CAPE CANAVERAL, Fla. (AP) - Two astronauts are taking a
spacewalk at the International Space Station.
Stephen Bowen and Alvin Drew floated outside Monday morning.
Bowen, a spacewalking veteran, is a last-minute addition to the
visiting crew of shuttle Discovery.
He's filling in for an astronaut who hurt himself in a bicycle crash last month.
Drew, meanwhile, is now the world's 200th spacewalker.
He's making his first spacewalk.
The two astronauts will install an extension cable and move a
broken ammonia pump to a better storage location.
And in a lighthearted experiment, they'll open a small metal canister and
expose the interior to the vacuum of space.
The bottle will be displayed in Japan.
This is the last flight for Discovery.
