MIT physicists captured the first images of individual atoms freely interacting in space. The pictures reveal correlations among the “free-range” particles that until now were predicted but never directly observed.

Satellite constellation has been applied in communication, reconnaissance, navigation, and other space missions, such as GPS, Glonass, Beidou, Starlink, etc. With the rapid development of Low Earth Orbit (LEO) constellations, mega constellation will inevitably become an important means of Earth observation and a key point in the development of future satellite technology. The configuration optimization design of LEO observation mega constellation in complex space environment is a nonlinear problem that is difficult to solve analytically. During the development, constellation design principles have shifted from the uniform coverage requirement to application requirements. However, previous method cannot provide solutions to constellation configuration optimal design based on high-precision orbital propagation.
