Mars Reconnaissance Orbiter is now dipping into the martian atmosphere to adjust its 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
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 has been used successfully for the three most recent Mars-orbiting spacecraft to reduce orbital size from large elliptical to smaller final science orbit. Most recently, aerobraking was applied to the Mars Reconnaissance Orbiter (MRO) from April to August 2006.1,2 During the aerobraking phase, the orbital period of the spacecraft was

That phase will be used as a calibration period so that engineers can understand how the spacecraft behaves in and out of aerobraking. The aerocapture concept was then referred to as aerodynamic braking or “aerobraking”, and was investigated as a potential orbit insertion method for Mars and Venus missions by Repic et al. In modern terminology, aerobraking refers to a different "aeroassist" maneuver and is not to be confused with aerocapture.
The Mars Global Surveyor (MGS) is scheduled to fire its main rocket engine for 22 minutes at 6:17 p.m. PDT and enter a highly elliptical orbit, with a low point 186 miles and a high point 34,800 miles above the surface of Mars. This robot spacecraft is aptly named. Its mission is to undertake a detailed planetwide survey of Mars.
As the orbital energy is reduced, the orbit Two recent missions to Mars have used aerobraking at Mars as a method for decreasing required fuel mass: Mars Global Surveyor (MGS) and Mars Odyssey. Aerobraking is the process of skimming the spacecraft through the planetary atmosphere at periapsis, decreasing its speed and thus lowering apoapsis. This method saves substantially 2019-10-07 furthest away from the planet) to decrease. Because Mars' atmospheric density at aerobraking altitudes (e.g., between 110-150 km) is not well known, a gradual periapsis stepdown has been performed to col-lect enough statistics on its mean state and variability, and to avoid excessive heating of the spacecraft [Keating et al., 1998].
Ny robot på Mars 2021 – 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.
