Bill Nelson, the former Florida senator and spaceflight veteran, told CNN Business’ Rachel Crane during a wide-ranging interview on Thursday that it’s not clear to anyone — even in the upper echelons of the US space agency — what the high-speed objects observed by Navy pilots are.
Nelson added that he does not believe the UFOs are evidence of extraterrestrials visiting Earth. “I think I would know” if that were the case, Nelson said. But, he acknowledged, it’d be premature to rule that out as a possibility.
“We don’t know if it’s extraterrestrial. We don’t know if it’s an enemy. We don’t know if it’s an optical phenomenon,” Nelson said. “We don’t think [it’s an optical phenomenon] because of the characteristics that those Navy jet pilots described … And so the bottom line is, we want to know.”
NASA press secretary Jackie McGuinness said Nelson did not establish a formal task force to begin investigating UFOs. However, he did direct researchers to move forward with exploring any lines of questioning around the topic as they see fit.
“There’s not really a lot of data and…scientists should be free to follow these leads, and it shouldn’t be stigmatized,” McGuinness said, acknowledging that UFO research can be negatively associated with unfounded conspiracy theories. “This is a really interesting phenomenon and Americans are clearly interested in it [so if] the scientists want to investigate, they should.”
Nelson said NASA is not working directly with the Pentagon on that report, but he said if NASA’s scientists are able to make headway in identifying the objects, “the Pentagon will know.”
During a press briefing on Wednesday, Thomas Zurbuchen, an astrophysicist and NASA’s associate administrator for science, indicated he does not believe the UFOs are evidence of a technologically advanced alien civilization.
“People tend to underestimate nature. Nature is an amazing place where a lot of miracles happen. And once we understand, it’s like, ‘Why didn’t we think of that?'” he said. “In the realm of science we’re all about unidentified issues and objects…So, using the tools of science, we will do whatever we can to move our understanding forward.”
Kathy Lueders, NASA’s associate administrator for human exploration and operations, chimed in to add, jokingly, “If anyone knows how to do spacecraft design like that I would love to talk to you.”
