The Rosetta Mission’s Philae Landing – An OSIRIS-REx Perspective

Yesterday, the European Space Agency (ESA) made planetary exploration history. Rosetta became the first mission to successfully land a spacecraft on the surface of a comet. The Philae lander detached from Rosetta on November 12, 2014 at 08:35 UTC and landed seven hours later at 15:35 (8:35 am in Tucson). A confirmed landing signal was […]

The Art of Planetary Science

On October 17-19, 2014, the Lunar and Planetary Laboratory on the University of Arizona campus hosted the second annual Art of Planetary Science exhibition. I have always viewed scientific endeavors as having an artistic component. Through our work, scientists seek to understand the nature of our Universe and the laws that govern its evolution. We […]

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.
