	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.--[[User:Pete9804\|Pete9804]] 20:01, 28 September 2013 (UTC)		The Eden Project is a really cool day out but I'm not convinced of the relevance to Mars exploration.

	: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.--[[User:Farred\|Farred]] 07:01, 4 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.
