Wallops Arc-Second Pointer (WASP)
The Wallops Arc Second Pointer (WASP) is a balloon-borne attitude control system capable of pointing a telescope or instrument with accuracy and stability down to the arc second, or 1/3600 of a degree of angular measurement. When a high-powered telescope is integrated with WASP, it provides a highly precise...

Overspeed Protection for Turbine Flowmeters in Cryogenic Applications
Flowmeters for cryogenic applications often fail in service. Turbine flowmeters in particular fail due to very high speeds encountered during chill-down operations. Very cold, very high-velocity gas causes the turbine to spin uncontrollably, which quickly degrades bearings. Those...

Thermal Micro-Extraction Laboratory
Typical extractions in the laboratory require a significant amount of sample material, large-scale equipment, and hands-on participation of a scientist. Such a setup is impractical (or impossible), heavy, and expensive to be carried out on spaceflight instrumentation. While great strides are being made to improve...
