Interesting. The ESA site says, Jules Verne ATV under control after a textbook launch

Quote:

All navigation systems onboard, the star-trackers, the GPS system are working nominally and the solar arrays, which deployed very smoothly, are delivering full power. However the spacecraft on board computers detected a slight difference in pressure between the oxidizer and the fuel that compose the propellant. This caused the ATV to immediately switch over to the second of four propulsion chains, as it is designed to do.

Engineers at the Control Centre in Toulouse and at the prime contractor premises EADS-Astrium in Les Mureaux are evaluating and analysing the data coming from the spacecraft and are assessing the consequences, if any, in the immediate planning.

I wonder which is more recent. No timestamp on either that I see.

I guess we wait for the analysis. Any briefings scheduled?

A little more, SpaceflightNow: Engineers assess problem aboard Jules Verne craft

Quote:

An electronics box on Europe's first cargo ship shut down a propulsion system command chain responsible for a quarter of the space-age delivery truck's maneuvering thrusters, officials said Sunday.

"We really don't think it's anything serious, but we're studying it prudently," said Alan Thirkettle, the European Space Agency's international space station program manager.
[...]
"This is something we're looking at in a lot of detail now," said John Ellwood, ATV project manager. "I think the very good news is that all the failure detection and recovery action all went perfectly. It measured a small anomaly, immediately went onto the other chain, which is working perfectly."

I declare my launch coverage over.

I'm taking any discussion of approach, docking (in, what, about 3 weeks?), use, undocking, and sad, fiery disposal back to the older topic, Jules Verne in space.
