Today the MAVEN probe performed an aerobraking maneuver (with 0.2 m/s ∆V) to lower the periastrum by 1.2 km.
Currently, MAVEN’s periastrum reaches 1125.5 km in altitude and the apogee 5400 km. The density of the Martian atmosphere at apogee is 3.4 kg/km³.
Further maneuvers are planned with the goal of bringing the apogee to 4500 km altitude by the end of April.
