Mold on ISS plants

9:26 am

In December four of seven zinnia plants in a greenhouse on ISS became sickly or died because they were receiving too much water and developed mold.

The story doesn’t really tell us much, but this paragraph reveals I think some fundamental management problems in the way NASA is running the station:

ISS commander and NASA astronaut Scott Kelly reported the mold to Mission Control Dec. 22 just as Veggie principal investigator Trent Smith was trying to manage the water problem. In pictures, Smith saw water on the plants a few days before. He told Discovery News he was trying to relay a command from NASA’s station operations team to increase fan speed in Veggie, but the mold developed before the command could be put through. One solution was, on Christmas Eve, to designate Kelly “commander” of Veggie. Kelly now has more autonomy to make changes to Veggie’s conditions if he feels the plants need it.

The scientist noticed a problem but was unable to cut through the communications bureaucracy to talk to the astronauts so that changes could be made quickly. Meanwhile, the astronauts on board ISS had not been given the freedom to make common sense changes themselves. The result is that some of the plants died.

The solution, to give an astronaut more “autonomy”, is one that the Russians learned a long time ago on their Mir space station. It was also a lesson NASA learned even longer ago on Skylab. Moreover, when astronauts are finally flying interplanetary spaceships to the planets with greenhouses just like this, they will have to have that autonomy, no matter what rules NASA establishes. It seems amazing to me that NASA is still learning this lesson now.

One more thought: It is not really a problem that the scientist had trouble reaching the astronauts quickly. In fact, it probably indicates an area of management that NASA is handling well. Communications from the ground up to ISS can be a major problem, as everyone wants to talk to the astronauts and if NASA didn’t control that communications the astronauts would never have time to do anything. Thus, placing limits on that communications makes sense, though once again it also requires that the astronauts be given a great deal of freedom to make their own decisions, as they might not be able to talk to the right experts whenever necessary.

Europe might end its ISS partnership in 2020

9:26 am

Despite agreements by Russia, Canada, and Japan to extend their ISS partnership with the U.S. through 2024, both France and Germany of the European Space Agency (ESA) are having second thoughts and might pull out in 2020 instead.

In separate statements Jan. 4 and Jan. 5, the heads of the French and German space agencies said a detailed study is under way to assess the future operating cost of the station, and whether the cost can be justified given the pressure on near-term budgets.

Pascale Ehrenfreund, chairman of the board of the German Aerospace Center, DLR, which is Germany’s space agency, said DLR would make no promises until after a full review of ISS’s value. “In view of the high cost involved and the resulting implications on budgets of [European Space Agency] member states, we have to evaluate very carefully costs and benefits of a continued participation in the ISS,” Ehrenfreund said in a Jan. 5 statement in response to SpaceNews inquiries. “It’s only based on this evaluation that we will be able to take a definite position.”

Germany has been Europe’s ISS champion — its biggest paymaster and most vocal booster — for more than 20 years and at times has had to strong-arm France into boosting its support under threat of reduced German backing of Europe’s Ariane rocket program, a French priority.

Eventually, all the partners running ISS with the U.S. are going to come to this decision, which means the U.S. government should begin thinking about what it does at that time. I say, when that time comes the government will privatize the station, giving it to the private companies best able to make a profit from it. And by 2024 the U.S. is likely to have a number of companies quite capable of doing so, from SpaceX to Blue Origin to Bigelow.

There also will be no reason to destroy the station at that time. Being modular, much of it is relatively new, and what is old could be replaced with relatively simplicity. This is a national asset that should not be abandoned nonchalantly.

Russian officials decide to broadcast launches

10:12 am

The return of the Soviet Union! After experimenting with the online broadcast yesterday of the Soyuz manned launch, Russian officials announced today that they will continue these broadcasts on future launches.

The launch from Baikonur was for the first time broadcast via the Luch (Ray) satellite retransmission system. More than 1,000 people have watched the live broadcast.

The Luch system is designed to solve the problems of relaying information of monitoring and control of low-orbit spacecraft, manned space systems, including the Russian segment of the International Space Station, and to serve in controlling launch vehicle flights using an alternative technology. The Luch is a series of geosynchronous Russian relay satellites, used to transmit live TV images, communications and other telemetry from the Soviet/Russian space station Mir, the Russian Orbital Segment of the International Space Station and other orbital spacecraft to the Earth, in a manner similar to that of the US Tracking and Data Relay Satellite System. “One of the main spheres we intend to develop is our functions of mobile communications and data retransmission, including for the broadcast of launches as the most interesting events for the promotion of space exploration,” Komarov said. According to the Roscosmos chief, the Gonets company will be engaged in the development of this sphere. [emphasis mine]

Wow! A thousand people watched the launch! Isn’t that amazing!

In other words, either they didn’t make it easy for the public to find the broadcast online, or they didn’t make it public at all and the 1,000 viewers were merely government apparatchiks. It is clear from the article that they are still working to get their communication satellite network back into operation — which crumbled in the 1980s and 1990s with the collapse of the Soviet Union — but if they can broadcast to 1000 people they can broadcast to far more than that. Hopefully after this first effort they will broaden its access for future launches, though I wonder if that will happen. All of Russian aerospace is now government-controlled, and the natural inclination of government bureaucrats is to squelch information so that people don’t see bad things happen.

Soyuz docking issue during ISS arrival

9:37 am

When the manned Soyuz rendezvoused and docked with ISS yesterday, there was a problem with the automatic docking system, requiring the astronauts to take over and manually dock the spacecraft.

Initial reports suggested the failure was with the radar system having a conflict with the communications systems on the berthed Cygnus capsule. The link above instead claims the failure was caused by a malfunction in one of the Soyuz attitude thrusters. The former would be annoying but less of a concern than the latter. A thruster malfunction is somewhat rare, and would be another indication of the serious quality control problems in the Russian aerospace industry.

New astronaut crew to ISS, including Brit

8:47 am

A Russian Soyuz rocket today successfully launched a new crew to ISS, including Great Britain’s first official astronaut.

Tim Peake is not the first Brit in space, but he is the first paid for by the British government. The first British citizen to fly in space, back in 1991, was Helen Sharman, whose flight was a publicity stunt mostly paid for by the Russians themselves.

The crew is expected to dock with ISS later today.

Short circuit on ISS

8:39 am

An electrical failure on ISS has deprived ISS of one of its main circuits.

They have alternative wiring and are using that, so that all equipment is presently functioning. However, a similar failure in 2014 required a spacewalk to fix. Moreover, they don’t have the necessary spare parts on board to fix the problem. They will have to be shipped up, and it is too late to put them on the Cygnus freighter now packed and ready for launch on December 3.

Competition for ISS cargo contract reduced to three

9:50 pm

The competition heats up: With NASA once again delaying its decision on the next contract round for supplying cargo to ISS — this time to January — Boeing also revealed that NASA had eliminated the company from the competition, leaving only SpaceX, Orbital ATK, and Sierra Nevada in the running for the two contracts.

Earlier I had said that if the decision had been up to me, which of course it isn’t, I would pick Orbital and Sierra Nevada, since SpaceX and Boeing already have contracts to ferry crews to ISS. If you add Orbital’s Cygnus and Sierra Nevada’s reusable Dream Chaser, you then have four different spacecraft designs capable of bring payloads into orbit, a robust amount of redundancy that can’t be beat. When I wrote that I also noted that I thought it wouldn’t happen because Boeing’s clout with Congress and NASA would make it a winner.

With Boeing now out of the picture, it seems to me that the reason NASA has delayed its final decision again is that it wants to see what happens with the return to flight launches of Dragon and Cygnus in the next three months. A SpaceX Dragon success will cement that company’s position in the manned contract area, while an Orbital ATK Cygnus succuss will make picking them for a second contract seem less risky. In addition, maybe NASA wants Sierra Nevada to fly another glide test of its Dream Chaser test vehicle, and is now giving it the time to do so.

NASA to decide on 2nd cargo contracts Nov 5

9:40 am

The competition heats up: NASA will announce the two contract winners for its second round of ISS cargo contracts on November 5.

If it was up to me to pick the two winners from the four companies bidding, SpaceX, Boeing, Orbital ATK, and Sierra Nevada, I would go with Orbital ATK and Sierra Nevada. SpaceX and Boeing already have contracts to ferry crews to ISS with their Dragon and Starliner capsules. By picking Orbital ATK’s Cygnus capsule and Sierra Nevada’s Dream Chaser reusable mini-shuttle, NASA would then have four different ways to get payloads to ISS.

Sadly, the decision is not up to me. It is more likely NASA will pick SpaceX and Boeing. Boeing especially is likely to get picked because they are an established big player with lots of capital and influence.

Using fish to study bone loss in weightlessness

9:04 pm

A Japanese experiment on ISS, comparing the development of fish in weightlessness with those on the ground, has provided` scientists more information about bone density loss in weightlessness.

Akira Kudo at Tokyo Institute of Technology, together with scientists across Japan, have shown that medaka fish reared on the International Space Station for 56 days experienced increased osteoclast activity – bone cells involved in the re-absorption of bone tissue – likely leading to a subsequent reduction of bone density. They also found several genes that were upregulated in the fish during the space mission. The team generated fish with osteoclasts that emit a fluorescent signal. They sent 24 fish into space as juveniles, and monitored their development for 56 days under microgravity. The results were compared with a fish control group kept on Earth.

Kudo and his team found that bone mineral density in the pharyngeal bone (the jaw bone at the back of the throat) and the teeth of the fish reduced significantly, with decreased calcification by day 56 compared with the control group. This thinning of bone was accompanied by an increase in the volume and activity of osteoclasts. The team conducted whole transcriptome analysis of the fish jaws, and uncovered two strongly upregulated genes (fkbp5 and ddit4), together with 15 other mitochondria-related genes whose expression was also enhanced. Reduced movement under microgravity also has an influence. The fish began to exhibit unusual behavior towards the latter stages of their stay in space, showing motionless at day 47.

What the data mostly confirms is that long-term weightlessness is a bad thing for the development of bones, and not just in humans. Whether scientists can use these results to counter these harmful effects is not clear, however.

Yearlong mission on ISS reaches halfway point

9:25 am

The yearlong manned mission on ISS is now halfway over.

If they complete their planned 341-day mission through March, Mark Kelly and Mikhail Kornienko will have logged the fifth and sixth longest human flights in space. They will not complete a full year in space, (as has been advertised by NASA), something that four Russians did in their Mir space station, including one flight of fourteen and a half months.

I had not realized that this mission was not actually a complete year until I read the story above. In reality, they are actually only spending just over eleven months in space. I find this very disappointing. The whole reason to have ISS is to do these long missions. To cut this short of a year seems silly. If anything, they should take advantage of the situation and try to push to break the longevity mission of 14.5 months.

Whiskey tastes strange after being aged in space

12:08 pm

Whiskey that was aged for three years on ISS was taste-tested this past week in Scotland, and the testers all found the taste “completely unlike anything they have ever tasted before.”

The space whiskey had a much smokier quality, with flavors akin to cherries, prunes, raisins, and cinnamon, he said. He also noted that the whiskey’s aftertaste was “pungent, intense, and long, with hints of wood, antiseptic lozenges, and rubbery smoke.” This was in contrast to the Earth-aged whiskey, which had richer flavors more characteristic of whiskey drinks. The space whiskey still had strong flavor, but they were strange, Lumsden said — and not particularly good. He still has yet to figure out why. “That I haven’t been able to work out yet,” he said.

This is not the same Japanese whiskey that was recently sent up to ISS. That is a second experiment, along the same lines.

Soyuz capsule maneuvers to avoid space junk

8:53 am

The manned Soyuz capsule bringing three astronauts to ISS was forced to make a maneuver this morning to avoid a collision with a fragment from a Japanese rocket launched in 1989.

While space junk is an increasing problem, for a object to threaten a manned capsule making maneuvers in low Earth orbit is extremely rare. It appears from the story however that U.S. and Russian trackers thought there was a very good chance of an actual collision and took action to avoid it.

Technical problems for cosmic ray detector on ISS

9:53 am

The failure of a second of four cooling pumps on the Alpha Magnetic Spectrometer on ISS threatens the science instrument’s ability to continue its observations.

The AMS continues to gather science data using the three remaining pumps. They are part of a liquid carbon dioxide cooling system that is meant to dissipate heat as the AMS, which is on the outside of the space station, cycles in and out of sunlight during each 90-minute orbit of Earth Only one pump is needed at any given time. One failed in February 2014 and at least one of the other three is showing possible signs of trouble.

Since the 8.5-tonne AMS began operating in 2011, it has tracked more than 69 billion cosmic rays flying through its detectors. Its goal is to search for antimatter and dark matter. In 2013, AMS scientists reported measuring numbers and energies of positrons that hinted at, but did not confirm, the existence of dark matter.

The news article suggests that the instrument is now working with only one reliable pump. It also is possible that repairs might be done by astronauts on ISS during a spacewalk.

Some background: AMS cost $2 billion and about 20 years to build. It only got launched because Congress ordered NASA to launch one more shuttle mission to ISS to get it there.

Manned Soyuz heads for ISS with new crew

9:38 am

A new crew was successfully launched into orbit last night by a Russian Soyuz rocket.

This is the mission that Sarah Brightman was originally going to fly on as a tourist — before she backed out or was rejected by the Russians as a unqualified. Instead, it carries one Russian who is going to take over as commander of the station for a long term mission, and two short term astronauts, from Kazakhstan and Denmark, who will remain in orbit for only about 10 days.

They are taking the long, two-day rendezvous route to ISS, so they won’t actually dock until Friday.

What it was like practicing Islam for the first Malaysian in space

8:57 am

This article, describing the 2007 flight of the first Malaysian in space, launched as a passenger in a Russian Soyuz capsule, is mostly worth reading because it goes into details on the Islamic religious rules the astronaut had to follow to practice the religion in space.

Muszaphar had to spend time going through an instruction manual on daily religious rituals provided by Malaysian mullahs. Vyacheslav Urlyapov of the Moscow-based Centre for Southeast Asia, Australia, and Oceania Studies, RAS Institute of Oriental Studies, sums up the cosmonaut’s experience: “The 11-day flight overlapped in part the holy month of Ramadan. Muslims had been in orbit before him, but it fell to Muszaphar to comply with the detailed instructions written for him by Islamic theologians (ulema) to remain a true believer in space, too.”

Muslims are required to face in the general direction of the city of Mecca while saying the mandatory – five times a day – prayers. But locating the tiny city from space is not an easy task, especially when you are hurtling around Earth at more than 17,000 km per hour. Also, in space there is no sense of direction – as we know it on land. The Malaysian cosmonaut was therefore all at sea during his first space flight.

Mercifully, Muszaphar was released from fasting, and was allowed to say shorter prayers and perform daily rituals according to Kazakhstan time. Plus, he didn’t have to face the constant ordeal of locating Mecca.

Kind of describes the problems when a medieval religion is thrust into the 21st century. The medieval religion has to change.

Whiskey in space!

9:25 am

An experiment to test how whiskey ages in weightlessness is about to begin on ISS.

H-II Transfer Vehicle No. 5, commonly known as “Kounotori5” or HTV5, was launched on Wednesday from JAXA’s Tanegashima Space Center carrying alcohol beverages produced by Suntory to the Japanese Experiment Module aboard the International Space Station, where experiments on the “development of mellowness” will be conducted for a period of about one year in Group 1 and for two or more years (undecided) in Group 2.

Don’t worry, the astronauts on ISS won’t be getting drunk. After the test period is complete the samples will then returned to Earth, untasted, where they will then be compared with control samples.

Orbital ATK cargo contract extended

4:56 pm

The competition heats up: NASA has ordered two more cargo flights from Orbital ATK.

Orbital ATK, Dulles, Virginia, will fly two more missions under its 2008 contract for a total of 10 flights, according to Orbital ATK spokeswoman Vicki Cox. The company designated the missions OA-9e and OA-10e, Cox said. She declined to say when those flights will occur, although the company has said it plans to launch any new CRS missions it gets from NASA on Antares once it completes two deliveries using United Launch Alliance’s Atlas 5 rocket. The Atlas 5 launches are slated for December and early 2016 from Cape Canaveral, Florida.

NASA may also order additional cargo flights from its other CRS contractor, SpaceX of Hawthorne, California. “A modification is in work with both [CRS] providers,” NASA spokeswoman Stephanie Schierholz wrote in an Aug. 13 email. “Additional missions for SpaceX are still under discussion.”

That this contract extension occurs about the same time NASA decided to delay its decision on the second round of cargo contracts is probably not a coincidence. It suggests to me that the agency is probably seriously considering awarding one of the next contracts to a more risky proposal, such as Sierra Nevada’s Dream Chaser. In that case, extending the present contracts gives them some additional margin should the new contractors have problems.
