- Eight astronauts from various Apollo missions gathered together to celebrate the 50th anniversary of the first manned moon landing, which took place July 20, 1969.
- The group included Buzz Aldrin and Michael Collins from Apollo 11, Walter Cunningham from Apollo 7, and Rusty Schweickart from Apollo 9.
- Some of the astronauts shared hair-raising stories from their space missions during a panel discussion.
- Buzz Aldrin's flamboyant suit and socks garnered lots of attention at the event.
Only four men alive today have walked on the moon. Last month, three of them got together in the same room.
NASA's Apollo program ran 17 missions, which are best known for putting the first people on the moon in 1969. Humanity hasn't set foot on the moon since NASA's Apollo 17 mission in December 1972.
Last month, ahead of the 50th anniversary of the first moon landing - which happened on July 20, 1969 - eight of the 17 surviving Apollo astronauts gathered together for an early celebration at The Explorers Club in New York City.
The group was: Walter Cunningham (Apollo 7), Rusty Schweickart (Apollo 9), Buzz Aldrin and Michael Collins (Apollo 11), Fred Haise (Apollo 13), Al Worden (Apollo 15), Charlie Duke (Apollo 16), and Harrison Schmitt (Apollo 17).

Buzz Aldrin's patriotic socks stole the spotlight on stage.
Buzz Aldrin, the second man to step foot on the moon (after Neil Armstrong), stole the show. Or rather, his outfit did.
Clad in a suit patterned with rocket ships, American flag socks, four gold rings, and two watches, the 89-year-old astronaut certainly stood out.
"His suit was drawing almost as much attention as the man himself," Kunze told Business Insider.
Aldrin has a history of sporting colorful outfits. He even walked in a New York Men's fashion show with Bill Nye in 2017 wearing silver sneakers, a metallic jacket to match, and a shirt that said "Get your ass to Mars."
He continues to advocate for sending future missions to the moon and Mars.
"I can't think of a more appropriate time than five decades from the time that the first Eagle [lunar module] landed on the moon to discuss that the US might lead internationals... to put another eagle on the moon," Aldrin previously told Business Insider.
Aldrin and Collins almost didn't get home
Six of the astronauts - Duke, Worden, Cunningham, Schweickart, Aldrin, and Collins - spoke on a panel hosted by The Explorers Club, as Space.com reported, and recounted some of their hair-raising experiences during the Apollo missions.
Aldrin and Collins reportedly described how Aldrin and Armstrong almost didn't make it back off the moon's surface. (Collins stayed in the command module in lunar orbit in order to reconnect with the other two astronauts on their return.)
San Diego Air and Space Museum Archive Aldrin and Collins' colleague, Apollo 11 astronaut Neil Armstrong, died in 2012.
Apollo 11's lunar module, "Eagle," ferried the astronauts to the moon's surface and back. But while on the moon, Aldrin discovered that a piece of the module was broken.
"I laid down on the floor with my head to the right, which is the co-pilot's side, and I'm looking around at the dust that came in, and there's this little black object. Didn't look like it belonged there. Looked a little closer … this was a circuit breaker that was broken," Aldrin said, according to Space.com.
That circuit breaker was a critical piece of machinery that would help the lunar module get back to Collins in orbit.
"You get ready to land, you push that thing in … you get on the surface of the moon, you pull that out. If you wanna come home, you gotta push that thing in again, but it's broken off," Aldrin said.
"If they couldn't get off, they were dead men, and I was getting home by myself," Collins added, according to Space.com.
Luckily, the astronauts were able to jerry-rig a solution to the problem. Aldrin used a pen to push the button in, and the two were able to leave the moon.
Recently, the US has renewed a push to return men to the moon. On March 26, Vice President Mike Pence announced plans to send astronauts back to the lunar surface by 2024, according to the Associated Press. NASA Administrator Jim Bridenstine has also said that getting boots on the moon is ultimately a step toward the goal of getting astronauts to Mars by the year 2033.
