1 00:00:00,000 --> 00:00:04,000 Well, first of all, the first evaluation 2 00:00:04,000 --> 00:00:08,000 Images came in in the middle of the night but the team all came in and 3 00:00:08,000 --> 00:00:12,000 gathered, and we evaluated whether 4 00:00:12,000 --> 00:00:16,000 The camera was working well enough for us to proceed on with the alignment and 5 00:00:16,000 --> 00:00:20,000 as we analyzed those first photos, if you will, 6 00:00:20,000 --> 00:00:24,000 the team was pretty positive that the camera was working properly 7 00:00:24,000 --> 00:00:28,000 and the instrument was working properly 8 00:00:28,000 --> 00:00:32,000 so we picked a star that was very bright and didn’t have any 9 00:00:32,000 --> 00:00:36,000 stars near it that would contaminate the image. We know that the primary mirror 10 00:00:36,000 --> 00:00:40,000 segments aren’t aligned so they actually act like 18 separate telescopes 11 00:00:40,000 --> 00:00:44,000 And we expect to see 18 separate images, one for each 12 00:00:44,000 --> 00:00:48,000 mirror, that are a little bit blurry at this point because we haven’t 13 00:00:48,000 --> 00:00:52,000 aligned or focused anything. So we pointed at a bright star 14 00:00:52,000 --> 00:00:56,000 and we made a mosaic. We actually took the Near Infrared camera and we 15 00:00:56,000 --> 00:01:00,000 took images in different parts of the sky and then we looked 16 00:01:00,000 --> 00:01:04,000 for the 18 spots from the 18 different telescopes, if you will. 17 00:01:04,000 --> 00:01:08,000 and we were very excited to find them. The 18 spots were actually 18 00:01:08,000 --> 00:01:12,000 fairly close to each other so, really everything was very close to what was 19 00:01:12,000 --> 00:01:16,000 predicted. We’ve identified which of the 18 spots 20 00:01:16,000 --> 00:01:20,000 is which mirror. At this point we even know which ones are from 21 00:01:20,000 --> 00:01:24,000 the wings. And turns out one of the wings, you can actually see those 3 spots 22 00:01:24,000 --> 00:01:28,000 are a little farther over, and that’s sort of what we expected 23 00:01:28,000 --> 00:01:32,000 so, we’ve identified all 18 spots and the next step 24 00:01:32,000 --> 00:01:36,000 is to make an array of them. And then we are ready to start what we call 25 00:01:36,000 --> 00:01:40,000 global alignment. Which is when each of those 18 spots will start to be 26 00:01:40,000 --> 00:01:44,000 aligned and focused. And that’s sort of last step 27 00:01:44,000 --> 00:01:48,000 before we take those 18 spots and put them on top of each other to start forming 28 00:01:48,000 --> 00:01:52,000 a single star going through the 18 separate telescopes 29 00:01:52,000 --> 00:01:56,000 that’s the work we’ll be starting soon. 30 00:01:56,000 --> 00:02:00,000 We also took a “selfie” of the primary mirror. We took 31 00:02:00,000 --> 00:02:04,000 an image of the primary mirror and that helps us understand the alignment 32 00:02:04,000 --> 00:02:08,000 of the telescope, especially the primary mirror to the camera 33 00:02:08,000 --> 00:02:12,000 itself and the instruments. There’s actually a special lens in the Near Infrared camera 34 00:02:12,000 --> 00:02:16,000 that you can put in and it allow you to take a picture of the primary mirror itself 35 00:02:16,000 --> 00:02:20,000 and in this particular case, one of the segments is pointing at a 36 00:02:20,000 --> 00:02:24,000 star. So that is the segment that lights up but, you can see the outline 37 00:02:24,000 --> 00:02:28,000 through the shadows of all 18 segments. And you also can 38 00:02:28,000 --> 00:02:32,000 see the outline of what’s inside of the instrument itself, and we can see 39 00:02:32,000 --> 00:02:36,000 how well the primary mirror and the telescope is aligned to the instrument 40 00:02:36,000 --> 00:02:40,000 and that gives us some initial confidence that the alignment looks good 41 00:02:40,000 --> 00:02:44,000 and that’s a good starting point for doing the alignment of the telescope. 42 00:02:44,000 --> 00:02:48,000 We have now gotten some data looking through focus 43 00:02:48,000 --> 00:02:52,000 and we’ve been able to see that we don’t see any surprises 44 00:02:52,000 --> 00:02:56,000 in the shapes of the mirrors that we are looking at. So far so good but we do have a long way to go. 45 00:02:56,000 --> 00:03:00,288 music
