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.
