GOCE stands for ""Gravity Field and Steady-State Ocean Circulation Explorer"" - a scientific ESA satellite to be launched in 2006 that will measure the Earth's gravity field with unprecedented accuracy. Gravity is not the same at all places on Earth, and accurately determining its value everywhere is only possible from space. Gravity data matters for surveying and geodesy, and in studies of Earth interior processes, ocean circulation, ice motion and sea-level change.
This programme includes new 3-D graphics of GOCE, location recordings of the Structural Model of the satellite during testing at ESTEC, in June 2004, and soundbites by Danilo Muzi, GOCE Project manager, and Mark Drinkwater, GOCE Project Scientist.
The programme includes an A-roll of five minutes (split audio - English voiceover) and a B-roll of 8 minutes with clean international sound.

When we think of gravity we think of it literally as the force that keeps our feet
on the ground. Although itÕs invisible, it provides us with a sense of the
horizontal and vertical. Most of us take the EarthÕs constant pull of gravity for
granted.

But if studied in detail gravity on Earth turns out to be more complex than most
people assume.

Gravity is not the same all over the world. It is a force that varies from place to
place on the surface of the planet depending on a number of different factors.
Firstly the distance between the centre of the Earth and itÕs surface is smaller at
the poles than the equator. This flattening is due to the Earths rotation making
the pull of gravity slightly stronger at the poles.

Secondly the surface of the Earth is not even with high mountains and ocean
trenches causing the value of gravity to vary. Thirdly the material composition
inside the Earth varies and matter is not evenly distributed; all of whi
