The Lucy spacecraft undergoes integration and testing at the Lockheed Martin cleanroom in Denver Colorado.

After nearly five years in space, NASA’s OSIRIS-REx spacecraft is on its way back to Earth with rocks and dust collected from asteroid Bennu.

NASA's first asteroid sample return mission begins a two-year cruise home on May 10, 2021.

Nayi Castro serves as OSIRIS-REx mission operations manager or "MOM” for short. She shares her thoughts on OSIRIS-REx leaving Bennu.

Members of NASA’s Planetary Defense Coordination Office will participate in a “tabletop exercise” to simulate an asteroid impact scenario.

Without searching for these asteroid companions before launch, Lucy runs the risk of encountering an unexpected binary pair.

New images taken during OSIRIS-REx's final flyover on April 7, 2021, reveal the aftermath of the spacecraft's historic encounter with the asteroid.

NASA’s OSIRIS-REx completed its last flyover of Bennu on April 7 and is now slowly drifting away from the asteroid;

NASA’s Lucy spacecraft has successfully completed thermal vacuum testing of both solar panels.

OSIRIS-REx will get one last close encounter with Bennu as it performs a final flyover to capture images of the asteroid’s surface.

Set to launch next year, the agency’s Psyche spacecraft will explore a metal-rich asteroid in the main asteroid belt between Mars and Jupiter.

The near-Earth object was thought to pose a slight risk of impacting Earth in 2068, but now radar observations have ruled that out.

Seen here in late 2020, the Lucy spacecraft is lifted back to its dolly as the Lockheed Martin team in Denver, Colorado, continues production.

The interplanetary interloper won’t come closer than 1.25 million miles to Earth, but it will present a valuable scientific opportunity for astronomers.

Whether you're doing it for the nerd cred or the pie, this week on #10Things, we've got all the ways you can celebrate #PiDay with NASA.

A wayward young comet-like object orbiting among the giant planets has found a temporary parking place along the way.

As astronomers discovered asteroids hiding in Jupiter’s Lagrange points, they began referring to them as “Trojan asteroids.”

The next full Moon will be early Saturday morning, Feb. 27 at 3:17 AM EST. The Moon will appear full from Thursday night through Sunday morning.

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

DART will still arrive at Didymos within a few days of the originally scheduled impact date of Sept. 30, 2022.

A months-long integration and testing phase culminated with a successful review and the start of space-environment testing for DART.

With less than a year to launch, NASA’s Lucy mission’s third and final scientific instrument has been integrated onto the spacecraft.

Before departing for Earth on May 10, OSIRIS-REx will perform a final flyby of Bennu – capturing its last images of sample collection site Nightingale.

Now just a year and a half from launch, the mission to explore a metal-rich asteroid will soon begin assembling and testing the spacecraft.
