NEO Surveyor’s Transportation System Arrives at JPL

Workers stand nearby as a large white container with spacecraft equipment is lowered to the ground by a crane at NASA's Jet Propulsion Laboratory.

    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.

    After its primary mission ended, the WISE space telescope started it’s second act as NEOWISE. In late 2013, the spacecraft was assigned a new mission by NASA’s Planetary Science Division to help NASA identify and describe near-Earth objects (NEOs).

  • Black, top-shaped sample return capsule sits on the desert ground with flags surrounding it.


    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.


  • An illustration of asteroid Psyche in space. The asteroid appears gray with reddish patches. It has several craters, including two very large ones.


    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.

  • 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.

  • A larger asteroid on the left, and a smaller one on the right.


    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.

  • A mostly round asteroid Vesta with large craters visible.


    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.

  • A close view of asteroid Gaspra in the darkness of space.


    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.

    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.

  • A fuzzy image of asteroid Braille taken by the Deep Space 1 spacecraft.

    Deep Space 1

    Deep Space 1 (DS1) was designed to test new technologies for future deep space and interplanetary missions. As a bonus, the spacecraft also flew by asteroid 9969 Braille on July 29, 1999, at a range of about 16 miles (26 kilometers).

  • A composite image of the three worlds visited by NASA's Stardust spacecraft: an asteroid and two comets.

    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.

Featured Asteroids

NASA has sent several robotic spacecraft to encounter asteroids up close to learn more about their composition and size.
