Space junk close to International Space Station; new astronauts arrive

Space junk has NASA keeping a close eye on the International Space Station. New residents arrived Thursday.

NASA wants to re-evaluate the orbit of the space station — taking into account any changes as a result of the Soyuz docking — before deciding whether to move the outpost away from three pieces of worrisome space junk.

The International Space Station received three new residents with Thursday's arrival of a Russian capsule, doubling the size of its female crew to an all-time high.

NASA, meanwhile, was keeping close watch on three pieces of space junk that could come uncomfortably close to the orbiting outpost this weekend. They are old Russian and Chinese satellite and rocket parts.

The Soyuz spacecraft — launched two days earlier from Kazakhstan — docked at the orbiting outpost as the vessels zoomed 220 miles (350 kilometers) above the Atlantic near Argentina.

It's NASA's method of getting U.S. astronauts to and from the space station for lengthy missions, and will become the only means of getting people there, period, once the shuttles stop flying late this year or next. Private companies like Space Exploration Technologies, which successfully launched a test rocket into orbit from Cape Canaveral two weeks ago, hope to pick up the slack.

Russian space officials said the docking went exactly as planned and demonstrated the reliability of the Soyuz.

The early evening arrival of the latest Soyuz means there are now two women living full time at the spacestation for the first time ever. No previous space station ever had two female residents at the same time, so the docking marked a historic first.

Shannon Walker, a physicist from Houston, joins Tracy Caldwell Dyson, a California-born chemist on board thespace station since April. Walker took Amelia Earhart's watch into orbit. Four men also are on board now: three Russians and one American. Each will stay for six months and return via a Soyuz.

All six took part in a group hug once the hatches swung open, then accepted a stream of congratulations fromspace agency managers, families and friends gathered in Russia's Mission Control outside Moscow. Nine minutes into the back-and-forth radio conversation, a Russian official urged, "OK, the best half of ISS, would you like to say something? Because only men are talking."

When reminded that Walker had already talked — though briefly — the official said: "Well, if there is nobody else, try to find a third woman if you have one up there."

Wednesday, by coincidence, marked the 47th anniversary of the launch of the first spacewoman, Soviet cosmonaut Valentina Tereshkova.

And Friday is the 27th anniversary of the launch of America's first woman in space, Sally Ride.

Four women were at the space station in April, but only for 1½ weeks. Three of them were brief shuttle visitors.

NASA wants to re-evaluate the orbit of the space station Friday — taking into account any changes as a result of the Soyuz docking — before deciding whether to move the outpost away from three pieces of worrisomespace junk.

Mission managers decided there was no need to dodge a fourth piece of junk, which was expected to pass the station at a safe distance early Friday. That, too, was a chunk of an old Russian satellite.

Arriving with Walker was American Douglas Wheelock and Russian Fyodor Yurchikhin, both of whom visited the space station before. Walker is making her first spaceflight ever; she is married to NASA astronaut Andrew Thomas.

Her mother, Sherry Walker, watched the docking from Russia's Mission Control.

"I can see the big grin on your face," Sherry Walker radioed, "so I know you're having a good time."
