Nuclear rockets in space (from a succession of small U-235 detonations) pose no danger to earthlings if emissions are far from earth, and space is mostly radiation anyway. So it will be like adding a teaspoon to a potentially infinitely large ocean. A small experiment can be conducted with a manless small rotary rocket or artificial satellite, where radius of four armatures, similar to WoLaSP, very short, each having bulbs at the end receiving a conveyer belt of small enriched U-235 capsules, triggered each by each of four neutron-guns in center of satellite. Detonations can occur when close to sun by space-time warpage as a result of inertia sensing and/or remote control, where approximate speed, linear, and circular because of the predetermined velocity of the nuclear rockets, combining initial linear speed from earth ejection, central force of sun speeding up satellite, moment of inertia from spin, and the presumed added Woodward effect, capitalizing on linear/circular inertia and general relativity, will call for remote sensing of new transverse speeds to help enhance or debunk the Woodward theory.
According to Woodward, there is a transient mass fluctuation, and mass “loss” may be thought of as high energy gain, whether you use his mass coupling in his lab, where there is a dialectric of the capacitor under the influence of varying electromotive forces, or an oscillating satellites (Woodward may have chosen linear oscillation, as circular motion and the torque it produces in the transverse direction is hard to calculate precisely with a margin of error that makes the presumed Woodward effect hard to calculate).
