Honeywell Helps Navigate NASA’s Mission to Study Nearby Asteroid
PHOENIX. Honeywell is working with Lockheed Martin, NASA and the University of Arizona to support the OSIRIS- REx mission to collect samples from the near- Earth asteroid Bennu, using a robotic spacecraft that launched September 8. Honeywell supplied Reaction Wheel Assemblies and Miniature Inertial Measurement Units to precisely point and stabilise the spacecraft. These technologies help make the spacecraft steadier and provide more accurate routing, making them critical to mission success.
Once launched, the OSIRIS- REx spacecraft will head to Bennu to study it in depth and to gather between 60 and 2,000 grams of materials from the asteroid’s surface. Once this is complete, OSIRIS-REx will remain in the asteroid’s orbit for about a year to collect additional data before returning to Earth in 2023. The sevenyear journey would not be possible without Honeywell’s Miniature Inertial Measurement Unit (MIMU) and its Reaction Wheel Assemblies ( RWAs) to control and orient the spacecraft. These technologies will help ensure that OSIRIS-REx is on the right trajectory as it travels to and from Bennu, and allow for more control and precision when collecting samples from the asteroid.
