Launch vehicles, particularly the upper stages, often use cryogenic rocket propellants such as liquid oxygen, liquid hydrogen and liquid methane because of their high specific impulse and high storage density. The pressurization, control and distribution of these propellants requires sophisticated valving that can operate and seal at these extreme temperatures....

On December 15, GenH2, a leading developer of liquid hydrogen infrastructure solutions, formally announced the appointment of renowned NASA veteran and company co-founder James E. Fesmire as Chief Architect and Chief Technology Officer. In his role, Fesmire will shape GenH2’s technology vision and drive product evolution and expansion. Known for...

Cost- and energy-efficient rapid cycling magnets for particle accelerators are critical for particle physics research. Their performance determines how frequently a circular particle accelerator can receive a bunch of particles, propel them to higher energy, send them to an experiment or target station, and then repeat all over again. A...

For physicists trying to harness the power of electricity, no tool was more important than the vacuum tube. This lightbulb-like device controlled the flow of electricity and could amplify signals. In the early 20th century, vacuum tubes were used in radios, televisions and long-distance telephone networks. But vacuum tubes had...

A new $15.8 million grant from the National Science Foundation (NSF) will produce a detailed design for the world’s most powerful superconducting magnet at the Florida State University-headquartered National High Magnetic Field Laboratory (CSA CSM). While the National MagLab is already home to more than a dozen world-record magnets used...

On December 25, the largest and most powerful space telescope ever constructed by NASA was successfully launched from Earth. With unprecedented technology, the James Webb Space Telescope (JWST) will peer both near and far, from the planets and bodies in our solar system to the deepest reaches of space, where the...
