The ENVISAT ASAR instrument is currently unavailable until further notice following an on-board anomaly on 12-May-03 00:00. An investigation team (ESA-industry) is working on the anomaly with the objective to resume the instrument operations as soon as possible. Check this page for updates as to when ASAR operations will resume.
The payload interruption is confirmed to take place between 18 May and 21 May. All instruments will be switched down on 18 May (4:45 UTC). After an out-of-plane manoeuvre and on-board software changes, the instruments will be gradually switched on starting on 20 May. The mission will be fully operational on 21 May. The operational use of Artemis relay is now planned for end June.

The Envisat payload will be switched off approximatelly from orbit 3752 (18/11/2002 04:33) until orbit 3789 (20/11/2002 18:35), as part of the preventive measures taken to minimize the risk of collition during the Leonids Meteor Shower. As the timining of the meteor shower peaks may change, the period of unavailability may be slightly modified accordingly.
