Luna 16: A Robotic Handful from the Moon
Transcript
Luna 16 set out to do something previously achieved only by crewed missions: bring lunar soil back to Earth without astronauts. The Soviet spacecraft was a Ye-8-5 sample-return design, developed and managed by Lavochkin, with a remote arm for collecting material. After entering lunar orbit, it landed in the northeastern Sea of Fertility at 05:18 UT on September 20, 1970. Less than an hour later, at 06:03, its automatic drill penetrated the surface to gather soil. That sequence was the turning point: landing, collecting, and returning a lunar sample through an automated mission. Siddiqi records that Luna 16 successfully returned lunar samples, though the account available here does not specify their mass. He describes it as the first fully automatic recovery of lunar samples from the Moon, and a Soviet deep-space landmark after five consecutive failures. Its importance was practical as well as symbolic: robotic exploration could bring lunar material home.

The grasshopper wart remedy Cowan records
Cowan reports that Swedish peasants had Decticus verrucivorus, a kind of grasshopper, bite warts on their hands. They believed the black fluid it released from its mouth would make the warts disappear. This was a folk remedy he recorded, not a tested or recommended treatment[1]. He also says boys attributed wart-curing power to similar black fluid from grasshoppers, which they called “tobacco spit”[2].
