Nuclear thermal rocket - Wikipedia
WEBA nuclear thermal rocket (NTR) is a type of thermal rocket where the heat from a nuclear reaction replaces the chemical energy of the propellants in a chemical rocket. In an NTR, a working fluid, usually liquid hydrogen, is heated to a high temperature in a nuclear reactor and then expands through a rocket nozzle to create thrust.
DARPA and NASA Aim to Test Nuclear Rocket by 2026
WEBAug 7, 2023 · Such a furnace could expand a trickle of 20-kelvin liquid hydrogen into a tornado of 2,700-kelvin gas, enabling a manageable amount of propellent to provide powerful thrust halfway to Mars, then to reverse the thrust to decelerate.
NASA and DARPA will build a nuclear rocket by 2027 | Space
WEBJan 24, 2023 · NASA and DARPA announced a collaboration to demonstrate a working nuclear thermal rocket by 2027 with the goal of sending humans to Mars as quickly as possible.
WEBThe Centrifugal Nuclear Thermal Rocket (CNTR) is designed to enable advanced space exploration missions while simultaneously minimizing engine development risk. The CNTR is essentially a high performance nuclear thermal propulsion (NTP) system, with propellant heated directly by the reactor fuel.
NASA, DARPA Will Test Nuclear Engine for Future Mars Missions
WEBJan 24, 2023 · NASA and the Defense Advanced Research Projects Agency (DARPA) announced Tuesday a collaboration to demonstrate a nuclear thermal rocket engine in space, an enabling capability for NASA crewed missions to Mars.
Nuclear Thermal Propulsion Systems - Glenn Research Center
WEBDec 18, 2023 · Typically when the term “Nuclear Thermal Propulsion” (or NTP) is used, it is in reference to in-space propulsion systems that rely upon a low molecular weight (typically hydrogen) fuel that flows through a reactor to generate heat due to the nuclear fission processes and eventual thrust.
6 Things You Should Know About Nuclear Thermal Propulsion
WEBDec 10, 2021 · NTP systems work by pumping a liquid propellant, most likely hydrogen, through a reactor core. Uranium atoms split apart inside the core and release heat through fission . This physical process heats up the propellant and converts it to a gas, which is expanded through a nozzle to produce thrust.
