1. OSIRIS-REx Mission Successfully Completes System Integration Review

    February 27, 2015 -

    This week marked the completion of an important step on the path to spacecraft assembly, test, and launch operations for the Origins, Spectral Interpretation, Resource Identification and Security – Regolith Explorer or OSIRIS-REx mission.

    The team met at the Lockheed Martin facility in Littleton, Colorado during the week of February 23, 2015 to review the plan for integrating all of the systems on the spacecraft, such as the scientific instrumentation, electrical and communication systems, and navigation systems. Successful completion of this System Integration Review means that the project can proceed with assembling and testing the spacecraft in preparations for launch in September 2016. Assembly and testing operations for the spacecraft are on track to begin next month at the Lockheed Martin facilities in Littleton.

    The OSIRIS-REx spacecraft will travel to a near-Earth asteroid, called Bennu, and bring at least a 2.1-ounce sample back to Earth for study. The mission will help scientists investigate how planets formed and how life began, as well as improve our understanding of asteroids that could impact Earth.

    NASA’s Goddard Space Flight Center in Greenbelt, Maryland, will provide overall mission management, systems engineering and safety and mission assurance for OSIRIS-REx. Dante Lauretta is the mission’s principal investigator at the University of Arizona. Lockheed Martin Space Systems in Denver will build the spacecraft. OSIRIS-REx is the third mission in NASA’s New Frontiers Program. NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages New Frontiers for the agency’s Science Mission Directorate in Washington.

    February 24, 2015 -

    Guest Blogger: Ed Beshore.  Dante has written extensively here about the science we hope to accomplish both at Bennu and when we return a sample to the Earth. He and other guest columnists like me have also discussed the design and construction of the OSIRIS-REx spacecraft and its instruments (OCAMS, OLA, OVIRS, OTES, and REXIS). […]

    February 15, 2015 -

    Guest Bloggers: Jason Hair, Dennis Reuter, and Amy Simon. Building a mission or an instrument is not for the faint of heart. While engineering teams develop plans to avoid major mishaps, sometimes even the best laid plans aren’t enough. A case in point is a series of unfortunate events that happened to the OVIRS instrument […]

  4. PI Blog: The OSIRIS-REx Heavy Launch Opportunity

    February 9, 2015 -

    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 […]
