The Wired.com article A Crashed Israeli Lunar Lander Spilled Tardigrades on the Moon says:
Spivack had planned to send DNA samples to the moon in future versions of the lunar library, not on this mission. But a few weeks before Spivack had to deliver the lunar library to the Israelis, however, he decided to include some DNA in the payload anyway. Ha and an engineer on Spivack’s team added a thin layer of epoxy resin between each layer of nickel, a synthetic equivalent of the fossilized tree resin that preserves ancient insects. Into the resin they tucked hair follicles and blood samples from Spivack and 24 others that he says represent a diverse genetic cross-section of human ancestry, in addition to some dehydrated tardigrades and samples from major holy sites, like the Bodhi tree in India. A few thousand extra dehydrated tardigrades were sprinkled onto tape that was attached to the lunar library.
I don't understand the purpose of sending all this human biological detritus to the Moon. There must have been some rationale for why people's hair and blood samples were collected, encapsulated, and sent to the surface of the Moon as a "diverse genetic cross-section of human ancestry". What was it exactly?
I don't find it as inspirational as sending the Voyager golden records and their attempt to capture Earth's populations' vibrancies out of the solar system, or Clyde Tombaugh's ashes past his discovered Pluto, (see photo in Did You Know There are 9 Secret Items Hidden on Pluto’s New Horizons Mission?).
Blood and hair follicles?? Was this some kind of conceptual space art project or is there a clear and possibly scientific purpose for putting bits of 25 human bodies on the Moon?
It sounds more like a potential plot for a future CSI Spaceforce episode.
Or perhaps a DNA degradation experiment helpful as part of Scott Manley's "proposed project" to find out exactly who was the original owner of the Apollo 10 floating turd discussed further in answers to Can someone help Scott Manley explain this Snoopy-capturing maneuver?
