Asteroid surface resource characterization through plasma analysis of meteoroid impact ejecta, Stanford University
Asteroids are constantly bombarded by much smaller meteoroids at extremely high speeds, which results in erosion of the material on the asteroid surface. Some of this material is vaporized and ionized, forming a plasma that is ejected into the environment around the asteroid where it can produce an effect on closely orbiting spacecraft.
We present a concept to leverage this natural phenomenon and to analyze this excavated material using low-power plasma sensors in order to build a map of the composition on the asteroid surface. This concept would enable a constellation of small satellites to provide useful data complementing existing techniques such as spectroscopy, which require larger and more power-hungry sensors. By using a cluster of small satellites rather than just one single spacecraft, the asteroid surface can be mapped more rapidly in order to determine if it is a suitable candidate for further activities such as asteroid mining.
