Abstract
Aspera is a NASA Pioneers Mission designed to measure faint OVI emission around nearby galaxies with unprecedented sensitivity. The SmallSat payload consists of two identical co-aligned spectrographs, both operating in the Far Ultraviolet (FUV) between 1030−1040 Å. Missions operating at FUV wavelengths are particularly sensitive to contamination, as short wavelengths are easily scattered and absorbed by contaminants deposited on payload optical surfaces. A strict contamination control plan is critical to avoiding a severe loss in FUV throughput. Aspera contamination control efforts have been tailored to fit within the scope of a sub-Class D mission, a challenge that has become increasingly relevant as advances in FUV optics/detectors drive an uptick in smaller platform, contamination sensitive UV payloads. Contamination monitoring is used to audit the cleanroom environment, avoid outgassing contaminants under vacuum, and assess contaminant levels on payload optics. We present a detailed contamination budget through the mission end of life as well as our ongoing contamination monitoring efforts. We discuss protocols implemented for minimizing contamination-related performance degradation.

This research is supported by NASA Astrophysics Pioneers Program, Aspera Revealing the Diffuse Universe (80NSSC22M0081). Author Nicole Melso is supported by the Alan Brass Prize Postdoctoral Fellowship in Instrumentation and Technology Development. Co-author Aafaque Khan is a NASA FINNEST future investigator supported under grant number 80NSSC21K2050. Aspera builds upon previous UV missions that have developed in-depth contamination analysis, monitoring processes, and mitigation plans. This work has benefited significantly from studying the Solar Ultraviolet Imaging Telescope (SUIT) Contamination Control and Verification Plan authored by Aafaque Khan, Dr. Durgesh Tripathi, and Dr. A. N. Ramaprakash from Inter-University Center for Astronomy and Astrophysics, Pune, India. We thank Jim Green, Logan Jensen, and the ASU SPARCS team for helpful discussions that have helped shape our contamination control plan.
