Moon Rocks. and samples from the moon
No woman has ever been to the moon. The only people who have walked on the moon were male astronauts from the United States during the Apollo missions in the late 1960s and early 1970s.
Rock, core, and soil samples, as well as many hundreds of pictures and many hours of video
by the moon.
Various samples of rocks.
Rocks from the moon.
No girls have been to the moon, no women have been there either.
PARTIAL ANSWER:Over 800 pounds of moon rock have been returned to earth but I'm not sure of soil samples which would add considerably to that number.
As yet no living organisms have been found in the samples brought back from the moon. As there is no air on the moon, and all organisms have to breath air, the fertility of the ground is most unlikely, but I may stand corrected on this matter.
Yes collecting moon rocks was their main jobs.
By the moon
The Giant Impact Hypothesis is probably the most favoured today. This has it that a body about as massive as Mars, (Now called Theia) had accumulated in the Lagrange points, and about 4.5 billion years ago, this made a low velocity collision with the early Earth. It is thought that most of the nickel-iron of the Moon descended into the core of the Earth.Computer models concur with this hypothesis, and further support is obtained from samples collected from the Moon itself.
