China Plans More Moon Missions , After Finding Potential Energy Source.br 'Newsweek' reports that in 2020, br China's Chang'e-5 mission brought br lunar samples back to Earth. .br Scientists have been studying the samples ever since to determine what comprises lunar dust. .br An element known as Helium-3 br was found in the samples.br While scientists have known for decades that the stable, non-radioactive isotope exists on the moon, .br Chinese researchers claim to have determined just how much of Helium-3 br is contained within lunar samples.br They've also deduced extraction parameters. .br Scientists say it is possible that Helium-3 could be used for nuclear fission without producing dangerous waste products.br However, 'Newsweek' reports that a working fusion reactor would have to be engineered before any of this could become a reality.br 'Newsweek' also reports that another diamond-like mineral, Changesite-(Y), br was found in the lunar samples. .br 'Newsweek' also reports that another diamond-like mineral, Changesite-(Y), br was found in the lunar samples.
