(Los Angeles, CA) - Since the launch of the manned space program more than 50 years ago, cameras aboard NASA spacecraft have captured thousands of images that have been shared publicly to the delight of millions. Many show stars, views of Earth and other expected sights. However, hundreds of these pictures reveal imagery that leave scientists scratching their heads. NASA'S UNEXPLAINED FILES explores these mysteries and the latest evidence for life beyond Earth. Science Channel viewers will get a rare sneak peek at the all-new season of NASA'S UNEXPLAINED FILES on Sunday, Feb. 21 at 10PM while the series returns for season three on Tuesday, Jan 23 at 10PM.

"Science Channel is the home to more space programming than any other network, from awe inspiring tours of the solar system to series like NASA's Unexplained Files, revealing and exploring the many mysteries that space has to offer," said Marc Etkind, General Manager, Science Channel.

NASA'S UNEXPLAINED FILES dives into the mysteries of some of NASA's most curious missions to explore stories of engineering achievement and human endurance. Each episode offers first hand testimony from astronauts, NASA mission footage, plus beautifully rendered CGI to bring to life these voyages that reveal unexplained sightings that have dogged many of NASA's most famous missions.
