Moon rocks on Earth come from four sources: those collected by six United States Apollo program crewed lunar landings from 1969 to 1972; those collected by three Soviet uncrewed Luna probes in the 1970s; those collected by the Chinese Lunar Exploration Program's uncrewed probes; and rocks that were ejected naturally from the lunar surface before falling to Earth as lunar meteorites.
In medieval China during the Song dynasty, a meteorite strike event was recorded by Shen Kuo in 1064 AD near Changzhou. He reported "a loud noise that sounded like a thunder was heard in the sky; a giant star, almost like the moon, appeared in the southeast" and later finding the crater and the still-hot meteorite within, nearby.

For example, iron meteorites take much longer to weather and are easier to identify as unusual objects, as compared to other types. This may explain the increased proportion of iron meteorites among finds (6.7%), over that among observed falls (4.4%). [3] There is also detailed statistics on falls such as based on meteorite classification.
Once in a blue moon (literally), the Hunter's Moon will fall on October 31, aka Halloween, and since the lunar cycle is 29.5 days, such an occurrence will always be a blue moon (the second full ...
Luna-25 spent five days journeying to the Moon, then was circling the natural satellite for another five to seven days. The spacecraft then was planned to be set down in the Moon's south polar region, near the crater Boguslawsky. Luna developed an "emergency situation" that occurred during the reduction of the probe to a pre-landing orbit.
The researchers used a Webb instrument called the Near-Infrared Spectrograph to make four observations in 2022 and 2023, getting full coverage of Charon's northern hemisphere.
