NEO Surveyor
Near-Earth Object (NEO) Surveyor is the first space telescope specifically designed to hunt asteroids and comets that may be potential hazards to Earth. As it scans the solar system, NEO Surveyor’s sensitive infrared detectors will let it track the most elusive near-Earth objects. Dark asteroids and comets don’t reflect much visible light, for example, but they will glow in the infrared spectrum as they’re heated by sunlight. The project is managed by NASA’s Jet Propulsion Laboratory (JPL) in Southern California.

An artist’s concept of NASA’s WISE (Wide-field Infrared Survey Explorer) spacecraft, which was an infrared-wavelength astronomical space telescope active from December 2009 to February 2011. In September 2013 the spacecraft was assigned a new mission as NEOWISE to help find near-Earth asteroids and comets. -
OSIRIS-REx/OSIRIS-APEX
Launched on Sept. 8, 2016, NASA’s OSIRIS-REx arrived at near-Earth asteroid Bennu in 2018, and collected a sample of dust and rocks. On Sept. 24, 2023, the spacecraft flew by Earth and dropped off the asteroid sample capsule. It didn’t land, and has a new assignment and a new name: It’s now called OSIRIS-APEX and will explore asteroid Apophis.
The sample return capsule from NASA’s OSIRIS-REx mission is seen shortly after touching down in the desert, Sunday, Sept. 24, 2023, at the Department of Defense’s Utah Test and Training Range. The sample was collected from the asteroid Bennu in October 2020 by NASA’s OSIRIS-REx spacecraft. -
Psyche
The Psyche spacecraft is on its way to a unique metal-rich asteroid with the same name, orbiting the Sun between Mars and Jupiter. By August 2029 the spacecraft will begin exploring asteroid Psyche, which scientists think may be the partial core of a planetesimal, a building block of an early planet.
This artist’s concept depicts NASA’s Psyche spacecraft with its large solar arrays fully deployed, and one of its four Hall-effect thrusters firing (visible via its blue glow) atop the spacecraft’s body.NASA/JPL-Caltech/ASU -
Lucy
NASA’s Lucy mission will explore a record-breaking number of asteroids in the solar system’s main asteroid belt, and Trojan asteroids that share an orbit around the Sun with Jupiter. Launched on Oct. 16, 2021, Lucy has already made discoveries. On Nov. 1, 2023, Lucy made its first asteroid encounter – an asteroid with a contact binary asteroid as its moonlet.

DART
NASA’s Double Asteroid Redirection Test (DART) – the world’s first planetary defense technology demonstration – successfully impacted asteroid Dimorphos on Sept. 27, 2022, in the agency’s first attempt to move an asteroid in space. Dimorphos is a moonlet to asteroid Didymos.
NASA’s DART spacecraft captured this view of asteroids Didymos, and its moonlet Dimorphos, moments before DART intentionally impacted the moonlet. -
Dawn
NASA’s Dawn spacecraft was launched in 2007 to explore asteroid Vesta, the second most massive body in the main asteroid belt. Dawn arrived at Vesta in 2011, then orbited and explored Vesta for over a year before leaving in September 2012 to explore dwarf planet Ceres.
This mosaic blends some of the best views NASA’s Dawn spacecraft took of the giant asteroid Vesta. Dawn studied Vesta from July 2011 to September 2012. -
Galileo
NASA’s Galileo mission was the first spacecraft to fly past an asteroid. It flew past asteroid Gaspra in 1991, and asteroid Ida in 1993.
This picture of asteroid Gaspra is a mosaic of two images taken by the Galileo spacecraft from a range of 3,300 miles (5,300 kilometers) some 10 minutes before closest approach on Oct. 29, 1991. -
NEAR Shoemaker
NASA’s NEAR was the first spacecraft to orbit an asteroid, and also was the first spacecraft to land on one. Launched on Feb. 17, 1996, NEAR flew by asteroid Mathilde on June 27, 1997. Then on Feb. 14, 2000, NEAR began orbiting asteroid Eros. On Feb. 12, 2001, NEAR touched down on Eros – the first time a U.S. spacecraft was the first to land on a celestial body.
This picture of Eros, the first of an asteroid taken from an orbiting spacecraft, is a mosaic of four images obtained by NASA’s NEAR spacecraft on Feb. 14, 2000, immediately after the spacecraft’s insertion into orbit. -
This image was created from a composite of two images taken seconds after NASA’s Deep Space 1 (DS1) encountered asteroid 9969 Braille. -
Stardust/Stardust NExT
NASA’s Stardust was the first spacecraft to bring samples from a comet to Earth. Launched on Feb. 7, 1999, the spacecraft flew within 155 miles (250 kilometers) of comet P/Wild 2 and collected samples of dust and volatiles from the comet’s coma. On Nov. 2, 2002, it flew by and imaged asteroid 5535 Annefrank. The spacecraft was given an extended mission known as New Exploration of Tempel 1 (NExT) that included a flyby of Comet Tempel 1.
This composite image shows the three small worlds NASA’s Stardust spacecraft encountered during its 12 year mission. Stardust performed a flyby of asteroid Annefrank on Nov. 2, 2002. Comet Wild 2 was visited by the spacecraft on Jan. 2, 2004. The comet Tempel 1 encounter occurred on Feb. 14, 2011.
Featured Asteroids
NASA has sent several robotic spacecraft to encounter asteroids up close to learn more about their composition and size.
