And just like that, I have a new answer to what I’d paint on the side of a 1970's van.
It seems roving around the Martian surface just isn’t good enough; we’ve got to have some face time with the little red guy. NASA announced it would work with the Defense Advanced Research Projects Agency back in January to develop a nuclear propulsion rocket travel three times faster than traditional liquid fuel rockets.
The program has been dubbed DRACO, short for Demonstration Rocket for Agile Cislunar Operations.
The system uses high heat from a fission reactor to turn liquid propellant into a gas, which is then funneled through a nozzle to power the spacecraft.
This type of propulsion can create more thrust and is at least three times as efficient as chemical rockets, according to NASA. That means needing to carry less fuel onboard, which frees up room to haul more equipment, science experiments or other cargo to the Martian surface.
“It can completely change the game of how people think about what is possible in space — what you can carry, how quickly you can get there,” DARPA Director Stefanie Tompkins said. “You have much more flexibility in getting where you want, when you want.”
The scientist goes on to call the technology safe because it would use low-enriched uranium rather than highly enriched, weapons grade uranium. Which...sure. Why not. LEU is what goes into nuclear reactors and none of those have ever posed a health risk to humans, right?
Using this form of rocket would cut travel time to the Red Planet from an eight months to just two and a half, exposing astronauts to much less risk and cosmic radiation. It would also give them more time to focus on boots-on-the-Martian-soil type work, and allow astronauts to bring more stuff with them since they wouldn’t have to haul around a ton of fuel.
The European Space Agency is also betting on nuclear to power its ambitions for deep space research. Nuclear power isn’t our only option for traveling deeper into the solar system; NASA is also fooling around with a rotating detonation rocket engine, or RDRE.
