NASA launches InSight spacecraft to Mars to dig down deep

May 06, 2018

A robotic geologist armed with a hammer and quake monitor rocketed toward Mars on Saturday, aiming to land on the red planet and explore its mysterious insides. InSight will dig deeper into Mars than ever before -- nearly 16 feet, or 5 meters -- to take the planet's temperature. It will also attempt to make the first measurements of marsquakes, using a high-tech seismometer placed directly on the Martian surface.
