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 […]

OSIRIS-REx – Day 2 in Space

       Our spacecraft continues to operate flawlessly. Kudos to the operations team members who have been tracking and operating the spacecraft since separation! 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 […]

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 […]

Celebrating the Small Bodies of the Solar System – i C Ceres!

This past weekend, I had the chance to join colleagues from across the country to celebrate the arrival of the Dawn spacecraft at Dwarf Planet/Asteroid 1 Ceres – the largest object in the main asteroid belt. After more than seven years cruising through the solar system, including an amazing year exploring asteroid 4 Vesta, Dawn […]

The OSIRIS-REx Heavy Launch Opportunity

As recent press articles have discussed, the OSIRIS-REx team has been busy performing a special study related to our launch mass and propellant load. The objective of this study is to look at ways to increase the OSIRIS-REx spacecraft delta-V capability as much as possible without impacting the current spacecraft or launch vehicle designs. Delta-V […]

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 […]

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 Laser Altimeter (OLA) – Our Measuring Tool

Guest Blogger:Michael Daly – OLA Instrument Scientist, York University The OSIRIS-REx mission will visit the carbonaceous near-Earth asteroid Bennu in 2018 and bring back a sample for analysis in Earth-based laboratories in 2023. In order to understand where the sample comes from as well as to select a sample site, the spacecraft has a number […]
