  • Nasa has developed and tested a new propulsion system designed for deep space missions.
  • RDRE system has the potential to power both human landers and interplanetary vehicles going to deep space destinations like mars and the Moon.
  • Reportedly, Nasa is also working on nuclear-powered spacecraft.
As Nasa gears up for a return to the moon with the Artemis mission, the administration has announced that researchers have successfully developed and tested a new type of rocket supersonic rocket engine called a Rotating Detonation Rocket Engine (RDRE) that will help Nasa with deep space missions.

The point of RDRE designs is to use less fuel while also providing more thrust than the current propulsion system that Nasa and other companies rely on. Using less fuel makes it easier to prepare these spacecraft for deep space missions, as you can mete out smaller amounts of fuel that won’t weigh down the rocket while it is lifting off.

Exploring the differences between RDRE and traditional propulsion systems

The Rotating Detonation Rocket Engine (RDRE) is a new propulsion system developed by NASA. It works by rapidly rotating and detonating a mixture of fuel and oxidizer in a continuous combustion cycle, generating high-pressure and high-temperature gases that provide thrust. The RDRE has the potential to be much more efficient and powerful than traditional rocket engines, making it a promising technology for future space missions.

Also, the RDRE system can power both human landers and interplanetary vehicles designated for deep space missions such as Mars and Moon.

Currently, engineers from Nasa and space tech company IN Space are confirming data from RDRE test fires that were conducted back in 2022.


During the test, the engine was fired over twelve times for a total duration of 10 minutes. The RDRE system achieved its primary objective of operating long while withstanding the extreme heat and pressure environments generated by detonation.

During the test, the RDRE system produced over 4,000 pounds of thrust for a minute at an average chamber pressure of 622 pounds per square inch, which is the highest pressure rating for this design.

Additional milestones achieved during the test include the successful performance of deep throttling and internal ignition. This demonstration also brings technology closer to being used in future flight vehicles, enabling Nasa and other space agencies to move more payload and mass to deep space stations. This will also make space exploration more sustainable.

With the success of this test, Nasa is now looking to build a fully reusable 10,000-pound RDRE system that will match the performance of traditional liquid rocket engines. If upcoming tests prove successful, they could revolutionize how we think about deep space travel.

This isn’t the only way Nasa is looking to revolutionize deep space travel. The space agency is reportedly working on nuclear-powered spacecraft, which could allow spacecraft to travel further distances without needing liquid fuel. It would also shorten the journey to Mars from six months to just 45 days.
