Characterizing Primitive Asteroids Primitive classes of asteroids, namely those of the B, P, D and C-complex types, are not well characterized in terms of surface composition due to a lack of diagnostic spectral features at visible-near infrared (VNIR) wavelengths. This presents a critical problem because these are important objects due to their primitive nature and their links to early solar system processes. Indeed, the upcoming Lucy mission will visit C-type asteroid Donaldjohanson and several Trojan asteroids (P and D type asteroids). However, despite a lack of spectral features at VNIR wavelengths, these objects do exhibit varying strengths of UV absorption, as observed by the International Ultraviolet Explorer (IUE), which may be related to volatile abundance and thermal history. We propose to observe 6 low-albedo class main belt asteroids to characterize them in terms of their UV spectral shape. We will test the hypothesis that a spectral trend with heliocentric distance should be present, based on the changing thermal and compositional environment. This program will observe 6 outer main belt asteroid targets using STIS, with one target per orbit/visit. Each visit will include two exposures: one longer exposure using G230L/MAMA and a shorter one using G430L/CCD. The CCD exposures will use offset pointing for CTE mitigation. Dr. Amanda Hendrix has experience in HST STIS observation planning and data reduction. Dr. Hendrix is an expert in UV spectroscopy of planetary surfaces and has led and participated in several HST observing campaigns, studying UV-visible spectra of Ceres, Europa, Trojan asteroids, Enceladus/Mimas/Dione/Rhea, Iapetus, Saturn's rings and Io, with publications in print or in preparation on all programs. Dr. Faith Vilas has extensive expertise on asteroids, particularly primitive/low-albedo class asteroids. She has partnered with Dr. Hendrix on HST/STIS Ceres observations and analyses as well as ground-based observations of asteroids.
