When Nancy Lee Carlson discovered an online auction two years ago for moon dust, she couldn’t believe her luck. A geology buff, she spent childhood summers scouring for rocks along Michigan’s Lake Superior, but wasn’t a serious collector. She figured the dust was genuine because it was being auctioned on behalf of the U.S. Marshals Service. 
  
 “Ooh boy, that’s something I’d love to have,” she recalls thinking, remembering the astronauts and spacewalks she watched growing up. The 62-year-old hadn’t bid on anything as high as... ||||| Shortly after Neil Armstrong took "one giant leap for mankind" by stepping on the surface of the moon, he did what any tourist does: He collected a souvenir. 
  
 Armstrong, the first person to set foot on the lunar surface, scooped some lunar rocks into a bag, then placed it into another bag, and put it in the pocket of his space suit. 
  
 From there, the outer sample bag, containing traces of moon dust, took a long and torturous path before it was mistakenly put out to public auction and scooped up by a suburban Chicago lawyer for $995. Now, the incredibly rare artifact will go on auction, and auctioneers expect it to fetch $2 million to $4 million. 
  
 Because NASA's lunar objects generally are prohibited from being privately owned, curators at Sotheby's auction house believe the moon dust bag to be the only privately held object of its kind in the world. 
  
 "This is a once-in-a-lifetime event," said Cassandra Hatton, a vice president at Sotheby's in New York. "This transcends space exploration. It's a relic of one of the most historic achievements of humanity." 
  
 Like many baby boomers who watched the lunar landings as kids, the bag's owner, Nancy Lee Carlson, an attorney from Inverness, was fascinated by the Apollo missions. 
  
 She came across the bag, labeled "lunar sample return," on an online federal auction site, where it ended up after a bureaucratic misunderstanding. After no one bid on it in three initial auctions, she bought it in February 2015. 
  
 She initially kept the object in her bedroom closet, then sent it to NASA to verify its authenticity. NASA officials verified that the bag indeed contained moon dust, a dark-gray fine powder, like graphite, that one astronaut described as smelling like gunpowder. 
  
 But once officials knew the bag came from the moon, they confiscated it as government property. Carlson filed a federal lawsuit, and in February, a judge concluded that she had legally acquired the moon bag and was entitled to keep it. 
  
 After the Apollo 11 astronauts returned to earth in 1969, the lunar objects they collected were generally stored in vaults at the Johnson Space Center in Houston, said Paul Spudis, a senior staff scientist for the Lunar and Planetary Institute in Houston, which does work for NASA. 
  
 Some lunar samples were given as gifts to foreign nations and dignitaries, and they've been known to show up on the black market, while others were loaned out for research or public display. 
  
 This bag ended up in the possession of Max Ary, who ran a museum called the Kansas Cosmosphere in Hutchinson, Kan., according to court records. Ary was convicted of stealing and selling space objects, and government officials seized his possessions and sold some of them for restitution. Among the items sold was the lunar sample bag, which was confused with another bag that did not contain moon dust. 
  
 NASA opposed private ownership of the bag, which was part of an epic national program, and issued a statement following the court ruling: "This artifact, we believe, belongs to the American people and should be on display for the public, which is where it was before all of these unfortunate events occurred." 
  
 Carlson has said she initially wanted the bag to take it to local schools for educational purposes, but once its rarity became a national media story, she changed plans. 
  
 Some of the proceeds of the sale will be used to benefit charities, including the Immune Deficiency Foundation and Bay Cliff Health Camp, according to Sotheby's. Carlson also plans to set up a scholarship in speech pathology where she went to school, Northern Michigan University. 
  
 The auction will be July 20, on the 48th anniversary of the landing of Apollo 11, with bids taken in person, by phone and online.

Only one man was able to be the very first to walk on the moon. Now, an auction that's just as singular. On July 20, Sotheby's will auction a bag containing traces of moon dust, which a Chicago-area woman picked up for $995 and which is expected to sell for as much as $4 million. It's an extreme price befitting the extreme story behind the bag, which Neil Armstrong used to store lunar rocks collected from the moon after the Apollo 11 landing. The bag's convoluted history includes the 2003 FBI raid on the home of Max Ary, the former director of a Kansas space museum. The Wall Street Journal reports the director was convicted of theft tied to his auctioning of some NASA artifacts, and his possessions were seized, with some auctioned for restitution—which is when the goof happened. How Ary ended up with the bag is still a bit murky, but what is clear is that the government auctioned it as "one flown zippered lunar sample return bag with lunar dust ('Lunar Bag'), 11.5 inches; tear at center. Flown Mission Unknown," and Nancy Lee Carlson scooped it up. The Sotheby's listing explains Carlson wanted to learn more about her bag's history, so she sent it to NASA; officials there realized what had happened and refused to return it, until a court forced them to earlier this year. "This is a once-in-a-lifetime event," Sotheby's Cassandra Hatton tells the Chicago Tribune, which explains why: This may be "the only privately held object of its kind in the world," at least as far as legally sold lunar objects go. Carlson plans to donate some proceeds to charity and set up a scholarship at her alma mater, Northern Michigan University. (This widow can sue over NASA's brutal sting operation of her.)
