Project Description

The NASA Psyche mission plans to launch a spacecraft to visit and conduct a scientific investigation of the asteroid (16) Psyche in our solar system’s asteroid belt. The primary motivator of this mission is to test the hypothesis that (16) Psyche is the core of a planetesimal (the precursor to a fully formed planet). To prepare for scientific investigations at Psyche, meteorite scientists wish to analyze the bulk mineral composition of iron meteorite samples, including those in the large collections housed at ASU and the Smithsonian. Standard analysis techniques are labor intensive, prompting the need for improved methods. The Iron Meteorite Imaging System (IMIS) was developed to capture high quality images of prepared meteorite samples for composition analysis using techniques from computer vision and machine learning. Image capture presented several challenges, including supporting a wide variety of meteorite sample sizes, handling glare and overexposure, and the consistency and accuracy of images. A prototype IMIS was developed, addressing these issues to allow semi-automated image capture.This sets the stage for future work, specifically on having the system extract information on bulk composition of samples from images.
