Picture of the day
Artist's conception of the
terraforming of Mars
in four stages of development.
Terraforming
is the
hypothetical
process of changing a planet's environment to produce a world that is
habitable by humans
. The globe in the final stage (on the right) is based on data from the
Mars Global Surveyor
. All the shore lines are approximate to where it is believed they would be if all the
permafrost on Mars
melted.
