Near-Earth Object Surveillance Mission Near-Earth Object Camera NEOCam: Mission type: Asteroid impact avoidance, astronomy: Operator: NASA / JPL: Website: https://neos.arizona.edu/ Mission duration: 12 years (planned) [1] Spacecraft properties; Manufacturer: Jet Propulsion Laboratory [1] Launch mass: 1,300 kg (2,900 lb) [1] Start of mission ...
Near-Earth comets (NECs) are objects in a near-Earth orbit with a tail or coma made up of dust, gas or ionized particles emitted by a solid nucleus. Comet nuclei are typically less dense than asteroids but they pass Earth at higher relative speeds, thus the impact energy of a comet nucleus is slightly larger than that of a similar-sized ...
The Center for Near-Earth Object Studies (CNEOS) is the Jet Propulsion Laboratory's (JPL's) facility for computing asteroid and comet orbits and their probability of Earth impact. [1] [2] CNEOS is located at, and operated by, Caltech in Pasadena, California. CNEOS computes high-precision orbits for Near-Earth Objects (NEOs).
Sentry is an automated impact prediction system started in 2002 and operated by the Center for Near Earth Object Studies (CNEOS) at NASA's Jet Propulsion Laboratory. It continually monitors the most up-to-date asteroid catalog for possibilities of future impact with Earth over the next 100+ years. [1]
In 2005, the U.S. Congress passed the NASA Authorization Act, which, in part, tasked NASA with finding and cataloguing at least 90% of all near-Earth objects that are 140 meters or larger by 2020. [ 6 ] [ 7 ] However, that goal was clearly not being met by NASA's Near Earth Object Observations Program, which a 2014 report by the NASA Office of ...
In 2013, NASA reactivated the WISE telescope to search for near-Earth objects (NEO), such as comets and asteroids, that could collide with Earth. [12] [13] The reactivation mission was called Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE). [13] As of August 2023, NEOWISE was 40% through the 20th coverage of the full sky ...
The LINEAR project began operating a near-Earth object discovery facility in 1996 using a 1.0 m (39 in) aperture telescope designed for the Air Force Space Command's Ground-based Electro-Optical Deep Space Surveillance (GEODSS). The wide-field Air Force telescopes were designed for optical observation of Earth-orbiting spacecraft.
2024 MK is a near-Earth object with a diameter around 150 meters that flew past Earth on June 29, 2024. [1] It was discovered by ATLAS South Africa, Sutherland on 16 June 2024. [2] This asteroid travels in both the main-belt and in the near-Earth region. It passed Earth on 29 June 2024 at a distance of 184,000 miles (295,000 kilometers).
