自美国先后发生“挑战者”号和“哥伦比亚”号航天飞机爆炸事件之后,航天器的安全性就一直是关系世界航天事业发展的一个重要因素。正在设计中的美国新一代航天器“猎户座”载人探测飞船最大的特点之一就是安全性较现在的航天飞机提高了10倍,如果飞船在发射过程中发生意外,地面计算机自动系统可以使宇航员乘坐的载人太空舱自动弹离飞船主体,从而大大增强宇航员生存的机会。按目前的计划,总价值达5亿美元的“猎户座”载人探测飞船将于2013年进行试飞。
Since the United States’ “Challenger” and “Columbia” bombings in succession, the safety of spacecraft has been an important factor in the development of the world aerospace industry. One of the most prominent features of the new generation of U.S. spacecraft under investigation, “Orion”, is that it is 10 times more secure than today’s space shuttle. If the spacecraft is in an accidental launch, the ground computer automated system can Astronauts to take the manned spacecraft automatically fly off the main body of the spacecraft, thus greatly enhancing the astronaut survival opportunities. According to the current plan, the “Orion” manned exploration spacecraft worth a total of 500 million U.S. dollars will be tested in 2013.
