After a final thruster firing last week to deplete its remaining fuel, ESA's venerable ERS-2 observation satellite has been safely taken out of service. Ground controllers also ensured the space environment was protected for future missions.

The mission ended on 5 September, after the satellite's average altitude had already been lowered from 785 km to about 573 km. At this height, the risk of collision with other satellites or space debris is greatly reduced.
