The InSights mission objective is to place a stationary lander equipped with a seismometer and heat transfer probe on the surface of Mars to study the planet’s early geological evolution. By studying the size, thickness, density, and overall structure of Mars’ core, mantle, and crust, as well as the rate at which heat escapes from the planet’s interior, InSight will provide a glimpse into the evolutionary processes of all of the rocky planets in the inner Solar System.

NASA has been testing its next March-craft InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) and it is now ready to start its journey to Mars sometime in May next year.


InSight was scheduled for launch last year, but then NASA was forced to postpone the launch due to problems with one of InSight’s seismological instruments. Now, however, everything seems to be on track and if everything goes well, InSight will land on Mars in November 2018.
