Solar thermal propulsion is a form of spacecraft propulsion that makes use of solar power to directly heat reaction mass, and therefore does not require an electrical generator as most other forms of solar-powered propulsion do. A solar thermal rocket only has to carry the means of capturing solar energy, such as concentrators and mirrors.
A pulsed nuclear thermal rocket is a type of nuclear thermal rocket (NTR) concept developed at the Polytechnic University of Catalonia, Spain, and presented at the 2016 AIAA/SAE/ASEE Propulsion Conference for thrust and specific impulse (I sp) amplification in a conventional nuclear thermal rocket. [1] The pulsed nuclear thermal rocket is a ...
RD-0410 (РД-0410, GRAU index: 11B91) was a Soviet nuclear thermal rocket engine developed by the Chemical Automatics Design Bureau [1] in Voronezh from 1965 through the 1980s using liquid hydrogen propellant. [2] The engine was ground-tested at the Semipalatinsk Test Site, [3] and its use was incorporated in the Kurchatov Mars 1994 crewed ...
According to Lockheed Martin and BWXT, there are considerable efficiency and time gains from the nuclear thermal propulsion. [10] [11] NASA believes the much higher efficiency will be two to three times more than chemical propulsion, [5] and the nuclear thermal rocket is to cut the journey time to Mars in half. [12]
Project 242 studied the application of this propulsion system to a crewed mission to Mars. [20] Preliminary results were very satisfactory and it has been observed that a propulsion system with these characteristics could make the mission feasible. Another study focused on production of 242m Am in conventional thermal nuclear reactors. [21]
Diagram of a MMRTG. The multi-mission radioisotope thermoelectric generator (MMRTG) is a type of radioisotope thermoelectric generator (RTG) developed for NASA space missions [1] such as the Mars Science Laboratory (MSL), under the jurisdiction of the United States Department of Energy's Office of Space and Defense Power Systems within the Office of Nuclear Energy.
Project Timberwind aimed to develop nuclear thermal rockets. Initial funding by the Strategic Defense Initiative from 1987 through 1991 totaled $139 million (then-year). [1] The proposed rocket was later expanded into a larger design after the project was transferred to the Air Force Space Nuclear Thermal Propulsion (SNTP) program.
Examples of concepts that use nuclear power for space propulsion systems include the nuclear electric rocket (nuclear powered ion thruster(s)), the radioisotope rocket, and radioisotope electric propulsion (REP). [6] One of the more explored concepts is the nuclear thermal rocket, which was ground tested in the NERVA program.
