Green rocket set to go

By Jon Guy, London

ENGINEERS load the top section of the Ariane 5 rocket which is due to send the biggest environmental satellite ever built into orbit in the early hours of tomorrow, writes Jon Guy, London. The rocket is expected to blast off from French Guiana with the Envisat on board at around 7 am GMT and once in orbit the satellite will send a constant stream of data on the planet back to scientists in the UK and Europe.
