Space shuttle Discovery successfully docked at the International Space Station today after its astronauts overcame a rare antenna breakdown that knocked out radar tracking.

SPACEWALKING astronauts unhooked a 35,000-pound girder from the international space station yesterday, starting the process of moving the solar power tower to another part of the orbiting outpost.

It was moving-in day today for the crew of Discovery, which planned to unload thousands of kilos of supplies and cargo from the US space shuttle to the international space station.

Discovery’s crew used highly sensitive cameras attached to a 15-metre boom today to carefully examine the space shuttle for any signs of damage from the previous day’s launch.
