18th Space Control Squadron
The 18th Space Defense Squadron (18 SDS) is a United States Space Force Space Domain Awareness unit located at Vandenberg Space Force Base, California. The 18th SDS is tasked with executing command and control of the space surveillance network (SSN), maintaining the resident space object (RSO) database and managing United States Space Command's space situational awareness (SSA) sharing program to United States, foreign government, commercial, and academic entities. The squadron also conducts advanced analysis, sensor optimization, conjunction assessment, human spaceflight support, reentry/break-up assessment, and launch analysis. Mission The mission of the 18th SDS is to provide and advance a continuous, comprehensive, and combat-relevant understanding of the space situation. The squadron processes SSN data to monitor all activity to, in, and from space, and maintains custody of all resident space objects. Primary mission functions include launch detection and tracking, co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Domain Awareness
Space domain awareness is the study and monitoring of satellites orbiting the Earth. It involves the detection, tracking, cataloging and identification of artificial objects, i.e. active/inactive satellites, spent rocket bodies, or Space debris, fragmentation debris. Aims Space domain awareness accomplishes the following: * Predicting when and where a decaying space object will Atmospheric entry, re-enter the Earth's atmosphere; * Preventing a returning space object, which to radar looks like a missile, from triggering a false alarm in missile-attack warning sensors; * Charting the present position of space objects and plot their anticipated orbital paths; * Detecting new human-made objects in space; * Producing a running catalogue of human-made space objects; * Determining which country owns a re-entering space object; * Informing countries whether or not objects may interfere with satellites and International Space Station orbits; * Providing data for future Anti-satellite wea ...

Space Debris
Space debris (also known as space junk, space pollution, space waste, space trash, space garbage, or cosmic debris) are defunct human-made objects in spaceprincipally in Earth orbitwhich no longer serve a useful function. These include derelict spacecraft (nonfunctional spacecraft and abandoned launch vehicle stages), mission-related debris, and particularly numerous in-Earth orbit, fragmentation debris from the breakup of derelict rocket bodies and spacecraft. In addition to derelict human-made objects left in orbit, space debris includes fragments from disintegration, erosion, or collisions; solidified liquids expelled from spacecraft; unburned particles from solid rocket motors; and even paint flecks. Space debris represents a risk to spacecraft. Space debris is typically a negative externality. It creates an external cost on others from the initial action to launch or use a spacecraft in near-Earth orbit, a cost that is typically not taken into account nor fully accoun ...

Cheyenne Mountain Space Force Station
Cheyenne Mountain Space Force Station (CMSFS) is located in Cheyenne Mountain on the Front Range of the Rocky Mountains in unincorporated El Paso County, Colorado, next to Colorado Springs, The Cheyenne Mountain Complex, an underground facility within Cheyenne Mountain SFS, was first built for the North American Aerospace Defense Command (NORAD) Combat Operations Center, though NORAD moved day-to-day operations to its headquarters on Peterson AFB in 2006. However, day-to-day operations were moved back in 2011 after a major overhaul and renovation. The location now supports U.S. Space Command's Missile Warning Center, other strategic warning and survivable capabilities, and provides a ready alternative operating location for NORAD's command center. Background Until 2006, Cheyenne Mountain was the center for the United States Space Command and NORAD which monitored the air space of Canada and the United States through a worldwide system for early warnings of missiles, spac ...
