MAVEN webinar: Getting cozy with Mars
The MAVEN spacecraft has successfully completed an aerobraking campaign, lowering the highest altitude of the satellite’s orbit to better transmit data from present and future Martian rovers and landers, while continuing its observations of the Martian atmosphere. In this MAVEN … Continue reading

MAVEN: Aerobraking to lower the orbit
The MAVEN spacecraft today [March 7] performed an aerobraking maneuver (with a 0.2 m/s ∆V) to decrease the periapsis, or lowest, altitude by 1.2 km. MAVEN’s periapsis altitude is now 125.5 km above the surface of Mars and the apoapsis, … Continue reading

MAVEN: Shrinking its orbit to prepare for Mars 2020 rover
The 4-year-old atmosphere-sniffing MAVEN mission is embarking on a new campaign today to tighten its orbit around Mars. The operation will reduce the highest point of the MAVEN spacecraft’s elliptical orbit from 3,850 to 2,800 miles (6,200 to 4,500 kilometers) … Continue reading

Trace Gas Orbiter: Aerobraking down, down
Spacecraft Operations Engineer Armelle Hubault, working on the ExoMars TGO flight control team, reports: This graphic (above) gives a very concise visualisation of the fantastic progress we’ve made with aerobraking to date. It was coded by my ExoMars TGO colleague … Continue reading

Trace Gas Orbiter: Crossing Phobos’ orbit while aerobraking
[Editor’s note: See update.] Here are the facts about the Phobos orbit crossing today [November 16]. The orbit crossing is not a Phobos flyby. In fact, we did our best to ensure that Phobos would be at the farthest possible … Continue reading

ExoMars aerobraking becomes too severe; shifts automatically to higher orbit
ExoMars has successfully performed a Flux Reduction Manoeuvre (FRM) for the first time. The manoeuvre was triggered by the excessive density of Mars’ atmosphere, which had slowed the spacecraft above the limit the operations team normally allows. The manoeuvre happened … Continue reading

ExoMars TGO: Aerobraking restarts in September
After an approximately 11-week pause due to Mars conjunction and a major software update, ESA’s ExoMars Trace Gas Orbiter (TGO) will restart its aerobraking campaign in September. Aerobraking, you’ll recall, is the year-long campaign being conducted by TGO using the … Continue reading

Trace Gas Orbiter: Aerobraking suspended
On 25 June, the Trace Gas Orbiter (TGO) will suspend its aerobraking campaign until the end of August due to Mars’ conjunction with the Sun. With Mars behind the Sun, TGO’s communication with Earth will be difficult, and so the spacecraft orbit … Continue reading
