Traces Of Ancient Brine Discovered On Asteroid Bennu Contain Minerals Crucial To Life
A new analysis of samples from the asteroid Bennu, NASA’s first asteroid sample captured in space and delivered to Earth, reveals that evaporated water left a briny broth where salts […]
Asteroid Bennu Sample Reveals A Mix Of Life’s Ingredients
Studies of rock and dust from asteroid Bennu delivered to Earth by NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification and Security–Regolith Explorer) spacecraft have revealed molecules that, on our planet, […]
A Broad Set of Solar and Cosmochemical Data Indicates High C-N-O Abundances For Our Solar System
We examine the role of refractory organics as a major C carrier in the outer protosolar nebula and its implications for the compositions of large Kuiper belt objects (KBOs) and […]
Meteoritic Tutton Salt, A Naturally Inspired Reservoir Of Cometary And Asteroidal Ammonium
The lack of benchmark data on the real minerals, native ammonium carriers in Solar System gives rise to controversial opinions on extraterrestrial ammonium reservoirs.
Geophysical Observations Of OSIRIS-REx Sample Return Capsule Re-Entry
Sample Return Capsules (SRCs) entering Earth’s atmosphere at hypervelocity from interplanetary space are a valuable resource for studying meteor phenomena.
Asteroid Bennu: Properties Of The Sample Collected By OSIRIS-REx
On September 24, 2023, NASA’s OSIRIS-REx mission dropped a capsule to Earth containing ~120 g of pristine carbonaceous regolith from Bennu. We describe the delivery and initial allocation of this asteroid […]
Source Regions of Carbonaceous Meteorites and NEOs
The present work aims to determine the source regions of carbonaceous chondrites (CM, CI, CO, CV, CK, CR, CH, CB, or C-ungrouped). We studied 38 individual asteroid families, including young […]
An OSIRIS-REx Asteroid Sample Has Surprising Phosphate Content
Scientists have eagerly awaited the opportunity to dig into the 4.3-ounce (121.6-gram) pristine asteroid Bennu sample collected by NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer) […]
OSIRIS-REx Asteroid Samples Now Available to World’s Scientists
Scientists outside of NASA’s OSIRIS-REx team are getting their first close look at the asteroid Bennu samples available for independent research just six months after their delivery to Earth.
