The Huygens was not capable of transmitting data directly to the Earth, instead Cassini relayed all communication. Therefore mission lifetime was limited by possible communication window from Titan surface to Cassini (which was orbiting Saturn, making only fly-by around Titan and departing the moon soon after the landing). Keeping Huygens alive until Cassini ...

This book has a table with the energy budget for Huygens: Data relay system: 214 Wh Computer: 246 Wh Electric power system: 5 Wh Payload: 325 Wh Losses: 132 Wh Pre-separation checks: 50 Wh Total: 972 Wh for the designed mission: The batteries and all other resources were sized for a Huygens mission duration of 153 minutes, corresponding to a maximum ...

A quick search on Google Scholar turns up 106 articles published in 2018 using Huygens' data. So I'd say the data is still being analyzed and used.

As noted before, landing gear, especially for soft or relatively rough surfaces, tends to be heavy, and mass is at a premium. More on that later. But there is another good reason to stay aloft, especially if the craft can fly at more than ~12 m/s, which is Titan's equatorial rotation speed (11.744 m/s): you can stay on the Earth-facing side of Titan, so you ...

Because if it ever lands, it will never ever take off again. The final sentence of the abstract refers to "gliding into" a lake or flat surface, but another way of describing this would be "crashing". Aeroplanes need a length of ground clear of obstructions to land on. That's not going to happen on Titan, there's nobody there to move the rocks out of the ...

The International Astronomical Union is the most official source on this matter. Among other surface features on Titan the IAU recognizes 81 lakes (lacūs, "small dark plains with discrete, sharp boundaries") of 5km to 240km diameter (median 36km), and three larger seas (maria, "large expanses of dark materials thought to be hydrocarbons"): Kraken Mare, ...

The plan was to switch the lamp on 4 minutes before landing and leave it on. Descent Imager/Spectral Radiometer lamp turned on Close to the surface, Huygens's camera instrument will turn on a light. The light is particularly important for the 'Spectral Radiometer' part of the instrument to determine the composition of Titan's surface accurately. There ...

The Cassini-Huygens mission was a fantastically successful flagship-class mission to the Saturn system, with the Cassini spacecraft spending 13 years in orbit there and delivering the Huygens probe that made the first successful hard-surface landing in the outer solar system. The results are so voluminous, and cover so many different aspects of the Saturn ...

For a start read the Wikipedia article. The next step would be the more than 100 references at the bottom. Many links to NASA, JPL and ESA documents.
