|Course Prerequisites and Class Restriction
|In this course, space regions where spacecraft move are studied using satellite observations, simple available models and
theory. In addition to Sun, solar activity (solar flares, CMEs, sunspots etc.), solar wind, interplanetary magnetic field (IMF),
electromagnetic radiations, these include Earth’s magnetic field, magnetosphere, magnetotail, magnetopause, bow shock.
Each region’s formation and characteristics are examined. Magnetic reconnection, magnetic storms, magnetospheric
substorms, aurorae, radiation belts, south Atlantic anomaly (SAO) are studied. Effects of the space environment on spacecraft
and ground systems were examined, such as spacecraft charging, oxygen erosion, atmospheric drag, SEO events,
geomagnetically induced currents, effects on communication and navigation are studied. Simple models for the environment
are introduced and spacecraft observations in different regions are analyzed.
