As Astroscientists, we are going to challenge that claim.]]> 2017-08-11 08:36:48 UTC https://padlet.com/len_halprin/6m5mehtlsc6n/wish/180712721 len_halprin https://padlet.com/len_halprin/6m5mehtlsc6n/wish/180712722 The background image is a 1970s proposal for a large, man-made, slowly-rotating colony located at the L-5 point in space, complete with gardens, trees and rivers, and capable of supporting thousands of inhabitants.]]> 2017-08-11 08:36:48 UTC https://padlet.com/len_halprin/6m5mehtlsc6n/wish/180712722 https://padlet.com/len_halprin/6m5mehtlsc6n/wish/181164411 2017-08-15 22:42:10 UTC https://padlet.com/len_halprin/6m5mehtlsc6n/wish/181164411 https://padlet.com/len_halprin/6m5mehtlsc6n/wish/181165096 2017-08-15 22:52:19 UTC https://padlet.com/len_halprin/6m5mehtlsc6n/wish/181165096 https://padlet.com/len_halprin/6m5mehtlsc6n/wish/181165430 In order to survive the lack of air pressure and the cold, humans will need pressurized and heated habitats, also need a spacesuit whenever they go outside.

There’s some support on the planet itself, as Mars does have some of its own raw materials.
