Summary

The video presents the NASA InSight mission, which aims to study the deep interior of Mars. It explains the scientific objectives: understanding the formation and differentiation of terrestrial planets by analyzing Mars’ crust, mantle, and core. The mission carries two main instruments: SEIS, a seismometer developed by CNES, and HP3, a heat flow probe from DLR. The video details the landing procedure, similar to the Phoenix mission, and the challenges of the entry, descent, and landing. It also mentions the two MarCO CubeSats that will accompany InSight as a technology demonstration. The video emphasizes that Mars is a ’laboratory’ for studying planetary formation because it has remained relatively unchanged compared to Earth. It concludes with the expected timeline: launch in May 2018, landing on November 26, 2018, and a mission duration of about two Earth years.
