The next generation of the Rocket Engines

All rocket engines burn their fuel to generate thrust . If any other engine can generate enough thrust, that can also be used as a rocket engine

There are a lot of plans for new engines that the NASA scientists are still working with. One of them is the “ Xenon ion Engine”. This engine accelerate ions or atomic particles to extremely high speeds to create thrust more efficiently. NASA's Deep Space-1 spacecraft will be the first to use ion engines for propulsion.

There are some alternative solutions like Nuclear thermal rocket engines, Solar thermal rockets, the electric rocket etc.

We are looking forward that in the near future there will be some good technology to take us into space
