When optical navigation images acquired by the OSIRIS‐REx (Origins, Spectral Interpretation, Resource Identification, and Security‐Regolith Explorer) mission revealed the periodic ejection of particles from asteroid (101955) Bennu, it became a mission priority to quickly identify and track these objects for both spacecraft safety and scientific purposes. The large number of particles and the mission criticality rendered time‐intensive manual inspection impractical. We present autonomous… 

MONITORING THE OPERATIONAL ENVIRONMENT OF ACTIVE ASTEROID (101955) BENNU

The OSIRIS-REx spacecraft has observed the release of small particles from the surface of asteroid (101955) Bennu. New techniques and tools have been developed to detect, track, and characterize the

INDEPENDENT OPTICAL NAVIGATION PROCESSING FOR THE OSIRIS-REX MISSION USING THE GODDARD IMAGE ANALYSIS AND NAVIGATION TOOL

The OSIRIS-REx mission to the asteroid (101955) Bennu heavily relies on optical navigation to provide relative state information between the asteroid and the spacecraft. These measurements enable

Initial Orbit Determination and Event Reconstruction From Estimation of Particle Trajectories About (101955) Bennu

Current results pertaining to the identification of particle tracks, an evaluation of the estimated orbits and the excess velocity necessary to induce the particle ejection from the surface, and the uncertainty quantification of the ejection location are presented.

Reconstruction of Bennu Particle Events From Sparse Data

This newly developed technique offers the capacity to meaningfully constrain the properties of particle ejection events from limited data and comparison with higher‐fidelity orbit determination solutions for the events with sufficient observations demonstrates the validity of this approach.

Introduction to the Special Issue: Exploration of the Activity of Asteroid (101955) Bennu

Of the potential mechanisms behind this activity that were investigated in focused studies, meteoroid impacts, thermal fracturing, and ricochet—but not water ice sublimation—were found to be consistent with observations, suggesting that many near‐Earth asteroids may exhibit activity that has gone unnoticed thus far.

Trajectory Estimation for Particles Observed in the Vicinity of (101955) Bennu

We analyze the trajectories of 313 particles seen in the near‐Bennu environment between December 2018 and September 2019. Of these, 65% follow suborbital trajectories, 20% undergo more than one

A Bibliometric Perspective Survey of Astronomical Object Tracking System

The survey and bibliometric analysis of Astronomical Object Tracking from the Scopus database is discussed in analyzing the research by area, influential authors, institutions, countries, and funding agency.

Mass and Shape Determination of (101955) Bennu Using Differenced Data from Multiple OSIRIS-REx Mission Phases

The Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer (OSIRIS-REx) mission collected a sample from the rubble-pile asteroid (101955) Bennu for return to Earth.

Photometry of Particles Ejected From Active Asteroid (101955) Bennu

Near‐Earth asteroid (101955) Bennu is an active asteroid experiencing mass loss in the form of ejection events emitting up to hundreds of millimeter‐ to centimeter‐scale particles. The close

IN-FLIGHT CALIBRATION OF THE OSIRIS-REX OPTICAL NAVIGATION IMAGERS

Navigation for solar system exploration missions often requires optical navigation techniques in order to achieve the orbit determination precision necessary to fulfill mission science objectives.

Episodes of particle ejection from the surface of the active asteroid (101955) Bennu

The properties and behavior of particles ejected from Bennu are analyzed to determine the possible mechanisms of ejection and provide understanding of the broader population of active asteroids.

Use Of A Scanning Ccd To Discriminate Asteroid Images Moving In A Field Of Stars

We are using a charge-coupled device (CCD) in a scanning mode to find new asteroids and recover known asteroids and comet nuclei. Current scientific programs include recovery of asteroids and comet

Near‐Earth Asteroid Tracking (NEAT) Program

ABSTRACT: The discoveries of near‐Earth asteroids (NEAs) and comets have increased enormously over the last 10–20 years. This is a consequence, in large part, of the success of programs that have

A grid algorithm for autonomous star identification

An autonomous star identification algorithm is described that is simple and requires less computer resources than other such algorithms and compares very favorably with other algorithms in the literature.

The dynamic geophysical environment of (101955) Bennu based on OSIRIS-REx measurements

Combining the measured Bennu mass and shape obtained during the Preliminary Survey phase of the OSIRIS-REx mission, a notable transition is found in Bennu’s surface slopes within its rotational Roche lobe, defined as the region where material is energetically trapped to the surface.
