WASHINGTON \u2014 Portal Space Systems says it will develop a highly maneuverable satellite bus, with a first flight planned for late 2026.<\/p>\n
Portal announced Nov. 5 the Starburst, a small satellite with one kilometer per second of delta-V, or change in velocity, to maneuver between orbits. The company described Starburst as \u201cESPA-class,\u201d meaning it is compatible with the EELV Secondary Payload Adapter commonly used for rideshare payloads.<\/p>\n
The first Starburst mission, Starburst-1, is scheduled for the fourth quarter of 2026 on SpaceX\u2019s Transporter-18 rideshare mission. Starburst-1 will operate in a sun-synchronous orbit for a year to demonstrate capabilities such as rendezvous and proximity operations, rapid orbital changes and retasking.<\/p>\n
Starburst-1 will carry payloads for two companies. TRL11 will provide cameras and edge processing systems to monitor spacecraft health, while Zenno Astronautics will demonstrate superconducting magnets for attitude control.<\/p>\n
Starburst is designed to complement Portal\u2019s Supernova vehicle, which uses solar thermal propulsion to provide both high thrust and high delta-V for orbital transfers. Some systems developed for Supernova will be tested on Starburst, including thrusters that will serve as the reaction control system for Supernova and as the main translational propulsion for Starburst.<\/p>\n
\u201cOur strategy is to deliver what customers need now and accelerate what they\u2019ll need next,\u201d Jeff Thornburg, chief executive of Portal Space Systems, said in a statement. \u201cStarburst gives operators a maneuverable bus that supports proliferated architectures in the orbit that matters to them. Supernova brings the trans-orbital reach.\u201d<\/p>\n
\u201cFlying Starburst-1 in 2026 lets us field capability quickly and advance the shared systems that raise confidence for Supernova\u2019s 2027 debut,\u201d he added.<\/p>\n
Portal previously announced plans to test Supernova technologies in early 2026 on a Vigoride tug by Momentus. That flight will test avionics, sensors and other systems separate from Supernova\u2019s propulsion system, Thornburg said in June<\/a>. At the time, he said a second test flight was planned for later in 2026 with similar objectives \u201cbut in a more robust way.\u201d<\/p>\n \n\tRelated<\/p>\n","protected":false},"excerpt":{"rendered":"WASHINGTON \u2014 Portal Space Systems says it will develop a highly maneuverable satellite bus, with a first flight…\n","protected":false},"author":2,"featured_media":282411,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[48],"tags":[149296,79,722,193],"class_list":["post-282410","post","type-post","status-publish","format-standard","has-post-thumbnail","category-space","tag-portal-space-systems","tag-science","tag-sn","tag-space"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/282410","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/comments?post=282410"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/282410\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media\/282411"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media?parent=282410"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/categories?post=282410"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/tags?post=282410"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
