In Sight missio EDL explained ( Entry, Descent, Landing)

InSight is short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport. The mission is the first outer space explorer to study the inner space of Mars. The lander probes deep beneath the surface of Mars to study the fingerprints of the processes that first formed the rocky planets of our solar system. Entry, descent, and landing (EDL) begins when the spacecraft reaches the Martian atmosphere, about 80 miles (about 128 kilometers) above the surface, and ends with the lander safe and sound on the surface of Mars six minutes later.
