According to the European Space Agency (ESA) press release:
The first full-duration simulation of a human mission to Mars is about to begin. After closing the hatch, the crew of six will remain in their ‘spacecraft’ for 520 days.
The gist of the project is to simulate what a crew would go through on a flight to Mars. Not how they would operate when they get there to Mars and begin to explore, but how they would operate during the flight itself. Because there is not yet a clearly defined plan for a Mars mission, the simulation can only be quite general in nature. So is there not enough data to be getting on with from International Space Station (ISS) missions, for example? Sure, ISS missions tend to be about six months, rather less than the 500 days being simulated here. But there is no particular reason you would want to take 500 days to get to Mars. Mars Direct, one of the most worthwhile and conceptually robust Mars mission architectures you will find, takes only 6 months to get there. But if you really wanted to know how humans would cope in claustrophobic technological adversity for longer periods, how about looking at submarine crews – there must be decades of data here.
Of more value would be simulating what to do when you get to Mars – how do you explore, what priorities do you have, how do you conduct fieldwork? This is what the Mars Society does in its Mars Analogue Research Stations (which will get a post of their own at some point) – simulates working in and exploring a Mars-like environment. I was delighted to read that Diego Urbina, one of the Mars500 crew members, was actually a Mars Analogue Research Station crew member earlier this year. I am lucky enough to have done the same thing a few years ago (Crew 27 rules!).
My other reservation is that this is not part of an ambitious, clearly defined route to Mars. Sure, ESA have aspirations, but it’s no more than that and you can keep doing this kind of groundwork indefinitely without getting anywhere if you don’t have a sharp deadline.
On the plus side though, I found this statement reassuring:
Whereas research onboard the ISS is essential for answering questions concerning the possible impact of weightlessness, radiation, and other space-specific factors, other aspects such as the affect of long-term isolation and confinement can be more appropriately addressed by the use of ground-based simulations.
If we want to go to Mars, we go to Mars. We don’t need to get expensively waylaid on the Moon “studying” all sorts of things that we could clear up whilst still on Earth. I’m not convinced of the utility of the ISS, but at least here we have a working assumption that we can practice many things on Earth, and then head straight to Mars.
Finally, this made me snigger:
Microbial samples will be taken from all possible reservoirs of microbes.
