1 00:00:00,000 --> 00:00:07,000 Thanks you guys. And by the way, I still haven't forgotten about that third question I asked you earlier in the program. 2 00:00:07,000 --> 00:00:11,000 How is the Earth system part of larger systems? 3 00:00:11,000 --> 00:00:14,000 I'll get your answers a little later in the program. 4 00:00:14,000 --> 00:00:18,000 But first, did you know NASA has three important mission statements? 5 00:00:18,000 --> 00:00:24,000 They are to understand and protect our home planet, to explore the universe and search for life, 6 00:00:24,000 --> 00:00:29,000 and to inspire the next generation of explorers, as only NASA can. 7 00:00:29,000 --> 00:00:35,000 So how do these NASA mission statements apply to the study of the Earth and beyond? 8 00:00:35,000 --> 00:00:41,000 Well, Dr. J. Marshall Shepard from NASA's Office of Earth Science has the scoop. 9 00:00:41,000 --> 00:00:43,000 Thanks, Jennifer. 10 00:00:43,000 --> 00:00:47,000 The Earth Science Application Program focuses on applications of national priority 11 00:00:47,000 --> 00:00:51,000 to expand and accelerate the use of knowledge, science, and technologies 12 00:00:52,000 --> 00:00:54,000 resulting from the Earth Science Enterprise mission 13 00:00:54,000 --> 00:00:58,000 of improving predictions in weather, climate, and natural hazards. 14 00:00:58,000 --> 00:01:03,000 NASA has identified 12 applications of national priority to benefit society. 15 00:01:03,000 --> 00:01:08,000 They are energy forecasting, agricultural efficiency, carbon management, 16 00:01:08,000 --> 00:01:13,000 aviation safety, homeland security, community growth management, 17 00:01:13,000 --> 00:01:17,000 disaster preparedness, public health, coastal management, 18 00:01:17,000 --> 00:01:23,000 biological invasive species, water management and conservation, and air quality management. 19 00:01:23,000 --> 00:01:28,000 Essentially, NASA operates many scientific missions through partnerships with public, 20 00:01:28,000 --> 00:01:32,000 private, and academic institutions to study the Earth and its subsystems. 21 00:01:32,000 --> 00:01:36,000 Earth systems scientists analyze the data to learn how the different subsystems 22 00:01:36,000 --> 00:01:39,000 work together to function as a complete whole. 23 00:01:39,000 --> 00:01:44,000 Then, federal agencies such as the Department of Energy, Federal Aviation Administration, 24 00:01:44,000 --> 00:01:48,000 U.S. Department of Agriculture, U.S. Geological Survey Society, 25 00:01:48,000 --> 00:01:51,000 National Oceanic and Atmospheric Administration, 26 00:01:51,000 --> 00:01:55,000 and other agencies use our data to develop application tools 27 00:01:55,000 --> 00:01:58,000 to help improve the quality of life here on Earth. 28 00:01:58,000 --> 00:02:03,000 It's important that we all work together to make sure our planet is livable for many generations to come. 29 00:02:03,000 --> 00:02:05,000 Here's a question to think about. 30 00:02:05,000 --> 00:02:09,000 Choose four of the 12 applications and try to determine what Earth subsystem 31 00:02:10,000 --> 00:02:14,000 lithosphere, hydrosphere, biosphere, or atmosphere, 32 00:02:14,000 --> 00:02:17,000 or subsystems it's associated with. 33 00:02:17,000 --> 00:02:21,000 Then discuss your answers amongst your peers and teacher. 34 00:02:21,000 --> 00:02:23,000 As the teacher pauses the program, 35 00:02:23,000 --> 00:02:27,000 keep in mind how Jennifer defined what a system is earlier in the program. 36 00:02:27,000 --> 00:02:30,000 Are you starting to understand about the concept of systems? 37 00:02:30,000 --> 00:02:32,000 Good! 38 00:02:32,000 --> 00:02:34,000 Jennifer mentioned NASA's mission statement. 39 00:02:34,000 --> 00:02:37,000 First part is to protect and understand our home planet. 40 00:02:37,000 --> 00:02:41,000 Data collected by NASA satellites contribute greatly to our understanding 41 00:02:41,000 --> 00:02:45,000 and ability to forecast weather, climate patterns, and natural hazards. 42 00:02:45,000 --> 00:02:50,000 The second part of NASA's mission statement is to explore the universe and search for life. 43 00:02:50,000 --> 00:02:53,000 Applications developed from Earth system science data 44 00:02:53,000 --> 00:02:56,000 could potentially be used to study the other planets in the solar system. 45 00:02:56,000 --> 00:02:58,000 Speaking of our solar system, 46 00:02:58,000 --> 00:03:03,000 I believe that Jennifer hasn't answered the question regarding how our Earth is a part of larger systems. 47 00:03:04,000 --> 00:03:08,000 The third part of NASA's mission statement definitely applies to you, 48 00:03:08,000 --> 00:03:11,000 to inspire the next generation of explorers. 49 00:03:11,000 --> 00:03:14,000 Understanding how the Earth works and environmental awareness 50 00:03:14,000 --> 00:03:17,000 are topics that challenge and excite the youth of today. 51 00:03:17,000 --> 00:03:20,000 We need future scientists and engineers like you 52 00:03:20,000 --> 00:03:24,000 to continue to bring real scientific breakthroughs in studying our planet. 53 00:03:24,000 --> 00:03:29,000 By the way, do you know what careers are related to the study of Earth system science? 54 00:03:29,000 --> 00:03:33,000 Well, I created a list of a variety of applications related to careers. 55 00:03:33,000 --> 00:03:35,000 Let's take a look at them. 56 00:03:35,000 --> 00:03:40,000 Forestry, migration of populations, water management, 57 00:03:40,000 --> 00:03:44,000 agriculture such as crop forecasting and fish catch, 58 00:03:44,000 --> 00:03:49,000 health issues such as famine or outbreaks of asthma and other diseases, 59 00:03:49,000 --> 00:03:55,000 technological instrumentation applications based on satellite and other types of remote sensing, 60 00:03:55,000 --> 00:03:58,000 and weather forecasting and weather-related events. 61 00:03:58,000 --> 00:04:02,000 Can you match some of the careers you thought of with my applications list? 62 00:04:02,000 --> 00:04:06,000 I bet you didn't realize that there are a lot of careers associated with studying the Earth, 63 00:04:06,000 --> 00:04:09,000 and mathematics is a fundamental skill in all. 64 00:04:09,000 --> 00:04:12,000 The last part of the mission statement says, 65 00:04:12,000 --> 00:04:15,000 as only NASA can. 66 00:04:15,000 --> 00:04:18,000 NASA contributes scientific research and technology, 67 00:04:18,000 --> 00:04:23,000 which our partners use to develop innovative approaches for Earth science applications worldwide. 68 00:04:23,000 --> 00:04:27,000 It's important to understand how the Earth functions as a whole 69 00:04:27,000 --> 00:04:32,000 and to meet the needs to help manage forest fires, coastal environments, agriculture, 70 00:04:32,000 --> 00:04:37,000 impacts of infectious diseases, aviation safety, and hurricane forecasting. 71 00:04:37,000 --> 00:04:43,000 So the next time you watch the news and hear about hurricanes, floods, wildfires, earthquakes, 72 00:04:43,000 --> 00:04:48,000 or a volcano erupting, take a moment and think about how it might be impacting your local area. 73 00:04:48,000 --> 00:04:50,000 Jennifer, back to you.
