1970 in spaceflight 1970 in spaceflight Japan and China each launched their first satellites in 1970, bringing the total number of nations with independent launch capability to five. Apollo 13 was launched; after suffering an explosion in deep space it had to circumnavigate the moon and use the LM as a life boat. Apollo 13 was a successful disaster in which the crew survived. The Soviet space program continued its Luna program with Luna 17, which delivered the robotic Lunokhod 1 rover to the lunar surface, and Luna 16, which achieved the first unmanned lunar sample return. The Soviets also continued the success
Apollo program stages, carrying dummy upper stages filled with water. The first flight with a live S-IV was launched from LC-37. This was followed by five launches of boilerplate CSMs (designated AS-101 through AS-105) into orbit in 1964 and 1965. The last three of these further supported the Apollo program by also carrying Pegasus satellites, which verified the safety of the translunar environment by measuring the frequency and severity of micrometeorite impacts. In September 1962, NASA planned to launch four manned CSM flights on the Saturn I from late 1965 through 1966, concurrent with Project Gemini. The payload capacity would have severely
