NEO Surveyor

NEO Surveyor, formerly called Near-Earth Object Camera (NEOCam), then NEO Surveillance Mission, is a planned space-based infrared telescope designed to survey the Solar System for potentially hazardous asteroids. The NEO Surveyor spacecraft will survey from the Sun–Earth L1 (inner) Lagrange point, allowing it to see objects inside Earth's orbit, and its mid-infrared detectors sensitive to thermal emission will detect asteroids independently of their reflected sunlight. The NEO Surveyor mission will be a successor to the NEOWISE mission, and the two missions have the same principal investigator, Amy Mainzer at the University of California, Los Angeles. Since first proposed in 2006, the concept repeatedly competed unsuccessfully for NASA funding against science missions unrelated to planetary defense, despite an unfunded 2005 US Congressional directive to NASA. In 2019, the Planetary Defense Coordination Office decided to fund this mission outside NASA's science budget due to its national security implications. On 11 June 2021, NASA authorized the NEO Surveyor mission to proceed to the preliminary design phase. The Jet Propulsion Laboratory will lead development of the mission. As of February 2025, NASA planned to launch NEO Surveyor on a SpaceX Falcon 9 in September 2027.

  NEO Surveyor, formerly called Near-Earth Object Camera (NEOCam), then NEO Surveillance Mission, is a planned space-based infrared telescope designed to survey the Solar System for potentially hazardous asteroids. The NEO Surveyor spacecraft will survey from the Sun–Earth L1 (inner) Lagrange point, allowing it to see objects inside Earth's orbit, and its mid-infrared detectors sensitive to thermal emission will detect asteroids independently of their reflected sunlight. The NEO Surveyor mission will be a successor to the NEOWISE mission, and the two missions have the same principal investigator, Amy Mainzer at the University of California, Los Angeles. [...] One advantage over NEOWISE is the wide field of regard. NEO Surveyor will be able to point anywhere from 45-120° in longitudinal distance from the sun and stopping at ±40° ecliptic latitude. The survey will be optimized to detect potentially hazardous objects and be performed continuously during the baseline mission (5 years). The survey will be halted each day for 2.25 hours to downlink the data. It will also be halted for calibration, station-keeping and momentum management maneuvers. NEO Surveyor will also be able to conduct targeted follow-up (TFO) to obtain more information for an object of special interest.

  The Near-Earth Object Surveyor (NEO Surveyor) is a space telescope that is designed to help advance NASA’s planetary defense efforts by using infrared bands to detect, track, and characterize Near Earth Objects (NEOs)—asteroids and comets that come within 48 million kilometers (30 million miles) of Earth’s orbit. NEO Surveyor consists of a single scientific instrument: a 50 centimeter (nearly 20 inch) diameter telescope that operates in two heat-sensing infrared wavelengths. It will be capable of detecting both bright and dark asteroids, which are the most difficult type to find. Scheduled to launch in 2026, the mission will help fulfill a Congressional mandate to catalog more than 90 percent of all NEOs larger than 140 meters (460 feet) across.

• NEO Surveyor - NSS

  The Near Earth Object Surveyor, also called the NEO Surveillance Mission (NEOSM), is a space-based, infrared telescope specifically designed to locate and characterize asteroids that could pose a danger to Earth. The spacecraft is currently in development and is expected to launch in 2027. Its camera will see in the infrared (IR) spectrum, allowing it to detect dark asteroids, which, warmed by the Sun, will be brighter in the infrared spectrum than the background of space. NEO Surveyor will be placed in orbit between the Earth and the Sun (a halo orbit around Sun-Earth Lagrange Point 1), so it can see asteroids that would approach the Earth during daylight, from close to the Sun. NEO Surveyor is expected to perform better than telescopes on Earth, seeing both darker asteroids and

  Neocam_wide Neos_logo Overview: NEO Surveyor is a new mission that is designed to discover and characterize most of the potentially hazardous asteroids that are near the Earth. NEO Surveyor consists of an infrared telescope and wide-field camera operating at thermal infrared wavelengths. NEO Surveyor's primary science objectives are to assess the present-day risk of near-Earth object (NEO) impact, study the origin and ultimate fate of our solar system's asteroids, and find the most suitable NEO targets for future exploration by robots and humans. The NEO Surveyor mission has been funded for development by NASA, with a launch date of no later than June 2028. Links : Near-Earth Object Surveyor Homepage : NASA NEO Surveyor website
