Atmospheric mining is the process of extracting valuable materials or other non-renewable resources from the atmosphere. Due to the abundance of molecular hydrogen and helium in the outer planets of the Solar System , advances in technology may eventually make mining their atmospheres a favorable alternative to mining terrestrial surfaces.
Map showing helium-rich gas fields and helium processing plants in the United States, 2012. From USGS. Helium production in the United States totaled 73 million cubic meters in 2014. The US was the world's largest helium producer, providing 40 percent of world supply. In addition, the US federal government sold 30 million cubic meters from storage.
The Crude Helium Enrichment Unit in the Cliffside Gas Field. Remnants of the Amarillo Helium Plant in 2015. The National Helium Reserve, also known as the Federal Helium Reserve, is a strategic reserve of the United States, which once held over 1 billion cubic meters (about 170,000,000 kg) [a] of helium gas.
By one estimate, over 150 tons of regolith must be processed to obtain 1 gram (0.035 oz) of helium 3. [71] China has begun the Chinese Lunar Exploration Program for exploring the Moon and is investigating the prospect of lunar mining, specifically looking for the isotope helium-3 for use as an energy source on Earth.

Helium and neon are also used as refrigerants due to their low boiling points. Industrial quantities of the noble gases, except for radon, are obtained by separating them from air using the methods of liquefaction of gases and fractional distillation. Helium is also a byproduct of the mining of natural gas.
Helium storage and conservation is a process of maintaining supplies of helium and preventing wasteful loss. Helium is commercially produced as a byproduct of natural gas extraction. Until the mid-1990s, the United States Bureau of Mines operated a large scale helium storage facility to support government requirements for helium.

Liquid helium is a physical state of helium at very low temperatures at standard atmospheric pressures.Liquid helium may show superfluidity.. At standard pressure, the chemical element helium exists in a liquid form only at the extremely low temperature of −269 °C (−452.20 °F; 4.15 K).
