For NASA's InSight Mars Lander, All Systems Are Go for Monday Touchdown

This is the first probe focused on gathering data on the interior of Mars and looking for evidence of seismic activity. It's also the first Mars mission and first mission outside of Earth orbit using tiny cube satellites. These are two satellites the size of a suitcase that will transmit data from Insight back to Earth.
