NASA's microwave oven-sized CubeSat dubbed CAPSTONE is flying solo, blazing an unusual yet efficient deep space route to the Moon. The CubeSat is heading toward an unique orbit intended in the future for Gateway, a lunar space station built by the agency and its commercial and international partners that will support science and human exploration under Artemis.

During the next four months, CAPSTONE - short for the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment - will rack up serious mileage hurtling through deep space on its traverse from Earth to the Moon.

Assisted by the Sun's gravity, the spacecraft will reach a distance of 958,000 miles from Earth - more than three times the distance between Earth and the Moon - before being pulled back towards the Earth-Moon system.

This sinuous, gravity-driven track - called a ballistic lunar transfer, or BLT - dramatically reduces the amount of fuel the CubeSat needs to get to its target orbit. Rocket Lab's Photon upper stage released CAPSTONE onto a BLT trajectory to the Moon on July 4.

Since then, the CubeSat is using its own propulsion and the Sun's gravity to navigate to its destination. When CAPSTONE catches up to the Moon on Nov. 13, its approach will be perfectly aligned for lunar orbit insertion.

NASA invites the public to follow CAPSTONE's journey live. You can virtually ride along with the CubeSat with a simulated view of our solar system using NASA's Eyes on the Solar System interactive real-time 3D data visualization - a digital model of the solar system. This simulated view of our solar system runs on real data. The positions of the planets, moons, and spacecraft - including CAPSTONE - are shown where they are right now.

CAPSTONE is commercially owned and operated by Advanced Space in Westminster, Colorado. It represents an innovative collaboration between NASA and industry to provide rapid results and feedback to inform future exploration and science missions.

The CubeSat was designed and built by Terran Orbital Corporation. CAPSTONE includes contributions from Stellar Exploration, Inc., Space Dynamics Lab, Tethers Unlimited, Inc., and Orion Space Systems.

NASA's Small Spacecraft Technology program within the agency's Space Technology Mission Directorate (STMD) funds the demonstration mission. The program is based at NASA's Ames Research Center in California's Silicon Valley. The development of CAPSTONE's navigation technology is supported by NASA's Small Business Innovation Research and Small Business Technology Transfer (SBIR/STTR) program, also within STMD.

Can China claim ownership rights on the Moon
Maxwell AFB AL (The Conversation) Jul 10, 2022
NASA Administrator Bill Nelson recently expressed concerns over China's aims in space, and in particular, that China would, in some way, claim ownership over the Moon and stop other countries from exploring it. In an interview with a German newspaper, Nelson cautioned, "We must be very concerned that China is landing on the Moon and saying: 'It's ours now and you stay out.'" China immediately denounced the claims as a "lie". This spat between the administrator of NASA and Chinese government offici ... read more
