About
Every year, billions of dollars in satellite potential remains locked in low orbits because moving through space remains slow, expensive, and inflexible. Impulse Space exists to revolutionize orbital mobility - the critical 'last-mile' infrastructure that will unlock humanity's future beyond Earth. Founded in 2021 by Tom Mueller, the propulsion legend behind SpaceX's Falcon engines, Impulse is building a new generation of spacecraft that deliver payloads rapidly, reliably, and affordably to any destination in space. The company's fleet of vehicles - including Helios, a high-performance kick stage for LEO-to-GEO transport, and Mira, an agile orbital transfer vehicle - provide the agile, economical mobility that satellites and space stations need to thrive. With 80 employees and growing, and over $525 million raised from investors including Founders Fund and Lux Capital, Impulse is rapidly scaling its operations to deliver missions ranging from LEO Express rideshare services to Cislunar and lunar operations. The team combines veterans of SpaceX, TRW, and other space pioneers with deep expertise in propulsion, avionics, and autonomous systems. By solving mobility within space, Impulse completes the access equation - making space not just reachable, but truly usable for commercial, civil, and government missions that will define the next era of space exploration and commerce.
