Summary of Research
My research focuses on studying the effects of microscopic meteoroids and space debris particles as they impact spacecraft at extremely high velocities (7-72 km/s). These particles are too small to cause mechanical damage. However, at these high velocities the impactor vaporizes and generates a plasma plume that can create radio frequency emissions and electromagnetic pulses as it expands outwards, potentially damaging spacecraft electronics. This plume transitions from a warm dense matter state to a collisionless plasma as it expands into the vacuum.
My goal is to computationally model the impact and expansion phases to better understand the underlying physics of how these impacts may threaten spacecraft. In particular, I am interested in how the plasma interacts with dust particles present in the space environment, many of which are on similar scales as the impactor, to see what role dusty plasma effects play.
