Using a sounding rocket to help calibrate NASA's SDO
Greenbelt MD (SPX) May 22, 2015
Watching the sun is dangerous work for a telescope. Solar instruments in space naturally degrade over time, bombarded by a constant stream of solar particles that can cause a film of material to adhere to the optics. Decades of research and engineering skill have improved protecting such optics, but one crucial solution is to regularly recalibrate the instruments to accommodate such changes. In mid-May, the seventh calibration mission for an instrument on NASA's Solar Dynamics Observatory, or SDO, ... read more
