to models developed for the project, before returning to its normal shape on Earth.

“The heart doesn’t work as hard in space, which can cause a loss of muscle mass,” stated James Thomas, lead scientist for ultrasound at NASA, and senior author of the study. “That can have serious consequences after the return to Earth, so we’re looking into whether there are measures that can be taken to prevent or counteract that loss.”

Astronauts typically spend six months on the International Space Station. One year from now, NASA’s Scott Kelly and Roscomos’ Mikhail Kornienko are going to launch for a one-year mission. Spending months upon months in space leads to a host of problems upon returning to Earth. Your muscles get weaker, you’re more likely to pass out, and you’re at increased risk of bone fractures, among other problems.

A typical person on the space station spends two hours a day exercising just to ward off the worst of the effects. The researchers added that one remedy could be to add more exercises targeting the heart. This will be particularly important for missions that last 12 to 18 months or more — such as a Mars mission.

Studying astronauts in space could provide data on Earth-bound patients facing similar problems, the researchers said. Since the models that they made for astronauts were so congruent with reality, this gives the researchers confidence that they could create similar models for patients on Earth.

Conditions that could be considered include ischemic heart disease (the most common kind of heart disease and source of heart attacks), hypertrophic cardiomyopathy (thickened heart muscle)  and valvular heart disease (damage to one of the heart’s valves).

Results were presented last week at the American College of Cardiology’s annual conference. It’s not immediately clear from a press release if the study was peer-reviewed. The researchers added that more study of astronauts after returning to Earth could be a useful research direction, to see how the effects persist (if at all.)
