A crowd of people representing ESA, the three Herschel instrument teams, and industry assembled in the main control room in ESOC (Darmstadt, germany), while Herschel spacecraft operations were terminated on 17 June 2013.

At about 12:25 UT, as Herschel's thrusters had run out of hydrazine, the last telecommand was sent to the spacecraft by manual commanding, causing it to turn itself off. In the picture above (left) Göran Pilbratt and Micha Schmidt (right) look over the shoulders of one of the spacecraft controllers, watching the pressure in the thruster tanks gradually go down.
