In studying data collected from NASA’s DART (Double Asteroid Redirection Test) mission, which in 2022 sent a spacecraft to intentionally collide with the asteroid moonlet Dimorphos, the mission’s science team has discovered new information on the origins of the target binary asteroid system and why the DART spacecraft was so effective in shifting D

The Deep Space Network’s Goldstone planetary radar had a busy few days observing asteroids 2024 MK and 2011 UL21 as they safely passed Earth. Scientists at NASA’s Jet Propulsion Laboratory in Southern California recently tracked two asteroids as they flew by our planet. One turned out to have a little moon orbiting it, while the […]

The fifth Planetary Defense Interagency Tabletop Exercise focused on an asteroid impact scenario designed by NASA JPL’s Center for Near Earth Object Studies. A large asteroid impacting Earth is highly unlikely for the foreseeable future.

NASA’s near-Earth-object-hunting mission NEOWISE is nearing its conclusion. But its work will carry on with NASA’s next-generation infrared mission: NEO Surveyor. After more than 14 successful years in space, NASA’s NEOWISE (Near-Earth Object Wide-field Infrared Survey Explorer) mission will end on July 31.

NASA will host a virtual media briefing at 3:30 p.m. EDT, Thursday, June 20, to discuss a new summary of a recent tabletop exercise to simulate national and international responses to a hypothetical asteroid impact threat. The fifth biennial Planetary Defense Interagency Tabletop Exercise was held April 2 and 3, 2024, at the Johns Hopkins […]

After NASA’s historic Double Asteroid Redirection Test, a JPL-led study has shown that the shape of asteroid Dimorphos has changed and its orbit has shrunk. When NASA’s DART (Double Asteroid Redirection Test) deliberately smashed into a 560-foot-wide (170-meter-wide) asteroid on Sept. 26, 2022, it made its mark in more ways than one.

During the close approach of 2008 OS7 with Earth on Feb. 2, the agency’s Deep Space Network planetary radar gathered the first detailed images of the stadium-size asteroid. On Feb. 2, a large asteroid safely drifted past Earth at a distance of about 1.8 million miles (2.9 million kilometers, or 7 ½ times the distance […]

On January 13-14, 2014, representatives from NASA and various global research organizations convened the first meeting of the International Asteroid Warning Network (IAWN) steering committee. This group was charged with strengthening coordinated international response to a potentially hazardous near-Earth object (NEO).
