Impulse Space

On LEO Express 2, Mira recently completed the longest on-orbit burn in program history at 223 seconds. We performed the maneuver to adjust orbital parameters in preparation for future capability demonstrations. Inclination changes require big delta-v. They allow us to shift planes, set up new geometries, and expand what this vehicle can support on orbit. Lining up what comes next.

A sustained presence on the Moon depends on delivering infrastructure to the surface at cadence. NASA - National Aeronautics and Space Administration's phased approach calls for regular cargo, surface systems, and scalable logistics. That means delivering rovers, power systems, communications, and habitation modules to the lunar surface. Our approach combines our Helios kick stage with an Impulse-built lander to deliver multiple tons of cargo per mission. Helios transports the lander from LEO to lunar orbit, enabling delivery to the surface without in-space refueling. A repeatable architecture aligned with how lunar operations scale.

Impulse Space has been named one of Fast Company's Most Innovative Companies of 2026. This recognition is a testament to our engineers, technicians, and operators who are turning ambitious ideas into on orbit space mobility solutions. There’s tremendous momentum across our factories and test sites. More vehicles in production, more missions ahead, and more hard problems to solve.

We’ve opened a 20,000 sq. ft. manufacturing facility outside Boulder, Colorado.  The site expands our Guidance, Navigation, and Control (GNC) development for Mira and Helios.  Spacecraft built at Impulse rely on GNC systems developed by our Colorado team to sense, orient, and maneuver on orbit. This includes the star tracking, Safe Mode, inertial navigation, and precision delta-V control flying today on our LEO Express missions.  The facility also adds multi-axis CNC and precision mill-turn machining for propulsion hardware, including valves used during orbital burns.  We’re closing the loop between development and mission execution at our Colorado campus.   And we’re expanding our team in the region.  Read more: https://lnkd.in/gk_TZw_g

Julia Vyborny, Director of Propulsion at Impulse Space, has been recognized in Via Satellite's Celebrating Women in Satellite 2026! Julia sets a high bar for technical rigor and ownership as we build the future of in-space mobility. Congratulations, Julia!

The next challenge in space is on-orbit mobility. When spacecraft can maneuver precisely, reliably, and responsively, everything accelerates: stations, satellites, logistics, exploration, and the orbital economy at large. We’re excited to provide the propulsion system for Vast’s Haven Demo and Haven-1. Building the enabling infrastructure that lets others unlock their missions is how we move toward a real Space Age. #MobilizeSpace 

Phase 1 of the Helios vertical test stand is nearing completion at our Mojave facility. This is where our team will begin to operate the stage, validate design intent, and characterize stage performance. It's a key step in moving Helios from design into a high reliability, high performance vehicle. Phase 2 build is next. 

Highly-maneuverable, extremely photogenic. Take a look at what our LEO Express 2 Mira saw while closing in on the LEO Express 1 Mira – on our fully autonomous RPO mission with Starfish Space. Starfish’s software enabled Mira to perform close-proximity maneuvers, with a single camera and closed-loop GNC software guiding our spacecraft within ~1250 meters of one another in LEO. Mira executed the approach after completing its primary delivery objectives, validating its ability to perform responsive, high-precision RPO on orbit.

On-Orbit Update: Vehicle commissioning is underway and customer payload deployments have begun on the LEO Express 3 Mission.     After separation from the launch vehicle, our team used new, Impulse-built radios to make contact with Mira. The spacecraft autonomously deployed its new dual solar arrays and established a sun-pointing attitude and power-positive state. During the initial phase of our commissioning process, Mira’s star trackers produced noisier measurements than expected, leading to higher RCS propellant expenditure than desired for this phase of the mission. After detecting this trend, our team pivoted to an alternate attitude control scheme and is continuing to proceed through additional commissioning activities. Having expended the majority of the nitrous oxide as a result of the incident, Mira will not be able to perform main thruster burns.      We’ve also begun LEO Express 3 customer missions, with 2 of 3 FOSSASats successfully deployed into their target orbits. Mira remains in a stable, sun-pointed and power-positive state. Read the full update here: https://lnkd.in/g_2H_bnm 

2025 moved fast—and so did we. This year, we launched the LEO Express 2 and 3 missions, bringing us to a total of three Mira spacecraft on orbit, executed a first-of-its-kind autonomous RPO, and upgraded Mira to expand performance and unlock mission profiles across higher energy orbits. In our Helios program, we proof tested the Run Stage tank test article, validating the tank structural design and manufacturing processes. This primary structure is representative of the flight tank for the fully-manifested Caravan 1 maiden flight of Helios. And, our Deneb engine test article executed 165 powerpack hotfire tests across 13 builds. We shared our vision beyond GEO, with an Impulse-designed lander architecture to deliver more mass to the moon and help build out a sustained lunar presence. We raised a $300 million Series C, bringing total funding to over half a billion dollars, and doubled our team. We tripled our testing footprint in Mojave, opened a new facility in Colorado expanding capabilities across precision manufacturing, optics development, GNC, and simulation, and secured additional space in Redondo Beach to support our scaling production. We initiated major mission contracts and partnerships with NASA, SES, Anduril, Astranis, Infinite Orbits, Lodestar, and more. We were named one of Fast Company’s Next Big Things in Tech, SpaceNews’ Emerging Space Company of the Year, and LA Business Journal’s Disruptor of the Year. And that’s just a few of the highlights. We’re excited to bring you inside these moments and more in 2026. Happy New Year from all of us at Impulse! #MobilizeSpace
