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 surface operations of the InSight mission immediately after it landed on Mars on November26,2018. To position MRO for relay support during InSight Entry, Descent and Landing (EDL), two propulsive maneuvers were performed in August and October 2018. This paper documents the maneuver strategy employed by the MRO Navigation Team to support the InSight EDL sequence.

Mars Reconnaissance Orbiter Navigation Strategy for the ExoMars Schiaparelli EDM Lander Mission
The Mars Reconnaissance Orbiter (MRO) had planned to provide surface relay support for the brief mission of the ExoMars Schiaparelli EDM lander on Mars in October 2016. Launched with the Trace Gas Orbiter (TGO) in March 2016, Schiaparelli and TGO composed the first part of the ExoMars program. To place MRO directly overhead on its third overflight of the Schiaparelli landing site, two propulsive maneuvers were performed starting three months prior to Shiaparelli’s arrival at Mars. This paper documents the maneuver strategy employed by the MRO Navigation Team to support the Schiaparelli overflight campaign.
Mars Reconnaissance Orbiter Navigation Strategy for the Comet Siding Spring Encounter
Comet Siding Spring encountered Mars on October 19, 2014 at a distance of about 140,500 km - the nearest comet flyby of a planet in recorded history. Mars Reconnaissance Orbiter (MRO) was able to detect the comet, gather science data, and capture images of the comet as it approached Mars. To help protect MRO from the incoming comet particles, two propulsive maneuvers were performed to position the spacecraft behind Mars at the arrival time of the expected peak particle fluency. This paper documents the strategy that the MRO Navigation Team executed to mitigate risk from the comet particles while allowing scientific observations of the comet flyby.
