Stoke Space has set out to build a fully recoverable rocket, and they've started with the second stage, since recovering the first stage booster now looks like the easy part. With a team of veteran engineers from other launch companies Stoke took a relatively small investment and turned it into a fully working ground test vehicle, using hydrogen expander cycle to power the engine fuel pumps AND to flow hydrogen through the heat shield to keep it cool during reentry.
