The sign accompanying the bricks. It reads


RL-10 Thrust Chamber Section

This is a section of an RL-10 thrust chamber wall. The chamber is composed of 360 tubes that circulate liquid hydrogen. While combustion gasses hurtle from the thrust chamber at 6,000 degrees F, super-cold LH2 enters the tubes at -420 degrees F. As the liquid hydrogen cools the thrust chamber wall, the heat transforms it into a gas. That gas, called "gaseous hydrogen" (GH2), is routed through the engine to drive the fuel turbopump.
