NASAの5億ドル相当の宇宙望遠鏡を救う緊急ミッションは失敗したとCNNが報告しています。LINK衛星はスウィフト望遠鏡の軌道を上げる作業を実行することができず、NASAはこの古い望遠鏡が今年年内に地球大気层で焼却される見込みだと発表しました。
LINK衛星は7月3日に打ち上げられましたが、数週間後に制御不能に陥りました。開発会社のKatalystが制御を取り戻すことができましたが、これによりスウィフトとの接近作業が1カ月遅れました。しかし、その遅延はミッションの阻止要因にはなりませんでした。
NASAのジェイダッド・アイザックマン局長は、「我々はこのミッションを挑み、迅速かつリスクを冒すことを望んだ。それは未来の衛星修復能力にとって重要な経験になるだろう」と述べています。LINK衛星は今後もスウィフトとの接近作業を行う予定ですが、救援ではなく実証実験となる見込みです。
「我々はLINKの接近試みから学びを重ね、それを次のミッションに活かすことができる」とアイザックマン局長は述べています。SWIFT望遠鏡は軌道修復が設計されていないため、今回の試みから得た教訓は将来的な衛星修理任務にも生かされる可能性があります。
Remember that rush rescue mission for NASA's $500M space telescope? It failed, reports CNN, and the LINK satellite won't be able to boost the telescope's orbit. NASA says its decades-old Swift telescope will now continue losing altitude, until it reaches Earth's atmosphere later this year and burns up.
CNN reports:
Just weeks after LINK lifted off on July 3, it started to spin out of control. [Satellite designer] Katalyst was able to regain control of the satellite, but the company acknowledged that the issue cost it time, which would delay LINK's rendezvous with Swift by about a month. However, that postponement — at least initially — did not seem to be a deterrent to the mission. Now, NASA and Katalyst have announced that LINK's mission will not capture and boost Swift to a higher orbit "due to ongoing attitude control issues," according to statements Wednesday.
"NASA should be willing to move quickly and take smart risks when the potential return is worth it, and that is exactly what we did with this mission," NASA Administrator Jared Isaacman said in a statement. "This is not the outcome we were working toward, but it does not change why this mission was worth attempting. The team moved with extraordinary speed to give Swift a chance to carry out more science while advancing capabilities America will need for satellite servicing in the future...."
The mission team is forging ahead with its plan for LINK to rendezvous with Swift — but as a demonstration rather than a rescue. "We are going to learn everything we can from LINK's rendezvous attempt and put those lessons to work on the missions that follow," Isaacman said... Swift wasn't designed to be serviced in space, which means that insights from the demonstration could be used for future missions... "We have already learned a tremendous amount," [said Ghonhee Lee, CEO of Katalyst Space Technologies], "and now our job is to turn those lessons into something durable — building a repeatable playbook to inform future rendezvous and proximity operations and satellite servicing."
