The Drive:


U.S. Space Force is considering tests of Next-Generation Overhead Persistent Infrared System early-warning satellites in Medium Earth Orbit, or MEO, as early as 2022. Placing the satellites in these non-traditional orbits would allow them to observe potential missile launch sites for longer periods of time than would be possible from Low Earth Orbit, or LEO. In addition, placing early warning and other missile defense satellites in MEO could ensure the service’s ability to detect and track threats with a smaller number of satellites than would be needed if a constellation was placed in LEO. At the same time, they could provide much-needed increased flexibility and fidelity over their forbearers that remain in geostationary orbit…
