Decommissioning

The LISA Pathfinder satellite was shut down this week, after 16 months of service hunting for gravitational waves. But this is only the beginning: the satellite was a testbed for technology that will eventually be used in the main LISA mission, the largest gravitational wave observatory ever built.

Sellafield is Europe's largest nuclear site and although operations including spent fuel management and nuclear waste storage continue on-site, power generation ceased in 2003. As part of the decommissioning process, the site's tallest chimney will now be demolished.
