I wasn't aware of a space probe to orbit Venus. Given Jupiter's ever-changing weather, and the missed opportunity with Levy-Shoemaker, a deliberate attempt to put a long-lived satellite into a permanent orbit around Jupiter would be a good idea. To keep it busy doing something else useful in addition to taking the same observations of Jupiter over and over, it could also be designed to gather stellar parallax data - something like Hipparcos or its successor Gaia, but also with some conventional imaging capability to help resolve any anomalies like that involving the Pleiades with Hipparcos.

How long- lived it will be is anyone's guess, but NASA's probes have a very good record of lasting far beyond their designed lifespan. If they survive the launch and planetary arrival, that is. ![]() |
