Huge vacuum chambers on Earth are crucial for building and testing spacecraft, so we explore further into space. The photo above is Vacuum Chamber 5, where electric propulsion and power systems are ...

[Nick Poole] does a lot of custom work with vacuum tubes — so much so that he builds his own vacuum tubes of various shapes, sizes, and functions right on his own workbench. While the theory of vacuum ...

Stan Grisnik describes how NASA’s huge craft-testing facility can recreate the vacuum conditions of space. Inside the Space Power Facility The cost of failure of a space mission is millions or even ...

Scientists have validated a new approach to measuring extremely low gas pressures called CAVS, for cold atom vacuum standard. The quantum-based technique promises to be useful for applications such as ...
