Impulse Space

Today, we’re unveiling our proposed lunar mission architecture to deliver more mass to the Moon, in the near term.  By pairing our Helios kick stage with a new, Impulse-built lunar lander, we’re taking the next step toward mobilizing space, and enabling sustained lunar operations.

We’ve opened a new 20,000 sq. ft. manufacturing facility outside Boulder, Colorado. The site expands Guidance, Navigation, and Control (GNC) development for Mira and Helios. And, it adds multi-axis CNC and precision mill-turn machining for propulsion hardware, including valves used during orbital burns. And we’re growing our team in the region.

@scottgmorton @IndexVentures @Redpoint @ThriveCapital @felicis @AbstractVC Congrats Team Revel! We're glad to be part of the ride. 🚀

Today we announced our $150M Series B led by @IndexVentures with major participation from @Redpoint and returning investors including @ThriveCapital, @felicis, and @AbstractVC. Across aerospace, energy, and manufacturing, engineering teams are pushing what’s possible. The software behind many of these systems hasn’t kept up. Revel gives engineering teams the infrastructure to test and control complex hardware systems with speed and confidence. In just over a year, we’ve built a world-class team, converted every pilot into a customer, and are now expanding the platform across new industries. If you believe great hardware deserves great software, we’re hiring across the board. Read the full announcement here: nytimes.com/2026/02/26/bus…

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! interactive.satellitetoday.com/via/march-2026…

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 nearly complete at our Mojave facility. It's where we'll begin to operate the stage, validate design intent, and characterize stage performance – and move Helios from design into a high reliability, high performance vehicle.

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 @StarfishSpace 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.

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

Congratulations to @rookisaacman. Excited for your leadership of NASA!

“I want people to be able to say that Impulse helped usher in a true Space Age” — @lrocket The new profile from @IntEngineering dives into Impulse Founder & CEO, Tom Mueller's path from Idaho logging country to SpaceX, and now to building the future of in-space mobility at Impulse.

Impulse has received the 2025 @SpaceNews_Inc Icon Award for top Emerging Space Company. The recognition highlights: • Mira’s two engine burns within a single trip around Earth on LEO Express 2 • Caravan rideshare contracts • The upcoming debut of Helios, the kick stage transforming access to MEO, GEO, Cislunar, and beyond. “Impulse Space set the pace this year in a nascent in-space transportation market that is rapidly moving from promise to practice.” — SpaceNews And we’re just getting started. #SpaceNewsIconAwards *Event photography provided by Jason Dixon Photography

🚀 LEO Express 3 is officially underway! Mira has successfully launched aboard the Transporter-15 rideshare mission from Vandenberg Space Force Base. Following separation from SpaceX’s Falcon 9, we’ve received initial telemetry data and confirmed two-way comms, as well as deployment of the solar arrays. The vehicle is healthy and we are moving through commissioning procedures. Stay tuned for mission milestones as Mira’s journey unfolds: impulsespace.com/updates/leo-ex… #LEOExpress3 (Photos provided by @SpaceX)

Impulse President and COO, Eric Romo spoke with @NYSE this week about the evolution of space access, from its military origins to its present role in our daily lives through GPS and other innovations.

Meet the official LEO Express 3 mission patch.  The patch features Mira’s new, upgraded design, with gimbaled solar arrays and a deck built to host and deploy payloads. The three orbital arcs represent LEO → MEO → GEO, reflecting one of LEO Express 3’s objectives: to serve as a bridge between operations in LEO, where Mira has flown to-date, and future flights in high energy orbits, beginning in 2026.   In the background, a dot-work graphic alludes to the appearance of the Milky Way from Earth. But look closer: it’s the outline of California, where Impulse’s headquarters are located and where our company began four years ago.  LEO Express 3 launches soon. Follow along for more updates on our website, link in the thread below.  #MobilizeSpace
