Abstract: The Wallops Arc Second Pointer (WASP) is a high-altitude scientific balloon gondola control system developed by the National Aeronautics and Space Administration (NASA), designed for high-precision astronomical observation missions. This system integrates sophisticated mechanical and electronic components, complemented by super-pressure balloon technology, to conduct long-duration flights in the near-space environment while maintaining sub-arcsecond pointing accuracy. The WASP system's flexibility and standardized design enable it to be adapted to a variety of scientific payloads, catering to diverse mission requirements. In the realm of space science, the application of the WASP system has broadened the research horizons of high-altitude scientific balloons and has provided innovative solutions for the establishment of near-space observatories, furthering the exploration of the near-space domain. The successful test flights and applications of the WASP system have established a solid foundation for its utilization in the fields of planetary science, astrophysics, and Earth observation.
