The Huygens probe is an atmospheric probe designed to make in situ observations of the Saturnian satellite Titan. ESA's contribution to the Cassini mission, Huygens' objectives are to: (1) determine the physical characteristics (density, pressure, temperature, etc.) of Titan's atmosphere as a function of height; (2) measure the abundance of atmospheric constituents; (3) investigate the atmosphere's chemistry and photochemistry, especially with regard to organic molecules and the formation and composition of aerosols; (4) characterize the meteorology of Titan, particularly with respect to cloud physics, lightning discharges, and general circulation; and, (5) examine the physical state, topography, and composition of the surface. Similar in design to the Galileo probe, Huygens is a 1.3 m diameter descent module with a spherical nose and a conical aft section. A thermal protection aeroshell surrounds the descent module, decelerating it from 6 Km/s at arrival to 400 m/s in about two minutes and protecting it from the intense heat of entry. A parachute will then be deployed and the aeroshell jettisoned. The probe will float down through the atmosphere making measurements. Instrumentation for the probe will include: an aerosol collector and pyrolyzer, a descent imager and spectral radiometer, a Doppler wind experiment, a gas chromatograph/mass spectrometer, an atmospheric structure instrument, and a surface science package.
