在月球物质中挑选稀有气体的第一次努力的亮点是丰富的太阳风稀有气体;可变的20 Ne/22 Ne,但恒定的21 Ne/22 Ne比率在被捕获的氖的分数;宇宙成因的稀有气体类似于陨石中发现的那些,除了在一个岩石中丰富的131氖,而不是在另一个岩石中;在宁静基地,一块4.1 x 109岁的岩石在3500万至6500万年前到达地表,土壤中的颗粒通常在109年或更长的时间内距离地表一米。
Highlights of a first effort in sorting out rare gases in lunar material are solar wind rare gases in abundance; variable 20Ne/22Ne but constant 21Ne/ 22Ne ratios in fractions of the trapped neon; cosmogenic rare gases similar to those found in meteorites, except for copious 131Xe in one rock but not in another; at Tranquillity Base a rock 4.1 x 109 years old which reached the surface 35 to 65 million years ago, amid soil whose particles have typically been within a meter of the surface for 109 years or more.
