Huygens descent sequence

The main events of the entry and descent of Huygens in Titan's atmosphere. The initial event (To, explosively firing a small deployment parachute), is triggered by accelerometers detecting the entry deceleration. That detection function is activated by a timer unit running for the 22 days since separation from Cassini. [Image Date: 1997-00-00] [97.06.001-005]
