So, apparently, humans found evidence of water on the Moon all the way back in 1976, but nobody was paying attention. Granted, it wasn’t a LOT of water (0.1% of sample), but still. From Technology Review:
One of the least known missions is the Soviet Luna-24 sample-return mission which landed on the lunar surface in August 1976. This drilled some 2 metres into the lunar surface, extracted 300 grammes of rock and then returned to Earth. An impressive feat by any standards but one that has been largely forgotten in the west.
A Soviet team analysed the sample and found unambiguous signs of water in the rock–they reported that water made up 0.1 per cent of the sample’s mass. In 1978, they published the result in the Russian journal Geokhimiia. This journal also has an in English language version but it was not widely read in the West.
Crott says that today the work has been almost entirely forgotten. “No other author has ever cited the Luna 24 work,” he says.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
