NASA and DARPA are working on a nuclear-powered rocket that could go to Mars

The technology would also have significant national security implications

Washington Post By Christian Davenport, February 3, 2023

“……………………………………… If NASA’s going to get to Mars, it needs to find a way to get there much faster. Which is one of the reasons it said last week that it is partnering with the Pentagon’s Defense Advanced Research Projects Agency on development of thermonuclear propulsion technology.

………………. DARPA, the arm of the Defense Department that seeks to develop transformative technologies, has been working on the program since 2021, when it awarded three contracts for the first phase of the program to General Atomics, Lockheed Martin and Blue Origin, the space company founded by Jeff Bezos. (Bezos owns The Washington Post.) A nuclear-powered rocket would use a nuclear reactor to heat propellant to extreme temperatures before shooting the fuel through a nozzle to produce thrust.

………………….. The program is called DRACO, for Demonstration Rocket for Agile Cislunar (or in the vicinity of the moon) Operation……………………..

The agencies hope they’ll be ready to demonstrate their work with a spaceflight in 2027.

NASA is also working with the Department of Energy on a separate project to develop a nuclear power plant that could be used on the moon and perhaps one day on Mars.

But getting to Mars is exceedingly difficult, and despite claims from NASA for years that it was gearing up to send astronauts there, the agency is nowhere close to achieving that goal.

One of the main obstacles is the distance. Earth and Mars are only on the same side of the sun every 26 months. But even at their closest points, a spacecraft would have to follow an elliptical orbit around the sun that, as Tory Bruno, the CEO of the United Launch Alliance, wrote in a recent essay, will require “a great sweeping arc of around 300 million miles to arrive.”

……………………………. . The need for spacecraft that can maneuver away from the enemy has become clear during the war in Ukraine.  https://www.washingtonpost.com/technology/2023/02/03/nuclear-rocket-darpa-nasa/
