OSIRIS-REx: Sample Return On September 24th, 2023, NASA’s OSIRIS-REx mission reached a thrilling conclusion with the return of a sample from the asteroid Bennu back to Earth. It represents NASA’s first ever asteroid sample return, and it promises to reveal clues about the origin of our solar system, the origin of our planet, and potentially the origin of life itself. The mission has been characterized by remarkable successes at every stage over its 7 year journey in space, which is a testament to the team behind it – led by Principal Investigator and University of Arizona Regents Professor at the Lunar and Planetary Lab, Dante Lauretta. But there’s one last stage of the mission which all others depend upon: the safe delivery of the sample capsule through Earth’s atmosphere, and the gentle deployment of a parachute to ease its landing in the Utah desert. SPACEWATCH SPACEWATCH is a NASA-funded program at the University of Arizona’s Lunar and Planetary Lab that was founded in 1980 to keep track of hazardous asteroids and comets in our solar system that might pose an impact threat to Earth. The program, led by Principal Investigator Melissa Brucker, makes observations 24+ nights a month from Kitt Peak National Observatory in Arizona. Their most recent headline-grabbing collaboration was with the NASA DART mission, which smacked a small spacecraft into an asteroid to see how well it could deflect the rock from its orbital trajectory, as a test for planetary defense.
