What is up with the tiny Ulysses spacecraft that was launched in 1990 to study the solar whatever at high lattitudes? Last I heard it was in danger of dying because the RTG power was running low and at aphelion there was a risk of the hydrazine freezing/exploding in its propulsion system. Well that was like a year ago and I haven't heard anything since. It looks like it should've passed aphelion by now and should be out of danger.....
Its been going up there for over a full solar cycle, is it one of the missions on the chopping block because of the new humans on moon/mars thing? |

There goes Ulysses...again...
I really enjoy Dr. Marsden' updates: "It's amazing to think that a satellite that was designed in the mid-1970's and built in the early 1980's is still operating perfectly in 2007!" -------------------- "Ride, boldly ride," The shade replied, "If you seek for Eldorado!"

"It's amazing to think that a satellite that was designed in the mid-1970's and built in the early 1980's is still operating perfectly in 2007!" It's not very great achievement, Ulysses at last was launched in 1990. Pioneer 6, the first in a series of solar-orbiting satellites was launched December 16, 1965. Although the spacecraft have not been regularly tracked for science data return in recent years, a successful telemetry contact with Pioneer 6 was made on December 8, 2000 to celebrate 35 years of continuous operation since launch. As of March 15, 2006, Pioneer 6 is still described as "extant", and is the oldest operating space probe (if still operating). -------------------- Free software for planetary science (including Cassini Image Viewer).
