SUMMARY: Although NASA engineers are working on radical new kinds of propulsion, like ion engines, nuclear rockets, and even solar sails, they're still tuning up the old standby liquid-fueled rocket. Current rockets burn a small amount of fuel into preburners which power pumps that force the rest of the fuel into the combustion chamber. A new strategy will be to run all the fuel through the preburners which will create higher pressures, and should give better performance from the rocket.

Funding engineering iterations is an excellent thing for a public agency to do. It isn't Science and that is what I like about this. It IS engineering.

So the old rocket concept is far form being exhausted ! We see many innovations these days , piston pomp rocket, New pressure fed rocket , vortex rocket , rubber hybrid rocket , vax hybrid rocket .... I hope some of these will give us the cheap acces to LEO we need.

They have to be tested on something that flies for that. 8)
Few researchers risk their babies that way.
I appreciate the engineering iterations, but unless these things fly I look on them as job programs for researchers. We have to fund flights too and bias for those researchers willing to take that final step.
