1. Seeing Earth With All Our Eyes

2. Climbing Newton’s Mountain

3. Important Orbits Low vs. High Inclination Almost all are Prograde
Polar Orbits for global coverage
Circular Orbits strongly preferred
Constant altitude
Constant speed
Sun-Synchronous
Geosynchronous

4. About Orbits You do not need to expend fuel to stay in orbit
Satellites need attitude control fuel to correct for atmospheric drag, lunar and solar gravity, etc.
May want thrusters to help maintain orbits
Spin stabilization helps
Once below 200 km, atmospheric braking leads to re-entry

9. Sputnik I
October 4, 1957
S- (with) + put’ (path) + -nik (one who) = Sputnik
Literally, one who follows the same path

10. From Sapwood to Sputnik
An existing rocket, the SS-6, was used.
The warhead section was removed
A cluster of four more SS-6 engines was bolted around a central engine
Very Dependable
