Research Topic Description, including Problem Statement:
More than half of all satellite electrical failures remain unexplained. One possible cause could be micrometeoroid and orbital debris hypervelocity impact (HVI) on satellites. Beyond any physical damage that impact might cause, an HVI forms an ionized plasma near the spacecraft. Recent studies have shown this plasma generates radio frequency (RF) electromagnetic pulses (EMPs) potentially capable of causing catastrophic electrical damage to spacecraft and their components. The RF radiation can cause a high energy, short duration electrical field several orders of magnitude larger than spacecraft are typically designed to withstand. It is feasible that a large EMP incident could cripple or even completely disable a satellite. The ability to detect and characterize HVI-induced EMPs on-orbit would inform satellite design.
This investigation could include designing simulations and experiments for the purpose of characterizing:
RF field radiation produced by impact type – metal to metal, paint to plastic, meteoroid to solar panel or radiator, etc.
Variability of RF strength and duration produced by different velocities and sizes of high velocity impacts.
Near and far field strength and possible spacecraft effects of the RF spectrum emitted by different categories (e.g., sizes and material combinations) of impacts.
Other environmental effects including RF propagation, thermal, plasma density, plasma content, and other characteristics especially in different orbital regimes (i.e., LEO, HEO, GEO, MEO, etc.)
