after man landed on the moon in 1969 , astronauts around the world had a problem-there were no other places they could go ! even today , the other planets are still too far away for astronauts to fly to . so , while rockets and robots can go to other planets , manned flights have to stay closer to home , for the time being . therefore , since visiting the moon , manned space programs have turned their attention to solving problems related to living and working in space .
currently , nasa’s [(美国)国家航空航天局] manned space exploration program focuses on the space shuttle program . nasa now operates three space shuttles , discovery , atlanatis , and endeavor . unfortunately , two of nasa’s shuttles , challenger and columbia , have been lost through accidents . seven astronauts died in each accident . since the beginning of the shuttle program , the shuttles have flown more than a hundred missions . these missions have included putting satellites into orbit , photographing the earth , studying space , conducting experiments related to working in space , and conducting with various manned space station in orbit .
throughout the short history of the exploration of space , several space stations have been put into orbit . the first manned space station was the soviet station salyut 1 , put into orbit in 1971 . later , in 1986 , the soviet union launched the mir space station . mir stayed in orbit until march 23 , 2001 , over that time , 104 astronauts visited the station to stay for various lengths of time . the person who has spent the longest in space so far is russion astronaut valeri polyakov . working as the doctor aboard the station , he lived on mir for 438 days without returning to earth . in total , polyakov worked aboard mir for 678 days before retiring .
today , astronauts from around the world are working together to complete the inernational space station(iss). the first part of this space station was launched in 1998 . nasa predicts the iss should be completed by 2011 . in the long run, it is hoped that the iss will be a place where people can live and work all year round .
那我再加10可以再帮我翻译一篇吗。。
追答你把另外一篇贴出来,比这个长的话要加15
追问你翻译的貌似有一点错误。。。Discovery Atlantis和Endeavor那是航天飞机的名称 发现号 亚特兰蒂斯号于奋进号、以及我主要要的是这几句后面的。这些我已经翻译完了、、、、
