The Hayabusa-2 mission shares many common goals with OSIRIS-REx.

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 […]

These figures show the slope distribution on the surface of Bennu. This information provides confidence that loose regolith can accumulate at the equator.

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 […]

The static test fixture is a series of vices, which push and pull on the structure to simulate the loads that the spacecraft will experience during launch.

OSIRIS-REx Spacecraft Passes First Major Qualification Test

The development of the OSIRIS-REx spacecraft continues to make great progress. When I last reported on the status of the vehicle, we were preparing to deliver the structure to Lockheed Martin’s Structures Test Lab to undergo static load testing. I am happy to report that the Static Test is complete! The last load case was […]

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 color of asteroids helps determine which family they belong to.

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 […]

During Detailed Survey we generate the mineralogical and thermal maps of Bennu using OVIRS and OTES

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 […]

The OSIRIS-REx spacecraft structure marks the beginning of building the system that will fly to Bennu.

Spacecraft Structure – The Bones of OSIRIS-REx

Last month, I had the opportunity to visit the spacecraft composite fabrication lab at Lockheed Martin’s Space Systems Company facility near Denver. The construction of OSIRIS-REx has begun! The first flight components include the spacecraft structural parts – basically the skeleton of our spacecraft upon which all other components will be mounted. Spacecraft structures have […]

The OSIRIS-REx Visible and near-IR Spectrometer (OVIRS) – Measuring the chemistry and reflectance of Bennu

Guest Blogger: Amy Simon – OVIRS Deputy Instrument Scientist OSIRIS-REx will map the entire surface of asteroid Bennu to pick a site that is most accessible and likely to yield a sample, but is also scientifically interesting. Choosing the best site requires understanding both the local geology and the local composition; a prime goal of […]
