OSIRIS-REx Completes Mechanical Environmental Testing

The OSIRIS-REx spacecraft continues to progress smoothly through the Assembly, Test, Launch and Operations (ATLO) process. This past month, the team successfully and safely completed sine vibration (sine vibe) testing prior to the Thanksgiving holiday. The sine vibe tests are designed to verify the system performs as expected after being exposed to flight-like low frequency […]

OSIRIS-REx Progressing Through Environmental Testing

Our spacecraft continues to make steady progress toward launch in September 2016. During the final stages of assembly, OSIRIS-REx completed final installation of the High Gain Antenna and completed solar array installation. After integrating these components, we completed a solar array illumination test on both arrays. The Spacecraft then passed a cleaning check and was […]

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 – […]

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 […]
