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 starts today – Update 17:00CEST

UPDATE 17:00CEST Adam writes: Since the atmosphere is not as dense as was feared, we are planning a small manoeuvre next week to further lower the pericentre altitude by between 2 and 3 km. This combined with...
