In this illustration showing NEO Surveyor, NASA's next-generation near-Earth object hunter, the spacecraft floats in an infrared starfield containing stars, star clusters, gas, and dust. More than 100 asteroids can be seen as red dots, with some of them visible in a track that shows how they were captured at different times as they marched across the sky. This starfield was observed by NASA's Wide-field Infrared Survey Explorer, or WISE, during its primary all-sky survey in March 2010 before it was put into hibernation a year later. In December 2013, the space telescope was reactivated to search for more asteroids as the NEOWISE mission. NASA's NEO Surveyor will build upon the successes of NEOWISE as the first space mission built specifically to find large numbers of hazardous asteroids and comets. The space telescope will launch to a region of gravitational stability between the Earth and the Sun called the L1 Lagrange point, where the spacecraft will orbit during its five-year primary mission. From this location, the space telescope will view the solar system in infrared wavelengths &ndash light that is invisible to the human eye. Because those wavelengths are mostly blocked by Earth's atmosphere, larger ground-based observatories may miss near-Earth objects that NEO Surveyor will be able to spot from space by using its modest light-collecting aperture of nearly 20 inches (50 centimeters). NEO Surveyor's cutting-edge detectors are designed to observe two heat-sensitive infrared bands that were chosen specifically so the spacecraft can track the most challenging-to-find near-Earth objects, such as dark asteroids and comets that don't reflect much visible light. In the infrared wavelengths to which NEO Surveyor is sensitive, these objects glow as they are heated by sunlight. In addition, NEO Surveyor will be able to find asteroids that approach Earth from the direction of the Sun, as well as those that lead and trail our planet's orbit, where they are typically obscured by the glare of sunlight – objects known as Earth Trojans. The mission is tasked by NASA's Planetary Science Division within the Science Mission Directorate; program oversight is provided by the PDCO, which was established in 2016 to manage the agency's ongoing efforts in planetary defense. NASA's Planetary Missions Program Office at Marshall Space Flight Center provides program management for NEO Surveyor. The project is being developed by JPL and is led by survey director Amy Mainzer at the University of Arizona. Established aerospace and engineering companies have been contracted to build the spacecraft and its instrumentation, including Ball Aerospace , Space Dynamics Laboratory, and Teledyne. The Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder will support operations, and IPAC-Caltech in Pasadena, California, is responsible for processing survey data and producing the mission's data products.

The bus structure of the Near-Earth Object (NEO) Surveyor spacecraft underwent testing at BAE Systems Space & Mission Systems in Boulder, Colorado, in August 2025. NEO Surveyor’s bus houses the power, propulsion, avionics, and communication subsystems, which are isolated from the spacecraft’s telescope and sensitive detectors. When all components are assembled, a large sunshade will be attached to the side of the bus, blocking the Sun’s glare from entering the telescope. With an aperture of nearly 20 inches (50 centimeters), the telescope features detectors sensitive to two infrared wavelengths in which near-Earth objects re-radiate solar heat. The instrument enclosure is designed to ensure heat produced by the spacecraft and instrument during operations doesn’t interfere with its infrared observations.

This artist's concept depicts NASA's Near-Earth Object Surveyor (NEO Surveyor) in deep space. After launch, the spacecraft will travel a million miles to a region of gravitational stability – called the L1 Lagrange point – between Earth and the Sun. From there, its large sunshade will block the glare and heat of sunlight, allowing the mission to discover and track near-Earth objects as they approach Earth from the direction of the Sun, which is difficult for other observatories to do. The black-paneled angular structure in the belly of the spacecraft is the instrument enclosure that is being built at NASA's Jet Propulsion Laboratory in Southern California. The spacecraft's only instrument, its infrared telescope, will be installed inside the enclosure. Fabricated from dark composite material that allows heat to escape, the enclosure will help keep the telescope cool and prevent its own heat from obscuring observations. https://photojournal.jpl.nasa.gov/catalog/PIA26388

This picture of the European Space Agency Mars Express spacecraft by the Mars Orbiter Camera on NASA Mars Global Surveyor is from the first successful imaging of any spacecraft orbiting Mars taken by another spacecraft orbiting Mars.
This view is an enlargement of an image of NASA Mars Odyssey spacecraft taken by the Mars Orbiter Camera aboard NASA Mars Global Surveyor while the two spacecraft were about 90 kilometers 56 miles apart.

The instrument enclosure for NASA's Near-Earth Object Surveyor is prepared for environmental testing inside the historic Chamber A in the Space Environment Simulation Laboratory at the agency's Johnson Space Center in Houston in December 2024. Mounted to its articulating platform, on which it was securely positioned during assembly, the 12-foot-long (3.7-meter-long) angular structure was inspected by technicians before being placed inside the testing chamber. Figure A shows the reflective side of the instrument enclosure as it was rotated on the assembly dolly before being transferred to a testing platform. The cavernous opening to Chamber A is in the background. The instrument enclosure is designed to protect the spacecraft's infrared telescope while also removing heat from it during operations. After environmental testing was completed, the enclosure returned to NASA's Jet Propulsion Laboratory in Southern California for further work, after which it will ship to the Space Dynamics Laboratory (SDL) in Logan, Utah, and be joined to the telescope. Both the instrument enclosure and telescope were assembled at JPL. As NASA's first space-based detection mission specifically designed for planetary defense, NEO Surveyor will seek out, measure, and characterize the hardest-to-find asteroids and comets that might pose a hazard to Earth. While many near-Earth objects don't reflect much visible light, they glow brightly in infrared light due to heating by the Sun.

A mirror set to be installed inside the telescope for NASA's Near-Earth Object Surveyor (NEO Surveyor) is seen during an inspection of the mirror's surface at NASA's Jet Propulsion Laboratory in Southern California on July 17, 2024. Being built in a JPL clean room, the infrared telescope is the spacecraft's only instrument and it will be used to seek out some of the hardest-to-find near-Earth objects that may pose a hazard to our planet. The reflection of principal optical engineer Brian Monacelli can be seen in the mirror. Known as a "three-mirror anastigmat telescope," the instrument will rely on a set of curved mirrors to focus light onto its infrared detectors in such a way that minimizes optical aberrations. Before being installed, the mirrors were examined for any debris or damage. Then, JPL's team of optomechanical technicians and engineers attached the mirrors to the telescope's "optical bench" in August. Next, they will measure the telescope's performance and align the telescope's mirrors. When complete, the telescope will be housed inside an instrument enclosure – being built at JPL in a different clean room – that is fabricated from dark composite material that allows heat to escape, helping to keep the telescope cool and prevent its own heat from obscuring observations. https://photojournal.jpl.nasa.gov/catalog/PIA26386

A truck arrives at NASA's Jet Propulsion Laboratory in Southern California on June 3, 2024, to deliver the Medium Articulating Transportation System (MATS), which will be used during the construction and transportation of components for NASA's Near-Earth Object Surveyor mission. Originating at the aerospace company Beyond Gravity in Vienna, Austria, the MATS traveled via ship through the Panama Canal to Port Hueneme, California, before arriving by road at JPL. Construction has begun on NEO Surveyor's instrument enclosure in the High Bay 1 clean room at JPL's Spacecraft Assembly Facility. When the enclosure is complete later this year, it will be moved inside the MATS to NASA's Johnson Space Center in Houston for environmental testing. The MATS is a transportable clean room with its own filtration and climate control systems that keep the spacecraft and components clean, stable, and safe while being moved between facilities. NEO Surveyor's instrument enclosure contains the spacecraft's telescope, mirrors, and infrared sensors that will be used to detect, track, and characterize the most hazardous near-Earth objects. BAE Systems, Space Dynamics Laboratory, and Teledyne are among the aerospace and engineering companies contracted to build the spacecraft and its instrumentation.

Objects of this size can cause significant regional damage, or worse, should they impact the Earth. https://photojournal.jpl.nasa.gov/catalog/PIA26381

At NASA's Jet Propulsion Laboratory in Southern California, on June 7, 2024, clean room technicians use a crane to lift the lid of the Medium Articulating Transportation System (MATS) that will be used during the construction and transportation of components for NASA's Near-Earth Object Surveyor mission. Inside the MATS is the Medium Articulating Assembly Dolly (MAAD), a platform that will support the spacecraft's instrument enclosure, which is being constructed inside the High Bay 1 clean room at JPL's Spacecraft Assembly Facility. The MAAD is an articulating platform on which a spacecraft (or spacecraft components) can be mounted securely and positioned as required during assembly. It can tilt a spacecraft vertically and horizontally, rotating it 360 degrees. JPL plans to use the MAAD for future missions to reduce the number of crane lifts during assembly, test, and launch operations, known as ATLO. NEO Surveyor is the first mission to use the platform.

A major component of the mission, the instrument enclosure journeyed back to JPL in early March after completing environmental testing at NASA's Johnson Space Center in Houston. The gold-coated, circular antenna at right is part of the telescope for NASA's ASTHROS (Astrophysics Stratospheric Telescope for High Spectral Resolution Observations at Submillimeter-wavelengths), an atmospheric balloon mission; it has been in the clean room since December 2024. https://photojournal.jpl.nasa.gov/catalog/PIA26584
This stereoscopic picture of NASA Mars Odyssey spacecraft was created from two views of that spacecraft taken by the Mars Orbiter Camera on NASA Mars Global Surveyor. 3D glasses are necessary to view this image.

AS12-48-7121 (20 Nov. 1969) --- An excellent view of the unmanned Surveyor 3 spacecraft which was photographed during the Apollo 12 second extravehicular activity (EVA) on the surface of the moon. The Apollo 12 Lunar Module (LM), with astronauts Charles Conrad Jr., commander, and Alan L. Bean, lunar module pilot, aboard landed within 600 feet of Surveyor 3 in the Ocean of Storms. The television camera and several other pieces were taken from Surveyor 3 and brought back to Earth for scientific examination. Surveyor 3 landed on the side of this small crater in the Ocean of Storms on April 19, 1967. Astronaut Richard F. Gordon Jr., command module pilot, remained with the Apollo 12 Command and Service Modules (CSM) in lunar orbit while Conrad and Bean descended to explore the moon.
This image is the first view of Mars taken by the Mars Global Surveyor Orbiter Camera (MOC). It was acquired the afternoon of July 2, 1997 when the MGS spacecraft was 17.2 million kilometers (10.7 million miles) and 72 days from encounter. At this distance, the MOC's resolution is about 64 km per picture element, and the 6800 km (4200 mile) diameter planet is 105 pixels across. The observation was designed to show the Mars Pathfinder landing site at 19.4 N, 33.1 W approximately 48 hours prior to landing. The image shows the north polar cap of Mars at the top of the image, the dark feature Acidalia Planitia in the center with the brighter Chryse plain immediately beneath it, and the highland areas along the Martian equator including the canyons of the Valles Marineris (which are bright in this image owing to atmospheric dust). The dark features Terra Meridiani and Terra Sabaea can be seen at the 4 o`clock position, and the south polar hood (atmospheric fog and hazes) can be seen at the bottom of the image. Launched on November 7, 1996, Mars Global Surveyor will enter Mars orbit on Thursday, September 11 shortly after 6:00 PM PDT. After Mars Orbit Insertion, the spacecraft will use atmospheric drag to reduce the size of its orbit, achieving a circular orbit only 400 km (248 mi) above the surface in early March 1998, when mapping operations will begin. http://photojournal.jpl.nasa.gov/catalog/PIA00606

A comparison of images taken by the Hubble Space Telescope Wide Field/Planetary Camera (HST/WFPC) and the Mars Global Surveyor Orbiter Camera (MGS/MOC) shows the progress of a regional dust storm within the Valles Marineris canyons on Mars. The first HST image (left), taken in mid-May, shows no dust within the canyons. The most recent HST image (center), taken on 27 June in support of the Mars Pathfinder landing activities, shows a dust storm filling part of the canyon system and extending into the chaotic terrains at the eastern end of the canyons. The MGS/MOC image (right), acquired on July 2, shows that bright dust continues to fill the valleys. However, it does not appear to have moved significantly north of the previously observed position, suggesting that the storm remains confined to the canyon region, and does not appear to directly threaten the Pathfinder landing site (small black circle). The HST images shown here have been reduced in scale to match that of the MGS/MOC image. Although the HST is 10 times farther from Mars than MGS, its images are sharper because its resolving power is 15 times better than the MOC, and the light gathering area is almost 50 times greater. However, MGS is presently 45,000 times farther from Mars than it will be when the MOC begins its primary photography mission. At 400 km above the martian surface, the MOC wide angle camera will collect daily images at a resolution of 7.5 km/pixel, compared to HST's best of about 20 km/pixel. The narrow angle camera will observe portions of Mars at better than 1.5 m/pixel. http://photojournal.jpl.nasa.gov/catalog/PIA00607

S69-55553 (October 1969) --- Ryan Aeronautical Company artist's concept depicting a close-up view of Surveyor 3 resting in the Ocean of Storms on the lunar nearside. Two Apollo 12 astronauts are seen approaching in the background. The Apollo 12 Lunar Module (LM) is in the left background. The Earth is in the right background. The inspection of Surveyor 3, which has been resting on the moon since April 1967, is an important objective of the Apollo 12 lunar landing mission. Selected pieces of Surveyor 3 will be brought back to Earth for scientific examination. Ryan landing radar has guided both Surveyor and Apollo spacecraft to soft landings on the moon.

NASA’s Near-Earth Object (NEO) Surveyor sunshade mass simulator (the gray paneling to the right of the photo) is attached to the spacecraft’s bus structure in August 2025 at BAE Systems Space & Mission Systems in Boulder, Colorado. The angular assembly attached to the top of the bus via a system of struts is the instrument mass simulator. Mass simulators are used to replicate the weight and size of flight hardware during testing. Targeting launch in late 2027, the NEO Surveyor mission is led by Professor Amy Mainzer at the University of California, Los Angeles for NASA’s Planetary Defense Coordination Office and is being managed by the agency’s Jet Propulsion Laboratory in Southern California for the Planetary Missions Program Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama. BAE Systems Space & Mission Systems and the Space Dynamics Laboratory in Logan, Utah, and Teledyne are among the companies that were contracted to build the spacecraft and its instrumentation. The Laboratory for Atmospheric and Space Physics at the University of Colorado Boulder will support operations, and IPAC at Caltech in Pasadena, California, is responsible for producing some of the mission’s data products.
