Jason 2 is on its way. I have already used output from Jason 1 and Poseidon 2 for measurement of sea surface height. As satellites are continually improving the accuracy of the data they output and each mission delivers better data, it was with great interest I read about the next Jason mission.

Alongside this is the important Goce (Gravity field and steady-state Ocean Circulation Explorer) mission, which I'd always thought was spelt Goose until I saw it in writing on day. Doh. It will deliver better results than the Grace mission which has been measuring the earth's gravity field since 2002.

It's a busy world up there in space.
