Tritium (from Ancient Greek τρίτος (trítos) 'third') or hydrogen-3 (symbol T or 3 H) is a rare and radioactive isotope of hydrogen with a half-life of ~12.3 years. The tritium nucleus (t, sometimes called a triton) contains one proton and two neutrons, whereas the nucleus of the common isotope hydrogen-1 (protium) contains one proton and no neutrons, and that of non-radioactive hydrogen ...
By one estimate, the solar wind has deposited more than 1 million tons of helium-3 (3 He) on the Moon's surface. [61] Materials on the Moon's surface contain helium-3 at concentrations estimated between 1.4 and 15 parts per billion (ppb) in sunlit areas, [1] [62] [63] and may contain concentrations as much as 50 ppb in permanently shadowed ...
Helium-3 (3 He [1] [2] see also helion) is a light, stable isotope of helium with two protons and one neutron. (In contrast, the most common isotope, helium-4, has two protons and two neutrons.) Helium-3 and protium (ordinary hydrogen) are the only stable nuclides with more protons than neutrons. It was discovered in 1939.

The live telecast of the Chandrayaan-3 Moon landing event will begin at 5.20pm on India Standard Time (11.50am GMT/UTC) on Wednesday, the country’s space agency Isro noted.
On September 25, 2009, NASA declared that data sent from its M 3 confirmed the existence of hydrogen over large areas of the Moon's surface, [37] albeit in low concentrations and in the form of hydroxyl group ( · OH) chemically bound to soil. [8] [45] [46] This supports earlier evidence from spectrometers aboard the Deep Impact and Cassini probes.
The Chandrayaan-3 is aimed at the lunar south pole, a region with water ice, or frozen water, that could be a source of oxygen, fuel and water for future moon missions or a more permanent moon colony.
