Transforming the way we access space


But the aerospace industry is stuck in the past, still relying on wasteful technology to explore the stars. These modern challenges require modern solutions. At RocketStar, we’re rethinking space travel from the inside out. And that starts by improving upon the engines that power us to the stars.

FireStar™ Fusion Drive

Revolutionizing Space Propulsion: Introducing the World's First Fusion-Enhanced Space Thruster, the FireStar™ Fusion Drive.

This is not incremental progress. It is a big leap into the future of space travel.

RocketStar isn't just improving spacecraft engines – we're reinventing them. Introducing a groundbreaking achievement in space propulsion technology – the FireStar™ Fusion Drive, the world's first electric propulsion device enhanced with nuclear fusion.

The FireStar™ Fusion Drive takes our base water-fueled pulsed plasma thruster to new heights by harnessing the power of aneutronic nuclear fusion. By introducing boron into the thruster's exhaust, high-speed protons generated from ionized water vapor collide with boron nuclei, triggering a fusion reaction that significantly boosts the thruster's performance. This fusion process, like an afterburner in a jet engine, transforms boron into high-energy carbon, which rapidly decays into three alpha particles. The result? A remarkable 50% improvement in thrust compared to our FireStar™ Foundation thruster.


The Future of Space Propulsion Starts Here

At RocketStar, we are committed to pushing the boundaries of space propulsion technology. With the FireStar™ Drives, we are not just improving upon existing systems, but revolutionizing the way we explore and navigate the final frontier.

Join us on this exciting journey as we continue to innovate and transform the future of space travel.

Phoenix Eye™ SignalBoost: The LPI/D Solution

Imagine a scenario where if you click the mic on your radio, you’re dead! This is a scenario that Special Operators and others with covert or clandestine missions face. How do you communicate without notifying the enemy of your presence?

The Phoenix Eye™ SignalBoost system from RocketStar provides Low Probability of Intercept/Detect (LPI/D) capabilities for Tactical Radio Communications. At the heart of our innovation is proprietary COTS software developed for deep space comms that has been adapted to detect signals tens of dB below the noise floor.

Phoenix Eye™ SignalPrint: Know Who’s Talking

Hackers have busted into your mesh network and captured crypto keys for your mission critical system. They can’t access your hardware, so they use identical radios to transmit the signals from the expected location. Your system has an authenticated message from the correct hardware in the right place but it’s a cyber-attack! How do you stop it before it starts?

The Phoenix Eye™ SignalPrint system from RocketStar provides unique identification of specific transmitters even if they are all identical in design, manufacture, configuration, software, and crypto. Its proprietary COTS software can identify the unique “fingerprints” of any electronic transmitter giving you the ability to identify and track individual radio emitters with unprecedented accuracy.

Phoenix Eye™ SyncWave: Digital Signal Processing Software

Electronically Scanned Antenna (ESA) receivers allow clear reception by combining weak signals, but their signal gathering power suffers dramatically from grating lobes caused by carrier phase differences, which severely limits antenna design options.

PhoenixEye™ OmniPNT: The GPS-Denied PNT Solution

Imagine navigating anywhere on Earth without access to GPS signals. RocketStar has solved this persistent problem by creating a highly innovative Alternative Positioning, Navigation & Timing (APNT) system, the Phoenix Eye™ OminiPNT that makes it possible. It’s a Commercial Off-the-Shelf (COTS) software solution that uses radio waves from celestial objects like the sun, moon, planets, satellites, pulsars and other signals of opportunity to determine location (latitude, longitude, altitude and time).

Unlike traditional bell cone engines the space industry has used for the past 70 years, our Aerospike engines combine efficiency and power, providing 25-35% more thrust over conventional rocket engines without using extra fuel to do so.



The combustion chambers in the Aerospike can be controlled individually, meaning these engines are capable of thrust vectoring, eliminating the need for heavy gimbals or actuators that weigh down a rocket. Aerospikes perform 20% better than conventional rocket engines. And this increased performance is possible at any altitude thanks to the Aerospike’s ability to adjust to changing atmospheric pressure.

RS Team Launch 2


Instead of waiting two months or more for a traditional rocket to be ready for reuse, the revolutionary Aerospike engine allows our single-stage-to-orbit (SSTO) rockets to be ready to fly again within two weeks after use. This technology will allow for faster, cheaper and more reliable space transportation, bringing the stars closer to all of us than ever before.

RocketStar Announces Successful Demonstration of Fusion-Enhanced Pulsed Plasma Electric Propulsion

RocketStar Inc. has successfully demonstrated the FireStar Drive, a groundbreaking electric propulsion unit for spacecraft that uses nuclear fusion-enhanced pulsed plasma. This innovative device significantly boosts the performance of RocketStar's base water-fueled pulsed plasma thruster by utilizing a unique form of aneutronic nuclear fusion. The base thruster generates high-speed protons through the ionization of water vapor. When these protons collide with the nucleus of a boron atom, the atom undergoes fusion, transforming into a high-energy form of carbon that rapidly decays into three alpha particles. By introducing boron into the thruster's exhaust, the FireStar Drive enables this fusion process. Similar to the way an afterburner enhances thrust in a jet engine by introducing fuel into the exhaust, the fusion occurring in the thruster's exhaust significantly improves its performance.

RocketStar aims to launch its developmental Cowbell rocket from this multi-use launchpad in Cape Canaveral, Florida.
TAMPA, Fla. — New York-based RocketStar plans to launch its aerospike-powered rocket for the first time this fall, carrying a prototype satellite for resource-mapping startup Lunasonde on a brief suborbital trip.

The 12-meter rocket that RocketStar calls Cowbell aims to reach 21,000 meters on its test flight, depending on final safety requirements from NASA for launching from Launch Complex 48 — a multi-use launchpad in Cape Canaveral, Florida.

Space Travel Aided by Plasma Thrusters: Past, Present, and Future
Although the basic concept of operation for plasma thrusters has not changed since their first demonstration, much advancement has been made over the years due to extensive research, design, testing, and engineering. Goebel and Katz consider ion and Hall thrusters “more modern electric engines that are finding increasingly more applications.”

Further understanding the principles of operation and seeking ways to improve the technology for future advanced applications continue to be the challenges facing many private companies, government institutions, and universities across the world.

Are reusable rockets the key to creating more jobs?
By John Aidan Byrne
Chris Craddock has a dream, and it’s out of this world.

The Wall Street money man is on the cutting edge of advances in cost-saving and reusable rockets, which land safely and are ready quickly for the next launch.

“It doesn’t drop a piece as it flies into orbit like the Saturn 5 did on the Apollo mission,” Craddock told The Post as he prepares for the next test. “It’s like a commercial airplane that flies to the destination, lands, refuels, then flies to the next destination.”

Craddock, 38, says he has leapfrogged his rivals, recently moving from concept to launch within six months with his proprietary, the 3-D-printed “aerospike” engine.

“If I get my way, thousands of jobs will be created,” said Craddock, who grew up in Babylon, Long Island, sadly watching military aerospace industrial players like Northrop Grumman shed thousands of middle-class jobs.

“This will bring manufacturing back to Long Island in a big way,” added Craddock, now a Manhattan resident. “It won’t be just building some nameless widget for a company. People will have pride that they are advancing humanity through rockets.”

RocketStar Wants to Make Going to Space a One-Step Process
RocketStar has its sights set on "single stage to orbit," building a rocket that can leave the planet without requiring multiple stages. That's one of the big goals of rocketry that could make reaching space cheaper and more accessible for everybody, but so far, no one has been able to do it.
