Quote: Already there is talk of a problem with the propulsion system. Hopefully it
can be resolved.
Now resolved according to:
http://spaceflightnow.com/ariane/v181/080311prop.html
They say that the problem was "an issue within the chain's helium gas
system". I guess because it was fixed (or worked around) so quickly,
it was a transient kind of thing? I don't know, the article doesn't
really say much about what happened. They did say that "commands to
reintegrate an electronics box which drives that part of the
propulsion system were up-linked to the spacecraft" which kind of just
sounds like they re-set things. But I don't know, maybe they uploaded
some kind of patch or parameter or something to fix the issue. I
probably shouldn't read too much into a non-technical description like
this one way or the other. |

Quote: The 181th launch of Arianne 5 spacecraft occured about an hour ago. It
succesfully put into orbit the Jules Verne ATV.
(the 181 number was mentioned by a commentator on the ESA TV live feed).
It was mentioned that the plan was to have an ATV launch every 18 months.
Docking with ISS in early April after the shuttle has left.
ATV is 20 tonnes. Columbus was 12 tonnes.
Europe has now switched from being a theoretical partner of the ISS to
an important one with functional contributions. (Columbus and now ATV)
12-mar : test of its emergency "stop" systems.
29-mar : approaches to 3500 m from ISS.
01-apr : docking to ISS.
That's good news that we can all appreciate, especially since our NASA
is so pathetic that it can't even win the Google X-Prize if it tried.
