ULA is planning a live stream of launch coverage via its website.<\/p>\n<p>The first launch attempt was scrubbed on April 9 due to weather concerns, and range scheduling conflicts forced ULA to wait until now for its next opportunity. Forecasters say there\u2019s a 70% chance of acceptable weather for today\u2019s attempt. Tuesday has been reserved for a third try, just in case clouds, storms or technical issues force another postponement.<\/p>\n<p>Amazon said the mission \u2014 known as Kuiper-1 or KA-1 (for Kuiper Atlas 1) \u2014 will put 27 Kuiper satellites into orbit at an altitude of 280 miles (450 kilometers).<\/p>\n<p>ULA launched two prototype Kuiper satellites into orbit for testing in October 2023, but KA-1 will mark Amazon\u2019s first full-scale launch of a batch of operational satellites designed to bring high-speed internet access to millions of people around the world.<\/p>\n<p>\u201cWe\u2019ve designed some of the most advanced communications satellites ever built, and every launch is an opportunity to add more capacity and coverage to our network,\u201d Rajeev Badyal, vice president of Project Kuiper, said in a pre-launch blog posting. \u201cWe\u2019ve done extensive testing on the ground to prepare for this first mission, but there are some things you can only learn in flight, and this will be the first time we\u2019ve flown our final satellite design and the first time we\u2019ve deployed so many satellites at once.\u201d<\/p>\n<p>Badyal said \u201cthis is just the start of our journey, and we have all the pieces in place to learn and adapt as we prepare to launch again and again over the coming years.\u201d<\/p>\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-4-3 wp-has-aspect-ratio\">\n<iframe loading=\"lazy\" title=\"Rocket Launch: Atlas V Kuiper 1\" width=\"800\" height=\"450\" src=\"https:\/\/www.youtube.com\/embed\/_nwyv0fPgmc?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen=\"\"><\/iframe><br \/>\n<\/figure>\n<p>According to Amazon, the Kuiper satellite design has gone through significant upgrades since the prototypes were launched in 2023. Amazon\u2019s primary manufacturing facility is in Kirkland, Wash., with some of the components produced at Project Kuiper\u2019s headquarters in nearby Redmond.<\/p>\n<p>\u201cWe have improved the performance of every system and sub-system on board, including phased array antennas, processors, solar arrays,&nbsp;propulsion systems, and&nbsp;optical inter-satellite links,\u201d Amazon said. \u201cIn addition, the satellites are coated in a dielectric mirror film unique to Kuiper that scatters reflected sunlight to help make them less visible to ground-based astronomers.\u201d<\/p>\n<p>The mission profile for KA-1 calls for deploying the satellites safely in orbit and establishing ground-to-space contact. The satellites would then use their electric propulsion systems to settle into their assigned orbits at an altitude of 392 miles (630 kilometers), under the management of Project Kuiper\u2019s mission operations team in Redmond. <\/p>\n<p>Under the current terms of its license from the Federal Communications Commission, Amazon is due to launch 3,232 Kuiper satellites by 2029, with half of those satellites going into orbit by mid-2026.<\/p>\n<p>To accommodate today\u2019s 27-satellite launch, ULA is using the most powerful configuration of the Atlas V rocket, with five solid rocket boosters added to the core booster. Amazon has reserved seven more Atlas V missions for Project Kuiper, and it\u2019s already begun shipping and processing satellites for the next Florida launch.<\/p>\n<p>Amazon has also reserved 38 launches on ULA\u2019s larger Vulcan Centaur rocket, plus more than 30 launches on rockets provided by Arianespace, Blue Origin and SpaceX.<\/p>\n<p>The schedule for satellite production and deployment is so tight that Amazon will probably have to ask the FCC for an extension on the mid-2026 deadline, according to Bloomberg News.<\/p>\n<p>Project Kuiper\u2019s ambitious deployment campaign is part of an effort to catch up with SpaceX\u2019s Starlink satellite broadband network, which already has more than 7,000 satellites in orbit and 5 million subscribers. Eutelsat OneWeb is also going after the market for internet services provided by satellites in low Earth orbit.<\/p>\n<p>Stan Shull, managing director for Alliance Velocity, noted this month that Amazon\u2019s Project Kuiper now leads the list of Seattle-area space ventures when it comes to employment listings. According to Shull\u2019s figures, Project Kuiper accounted for about 47% of the 1,149 open jobs in Washington state\u2019s space industry as of March 31, compared with 21% for Jeff Bezos\u2019 Blue Origin space venture and 19% for Starlink, which manufactures its satellites at SpaceX\u2019s Redmond facility.<\/p>\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\">\n<iframe loading=\"lazy\" title=\"Project Kuiper: Journey to Launch\" width=\"800\" height=\"450\" src=\"https:\/\/www.youtube.com\/embed\/OBhsMZS2y0Y?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen=\"\"><\/iframe><br \/>\n<\/figure>\n<p><em>This is an updated version of a report first published on April 2.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>An Atlas V rocket stands ready to launch Amazon\u2019s Project Kuiper satellites.
