On Sunday, astronaut Jan Davis used the arm to raise and maneuver the 4-ton environmental research satellite retrieved by the shuttle crew the previous day. The satellite was used to simulate two of the earliest station components that will be joined by astronauts in orbit. All told, the Discovery crew tackled two dozen major projects following their Aug. 7 liftoff. Those included the successful deployment and retrieval of the environmental research satellite that scanned the Earth's atmosphere for traces of the chemicals responsible for ozone damage. They tested a new Japanese-built robot arm intended for use on the new space station and conducted biotechnology experiments.
Discovery is in great shape.
The crew is in excellent spirits.
