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 […]

OSIRIS-REx Passes EMI/EMC Testing

The OSIRIS-REx spacecraft has completed the Electromagnetic Interference/Electromagnetic Compatibility (EMI/EMC) system level test. This test has three objectives. The first objective is to test for Radiated Emissions, which are the release of electromagnetic energy from the spacecraft. To pass this test, the team had to verify that the emissions from the Spacecraft do not violate […]

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. […]

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 […]

From the Desert to Space

In my last post, guest blogger Bashar Rizk described the three cameras of the OSIRIS-REx Camera Suite (OCAMS). These imagers will provide unprecedented documentation of Bennu’s size, shape, geology, and environment. Have you ever wondered how those images, taken on board the OSIRIS-REx spacecraft, get back down to Earth? Read on to learn about the […]
