 the stowed condition by the hold-down and release mechanism. This mechanism utilizes thermal knives to
 release each panel by software command in orbit.

+The thermal control of the spacecraft is intended to be passive as far as possible. The sun-pointing attitude
+results however in a considerable thermal gradient through the spacecraft, making as such a completely
+passive thermal control difficult to achieve and heaters are foreseen to control the battery temperature. Heaters
+are also required to de-contaminate specific parts of the solar observation instruments. The SWAP instrument
+(see below) has a radiator mounted on the side of the spacecraft in order to keep the detector as cold as
+possible.
