Mars Lander Moves Rock to Study What's Beneath
NASA's Phoenix Mars Lander slid a rock into a nearby trench Monday to gain access to the soil under the rock.
-
NASA's Phoenix Lander Might Peek Under a Rock
If the robotic arm on NASA's Phoenix Mars Lander can nudge a rock aside today, scientists on the Phoenix team would like to see what's underneath.
