NASA's CAPSTONE spacecraft has achieved a major milestone in space exploration, successfully capturing its first images of the Moon and testing a groundbreaking navigation technology.
The images, taken during CAPSTONE's close approach to the Moon on May 3, reveal the lunar surface near the Moon's North Pole.
CAPSTONE, the Cislunar Autonomous Positioning System Technology Operations and Navigation mission, captured an image of the Moon on May 3, 2023, during its closest approach to the Moon's North Pole. The image's center is located approximately at 25° N, 85° E on the lunar surface. In addition to this milestone, CAPSTONE successfully tested a navigation technology similar to Earth's GPS for the first time in May. This advancement enhances the potential for future space missions to navigate more efficiently on the Moon.
CAPSTONE Captures the Moon
CAPSTONE, also known as Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment, is a CubeSat with the size of a microwave oven.
It operates in a unique elliptical orbit around the Moon, a path that NASA's Gateway will utilize. The recent test involved CAPSTONE and NASA's Lunar Reconnaissance Orbiter (LRO), with both spacecraft playing crucial roles in advancing the CAPS technology.
During the May 9 experiment, CAPSTONE initiated a signal transmission to LRO intending to measure the distance and relative velocity between the two spacecraft. Subsequently, LRO transmitted the signal back to CAPSTONE, which was then converted into a measurable value.
The successful test showcased CAPSTONE's capacity to collect measurements that will be employed by the CAPS software to accurately determine the positioning of both spacecraft.
This technology has the potential to revolutionize autonomous navigation in future lunar missions, significantly improving their operational efficiency and precision.
Pivotal Mission Objective
In addition to the noteworthy CAPS test, CAPSTONE achieved a pivotal mission objective by successfully maintaining its near-rectilinear halo orbit for a duration of at least six months. This milestone signifies the fulfillment of the spacecraft's primary mission.
Nonetheless, CAPSTONE will continue its operations within this orbit, conducting further evaluations of onboard technologies during an extended mission phase, which could extend up to a year.
The image captured by CAPSTONE on May 3 showcases the extraordinary progress made by the mission. Positioned near the Moon's North Pole, the center of the image corresponds approximately to coordinates 25° N and 85° E on the lunar surface.
This visually stunning snapshot offers a glimpse into the intricate topography and features of the Moon's landscape.
The success of CAPSTONE's navigation technology and the acquisition of its first lunar images mark significant achievements for NASA and the future of space exploration.
By pushing the boundaries of our understanding and capabilities, CAPSTONE paves the way for more advanced and precise navigation systems that will revolutionize lunar missions.
