Herschel telescope wakes up! June 14, 2009

Posted by jcconwell in Astronomy, telescopes.

Hershel space  telescope opened its hatch that has protected its sensitive instruments from contamination, allowing  light collected by its  3.5m mirror to enter its supercold instrument chamber, or cryostat, for the first time The observatory’s quest is to study how stars and galaxies form, and how they evolve through cosmic time. The command sent on Sunday to fire two pyrotechnic bolts holding down the hatch was arguably the key moment in the European Space Agency (Esa) mission since the 14 May launch from Earth.
