- Luna 16, launched September 12, 1970, achieved the primary absolutely robotic lunar pattern return mission.
- The mission efficiently landed in Mare Fecunditatis on September 20, 1970.
- Using a robotic arm, Luna 16 collected roughly 101 grams of lunar regolith from a depth of roughly 35 centimeters.
- The pattern container was returned to Earth inside a re-entry capsule on September 24, 1970, touchdown within the USSR.
On Sept. 24, 1970, Luna 16 blazed a brand new path in lunar pattern assortment – one traversed by robots. Though the Apollo astronauts had collected lunar samples on their missions, Luna 16 was the primary occasion of samples being gathered and returned to Earth absolutely robotically, with no astronauts (or cosmonauts) concerned. After blasting off on Sept. 12, 1970, the spacecraft landed in Mare Fecunditatis (the Sea of Fertility) on Sept. 20, and used a 35-inch (90 centimeters) extendable arm to drill into the floor. The drill was in a position to penetrate about 14 inches (35 cm), and just below a quarter-pound (101 grams) of regolith was collected. After 26 hours on the lunar floor, Luna 16 set off for house, its descent stage for the Moon touchdown additionally having been designed as a launchpad for the higher portion of the spacecraft. The hermetically sealed pattern container was saved in a return capsule on the highest of craft. This re-entry capsule safely returned to Earth, touchdown within the USSR on Sept. 24.
