WEBVTT 00:00:00.020 --> 00:00:03.540 Why should we spend money on NASA when we already have so many problems here on Earth? 00:00:03.540 --> 00:00:05.300 If somebody asked you this question, 00:00:05.309 --> 00:00:06.480 how would you answer? 00:00:06.490 --> 00:00:08.370 It's been nearly five years since I left 00:00:08.370 --> 00:00:13.049 But I came back to NASA's Jet Propulsion Laboratory today to help answer this tough question 00:00:13.049 --> 00:00:17.038 But before I even get to the five reasons I think we should spend money on NASA 00:00:17.039 --> 00:00:19.709 I need to clear one thing up. What percentage of the US budget 00:00:19.709 --> 00:00:24.800 Do you think goes to NASA? According to polls most Americans think it's 20 percent so it should come as no surprise 00:00:25.240 --> 00:00:29.500 That one in four Americans think that NASA's budget should be reduced. 00:00:29.500 --> 00:00:32.700 If you say the total budget represents a dollar or 100 pennies 00:00:32.700 --> 00:00:36.660 The truth is NASA gets less than one-half of one penny. 00:00:36.660 --> 00:00:43.980 For comparison, 16% goes to the military and 60% goes to social programs like Social Security, unemployment, Medicare and health care. 00:00:43.980 --> 00:00:45.980 Okay, so if that is our foundation 00:00:45.980 --> 00:00:52.420 Let me give you five incredible things that we get in return for that half a percent or less than nine dollars a year for most Americans 00:00:54.180 --> 00:00:55.580 Just like some might ask 00:00:55.580 --> 00:01:00.059 Why should we spend time exploring space when we have so many problems here on Earth? Some of our ancestors probably asked 00:01:00.060 --> 00:01:05.280 "Why should we waste time trying to figure out agriculture when we have so much work to do hunting and gathering?" or 00:01:05.280 --> 00:01:09.360 "Why should we spend so much time messing around in boats when we have so many issues here on the land?" 00:01:09.360 --> 00:01:11.440 And the answer to all three of these questions is the same: 00:01:11.440 --> 00:01:19.380 Reaching for new heights often creates new solutions and opportunities for people back on the ground, and I have some personal experience with this concept 00:01:19.380 --> 00:01:20.460 As most of you guys know by now, 00:01:20.460 --> 00:01:23.369 I spent seven of my nine years here at NASA working on the 00:01:23.440 --> 00:01:27.700 Curiosity rover in fact some of my hardware is still working like a champ on the top deck of the rover 00:01:27.700 --> 00:01:31.259 I'll be it a little dirtier since I touched it last but for my last two years here 00:01:31.260 --> 00:01:35.140 I worked on a much lesser known project called SMAP and in some ways 00:01:35.140 --> 00:01:42.200 I'm more proud of what it represents because SMAP is a super complex Earth orbiting satellite. Here's how it works. 00:01:42.200 --> 00:01:47.100 Once it's in orbit the antenna boom is deployed and in this 20 foot gold mesh reflector 00:01:47.100 --> 00:01:53.780 Origamis out like one of those Hoberman's sphere toys, and then the whole thing starts freaking spinning at 15 rpm 00:01:53.780 --> 00:01:58.340 And it's using a Radiometer that can see through the clouds to measure the soil moisture levels on earth 00:01:58.340 --> 00:02:02.700 This is important because soil moisture is one of the key vital signs of the planet. 00:02:02.700 --> 00:02:06.180 By measuring the moisture levels in the soil, it allows you to predict droughts, 00:02:06.180 --> 00:02:11.840 monitor floods and even predict crop yields for a given year and because the antenna spins around like that, 00:02:11.840 --> 00:02:15.720 you're able to measure all the soil on Earth every two to three days. 00:02:15.720 --> 00:02:18.960 So I left before it actually launched in 2015, 00:02:18.960 --> 00:02:24.120 so the reason I am here today is to follow up with some SMAP research scientists to see how things turned out 00:02:25.080 --> 00:02:32.900 I've been to many countries in Africa. People know about SMAP and the national government of those countries are trying to use it especially 00:02:32.900 --> 00:02:39.800 for drought especially for crop monitoring. So NASA has a data access policy of you know making it free for everybody 00:02:39.800 --> 00:02:42.960 There are three major cereal crop on the earth 00:02:42.960 --> 00:02:48.020 wheat, rice and corn. If you can forecast these three major crops 00:02:48.020 --> 00:02:55.060 So you know 70-80 percent of you know forecast you can do the crop field of the whole world. What Narenda is saying here is 00:02:55.060 --> 00:03:00.440 Remarkable to me, and it sums up my first point perfectly SMAP costs to 900 million dollars 00:03:00.520 --> 00:03:06.660 Africa is the continent with the most extreme poverty today. I did the math and for 900 million dollars 00:03:06.660 --> 00:03:09.780 You could feed all of Africa for less than a day 00:03:09.780 --> 00:03:15.140 But instead we invested in research and technology which empowers them to better help themselves 00:03:15.440 --> 00:03:18.220 Increasing the amount of food they can make on their own 00:03:18.220 --> 00:03:23.780 For decades as opposed to a one-time fleeting handout. Of the 37 missions currently running at JPL 00:03:23.800 --> 00:03:29.000 I think it's so cool that about half are studying and helping earth, just like SMAP 00:03:30.760 --> 00:03:31.800 This is a fancy way of saying 00:03:31.800 --> 00:03:37.040 We should be doing everything within our power to make sure that nothing catastrophically bad happens to us 00:03:37.040 --> 00:03:44.160 Hollywood got this right when they said that a large asteroid impact would be really bad news. Now the chances of this happening are small 00:03:44.160 --> 00:03:47.920 But the potential consequences are so large just ask these guys 00:03:47.920 --> 00:03:54.840 It makes sense to take it seriously. NASA has already put an asteroid early warning detection system in place and in October 00:03:54.840 --> 00:03:58.520 2022 for the first time ever they will test ramming a 00:03:58.520 --> 00:04:03.440 Spacecraft into an asteroid to see if you can deflect it off course with a mission called DART 00:04:03.440 --> 00:04:06.740 But perhaps an even bigger threat to humans are humans 00:04:07.400 --> 00:04:11.760 one of the goals of all of the Rovers that we sent to Mars is to gather data on what 00:04:11.760 --> 00:04:13.490 It would take for humans to live there 00:04:13.490 --> 00:04:20.320 Establishing a permanent human outpost on Mars would serve sort of like a backup hard drive for your computer in case something catastrophically bad 00:04:20.320 --> 00:04:21.500 happened here on earth 00:04:23.840 --> 00:04:28.720 America's first satellite was built here at JPL and now satellites make it so we can get GPS 00:04:28.720 --> 00:04:36.300 driving directions on our phone or get TV beamed down to us from space or predict the path of hurricanes with much greater accuracy 00:04:36.300 --> 00:04:40.940 Theword pixel in the concept of the first digital camera was also invented at JPL in the 00:04:40.940 --> 00:04:45.980 1960s when an engineer was trying to solve how to get pictures of the planets and send them back to earth 00:04:45.980 --> 00:04:47.040 In fact there are nearly 00:04:47.040 --> 00:04:49.300 2,000 NASA technology spin-offs 00:04:49.300 --> 00:04:54.360 We don't know what we don't know and so expecting NASA to justify its funding 00:04:54.360 --> 00:04:58.200 But predicting all the amazing things it will discover would be like 00:04:58.240 --> 00:05:05.000 Expecting Christopher Columbus when he was lobbying Queen Isabella for ships to predict the polio vaccine or Netflix 00:05:07.160 --> 00:05:13.660 Of the 18 billion that NASA gets it's not like they're just putting that money on a rocket and launching it into space 00:05:13.660 --> 00:05:16.059 The Majority of that money goes towards the salaries of 00:05:16.059 --> 00:05:21.328 Tens of thousands of some of America's most skilled workers and one of the counter arguments here is yeah 00:05:21.328 --> 00:05:23.760 But why do we need the government to fund these programs? 00:05:23.760 --> 00:05:29.920 Why not let private companies do the innovating? Private space companies like SpaceX or Blue Origin are awesome 00:05:29.920 --> 00:05:31.269 And they play an important role 00:05:31.269 --> 00:05:39.320 But they're incentivized to pursue technologies that will give them a return on investment like space tourism or asteroid mining or launching satellites for other 00:05:39.320 --> 00:05:40.079 organizations 00:05:40.079 --> 00:05:43.499 there's just no incentive for a private company to invest in tracking and 00:05:43.599 --> 00:05:48.389 Deflecting asteroids or investing in earth science missions like SMAP and then making the data 00:05:48.520 --> 00:05:53.920 Available for free to anyone who needs it. So to recap for that less than half a penny from a dollar 00:05:53.940 --> 00:06:00.560 Investment in NASA, not only do we improve life on Earth through projects like SMAP and protect ourselves against really catastrophic 00:06:00.560 --> 00:06:04.760 Events and discover other incredible technologies to improve our lives along the way 00:06:04.760 --> 00:06:05.940 But the money to make all that happen 00:06:06.140 --> 00:06:12.320 goes back into growing the economy through the salaries of all the smart people doing their work. And my fifth and final reason why we 00:06:12.320 --> 00:06:19.500 Should spend money on NASA even when we still have unsolved problems here on earth is perhaps the most important even if less concrete 00:06:22.120 --> 00:06:26.680 Think it's captured best by what some call the most important picture ever taken 00:06:26.680 --> 00:06:30.960 What you see here is the result of a 10-day exposure image from the Hubble Deep Space 00:06:30.960 --> 00:06:34.660 Telescope with the exception of these three dots which are single stars 00:06:34.660 --> 00:06:41.660 Every speck, smudge, and spiral you see in this image is a galaxy with hundreds of billions of stars 00:06:41.660 --> 00:06:43.840 Just like our own Milky Way galaxy 00:06:44.160 --> 00:06:52.460 Most remarkably the field of view captured here is the darkest part of the night sky the size of Roosevelt's eye on a dime 00:06:52.460 --> 00:06:58.640 Held at arm's length we send men to the moon and orbiters to Saturn and Rovers to Mars 00:06:58.640 --> 00:07:02.920 Not necessarily because there's some financial incentive or some quick payoff 00:07:02.920 --> 00:07:09.500 We're looking to exploit, but because as humans there are fundamental burning questions we're eager to answer 00:07:09.520 --> 00:07:15.420 The first person to set foot on Mars is alive right now. They could be in junior high or high school 00:07:15.420 --> 00:07:19.460 He or she could be watching this video right now 00:07:19.460 --> 00:07:24.280 It could be you I feel that our continued exploration of space in all its forms 00:07:24.280 --> 00:07:29.200 fills me with hope and inspires me to reach higher and makes me a better person 00:07:31.400 --> 00:07:35.940 I want to thank Bill and Melinda Gates for teaming up with me on this video if you want to know why they think there's still a 00:07:35.940 --> 00:07:41.480 Case for being an optimist in today's world even with all the negative headlines you should check out the Bill and Melinda Gates 00:07:41.480 --> 00:07:48.540 Annual letter at gatesletter.com this optimism stems from facts like the number of children who die every year has been cut in half 00:07:48.540 --> 00:07:55.400 so has extreme poverty declining by half in less than twenty years and more children are attending school now than ever before but we're 00:07:55.400 --> 00:07:58.020 Optimistic not just because we know life used to be worse 00:07:58.020 --> 00:08:03.040 It's seeing the positive trend line of all the ongoing work by brilliant folks like at NASA and elsewhere 00:08:03.040 --> 00:08:07.940 Who are working to improve life on Earth by solving some of the world's toughest challenges 00:08:07.940 --> 00:08:10.220 I will leave a link to the letter in the video description
