Mars-500 ESA cosmonauts

“ ‘Cosmonauts’ ready for Mars test”, BBC, 22/3. The European Mars-500 candidates are briefly profiled, along with an overview of the experiment. See also the related thread at NASAspaceflight.com, where the European astronauts were presented at a press conference at ESA’s European Space Research and Technology Centre in Noordwijk, the Netherlands on 22/3 – also reported at the ESA Mars-500 site, “To Mars and back – as real as it gets”..

Kazakhstan hindering Russian space missions: official”, Space Daily, 27/2. Kazakhstan officials being difficult because they can (and there is probably some payback for the USSR period). I think they will eventually make a bid to take over Baikonur. Hence the need for the new launch complex at Восточный, Vostochnyi (“Eastern”) in the Amurskaya region. Another thread at NSF.com shows ground reservation maps for Vostochnyi.

Soyuz TMA-16 landed

Expedition 22 (Maksim Suraev & Jeffrey Williams) landed on 18/3. Maksim was the first Russian space blogger, and his informal entries proved very popular with the public.

Roskosmos chief Anatolii Perminov said at the traditional meeting for the Soyuz TMA-18 crew on 19/3 that the financial crisis had not affected the process of preparing the cosmonauts for flight.

Some items from NK843:

Russia could possibly increase the number of yearly Soyuz manned spacecraft launches from 4 to 5 from 2012 onwards, because of the timing of the construction cycle that takes 2.5 years. The fifth would carry a space tourist. Since 2009, Russia has doubled the number of launches from 2 to 4 to service the ISS with an increased crew of 6; space tourist flights were thus suspended in 2010. Two Indian cosmonauts will make an orbital flight on one of the extra ships in the 2013-2015 period, according to an agreement reached recently between Russia and India. The chief of Enerigya, Vitalii Lopota, said that a fifth Soyuz could possibly be constructed in 2010 to carry a tourist, possibly in mid-year.

Academican Lev Zelenyi (Лев Зеленый) of the Russian Academy of Sciences said that Russian scientists are not satisfied by the small quantity of the research experiments implemented on the International Space Station (only 2 or 3 out of 500 experiments proposed). Most experiments carried out are technological rather than pure science (one of the latter being “Plasma Crystal”). Despite his misgivings, though, his own opinion of the ISS has become more positive.

“In the beginning I was a complete opponent of the ISS, considering that it was a waste of time and resources. Why? It was the 90s, in space no nothing, space science ceased existence under Yeltsin. We started to put our scientific instruments on Western machines, and ISS absorbed most funding. This was done not in the name of science, but for the sake of political prestige. But now it is possible to assess what happened, not to look guilty or innocent, and to perceive what become a reality. ISS made it possible to preserve the ‘human face’ of our space program, and that its merit. It is certainly important in developing space medicine. Americans in this area have we learn something. And if we start talking, and then carry out a manned flight to Mars, some experience on the ISS will certainly be in demand and useful. Over the past years, we have much lost in space, but the experience of long flights is still preserved,” concluded the Academican.

Two women will be part of the second generation Chinese spaceflight group (along with 5 men), selected from a shortlist of 15. They are all aged between 27 and 34, are qualified to fly fighter jets, and all must be married mothers. (Guardian, Space Daily)

Xu Xianrong, an expert at the air force general hospital, said women had advantages as astronauts over men because they were more mentally stable, better able to bear loneliness and had better communication skills. The insistence that they should also be wives and mothers does not relate to their multi-tasking abilities. Officials are concerned that space flight might affect their fertility. “It’s out of the consideration of being responsible for the female pilots,” Xu told the state news agency Xinhua. “Though there is little evidence on how the space experience will affect the female constitution, we have to be extra cautious. After all, it’s unprecedented in China.”

They seem to be a bit more enlightened than Russia regarding women in space! (See 16/10/2007 entry.)

China is to launch the 1st unmanned experimental module of a planned space station next year (2011). It is an 8.5 ton (7.7 tonne) module, named Tiangong-1, or “Heavenly Palace”, and is to be first used for docking practice by the Shenzhou spacecraft – an unmanned Shenzhou-8 in 2013 – then manned -9 & -10 flights.

Mars-500 food taste testing

IMBP has the news of the candidate shortlist posted on their website, and a group photo.

Mars-500 candidates

The candidates also had to do food taste testing (not an onerous chore!) for the prepackaged food they will need to take on board for 520 days (nearly 1½ years). There won’t be any fresh fruit or vegetables (unless they manage to grow these in a greenhouse).

Doctor Alexandr Agureev (head of the department of nutrition in IBMP and the head of works on nutrition in “Mars-500” project) informed the investigators about the fact that in the given experiment for each stage of the experiment its own variant of food ration would be used:

  1. The stage of simulation of the flight to Mars. The ration is formed from the products (including semi-finished products of dishes), manufactured by a series of European firms («Apetito», «Kellogg», «Hipp», «Coppenrath», «Enervit», «Knorr»). This part of the ration is supervised by German scientist Doctor Jens Titze from the University in Erlangen.
  2. The stage of landing to Mars. The second variant of the ration will have 2 kinds. For the three crew members who will simulate descent and going to the Martian surface, the food ration will be formed from the products ready for consumption without heating and it will only foresee consumption of hot drinks. For these purposes real space products used during forming of food ration for the crews of transportation vehicle “Soyuz” are most suitable. The rest three crew members who will simulate flight on the Martian orbit, will eat the ration of the first and third variants.
  3. The most difficult task is forming of the 3rd variant of food ration for the stage of simulation of the flight from Mars to Earth. It is connected with the fact that the main mass of products for cosmonauts has shelf life in temperature conditions of the environment from 1 to 2 years. However, assortment of products having 2-year shelf life is extremely limited.

In 520-day experiment this food ration will be formed from products produced by food enterprises of Korea, Italy, China and Russian (“Gala-Gala” firm and enterprises of food industry Michurinsk city).

I think I will be feeling more interested in Mars-500 than the real manned space program, which is currently limited to a few people going up to the ISS, staying a few months, going down, etc. It has been suggested that an ISS crew member stay up there for a year or more (as cosmonaut Valerii Polyakov did on Mir for 437 days during 1994-1995), but nothing has come of that so far.

The estimated cost of the project is €15 million (around $20.5 million U.S. dollars). I really wish that could have been put toward a real Mars mission. My own (quasi-suicidal) plan is for a manned test mission to Mars and back, orbiting the planet without landing (thus the extra expense for a Mars lander would not yet be needed). The crew would be a minimal two, and the spaceship would be based on the structure of the ISS Russian segment, with a “Topaz” nuclear reactor in an extra rear module to provide power for electrical propulsion (solar power is not enough that far out to Mars). As the mission is experimental, the crew would need to accept the inherent risks (will the life support systems function for that long? Will they survive the effects of background radiation exposure?). Maybe Russia and China could team up to do such a mission. This mission could pave the way for a more expensive manned landing. It would also excite public interest, especially with the risks involved.
