OSIRIS-REx – What’s in a Name?

The Art Project Today we officially unveiled the mural celebrating the University of Arizona-led OSIRIS-REx mission. To create this public art, we teamed up with the students of Professor Alfred Quiroz’s fall semester mural painting class at the UA School of Art. Between August and December 2014, the students worked together to produce this great […]

The YORP Effect and Bennu

As I have discussed in an earlier post, one of the OSIRIS-REx mission’s top objectives is to understand the Yarkovsky effect. The Yarkovsky effect describes a small force that affects the orbit of asteroids. In the 19th century, Ivan Yarkovsky realized that the infrared radiation escaping from a body warmed by the Sun carries off […]

Bennu's Journey is a 6-minute animated movie about NASA's OSIRIS-REx mission, asteroid Bennu, and the formation of our solar system.

The Science of “Bennu’s Journey”

This week the OSIRIS-REx project released Bennu’s Journey, a movie describing one possible history of our target asteroid – Bennu. The animation is among the most highly detailed productions created by Goddard’s Conceptual Image Laboratory. It is the result of an exciting collaboration between the OSIRIS-REx Science Team, Walt Feimer and Michael Lentz, from the […]

Collaboration Between OSIRIS-REx and Hayabusa-2

On October 3rd, 2014, the University of Arizona (UA) hosted representatives of the Hayabusa-2 asteroid sample return mission to explore opportunities for collaboration with the OSIRIS-REx team. Following an invitation from UA President Ann Weaver Hart, a team led by Dr. Saku Tsuneta, Director General of the Institute of Space and Astronautical Science (ISAS) of the […]

All That is Known About Bennu

Today, we released the OSIRIS-REx Design Reference Asteroid (DRA) document to the public. The DRA is a compilation of all that is known about the OSIRIS-REx mission target, asteroid (101955) Bennu. We are making this document available as a service to future mission planners in the hope that it will inform their efforts. The DRA […]

REXIS: X-ray Vision for OSIRIS-REx

Guest Bloggers: Mark Chodas (REXIS Student Team Members) and Richard P. Binzel (REXIS-PI) When the OSIRIS-REx spacecraft arrives at the target near-Earth asteroid Bennu, its first science task is to globally characterize the nature and composition of the asteroid surface. This characterization is all driven toward the selection among safe and enticing sampling sites for […]

The Osirian Asteroid Family

Asteroid Families Defined The asteroid community recently gathered in Helsinki, Finland for the 12th Asteroids, Comets, and Meteors Conference. As this meeting showed, one of the hottest topics in asteroid science is the study of asteroid families. The majority of asteroids orbit the Sun between Mars and Jupiter. As a century of research has shown, […]

OSIRIS-REx at the 2014 Asteroids, Comets, and Meteors Conference

  I just recently returned from a trip to Helsinki, Finland to attend the 12th Asteroids, Comets, and Meteors Conference. The ACM conference focuses on the research of small Solar System bodies and their role in understanding the formation and evolution of the Solar System. Topics range from the evolution of extrasolar planetary systems to […]

Osirians of the Great White North – The Canadian Contribution to OSIRIS-REx

Co-authored with Lori Stiles When we first started planning an asteroid sample-return mission for the NASA New Frontiers Program, we looked to the Canadian Space Agency (CSA) to provide the OLA instrument for topographic mapping and ranging to the asteroid. We also sought Co-Investigators from Canada to help us study the geology of our target […]

The OSIRIS-REx Design Reference Mission – Our Battle Plan

This week the OSIRIS-REx team gathered at the Lockheed Martin facility in Denver to perform a “Design Reference Mission (DRM)” walkthrough. The DRM is basically the battle plan for OSIRIS-REx for accomplishing our goal of returning pristine samples from asteroid Bennu. In addition, the DRM lays out our basic strategy for dealing with any problems […]
