Rediscover lunar explorations with a new eye. This is what videos of an enthusiast on YouTube allow, who used artificial intelligence to improve the images.

While the images of the Apollo missions on the Moon remain fascinating in their historical appearance, their quality leaves something to be desired. And for good reason, high-resolution cameras did not yet exist in the 1960s and 1970s. For several years, NASA has been working to restore and improve key videos… but they remain somewhat grainy and fuzzy.

Fortunately, current technologies allow us to change all that. Using artificial intelligence, animage restoration specialist known as DutchSteamMachine  on  YouTube has thus managed to breathe new life into the  memories of these iconic missions, offering a whole new experience for space lovers.

A “spectacular” epic

After the legendary Apollo 11 — where Man first walked on the Moon — and the chaotic Apollo 13,samples from the program’s penultimate mission, Apollo 16,were restored by the expert. Initially shot in 12 frames per second (FPS), the display frequency has been increased to 60 FPS. To achieve this, an AI called DAIN analyzed every second of the original document.

It then generated intermediate images between existing images, to make the video more fluid and compensate for the blur. Finally, the mission’s audio recordings were synchronized with the video. Result? A 4K film of more than 5 minutes, where one can admire the crossing of a lunar rover near the crater Shorty, in the Taurus Valley, while astronomers go to Station 4.

Volunteer work

People use the same AI programs to revive old 1900s film recordings in high definition and color. This technique seemed like a good thing to apply to much more recent images, explains the Youtuber to Universe Today.

DutchSteamMachine makes these improvements in his spare time and posts them for free on YouTube. Its slogan: “Preserving the past for the future”. It plans to continue to enrich these historical documents on its channel. The next time humans set foot on the Moon, however, during the Artemis III mission  in 2024, he will probably no longer need to do such work.
