In the Space Station Processing Facility, a worker observes data from the Traveled Work Systems Test (TWST) conducted on the Node 2. The TWST executes open work that traveled with the Node 2 from Italy and simulates the on-orbit activation sequence. Node 2 was powered up Aug. 19 for the testing. The second of three Space Station connecting modules, the Node 2 attaches to the end of the U.S. Lab and provides attach locations for several other elements. Node 2 is scheduled to launch on mission STS-120, assembly flight 10A to the International Space Station.
