EarthGrid

EarthGrid is a Union of Everett NASA designed space program operated by an agency of the Department of Disaster Management. EarthGrid operates as an ever-growing asteroid, comet and meteor (ACM) defense grid which searches for, logs and tracks space debris and natural cosmic objects that pose a threat to the planet Earth. EarthGrid utilizes a series of "local space telescope and radar" (LSTR) satellites and unmanned spacecraft which search for uncharted space debris. Actively known space debris is also logged and constantly monitored on their paths and orbits and their potential level of danger to life on Earth.

EarthGrid coordinates planetary security between NASA, the Department of Disaster Management and the Department of Defense for the ability to respond to a potential threat and advert that threat accordingly. Additional coordination may be authorized with foreign space programs, most commonly the European Space Agency (ESA) and the Russian Federation.

As of 2013, some 21 LSTR satellites are in operation throughout Earth's "immediate planetary neighborhood", which consists of Earth itself, Earth's moon, Mars and Venus and a radius of 15 million miles around each planet, covering an area of some 30 million miles per the three planets. Three unmanned drone spacecraft are also used to intercept space objects of interest for study and the Everetti NASA program's Expedition class Shuttle is utilized in manned missions on occasion.
