Keeping up with ExoMars Trace Gas Orbiter
On Friday, 17 November, the flight controllers at ESOC began operations to bring the spacecraft into a new phase of the on-going aerobraking campaign, marking the start of ‘shorter’ orbits. ‘Short’ is considered, somewhat arbitrarily, as when the orbital period … 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

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

Schiaparelli crash investigation finishes
The inquiry into the crash-landing of the ExoMars Schiaparelli module has concluded that conflicting information in the onboard computer caused the descent sequence to end prematurely. The Schiaparelli entry, descent and landing demonstrator module separated from its mothership, the Trace … Continue reading
