A small satellite is preparing to pave the way for something much greater: a fully grown lunar space station. NASA’s CAPSTONE satellite is scheduled to launch on Monday and then travel to a unique lunar orbit on the Pathfinder mission Artemis programwhich seeks to return humans to the moon later this decade.
capstone He rides aboard Rocket Lab’s Electron rocket, which will take off from the private company’s Launch Complex 1 in Mahia, New Zealand. Rocket Lab made headlines in May using a helicopter to catch a falling booster missile. CAPSTONE is scheduled to launch at 6 AM ET on June 27 with live coverage starting an hour earlier. You can watch the event in the agency website or ApplicationOr, you can watch it on the live stream below.
About a week after the CAPSTONE mission, the probe’s flight will be available through NASA Eyes on the solar system Interactive 3D visualization of data in real time.
The Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) mission will send a microwave-sized satellite into near corona orbit (NRHO) around the moon. The satellite will be the first to sail its way around this unique lunar orbit, testing it for the planned date Moon Gatea small space station intended to allow a permanent human presence on the moon.
NRHO is special in that it is where the gravitational force of the Moon and Earth interact. This orbit would theoretically keep the spacecraft in a “beautiful gravitational spot” in a near-stable orbit around the Moon, according to to NASA. Therefore NRHO is ideal because it will require less fuel than conventional orbits and will allow the proposed lunar space station to maintain a stable line of communication with Earth. But before NASA builds its gateway into this highly elliptical orbit, the space agency will use CAPSTONE — which is owned and operated by Colorado-based Advanced Space — to test its orbital models.
Six days after launch from Earth, the upper stage of the Electron rocket will launch the CAPSTONE satellite on its journey to the Moon. The 55-pound (25-kilogram) cube vehicle will perform the rest of the four-month solo journey. Once on the moon, CAPSTONE will test the orbital dynamics of its orbit for about six months. The satellite will also be used to test spacecraft-to-spacecraft navigation technology and unidirectional range capabilities that could eventually reduce the need for future spacecraft to communicate with mission controllers on Earth and wait for signals from other spacecraft to relay.
NASA is systematically putting together the pieces for the agency’s planned return to the Moon. The The fourth and final rehearsal for the space agency’s Space Launch System (SLS) went wellpaving the way for a possible launch in late August.
