Aldrin, 94, the last surviving member of the Apollo 11 crew, headlines a gala at the San Diego Air and Space Museum on Saturday night. He'll be joined by astronaut Charlie Duke, who was the voice inside Mission Control for the July 20, 1969 moon landing.
Museum President Jim Kidrick couldn't resist throwing a bash "55 years to the day of one of the most historic moments in not only the history of America, but in the history of the world."
Can't make it to San Diego, Cape Canaveral, or Houston? There are plenty of other ways to celebrate the moon landing, including the new film "Fly Me to the Moon," a light-hearted lookback starring Scarlett Johansson.
You can also explore all things Apollo 11 on a special website by the Smithsonian Institution's National Air and Space Museum.
If nothing else, soak in the full moon Saturday night into Sunday morning.
Here's a rundown of some Apollo 11 tributes:
'The Eagle has landed'
NASA's Kennedy Space Center is holding a moon fest at its tourist stop, just a few miles from where the Saturn V rocket thundered away with Armstrong, Aldrin and Michael Collins on July 16, 1969. Houston's Johnson Space Center, home to Mission Control, is also getting into the act. Four days after they left Earth, Armstrong and Aldrin, in their lunar module, Eagle, settled onto the Sea of Tranquility at 4:17 p.m. Eastern with barely any fuel remaining. "Houston, Tranquility Base here. The Eagle has landed," Armstrong radioed from 240,000 miles away. "No moment united the country quite like when the Eagle landed, as all of planet Earth watched from below," NASA Administrator Bill Nelson said Friday in an anniversary message.
'One small step'
"That's one small step for man, one giant leap for mankind," Armstrong proclaimed as he became the first person to step on the moon. Armstrong grew up in northwestern Ohio's Wapakoneta, now home to the Armstrong Air and Space Museum. The museum's tribute Saturday begins with a pair of "Run to the Moon" races. followed by model rocket launches and wind tunnel demos. John Glenn, the first American to orbit Earth, hailed from New Concord on the opposite side of the state, some 150 miles away. The John and Annie Glenn Museum will be open there on Saturday for your astronaut fix.
'Magnificent desolation'
Aldrin followed Armstrong outside on the moon, uttering "Magnificent desolation." They spent just over two hours treading the dusty surface, before returning to their lunar module and blasting off to link back up with Collins, the command module pilot who had remained in lunar orbit. Armstrong's spacesuit for the moonshot was restored in time for the 50th anniversary in 2019. It's on display at the Smithsonian's National Air and Space Museum in Washington, along with their return capsule. Aldrin and Collins' spacesuits from Apollo 11 are also part of the Smithsonian collection and are currently in storage. Collins died in 2021, less than a year after the 50th anniversary; Armstrong died in 2012.
Splashdown!
The capsule holding Armstrong, Aldrin, and Collins - dubbed Columbia - splashed down in the Pacific on July 24, 1969. They were recovered by the USS Hornet, a Navy aircraft carrier that repeated the job for Apollo 12 four months later. The Hornet is now part of a museum in Alameda, California, with a splashdown party planned aboard the ship on Saturday. Some of the original recovery crew will be there. The Apollo 11 astronauts immediately went into quarantine aboard the Hornet and, along with 48 pounds of moon rocks and soil, remained off-limits for weeks as they were moved to Houston. Scientists feared the astronauts might have brought back moon germs. Most of the rocks remain locked up inside a restricted lab at Houston's Johnson Space Center. The Apollo program landed 12 astronauts on the moon from 1969 through 1972.
Next up: Apollo's twin
NASA aims to send four astronauts around the moon next year - part of a new moon program named Artemis after Apollo's twin sister in Greek mythology. The SLS rocket for that flyaround - short for Space Launch System - is due at Kennedy Space Center next week. It's arriving by barge from NASA's Michoud Assembly Facility in New Orleans. This core stage will get a pair of strap-on boosters at Kennedy before blasting off in September 2025 - at the earliest - with three U.S. astronauts and one Canadian. None of them will land on the moon; that will come on a following mission with another crew no earlier than 2026.
