@WholeMarsBlog @NASASpaceflight @BBCAmos There is a reason no fully reusable orbital rocket has been built – it’s an insanely hard problem. Moreover, it must be rapidly & completely reusable (like an airplane). This is the only way to make life multiplanetary. Efficiencies of scale is why Starship is so large. — PolitiTweet.org
