    7676release each panel by software command in orbit.

     78The thermal control of the spacecraft is intended to be passive as far as possible. The sun-pointing attitude
     79results however in a considerable thermal gradient through the spacecraft, making as such a completely
     80passive thermal control difficult to achieve and heaters are foreseen to control the battery temperature. Heaters
     81are also required to de-contaminate specific parts of the solar observation instruments. The SWAP instrument
     82(see below) has a radiator mounted on the side of the spacecraft in order to keep the detector as cold as
     83possible.
