發(fā)現(xiàn)號(hào)再次踏上回家之路英語(yǔ)美文
Discovery, seen here, roared safely back to Earth after a tense first shuttle flight since the 2003 Columbia disaster and its crew pleaded for support for future space travel (AFP)
Low clouds kept shuttle Discovery and its crew of seven from making their much-anticipated return to Earth, and NASA vowed to bring the spacecraft down Tuesday in Florida, California or possibly even New Mexico.
"We will attempt to land somewhere," flight director LeRoy Cain said after Monday morning"s two unsuccessful landing opportunities.
The delay disappointed the astronauts" families, who were waiting at Kennedy Space Center for their loved ones" return after nearly two stressful weeks in orbit.
Discovery"s astronauts woke up Monday evening to The Beatles "Good Day Sunshine" and were ready to get back home.
It is the first shuttle flight since Columbia"s catastrophic re-entry in 2003, and the mission experienced a series of problems that required emergency spacewalk repairs and constant engineering analysis.
More cloudy weather was expected at Kennedy Space Center on Tuesday with a chance of rain, but it remained NASA"s first choice for an early morning touchdown. Edwards Air Force Base in California"s Mojave Desert was the next choice, followed by the White Sands Missile Range in New Mexico, the absolute last resort.
NASA Administrator Michael Griffin insisted "there"s no agony" associated with the one-day delay in getting Discovery home. Like other space agency officials, he was waiting for "wheels stop" on the runway before even thinking about celebrating.
Come Tuesday, "We"re going to land one way or another, one place or another, and all we"re talking about is where," Griffin said.
NASA prefers landing shuttles at the same place where it launches them, to avoid the several days and estimated $1 million in ferrying the spacecraft atop a modified jumbo jet back from the West Coast.
Discovery had enough power and supplies to stay in orbit until Wednesday, but NASA was holding out that option only if a technical problem arose that needed time to be resolved.
During the mission, the biggest setback was the loss of a 1-pound chunk of foam insulation from the fuel tank during the July 26 launch, the same problem that ended up destroying Columbia. NASA suspended future shuttle flights just one day after Discovery took off.
低沉的云層阻礙了“發(fā)現(xiàn)”號(hào)航天飛機(jī)和機(jī)上七名工作人員預(yù)期的返航，美國(guó)宇航局(NASA)誓言要在本周二讓這架航天飛機(jī)重返地球，著陸地點(diǎn)可能在佛羅里達(dá)州、加利福尼亞州甚至是新墨西哥州。
“我們將嘗試找個(gè)地方著陸。”這次飛行任務(wù)的主管萊羅伊·凱恩在錯(cuò)過(guò)了周一早上的兩次降落機(jī)會(huì)后說(shuō)。
計(jì)劃的推遲讓宇航員的家屬們很失望，他們正在肯尼迪航天中心等待親人在近兩周艱苦的太空工作后能平安歸來(lái)。
周一晚上，“發(fā)現(xiàn)”號(hào)上的宇航員們被“披頭士”樂(lè)隊(duì)的《陽(yáng)光日安》喚醒，他們已經(jīng)做好了回家的準(zhǔn)備。
這是自2003年“哥倫比亞”號(hào)返回地球時(shí)發(fā)生慘劇以來(lái)美國(guó)的首次航天飛行，此次任務(wù)遭遇了一連串的麻煩，不得不進(jìn)行緊急太空行走以檢修故障，NASA一直在對(duì)故障原因展開(kāi)工程學(xué)分析。
本周二，肯尼迪航天中心的云層預(yù)計(jì)會(huì)加厚，還有可能下雨，但它仍是NASA首選的凌晨著陸場(chǎng)。位于加利福尼亞州莫哈韋沙漠的.愛(ài)德華茲空軍基地是次選，新墨西哥州的白沙導(dǎo)彈靶場(chǎng)則是最后一步棋。
美國(guó)宇航局局長(zhǎng)麥克爾·格里芬堅(jiān)持認(rèn)為，發(fā)現(xiàn)號(hào)推遲一天回家“并不令人懊惱”。和其他宇航局官員一樣，他在等待“發(fā)現(xiàn)”號(hào)的輪子在跑道上“停止滑動(dòng)”的那一刻的到來(lái)，至于慶祝活動(dòng)他壓根還沒(méi)想。
“我們無(wú)論如何都要讓航天飛機(jī)著陸，我們一直在討論的就是在哪里降落，”格里芬周二說(shuō)。
NASA傾向于讓航天飛機(jī)在原來(lái)的發(fā)射場(chǎng)著陸，因?yàn)檫@樣可以不用花幾天時(shí)間把航天飛機(jī)放在一架改裝過(guò)的巨型噴氣式飛機(jī)上從西海岸運(yùn)回，免去了大約100萬(wàn)美元的運(yùn)輸費(fèi)用。
“發(fā)現(xiàn)”號(hào)有足夠的能量和供給維持飛行到周三，但只有當(dāng)需費(fèi)時(shí)解決的技術(shù)問(wèn)題出現(xiàn)時(shí)，NASA才會(huì)考慮這種選擇。
在本次飛行任務(wù)中，最大的挫折無(wú)疑是在7月26日的發(fā)射過(guò)程中，飛機(jī)油箱掉落了一塊一磅重的泡沫隔熱材料，而當(dāng)年“哥倫比亞”號(hào)正是毀于同樣的問(wèn)題。于是在“發(fā)現(xiàn)”號(hào)起飛的后一天，NASA推遲了之后的航天飛行。
Vocabulary:
stressful : 充滿壓力的
touchdown: 著地，降落
jumbo jet: 大型噴氣式客機(jī)
