Aeolus: Wind-mapping space laser is losing power
13 May 2019
Europe's Aeolus satellite was launched last year to gather data to improve weather forecasts, and its observations have unquestionably proved their worth.
However, the laser is now degrading and has already lost half its power.
Engineers plan to switch Aeolus to its back-up light source in June to see what difference this could make.
If the same issues arise, the UK-assembled spacecraft may not be able to complete the minimum three years expected of the mission.
