MARS RECONNAISSANCE ORBITER NAVIGATION STRATEGY FOR SUPPORT OF INSIGHT LANDER'S ENTRY, DESCENT AND LANDING SEQUENCE

The Mars Reconnaissance Orbiter (MRO) provided primary relay support for the InSight mission's Entry, Descent and Landing (EDL) on November 26, 2018. To position MRO for relay support during InSight EDL, two propulsive maneuvers were performed: the first on August 22, 2018 and the second on October 24, 2018. This paper documents the phasing strategy employed by the MRO Navigation Team to support the InSight EDL sequence.
