Pneumatics Help SpaceX Pursue "Out-of-This-World" Goals

Despite recent catastrophes, the call for space exploration will continue. California-based SpaceX, a space transport services company, is pursuing development of its Falcon 9 launch vehicle. Engineering360 looks into the current Falcon 9's construction and technology. One item discussed is the stage separation system's use of pneumatics instead of conventional pyrotechnics. The idea: allow reliable, low-shock separation that can be tested on the ground.
