I missed the 2 year anniversary of launch on 14th May, but a colleague has just sent me this, reminding me of the day when the first instrument on Herschel was turned on…
Exactly two years ago (on 19th May 2009), the first scientific instrument on
Herschel was successfully switched on. Since then, Herschel has been restlessly
producing fantastic and astonishing results which can even be downloaded directly to your iPhone/iPad!
It’s been an astounding ride since then, and it just keeps getting more and more interesting!
