After 10 years of service, Envisat has stopped sending data to Earth. ESA’s mission control is working to re-establish contact with the satellite.
Although this landmark mission has been in orbit twice as long as it was designed for, ESA hopes to keep the satellite in service until the launch of the successor Sentinel missions.
The first sign that there was a problem came on 8 April when contact with the satellite was unexpectedly lost, preventing the reception of any data as it passed over the Kiruna ground station in Sweden.
ESA’s mission control team declared a spacecraft emergency and immediately called for support from additional ESA tracking stations around the world. A team of operations and flight dynamics specialists and engineers was quickly assembled.
In a concerted effort, the recovery team, which included experts from industry, spent the next days trying to re-establish communications with the satellite.
While it is known that Envisat remains in a stable orbit around Earth, efforts to resume contact with the satellite have, so far, not been successful.
