NASA’s InSight lander has touched down safely on Mars

NASA’s InSight lander touched down on Mars on November 26 for a study of the Red Planet’s insides. “Touchdown confirmed, InSight is on the surface of Mars!” said Christine Szalai, a spacecraft engineer at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., in a live broadcast from mission control. The lander sent its first picture — which mostly showed the inside of the dust cover on its camera lens — shortly after landing.

 

The landing of InSight, short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, brings the total number of successful NASA Mars landings to eight. InSight touched down at about 2:55 p.m. Eastern time in a wide, flat plain called Elysium Planitia, near Mars’ equator. News of the landing was relayed by a pair of tiny satellites called MarCO that travelled to Mars with InSight as an in-house communications team.

 

Over the next Martian year (about two Earth years), InSight will use a seismometer to listen for “Marsquakes” and other seismic waves rippling through the planet (SN: 5/26/18, p. 13). The lander will also drill five meters into Mars’ surface to measure the planet’s internal heat flow, a sign of how geologically active Mars is today.
