Lauretta D, Adam C, Allen A, Ballouz R, Barnouin O, Becker K, et al.
Science
. 2022 Jul;
377(6603):285-291.
PMID: 35857591
Carbonaceous asteroids, such as (101955) Bennu, preserve material from the early Solar System, including volatile compounds and organic molecules. We report spacecraft imaging and spectral data collected during and after...

Nature
. 2021 Oct;
598(7879):49-52.
PMID: 34616055
Spacecraft missions have observed regolith blankets of unconsolidated subcentimetre particles on stony asteroids. Telescopic data have suggested the presence of regolith blankets also on carbonaceous asteroids, including (101955) Bennu and...

Ballouz R, Walsh K, Barnouin O, DellaGiustina D, Asad M, Jawin E, et al.
Nature
. 2020 Oct;
587(7833):205-209.
PMID: 33106686
An asteroid's history is determined in large part by its strength against collisions with other objects (impact strength). Laboratory experiments on centimetre-scale meteorites have been extrapolated and buttressed with numerical...

DellaGiustina D, Burke K, Walsh K, Smith P, Golish D, Bierhaus E, et al.
Science
. 2020 Oct;
370(6517).
PMID: 33033157
Visible-wavelength color and reflectance provide information about the geologic history of planetary surfaces. Here we present multispectral images (0.44 to 0.89 micrometers) of near-Earth asteroid (101955) Bennu. The surface has...

Kaplan H, Lauretta D, Simon A, Hamilton V, DellaGiustina D, Golish D, et al.
Science
. 2020 Oct;
370(6517).
PMID: 33033155
The composition of asteroids and their connection to meteorites provide insight into geologic processes that occurred in the early Solar System. We present spectra of the Nightingale crater region on...

Rozitis B, Ryan A, Emery J, Christensen P, Hamilton V, Simon A, et al.
Sci Adv
. 2020 Oct;
6(41).
PMID: 33033037
Thermal inertia and surface roughness are proxies for the physical characteristics of planetary surfaces. Global maps of these two properties distinguish the boulder population on near-Earth asteroid (NEA) (101955) Bennu...

Molaro J, Walsh K, Jawin E, Ballouz R, Bennett C, DellaGiustina D, et al.
Nat Commun
. 2020 Jun;
11(1):2913.
PMID: 32518333
Rock breakdown due to diurnal thermal cycling has been hypothesized to drive boulder degradation and regolith production on airless bodies. Numerous studies have invoked its importance in driving landscape evolution,...

Lauretta D, Hergenrother C, Chesley S, Leonard J, Pelgrift J, Adam C, et al.
Science
. 2019 Dec;
366(6470).
PMID: 31806784
Active asteroids are those that show evidence of ongoing mass loss. We report repeated instances of particle ejection from the surface of (101955) Bennu, demonstrating that it is an active...

Nat Geosci
. 2019 May;
12(4):247-252.
PMID: 31080497
The shapes of asteroids reflect interplay between their interior properties and the processes responsible for their formation and evolution as they journey through the Solar System. Prior to the OSIRIS-REx...

PMID: 30890786
NASA'S Origins, Spectral Interpretation, Resource Identification and Security-Regolith Explorer (OSIRIS-REx) spacecraft recently arrived at the near-Earth asteroid (101955) Bennu, a primitive body that represents the objects that may have brought...
