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 Near Earth Network (NEN, formerly GN or Ground Network) provides orbital communications support for near-Earth orbiting customer platforms via various ground stations, operated by NASA and other space agencies. It uses a number of different dishes scattered around the globe.
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.

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 ...

In low-earth orbit, objects can collide at around 23,000 miles an hour, enough for even the tiniest debris to crack the windows on the International Space Station. Nearly 30,000 objects are ...
