The System Integration Review was the last major technical review leading up to the KDP-D decision.

Yesterday, the OSIRIS-REx mission passed another major milestone – successfully completing Key Decision Point “D” (KDP-D). This decision point is one of five key milestones that we pass through leading up to launch. KDP-D occurred after we had completed a series of independent reviews that cover the technical readiness, schedule, and cost of the project. […]

Guest Blogger: Dolores Hill Who in the world? Who in the world would spend their free time talking to the public about the OSIRIS-REx mission and asteroids? OSIRIS-REx Ambassador volunteers and OSIRIS-REx team members! We are privileged to have a great team of volunteers who staff tables at public events such as the University of […]

Guest Blogger: Kevin Walsh A huge amount of effort goes into deciding where to try to collect a sample on Bennu. There are roughly nine months to survey, map and model the asteroid to help make this decision, and I will describe some of the important factors of that decision below. Just as important – […]

Guest Blogger: Ed Beshore Dante has written extensively here about the science we hope to accomplish both at Bennu and when we return a sample to the Earth. He and other guest columnists like me have also discussed the design and construction of the OSIRIS-REx spacecraft and its instruments (OCAMS, OLA, OVIRS, OTES, and REXIS). […]

Fire at Highland Plating on July 13.

Guest Bloggers: Jason Hair, Dennis Reuter, and Amy Simon Building a mission or an instrument is not for the faint of heart. While engineering teams develop plans to avoid major mishaps, sometimes even the best laid plans aren’t enough. A case in point is a series of unfortunate events that happened to the OVIRS instrument […]

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 […]

The UA College of Science presents seven free lectures on "Life in the Universe". This series explores our Universe at molecular, biological, planetary and cosmic scales to ask "What is life?" and how do we recognize it?

On Monday, February 2, 2015, I will present the UA College of Science Lecture on “Planet Formation and the Origin of Life”. This is a research theme that I have pursued for most of my career. It is generally accepted that planets or their satellites are required for life to originate and evolve. Thus, in […]

The OSIRIS-REx mural now graces the west wall of the Michael J. Drake building at the University of Arizona.

The Art Project Today we officially unveiled the mural celebrating the University of Arizona-led OSIRIS-REx mission. To create this public art, we teamed up with the students of Professor Alfred Quiroz’s fall semester mural painting class at the UA School of Art. Between August and December 2014, the students worked together to produce this great […]

The WordPress.com stats helper monkeys prepared a 2014 annual report for my blog. Here’s an excerpt: The concert hall at the Sydney Opera House holds 2,700 people. This blog was viewed about 18,000 times in 2014. If it were a concert at Sydney Opera House, it would take about 7 sold-out performances for that many […]

Completion of the OSIRIS-REx main propellant tank integration with the spacecraft structure.

The assembly of the OSIRIS-REx spacecraft continues to make excellent progress. Most notably, this month Lockheed Martin installed the main propellant tank on the OSIRIS-REx spacecraft at their Space Systems Company facility near Denver, Colorado. In addition to the large tank, many of the primary propulsion components are in house and undergoing extensive testing and […]
