  1. Hello, great eight.
  2. So this is a reading comprehension lesson.
  3. This is for the first part of the lesson, as
  4. you are going to perform your or to prepare to
  5. perform your first treat of the selection, which is 25
  6. years later, Hubble sees beyond trouble Start.
  7. Have you ever guys heard about Hubble?
  8. The telescope, the telescope?
  9. If yes, please let me know.
  10. What have you heard about it?
  11. What do you know about it?
  12. What have you seen about it?
  13. So in 25 years later, Hubble's is beyond trouble.
  14. Start Dennis over by recount the initial difficulties and remarks
  15. remarkable accomplishments of the Hubble Space Telescope.
  16. Launched into space in 1990 the telescope had initial technical
  17. problems that led to bird images being sent back to
  18. Earth. Three years later, um, a NASA crew spent five
  19. days in space repairing the telescope.
  20. The, uh, the Hubble began recording images of space that
  21. had never before been seen.
  22. Astronaut serving crews kept the Hubble up to date, but
  23. in 2000 and three, the Columbia space shuttle exploded.
  24. This led to this led NASA to cancel a scheduled
  25. stop of repair.
  26. The Hubble appeared to be doomed.
  27. But in 2000 and nine, at a pair of crew
  28. once again served at today, the Hubble continues to record
  29. extraordinary images of our universe.
  30. So you have to know that it excerpt that you're
  31. reading is published on April 2015 in New York Times.
  32. So if I ask you guys since it's taken from
  33. a newspaper, what is the genre of this selection?
  34. And remember, it's full of fact science.
  35. Yes, it is a science article.
  36. So who's the author?
  37. The author is Dennis over by.
  38. He was born in 1940 for 75 years old.
  39. Yeah, so he's a science writer.
  40. Specialist, Um, he's specialized in physics and cosmology.
  41. In 18 80 1998 he started working in The New
  42. York Times as science editor.
  43. Then he switched to full time writing, and he has
  44. been published in The New York Times, Science and Los
  45. Angeles Times.
  46. He lived in New York with his wife, daughter and
  47. two cats.
  48. Yeah, so about the text.
  49. 25 years later, Hubble's is beyond trouble.
  50. Start it is a science article.
  51. Against all odds.
  52. It's 25 years in space and, uh, accounting for the
  53. Hubble Space Telescope this month.
  54. Few icons of science have had such a risky extent.
  55. The telescope survived political storms, physical disasters and the simple
  56. passage of time in the service of cosmic exploration.
  57. This is, by the way, the image of the Hubble
  58. telescope. Okay, so in 1946 the astronomer Lyman Spitzer Jr
  59. had a dream.
  60. A telescope in space would be above the unruly atmosphere.
  61. It would be able to see the stars unaffected by
  62. the storms that blur them and make them twinkle.
  63. It would be able to see ultra violet, and infrared
  64. discharge is blocked by the atmosphere and invisible to astronomers
  65. on the ground.
  66. It took more than 30 years for the rest of
  67. the astronomy community, NASA and Congress to buy, uh, this
  68. dream. It was done as a way to showcase the
  69. abilities of the space shuttle, which was still being developed
  70. then, and the ability of astronaut to be able to
  71. work routinely in space.
  72. By the time the telescope was sent into space from
  73. the space shuttle Discovery on April 25 1992 had been
  74. almost canceled at least twice.
  75. It had also been delayed following the explosion of the
  76. shuttle Challenger in 8 1986 and one last thing when
  77. the Hubble was finally placed in space.
  78. NASA publicized publicized story, Um, were instantly at the top
  79. of their game.
  80. They hailed it as the greatest advance in astronomy since
  81. Galileo. And it might have been an excerpt.
  82. Sorry. Except for one problem.
  83. They couldn't focus the telescope.
  84. Happel had an 8 ft mirror designed using spy satellite
  85. technology. The mirror was just small enough to fit into
  86. the space shuttle cargo bay.
  87. Okay, guys, so we'll learn more about this selection in
  88. our next lesson.
  89. So, please, if you have any questions, don't hesitate to
  90. send me your question or to join my dropping session.
  91. Okay, that's all for today.
  92. Thank you, guys.
