The role of composition in the spectral evolution of carbonaceous asteroids as informed by Bennu sample return

|
By Ralph E. Milliken, Takahiro Hiroi, Victoria E. Hamilton
| Wiley Online Library Verified
INTRODUCTION Small bodies in the solar system are primarily categorized by their spectral reflectance properties at visible (VIS) and near-infrared (NIR) wavelengths (e.g., ~0.35–4 μm) (Bus & Binzel, 2002; DeMeo et al., 2009). Asteroids of the carbonaceous taxonomic complex (C-complex) are characterized by low albedo and are interpreted to have compositions similar to carbonaceous (C) chondrite meteorites (DeMeo et al., 2022; Feierberg et al., 1985; Hiroi et al., 1993; Johnson & Fanale, 1973).

Carbonate formation and fluctuating habitability on Mars - Nature

|
By Edwin Kite, Benjamin M. Tutolo, Thomas Bristow Verified, Ralph E. Milliken, Heather B. Franz
| Nature Verified
Abstract The cause of Mars’s loss of surface habitability is unclear, with isotopic data suggesting a ‘missing sink’ of carbonate1. Past climates with surface and shallow-subsurface liquid water are recorded by Mars’s sedimentary rocks, including strata in the approximately 4-km-thick record at Gale Crater2.
