I thought this might happen. The Rosetta Mission has been scrapped due to the current doubts about Ariane 5.

I hope they can get both the mission and Ariane back on track pretty soon.

Was talking with ESA friends last week, they were still expecting it to go, because of the lack of backup options. Apparently there is a backup available, but the comet is so old and inactive that it is considered a poor substitute.


Edit to fix spelling.

But they just aired a spread on BBC News!

I reckon it's just a conspiracy to humiliate the BBC. They do a spread on a mission that gets cancelled immediately after. Greg Dyke has enemies.

Rosetta a "1700-kilo bomb" (http://www.go-ariane.com/210/db.cgi?db=Articles&do=search_results&details=1&RecordID=420&RecordID-opt==)

They can't remove the fuel without damaging the tanks.

The home page says the site is "temporarily offline due to maintenance."

Looks like the ariane site is down for maintenance.

Found this article about the teams that filled 'er up in the first place.

Do you think they have a no smoking policy... :D

There's a Google cache of NASA's posting the blurb. It's better than nothing.

10 April 2003: The Rosetta "bomb" cannot be defuelled, Go-ariane

"Apparently the chemical reactions have altered the fuel tank linings. So long as the hydrazine stays inside, everything is okay and Rosetta can wait. But if it is drained the reservoirs internal surfaces would be damaged and Rosetta can not be reloaded. The only solution would be to replace the tanks but these are placed at the heart of the spacecraft. In the words of an Astrium engineer, Rosetta is still "essentially a 1700 kg bomb."
