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? |

I was in JPL's Space Flight Operations Facility (SFOF) yesterday afternoon and saw a scrolling display indicating that, at that moment, the DSN was receiving data from Ulysses. So it was still alive as of about 00:00 March 17 UTC...

The day has finally come! The last day for mission operations on Ulysses will be 30th June 2009 (see newsflash item on http://ulysses-ops.jpl.esa.int/). The LAST ground station pass of the mission is currently scheduled for 30th June 2009 over the Madrid DSN 70m station (DSS-63) from around 15:25 to 20:20 UTC (08:25 to 13:20 PDT). This will be a full year after the originally announced mission end date of 1-Jul-2008!
An open-loop slew manoeuvre will be executed before the start of the pass to set up the spacecraft to point directly at the Earth for the middle of the pass in order to maximise the downlink margin. Due to the short notice and low priority for DSN allocation, a full decommissioning of the spacecraft (including some end-of-mission engineering tests that a number of former and present Ulyssess engineers have been waiting to try out) will not be carried out. It is expected that the events in the Ulysses mission support area at JPL leading up to the ceremonial last command to the spacecraft will be carried live on real-time streaming video and/or with mission ops blog update in real-time. Check http://ulysses-ops.jpl.esa.int/ often for announcements and the timeline for the final day of operations. The mission ops team members can now all be counted on the fingers of one hand, so plans can change ... ... so long and thanks for all the fish ... |

The little spacecraft that could... and DID from Oct. 6, 1990 to June 20, 2009. STS-41 got you started, but the rest was on your own!
Fare the well, good friend. -Rob
