“The world has experienced eight years of helium shortage in the last 17. It’s been a pretty unreliable supply chain,” he said, noting war in Ukraine has indefinitely disrupted Russia’s ...
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.
That’s where helium comes in: With a boiling point of minus 452 degrees Fahrenheit, liquid helium is the coldest element on Earth. Pumped inside an MRI magnet, helium lets the current travel ...
This initiative has received support from NASA, the National Science Foundation, and MTU. The images are sometimes authored by people or organizations outside NASA, and therefore APOD images are often copyrighted, unlike many other NASA image galleries. [4] When the APOD website was created, it received a total of 14 page views on its first day.
Several research organisations have released statements on the scarcity and conservation of helium. [6] [4] Among these are the American Physical Society, counting approximately 53,000 members, the Materials Research Society, an international organisation with 16,000 members, and the American Chemical Society, the world's largest scientific society with some 158,000 members.

Helium also has a very low boiling point (-268.9°C or -452°F), allowing it to remain a gas even in super-cold environments, an important feature because many rocket fuels are stored in that ...
Helium is a natural atmospheric gas, but as a land-resource, it is limited. As of 2012 the United States National Helium Reserve accounted for 30 percent of the world's helium, and was expected to run out of helium in 2018. [23] Some geophysicists fear the world's helium could be gone in a generation. [24]
Of the 2014 world helium total production of about 32 million kg (180 million standard cubic meters) helium per year, the largest use (about 32% of the total in 2014) is in cryogenic applications, most of which involves cooling the superconducting magnets in medical MRI scanners and NMR spectrometers.
