Astronomers and engineers are looking to September for a flight demonstration of NASA hardware that could deliver “arc second” precision pointing and stability suitable for planetary observations using instrumentation suspended from high-altitude balloons. Balloons have long afforded adequate stability for low-cost observations of the Earth, Sun and distant stars above atmospheric distortions. The new Wallops Arc Second Pointer (WASP), developed at NASA’s Wallops Flight Facility, will ...
