The aim is to get the most out of the onboard experiment, a collaboration with industry partner EraDrive called FALCON (short for \"Fast Autonomous Lost-in-space Catalog-based Optical Navigation\").<\/p><iframe src=\"https:\/\/content.jwplatform.com\/players\/ulIy8KlP.html\" id=\"ulIy8KlP\" title=\"SpaceX\u00a0launches\u00a0GPS satellite\u00a0for U.S. Space Force\" width=\"1920\" height=\"1078\" frameborder=\"0\" scrolling=\"auto\" allowfullscreen><\/iframe><p>\"As NASA prepares for more missions beyond Earth's orbit, technologies like FALCON can support lunar satellite swarms, distributed science missions and human exploration,\" NASA officials said in Monday's statement.<\/p><p>While NASA's applications are civilian, alternative GPS solutions are also being investigated by the U.S. Department of Defense (DoD) out of concern that the limited number of GPS satellites could be vulnerable to adversaries. Earlier this year, for example, <a href=\"https:\/\/www.space.com\/us-space-force-history-mission-capabilities\"><u>Space Force<\/u><\/a> entities SpaceWERX and Space Systems Command jointly <a href=\"https:\/\/afwerxchallenge.com\/spacewerx26\/altpnt\/overview\"><u>launched an initiative<\/u><\/a> aiming for new ideas for \"positioning, navigation and timing\" (PNT) capabilities in space.<\/p><p>The aim of FALCON, however, is to deal with sheer distance. While satellites in Earth orbit have ample access to purpose-built navigational markers such as GPS, that access rapidly thins out as missions go farther afield. And this isn't just an abstract concern; NASA aims to send astronauts to the surface of <a href=\"https:\/\/www.space.com\/55-earths-moon-formation-composition-and-orbit.html\"><u>the moon<\/u><\/a> again as soon as 2028 on the Artemis IV mission, as part of a larger effort to build a <a href=\"https:\/\/www.space.com\/astronomy\/moon\/artemis-moon-base-will-cover-hundreds-of-square-miles-with-hopping-drones-and-new-lunar-rovers-nasa-says\"><u>moon base<\/u><\/a>. <\/p><p>Industry and the military are also very interested in the moon and the area around it, known as cislunar space \u2014 and how best to navigate in the new environment. The moon's orbit also introduces complications to navigation; in 2025, for example, Canada's Outer Space Institute <a href=\"https:\/\/outerspaceinstitute.ca\/osisite\/wp-content\/uploads\/Workshop-Report-on-cislunar-security-FINAL-2FEB2025.pdf\" ><u>reported<\/u><\/a> that \"mass concentrations,\" or <a href=\"https:\/\/www.space.com\/21364-moon-gravity-mascons-mystery.html\"><u>mascons<\/u><\/a>, pull down on orbiting satellites and may affect their pathway, in some cases even inducing crashes into the lunar surface.<\/p><p>But before testing at the moon, NASA wants to learn more closer to home. It partnered with EraDrive, an autonomous spacecraft navigation company that originated with a group at Stanford University, which provided flight software and algorithms for FALCON. The experiment uses data from Starling's cameras, as well as a catalog on the spacecraft that charts thousands of known <a href=\"https:\/\/www.space.com\/24839-satellites.html\"><u>satellites<\/u><\/a> and space objects around it. <\/p><p>The mission not only is trying out \"GPS-independent navigation\" but is also showcasing space situational awareness, or SSA \u2014 that is, the ability to understand the environment around the spacecraft (including other satellites). Some other spacecraft, like SpaceX's <a href=\"https:\/\/www.space.com\/spacex-starlink-satellites.html\"><u>Starlink<\/u><\/a> broadband satellites, use SSA to automatically <a href=\"https:\/\/www.space.com\/space-exploration\/satellites\/every-spacex-starlink-satellite-has-to-dodge-a-collision-almost-weekly-and-experts-fear-the-worst\"><u>dodge threats of space debris<\/u><\/a> in LEO.<\/p><p>Starling's team is hoping to bring even more capabilities for navigation and SSA. \"The results from FALCON can have far-reaching implications for on-orbit space-traffic monitoring, <a href=\"https:\/\/www.space.com\/space-exploration\/satellites\/every-spacex-starlink-satellite-has-to-dodge-a-collision-almost-weekly-and-experts-fear-the-worst\"><u>collision avoidance<\/u><\/a> and alternative navigation,\" Roger Hunter, program manager for NASA's small spacecraft and distributed systems program, said in the statement. <\/p><figure class=\"van-image-figure  inline-layout\" data-bordeaux-image-check ><div class='image-full-width-wrapper'><div class='image-widthsetter' style=\"max-width:1992px;\"><p class=\"vanilla-image-block\" style=\"padding-top:56.22%;\"><img id=\"iMpp9op7zEN4JccYsQDDCd\" name=\"1774462170.jpg\" alt=\"artist's illustration of a base on the moon.\" src=\"https:\/\/cdn.mos.cms.futurecdn.net\/iMpp9op7zEN4JccYsQDDCd.jpg\" mos=\"\" align=\"middle\" fullscreen=\"\" width=\"1992\" height=\"1120\" attribution=\"\" endorsement=\"\" class=\"inline\"><\/p><\/div><\/div><figcaption itemprop=\"caption description\" class=\" inline-layout\"><span class=\"caption-text\">NASA plans a to build a permanent base on the moon over the next decade or so, via a step-by-step approach. <\/span><span class=\"credit\" itemprop=\"copyrightHolder\">(Image credit: NASA)<\/span><\/figcaption><\/figure><p>FALCON notched two major milestones in its first three years. For PNT, the spacecraft used its cameras to observe other satellites and objects \u2014 and to match their information with the onboard database, which includes roughly 20,000 objects from publicly available DoD records. \"FALCON then used the observed and verified objects as reference points to determine Starling's orbit,\" NASA stated. <\/p><p>FALCON's in-orbit observations also helped mission managers better understand the pathways of 200 individual objects, beyond the orbital estimates in the DoD catalog. The estimating work was performed over just three days and autonomously, meaning ground operators did not participate.<\/p><p>\"The self-orbit determination capability made possible through FALCON is a first for spacecraft using optical cameras, to navigate by their relative position to other objects in space,\" NASA stated. \"Separately, the catalog-update experiments produced better object position predictions onboard Starling than those provided by ground stations.\"<\/p><p>Starling's four spacecraft operate at an altitude of about 350 miles (565 km), which is about 6 miles (10 km) higher than originally planned. That's because <a href=\"https:\/\/www.space.com\/18853-spacex.html\"><u>SpaceX<\/u><\/a> advised mission managers that Starling's mission plan put it at risk of coming close to Starlink satellites already operating in an orbital shell at 340 miles (555 km), <a href=\"https:\/\/spacenews.com\/nasa-spacex-to-test-satellite-crash-prevention-strategies\/\" ><u>according to Space News<\/u><\/a>. By comparison, the <a href=\"https:\/\/www.space.com\/space-exploration\/missions\/international-space-station\"><u>International Space Station<\/u><\/a> typically orbits slightly lower than Starling or Starlink, at 250 miles (400 km).<\/p><p>All of which is to say that the Starling mission demonstrates operations in crowded conditions.
