US President Donald Trump has said that his administration will be releasing as much information as possible on UFOs in the near future.
President Trump made the comments as he met with the crew of the Artemis II mission at the White House.
"I think we're going to be releasing as much as we can in the near future," Mr Trump said.
"We're going to be releasing a lot of things… that we haven't," he said.
On 17 April, Mr Trump said his administration's review of UFO-related material uncovered a number of "interesting" documents, adding that an initial tranche of records is expected to be released soon.
In February, he directed US agencies to start releasing government files on UFOs, unidentified aerial phenomena, and possible extraterrestrial life, citing strong public interest in the issue.
The four-member Artemis II crew, NASA astronauts Victor Glover, Reid Wiseman, Christina Koch and Canadian Jeremy Hansen, reached the farthest distance in space any humans have gone before their Orion capsule sailed around the moon's far side.
The Artemis II flight, travelling a total of 1,117,515km in two Earth orbits and a climactic lunar flyby some over 6,400km from its surface, was the debut crewed test flight in a series of Artemis missions that aim to return astronauts to the lunar surface starting in 2028.
There is a "good shot" that a lunar landing will happen while he is still office, Mr Trump said when asked.
"I mean, we don't like to say definitely because then you’ll say 'Oh, we failed, we failed’," he added.
