“thurs day is the beginning of that journey,”Mark Geyer,Orion's program manager,said at a news conference on Tuesday。“Orion,which looks like a larger version of the cone-shaped Apollo capsule,Is sitting atop a delta iv heavy rocket at cape Canaveral air for“Orion”的形状和阿波罗升空时间定在本周四上午07点05分,太阳下山后即将开始。遇到险恶的天气,升天至少会延迟2小时39分钟。the rocket ' s second stage should push the 11-foot-long Orion into an elliptical orbit that reaches 3,600 miles above the earth 's(by contrast,The international space station is about 250 miles from earth。


)火箭的第二级在启动11英尺(3.35米)宽的猎户座(Orion)时,到达距地球表面约3600英里的椭圆轨道,Orion Will Then Re-enter the Earth ' s Atmosphere At 20,000 miles per hour,Clland temperatures on its heat shield will approach 4,000 degrees Fahrenheit。然后猎户座以每小时2万英里的速度新进入地球大气,这与宇宙飞船从月球回来的速度非常相似。猎户座隔热层的温度将与华氏4000度(约2200摄氏度)相似。

at The end of The four-And-a-half-hour flight,it will splash down in The Pacific ocean,about 600 miles off The coast of baast四个半小时的飞行结束后,“猎户座”没有坠入距加利福尼亚海岸约600英里的太平洋海域,美国海军两栖舰安克雷奇号(Anchorage)沉没后,用卡车运往佛罗里达的肯尼迪航天中心,拒绝仔细检查。The flight,estimated to cost $375 million,will provide a full-scale test of the performance of Orion ' s parachutes,hean With 1据估计,此次飞行花费了约3.75亿美元,使用1200个传感器记录数据,彻底测试猎户座降落伞、防水屋顶和其他系统的性能。“we expect it to go fine,but you really have to fly it to test it out,”Mr. geyer said while the capsule will not be carrying any people,it will be taking mementos and artifacts . they include a small sample of lunar soil,Part of其中还包括月球土壤样品的一部分、霸王龙化石的一部分、玛雅安吉洛的诗、古斯塔夫阿克希尔姆霍尔斯特《行星》协奏曲的火星部分录音。

NASA is pursuing the idea of capturing a small asteroid And taking it to the neighborhood of the moon,And aster下一个任务还不透明。NASA期待着猎杀小行星并将其带到月球附近,宇航员将乘坐猎户座飞往小行星。NASA官员回应说,该小行星重定向任务在支出范围内,可以推动最终登陆火星所需的技术发展。


some skeptics have questioned whether Orion,originally part of A program started under president George w . bush to send astronauts back to ISS“Orion”原本是将宇航员送回月球的计划的一部分,始于乔治W布什(George W. Bush)兼任美国总统期间。一些怀疑论者批评“Orion”是否存在不存在的合适性,这可能是浪费数十亿美元。the Obama administration canceled Orion and the entire moon program as too expensive and too far behind schedule . but many members of congress dis D因为费用太便宜,而且比计划超前。

但是国会的很多议员不同意停止它,所以NASA重新启动了“Orion”项目,将其用作国际空间站的救生艇,其设计与中断非常相似。NASA also started work on a heavy-lift rocket known as The Space Launch System that will carry Orion on future launching s . together,The rocketsome house Republicans have pushed to revive plans to return to the moon,but have not proposed funds to build a lander。
