Corona satellites were placed into near-polar orbits . 24. SDSC SHAR has infrastructure for launching satellites into low earth orbit, polar orbit and geo-stationary transfer orbit. 25. Titan IVs were also launched from the Cape Canaveral Air Force Station in Florida for non-polar orbits . 26. The polar orbit ranged between over Venus. 27. The satellite has a polar orbit of approximately 400 x 670 km altitude and 98 degree inclination. 28. "We've chosen an almost circular, polar orbit to keep the spacecraft in sunlight most of the time," 29. Prospector's polar orbit enables the spacecraft to map the entire surface of the moon every two weeks. 30. The Canadian system uses three earth stations-Edmonton, Churchill and Goose Bay, to monitor satellites in polar orbit .
