The moon is strewn with minuscule beads of glass that have formed over billions of years as soil ejected during asteroid impacts cools and falls back to the lunar surface. An analysis of lunar samples delivered to Earth by China's Chang'e-5 probe has now revealed that those beads contain a substantial amount of water.
The presence of water on the moon is no news. NASA's lunar orbiters found evidence of the life-giving liquid inside the moon's permanently shadowed polar craters already in the 1990s. In the 2000s, a reanalysis of samples from the manned Apollo missions of the late 1960s and 1970s detected hydrogen in the lunar soil. And the recently retired infrared telescope SOFIA confirmed in 2020 that water is present on the moon, even outside the dark craters. The origin and behavior of this lunar water is, however, still somewhat unclear.
However, the glass beads found in the 61.1 ounces (1,731 grams) of lunar regolith brought to our planet by Chang’e-5 in December 2020 might provide the missing piece in this puzzle.

Aos anos que eles sabem isso...
ReplyDeleteHehehe...
ReplyDeletelhe garanto q nem tantos, mas sim daqueles que possam vir decobrir algo muito relevantemente positivo para estas ciências, que são - pasmém - muitas vezes até punidos por algum tipo de ditadura ímplicita.
Quando os Americanos foram a primeira vez na Lua, eles trouxerar várias amostras de solo, de diversos pontos da Lua, para análise na Terra.
ReplyDeletePor que agora, eles tiveram de fazer outra experiência, para descobrir a composição do solo lunar?
Será que a primeira vez, eles não foram na Lua?
provavelmente eram rochas terrestres, havia a famosa rocha "c", que estava marcada com a letra "c" no cenário em estúdio onde filmaram as cenas todas da falsa alunagem..
