A new chapter in space flight began this week in 1950 July with the launch of the first rocket from Cape Canaveral, Florida: the Bumper V-2. Shown above, the Bumper V-2 was an ambitious two-stage rocket program that topped a V-2 missile base with a WAC Corporal rocket. The upper stage was able to reach then-record altitudes of almost 400 kilometers, higher than even Space Shuttles once flew. Launched under the direction of the General Electric Company, the Bumper V-2 was used primarily for testing rocket systems and for research on the upper atmosphere. Bumper V-2 rockets carried small payloads that allowed them to measure attributes including air temperature and cosmic ray impacts. Seven years later, the Soviet Union launched Sputnik I and Sputnik II, the first satellites into Earth orbit. In response in 1958, the US created NASA.

📅 在1950年7月的一個重要週，太空飛行歷史新增了一個新篇章：第一枚火箭在佛羅里達州的卡納維拉爾角發射，即Bumper V-2。這枚Bumper V-2是個雄心勃勃的雙級火箭計劃，由V-2導彈基座和WAC Corporal火箭組成。上級火箭乃當時能夠抵達接近400公里的高度，甚至高於後來的太空梭。
💡 在通用電氣公司的指導下，Bumper V-2的主要用途是測試火箭系統及研究上層大氣。Bumper V-2火箭搭載的小型有效載荷可測量氣溫及宇宙射線影響等各種屬性。七年後，蘇聯成功發射了第一顆進入地球軌道的衛星——Sputnik I和Sputnik II。作為回應，美國在1958年成立了NASA.
