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 […]

The SARA panel, containing both TAGSAM and the SRC was installed on the OSIRIS-REx spacecraft this month. Note the harnesses dropping the panel in. The SRC and TAGSAM are bagged to maintain cleanliness and ensure return of a pristine sample.

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 […]

Two years to launch!

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 […]

During Detailed Survey we generate the mineralogical and thermal maps of Bennu using OVIRS and OTES

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 […]

The OSIRIS-REx spacecraft structure marks the beginning of building the system that will fly to Bennu.

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 Thermal Emission Spectrometer (OTES) – Our Heat Sensor and Mineral Mapper

Guest Blogger: Vicky Hamilton, OTES Deputy Instrument Scientist To help characterize the asteroid Bennu and aid in the selection of a scientifically compelling sampling site, OSIRIS-REx carries a pair of complementary spectrometers, one of which is called the OSIRIS-REx Thermal Emission Spectrometer, or OTES. OTES is being developed and built at the School of Earth […]
