A quick search on Google Scholar turns up 106 articles published in 2018 using Huygens' data. The Entry Assembly Module carried the equipment to control Huygens after separation from Cassini, and a heat shield that acted as a brake and as thermal protection. Once ENA has done all this, it is jettisoned and releases the DM. Cassini revealed in great detail the true wonders of Saturn, a giant world ruled by raging storms and delicate harmonies of gravity.
Cassini carried a passenger to the Saturn system, the European Huygens probe —the first human-made object to land on a world in the distant outer solar system. The Descent Module contained the scientific instruments and three different parachutes that were deployed in sequence to control Huygens' descent to the surface … The ENA connects Huygens to Cassini until it performs the ejection of the probe. Huygens made only one direct measurement of the speed of the surface wind just before its landing on Titan, and at that time it was very low, less than 1 metre per second. The Huygens module traveled with Cassini until its separation from the probe on December 25, 2004; Huygens landed by parachute on Titan on January 14, 2005. For example, though Voyager 1 is still contactable en route to the heliopause, it is listed as "mission complete" because its primary task of studying Jupiter and Saturn has been accomplished. But when added to accelerometer sensors on Huygens and VLBI tracking of the position of the Huygens probe from Earth, reasonably accurate wind speed and direction measurements could still be derived. When the Huygens probe was being designed more than 10 years ago, it was required that the probe had to be magnetically ‘clean’ when switched off, meaning that any residual permanent magnetic fields must not interfere with the sensitive Cassini magnetometers. Once a probe has reached its first primary target, it is no longer listed as "en route" whether or not further travel is … Ten years ago, the Huygens probe took these images of Saturn's moon Titan at four different altitudes as it descended to the surface. The probe had two parts: the Entry Assembly Module and the Descent Module. So I'd say the data is still being analyzed and used. Once Huygens is ejected, ENA controls its journey to Titan. It also provides thermal protection for the probe during its entry into Titan's atmosphere and the 9 m (or 28 ft) parachute that slows the probe down so it can land safely on Titan. It returned data to Earth for around 90 minutes, using the orbiter as a relay.
