TL;DR: The OSIRIS-REx spacecraft departed for near-Earth asteroid (101955) Bennu via an United Launch Alliance Atlas V 411 evolved expendable launch vehicle at 7:05 p.m. EDT on September 8, 2016, on a seven-year journey to return samples from Bennu as discussed by the authors.

TL;DR: Spectral observations and a principal components analysis suggest that Ryugu originates from the Eulalia or Polana asteroid family in the inner main belt, possibly via more than one generation of parent bodies.

TL;DR: The Hayabusa2 mission as mentioned in this paper was the first mission to explore a C-type near-Earth asteroid (162173) Ryugu (1999 JU3) to observe and explore the 900 m-sized object, and return samples collected from the surface layer.

Debiased orbit and absolute-magnitude distributions for near-Earth objects
Mikael Granvik,Alessandro Morbidelli,Robert Jedicke,Bryce Bolin,William F. Bottke,E. C. Beshore,David Vokrouhlický,David Nesvorný,Patrick Michel +8 more
TL;DR: In this article, the authors presented a new four-dimensional model of the near-Earth objects population that describes debiased steady-state distributions of semimajor axis, eccentricity, inclination, and absolute magnitude H in the range 17.962 − 56 + 52 + 52 ( 802 − 42 + 48 × 10 3 ) NEOs with H.

Asteroid family ages
TL;DR: In this paper, a catalog of proper elements with ∼384,000 numbered asteroids and on new methods is available, including a least squares fit of the two sides of a V-shape plot in the proper semimajor axis, inverse diameter plane to determine the corresponding slopes, an advanced error model for the uncertainties of asteroid diameters, an iterative outlier rejection scheme and quality control.

Thermal Evolution Models of Asteroids
TL;DR: In this article, the authors compared thermal evolution models for asteroids that experienced metamorphism (ordinary chondrites), aqueous alteration (carbonaceous chondites), and melting and differentiation (HED achondrites) based on decay of 26Al.

TL;DR: Using albedos from WISE/NEOWISE to separate distinct albedo groups within the Main Belt asteroids, the authors apply the Hierarchical Clustering Method to these subpopulations and identify dynamically associated clusters of asteroids.

TL;DR: In this paper, the authors present analysis of thermal infrared photometry and spectroscopy that test the hypotheses that Bennu is carbonaceous and that its surface is covered in fine-grained (sub-cm) regolith.

TL;DR: In this paper, an updated list of observed asteroid families as identified in the space of synthetic proper elements by the hierarchical clustering method, colour data, albedo data and dynamical considerations is presented.

Pairs of asteroids probably of a common origin
TL;DR: In this article, the first observational evidence for pairs of main-belt asteroids with bodies in each pair having nearly identical orbits was reported, and the existence of ~60 pairs identified here cannot be reconciled with random fluctuations of the asteroid orbit density and rather suggests a common origin of the paired objects.
