What are the disadvantages of cassini-huygens?

Answer 1

Any long-duration space probe is going to have some compromises.

Size: we'd like to have sent along some extra fuel, added additional instruments, perhaps another lander - but there's a hard limit to how much weight we can launch into space.

Power: If we use solar power panels, then we lose power as the spacecraft goes away from the Sun, and Cassini is in orbit around Saturn - 9.5 times farther from the Sun as the Earth is. If we use radioisotope power cells, then the probe will lose power as the radioactive elements decay over time.

Huygens: The Huygens lander was a one-shot deal; it only survived for about 90 minutes after landing on Titan, and only one photograph of the surface was transmitted. There was no second chance. Only half of the hoped-for data was received because one of the two communication channels failed.

Additionally, robot space probes are only capable of finding answers to known questions; we can't ask follow-up questions that we hadn't anticipated. The Cassini probe was designed in the early 1990's and launched in 1997; it didn't arrive in the vicinity of Saturn until late 2004. Sometimes stuff breaks during the course of a several-year journey.

Answer 2

Some disadvantages of the Cassini-Huygens mission include the high cost associated with the mission's development, launch, and operation, as well as the limited lifespan of the spacecraft due to its dependency on power from radioisotope thermoelectric generators. Additionally, the spacecraft is now out of contact with Earth since its mission ended in 2017, limiting our ability to gather further data from Saturn and its moons.
