NASA’s InSight Mars lander will gaze (and drill) into the depths of the Red Planet

NASA's latest mission to Mars, InSight, is set to launch early Saturday morning in pursuit of a number of historic firsts in space travel and planetology. The lander's instruments will probe the surface of the planet and monitor its seismic activity with unprecedented precision, while a pair of diminutive CubeSats riding shotgun will test the viability of tiny spacecraft for interplanetary travel.
