The satellites orbit in a circular low Earth orbit at about 500 km (310 mi) altitude [347] in a high-inclination orbit for a planned six to twelve-month duration. The satellites communicate with three testing ground stations in Washington State and California for short-term experiments of less than ten minutes duration, roughly daily. [342] [348]

Ground track example from Heavens-Above.An observer in Sicily can see the International Space Station when it enters the circle at 9:26 p.m. The observer would see a bright object appear in the northwest, which would move across the sky to a point almost overhead, where it disappears from view, in the space of three minutes.
It's launch day! SpaceX is targeting 7:45 p.m. EDT to launch a Falcon 9 rocket from Launch Complex 40 at Cape Canaveral Space Force Station. If needed, seven backup launch opportunities are ...
Cape Canaveral Space Force Station and Kennedy Space Center hosted 31 orbital rocket launches, a new annual record, in 2021. Then launches leaped to 57 last year — a new record reflecting an 84% ...
True color image of the Earth from space. This image is a composite image collected over 16 days by the MODIS sensor on NASA’s Terra satellite. NASA Earth science satellite fleet as of September 2020, planned through 2023. Earth observation satellite missions developed by the ESA as of 2019.
Space probes are satellites designed for robotic space exploration outside of Earth, and space stations are in essence crewed satellites. The first artificial satellite launched into the Earth's orbit was the Soviet Union's Sputnik 1, on October 4, 1957. As of December 31, 2022, there are 6,718 operational satellites in the Earth's orbit, of ...
In June 2003, the satellite was relocated back to 101.2° W, as the satellite was incapable of providing service to Hawaii. [22] In July 2005, the satellite was relocated to 72.5° W, as the former satellite at that position (DirecTV 5) had moved to 110° W to replace DirecTV 6, which was approaching the end of its fuel life.
