One unique capability of the aerostat is providing persistent long-range coastal surveillance for up to 128 nautical miles (237 kilometers) at 4,000 feet (1,200 meters) elevation based on actual flight done by the aerostat students. It has the capability to be launched continuously for a week by ensuring the sufficiency of the helium content.
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 ...
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.
Helium is separated out as a byproduct from natural gas, from the Hugoton field, the Panhandle field in Texas, the Greenwood field in Kansas, and the Keyes field in Oklahoma. [6] Much of the recovered helium is piped to the National Helium Reserve in Amarillo, Texas , where it is stored underground in geologic formations for future use.

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 ...
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.
The magnitude and extent of the Arctic air will build into the first full week of January and linger through the middle of the month and will, at times, affect more than 250 million people living ...
