The first Space Shuttle did n’t reach sphere until 1981 , but NASA was working on pattern for well-nigh a twelve years before that . And wait at the progression of these concept drawings , you could see how via media were made and budgets were cut . Here ’s the evolution of the Space Shuttle , in icon .

NASA ’s Spacecraft Design Division ( SDD ) began serious work on developing concepts for the Space Shuttle in early 1970 . The drawings below illustrate most of the configurations that were view , in more or less chronological order . ( The first identification number accompanying each design is the series number , followed by the date of the intention . ) What ’s astonishing is the speediness with which design changes were made , with many being made each week .
I ’ve sometimes thought that this serial could be animated , so one could keep an eye on the birdie become both more compromised and more complex as it evolve and budgets were cut . What ’s kind of sad is seeing what a totally cool spaceship the shuttle might have been .
One of the first major intention change was from square - wing ( to begin with proposed by Mercury spacecraft designer Max Faget ) to delta - offstage . This occurred with Orbiter 022B in May 1971 . The other major modification that affected the final plan of the bird was the decision to desolate a pilot , reusable , fly - back booster — which had been an integral part of Space Shuttle design from the commencement — in favour of spendable outside armored combat vehicle and reusable strap - on boosters . This occurred with Orbiter 026 , also in May 1971 . After this , SDD technologist focalize on parallel - burn feeler , in which the bird ’s main locomotive engine are open fire at the same time as the takeoff rocket ’s . These design most often contract the course of sequential , staging or stage - and - a - half designs .
Shuttle 040C usher in the now - conversant outside fuel tank flanked by a pair of substantial - fuel boosters . The only significant differences between 040C and the bird design that was eventually flown were that the unanimous - fuel boosters were attached to points close to the shuttle — between the international armoured combat vehicle and the shuttle ’s wing — and that the external tank was outfitted with bombastic wings . In March 1973 , NASA committed to the parallel - burn configuration .
