The round was co-led by 137 Ventures and BANNER VC, bringing the company\u2019s total capital raised to over $1 billion. The funding will support hiring and manufacturing growth as the company scales its effort to build in-space mobility infrastructure: the vehicles, propulsion systems, and operational architecture that determine where and how spacecraft move after launch.<\/p>\n<p>With three missions flown and hundreds of millions of dollars in customer contracts,&nbsp;Impulse is growing to meet surging demand for in-space mobility across commercial, civil and government sectors. Over the past decade, launch has become more accessible and frequent. But once in orbit, spacecraft have remained constrained in their ability to move. Historically, spacecraft have been locked into a single orbit following launch or faced with slow, expensive transfers.<\/p>\n<p>In order to accelerate humanity\u2019s future beyond Earth, unlock a robust space economy, and realize a true space age, a new layer of orbital infrastructure must be developed: spacecraft that are purpose-built for in-space mobility. Impulse is designing, building, testing, and flying those spacecrafts. Advanced in-space mobility \u2013 the ability to move quickly, precisely, responsively, and affordably after launch \u2013 is a required capability for the next phase of the space economy. It allows spacecraft to be placed, repositioned or re-tasked, and operated with unprecedented flexibility. And with that, it transforms how missions are designed and unlocks new opportunities across commercial, civil, and government missions \u2013 both in and well beyond Earth\u2019s immediate orbits.<\/p>\n<div class=\"widget-layout related-content-also-read-box my-3\">\n<h4 class=\"mb-0\">Also Read: What is Extravehicular Activity (EVA)?<\/h4>\n<\/div>\n<p><em>\u201cWe\u2019re building more than spacecraft: we\u2019re building the economic and technical engine that will power humanity\u2019s expansion into space,\u201d <strong>said Tom Mueller, founder and CEO of Impulse Space<\/strong>. \u201cFrom Earth orbit to the Moon and beyond, the ability to move quickly, precisely, and affordably on orbit is the fundamental capability that will unlock a true space age.\u201d<\/em><\/p>\n<p>Impulse\u2019s initial fleet of spacecraft span precision maneuvering, rapid long-haul transport, and rideshare access to higher-energy destinations.<\/p>\n<ul>\n<li>Mira, the company\u2019s precision maneuvering spacecraft, has flown multiple missions, executing record-setting orbit changes and complex in-space operations including autonomous rendezvous and proximity operations (RPO).<\/li>\n<li>Helios, a high-energy kick stage scheduled for first flight in 2027, is designed to deliver payloads to distant orbits on dramatically shorter timelines and much more affordably than conventional approaches.<\/li>\n<li>Caravan, the company\u2019s rideshare program, is designed to reduce the cost of access to higher-energy orbits such as GEO.<\/li>\n<\/ul>\n<p>Alongside its spacecraft, Impulse is developing a family of propulsion systems tailored to different mission profiles:<\/p>\n<ul>\n<li>Saiph for precision maneuvering and orbital repositioning.<\/li>\n<li>Deneb for high-energy, long-distance transport.<\/li>\n<li>Rigel for throttleable applications such as landers and responsive maneuvers.<\/li>\n<\/ul>\n<p>With several additional spacecraft and propulsion systems in development, Impulse is building the full-spectrum in-space mobility infrastructure required for a future where movement in space is fast, flexible and routine.
