A vintage vacuum tube showing its internal structure. The large glass envelope maintains a vacuum to allow electron flow and prevents the intense heat of the internal filament from shattering the casing. It is an ideal early specimen.

Peek inside👀 The Electric Arc Shock Tube Facility at Ames is a one-of-a-kind facility that has two shock tubes that can generate some of the fastest shock waves in the world. It simulates extremely hot, high-energy gas environments similar to what spacecraft experience during atmospheric re-entry on Earth and entry into other planetary atmospheres. These tests give scientists insights into spacecraft heating data, helping advance thermal protection system designs for future deep space exploration.

Installing the redesigned fuel transfer tube into the first next generation Super Heavy booster. Roughly the same size as the first stage of a Falcon 9 rocket, the new transfer tube is responsible for channeling cryogenic fuel from Super Heavy's main tank to its 33 Raptor engines and will enable faster, more reliable flip maneuvers and the ability for simultaneous engine startup
