How long does a Ground Survey take?
My team has been on Mars for several years now and have neither found new deposits, nor said there's nothing to be found.
Does the team still work when there are less than five people? I had reassigned a two of the geologists through the Leaders screen and later rebuilt the team with two naval officers. The latter were on earth, the original three on Mars. Their location was updated to Mars without me shipping them there, though.
