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.

Skimming an alien atmosphere

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...

The hottest, bumpiest week yet for Venus Express

Venus Express is now in the final week of its aerobraking campaign, and the spacecraft is about as low as it’s going to get. At last pericentre passage, its altitude was only 129.9 km - and this...

Venus Express goes even lower

Update contributed by the VEX team – Ed. Here's the latest plot showing the lowest altitudes reached by Venus Express on each of its aerobraking orbits. Yesterday morning, 2 July, the spacecraft performed another manoeuvre designed to lower...

Hotter and hotter

In the past ten days, we saw the acceleration felt by the spacecraft as it dips into the atmosphere. However, it’s not these accelerations which threaten the spacecraft – instead, it’s the heating of the spacecraft which...

Aerobraking update

Venus Express completed the 38th aerobraking orbit on 25 June with pericentre passage expected to have occurred at 21:37:04z; the spacecraft was in braking mode between 19:59:05z and 21:54:05z. The predicted pericentre height was 132.7 km (the...
