Herschel: Seeing the world in a different light

Eckhard Sturm Max-Planck Institute for Extraterrestrial Physics Garching, Germany Herschel and Planck – Space Science Talks ESOC / Schloss Braunshardt 19/03/2009 SEEING THE WORLD IN A DIFFERENT LIGHT HERSCHEL-PACS IN A NUTSHELL

The PACS Consortium: 15 Institutes in 6 Countries Herschel-PACS in a Nutshell | Eckhard Sturm | Schloss Braunshardt| Page PACS has been designed and built by a consortium of institutes and university departments from across Europe under the leadership of Principal Investigator Albrecht Poglitsch located at Max-Planck-Institute for Extraterrestrial Physics, Garching, Germany. Consortium members are: Austria: UVIE; Belgium: IMEC, KUL, CSL; France: CEA, OAMP; Germany: MPE, MPIA; Italy: IFSI, OAP/OAT, OAA/CAISMI, LENS, SISSA; Spain: IAC.
