Asteroid Stories
NASA’s Lucy spacecraft will soon reach the small main belt asteroid Donaldjohanson. In this image, created by stacking images that the Lucy spacecraft took during its approach, the asteroid appears as a series of points in front of the static…
The asteroid 2024 YR4 made headlines in February with the news that it had a chance of hitting Earth on Dec. 22, 2032, as determined by an analysis from NASA’s Center for Near Earth Object Studies (CNEOS) at the agency’s…
NASA’s Lucy spacecraft is less than one month away from its next asteroid encounter. As it approaches, Lucy is keeping an eye on its target, the small main belt asteroid Donaldjohanson, using its high-resolution imager, L’LORRI, for optical navigation. At…
Work on NASA’s purpose-built asteroid hunter, Near-Earth Object (NEO) Surveyor, is progressing toward a targeted late 2027 launch. A major component of the mission, the spacecraft’s instrument enclosure journeyed back to the agency’s Jet Propulsion Laboratory in Southern California in early March…
NASA has selected eight participating scientists to join its Lucy mission to the Jupiter Trojan asteroids. These asteroids are remnants of our early solar system trapped on stable orbits associated with — but not close to — the planet Jupiter. NASA’s…
NASA’s Lucy spacecraft has its next flyby target, the small main belt asteroid Donaldjohanson, in its sights. By blinking between images captured by Lucy on Feb. 20 and 22, this animation shows the perceived motion of Donaldjohanson relative to the…
NASA has significantly lowered the risk of near-Earth asteroid 2024 YR4 as an impact threat to Earth for the foreseeable future. When first discovered, asteroid 2024 YR4 had a very small, but notable chance of impacting our planet in 2032.…
Observations made overnight on Feb. 19 – 20 of asteroid 2024 YR4 have further decreased its chance of Earth impact on Dec. 22, 2032, to 0.28%. NASA’s planetary defense teams will continue to monitor the asteroid to improve our predictions…
Now that skies are darker after a week of limited visibility around full moon, astronomers have resumed observations of asteroid 2024 YR4. Ground-based telescopes require dark skies to observe asteroids, which are often very faint. Around the time of a…
On Feb. 6, NASA’s NEO Surveyor (Near-Earth Object Surveyor) passed its critical design review, or CDR, at the agency’s Jet Propulsion Laboratory in Southern California, where the project is managed. Capping three days of presentations, a NASA Standing Review Board…
