3 He water and number of crew members required life support volatiles produced per year vs. mining rate. This This plot is based on a Mark-III miner model in a 20 ppb 3 He grade region of the Moon.
Dating methods with the least complications in interpretation appear to be sup 3H-sup 3He for postbomb waters and sup 81Kr for waters in the range of 5 times 10sup 4 to 1 times 10sup .
Lithium from Greek romanized lithos lit. stone is a chemical element with the symbol Li and atomic number 3. It is a soft silvery-white alkali metal.Under standard conditions it is the lightest metal and the lightest solid element.Like all alkali metals lithium is highly reactive and flammable and must be stored in mineral oil.
Apr 11 2021 Deuterium-helium 3 fusion rocket Deuterium-Helium 3 Fusion rockets use the fusion reaction D 3 He 4 He p. Start with one Deuteron with a mass of 2.013553 and one atom of Helium 3 with a mass of 3.014932 giving us a starting mass of 5.028485.
In the well-established 3 H 3 He method the apparent age of GW is estimated by comparing the measured concentration of 3 H in GW to the tritiogenic portion of the measured 3 He e.g. Beyerle et .
concentration of the thiosulfate ion S 2 O 3 2- and it remains constant throughout all the experiments. In essence the same amount of I 2 is produced in each experiment at the time the color changes but it takes varying times for this to occur since the t color depends on the reaction conditions concentration of reactants and temperature .

In gas-liquid chromatography the mobile phase is a gas such as helium and the stationary phase is a high boiling point liquid adsorbed onto a solid. How fast a particular compound travels through the machine will depend on how much of its time is spent moving with the gas as opposed to being attached to the liquid in some way.

Helium 3 is a splendid fusion fuel. The atmosphere of Saturn is a great place to harvest He3. Jupiter is closer but harder to get to the He3. No the He3 found on the surface of Luna is so sparse that it is not worth mining. 15 to 50 ppb is pathetically low grade ore.
