21. Cordelia's orbit is within Uranus'synchronous orbit radius, and is therefore slowly decaying due to tidal deceleration. 22. EnMAP records data via a sun-synchronous orbit at a height of 643 km above the Earth. 23. The satellite was in a sun-synchronous orbit with an ascending node time of about 9 AM. 24. DMSP satellites circle the Earth at an altitude of about 500 miles in a near-polar, sun-synchronous orbit . 25. The satellite was placed into a sun-synchronous orbit 824 km ( 512 miles ) above the Earth. 26. Diagram showing the orientation of a Sun-synchronous orbit ( green ) in four points of the year. 27. The humans and others are on a satellite in synchronous orbit above the explorers on the ground. 28. This indicated a synchronous orbit , which strongly suggested that the bulge effect was real and not spurious. 29. Galatea's orbit lies below Neptune's synchronous orbit radius, so it is slowly spiralling inward due to tidal stretching. 30. Members of the A-train fly very close together in sun-synchronous orbit , to make nearly simultaneous measurements of Earth.
