This picture illustrates the Huygens probe
descent profile, beginning with the initial encounter with the
Titan 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 drifts toward Titan's surface. About 40 km 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-hr descent to the surface, for later relay to
Earth. If the probe survives its impact of about 15 mi/hr, a small
science package may transmit up to 30 minutes of post-impact science
data to the orbiter. (P-41101)
