Later that year, nineteen sixty-five, the United States tried to have one spacecraft get very close to another spacecraft while in orbit.
This was the first step in getting spacecraft to link, or dock, together.
Docking would be necessary to land men on the moon.
The plan called for a Gemini spacecraft carrying two astronauts to get close to an unmanned satellite.
The attempt failed. The target satellite exploded as it separated from its main rocket. America's space agency decided to move forward. It would launch the next in its Gemini series. Then someone had an idea: why not launch both Geminis. The second one could chase the first one, instead of a satellite. Again, things did not go as planned. It took two tries to launch the second Gemini. By that time, the first one had been in orbit about eleven days. Time was running out. The astronauts on the second Gemini moved their spacecraft into higher orbits. They got closer and closer to the Gemini ahead of them. They needed to get within six hundred meters to be considered successful. After all the problems on the ground, the events in space went smoothly. The two spacecraft got within one-third of a meter of each other. The astronauts had made the operation seem easy. In January, nineteen fifty-nine, the Soviets launched a series of unmanned Luna rockets. The third of these flights took pictures of the far side of the moon. This was the side no one on Earth had ever seen. The United States planned to explore the moon with its unmanned Ranger spacecraft. There were a number of failures before Ranger Seven took pictures of the moon. These pictures were made from a distance. The world did not get pictures from the surface of the moon until the Soviet Luna nine landed there in February, nineteen sixty-six. 【続く】
