Earlier this year, the agency announced a partnership with the Defense Advanced Research Projects Agency, or DARPA, to develop a rocket that uses nuclear propulsion to carry astronaut crews to deep-space destinations like Mars. This type of technology would significantly cut down on the time needed to reach Mars, making long-duration spaceflights less risky for the humans onboard.
. Studies have shown that without the protection of Earth’s atmosphere and magnetic field, humans can receive the equivalent of an entire year of radiation on Earth in just one day in space.
This type of propulsion can create more thrust and is at least three times as efficient as chemical rockets, And though the system runs on nuclear power, Nelson said it would use low-enriched uranium rather than weapons-grade, highly enriched uranium.He added that tests of the nuclear rocket engine would not occur on Earth and would instead take place in space, with safety being the highest priority. The first DRACO demonstration could happen as early as 2027, according to NASA.
