A system has been developed and tested for real-time monitoring of environmentally-induced electrostatic discharge events to test spacecraft component and material survivability. Simultaneous detection by several parallel methods in coincidence, enhances event detection, minimizes false signals, and collects complementary information to determine arc location, intensity, and timing. This research focuses on four computer-interfaced video cameras which provide spatial and temporal detection of visual arcing from the surface of various elements. A real time processing solution was developed which can calculate integrated intensities, sensitively detect intensity threshold events, and store relevant video frames from these threshold events. Post processing of this …

Muscular atrophy is a serious issue for extended spaceflight. Understanding and preventing the role of ionizing radiation in skeletal muscle loss would preserve the strength and endurance of astronauts and enable longer duration space travel and exploration. Irradiation was performed in the USU material physics group's Space Suvivability Test Chamber. C2C12 and CRL-1999 cells were exposed to dosages ranging from 0.5 - 36.8 Gy. Cell viability and growth rate were measured immediately following irradiation.

It is a real challenge to reproduce various space environment conditions in ground-based facilities for testing of external space system materials and elements. This is due to the variety and complexity of the space environment conditions and their effects on materials and structures. The reliability of test results depends on accurate simulation of the critical factors and effects of the space environment for a particular mission. The main objectives of the simulation testing are to get the test results that are adequate to the material durability and functional behavior in a space environment.

As part of a large, multi-year program, …


Wireless Antenna Detection Of Electrostatic Discharge Events, Allen Andersen, Jr Dennison Jun 2018

Wireless Antenna Detection Of Electrostatic Discharge Events, Allen Andersen, Jr Dennison

Conference Proceedings

Wireless intra-spacecraft communication technology is being developed as a weight-saving and design-simplifying measure for signal transfer on space missions. One consideration for this new technology is its interaction with space-environment induced electrostatic discharges (ESD). The short time scales of spacecraft ESD events results in broad frequency signals that can interact with wireless antennae. These interactions present a source of signal noise. However, they may also present a possibility of in-flight wireless ESD monitoring.

We present laboratory measurements of arcing on common spacecraft insulators using commercially available single band 2.4 GHz and dual band 2.4/5.8 GHz Wi-Fi antennas. These wireless detections …
