NASA and Pentagon to develop nuclear-powered rocket
With the aim of going to the planet Mars, NASA and the Pentagon have entered into a partnership to develop a nuclear-powered rocket.
NASA announced on Tuesday a partnership with the Pentagon to develop a nuclear-powered rocket to send humans to Mars. Space agency boss Bill Nelson said he is partnering with US military research agency Darpa to “develop and test advanced nuclear thermal propulsion technology as early as 2027”.
“With the help of this technology, astronauts could travel to and from deep space faster than ever before,” a capability needed to conduct manned missions to Mars, he said, quoted in a statement. Darpa, the scientific arm of the American army, is at the origin of many innovations of the 20th century, including the Internet.
According to NASA, a thermal nuclear-powered rocket could be three to four times more efficient than conventionally fueled rockets and reduce travel time, an essential part of getting to the Red Planet. In a thermal nuclear rocket, a nuclear fission reactor produces very high temperatures.
Tests for a nuclear rocket 50 years ago
This heat is transferred to a liquid fuel, transformed into gas and — as in a conventional rocket — this is expelled through a nozzle to provide thrust. “Darpa and NASA have a long history of successful collaborations,” said the director of the military research agency Stefanie Tompkins, citing as an example the Saturn V rocket, which sent the Apollo missions to the Moon.
The development of this new type of launch vehicle “will be crucial to more quickly and efficiently transport equipment to the Moon and, subsequently, people to Mars”, she added. NASA conducted tests of a nuclear rocket more than 50 years ago, but the project was halted due to budget cuts and Cold War tensions.
