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? |

Ulysses finds that the solar wind pressure and magnetic field strength is 20% lower than the previous solar cycle, and the lowest since such measurements began.
Implications are that Voyager 1 and 2 could reach the heliopause sooner than predicted, if this trend continues. |

Even though most of the questions at the audio conference had to do with the earth's climate. sigh.... |
