designed to be serviced and upgraded with time. 110 00:12:49.667 --> 00:12:54.734 Its overall mission period will be 20 years. 111 00:12:54.734 --> 00:12:58.000 Present, we were planning that the mission will end in 2010. 112 00:12:58.000 --> 00:13:00.834 Each time we fly the Hubble, we leave it a far better 113 00:13:00.834 --> 00:13:04.400 and more capable observatory than it was before, 114 00:13:04.400 --> 00:13:07.901 and in fact, during our final servicing mission 115 00:13:07.901 --> 00:13:10.868 currently planned for 2003, 116 00:13:10.868 --> 00:13:14.300 we will install a final set of two instruments on Hubble, 117 00:13:14.300 --> 00:13:16.701 and at that point, it will be at the very peak of its power. 118 00:13:16.701 --> 00:13:19.000 It will be better than it ever has been, 119 00:13:19.000 --> 00:13:20.767 so, no, it's not getting old. 120 00:13:20.767 --> 00:13:22.367 It's getting better. 121 00:13:27.367 --> 00:13:31.367 One of the things we found out in 1997 about Hubble 122 00:13:31.367 --> 00:13:35.868 was that the very thinnest exterior layer of its skin 123 00:13:35.868 --> 00:13:38.334 was showing the effects of aging from being in space 124 00:13:38.334 --> 00:13:40.033 for this long a period of time, 125 00:13:40.033 --> 00:13:42.400 and it was showing some blemishes and cracks, 126 00:13:42.400 --> 00:13:44.734 and this has had no effect 127 00:13:44.734 --> 00:13:46.968 on the performance of the telescope to date, 128 00:13:46.968 --> 00:13:50.634 but just to make sure that the thermal system of the telescope 129 00:13:50.634 --> 00:13:51.767 continues to work properly, 130 00:13:51.767 --> 00:13:53.834 that it stays at a uniform temperature, 131 00:13:53.834 --> 00:13:55.567 doesn't get too hot and too cold, 132 00:13:55.567 --> 00:13:57.767 we thought it was a prudent thing to do to go up 133 00:13:57.767 --> 00:14:01.334 and put some covers over these cracked areas 134 00:14:01.334 --> 00:14:03.701 so that they wouldn't get worse with time, 135 00:14:03.701 --> 00:14:05.667 so basically, we have big rolls 136 00:14:05.667 --> 00:14:09.067 of what will look like shiny wallpaper 137 00:14:09.067 --> 00:14:12.367 that you'll see the astronauts installing on the telescope, 138 00:14:12.367 --> 00:14:17.300 and other kinds of sheets will be placed in appropriate places 139 00:14:17.300 --> 00:14:20.133 with something that's analogous to a bottle stopper, 140 00:14:20.133 --> 00:14:22.667 for example, to fasten them on the telescope. 141 00:14:29.100 --> 00:14:32.300 Hubble science is very valuable and very important, 142 00:14:32.300 --> 00:14:36.634 and, yes, this extra mission is costing a big extra for NASA, 143 00:14:36.634 --> 00:14:38.534 but it's well worth the investment 144 00:14:38.534 --> 00:14:40.234 to keep Hubble science running. 145 00:14:57.467 --> 00:15:00.467 -Well, many of you have seen the really beautiful pictures 146 00:15:00.467 --> 00:15:04.200 that Hubble has sent back of stars and galaxies 147 00:15:04.200 --> 00:15:07.767 and deep pictures into deep space with long exposures, 148 00:15:07.767 --> 00:15:09.801 and the only way that Hubble can do this 149 00:15:09.801 --> 00:15:14.000 is if the gyros are working and holding the telescope steady 150 00:15:14.000 --> 00:15:17.200 so the motion doesn't cause shaking of the image, 151 00:15:17.200 --> 00:15:20.567 and so those gyros are there to hold HST, 152 00:15:20.567 --> 00:15:22.133 to hold Hubble steady. 153 00:15:28.400 --> 00:15:31.400 We didn't change the gyros in Servicing Mission 2 154 00:15:31.400 --> 00:15:33.100 because they were all operational, 155 00:15:33.100 --> 00:15:36.033 and we had no better or improved gyros on the ground 156 00:15:36.033 --> 00:15:38.133 to be able to replace it, 157 00:15:38.133 --> 00:15:42.267 so we felt that given their nominal 4-to-6-year life 158 00:15:42.267 --> 00:15:45.300 that these gyros would last 159 00:15:45.300 --> 00:15:47.868 until the next servicing mission, 160 00:15:47.868 --> 00:15:49.234 which was scheduled for about now, 161 00:15:49.234 --> 00:15:52.534 and in fact, those gyros have lasted, 162 00:15:52.534 --> 00:15:55.834 and the evidence is, Hubble is still doing science. 163 00:15:55.834 --> 00:16:01.100 Now, we did know that the wires that carry the current 164 00:16:01.100 --> 00:16:06.167 into the gyro motors were being corroded and weakened, 165 00:16:06.167 --> 00:16:08.534 and yet we couldn't predict 166 00:16:08.534 --> 00:16:10.334 when those wires might fall, so -- 167 00:16:10.334 --> 00:16:14.434 fail, so we had no reason to change out gyros then. 168 00:16:14.434 --> 00:16:17.567 The wires have failed, and we'll now be changing 169 00:16:17.567 --> 00:16:20.300 all of the gyros in the upcoming mission, 170 00:16:20.300 --> 00:16:24.033 and that should restore the redundancy for all of the gyros 171 00:16:24.033 --> 00:16:27.400 and will readily take us into the last servicing mission 172 00:16:27.400 --> 00:16:30.567 where we'll replace all six of the gyros again. 173 00:16:36.400 --> 00:16:39.367 The servicing missions are not routine. 174 00:16:39.367 --> 00:16:42.167 Each time we do these things, we do them, many of the things, 175 00:16:42.167 --> 00:16:48.400 the first time, and we practice, but this is very complex. 176 00:16:48.400 --> 00:16:50.434 Working in space is difficult. 177 00:16:50.434 --> 00:16:52.367 It takes a very large team, 178 00:16:52.367 --> 00:16:55.534 and we never know when we're liable to run into a problem. 179 00:16:55.534 --> 00:17:00.200 We train just rigorously to be able to solve problems. 180 00:17:00.200 --> 00:17:03.300 We have pages and books of books of contingencies. 181 00:17:03.300 --> 00:17:05.400 We work really closely with the astronauts 182 00:17:05.400 --> 00:17:07.767 to work on contingencies. 183 00:17:07.767 --> 00:17:09.100 Some of the things we've done before, 184 00:17:09.100 --> 00:17:11.033 the Fine Guidance Sensors we've changed before, 185 00:17:11.033 --> 00:17:13.300 and so we're confident we can do that 186 00:17:13.300 --> 00:17:14.567 but then just like at home, 187 00:17:14.567 --> 00:17:16.667 you never know when you bend a pin, 188 00:17:16.667 --> 00:17:18.133 or the plug doesn't quite fit, 189 00:17:18.133 --> 00:17:22.100 and you need to stop and squeeze the plug, so you need to... 190 00:17:22.100 --> 00:17:24.934 It's not easy, and so you have to work hard 191 00:17:24.934 --> 00:17:26.467 and keep your fingers crossed 192 00:17:26.467 --> 00:17:29.434 that you'll be able to solve the problems as they come up. 193 00:17:35.167 --> 00:17:38.834 The highlight of Hubble has been the Hubble Deep Field. 194 00:17:38.834 --> 00:17:41.701 This is where using the gyros and using 195 00:17:41.701 --> 00:17:46.267 the Fine Guidance Sensors that we change out and improve, 196 00:17:46.267 --> 00:17:48.434 we locked onto a place in the sky 197 00:17:48.434 --> 00:17:50.634 where there was nothing, no stars. 198 00:17:50.634 --> 00:17:54.167 Nothing could be seen there, and stared at it for 10 days 199 00:17:54.167 --> 00:17:57.767 just to see what was there, and it was amazing what we saw. 200 00:17:57.767 --> 00:18:00.667 We saw -- We were able, by staring 201 00:18:00.667 --> 00:18:04.334 and looking for a long time, we actually looked back in time, 202 00:18:04.334 --> 00:18:09.968 and we have a census of galaxies that are relatively new, 203 00:18:09.968 --> 00:18:12.934 some that are maybe only 6 billion years old 204 00:18:12.934 --> 00:18:15.467 and some that are near their... 205 00:18:15.467 --> 00:18:18.501 That are in the early years of the universe, 206 00:18:18.501 --> 00:18:21.901 and the
