Earlier today, Jim Bridenstine, Chief Executive Officer of Quantum Space, shared a note with employees on the company's flight heritage and the status of Ranger Prime, our next mission. We wanted to share it publicly and provide more insight into where we are and where we are going as a company.

About a month ago, I joined Quantum Space because I believe this team is building something consequential as a critical capability to ensure American security in space and on Earth. The capabilities being built by Quantum Space employees will shape how America’s spacecraft operate in space for the next generation. As I get settled in, I want to share where we stand: our flight heritage, what we learned, and where Ranger Prime is headed.
Ranger Prime is Quantum Space’s first flight of our Ranger platform. The mission will validate spacecraft performance, payload hosting, and data collection. It will also demonstrate maneuvering and rendezvous and proximity operations using our custom propulsion system. In the press release announcing my appointment, we also announced that launch of Ranger Prime is currently scheduled no earlier than second quarter (Spring) of 2027.
I have reviewed our design and manufacturing progress and am confident we are on target for this launch date.
This mission will be an exciting demonstration of Quantum’s end-to-end mission capability. Quantum will operate Ranger Prime from our scalable mission control center, commanding the vehicle through a series of propulsive maneuvers all while conducting payload operations. We will validate our ability to design, launch, commission, and operate our platforms, and Ranger Prime will become a fleet-leader for broader autonomy and computing-intensive missions.
Our Ranger vehicles are designed to operate across LEO, MEO, GEO, and cislunar space. They are modular, refuelable, and built for sustained maneuver. The DARPA LASSO and FLOW awards and our selection to compete for the Space Force Andromeda program — an IDIQ vehicle with a ceiling value of $6.2 billion or more — are external validations that the market need is real and that Quantum Space is positioned to serve it.
While Ranger Prime will be our first Ranger mission, it will not be our first hardware in space.
In May 2024, Quantum Space launched its first spacecraft, a Scout satellite under the mission banner of Sentry (originally designated QS-1). This inaugural mission was designed to collect space domain awareness data and validate foundational capabilities on orbit.
The Sentry mission flew with a plaque aboard the Scout spacecraft dedicated to Steve Jurczyk, a dear friend, former NASA colleague, and the founding CEO and co-founder of Quantum Space, who sadly passed away from cancer before the launch. Steve built the foundation this company stands on. That mission carried his name into orbit, and we are grateful for everything he gave this team.
Following successful deployment of the Sentry spacecraft, Quantum Space established initial contact, verified spacecraft health, and began on-orbit commissioning activities. During commissioning, the spacecraft experienced a power-system anomaly that impacted mission performance. The Quantum Space mission operations team successfully stabilized the spacecraft and conducted an extensive six-month investigation, including fault-tree analysis, hardware-in-the-loop testing using an in-house flatsat, software updates, and numerous on-orbit recovery attempts.
While the anomaly shortened the planned one-year+ mission, Sentry provided valuable flight heritage and operational insights that strengthened our spacecraft design, testing, and mission assurance processes, directly contributing to the development and risk reduction of our next-generation Ranger platform. It was a meaningful moment of learning for the company and the team. That is how serious engineering organizations operate. You fly, you learn, you build better.
America’s adversaries have spent the last decade developing the ability to surveil, target, and threaten our on-orbit assets. A space architecture of satellites in fixed and predictable orbits is a strategic liability. Ranger is the answer to that problem: a maneuverable platform that can persist, adapt, and operate dynamically across the orbital environment.
The Theory of Competitive Endurance requires us to avoid operational surprise, deny first-mover advantage, and maintain freedom of action in every orbit. Ranger is purpose-built to deliver on each of those pillars. Any orbit, anytime.
Our Hawthorne propulsion work, our Rockville engineering base, and our future locations are not separate stories. They are one story: a company building the industrial capacity to produce Ranger at scale, in the United States, in support of the missions that matter most.
I have spent my career in and around space — in the cockpit, in Congress, and at NASA. I have not seen a company doing what this team is doing. We have learned hard lessons. We have a platform worth believing in and a team ready to deliver it.
Ranger Prime launches in 2027. Let’s make sure we are ready.
