Preliminary results indicate that NASA’s OSIRIS-REx spacecraft successfully executed a 0.4-mile (620-m) flyover of site Nightingale yesterday as part of the mission’s Reconnaissance B phase activities.

Spitzer, designed to reveal the far, cold and dusty side of the universe, made discoveries its designers never even imagined, including a previously unseen ring of Saturn.

NASA’s Lucy mission team is seeing double after discovering that Eurybates, the asteroid the spacecraft has targeted for flyby in 2027, has a small moon. This bonus science opportunity was discovered by the Hubble Space Telescope.

To celebrate the 10th anniversary of the spacecraft's launch, the mission team has gathered their top 10 images and graphics based on WISE and NEOWISE data.

The spacecraft discovered that asteroid Bennu could be active, consistently discharging particles into space.

NASA’s OSIRIS-REx mission is just days away from selecting the site where the spacecraft will snag a sample from asteroid Bennu.

NASA’s Lucy mission successfully completed its Critical Design Review on Oct. 18.

The next full Moon will be on Sunday afternoon, October 13, 2019, The Moon will appear full for about three days centered on this time, from Saturday morning to Tuesday morning.

Two relatively medium-sized asteroids will fly safely past Earth overnight Sept. 13-14 (Eastern U.S. time).

After months grappling with the rugged reality of asteroid Bennu’s surface, the team leading NASA’s first asteroid sample return mission has selected four potential sites.

Twenty-five years ago, humanity first witnessed a collision between a comet and a planet.

NASA has selected eight new research teams to collaborate on research into the intersection of space science and human space exploration as part of the Solar System Exploration Research Virtual Institute (SSERVI).

NASA has selected three finalists among a dozen concepts for future small satellites.

After nearly 16 years of exploring the cosmos in infrared light, NASA's Spitzer Space Telescope will be switched off permanently on Jan. 30, 2020.

Scientists have solved the mystery of how Ceres’ gigantic volcanic dome, Ahuna Mons, was formed.

DART – NASA’s first mission to demonstrate a planetary defense technique – will get one chance to hit its target, the small moonlet in the binary asteroid system Didymos.

On April 13, 2029, asteroid Apophis will cruise harmlessly by Earth at distance of about 19,000 miles (31,000 kilometers). Scientists are already planning observations and science opportunities for the event.

Next week at the 2019 Planetary Defense Conference, NASA’s PDCO and other U.S. agencies and space science institutions, along with international partners, will participate in a “tabletop exercise” that will play out a realistic—but fictional—scenario for an asteroid on an impact trajectory with Earth.

Five years of data have significantly advanced scientists' knowledge of asteroids and comets in our solar system, as well as the stars and galaxies beyond.

The Space Foundation presented NASA's Dawn mission with the 2019 John L. "Jack" Swigert, Jr., Award for Space Exploration.

A small asteroid has been caught in the process of spinning so fast it’s throwing off material.

Bennu has revealed itself to be more rugged than expected, challenging the mission team to alter its flight and sample collection plans, due to the rough terrain.

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.

Just as dust gathers in corners and along bookshelves in our homes, dust piles up in space too. But when the dust settles in the solar system, it’s often in rings.

Using insights from the Dawn mission, scientists pursue clues to Ceres’ secrets by simulating its conditions on Earth.
