Oberth analyzed the problems of rocket technology as well as the physiological problems of space travel, and his writings encouraged many other enthusiasts and researchers. In 1928, Oberth and others were consultants for a German film about space travel called The Girl in the Moon. The script included the now-famous reverse countdown before ignition and lifloff. As part of the publicity for the movie, Oberth and his staff planned to build a small rocket and launch it. The rocket was only static-fired and never launched, but the experience was a stimulating one for the work crew, including an 18-year-old student named Wernher von Braun.

Researchinto heat physics helped lay the foundations for better engine designs, and advances in metallurgy stimulatecl new standards for tanks, plumbing, and machining to withstand high pressures, heat, and the super-cold temperatures of liquefied gases. Progress in mathematics, navigational theory, and control mechanisms made successtul guidance systems possible. Although "I'siolkovsky did not construct any working rockets, his numerous essays and books helped point the way to practical and successful space travel.

Boosted by a modified Atlas ICBM, Friendship 7 lifted off from Cape Canaveral on 20 February 1962 and orbited the Earth three times before Glenn rode the capsule to splashdown and recovery in the Atlantic. At the Marshall Space Flight Center (left), Dr. Wernher yon Braun isflanked by the seven original astronauts as he explains details of rocket fabrication.
