Aerobraking: So far, so good

The news from the ExoMars/TGO mission control team following the first ten days of the ‘walk-in’ to aerobraking is good! #hang10

TGO feels the burn

We already have had already two percienter passes at 150 km height; they gave us, respectively, 11 and 10 mm/sec of delta V. All is nominal and working fine for the moment.

Hang 10 over Mars

On 6 April, the craft will begin the critical, year-long ‘aerobraking’ phase, using the faint drag of the very upper reaches of the Martian atmosphere to slow the craft, lowering its orbit.

Update on TGO data relay

The first in-flight data-relay tests were conducted with the NASA rovers in November 2016; these were successful.

Debris manoeuvre abort

Today’s debris avoidance manoeuvre has been cancelled! To recap: Based on an assessment of information on hand as of late yesterday, it was clear that the conjunction – a close flyby – of a ca. 15-cm chunk...

Swarm debris manoeuvre cancelled

Assessment this AM of latest debris object tracking data and Swarm-B orbit indicated conjunction risk has fallen to acceptable levels.
