US astronaut Leland Melvin has shared his first encounter with what he thinks might have been an alien on Twitter. Melvin, after being asked by the UFO Sightings Daily, said he once saw a "translucent, curved, organic looking" alien floating out of the payload bay of a space shuttle when it was above Earth.

He contacted his superiors on the ground, but they suggested it was merely ice that broke off of one of the Freon hoses, but the astronaut was quite skeptical about NASA's explanation, although he thinks that was not an intentional lie.
I have not seen one in space or on the ground but thought I saw something organic/alien like floating out of the payload bay. @AstroKomrade and I called the ground to ask what it could be and it was ice that had broken off of the Freon hoses.Translucent, curved, organic looking👽

He also said that when he saw the "alien", the first thing that popped into his head to say was "Houston we have a problem," but stopped himself, since "everyone spins-up" at the phrase.
