InSight Has Safely Landed
On Monday, NASA’s InSight successfully landed on Mars after a 300 million-mile trip from Earth. InSight stands for Interior Exploration using Seismic Investigations, Geodesy, and Heat Transport. The little robot has a 2 Earth-year mission, to learn how the Earth was formed. That will be only one Martian year and 40 Martian days, or sols.
