ハッブル宇宙望遠鏡はあと7〜8年で落ちてくる？NASAが会社に「救う方法」を募集
Hubble Is Sinking, and NASA Wants Help
1NASA has asked private companies for ideas on how to keep the Hubble Space Telescope working or safely end its mission. The space agency issued a request for information on October 29 and announced it the next day.
2Hubble was launched in 1990. It has been operating for more than 35 years. However, it is gradually losing altitude because of drag from the atmosphere. The telescope has no propulsion system, which means it cannot raise its own orbit. NASA works with the European Space Agency on Hubble, and NASA's Goddard Space Flight Center in Maryland manages the telescope.
3NASA's analysis predicts that Hubble will probably fall back into the atmosphere in 2033 or 2034. The agency expects that a mission would have to fly by 2032.
4NASA is looking at three options. A visiting spacecraft could boost Hubble higher, which would give it more years of science. It could also service the telescope to improve what it can do. The third option is a controlled reentry or another safe way to dispose of it in orbit once its science work is over.
5NASA Administrator Jared Isaacman said Hubble can still do important science and that the agency should look at every reasonable chance to keep it running. Nicky Fox, who leads NASA's science missions, said the agency is eager to look at many possible ways to lift Hubble into a higher orbit before it reenters. Companies have until 3 p.m. Eastern time on November 30 to send their answers.

全文訳
1NASAは民間の会社に、ハッブル宇宙望遠鏡を動かし続ける方法、あるいはその任務を安全に終わらせる方法について、アイデアを求めました。NASAは10月29日に情報提供の依頼を出し、次の日にそれを発表しました。
2ハッブルは1990年に打ち上げられました。それから35年以上、働き続けています。しかし、大気の抵抗のために、少しずつ高度が下がっています。望遠鏡には推進装置が無く、そのため自分で軌道を上げることができません。NASAはハッブルについてヨーロッパ宇宙機関（ESA）と協力していて、メリーランド州にあるNASAのゴダード宇宙飛行センターが望遠鏡を管理しています。
3NASAの分析では、ハッブルは2033年か2034年に大気の中へ落ちてくる可能性が高いと予測されています。NASAは、ミッションは2032年までに飛ばなければならないと見ています。
4NASAは3つの選択肢を考えています。訪れた宇宙船がハッブルをもっと高く押し上げれば、科学の観測を続けられる年数がのびます。また、望遠鏡を整備して、できることを増やすこともできます。3つ目の選択肢は、科学の仕事が終わったら、制御された再突入か、軌道上で安全に処分する別の方法をとることです。
5NASAのジャレッド・アイザックマン長官は、ハッブルにはまだ大事な科学の仕事が残っていて、動かし続けるためのあらゆる現実的な機会を検討すべきだと述べました。NASAの科学ミッションを率いるニッキー・フォックスさんは、再突入の前に、ハッブルをもっと高い軌道へ押し上げるいろいろな方法を探りたいと述べました。会社は、アメリカ東部時間の11月30日午後3時までに答えを送ることになっています。
文法ポイント：関係代名詞 which（前の文全体を受ける）
「, which ～」が、前の名詞ではなく前の内容全体を受けて「そしてそのことは～」と説明を足す。本文の The telescope has no propulsion system, which means it cannot raise its own orbit. は「望遠鏡には推進装置が無く、そのこと（推進装置が無いこと）は、自分で軌道を上げられないことを意味する」。
