Role of Navy Space Command
Located in Dahlgren, VA.
Navy component to US Space Command
Established in 1983.
Ran 24/7 to maintain operations on the network and constant surveillance of space and provides satellite data.
Monitor all launches, maneuvers and breakups of foreign and domestic satellites.
Manages use of satellites and space support systems by the Navy and Marine Corps.
Space Force enhancement is what?
includes operations that multiply joint force effectiveness.
Provides intelligence, surveillance, and reconnaissance (ISR), missile warning, environmental monitoring, satellite comms, and space-based positioning, navigation and timing.
Space Support is what?
space lift operations (launching and deploying satellites) satellite operations, and reconstitution of space forces.
Space Control is what?
Offensive space control (OSC), defensive space control (DSC), and space situational awareness (SSA).
OSC used to deny freedom of action.
DSC used to protect space capabilities.
SSA involves characterizing space capabilities operating within the terrestrial environment.
Space Force Application is what?
- Consists of attacks against terrestrial-based targets carried out by military weapons systems operating in or through space.
What is the Sun?
Star at the center of the Solar System.
1.392m kilometer diameter. (109 earths)
accounts for about 99.8% of the solar systems mass.
3/4 of this mass is hydrogen.
Solar Wind is what?
stream of charged particles ejected from the upper atmosphere of the sun.
Mostly electrons and protons with energies usually between 10 and 100 electron volts.
Can cause some phenomena but doesn’t affect earth too much because of our magnetic field.
Solar Cycle is what?
11 year cycle of solar activity counted by observing sun spots through telescopes.
Can change climate and weather on Earth in extreme variations.
Van Allen Radiation Belts are what?
Highly charged belt of radiation surrounding the earth caused by the magnetic field of Earth blocking plasma and energy from other stars and the Sun.
Atmospheric Drag is what?
an ineffeciency requiring expense of additional energy during launch of a space object.
Low Earth Orbit
Generally defined as an orbit within the locus extending from Earth’s Surface to an altitude of 2,000km.
Medium Earth Orbit
2,000km to 35,786km. Most common use for GPS satellites, Glonass, and Galileo.
Highly Elliptical Orbit
an elliptic orbit with a low-altitude perigee and a high-altitude apogee (over 35.7k km) orbit is more eccentric than typical ellipses.
Geosynchronous Orbit
Matching rotation of Earth.
Polar Orbit
90 degrees to the equator. Passing above or nearly above both poles of a planet.
