I predict it won't happen

Mars mission poses greater risk to human life than Nasa would allow | Science | guardian.co.uk

The Guardian lists all of the technical and other problems that this proposed slingshot missions would face. 

Yet still, it seems not to have made the key point (and I can't say any other report I have noticed has either):   there is no point in sending people on a dangerous mission with untested life support equipment in a tiny can just to spin around a planet, take some photos, and come back.   

This article says the capsule would have a about 7 cubic meters space.  But some articles say the inflatable living quarters part would have a volume of 17 m3.  The pressurised volume of the International Space Station is 837m3.  Skylab, with a crew of 3, had a volume of 368m3.

Spending more than 500 days in a volume of 17 m3 is, in itself, nuts.

Is there a reliable medication available for the sudden development of claustrophobia?

Especially if the inflatable module develops a leak and has to be evacuated?

I read somewhere that the mission won't take pressure suits.  No EVA then to get away from each other for a while.

This is not going to happen...
