1 00:00:01,735 --> 00:00:03,069 A desert river. 2 00:00:03,069 --> 00:00:06,239 Its verdant banks bursting with new vegetation. 3 00:00:07,974 --> 00:00:09,676 A sea of sand dunes 4 00:00:09,676 --> 00:00:12,679 blanketed with fresh snow. 5 00:00:12,679 --> 00:00:15,015 A mountain, its sides dazzling 6 00:00:15,015 --> 00:00:17,984 with the arrival of autumn's foliage. 7 00:00:18,284 --> 00:00:22,756 Images that not only captured the imagination, but more importantly 8 00:00:22,956 --> 00:00:24,624 tell a story. 9 00:00:24,624 --> 00:00:27,994 A story of our planet's surface ever evolving. 10 00:00:28,395 --> 00:00:31,831 A patchwork of rivers, mountains, deserts, 11 00:00:31,998 --> 00:00:35,001 oceans, farmlands and cities. 12 00:00:35,802 --> 00:00:38,805 A story told over the course of days, months, 13 00:00:39,205 --> 00:00:43,510 years and decades, all thanks to the Landsat program. 14 00:00:44,277 --> 00:00:46,846 Landsat actually was one of the things that first got me involved 15 00:00:46,846 --> 00:00:48,415 in remote sensing. 16 00:00:48,415 --> 00:00:52,986 Landsat provided that global perspective but still at the management 17 00:00:52,986 --> 00:00:54,821 scale resolution. 18 00:00:54,821 --> 00:01:00,293 level, field scale, but also provide that sort of whole earth scale resolution. 19 00:01:00,293 --> 00:01:02,262 And that was pretty exciting. 20 00:01:02,262 --> 00:01:05,398 For over 50 years, Landsat has watched over Earth, 21 00:01:05,765 --> 00:01:09,502 giving us critical insights into the way our planet is changing with us 22 00:01:09,836 --> 00:01:13,907 and around us Now eight satellites later. 23 00:01:14,040 --> 00:01:16,943 It's time for this story's next chapter. 24 00:01:16,943 --> 00:01:18,945 Landsat. Next. 25 00:01:24,350 --> 00:01:24,851 the next 26 00:01:24,851 --> 00:01:28,788 phase in the longest space based record of Earth's land surface 27 00:01:29,055 --> 00:01:33,359 will provide a host of new capabilities for the next generation of Landsat 28 00:01:33,359 --> 00:01:39,265 data users, including enhanced spatial resolution and 15 new spectral bands. 29 00:01:39,599 --> 00:01:42,569 But the most remarkable feature of this new mission. 30 00:01:42,569 --> 00:01:46,573 while previous Landsat missions have all featured one satellite, Landsat. 31 00:01:46,606 --> 00:01:49,909 Next will be a trio, a constellation of three 32 00:01:49,909 --> 00:01:52,912 observatories circling the globe in unison. 33 00:01:53,580 --> 00:01:56,583 even before the launch of the last Landsat, the user community 34 00:01:56,583 --> 00:02:01,221 was actually being queried about what was their needs for the next Landsat, 35 00:02:01,354 --> 00:02:05,091 one of the things that came back was all the users said, higher 36 00:02:05,091 --> 00:02:09,028 temporary visit was the highest thing that people were looking for. 37 00:02:09,129 --> 00:02:13,766 And the way you get higher temporary visit is, you either have a wider swath 38 00:02:13,900 --> 00:02:16,636 so that you're have a wider field of view. 39 00:02:16,636 --> 00:02:20,540 or you have more satellites that are viewing a larger portion 40 00:02:20,540 --> 00:02:22,175 of the earth all the time. 41 00:02:22,175 --> 00:02:27,347 we came up with this approach that utilizes three smaller observatories 42 00:02:27,347 --> 00:02:30,850 to meet that temporal revisit and incorporates 43 00:02:30,850 --> 00:02:34,287 those spatial resolution improvements and each observatory 44 00:02:34,287 --> 00:02:39,792 while maintaining the full spectral capability across each observatory 45 00:02:40,126 --> 00:02:44,564 This new triplet configuration will greatly improve the temporal revisit 46 00:02:44,564 --> 00:02:47,600 time from 16 days with Landsat nine 47 00:02:47,901 --> 00:02:52,539 down to just six days Landsat next will give scientists 48 00:02:52,539 --> 00:02:56,910 and data users a more precise view of how a scene changes over time. 49 00:02:57,343 --> 00:03:00,079 This can help highlight key stages of plant growth 50 00:03:00,079 --> 00:03:03,316 and is useful for crop management and estimating yield. 51 00:03:03,616 --> 00:03:08,588 one of the criteria actually we use to assess just even types of cover 52 00:03:08,655 --> 00:03:13,726 is based on when the crops emerge when they might be harvested. 53 00:03:13,893 --> 00:03:17,830 but also being able to look at different insect outbreaks, 54 00:03:17,964 --> 00:03:20,099 look at different effects of drought. 55 00:03:20,099 --> 00:03:24,204 All this stuff can happen very fast, so being able to respond quickly, 56 00:03:24,504 --> 00:03:29,042 this is an important aspect of being able to have this higher temporal revisit. 57 00:03:29,542 --> 00:03:33,012 Throughout the program's history, Landsat satellites have been able 58 00:03:33,012 --> 00:03:36,216 to chronicle the surface of our planet in stunning detail. 59 00:03:36,583 --> 00:03:40,353 Landsat next will look to push that capability even further. 60 00:03:40,954 --> 00:03:44,123 To understand the resolution of Landsat, We need to zoom 61 00:03:44,123 --> 00:03:47,393 all the way in until we see individual pixels. 62 00:03:47,527 --> 00:03:52,165 Each pixel of a Landsat eight or nine seen is about 30 square meters. 63 00:03:52,498 --> 00:03:56,903 Landsat next looks to improve this to ten meters, roughly nine times 64 00:03:56,903 --> 00:04:01,107 the resolution allowing us to pinpoint finer details within the image. 65 00:04:01,541 --> 00:04:02,775 this is fantastic. 66 00:04:02,775 --> 00:04:05,912 So now we'll be actually picking up about 40% 67 00:04:06,179 --> 00:04:10,083 more agricultural fields that we totally missed before. 68 00:04:10,083 --> 00:04:11,951 And that's just in the US alone. 69 00:04:11,951 --> 00:04:15,855 So some of these smaller agricultural fields, wind rows, 70 00:04:16,122 --> 00:04:19,359 crevasses and ice fields, those will be picked up. 71 00:04:19,359 --> 00:04:21,661 And new Landsat data, 72 00:04:21,661 --> 00:04:25,331 This enhanced spatial resolution won't be limited to just visible light. 73 00:04:25,698 --> 00:04:30,003 Thermal bands will also be getting an upgrade from 100 meters to 60 meters. 74 00:04:30,303 --> 00:04:31,037 A resolution 75 00:04:31,037 --> 00:04:34,941 dimensions slightly larger than the bottom of the Statue of Liberty pedestal. 76 00:04:35,708 --> 00:04:37,377 Urban areas like New York City 77 00:04:37,377 --> 00:04:41,080 are prone to suffering from a phenomenon called the heat Island effect. 78 00:04:41,414 --> 00:04:45,551 As an excess of impervious surfaces absorb and re emit, the sun's heat 79 00:04:45,885 --> 00:04:48,888 Using Landsat next's improved thermal resolution. 80 00:04:49,055 --> 00:04:51,658 Scientists and data users will have the ability 81 00:04:51,658 --> 00:04:54,661 to map the temperature of urban areas in finer detail, 82 00:04:54,961 --> 00:04:58,698 Possibly shedding light on better methods of sustainable urban development. 83 00:05:02,001 --> 00:05:04,937 Landsat imagery is well known for the vivid detail 84 00:05:04,937 --> 00:05:08,141 it provides of the Earth's surface, But Landsat satellites 85 00:05:08,141 --> 00:05:11,144 are actually collecting data from across the spectrum. 86 00:05:11,277 --> 00:05:12,211 starting with four. 87 00:05:12,211 --> 00:05:13,780 Spectral bands with Landsat. 88 00:05:13,780 --> 00:05:15,415 One through three, up to. 89 00:05:15,415 --> 00:05:18,084 11 bands with Landsat eight and nine. 90 00:05:18,084 --> 00:05:20,953 From visible to thermal infrared. 91 00:05:20,953 --> 00:05:25,658 Landsat next looks to push the program's spectral capabilities even further, 92 00:05:25,792 --> 00:05:28,728 boasting an additional 15 spectral bands, 93 00:05:28,728 --> 00:05:31,698 bringing the total to a whopping 26. 94 00:05:31,698 --> 00:05:34,100 With more than double the spectral bands of Landsat, 95 00:05:34,100 --> 00:05:37,837 eight and nine users will be able to glean even more information 96 00:05:37,837 --> 00:05:41,374 from Landsat next data allowing for better resource management, 97 00:05:41,507 --> 00:05:45,345 such as tracking water quality and detecting harmful algal blooms. 98 00:05:45,678 --> 00:05:50,116 coastal waterways, we're experiencing algae blooms like never before, 99 00:05:50,383 --> 00:05:54,520 those are health concerns for our population. 100 00:05:54,520 --> 00:05:58,624 being able to detect those and respond to them quickly, 101 00:05:59,058 --> 00:06:03,596 you know, that temporary visit and those new bands enable us to do that. 102 00:06:03,763 --> 00:06:08,835 The other thing is actually being able to better track dynamics of snow and ice. 103 00:06:09,102 --> 00:06:11,571 The melting snow and ice are used 104 00:06:11,571 --> 00:06:15,274 to recharge water sources, especially in the western US. 105 00:06:15,274 --> 00:06:19,879 So being able to know when those resources are going to be available determining 106 00:06:20,012 --> 00:06:24,417 potential for flooding versus recharge is very important for water management. 107 00:06:26,152 --> 00:06:26,686 It's often 108 00:06:26,686 --> 00:06:30,923 said that Landsat superpower is time travel, granting its users 109 00:06:30,923 --> 00:06:33,960 the ability to rewind the clock and observe the evolution 110 00:06:33,960 --> 00:06:36,963 of our planet's surface during the last half century. 111 00:06:37,363 --> 00:06:41,067 But the true key to unlocking Landsat its ability to travel in time 112 00:06:41,334 --> 00:06:45,772 has been the remarkable consistency in data quality across multiple decades. 113 00:06:45,772 --> 00:06:47,540 And Landsat missions. 114 00:06:47,540 --> 00:06:48,040 more than that. 115 00:06:48,040 --> 00:06:49,175 Actually, it's a time machine, 116 00:06:49,175 --> 00:06:52,211 but it's also a time in space machine, I would argue. 117 00:06:52,478 --> 00:06:55,782 it's not only being able to look back into time, 118 00:06:55,782 --> 00:06:59,485 I think it's also being able to look at different places on the globe 119 00:06:59,485 --> 00:07:03,289 and give in a consistent picture anywhere on the globe as well. 120 00:07:03,856 --> 00:07:05,725 And that's what Landsat allows us to do. 121 00:07:05,725 --> 00:07:07,860 There's a consistency in the measurements 122 00:07:07,860 --> 00:07:10,863 there's consistency in the way the instruments were calibrated. 123 00:07:11,230 --> 00:07:14,801 The reason why this is so important is the changes on earth. 124 00:07:14,801 --> 00:07:19,872 Will there be changes in vegetation or subtle changes on the Earth's surfaces 125 00:07:20,206 --> 00:07:23,409 that we want to make sure that that we're actually capturing these changes? 126 00:07:23,409 --> 00:07:26,412 And they aren't just changes in the instruments themselves. 127 00:07:26,546 --> 00:07:29,882 Landsat has been historically the gold standard reference 128 00:07:29,949 --> 00:07:35,221 for calibration of many different missions across the whole globe. 129 00:07:35,655 --> 00:07:39,025 the radiometric quality for Landsat next will be at least as good 130 00:07:39,025 --> 00:07:40,560 as any previous Landsat. 131 00:07:40,560 --> 00:07:45,064 So we will maintain that standard for calibration and referencing 132 00:07:45,064 --> 00:07:49,936 for all missions Landsat next three satellites improved. 133 00:07:49,936 --> 00:07:51,871 Six day temporal revisit. 134 00:07:51,871 --> 00:07:55,541 Enhanced spatial resolution and 26 spectral bands 135 00:07:55,708 --> 00:07:58,711 all add up to a massive amount of data. 136 00:07:58,711 --> 00:08:03,349 Landsat eight and nine each recorded around 750 scenes per day. 137 00:08:03,716 --> 00:08:07,887 with Landsat next trio of satellites, that number will skyrocket 138 00:08:07,954 --> 00:08:12,892 over 2200 scenes per day More scenes means more data 139 00:08:13,359 --> 00:08:16,362 this will be a huge increase in data volume. 140 00:08:16,362 --> 00:08:18,898 this means we're not going to be downloading data anymore. 141 00:08:18,898 --> 00:08:22,101 Get ready to be doing all your data processing in the cloud. 142 00:08:22,301 --> 00:08:26,172 missing data volume and management is is our number 143 00:08:26,172 --> 00:08:28,274 one challenge on on Landsat next. 144 00:08:28,274 --> 00:08:32,144 once we get that data to the ground, our partners at USGS 145 00:08:32,144 --> 00:08:35,882 who operate the ground network and ground systems, they can handle that 146 00:08:35,882 --> 00:08:40,086 transmission and then publish it and provide it to the cloud 147 00:08:40,086 --> 00:08:44,257 for all these users to have free and open access to this data. 148 00:08:44,423 --> 00:08:48,694 I can't stress enough how exciting that is for, any small university 149 00:08:48,694 --> 00:08:52,231 to be able to sign up and and tap into that data 150 00:08:53,065 --> 00:08:55,434 It's still early days for the Landsat next 151 00:08:55,434 --> 00:08:58,471 mission, slated for launch in late 2030. 152 00:08:58,704 --> 00:09:02,108 There's no shortage of work to be done over the next seven years, 153 00:09:02,575 --> 00:09:04,076 but plans for the new triplet 154 00:09:04,076 --> 00:09:07,713 constellation, upgraded spatial and temporal resolutions 155 00:09:07,980 --> 00:09:11,784 and added spectral bands have the Landsat next team excited. 156 00:09:12,118 --> 00:09:17,390 our mission right now is really a quantum step forward from previous Lance. 157 00:09:17,390 --> 00:09:19,559 That's this may be the biggest leap in capability 158 00:09:19,559 --> 00:09:23,162 since the launch of Lance S7 in we launch 159 00:09:23,162 --> 00:09:26,399 in 2030, it'll be the biggest improvement in 30 years. 160 00:09:26,766 --> 00:09:27,934 very, very excited. 161 00:09:27,934 --> 00:09:30,069 I can't wait to see what comes out 162 00:09:30,069 --> 00:09:34,574 of all of these emerging applications and how well it supports the user. 163 00:09:35,174 --> 00:09:38,611 Over the life of the Landsat program, the world's population 164 00:09:38,611 --> 00:09:41,714 has more than doubled, leading to increasing pressure 165 00:09:41,714 --> 00:09:44,717 on precious resources such as food and water. 166 00:09:45,151 --> 00:09:48,821 But time and time again, Landsat missions have only served 167 00:09:48,821 --> 00:09:52,658 to highlight humankind's innate ability to adapt to its environments, 168 00:09:53,059 --> 00:09:56,696 enabling us to develop better methods of sustainable resource management 169 00:09:57,229 --> 00:09:59,999 by helping farmers to monitor the health of their crops 170 00:09:59,999 --> 00:10:02,635 and efficiently manage their water resources 171 00:10:02,635 --> 00:10:06,138 by guiding forestry management programs on better ways to identify 172 00:10:06,138 --> 00:10:10,142 areas at risk for wildfires and track changes in land use over time, 173 00:10:10,710 --> 00:10:13,279 or by contributing to conservation efforts. 174 00:10:13,279 --> 00:10:17,617 Monitoring and assessing the biodiversity of coastal wetlands and protected areas. 175 00:10:18,150 --> 00:10:20,753 Landsat next will look to not only preserve this over 176 00:10:20,753 --> 00:10:23,889 50 year legacy, but bring it into the future. 177 00:10:24,624 --> 00:10:26,225 we live on this planet Earth. 178 00:10:26,225 --> 00:10:30,296 We all know that we want to leave this planet for our children. 179 00:10:30,463 --> 00:10:32,865 We know the importance of sustainability. 180 00:10:32,865 --> 00:10:35,034 And I think that's what Lance that's all about. 181 00:10:35,034 --> 00:10:39,872 it's about helping us manage the planet that we live on for the long term. 182 00:10:39,972 --> 00:10:42,842 And that's why it's there and that's why it continues to be here. 183 00:10:42,842 --> 00:10:45,578 And expect it to be there for the next generation as well. 184 00:16:23,449 --> 00:16:24,450 one of my most excited 185 00:16:24,450 --> 00:16:27,553 about there's there's two things I think I touched on one of them. 186 00:16:27,553 --> 00:16:29,555 What am I most excited about in Landsat? 187 00:16:29,555 --> 00:16:30,389 Next? 188 00:16:30,389 --> 00:16:33,359 Two things. One is, 189 00:16:33,625 --> 00:16:36,295 you know, and you've you've you've done this, too. 190 00:16:36,295 --> 00:16:40,866 Is that the sheer volume of data with Landsat next is going to be enormous. 191 00:16:42,267 --> 00:16:45,270 And that means we're not going to be downloading data. 192 00:16:45,337 --> 00:16:47,373 I never like downloading data. 193 00:16:47,373 --> 00:16:49,742 It's a waste of time. 194 00:16:49,742 --> 00:16:52,778 I think anybody that's downloading anything from the web, they know it's a 195 00:16:52,778 --> 00:16:56,315 that's a no one likes to sit there and wait for data to come to them. 196 00:16:56,315 --> 00:16:59,485 They'd rather be something else. And 197 00:17:00,853 --> 00:17:03,856 and I think being able to actually 198 00:17:04,323 --> 00:17:07,760 start working with the data online is going to be huge. 199 00:17:07,760 --> 00:17:11,597 And I think some of the new developments you've heard about with 200 00:17:12,131 --> 00:17:15,868 AI and machine learning language is also going to be huge 201 00:17:15,868 --> 00:17:19,304 too, especially as we get finer and finer resolution data. 202 00:17:19,605 --> 00:17:23,242 I think that's going to be huge in terms of what we can do with the data 203 00:17:23,242 --> 00:17:27,012 because there's going to be so much of the data I've already bragged 204 00:17:27,012 --> 00:17:30,015 that we're going to have higher temperature revisit. 205 00:17:30,215 --> 00:17:33,819 I've bragged that we're going to have more spectral brands bins. 206 00:17:34,253 --> 00:17:37,289 I've bragged that, you know, we're we're going to have 207 00:17:37,423 --> 00:17:40,626 higher, higher everything, more data, you know, 208 00:17:40,926 --> 00:17:45,497 And so that really opens up the door for machine learning and more computer 209 00:17:47,733 --> 00:17:48,834 capability 210 00:17:48,834 --> 00:17:51,837 than than than we've used in the past. 211 00:17:51,870 --> 00:17:53,372 And I'm really looking forward to that. 212 00:17:53,372 --> 00:17:57,776 And I think this is going to open up all doors for new possibilities 213 00:17:57,776 --> 00:18:00,779 in terms of what we can do with the data. 214 00:18:01,013 --> 00:18:04,349 Some people are scared about that, but I see it as a new opportunity 215 00:18:04,349 --> 00:18:07,319 and a new way of of analyzing the data. 216 00:18:07,986 --> 00:18:09,421 It gets me really excited. 217 00:18:09,421 --> 00:18:10,823 The other thing I'm excited 218 00:18:10,823 --> 00:18:14,760 by is, is the fact that we always seem to uncover new things. 219 00:18:14,760 --> 00:18:18,230 The more we keep studying, the longer we keep looking at something, 220 00:18:18,864 --> 00:18:21,867 the more we I guess my previous 221 00:18:22,267 --> 00:18:25,370 project scientist said the longer we keep studying 222 00:18:25,370 --> 00:18:28,373 things, the more 223 00:18:28,540 --> 00:18:29,975 the more observations. 224 00:18:29,975 --> 00:18:33,345 And the longer we keep studying something, the more we uncover. 225 00:18:34,079 --> 00:18:35,080 And it seems like 226 00:18:38,684 --> 00:18:39,952 the I mean, even 227 00:18:39,952 --> 00:18:43,822 even some of the observation, some of the theories 228 00:18:43,822 --> 00:18:47,893 put forth by Einstein were still challenging those observations. 229 00:18:47,893 --> 00:18:49,995 And I think the same is true for Landsat. 230 00:18:49,995 --> 00:18:54,600 The more data we come up with, we keep challenging our scientific theories. 231 00:18:55,067 --> 00:18:56,768 We keep developing new theories. 232 00:18:56,768 --> 00:19:00,806 I think there's nothing that doesn't get better with more observations 233 00:19:00,806 --> 00:19:04,276 and more time, and I think that's true with Landsat next to.
