“The SpaceX team had previously shown that they could develop new hardware in one-third the time at one-tenth the cost as the mainline aerospace companies. Now they have done something that the majors have never been able to do. And not just anything, but the single most important step towards inexpensive space launch - controlled recovery of the launch vehicle first stage. The competition had better wake up because they've just been 'Sputniked'. Chapeau!,” said Mars Society President Dr. Robert Zubrin.
