Space shuttle 'Discovery' is at the International Space Station. The shuttle docked with the orbiting outpost early Wednesday. An antenna failure knocked out radar tracking aboard Discovery. So the astronauts had to rely on other navigation tools for the 215-mile-high (346-kilometer-high) rendezvous. As soon as the hatches open, the shuttle crew will use the station's equipment to send down detailed laser images of Discovery's wings and nose. The images were collected Tuesday, but the antenna breakdown prevented their immediate relay to Mission Control. NASA needs to scrutinize the data to make sure Discovery didn't suffer launch damage that could jeopardize re-entry in 11 days. The orbiting crew includes nine men and a record-setting four women.
