Over 100 participants from 18 countries – including NASA scientists and the agency’s NEOWISE mission – took part in the international exercise.
PASADENA, Calif. (NASA PR) — Watching the skies for large asteroids that could pose a hazard to the Earth is a global endeavor. So, to test their operational readiness, the international planetary defense community will sometimes use a real asteroid’s close approach as a mock encounter with a “new” potentially hazardous asteroid. The lessons learned could limit, or even prevent, global devastation should the scenario play out for real in the future.

PASADENA, Calif. (NASA PR) — NASA has approved the Near-Earth Object Surveyor space telescope (NEO Surveyor) to move to the next phase of mission development after a successful mission review, authorizing the mission to move forward into Preliminary Design (known as Key Decision Point-B). The infrared space telescope is designed to help advance NASA’s planetary defense efforts by expediting our ability to discover and characterize most of the potentially hazardous asteroids and comets that come within 30 million miles of Earth’s orbit, collectively known as near-earth objects, or NEOs.
PASADENA, Calif. (NASA PR) — A comet visiting from the most distant parts of our solar system is putting on a spectacular nighttime display. Named Comet C/2020 F3 NEOWISE, the comet made its once-in-our-lifetimes close approach to the Sun on July 3, 2020, and will cross outside Earth’s orbit on its way back to the outer parts of the solar system by mid-August.
