But just as the V-2 rocket was far from the apex of chemical propulsion, the first NTR-enabled spacecraft will be far from the last word in the next chapter of human spaceflight.

Impulse Space is also developing a more powerful thruster, Rigel, for a Mars lander and a larger orbiter vehicle. A robotic mission to Mars will fly no earlier than in 2026 on a Terran R rocket ...

This high thrust allows the rocket to accelerate faster. These systems also have a high specific impulse. Specific impulse measures how efficiently the propellant is used to generate thrust. Nuclear ...

Tom Mueller is a self-described race car guy. Upon retiring from his role as CTO of Propulsion at SpaceX in November 2020, he “mostly wanted to go racing and ride dirt bikes and travel,” he ...

Rocket Propulsion Lab blasts away record ... With a design called “Shockwave,” the team measured a maximum thrust of 3,772 pounds of force and a total impulse of 45,698 pounds of force per second — ...

Impulse Space has raised a massive new tranche of funding as big-name investors bet that moving satellites around in orbit will soon be a high demand service. The startup, which was founded by Tom ...

Impulse Space and Vast will work closely to integrate the propulsion system as a key subsystem of Haven-1, scheduled to launch on a SpaceX Falcon 9 rocket to low-Earth orbit in August 2025 and is ...

Ad Astra Rocket Company has spent over two decades developing the Variable Specific Impulse Magnetoplasma Rocket (VASIMR), a highly efficient electric propulsion system. VASIMR operates by using ...

Nuclear thermal propulsion (NTP) has stood as a promising potential alternative propulsion technology for decades. Chemical rockets have begun to reach their theoretical maximum efficiency, and ...

The space station is scheduled to launch on a Space Exploration Technology Corp. Falcon 9 rocket in August 2025. The propulsion system, designed by Impulse Space, will maintain Haven-1’s ...

HUNTINGTON BEACH, Calif., May 29, 2025--Karman Acquires Industrial Solid Propulsion ("ISP"), a Leading Supplier of Energetic Propulsion Tech for UAS, UAS Intercept & Rocket-Assisted Takeoff ...

According to Universe Today, DRACO's design used a solid high-assay low-enriched uranium (HALEU) to generate lots of heat that turns hydrogen from a liquid to gas (and thus propulsion), providing ...
