The INTEGRAL spacecraft

January 5, 2013
Date: 26 Sep 2002 Satellite: INTEGRAL Depicts: Exploded diagram of the INTEGRAL spacecraft Copyright: ESA 2002. Illustration by Medialab. The Integral spacecraft is composed of two main sections, the service module and the payload module. The service module is the lower part of the satellite. It provides essentials such as power (via solar panels), satellite control and the communications link to the ground. The payload module is connected to the service module and consists of the four scientific instruments. To reduce the cost as much as possible, the service module design from ESA's XMM-Newton satellite was reused.
