Timber Wind: America’s Return to Nuclear Thermal Rockets

 Hello, and welcome to Beyond NERVA! Today, we’re continuing to look at the pebble bed nuclear thermal rocket (check out the most recent blog post on the origins of the PBR nuclear thermal rocket here)! Sorry it took so long to get this out… between the huge amount of time it took just to find […]

Pebblebed NTRs: Solid Fuel, but Different

Hello, and welcome back to Beyond NERVA! Today, we’re going to take a break from the closed cycle gas core nuclear thermal rocket (which I’ve been working on constantly since mid-January) to look at one of the most popular designs in modern NTR history: the pebblebed reactor! This I should have covered between solid and […]

Electric Propulsion Part 2: Electrostatic Propulsion

Hello, and welcome back to Beyond NERVA! Today, we finish our look at electric propulsion systems by looking at electrostatic propulsion. This is easily the most common form of in-space electric propulsion system, and as we saw in our History of Electric Propulsion post, it’s also the first that was developed. I apologize about how […]

Electric Propulsion: The Oldest “Futuristic” Propulsion Possibility

Hello, and welcome back to Beyond NERVA. Today, we are looking at a very popular topic, but one that doesn’t necessarily require nuclear power: electric propulsion. However, it IS an area that nuclear power plants are often tied to, because the amount of thrust available is highly dependent on the amount of power available for […]
