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...

Recently, NIRISS, one of NASA’s James Webb Space Telescope’s four primary scientific instruments concluded its postlaunch preparations and was declared ready for science. Now a second of Webb’s four primary scientific instruments, known as the Mid-Infrared Instrument (MIRI), has also concluded its postlaunch preparations and is now ready for science. MIRI’s coronagraphic imaging...

Theoretical physics is full of weird and wonderful concepts: wormholes, quantum foam and multiverses, just to name a few. The problem is that while such things easily emerge from theorists’ equations, they are practically impossible to create and test in a laboratory setting. But for one such “untestable” theory, an...
