ATV: Jules Vernes ready to launch in second half of February
http://news.bbc.co.uk/2/hi/science/nature/7181390.stm
Europe's ATV space truck has been cleared for fuelling, to make it ready for launch towards the end of February. They can't confirm actual dates until NASA confirms the shuttle's launch and landing dates. Is the feeling that ATV is now really ready to go, or are there expectations of more glitches found at the last minute that will delay it another year ? |

It's the first flight of an all new spacecraft, so glitches would not be unexpected. That said, I think that ESA has done their homework on this project. Buying Russian rendezvous and docking hardware made things a bit easier too. I'm hoping for the best for this mission. ATV will do a lot for ISS resupply. Jeff -- A clever person solves a problem.

Buying Russian, does this mean all that clever stuff they had to install is
not redundant? Brian -- Brian Gaff - Note:- In order to reduce spam, any email without 'Brian Gaff' in the display name may be lost. Blind user, so no pictures please!

If the crew have to manually/remotely dock the ATV, it would make sense that the ATV be equipped with compatible software so the crew can use the same software on the station that they use should they need to manually control a progress' docking. And since this is the first flight, it would make sense to provide as much redundancy as possible so that they can compare the commands sent by ATV with those Kurs would be sending. |

Actually, latest I got is a launch at the 22nd of february, at the earliest, with a docking on the 15th of march. Which brings into conflict with the planned docking for STS-123, AFAIK. |

The electronics ( and electrical part ) of the docking system are a completely new system, even if devellopped by RSCE. For the Rendezvous, the ATV system is totally new and developped in Europe. The KURS is aboard the first ATV only, as a payload, to validate the european system but has no role in the actualy guiding of the TAV during its final approch. |

"Brian Gaff" a écrit dans le message de news: .. . Buying Russian, does this mean all that clever stuff they had to install is not redundant? For the docking system, the electronics are brand new and develloped by the Russians to European specifications, so everything is redundant, at least once. For the mechanical part, there is only one electrical motor which isn't redundant, but all it's driving and command electronics are, all the other parts are also redunded at least once. |

If the crew have to manually/remotely dock the ATV, it would make sense There is no way to manually dock the ATV, as one can a Progress. that the ATV be equipped with compatible software so the crew can use the same software on the station that they use should they need to manually control a progress' docking. The command the crew has to send in case of contingency docking are not the same for ATV as for Progress. And since this is the first flight, it would make sense to provide as much redundancy as possible so that they can compare the commands sent by ATV with those Kurs would be sending. This is only done on Ground, comparing the data given by the ATV actual RDV systems with the one of the KURS |

"Brian Gaff" a écrit dans le message de news: .. . Well, looks like its going to be a busy February then, on the station if all goes according to plan. Anyone heard from Nasa if the faulty connector was still faulty when it was tested outside the tank? So with the progress very early feb, the Shuttle sort of a bit later, and the ATV toward the end its going to be a little busy. Gridlock in space? Possibly, but at mid march, not february. ATV spends a lot of time between launch and docking, for demonstration of capability. |
