This illustrated documentary follows the tiny shape error behind the telescope\u2019s first blur and the mission that corrected the light where the instruments could use it.During five spacewalks, astronauts installed WFPC2, which corrected its own images, and COSTAR, which redirected corrected light to selected earlier instruments. The crew also replaced gyroscopes and solar hardware. Follow the diagnosis and mission planning, the first sharp WFPC2 image, a separate COSTAR-dependent test, and the months of checks that verified the repaired observatory\u2019s systems.The story then turns to Hubble\u2019s later servicing missions and the serviceable design that let new instruments and renewed systems extend the observatory\u2019s usefulness long after launch. The credited NASA\/STScI M100 comparison appears only as a factual insert inside the film; it is not a controlled optical test.Chapters:00:00 The blur01:48 What Hubble was built to do04:32 One mirror, several foci08:04 Finding the cause and designing the repair12:46 STS-61: five spacewalks21:55 The first sharp return25:57 A repair becomes a program28:35 The answerSources and further reading:NASA \u2014 A Brief History of the Hubble Space Telescope: https:\/\/www.nasa.gov\/history\/hubble\/NASA Science \u2014 Servicing Mission 1: https:\/\/science.nasa.gov\/mission\/hubble\/observatory\/missions-to-hubble\/servicing-mission-1\/NASA Science \u2014 Hubble Servicing Missions Timeline: https:\/\/science.nasa.gov\/mission\/hubble\/overview\/hubble-timeline\/hubble-servicing-missions-timeline-full-text\/NASA Technical Reports Server \u2014 Hubble Space Telescope: First Servicing Mission (1994): https:\/\/ntrs.nasa.gov\/archive\/nasa\/casi.ntrs.nasa.gov\/20060049142.pdfNASA Technical Reports Server \u2014 Hubble Space Telescope Optical Systems Failure Report (1990): https:\/\/ntrs.nasa.gov\/search.jsp?R=19910003124NASA Science \u2014 The History of Hubble: https:\/\/science.nasa.gov\/mission\/hubble\/overview\/the-history-of-hubble\/NASA Science \u2014 Hubble History Timeline: https:\/\/science.nasa.gov\/mission\/hubble\/overview\/hubble-timeline\/hubble-history-timeline-full-text\/NASA Science \u2014 Hubble\u2019s Mirror Flaw: https:\/\/science.nasa.gov\/mission\/hubble\/observatory\/design\/optics\/hubbles-mirror-flaw\/NASA \/ STScI \u2014 M100 old\/new optics comparison: https:\/\/science.nasa.gov\/asset\/hubble\/pictures-of-galaxy-m100-with-hubbles-old-and-new-optics\/YouTube release scheduled for October 31 at 2:00 AM Toronto: https:\/\/youtu.be\/ne-uU5S3fCYCredits:GreenSpacealienOriginal research and scriptArchive insert: NASA, STScI (M100 old\/new optics comparison)Full sources and credits accompany this video.Find us on:Facebook: https:\/\/www.facebook.com\/profile.php?id=61594406836899Instagram: https:\/\/www.instagram.com\/greenbigspacealien15\/X: https:\/\/x.com\/GreenSpacealieTikTok: https:\/\/www.tiktok.com\/@greenbigspace15Reddit: https:\/\/www.reddit.com\/r\/GreenSpacealien15\/Dailymotion: https:\/\/www.dailymotion.com\/user\/gree","author_name":"Green Space","author_url":"https:\/\/www.dailymotion.com\/green.hbw590","width":480,"height":269,"html":"<iframe frameborder=\"0\" width=\"480\" height=\"269\" src=\"https:\/\/geo.dailymotion.com\/player.html?video=xbs8kp2&\" allowfullscreen allow=\"autoplay; fullscreen; picture-in-picture; web-share\"><\/iframe>","thumbnail_url":"https:\/\/s2.dmcdn.net\/v\/gUCB61gvSypeDtmgN\/x720","thumbnail_width":1281,"thumbnail_height":720}
