I realise this is an Earth Observation part of the forum, but started a comms satellites topic anyway

Hey, that was very, very cool indeed; thanks, Phil!
Man, they must've been sweating bullets throughout that antenna deployment; amazingly complex operation. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Talking about communications satellites ( or spy satellite ):
What was the highest orbit used for satellites to observe Earth ( we do not count the geo-stationary satellites at 36000 km ). I guess the Apogee of Russian Molniya orbits lay around 40000 Km ??? |

Well, if you count observing Earth just because it happens to be in its field of view, then consider the old Vela satellites at 100,000 to 110,000 km.
Talking about comsats, a proposed system for what eventually became Milstar had satellites in polar orbit also at about 110,000 km for higher survivability in a nuclear war. Milstar was expensive enough, the earlier system would have been freaking expensive. |
