With this new stamp, the U.S. Postal Service celebrates NASA’s seven-year OSIRIS-REx mission to study and map the asteroid Bennu and deliver a sample of the surface to Earth, landing in the Utah desert on September 24, 2023. The sample will help scientists learn how the solar system formed. OSIRIS-REx–a collaboration between NASA, the University of Arizona, and Lockheed Martin–exemplifies American ingenuity, perseverance, and teamwork.
