Follow this link to the Parabolic Flight campaign application page and find out. The Foton satellite is derived from the Vostok family of manned capsules as used by Yuri Gagarin. Foton is capable of carrying up to 500 kg of scientific payload. The capsule houses the scientific payload and the landing parachute. It is equipped with three circular hatches, two on opposite sides for payload installation and removal, with a third hatch giving access to the parachute trunk.
Landing is assisted by parachutes and retro-rockets to cushion the impact on the ground.
The service module is 3.2 m long and 2.5 m wide. The attitude control system incorporates nitrogen jets and Earth horizon sensors for alignment of the spacecraft in preparation for its re-entry. Firing the retrorocket reduces the spacecrafts' velocity so that it falls into a lower orbit and re-enters the atmosphere. The service module remains attached to the re-entry capsule by four retaining straps until the retrorocket burn is over. The battery pack is a 1.8 m diameter cylindrical section, capped by domed ends and attached to the re-entry capsule by four legs.
