The Saturn V rocket.
More than 40 years after it carried men to the moon, Apollo 11 is back in the news, thanks to Amazon billionaire Jeff Bezos.
When Apollo 11 lifted off on July 16, 1969, it was carried into the sky by a massive Saturn V rocket and powered by five enormous F1 engines.
After just a few minutes, the engines' job was done; they fell away, plunging into the Atlantic.
Amazon CEO Jeff Bezos was five years old at the time but he says to this day that the moonshot inspired him. And now, four decades later, he gets to play a role in it.
Using sonar technology, Bezos says that his team has located the engines, 14,000 feet below the ocean's surface.
He now plans to recover at least one of them, a project he says will be financed with private money.
On a recent post to his blog, Bezos points out that NASA still owns the engines, but that if one can be recovered, he hopes the space agency will donate it to a museum.
NASA wished him luck, saying they "look forward to hearing more."
