Case Study: MISSIONS

Program: Solar EUV Hitchhiker

Agency: USC

The SEH, or Solar Extreme Ultraviolet Hitchhiker, is a series of secondary payloads flown on the space shuttle designed to obtain absolute solar Extreme Ultraviolet (EUV) flux in the 200-1700 angstrom wavelength region utilizing four separate instruments: a neon ionization cell, a helium double ionization cell, a highly stable silicon photodiode, and a spectrometer assembly.

The focus of this mission is to measure, analyze, and interpret the data. The end results help to improve global solar atmospheric models and our understanding of solar variability.

Current Space Systems Research Corporation personnel designed and developed the payloads for the University of Southern California, which included the initial concept development, design trades and analysis, and tracked the design fabrication.
