When the hardware is in place, pilots have been selected, and it feels like it just couldn’t happen in its time? The solution in the Air Force’s hands was the piloted spaceplane that resembled too much of a later generation spacecraft item, Dyna-Soar (X-20). Even before the days of the Space Shuttle, engineers were working on the design of a reusable space vehicle that would take off via rocket launch only to glide down onto a runway when it returned from space, as opposed to parachute down into the ocean. Armstrong was among the seven selected astronauts in April 1960, and wasn’t even close to becoming an Apollo 11 astronaut until years later.
Dyna-Soar was not simply a place that was somewhat steerable on the way back to Earth. A compact vehicle, with a delta wing design, using controlled re-entry, high heating loads and aircraft style recovery. For the aircraft to be used for reconnaissance or other missions, the design specified a single pilot, an equipment bay, and an optional retractable landing skid rather than wheels since normal tires would not be able to withstand reentry temperature. Early in 1961, changes and changes of changes in the booster were repeated, slowing the progress, until a selection was made in late 1961 to use Titan III as the launch vehicle. The root issue was just easier and more destructive.
Dyna-Soar had to serve as a variety of things: a research vehicle, a reconnaissance platform, a rescue vehicle, a satellite inspector and even a possible strike system. You can see what adds interest and makes the programme vulnerable at the same time. Secretary of Defense Robert McNamara decided that the Air Force had been too focused on controlled reentry and needed proffer any good explanation for what the vehicle would do in orbit. The program was cancelled, despite the fact that spacecraft construction had started and first flight plans were scheduled, on Dec. 10, 1963.
While the cancellation often is remembered as a Historical Near Miss, it is more important because of what did survive. The hypersonic flight research, thermal protection and reentry handling did not deteriorate, and neither did the work on the reentry program. Indeed, Air Force historical research reveals that the first test plan for Dyna-Soar even called for B-52 drop tests and Little Joe II suborbital flights, also at an affordable price to be flown in between captive testing and the complete launch of the Titan III. It was not taken, but back then it demonstrated just how much further the vehicle had got towards becoming a viable flight programme than just another paper exercise.
It is easier to see, today, than in 1963: its modern echo. The X-37B’s first mission alone brought more than 4,208 days of flight, making the old reusable-spaceplane concept the new testbed for the military. Carries experiments related to navigation, materials, power transmission, and orbital operations is carried then and launched via conventional rockets, and remains in orbit for months or years until it returns to a runway. Little is available for public release, but the way it operated would not have come as a surprise to Dyna-Soar planners.
That is one of the many reasons the X-20 is more than a throwback. It revealed an existing conflict in the development of flight beautiful space products require a long-life mission, and when a mission gets clearly defined, the previous architecture, as it were, springs into existence again. In 1963 the Air Force scrapped a winged orbital vehicle program during this time, NASA developed a much larger winged orbital vehicle, and finally, today uncrewed spaceplanes are a viable idea because they eliminated the toughest aspect of the original concept: a human aboard. The mission set Dyna-Soar toward never really went away, even in the case of the Chinese reusable robotic spaceplane project. Simply needed technology, doctrine, and patience to catch up.
