esaoperations: After 1554 days of spaceflight, @Planck yesterday departed its orbit around L2. New trajectory ensures no encounter w/Earth for 300 yrs
え！？

Planck: I'm Leaving orbit around L2, and won't be back in the vicinity for a few hundred years. Cheerio all!
Planck: It was fun while it lasted :-( RT @esascience: On 23 Oct, @Planck will be turned off, completing its 4 year successful mission.
