RE: We are relying on ancient rocket engine designs to shoot us into space! Is the Aerospike engine an alternative?

Of course not, since the prototype was cancelled before being fully built. I really hope that as the private sector wins some of the pie slice of the market, it will develop their own ideas and fund them without the problems coming from the political agendas of various administrations.
Just as the Pharma sector did, as soon as they had a steady profit they started having their own research.
Thanks for dropping by, I know you were impressed by NASA-Johnson.
