| Mar 24, 2019 at 10:30 | comment | added | Diego Sánchez | Just for the record, it should be noted that Heinlein seemed to have a good understanding of orbital mechanics. Books he wrote as early as the 1940' describe maneuvers that sound reasonable, not the usual "shoot from earth to mars in a couple hours". | |
