Images from the November 2023 flyby of asteroid Dinkinesh by NASA’s Lucy spacecraft show a trough on Dinkinesh where a large piece — about a quarter of the asteroid — suddenly shifted, a ridge, and a separate contact binary satellite (now known as Selam). Scientists say this complicated structure shows that Dinkinesh and Selam have […]

The spacecraft already is beyond the distance of Mars and is using ion propulsion to accelerate toward a metal-rich asteroid, where it will orbit and collect science data. NASA’s Psyche spacecraft passed its six-month checkup with a clean bill of health, and there’s no holding back now.

Like boulders, rocks, and pebbles scattered across a landscape, asteroids come in a wide range of sizes. Cataloging asteroids in space is tricky because they are faint and they don’t stop to be photographed as they zip along their orbits around the Sun. Astronomers recently used a trove of archived images taken by NASA’s Hubble […]

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 […]

The Scout impact assessment system calculated where and when the asteroid 2024 BX1 would impact Earth’s atmosphere, providing a useful demonstration of planetary defense capability. A small asteroid about 3 feet (1 meter) in size disintegrated harmlessly over Germany on Sunday, Jan. 21, at 1:32 a.m. local time (CET).
