  • NEW: Space debris no threat to station or shuttle, NASA says

  • The crew is delivering supplies and spare parts
  • The mission is the last of the 30-year space shuttle program

Kennedy Space Center, Florida (CNN) -- The International Space Station and space shuttle Atlantis are not in danger from an orbiting piece of debris after all, NASA said Monday.

The agency had been tracking a piece of the COSMOS 375 satellite, saying it could come close to the station and the shuttle docked there on Tuesday.

But the agency said Monday that Mission Control verified that the debris will pass a safe distance from the station and shuttle.

The scrap is one of more than 500,000 pieces of debris tracked in Earth's orbit, according to NASA.

A space-debris incident nearly two weeks ago prompted the crew of the International Space Station to take shelter inside two Soyuz capsules when the debris came within 1,100 feet of the station.

Atlantis docked with the International Space Station on Sunday for a week-long rendezvous, two days after blasting off on a historic flight marking the final liftoff of the U.S. shuttle program.

The shuttle crew is delivering supplies and spare parts to the space station, and will pick up a broken pump and transport it back to Earth for inspection, NASA said on its website. The shuttle docked at 11:07 a.m. ET Sunday in an "absolutely flawless" operation, according Cain.

Atlantis' docking with the space station was done by executing a "back flip" maneuver that leaves the shuttle's underbelly facing the space station, where crew members can investigate its condition, NASA said.

After checking for leaks, the crew opened the hatches between the two vehicles shortly after 12 p.m. ET Sunday.

"It was really moving to see the final docking of the shuttle to the space station," Cain said, adding that it was the 12th such time Atlantis has done so.

The crews of Atlantis and the space station also will research the potential for a space refueling system.

NASA Administrator Charles Bolden, speaking to CNN's Candy Crowley on Sunday, said the conclusion of the American space shuttle program doesn't mean the United States is ceding the space race to Russia.

"American leadership will persist for the foreseeable future, I can guarantee you that," Bolden said. In addition to taking cargo to orbit next year, NASA is working to partner with commercial interests in developing a crew vehicle, he said.

"We are hopeful in starting to ask for proposals from industry (in the) early part of next year," he said.

A recent call from President Barack Obama re-emphasized aggressive goals for NASA, including exploration beyond lower orbit and into deep space, Bolden said.

"He wants to have humans on or near an asteroid in 2025, and he wants us to be in Martian orbit with the intent of landing in the 2030s. Those are two very well defined destinations that we're really working hard on," Bolden said.

When crew members conclude their mission and exit the space station, it will break an uninterrupted human presence in space that has lasted more than a decade.

The International Space Station's first expedition began in November 2000. The current expedition, the 28th, is manned by Cmdr. Andrey Borisenko, Alexander Samokutyaev and Sergei Volkov of Russia; Satoshi Furukawa of Japan; and NASA's Ronald Garan and Michael Fossum.

The four astronauts aboard the Atlantis are Cmdr. Chris Ferguson, Doug Hurley, Sandra Magnus and Rex Walheim.

President Richard Nixon commissioned the space shuttle program in 1972, three years after the Apollo program put a man on the moon.

The first shuttle, Columbia, blasted off in April 1981. Since then, space shuttle crews have fixed satellites, performed scientific studies, and ferried materials and people to International Space Station Alpha, a football field-sized construction project in orbit.

In 134 missions, the five space shuttles have ferried 355 astronauts half a billion miles in space, turning heroic feats into the routine.

When Atlantis lands, it will leave the United States with no way to lift humans into space for the first time in decades.

NASA will rely on the Russian space agency to ferry U.S. astronauts to orbit.
