Seattle-based Ultra Safe Nuclear Technologies (USNC-Tech) has developed a concept for a new Nuclear Thermal Propulsion (NTP) engine and delivered it to NASA. Claimed to be safer and more reliable than previous NTP designs and with far greater efficiency than a chemical rocket, the concept could help realize the goal of using nuclear propulsion to revolutionize deep space travel, reducing Earth-Mars travel time to just three months.
Because chemical rockets are already near their theoretical limits and electric space propulsion systems have such low thrust, rocket engineers continue to seek ways to build more efficient, more powerful engines using some variant of nuclear energy. If properly designed, such nuclear rockets could have several times the efficiency of the chemical variety. The problem is to produce a nuclear reactor that is light enough and safe enough for use outside the Earth's atmosphere – especially if the spacecraft is carrying a crew.
According to Dr. Michael Eades, principal engineer at USNC-Tech, the new concept engine is more reliable than previous NTP designs and can produce twice the specific impulse of a chemical rocket. Specific impulse is a measure of a rocket's efficiency.
To fuel the concept, UNSC-Tech uses a Fully Ceramic Micro-encapsulated (FCM) fuel to power the engine's reactor. This fuel is based on High-Assay Low Enriched Uranium (HALEU), which is derived from reprocessed civilian nuclear fuel and is enriched to between 5 and 20 percent – greater than that of civilian reactors and less than that of naval reactors. The fuel is then encapsulated into particles coated with zirconium carbide (ZrC).

Uhhh, Project Orion, right?
“Would be great for freight hauling, getting material into place in orbit, especially fuel, robots, support machinery”
Robotic barges should pre-position redundant stockpiles of shelters, supplies, power sources, vehicles and robots (and probably start up farms); before any people land to occupy a Mars base.
With current rockets, it is a two year trip, each way - and even that only within certain launch windows.
The kind of propulsion in this article could make Mars much more feasible, and much more survivable.

So when I develop a way to fold space, I'll get back to you.
And don't tell me some Jabba the Hut looking thing that does Spice has already done it, malarky!
