Supercomputers simulated the orbits of 1 million satellites between Earth and the moon — and less than 10% survived

A new study simulated how theoretical satellites fared across 1 million different cislunar orbits between Earth and the moon. Researchers used a pair of powerful supercomputers to simulate the potential trajectories of 1 million satellites in a cislunar orbit between Earth and the moon. Less than 10% of these orbits remained stable throughout the simulations, but this is not as disastrous as it may sound.
