Two astronauts are seated inside the Gemini spacecraft in this artist’s concept made in January 1965. The Gemini program was an early NASA human spaceflight program designed to bridge the Mercury and Apollo programs. Its main goal was to test equipment and mission procedures in Earth orbit and to train astronauts and ground crew for future Apollo missions. The first two Gemini missions were uncrewed; crew members flew on the 10 following missions.

这是一幅创作于1965年1月的艺术构想图，展示了两名宇航员坐在双子座飞船内部的场景。双子座计划是NASA早期的人类航天计划，旨在连接水星计划和阿波罗计划。其主要目标是在地球轨道上测试设备和任务程序，并为未来的阿波罗任务训练宇航员和地面团队。双子座的前两次任务是无人飞行，接下来的10次任务则由宇航员执行。
