115.1 Describe the following Space mission areas:
What is Space Force Enhancement?
Increasing the combat potential of that force and enhancing operational awareness.
-
115.1 Describe the following Space mission areas:
How many Force Enhancement functions are there?
What are they?
- 5
- -Intelligence, Surveillance, and reconnaissance
- -Missile Warning
- -Environmental Monitoring
- -Satellite Communications
- -Space-Based positioning, navigation, and timing
-
115.1 Describe the following Space mission areas:
What does Space Support Entail?
- -Space Lift operations (launching & Deploying satellite)
- -Satellite Operations (Maintaining, sustaining, and rendezvous and proximity ops).
- -Reconstitution of space forces (replenishing lost or diminished satellites.
-
115.1 Describe the following Space mission areas:
What does Space Control provide?
Freedom of action in space for friendly forces, and when directed, denies it to an adversary.
-
115.1 Describe the following Space mission areas:
What does Space Control consist of?
- -Offensive Space Control (OSC)
- -Defensive Space Control (DSC)
- -Space Situational Awareness (SSA
-
115.1 Describe the following Space mission areas:
What does Space Force Application consist of?
Attacks against terrestrial-based targets carried out by military weapon systems operating in or through space.
-
115.2 Describe the Space environment to include the following:
The Sun
The sun has the biggest effect on the space environment. Fueled by nuclear fusion, the sun fuses 600 million tons of hydrogen/sec.
-
115.2 Describe the Space environment to include the following:
What are the two by-products of the fusion process that impact space systems?
- -Electromagnetic Radiation
- -Electrically Charged Particles
-
115.2 Describe the Space environment to include the following:
What is Solar Wind?
Continuous outflow of energetic charged particles (Protons and Electrons). They exert a pressure on satellites, particularly those with large area-to mass ratios.
-
115.2 Describe the Space environment to include the following:
What is a Solar Cycle?
Solar activity is cyclic in nature following an 11yr cycle. Generally there is a 4yr rise to a solar maximum, followed by a gradual 7yr decline to solar minimum.
-
115.2 Describe the Space environment to include the following:
Explain Van Allen Radiation Belts?
The outer and inner Van Allen Radiation Belts are two concentric, donut shaped regions of stable, trapped charged particles that exist b/c the geomagnetic field near the Earth is strong and field lines are closed. These radiation belts can have serious impact on Communications satellites.
-
115.2 Describe the Space environment to include the following:
Atmospheric Drag
Produces more frictional drag on a satellite than expected and decreases its altitude while increasing its speed. Consequently, the satellite will be some distance below and ahead of its expected position when a ground radar or optical telescope attempts to locate it
-
115.2 Describe the Space environment to include the following:
What are the consequences of Atmospheric Drag?
- -Inaccurate satellite locations which can hinder rapid acquisition of SATCOM links for commanding or data transmission.
- -Costly orbit maintenance maneuvers may become necessary
- -De-orbit predictions may become unreliable
-
115.3 Identify the Following Orbits:
What is Low Earth Orbit?
A satellite that is at altitudes b/w about 150 & 800 miles above the Earth's surface. Space shuttles and some scientific satellites are typically placed here.
-
115.3 Identify the following orbits:
What is Medium Earth Orbit?
A satellite in a region above 2000Km and below 35786Km. The most common use for satellites in this region is for navigation (GPS).
-
115.3 Identify the following orbits:
What is Highly Elliptical Orbit?
Where a satellite slows down at apogee in the Northern Hemisphere and whips through perigee in the Southern Hemisphere. This provides communications in the Northern Hemisphere for nearly 75% of the satellite's orbital period.
