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 […]

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 […]

Two Years to Launch – Another moment to reflect…

Today marks exactly two years to the opening of the OSIRIS-REx launch window on September 3, 2016. These milestones are always a good time to reflect on the progress to date and the work going forward. Josh Wood, our Flight System Engineer at Lockheed Martin sent out a great email to the team that provides […]

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 […]

Highlights from OSIRIS-REx Science Team Meeting #6

The OSIRIS-REx Science Team gathered at the University of Arizona in Tucson from April 22 -24, 2014 for their sixth meeting. The meeting was a dynamic event and covered many aspects of both the science and implementation of the mission. In this post I will discuss a few of the highlights. In Search of the […]

DEWG – Where’s my Asteroid?

The OSIRIS-REx mission is driven by five major science objectives. One of these objectives is to “Understand the interaction between asteroid thermal properties and orbital dynamics by measuring the Yarkovsky effect on a potentially hazardous asteroid [Bennu] and constrain the asteroid properties that contribute to this effect.” Read on to find out what this means […]
