Intensive Preps Underway For ATV Freighter Launch To ISS

January 28, 2011

The fuel and most of the cargo are loaded and ATV has been hoisted to the top of Ariane 5 as teams on four continents prepare for the 15 February launch of Johannes Kepler from Europe’s Spaceport in Kourou, French Guiana.

With launch scheduled in just 18 days, experts from ESA, partner agencies and industry teams are in the busy final stage of making Johannes Kepler ready for space.

Liftoff is set for 15 February at 22:07 GMT (23:07 CET) from Kourou. After eight days of orbital maneuvers that will enable the Automated Transfer Vehicle (ATV) to synchronize its orbit with that of the International Space Station (ISS), the cargo vessel will dock on 23 February. 

Experts at Kourou handle ATV with care

In the past week at Kourou, experts from ESA and Arianespace carefully fitted ATV into a large protective container to transfer it to the giant vertical integration building.

The transfer took place on 20 January using a massive trailer at a maximum speed of just 15 km/hour.

ATV was removed from the container and, on 25 January, was lifted to the top of the Ariane 5 launcher that will carry it into space.

The vessel is now being integrated onto the launcher together with the adapter that serves as the interface with Ariane. In addition, the white insulating foil layer that thermally protects ATV from the enormous temperature changes in orbit is being attached.

“There is an incredible amount of hard work being done in these final weeks by teams from ESA, CNES, Arianespace and our partners. It’s gratifying to see such dedication to making Johannes Kepler ready for flight,” said Nico Dettmann, ESA’s ATV Programme Manager.

Team work and training at ATV-CC

At the ATV Control Centre (ATV-CC) in Toulouse, France, mission controllers from ESA and CNES, the French space agency, have been making final checks of the mission control infrastructure.

On 28 January, the mission control team conducted a simulation of the critical launch and early orbit phase. On 29 January, a test of the ground control system between ATV and the control center will see controllers receiving live signals via cable from ATV mounted on top of Ariane.

On 2 February, ATV-CC will conduct a final rehearsal involving all ISS control centers covering the flight period from rendezvous with the ISS up to docking. A dress rehearsal of the final countdown will be held on 9 February and will include the Arianespace launch control center in Kourou.

“The operations teams from ESA, CNES and our industrial partners have worked very hard to make sure everything is ready, including many long hours of training to be ready in case of any contingencies. We are ready for ATV’s flight and everyone is keen to get to liftoff,” said Alberto Novelli, ESA’s ISS Operations Manager.

The launch of Ariane 5 and the flight of ATV-2 will make use of ESA tracking stations at Santa Maria, Portugal; Maspalomas and Villafranca, Spain; Redu, Belgium; and, Perth, Australia. The network is centrally controlled from ESOC, ESA’s Space Operations Centre in Germany.
