Four Space Mission Areas
(ACES) Application Control Enhancement Support
Space Enhancement
Improving the effectiveness of military forces as well as support other intelligence, civil, and commercial users.
ISR Missle Warning SATCOM Space based positioning Navigation and timing
Space Support
Deploy and sustain military intelligence systems in space
Space Control
Allow access to friendlies, deny to the enemy
Space Force application
Combat operations in space
attacks against terrestrial-based targets
What are 5 entities in the space environment
The Sun Solar Wind Solar Cycle Van Allen Radiation Belts Atmospheric Drag
Biggest effect on space environment?
The Sun
Electromagnetic radiation
electrically charged particles
Solar Wind
An oscillating force field transmitted through space in the form of a transverse wave
Solar Cycle
4 year rise to solar maximum
7 year decline to solar minimum
(Time frame in which there are more/ less solar events
Predicting sun spots
Van Allen Radiation Belts
Belt of charged particles held in place around the earth by the earths magnetic field
LEO
Low Earth Orbit
150-800 miles,
space shuttles and scientific satellites
MEO
Medium Earth Orbit
10,800 miles
12 hr period
HEO
Highly elliptical orbit
slows at apogee, speeds at perigee
long dwell over northern hemisphere
Perigee
the point in orbit closest to the earths center
Apogee
the point in orbit farthest from the earths center
