There was this time at Space Camp… Yes, it can be played; here’s a short Toot Video. Thanks Ball Aerospace!
The Ballers are going back to the design paperwork to try to figure out why the tube lengths inside the dual vessel tank are coiled the way they are (for length matching or heat transfer or ?)
Ball built the Power Reactant Storage Assembly tanks for the Space Shuttle program: “Power Reactant Storage Assemblies (PRSA) are sets of oxygen and hydrogen tanks that provided reactants for the Space Shuttle orbiter and electrical power generation and life support to the shuttle crew. PRSA tanks stored cryogenic oxygen and hydrogen in a super critical state. When the oxygen and hydrogen combine and react chemically in the power generation system (fuel cells), they produce electricity for the orbiter and drinking water for the crew. Oxygen is also mixed with nitrogen for crew cabin pressurization and atmosphere. Each set of tanks consists of vacuum-jacketed storage vessels; supply, vent, and fill lines; electrical subsystems for instrumentation, internal heaters and fluid quantity gauging” — Ball
From my own research, I think it might be from the earliest Apollo LM oxygen tank work; see comment below.
