cislunar

adj

1. (not-comparable)Situated between the Earth and the Moon.

   “Lt. Gen. Zhang Yulin, a former deputy commander of China’s astronaut program, wrote in The People’s Daily last year that cislunar space — the area between the Earth and moon — would “become another broad field for the expansion of human living space.””

   “The economic viability of commercial operations in cislunar space – meaning the region extending from Earth’s atmosphere to the lunar surface and beyond – might be even more remote.”
