Wooden spaceship

The Accidental Russophile alerted me to these two interesting articles about the upcoming “Mars-500” long-duration simulation experiment:

Russians Prepare to Go to Mars Without Leaving the Ground”, James Oberg, IEEE Spectrum, September 2007. He visited the simulation complex at the Institute of Medical and Biological Problems. Staying in the simulator for that length of time will be challenging! Like being imprisoned. Once the novelty wears off after about 2 months or so things will start to get “interesting”. Still, I almost wish I could volunteer – I am doing nothing with my life and it wouldn’t be too much different to being in my bedroom – but I am lacking any qualifications whatsoever. (I’d volunteer for a solo Mars mission, though, even if it resulted in my death!) Such an experiment would be bearable if there were Internet access, but unfortunately there isn’t! The crew can only send and receive emails. I’d be having Internet-deprivation withdrawal symptoms after the first week!

The interior of the simulator is constructed with wood – very nice woodwork! – which “is supposed to induce a feeling of cozy hominess”. It does add a warm feeling to the rooms, unlike metal. Couldn’t have wooden décor on a real spaceship though; a fire hazard and too heavy to carry into orbit.

One unresolved problem:

As pieces fall into place, a few unsolved problems stand out in greater relief. Dyomin confesses that one entirely ordinary Earth side process was giving him fits: “We still don’t know what to do with the garbage,” he ruefully admits. Throwing it overboard (as the Russians did on their Salyut and Mir space stations) would cost too much in terms of the air lost with each jettison, and on a real Mars mission it would fill the skies with twinkling garbage bags that would drift for months, confusing stellar navigation sensors and potentially bumping into the ship and fouling exterior mechanisms. Keeping it inside will require strict sanitary isolation. But with decades of long-term human spaceflight experience under their belts, the team will think of something.

In Stephen Baxter’s novel Titan the crew on the journey to Saturn’s moon used this device to dispose of garbage:

She checked the SCWO reactor, the Supercritical Wet Oxidation system. The SCWO was a remarkable piece of gear. Inside, slurry was heated to 480°C and 240 atmospheres, conditions where water went supercritical. It was like liquid steam. If you jetted in oxygen, you could get an open flame, under water. The SCWO would burn anything, any waste they threw into it: crap, urine, food scraps, garbage, mixed up with organic wastes and water. Out came steam, carbon dioxide and a whole bunch of nitrates – compounds of nitrogen they could use in the [hydroponic] farm.

It looked to Benacerraf as if the temperature control inside the reactor had been a little variable. That was a worry; not everything that happened inside that reactor was well understood. The SCWO was a relatively new technology – the reactor and its backup fitted in Discovery were actually upgrades of breadboard prototypes. There were safety concerns around the high temperatures and pressures in the reactor, and corrosion of the pressure chamber. That corrosion could leak metals into the liquid effluent, which could then end up in the food chain.

Russia Prepares for Mars Mission with ‘Big Brother’ Experiment”, Spiegel Online, 14/9. Here is revealed that one of the participants is cosmonaut Sergei Ryazanskii!

Sergei Ryazanskii has already passed all the necessary medical and psychological tests. The athletic, blue-eyed, 32-year-old Russian is testing one of the wooden cots in the mock spacecraft’s sleeping module. His grandfather helped build one of the very first Soviet rockets and two years ago he managed to graduate from Russia’s cosmonaut training program. A romantic attraction to outer space simply runs in the family blood. “My wife was the only one who couldn’t understand that,” Sergei sighs. She divorced him.

From his training, Ryazanskii knows how extreme conditions can affect a person’s psychological well-being. “In total isolation with five people, you’re burdened by five times as many problems, and so are the others,” he says. It’s exactly that sort of group dynamic that the IBMP wants to examine.

Divorced! (They had one child.) That must have been recent. He is only 4 years younger than me. (He had a Livejournal, but seems to have deleted it. His website is still online. Hopefully he will keep an online journal for the experiment?)

Russian space tourist?

Haven’t felt much like posting; just don’t feel much interested, so here is some collected news as remarked on in my other journal.

As-yet unconfirmed reports say that a Russian businessman-politician, Vladimir Gruzdev, looks set to be a space tourist in September 2008 or in 2009. I bet the cosmonauts won’t be happy about that! Especially those who have spent years waiting for their first flight (e.g. Dmitri Kondrat’ev – selected 1997, Oleg Kononenko – selected 1996, Roman Romanenko – selected 1997), only to have someone with loads of money “jump the queue”.

Energiya changed some of the links at their site, so I had to redo most of the links to them on my site (and blog), rather annoyingly! I think they are all working.

Cosmonaut Mikhail Kornienko climbed Mt. Kilimanjaro in Africa!

S.P. Korolev RSC Energia, Korolev, Moscow region. Cosmonaut tester of the S.P. Korolev Rocket and Space Corporation cosmonaut team Mikhail Borisovich Kornienko, upon his return to Moscow after climbing mountain Kilimanjaro (5895 meters high) as a member of a team of three mountaineers, was received by the Head of the Federal Space Agency A.N. Perminov.

M.B. Kornienko accomplished this climb while being on vacation. On the highest peak of Africa he left one copy of the Roskosmos commemorative badge and planted the flag of S.P. Korolev RSC Energia. The second copy of that badge that had been to the top of Kilimanjaro, M.B. Kornienko handed over to the Head of Roskosmos.

A.N. Perminov pointed out the high level of preparedness of the cosmonaut tester for working in extreme conditions, which allowed him, the only one of the whole team, to overcome the difficulties of the climb in its final phase.

Russian Federal Space Agency: Космонавт вышел на «малую» орбиту – покорил Килиманджаро (Cosmonaut has reached a “small” orbit – he conquered Kilimanjaro).

A Russian Proton-M rocket with a Japanese satellite onboard crashed on launch on 9/9.

“Russia To Get A New Space Port”, RIAN/SpaceDaily, 11/9.

On the last day of summer, the Russian Space Agency made a sensational announcement. Its head Anatoly Perminov painted an epic picture of Russia’s immediate future in space, specifically its manned part. A week and a half ago, during a final news conference with journalists at the MAKS-2007 International Air Show, to the surprise of many, he spoke modestly about the evolutionary path to be taken by the space industry. “Our primary objective,” he said, “is to stick to existing reliable systems already used in manned flights.” Evidently they found the air show to be the wrong place to disclose the Agency’s truly revolutionary ambitions.

Female commanders set for landmark mission”, MSNBC.com, 13/9. Two female NASA astronauts will command the ISS (Peggy Whitson) and Space Shuttle (Pamela Melroy, STS-120 Discovery) next month. No Russian woman has been in space since Elena Kondakova in 1997, and none will for a few years yet (assuming the only current female cosmonaut, Elena Serova, successfully completes her candidate training). Russia are now dismayingly far behind in this area.

A Soyuz-U rocket successfully launched yesterday with an unmanned Foton spacecraft carrying various experiments (listed in Russian and English at the FKA site). Some fish and Mongolian gerbils (small rodents) are getting a ride into space as part of the experiments. A space tether experiment will also be performed (James Oberg’s comments about it at FPSpace).

Mice and men: space gerbils blaze trail for humans to Mars”, Space Daily, 14/9. More on the gerbils getting their first and only spaceflight; unfortunately some of the hapless creatures will be dissected after landing. (A brief RIA Novosti news item on the creatures the Foton is carrying.)

From Novosti Kosmonavtiki news №653:

18/9/2007/00:01: Russian manned spacecraft will fly to Mars, possibly in 2020, Aleksandr Kaleri thinks

A Russian spacecraft with the crew aboard will fly to Mars, possibly in 2020. About this stated the chief of the flying space center of company Energiya, airman-cosmonaut Aleksandr Kaleri, at the All-Russian astronomical conference the “Space Boundaries of the 21st Century”, that was opened on 17 September in Kazan. “The flight duration will be two years with a one-month stay on Mars,” noted the cosmonaut. It is assumed that aboard the ship with a weight of up to 600 tons will fly the crew of 4-6 people. To put this ship immediately into orbit is impossible, therefore they will assemble it in orbit from the modules, said Kaleri.

According to him, the dimensions of modules and subsistence maintenance system are developed, the methods of creating the large constructions now are selected: so the length of each of two solar batteries will compose 700 meters. Studies with respect to the guarantee of reliability of flight are conducted. For example, for the protection from the solar radiation it is proposed the walls of crew quarters for the cosmonauts are to be filled with inert gas.

According to the most optimistic forecasts, the flights will begin in 2020, with the most pessimistic beginning in 2025. In the first flight only the circling around the “red planet” will be undertaken. The second flight will carry a full-scale landing module, but also without the embarkation of cosmonauts. And only in the third flight half of the crew will land on the planet, the cosmonaut concluded.
