A NASA astronaut's interview on a Spanish TV show is causing excitement among UFO enthusiasts, with some bloggers claiming that he was evading questions regarding the recent speculation that UFOs were witnessed hovering around the International Space Station during a live camera feed, Epoch Times reported.

Joseph Acaba, who was aboard the ISS from May 17, 2012 until Sept. 17, 2012, appeared to intentionally dodge the question of whether he had seen any UFOs while docked in the ISS, according to multiple bloggers.

During the interview, allegedly recorded in 2012, the astronaut's answer might have been lost either in translation or network disturbance, the Huffington Post notes.

"Have you seen unidentified objects in space?" a person questions in the video.

Acaba laughs and asks: "Objects on earth? I do not quite understand the question but ... we can see the world from here and objects in space like Mars, the moon..."

"It appears that he is asked about the UFOs seen on the live space station cam, but the astronaut seems to be hesitating for a few seconds," states UFO Sightings Daily.  

"Also, you can hear the people back on Earth applaud the person for asking the question. This was a live broadcast on the ISS cam, so they were unable to edit the question out. As seen from the flag on his leg, he is from Puerto Rico, however I don't see him on the list of ISS current crew."

In a viral YouTube video uploaded by NASA two months ago, the space-walking astronauts were seen performing their mission when suddenly around the 1:50-minute mark, a mysterious craft appeared and hovered for a few seconds, prompting a web of speculations.

Earlier reports in 2014 have also indicated sightings of UFO's visiting the habitable space station, Examiner reported.

Meanwhile, a live video feed on Jan. 29 featured the ISS being joined by a yellow-colored elliptical UFO, which eventually docked with the artificial satellite. Although the video raised speculations and various theories, NASA refrained from commenting on the unknown spacecraft.
