Probe Descent:
This graphic illustrates the Huygens probe descent profile, beginning with the initial encounter with Titan’s atmosphere and subsequent deceleration. As the probe slows, a small parachute is released, which deploys the main probe parachute. Once the parachute is fully open. the decelerator shield is jettisoned and the probe drills toward Titan’s surface. About 40 kilometers (25 miles) above the surface the main parachute is jettisoned and a smaller drogue chute carries the probe the remaining distance. Science data are continuously being transmitted by the probe to the orbiter during the probe’s 2.5-hour descent to the surface, for later relay to Earth. If the probe survives its impact at approximately 5 meters per second, a small science package will collect up to 30 minutes of post-impact science data to the orbiter. P-50715
