Aerobraking down, down

When TGO skims through the atmosphere, it has to adopt a specific orientation to make sure it stays stable and does not start to spin madly, which would not be optimal.

Keeping up with TGO

On 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.

TGO short summer break

On 25 June, TGO will suspend its aerobraking campaign until the end of August due to Mars' conjunction with the Sun.

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.

Mission controllers are preparing for the ultimate challenge: using drag from the Red Planet’s atmosphere to lower ExoMars/TGO into its final Mars orbit.

Venus Express aerobraking: quick update 18 July

Today’s update on the orbit raising manoeuvres of Venus Express, following the aerobraking campaign, is provided by acting spacecraft operations manager Joerg Fischer: Everything appears nominal so far. We have completed eight orbit correct manoeuvres (OCMs), each raising the...

Venus Express rises again

  After a month surfing in and out of the atmosphere of Venus down to below 130 km from the planet’s surface, Venus Express has embarked on a 15 day climb up to the lofty heights of 460 km. Over...
