The daily launch window is almost two hours long, extending to 9:00 pm EDT. The entire launch window is 34 days long, extending through October 11, 2016. We certainly hope we […]

As the excitement to the OSIRIS-REx launch builds up, the Tucson community has rallied in support of the mission. Somehow my summer research program was leaked out – creating new margarita recipes! Every summer I embark on a new journey to create a delicious and relaxing drink. Several of the drinkeries around town have requested […]


Yesterday, the media reported widely on the upcoming launch of OSIRIS-REx. While many of these reports were accurate and informative, a few of the headlines were a little misleading. For example: NASA Spacecraft Set to Explore Giant Asteroid That Could Destroy Earth Fortunately, as the news cycle progressed, these inaccuracies were corrected: No, Asteroid Bennu […]


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 […]

The OSIRIS-REx project continues to progress seamlessly through the Assembly, Test, and Launch Operations (ATLO) phase. We are now done with the AT portion of this phase and have started LO. The test phase ended with the completion of the last major environmental test: the thermal vacuum test. With the test program complete, the team […]


Guest Blogger:  Bradley Williams It was a chilly December morning; I was 10 years old and sitting on the cold, hard floor of my elementary school library … too enthralled and focused on a 20-inch television screen to realize how uncomfortable I was.  The TV was showing a live stream of Entry, Decent, and Landing […]

Testing for electromagnetic interference/electromagnetic compatibility (EMI/EMC) testing on the OSIRIS-REx spacecraft at Lockheed Martin.

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 […]

REXIS was repaired and certified to "do-no-harm" to the spacecraft.

OSIRIS-REx has achieved many major milestones over the past month. Of the more significant accomplishments is the installation of the Regolith X-ray Imaging Spectrometer (REXIS) on the spacecraft. The instrument team has successfully installed the REXIS Spectrometer and Solar X-ray Monitor on the spacecraft.  The Initial Power-on and functional tests were successfully completed on December […]
