The [[Phoenix (spacecraft) | Phoenix lander]] spacecraft landed in what is thought to be an ancient ocean bed near the north pole of [[Mars]]. It is the first, and so far the only spacecraft to land successfully in the Martian polar regions. The [[Mars Polar Lander]] was the only other attempt but it crashed. Until 2008, most scientists thought that there was no possibility of liquid water on Mars for any length of time in the current conditions there. However,
==Droplets on its landing legs==
in 2008 through to 2009, droplets were observed on the landing legs of Phoenix.
