The nature of aerobraking at Venus provides ideal opportunities to demonstrate aerobraking enhancements and techniques yet to be used at Mars, such as flying a temperature corridor (versus a heat-rate corridor) and using a thermal-response surface algorithm and autonomous aerobraking, shifting many daily ground activities to onboard the spacecraft. Odyssey's aerobraking occurs in three primary phases that engineers call 'walk-in', 'the main phase' and 'walk-out'. The walk-in phase occurs during the first four to eight orbits following Mars arrival. That phase will be used as a calibration period so that engineers can understand how the spacecraft behaves in and out of aerobraking.

In the late 1990s, aerocapture was considered for the Mars Odyssey mission (then referred to as Mars 2001 Surveyor), but was later dropped in favor of aerobraking due to cost reasons and heritage with other Mars missions. In the early 2000s, aerocapture was identified as the focus area by the NASA In-Space Propulsion Technology (ISPT) program.

More recently, aerobraking was used by the Mars Odyssey and Mars Reconnaissance Orbiter spacecraft, in both cases without incident. In 2014, an aerobraking experiment was successfully performed near the end of the mission of the ESA probe Venus Express. Aerobraking in fiction

Aerobraking mars




A method of estimating the Martian neutral atmospheric density at 130 km, and comparison of its results with Mars Global Surveyor and Mars Odyssey aerobraking observations based on the Mars Climate Database outputs. Earth Planet. Phys., 4(4), 408–419doi: 10.26464/epp2020038

Aerobraking is defined as the deceleration resulting from the effects of atmospheric drag on a vehicle; thus, aerobraking eliminates the retropropulsion The Trace Gas Orbiter — part of the European-led ExoMars exploration program — just wrapped up a nearly yearlong "aerobraking" campaign, during which it used the drag from Mars' atmosphere to Aerobraking was to take 6 months and several orbits around Mars to reduce the apoapsis (highest point in orbit) and align the MGS spacecraft in the proper polar orbit. The duration of the aerobraking phase is directly related to how fast Mars' relatively thin atmosphere reduces the spacecraft's velocity. We analyzed X-band radio tracking observations of the Mars Odyssey spacecraft during its aerobraking phase (October 2001–January 2002). Using the precision orbit determination softwareGEODYN,we obtained estimates of the spacecraft orbital energy lost during eachperiapsis pass due to atmospheric drag.Wealso recovered atmospheric density values at each periapsis, assuming simple exponential 1997-10-01 Aerobraking is a spaceflight maneuver that reduces the high point of an elliptical orbit by flying the vehicle through the atmosphere at the low point of the orbit ().The resulting drag slows the spacecraft.Aerobraking is used when a spacecraft requires a low orbit after arriving at a body with an atmosphere, and it requires less fuel than does the direct use of a rocket engine.
