Nasa’s newly approved mission to Mars, InSight (Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport), will seek clues to planetary creation. InSight — set to launch in 2016 — could answer questions about Earth’s formation since both planets are classified as terrestrial (rocky), but Mars is less geophysically active and thus has a better preserved early history.
In this video, Mission team members for InSight explain how the spacecraft will advance our knowledge of Mars’ history and rocky planet evolution…
