Searching for the Earth-Trojan Asteroids

The OSIRIS-REx mission will take advantage of our fortuitous trajectory to search for an elusive class of asteroids that may be the remnants of the building blocks of the Earth. Since our launch on September 8, 2016, spacecraft operations for OSIRIS-REx have gone well. We have exercised the propulsion system by performing regular momentum dumps […]

OSIRIS-REx Spacecraft Check Out and Early Cruise Phase Activities

It has been awhile since I posted anything to this site. The launch of OSIRIS-REx was such an amazing, emotional experience; it took me about a month to come back down to Earth (pun intended). I have now settled into a normal work routine in Tucson and the team has been busy operating the spacecraft […]

Here are some details on recent status.      After a flawless launch day, day 2 has also progressed as planned.      We have completed the Countup Procedure and the spacecraft has […]

What Would Happen if Asteroid Bennu Were to Impact the Earth?

Yesterday, the media reported widely on the upcoming launch of OSIRIS-REx. While many of these reports were accurate and informative, a few of the headlines were a little misleading. For example: NASA Spacecraft Set to Explore Giant Asteroid That Could Destroy Earth Fortunately, as the news cycle progressed, these inaccuracies were corrected: No, Asteroid Bennu […]

39 Days to Launch – What’s Left to Get Done?

With only 39 days to go until we launch OSIRIS-REx our schedule is packed with activities. Here is a quick rundown of what the team has left to do to get ready to blast this asteroid-sampling robot into space. 8/2: Mission Event Readiness Review – DSN/JPL The Deep Space Network (DSN) is a critical component […]

OSIRIS-REx Passes EMI/EMC Testing

The OSIRIS-REx spacecraft has completed the Electromagnetic Interference/Electromagnetic Compatibility (EMI/EMC) system level test. This test has three objectives. The first objective is to test for Radiated Emissions, which are the release of electromagnetic energy from the spacecraft. To pass this test, the team had to verify that the emissions from the Spacecraft do not violate […]

The Difficulties with Predicting Armageddon

In February of 2013, the science community’s eyes were glued to the sky. They were watching for asteroid Duende, a 30m lump of rock that was due to skim past our planet in a record close approach for an object of its size. And while everyone stared skywards in one direction, another rock shot in […]

The Target Asteroids! Citizen Science Program

Imagine… Imagine turning a mere point of light into a real world! That is what Target Asteroids! observers do when they submit images and data to the OSIRIS-REx mission’s citizen science program. These observations allow the OSIRIS-REx science team and other planetary scientists to better understand our target, Potentially Hazardous Asteroid (PHA) (101955) Bennu, and […]
