SAN DIEGO – 20 Jan 2025 -General Atomics Electromagnetic Systems (GA-EMS) announced today that it has successfully executed several significant high-impact tests at NASA’s Marshall Space Flight Center (MSFC) to advance the development of Nuclear Thermal Propulsion (NTP) reactor technology for...
In nuclear thermal propulsion (NTP), the super-hot pressurized hydrogen is funneled out a nozzle to create a powerful thrust. The mechanics of an NTP engine are much simpler and vastly more efficient than chemical propellent engines. In fission surface power systems, the heat...
This enables deriving a motivation for the use of Nuclear Thermal Propulsion (NTP) relying on nuclear power sources. Then, a summary of major families of NTP systems is established on the basis of a literature survey. These families are distinguished by the nature of their power source, the ...
NASA is still shooting for the Red Planet, aiming to get astronauts there by the late 2030s or early 2040s. And it still viewsnuclear thermal propulsion as a key breakthroughthat could make this goal more attainable, by slashing the travel time to and from the Red Planet. ...
The Pentagon wants to extend the reach of its satellites tens of thousands miles toward the moon. And it’s working on a high-tech, atomic-powered “nuclear thermal propulsion” engine to make it possible. The military’s goal is to deploy maneuverable satellites into the vast space between ...
The conceptual design for the first-of-a-kind engineering of Thermal Engine Rocket Adventure (TERA) is described. TERA comprising the Battery Omnibus Reactor Integral System (BORIS) as the heat resource and the Space Propulsion Reactor Integral System (SPRIS) as the propulsion system, is one of...
GA-EMS’ design isn’t the only one being considered, though. NASA and DARPA announced in 2023 that they were working on a nuclear thermal rocket engine, with a planned launch demonstration as early as 2027. The big drive behind these new propulsion technologies is that a...
nuclear thermal rockets. However, in spite of the petition-signers' interest, the project is small. Its budget for hardware and contractors this year is just under $3 million. "It's really in the early stages," Houts told TechNewsDaily. "There are no definite plans to use the engine."...
