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. […]

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 […]

OSIRIS-REx Spacecraft Passes First Major Qualification Test

The development of the OSIRIS-REx spacecraft continues to make great progress. When I last reported on the status of the vehicle, we were preparing to deliver the structure to Lockheed Martin’s Structures Test Lab to undergo static load testing. I am happy to report that the Static Test is complete! The last load case was […]

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 […]

The OSIRIS-REx Design Reference Mission – Our Battle Plan

This week the OSIRIS-REx team gathered at the Lockheed Martin facility in Denver to perform a “Design Reference Mission (DRM)” walkthrough. The DRM is basically the battle plan for OSIRIS-REx for accomplishing our goal of returning pristine samples from asteroid Bennu. In addition, the DRM lays out our basic strategy for dealing with any problems […]

Spacecraft Structure – The Bones of OSIRIS-REx

Last month, I had the opportunity to visit the spacecraft composite fabrication lab at Lockheed Martin’s Space Systems Company facility near Denver. The construction of OSIRIS-REx has begun! The first flight components include the spacecraft structural parts – basically the skeleton of our spacecraft upon which all other components will be mounted. Spacecraft structures have […]

The OSIRIS-REx Visible and near-IR Spectrometer (OVIRS) – Measuring the chemistry and reflectance of Bennu

Guest Blogger: Amy Simon – OVIRS Deputy Instrument Scientist OSIRIS-REx will map the entire surface of asteroid Bennu to pick a site that is most accessible and likely to yield a sample, but is also scientifically interesting. Choosing the best site requires understanding both the local geology and the local composition; a prime goal of […]

A Successful Critical Design Review!

Yesterday marked the final day of the OSIRIS-REx Critical Design Review (CDR). This review began on April 1, 2014 and spanned nine days – with one day off in the middle. Over 60 OSIRIS-REx team members presented almost 1,600 PowerPoint charts in 56 hours. Since a CDR is required for all elements (i.e., spacecraft, instruments, […]
