A white, Teflon-coated jacket worn by Buzz Aldrin during the Apollo 11 mission to the moon in 1969 sold for over two million dollars at an auction on Tuesday.

After flying for the Air Force, Mr. Aldrin joined NASA and became the second man in history to walk on the moon. He was the first to execute a successful spacewalk in the world. Millions of people watched on television as he became the second man to walk on the moon about 20 minutes after Neil Armstrong.

The most valuable American space-flown ever sold at auction was the custom-fitting jacket Mr. Aldrin wore on that mission. The garments worn by the two other Apollo 11 astronauts are owned by the National Museum of African American History and Culture.

The items of Mr. Aldrin were sold at an auction in New York on Tuesday for a combined $8 million.

The Buzz Aldrin sale was the most valuable space exploration sale ever staged. The total collection of the two astronauts still holds the overall record despite the fact that one of them died.

The most sought after artifacts traveled to the moon more than 50 years ago. A summary flight plan of the Apollo mission was sold.

The tiny broken circuit switch that nearly marooned the Apollo 11 crew on the moon and the damaged aluminum pen that Mr. Aldrin used to achieve liftoff were not sold. The auction had an estimate of $1 million, but the bidding slowed to $600,000.

The time felt right to share these items with the world, which for many are symbols of a historical moment, but for me have always remained personal souvenirs of a life dedicated to science and exploration.

The gold-colored lifetime passes to Major League baseball games were sold for $7,560 and the MTV Video Music Awards statuette was sold for $88,200.

The highest honor for civilians, the Presidential medal of freedom, was sold for $277,200. The medals don't appear often at auctions.

There was a letter written by Mr. Armstrong in December of 1973. He tried to convince Mr. Aldrin not to turn his memoir into a movie.

He was unpersuaded. Three years later, the film aired.

Buzz Lightyear is an animated character from the Pixar films and was inspired by Mr. Aldrin.

The 10 lots that came with an NFT were all part of the sale. The phrase "Flown to the Moon" was written on the flight plans with a list of items to bring to space.

It was a touch and go situation before that. There wasn't a lot of clarity. There was always a fear that NASA might shut down an auction.

NASA lost a significant amount of its property as a result of its inconsistent record-keeping, according to the inspector general.

Lawyers for NASA objected to the sale of dead roaches that had eaten moon dust. The insect trio had reached $40,000 before the sale was stopped.

Ms. Hatton said that the price range made the items more accessible than other valuables. The small, white bag that Mr.Armstrong used to collect lunar rock samples was sold by the auction house.

The last mission to the moon, which took place in 1972, was important to the history of humankind.

She said that it was a moment that reminded them of what they could do. It is possible for us to escape our fate of being stuck on this planet. We have the ability to do great things.
