欧洲“赫尔墨斯”号航天飞机将携带一套助推器火箭,以使乘员在起飞失败时能被弹离主火箭,使乘员能得以救生。这是在“挑战者”号航天飞机爆炸事故后,人们审查“赫尔墨斯”号的安全问题时做出的新决定。这些助推器将装在“赫尔墨斯”号航天飞机和“阿里安”火箭之间。
The European Hermes shuttle will carry a booster rocket to allow occupants to save lives by allowing their occupants to fly off the main rockets in the event of a take-off failure. This is a new decision taken by people to review the safety issue of the Hermes after the space shuttle Challenger space shuttle accident. These boosters will be mounted between the space shuttle Hermes and the Arian rockets.
