An experimental nuclear rocket from the 70s nearly doubled our "payment energy". It should greatly reduce the initial and total mass portions of the rocket equation as well. I don't have all of the numbers to punch into the rocket equation to figure out things exactly, but the exhaust velocity and initial/total mass make up significant portions of the equation, and increasing the former while decreasing the latter will make significant impact on the ability to leave a more massive planet.
