In this July 20, 1969, file photo, Astronaut Edwin E. “Buzz” Aldrin Jr. poses by a U.S. flag on the moon during the Apollo 11 mission.

Washington ? NASA could put a man on the moon but didn’t have the sense to keep the original video of the live TV transmission.

In an embarrassing acknowledgment, the space agency said Thursday that it must have erased the Apollo 11 moon footage years ago so that it could reuse the videotape.

But now Hollywood is coming to the rescue.

The studio wizards who restored “Casablanca” are digitally sharpening and cleaning up the ghostly, grainy footage of the moon landing, making it even better than what TV viewers saw on July 20, 1969. They are doing it by working from four copies that NASA scrounged from around the world.

“There’s nothing being created; there’s nothing being manufactured,” said NASA senior engineer Dick Nafzger, who is in charge of the project. “You can now see the detail that’s coming out.”

The first batch of restored footage was released just in time for the 40th anniversary of the “one giant leap for mankind,” and some of the details seem new because of their sharpness. Originally, astronaut Neil Armstrong’s face visor was too fuzzy to be seen clearly. The upgraded video of Earth’s first moonwalker shows the visor and a reflection in it.

The $230,000 refurbishing effort is only three weeks into a monthslong project, and only 40 percent of the work has been done. But it does show improvements in four snippets: Armstrong walking down the ladder; Buzz Aldrin following him; the two astronauts reading a plaque they left on the moon; and the planting of the flag on the lunar surface.

Nafzger said a huge search that began three years ago for the old moon tapes led to the “inescapable conclusion” that 45 tapes of Apollo 11 video were erased and reused. His report on that will come out in a few weeks.

The original videos beamed to Earth were stored on giant reels of tape that each contained 15 minutes of video, along with other data from the moon. In the 1970s and ’80s, NASA had a shortage of the tapes, so it erased about 200,000 of them and reused them.

How did NASA end up looking like a bumbling husband taping over his wedding video with the Super Bowl?

Outside historians were aghast.

“It’s surprising to me that NASA didn’t have the common sense to save perhaps the most important historical footage of the 20th century,” said Rice University historian and author Douglas Brinkley.

The remastered copies may look good, but “when dealing with historical film footage, you always want the original to study,” Brinkley said.
