98%

Where does this value come from? -- Rfc 18:58, 1 December 2009 (UTC)

If one designs a pressure vessel to contain 0.5 atmospheres pressure, as might be adequate for a greenhouse, then the atmospheric pressure of Mars, 0.01 atmospheres helps to hold that pressure in so that the differential pressure is 0.49 atmospheres, or 98% of differential pressure for building such a greenhouse in a vacuum. Of course if one wants to maintain 1 atmosphere internal pressure, then the differential pressure on Mars would be 0.99 atmospheres.--Farred 07:01, 4 December 2009 (UTC)

The Eden Project is a really cool day out but I'm not convinced of the relevance to Mars exploration. It doesn't make reference to anything off-world, or even contained biospheres (in the way Biosphere 2 did). I would suggest that this page should be deleted.--Pete9804 20:01, 28 September 2013 (UTC)
