This image provided by NASA shows an artist rendition of the proposed InSight (Interior exploration using Seismic Investigations, Geodesy and Heat Transport) Lander. After driving all around Mars with four rovers, NASA wants to look deep into the guts of the red planet. The space agency decided Monday, Aug. 20, 2012, to launch a relatively low-cost robotic lander in 2016 to check out what makes the Martian core so different from Earth's. NASA's Discovery program picked a project called Insight over missions to a Saturn moon and a comet, drawing complaints from scientists who study other places in our solar system that NASA is too focused on Mars.
