Atmospheric Structure Investigation Accelerometers

NSSDCA ID: 2005-029A-08

Mission Name: Mars Reconnaissance Orbiter
Principal Investigator:Dr. Gerald M. Keating


The Atmospheric Structure Investigation Accelerometers are engineering accelerometers mounted on the Mars Reconnaissance Orbiter. During aerobraking, these accelerometers will record the drag on the spacecraft, giving information on the density at the spacecraft altitude. This will provide information on the structure of the upper atmosphere and coupling between the upper and lower atmosphere.
