Former NASA astronaut Leland Melvin is not only famous for his space work, but also for a. Now he's back in the limelight thanks to a Twitter exchange about strange sights in space.
Melvin asked a question last week from Scott Waring, founder of the popular blog UFO Sightings Daily. Waring asked for Melvin's "Outlook on the existence of intelligent alien life in our solar system" and whether the retired astronaut had ever seen a UFO.
Melvin, who was logged in space for more than 565 hours, replied that he had not seen a UFO in space or on the ground. And then it got interesting when he added, "But I thought I saw something organic / extraterrestrial, as if floating out of the cargo bay."
He wrote that he and NASA astronaut Randy Bresnik had called down to ask what that was. NASA told them it was ice that broke a freon hose. Melvin described it as "translucent, curved, organic-looking," then added an alien head emoji at the end of the tweet.
Waring responded with a "Wow!" and asked if NASA could have lied about what the object really was. Melvin replied, " Hmmm, do not think so, but you never know ."
If we are looking for an explanation for a bizarre sighting in space, ice sounds like a perfectly reasonable one. Melvin's last space mission took place when Space Shuttle Atlantis visited the International Space Station in 2009, and it seems that the Earth has not been haunted by organic / alien-like creatures ever since.
CNET turned to Melvin to find out what mission he was when he saw the object and what he thought.
