SpaceX told the FCC in a Feb. 1 letter that it plans to launch a pair of experimental satellites on one of its Falcon 9 rockets. That launch, already approved by the FCC, is set for Saturday in California.
In 2017, SpaceX had submitted regulatory filings to launch a total of nearly 12,000 satellites to orbit by the mid-2020s. The internet communication satellites are expected to be in the smallsat-class of 100-to-500 kg (220-to-1,100 lb)-mass, which are intended to be orbiting at an altitude of approximately 1,100 kilometers (680 mi). Initial plans as of January 2015 were for the constellation to be made up of approximately 4000 cross-linked satellites, more than twice as many operational satellites as were in orbit in January 2015.
