In this elegantly simple machine, a flow of supersonic air from the missile’s flight passes through a nuclear reactor core and is heated to ferocious temperatures.
Fancy-pants advances in rocket propulsion may usher in a new era of spaceflight
Chemical rockets, solar sails, and electric propulsion could help spaceships travel further and more efficiently than ever before. An independent news and commentary website produced by academics and journalists. An independent news and commentary website produced by academics and journalists.
The US Defense Advanced Research Projects Agency (Darpa) has recently commissioned three private companies, Blue Origin, Lockheed Martin and General Atomics, to develop nuclear fission thermal rockets for use in lunar orbit.
Such a development, if flown, could usher in a new era of spaceflight. That said, it is only one of several exciting avenues in rocket propulsion. Here are some others.

Chemical rockets
The standard means of propulsion for spacecraft uses chemical rockets. There are two main types: solid fuelled (such as the solid rocket boosters on the Space Shuttle), and liquid fuelled (such as the Saturn V).
In both cases, a chemical reaction is employed to produce a very hot, highly pressurised gas inside a combustion chamber. The engine nozzle provides the only outlet for this gas which consequently expands out of it, providing thrust.
