NASA The Expedition 16 crew members aboard the International Space Station continued their preparations to receive Europe’s new unpiloted resupply ship, the Jules Verne Automated Transfer Vehicle (ATV).
At 2 a.m. EDT, Thursday, the ATV fired it engines, bringing it out of a parking orbit and putting it into position to make its first demonstration approach to the station. During its first approach, which is scheduled for Saturday, the ATV will fire its engines several times to bring it approximately two miles from the station. Once in position, the ATV will conduct thruster firings and other systems tests before it pulls back into a phasing orbit.The ATV is scheduled to make its final approach and dock to the International Space Station mid-day, Thursday, April 3.
To prepare for the ATV, the crew members completed rendezvous and docking training exercises, simulating the craft’s final approach in case they may be called upon to override the ATV’s automatic docking controls and abort the approach.(ESA) - After several days spent in a parking orbit 2000 km ahead of the ISS, Jules Verne ATV is now ready to join up with the International Space Station. This first docking attempt can be followed live on 3 April 2008 from 15:30 CEST onwards from one of the European participating centres.
One hour and 6 minutes after lift-off of the Ariane-5 ES launcher from Europe’s spaceport in Kourou, French Guiana, on 9 March 2008 at 05:03 CET, Jules Verne ATV was placed in a circular orbit at 51.6° relative to the equator. At that point in time, the Guiana Space Centre transferred mission authority to ESA’s ATV Control Centre located at the CNES site in Toulouse. Jules Verne ATV was then positioned 2000 km from the ISS while awaiting US Space Shuttle Endeavour’s return to Earth on the night of 26 to 27 March.
In the next few days, the CNES and ESA operational teams, supported by the teams of the ATV prime contractor, Astrium, will carry out manoeuvres aimed at positioning the ATV near the ISS and beginning the final approach phase.
The two main manoeuvres (Demoday 1 and Demoday 2), currently scheduled for 29 and 31 March, are intended to demonstrate the ATV’s ability to dock entirely safely with the ISS and, in particular, to perform an escape manoeuvre commanded by the ISS crew when Jules Verne is just 12 metres away from the station.
The docking of Jules Verne ATV is scheduled for 3 April at 16:41 CEST. The final decision on whether to proceed with this manoeuvre will be taken by the ISS Mission Management Team in consultation with the European partners only 24 hours before the operations. For this first attempt, ESA and CNES will be organising live transmission of the event from the ATV Control Centre at CNES in Toulouse to the various European sites.
The ATV Control Centre at CNES in Toulouse will act as focal point for media in France and will be home to experts who will be on hand for interviews and background information.
Journalists wishing to watch these manoeuvres from one of the above-mentioned sites are asked to kindly complete the linked accreditation form and fax or email it to the Establishment of their choice.
