The "fa­ther" was soon out­grown

Science Illustrated - - SPACE -

The V-2 was the first space rocket with liq­uid fuel, turbo pumps, and aero­dy­nam­ics which could han­dle su­per­sonic speeds. All the new in­ven­tions were also used in the next gen­er­a­tions of space rock­ets, which grew much larger than the V-2. In or­der to be able to lift still more cargo, ex­tra rocket stages with de­tach­able en­gines and fuel tanks were added, mak­ing the rock­ets grow. The V-2 was 14 m tall, whereas the gi­ant of the fu­ture, the ITS, will mea­sure no less than 122 m.
