The path through the solar system is a rocky road. Asteroids, comets, Kuiper Belt Objects—all kinds of small bodies of rock, metal and ice are in constant motion as they orbit the Sun. But what’s the difference between them? Why do these miniature worlds fascinate space explorers so much?

Over 100 participants from 18 countries – including NASA scientists and the agency’s NEOWISE mission – took part in the international exercise.

NASA's Lucy spacecraft observed the May 15-16, 2022, total lunar eclipse from 64 million miles from the Earth.

NASA has extended the planetary science missions of eight of its spacecraft due to their scientific productivity and potential to deepen our knowledge.

Psyche was tested to ensure it can operate in the extreme conditions it will face on its trip to a metal-rich asteroid.

Asteroid 2022 EB5's discovery marks the fifth time an asteroid has been observed before hitting Earth's atmosphere.

This February’s calendar has lots of twos. There was 02-02-2022 and now 02-22-2022 – which some people are calling “Twosday.”

NASA-funded ATLAS has reached become the first survey capable of searching the entire dark sky every 24 hours for near-Earth objects.

NEA Scout will visit an asteroid estimated to be smaller than a school bus – the smallest asteroid ever to be studied by a spacecraft.

Just two weeks after launch, NASA’s DART spacecraft opened its “eye” and returned its first images from space.

Launching in August 2022 and arriving at the asteroid belt in 2026, NASA’s Psyche spacecraft will orbit a world we can barely pinpoint from Earth.

DART team members have filled the spacecraft with fuel, and are running rehearsals as they approach launch on Nov. 23, 2021.

DART is the first mission that will demonstrate asteroid deflection by changing an asteroid’s motion in space through kinetic impact.

New research found that Bennu's highly porous rocks are responsible for the surface's surprising lack of fine regolith.

NASA’s Double Asteroid Redirection Test (DART) spacecraft has arrived in California, its final stop on Earth.

NASA’s Lucy spacecraft launched Oct. 16, 2021, on a 12-year journey to Jupiter’s Trojan asteroids.

JPL's lucky peanuts are an unofficial tradition at big mission events.

Set to launch next year, NASA’s Psyche mission marks the first time the agency has set out to explore an asteroid richer in metal than rock or ice.
