NASA astronaut Chris Cassidy saw a strange object out the window of the International Space Station ISS), and caught it on camera.
"Earlier this morning (Aug. 19), Chris Cassidy had noted an object that was floating past the station near the station's Progress 52 cargo ship," said the NASA TV narrator. "That object has been identified by Russian flight controllers as an antenna cover from the Zvezda service module," a NASA TV anchor said, Discovery News reported.
Sightings of Unidentified Flying Objects (UFOs) around the ISS have been frequent over the past year, the Huffington Post reported.
Last Christmas a video was posted on Youtube showing a NASA camera shot of what seemed to be a silver object moving through space.
That New Year's Day the same Youtube poster uploaded another video of UFOs near the ISS.
"Spacecraft-generated 'dandruff' has been seen since the very first human spaceflights, when the non-intuitive relative motions and impossible-to-judge distances in the [un]earthly environment of outer space tricked observers into misinterpreting visual stimuli," James Oberg , a former space engineer who specialized in NASA space shuttle operations and is currently the NBC News Space Consultant, told the Huffington Post.
"It shouldn't be surprising that only half a century later, most folks watching YouTube videos are still totally flummoxed by what they understandably and excusably can't comprehend," he said.
Oberg doubts the sightings indicate and alien life force flying around in space, but said viewing the cameras could help alert NASA to equipment malfunctions.
