The volume of space influenced by the Earth and/or Moon, here called cislunar space, is vast. Our usual yardstick for distance, the geosynchronous orbit radius (from the center of the Earth, 42,164 km = 1 GEO), is a small fraction of the distance between the Earth and Moon (384,402 km = 1 LD = 9.12 GEO, on average).

2023年4月1日 · Cislunar space refers to the area surrounding Earth, extending up to the Moon’s orbit, approximately 400,000 kilometers away. This region includes various orbits, such as low Earth orbit (LEO), geostationary orbit (GEO), and the lunar orbital environment.

The U.S. Space Force and U.S. Space Command must take steps today in the cislunar regime to establish the same freedom of operations it realizes in Earth orbit. These steps will include new capabilities such as space domain awareness, high bandwidth communications, and cislunar navigation technologies.

2024年12月18日 · That strategy set four objectives to support research and development for cislunar activities, expand international science and technology cooperation, extend space situational awareness (SSA)...

2024年4月27日 · Cislunar space, also known as translunar space, is the region of space that lies between Earth and the Moon. It extends from the Earth’s orbit out to the Moon’s orbit, encompassing the vast expanse of space that surrounds our planet and its natural satellite.

Cis-lunar space offers affordable near-term opportunities to help pave the way for future global human exploration of deep space, acting as a bridge between present missions and future deep space missions. While missions in cis-lunar space have value unto themselves, they can also play an important role in enabling and reducing risk for future

Cislunar is Latin for "on this side of the moon" and generally refers to the volume between Earth and the moon. Cislunar space includes LEO, Medium Earth Orbit, GEO, as well as other orbits, such as Low Lunar Orbit and NRHO, the intended orbit for the Gateway.

development of multipurpose cislunar infrastructure in advance of the interplanetary journeys that may follow. The Trump administration and subsequent U.S. leader-ship may determine that the best way to achieve human expansion into space while building a space economy is by focusing on cislunar development through a

Earth’s deep gravity well is a significant cost deterrent to expanded activities in space. For beyond LEO missions, most launch mass is propellant. The International Space Station proves that human- and machine-assembled satellites can be as big and as capable as needed and unlimited by launch vehicle size.

2023年5月30日 · Cislunar space is the next frontier in space exploration, unlocking a world of new opportunities that can drive the future for scientific advancements and economic growth for humanity. The nation's space enterprise must ensure the interoperability of its own cislunar investments, as other spacefaring nations also seek to lead in cislunar space.
