VOA慢速英语 登陆月球:双子星计划

　　VOICE TWO:

　　The first Gemini spacecraft would carry astronauts Virgil Grissom and John Young. Its Titan rocket could lift three times as much weight into space as the Atlas rocket used for the Mercury flights. The launch took place without a problem on March twenty-third, nineteen sixty-five.

　　Grissom and Young orbited the Earth only three times. But they did something that the Mercury astronauts had not been able to do. They changed their orbit while in space. The Gemini astronauts were developing the control that would be needed for a trip to the moon.

　　Less than two months later, James McDivitt and Ed White went into space on the second Gemini flight. Their flight included several experiments. But one seemed almost unbelievable -- a space walk.

　　Ed White would leave the protection of the spacecraft and move out into the unknown emptiness of space.
