Let's see - a foreign object positioned above the United States in a low orbit.... pretty sure that will get shot down.
- bdunbar 15y agoA few kilometers up is not orbit. And .. foreign satellites go overhead all the time. That's how orbit _works_.
- prophetjohn 15y agoIt's also trivial to place an object into orbit at a speed such that it stays in the same place relative to Earth. So a given satellite in orbit does not necessarily need to pass over the United States. This is why you have to get on your roof and point the dish at some magical place in the sky. You're pointing it at the satellite
- DiabloD3 15y agoThe term you are looking for is "geosynchronous".
- bdunbar 15y agoGiven the cost of sending missions to GEO, the time involved to put anything into orbit, how tedious and pesky rockets are, you have a funny definition of 'trivial'.
- prophetjohn 15y agoI'm referring to the difference in difficulty among putting a satellite into non-geosynchronous orbit and putting a satellite into geosynchronous orbit.
- DanBC 15y agoGeosynchronous orbit is not "trivial" - it's a long way from Earth. A geostationary orbit is about 35,700 km above Earth. That's about (correct me if I'm wrong) about 500 milli-seconds there and back.
