Mars Landers & Rovers, InSight Lander

The Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) was a NASA Discovery Program mission that placed a single geophysical lander on Mars to study its deep interior.

But InSight was more than a Mars mission. It addressed one of the most fundamental issues of planetary science: understanding the processes that shaped the rocky planets of the inner solar system (including Earth) more than four billion years ago.

Launched May 5, 2018

The mission ended in December 2022 after more than four years of collecting unique science on Mars.
