40 years after NASA lands on the moon they admit that there's water up there. Moon Mineralogy Mapper, a NASA instrument onboard Chandrayaan-I, an Indian spacecraft, detected wavelengths of reflected light that would indicate a chemical bond between hydrogen and oxygen in materials on the thin layer of upper soil.
To cover their rears, the PTI reports, "Scientists first claimed that water existed on moon about
40 years ago after they analysed rock samples brought to earth
as souvenirs by Apollo astronauts.
"But they had doubts about the findings as the boxes in
which the moon rocks were brought to earth had leaked
contaminating the samples with air from the atmosphere."
