Russia Will Send Life to Phobos
How ironic. Not content with searching for life on Mars, the Russian space agency and the US-based Planetary Society will soon be sending terrestrial
life to the Martian moon Phobos. The mini-interplanetary travellers will consist of bacteria, spores, seeds, crustaceans, insects and fungi. Why? To
see how biological life, in various forms, deals with space travel spanning three years.
So if you thought that a human (or monkey) would be the first of Earth‘s ambassadors to land on Mars or one of its moons, you’d be very
mistaken…
The mosquito was a part of the Biorisk project, and the scientists knew the insect had the ability to drop into a “suspended animation” during
times of draught in Africa. The African mosquito can turn its bodily water into tricallosa sugar, slowing its functions nearly to a stop. When the
rain returns, the crystallised creature is rehydrated and it can carry on its lifecycle. The Biorisk mosquito however survived 18 months with no
sustenance, exposed to temperatures ranging from -150°C to +60°C. When returned to Earth, Russian scientists gave the hardy mozzie a health check,
declaring:
Was this insect cruelty of the most extreme kind, or did it serve a purpose? Actually, the mosquito experiment provided an insight to a biological
specimen after being exposed to cosmic rays for long periods, and it also showed us that the African mosquito’s natural ability to slip into a
defensive coma, only to be revived and appear to be healthy (that is, if it was more than just its feet moving – there was no indication as to
whether the little guy was successfully re-integrated into mosquito society). Perhaps the lessons learned from this small test may go to some way of
helping us realise the potential for putting future interplanetary astronauts into some kind of biological stasis.
So that’s the idea behind sending creatures into space: we need to understand how animals and plants deal with space travel. This will aid the
understanding of how humans will cope in space for long periods, plus we need to understand if there are any harmful effects from growing foodstuffs
away from our planet. This is why the Russian space agency wants to go one step further when it launches its Phobos-Grunt mission next year, to send
biological specimens on a voyage of a lifetime. A return trip to the Martian moon Phobos.
Russia on the other hand has far loftier goals; the space agency will attach a small petting zoo. Inside the Russian experiment will include
crustaceans, mosquito larvae (already proven to be enthusiastic space travellers), bacteria and fungi. The Russian experiment will specifically look
at how cosmic radiation can effect these different types of life during an interplanetary trip (essential ahead of any manned attempt to the Red
Planet).
Naturally, there are some concerns about contamination to the moon (if Phobos-Grunt doesn’t do the “return” part of the mission), but the
chances of any extraterrestrial life being harboured on this tiny piece of airless rock are low. Having said that, we just don’t know, so the
mission scientists will have to be very careful to ensure containment. Besides, there’s something unsettling about infecting an alien world with our
bacteria before we’ve even had the chance to get there ourselves…
Say hello to our interplanetary ambassador, the tardigrade (FUNCRYPTA)
A monkey may be sent to Mars, under plans unveiled by Russian scientists.
Although the ape will be looked after by a robot on the mission, the decision is expected to spark controversy with animal rights groups.
The Russians first succeeded in putting monkeys into orbit in 1983.
“We have plans to return to space,” said Zurab Mikvabia, director of the Institute of Experimental Pathology and Therapy in Georgia which supplied
apes for the programme in the 1980s.
The Institute is in preliminary talks with Russia's Cosmonautics Academy about preparing monkeys for a simulated Mars mission that could lay the
groundwork for sending an ape to the Red Planet, he said.
Such an initiative would build on Mars-500, a joint Russian-European project that saw six human volunteers confined in a capsule in Moscow for 120
days earlier this year to simulate a Mars mission.
Mr Mikvabia said: "Earlier this programme was aimed at sending cosmonauts, people (to Mars).
"But given the length of the flight to Mars, and given the cosmic rays for which we don't have adequate protection over such a long trip,
discussions have focused recently on sending an ape instead of a person."
Estimates for the length of the journey to Mars vary depending on the type of mission envisioned, but the European Space Agency says its proposal for
a round-trip mission would take 520 days, or about a year and a half.
If Russia pursues the idea of sending monkeys to Mars, Mikvabia's institute could become the site of an enclosed "biosphere" where apes would be
kept for long periods to simulate space flights.
The Institute said a robot would accompany the first primate to Mars to feed and look after the ape.
Mr Mikvabia said: "The robot will feed the monkey, will clean up after it. Our task will be to teach the monkey to co-operate with the robot."
