OSIRIS-REx Spacecraft Assembly Nearly Complete

The OSIRIS-REx mission continues to make great progress. As I have mentioned before, we are in the Assembly, Test, and Launch Operations (ATLO) phase of the program. We have had many great accomplishments leading up to this point. At the heart of our mission is the Sample Acquisition and Return Assembly (SARA). This assembly contains […]

Populating the OSIRIS-REx Science Deck

The assembly of the OSIRIS-REx spacecraft continues, with many elements integrated onto the spacecraft ahead of schedule. Last month both OTES and OVIRS were delivered to Lockheed Martin and installed on the science deck. OTES had the honor of being the first science instrument to be placed on the spacecraft. Both OTES and OVIRS came […]

A Visit to the ATLO Floor

Last month I finally got up close and personal with the OSIRIS-REx spacecraft. I am now making regular visits to the Lockheed Martin Space Systems facility in Littleton, Colorado, where OSIRIS-REx is under construction. However, during most of these visits, I only get to see the spacecraft from the viewing gallery on the third floor, […]

OSIRIS-REx – Testing In Progress

The OSIRIS-REx spacecraft is in the assembly and testing phase at Lockheed Martin’s facility outside of Denver, Colorado. The instruments have begun to arrive at the facility, with OTES and OVIRS being delivered in the past weeks. While the OLA, OCAMS, and REXIS instruments continue working towards their deliveries, other hardware onsite at Lockheed is undergoing testing […]

Development of the OSIRIS-REx Sampling System: TAGSAM and the SRC

In addition to continued progress in the building the OSIRIS-REx spacecraft and scientific instruments, the team at Lockheed Martin has been busy assembling and testing two key components of the system. The Touch-and-Go Sample Acquisition Mechanism (TAGSAM) is the device that satisfies all sample-acquisition requirements. TAGSAM consists of two major components: a sampler head and […]

OSIRIS-REx Begins ATLO (Assembly, Test, and Launch Operations)!

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. […]

How Do We Know When We Have Collected a Sample of Bennu?

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 – […]

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 […]

Integration of the OSIRIS-REx Main Propellant Tank

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 […]
