The handoff has been accomplished. Atlantis' 50-foot robot arm has released its grip on the truss, leaving the $372 million structure in the hand of the station's arm for installation tomorrow. The truss will remain secured on the station arm overnight.

With only an inch or so of clearance, astronauts Dan Burbank and Chris Ferguson, operating the shuttle Atlantis' 50-foot-long robot arm, carefully lifted a 35,000-pound solar array truss from the orbiter's cargo bay today, maneuvered it safely past the ship's heat shield inspection boom and out over the shuttle's left wing.
Canadian astronaut Steve MacLean, operating the space station's more massive Canadarm 2 from inside the Destiny laboratory module, then grappled the massive payload in a high-flying handoff, setting the stage for attachment to the station's unfinished solar array truss Tuesday.
"There you have it, the great Canadian handshake," MacLean called. Both robot arms were built in Canada and both were critical to today's operation.
