Nuclear Rockets and Project Breakthrough Starshot.
"Modular Assembled Radiators for Nuclear Electric Propulsion Vehicles, or MARVL, aims to take a critical element of nuclear electric propulsion, its heat dissipation system, and divide it into smaller components that can be assembled robotically and autonomously in space. This is an artist’s rendering of what the fully assembled system might look like. NASA/Tim Marvel" (NASA,Nuclear Electric Propulsion Technology Could Make Missions to Mars Faster) Nuclear rockets can have football-field-size heat conductors to control the thermal effect of a nuclear reactor. The new nuclear systems can journey to Mars faster than regular chemical rockets. The problem with nuclear thermal engines is the heat of the system. Nuclear reactors can transfer their thermal energy to water. Then, water transports heat to the larger water systems like lakes. In space nuclear reactors must shine that thermal energy to space. In the NASA construction reactor, the football-field size element conducts th...
