RRX Aerospace is conducting preliminary research into next generation performance analysis.

Changing social and political goals it seems will form the context for next generation aerospace development, in the coming decades.

One of the most obvious changes might be a shift to green fuel systems for an increasing number of vertical launch missions, to avoid potential long term damage to the planetary atmosphere, from residual pollutant buildup.

An efficient, clean burning green fuel system based glide down re-entry booster structure, might be possible with novel materials and enhanced control systems.
