  "account": "NASA's Starling mission, a swarm of four cubesats in low Earth orbit, is testing a groundbreaking navigation technique that could be the solution for GPS-free navigation in space. The technology, developed by NASA and industry partner EraDrive, is called FALCON (Fast Autonomous Lost-in-space Catalog-based Optical Navigation). The mission, which began three years ago, will continue until at least 2028.\n\nThe FALCON system uses data from the spacecraft's cameras and a catalog of thousands of known satellites to navigate. It identifies and matches observed satellites with its onboard database, using these reference points to determine the spacecraft's orbit. This method is particularly useful in areas where traditional GPS signals are weak or non-existent, such as beyond Earth's orbit.\n\nNASA sees potential applications for such navigation in future lunar missions, where GPS signals may not reach. The agency is planning to send astronauts to the moon's surface again by 2028 as part of its Artemis IV mission, which aims to build a permanent base on the moon. Other potential uses include lunar satellite swarms, distributed science missions, and human exploration.\n\nThe FALCON technology can also enhance space situational awareness, providing information about the environment around the spacecraft, including other satellites. This is crucial for avoiding collisions and ensuring safe operations. The mission has already achieved two major milestones. It successfully used its cameras to observe other satellites and match their information with its database, determining the spacecraft's orbit in the process. Additionally, the mission helped mission managers better understand the pathways of 200 individual objects, a task accomplished autonomously.\n\nNASA is optimistic about the potential of FALCON and plans to leverage the lessons learned for future missions to the moon and Mars, as well as for interplanetary traffic management.",
