In early January 2022, a prototype mag- lev train was rolled out in southwest China’s city of Chengdu, one of the latest developments in magnetic levitation trains. The domestically developed locomotive uses high temperature superconducting and will travel with a designed speed of 620 km/h, according to Southwest Jiaotong University,...

Large spheres have been used to store liquid hydrogen for decades. In fact, two 3,218 cubic meter (850,000 gallon) liquid hydrogen storage spheres have supported space flight pro- grams at the Kennedy Space Center since the mid-1960s. Currently, NASA plans to use the latest and largest liquid hydro- gen tank ever...

Eta Space, a new space company dedicated to developing advanced cryogenic systems for the modern space and energy age, is celebrating its three-year anniversary in June with milestones scheduled for several key projects. Eta Space is developing LOXSAT, a 135 kg demonstration satellite designed to test critical cryogenic fluid management (CFM) technologies...

Vacuum technologies have advanced the field of cryogenics, allowing researchers to push the frontiers of what we know and businesses to apply that knowledge and drive innovation across a wide range of industries. The intersection of vacuum and cryogenic sciences is a demanding one. Pressure and temperature requirements create a...

NASA’s Spitzer Space Telescope, launched in August 2003 and decommissioned in January 2020 after more than 16 glorious years of exploration of the universe at infrared wavelengths, was a technical and scientific marvel. Infrared astronomical studies at wavelengths longward of 1 micron, somewhat beyond the limit of human vision at...
