Did NASA astronauts see UFOs during the 2006 Atlantis mission?

A YouTube video, posted on April 8, shows three orbs-like structures moving around the Space Shuttle Atlantis, as it floats in orbit during the 2006 mission.

The video was filmed on the Shuttle's final mission in space.

The 9-minute-28-second video, posted on YouTube by Robert Ross, begins with the Atlantis cargo bay. For a few minutes, nothing happens but when the camera pans upward after 4 minute, 55 seconds, three orbs appears in the camera, flying in the increasingly familiar triangle formation.

The ground control commentator on NASA's live public feed believes that it's just camera lens reflection of space junk, but the crew members of the space shuttle doesn't seem so convinced.

It's a structure that's definitely not rigid. Doesn't look like anything I've ever seen on the outside of the Shuttle, that's for sure, one of the crew members said.

The crew later describes how the object quickly moved to the nose of the orbiter, moving away at least 100 feet.

However, the video footage is too blurred to land up on some definite conclusion.

Some YouTube users believe that unidentified flying objects mostly look like few pieces of the many thousands of space debris orbiting Earth.

While some people believe that it is space debris, Gather.com believes the objects may not be of UFO-kind, but says it seemed strange NASA would want to kill the prospects of any UFO rumors cropping up.
