SpaceIL, the Israeli-based private space travel nonprofit backed by billionaire Morris Kahn, came up short in their attempt to land the first commercial payload ever delivered on the Moon. Their Beresheet lander crashed last Thursday, April 11, after a technical glitch prompted its engine to power off and then back on, causing it to come in too fast and strike the lunar surface.
While not ultimately successful, the voyage may have still managed to mark a milestone in the history of lunar exploration. The Arch Mission Foundation, which worked with SpaceIL to put a massive amount of information—including the entirety of Wikipedia—on board, announced this week that the digital library may have survived the impact. That would make it the first substantial repository of knowledge to occupy the Moon.
The data, which was dubbed the Lunar Library, holds an impressive wealth of material—the equivalent of roughly 30 million pages in all. In addition to Wikipedia, there are books selected by Project Gutenberg, 60,000 images, language keys, and a curated selection of music. All of this humanity was packed into 25 nickel discs that are each 40 microns thick. The entire library is roughly the size and shape of a DVD.
Arch Mission Foundation believes that the discs could have survived the impact based on what's known about its trajectory and the crash and is working to confirm its existence. Even if it didn't, there's still something to be said for the idea that "archaeological ruins" of human knowledge now exist there.
The Lunar Library wouldn't be the only human relic left behind. Alan Shepard, the fifth man ever to walk on the Moon in 1971, left golf balls after playing a lunar round. In 1969, the crew of Apollo 11 left a 1.5-inch silicon disk containing goodwill messages from prominent figures in 75 countries written microscopically.
SpaceIL intends to pursue a second lunar lander, with a launch date to be announced. While other countries have landed a vehicle on the Moon—the United States, China, and Russia—this would have marked the first time for a private entity.
