Slice of History - Cassini and Huygens Amicably Separate “After Seven Years of Living Together”
The Huygens Probe successfully detached from the Cassini orbiter on 24 December to begin a three-week journey to Saturn’s moon, Titan. All systems performed as expected and there were no problems reported with the Cassini spacecraft.”
The Huygens probe, built and managed by the European Space Agency (ESA), was bolted to Cassini and had been riding along during the nearly seven-year journey to Saturn, largely in “sleep” mode. Huygens was the first human-made object to explore on-site the unique environment of Titan, whose chemistry was assumed to be very similar to that of early Earth prior to the formation of life. The probe remained dormant until the onboard time “woke it up” just before it reached Titan’s upper atmosphere a few weeks later. The data gathered during its 2.5-hour descent into Titan’s murky atmosphere was transmitted back to Cassini, who relayed the data to JPL, the DSN, and ESA’s Space Operations Center in Darmstadt, Germany.
Seven days after separating, Cassini successfully flew by Saturn’s moon, Iapetus, at a distance of 76,700 mi (123,400 km) on Friday, 31 December, marking the first close encounter of Iapetus during the four-year Cassini tour. CL#23-6610
