2004-006A
Rosetta was launched by the first Ariane 5G+ in 2004. Rosetta was built by Astrium (formerly Daimler-Benz Aerospace's Dornier Satellitensysteme) of Freidrichshafen. The spacecraft is box-shaped with 2 solar wings, a propulsion system with 24 10N thrusters and a 2.2m dia HGA. Mass is 809 kg dry with 1720 kg of fuel (1060 kg N2O4 and 660 kg MMH).
2.8 x 2.1 x 2.0m box + 2 panels span 32m. Mass 3065 kg launch with 1670 kg of prop and a 100 kg lander.
Mass at EPC sep is 15708 kg (including full EPS). Mass at EPS burnout is 5892 kg implying a 2827 kg EPS mass at burnout but prior to passivation.
Rosetta will carry the German Surface Science Package (SSP) called Roland.
Rosetta was originally scheduled to carry the Champollion lander, but this was removed from the project in 1996.
Rosetta has Bus Support Module, Payload Support Module.
Control from ESOC.
Rosetta was prepared for launch in 2003 for a rendezvous with 46P/Wirtanen in 2011. After the 2002 Ariane 5 failure, Rosetta was postponed and redirected to 67P/Churyumov-Gerasimenko.
The vehicle was an AR5G+, which is an AR5G with the VEB from the AR5ES (100 kg lighter) and 250 kg extra prop in the EPS stage with an elongated MMH tank. Rosetta used an 123 kg 1194V5 EADS-CASA adapter on the EPS stage and the short A5 payload fairing (12.7m high 5.4m dia). The EPC is the standard AR5G type. The EAP boosters used a P2001 nozzle, 340 kg lighter than standard, pioneered on AR516.

The Rosetta Lander (RoLand) will be deployed onto the comet's surface. The lander was named Philae after the location of an obelisk which helped Champollion decipher the Rosetta stone. Some of the experiments are also carried on the orbiter. Lander is 85 kg, of which 21 kg are experiments.
Size is box + half octagon, 0.9 x 0.9m, with 2.0m span across legs. OWLT is 00:28:20 at 511 million km.
The selected landing site was Site J, subsequently named Agilkia, after the Nile island which now houses the relocated Philae temple complex. After bouncing twice, Philae landed at another site later named Abydos.
