Europe's Earth observation satellite falls silent

Posted:

PARIS (AP) -- The European Space Agency says it has lost contact with its Earth observation satellite Envisat.

Efforts to resume communications have been unsuccessful since it fell silent April 8.

ESA said Thursday that Envisat remains in a stable orbit around Earth and scientists are still trying to re-establish contact with what it called "the world's most complex Earth observation satellite."

Envisat was launched in 2002 to provide information on land, oceans, ice and the atmosphere. It has long exceeded its expected life span of five years.

ESA had hoped to keep the satellite going until the first of a new generation of Earth observation satellites called Sentinel is launched next year.
