- Mr. McCann is describing space-based weapons platforms in geosynchronis orbit.
- Notice the words "stationary orbits." For an object to be in orbit, its
- centripetal acceleration due to its motion about the earth must equal the
- acceleration to due gravity. In other words, its centrifugal force must equal
- its weight. Each altitude has one and only one orbital speed at which this
- equality holds, and it can be determined by Newton's laws of gravitation and
- motion. A hovering craft is not in orbit.
-
- There is an altitude at which the time an object takes to complete the orbit
- is equal to exactly one day. If this orbit is over the equator, the satellite
- will appear from the earth to hover over a point on the equator. An object
- in such an orbit (22,000 miles high for Earth) requires no power to maintain
- it -- a rock will do it as easily as a manned spaceship.
-
- It is obvious to me that Mr. McCann is concerned about Soviet geostationary
- satellites and is calling for development of an American Anti-Satellite weapons
- system (ASAT) to deal with it. No electrogravitic cosmospheres is implied in
- the above paragraph -- just geostationary satellites.
-
- I'm sorry if you already understand orbital mechanics -- but objects "floating
- in stationary orbits" require no power source and have no need of "electro-
- gravitic devices."
-
- OK. I have a question for you. If Columbia and the three other Shuttles were
- destroyed on STS-1,2,3,4, where did all of the Shuttles come from? There
- have been 52 Shuttle launches so far, and orbiters cost $1.5 billion a piece.
- Do you think NASA can hide THAT kind of money? How could it hide the produc-
- tion?
