NASA Studies Aerogel Fission Fragment Rocket 200X Better ISP Than Chemical
by Brian Wang from NextBigFuture.com on (#67SW2)
NASA NIAC phase 1 studies development of a nuclear fission fragment rocket engine (FFRE) that is exponentially more propellent efficient than rocket engines currently used to power today's space vehicles and could achieve very high specific impulse (>100,000 sec) at high power density (>kW/kg). Fission Fragment rockets are several proposed nuclear rocket designs made since ...
