That's it, after some time in the dark, ESA declares end of mission for Envisat.
From the ESA: "Just weeks after celebrating its tenth year in orbit, communication with the Envisat satellite was suddenly lost on 8 April. Following rigorous attempts to re-establish contact and the investigation of failure scenarios, the end of the mission is being declared. A team of engineers has spent the last month attempting to regain control of Envisat, investigating possible reasons for the problem. Despite continuous commands sent from a widespread network of ground stations, there has been no reaction yet from the satellite."

Via the AGISRS mailing list I learned about today's announcement that Envisat is having problems and services are interrupted.
From the ESA announcement: " 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 ESA just announced the release of the global land cover dataset GlobCover 2009.
From the official source: "The GlobCover project has developed a service capable of delivering global composites and land cover maps using as input observations from the 300m MERIS sensor on board the ENVISAT satellite mission. Currently, ESA makes available a set of products covering 2 periods: December 2004 - June 2006 and January - December 2009. [...] The GlobCover composites are derived from the pre-processing module of GlobCover, which includes a set of corrections as cloud detection, atmospheric correction, geolocalisation and re-mapping. The GlobCover Land Cover map is compatible with the UN Land Cover Classification System (LCCS)."
We mentioned the GlobCover dataset quite a few times in the past.
