SpaceX had a huge and long runway, took over from ex-NASA guys who worked on the Shuttle. Thrust vectoring and other key technologies already had been developed in similar companies. John Carmack's Armadillo Aerospace worked in the space. Carbon capture is not exactly picking up where the Shuttle left off. The most interesting part of carbon capture is the offshoot technologies.
