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.

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

Since arriving at Mars in October 2016, the ExoMars Trace Gas Orbiter has been aerobraking its way into a close orbit of the Red Planet by using the top of t Mars-GRAM 2000: A Mars atmospheric model for engineering applications Advances in Space Research, Vol. 29, No. 2 Application of Accelerometer Data to Mars Global Surveyor Aerobraking Operations 2020-08-23 Other articles where Aerobraking is discussed: Mars Global Surveyor: …employed a technique known as aerobraking—using the drag of the Martian upper atmosphere on the spacecraft to slow it down gradually—to achieve a final 400-km (250-mile) circular polar orbit in which it circled Mars 12 times a day. This orbital configuration allowed the spacecraft to collect data from the entire… In 1997, Mars Global Surveyor demonstrated the feasibility and Mars 2001 Odyssey completed a nearly trouble free aerobraking phase in January 2002. In 2006, Mars Reconnaissance Orbiter will also utilize aerobraking. From the flight operations standpoint, however, aerobraking is labor intensive and high risk due to the large density variability This paper details the aerobraking navigation operation strategy and flight results. It also describes the aerobraking key requirements and navigation challenges. After a seven-month interplanetary cruise, the Mars Reconnaissance Orbiter arrived at Mars and executed a 1.0 km/s Mars … Aerobraking has become a proven approach for orbital missions at Mars.

Mars ballistic capture orbits that neglect the  Aerobraking. Aerobraking began after Mars Orbit Insertion and a check of spacecraft health. It lasted about six months.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Aerobraking has become a proven approach for orbital missions at Mars. A launch of a 1000 kg class spacecraft on a Delta class booster saves 90% of the post-MOI fuel otherwise required to circularize the orbit. In 1997, Mars Global Surveyor demonstrated the feasibility and Mars 2001 Odyssey completed a nearly trouble 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.

A launch of a 1000 kg class spacecraft on a Delta class booster saves 90% of the 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.

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. It will help determine the adequacy of the Odyssey team's aerobraking plans and ensure their assumptions about Mars' atmosphere.
