WEBVTT - Asteroid Gold Rush

0:00:03.800 --> 0:00:06.680
<v Speaker 1>Welcome to Stuff to Blow your Mind from how Stuff

0:00:06.720 --> 0:00:13.480
<v Speaker 1>Works dot com. Hey, you're welcome to Stuff to Blow

0:00:13.480 --> 0:00:15.360
<v Speaker 1>your Mind. My name is Robert Lamb and I am

0:00:15.440 --> 0:00:17.800
<v Speaker 1>Julie Douglas. You know, the universe is out there, just

0:00:17.880 --> 0:00:20.239
<v Speaker 1>waiting for us to explore it. And as we explore it,

0:00:20.960 --> 0:00:24.759
<v Speaker 1>of course we're going to ravage it for resources when appropriate,

0:00:24.760 --> 0:00:26.520
<v Speaker 1>when we need it, because we're gonna need stuff out there.

0:00:26.520 --> 0:00:28.520
<v Speaker 1>We're gonna need to build things, We're gonna need to

0:00:28.600 --> 0:00:33.080
<v Speaker 1>drink things, to eat, things, live on things. So it's

0:00:32.320 --> 0:00:35.440
<v Speaker 1>a form, you know, we need to get out there

0:00:35.520 --> 0:00:37.440
<v Speaker 1>and really start to get some real estate out there.

0:00:37.479 --> 0:00:39.440
<v Speaker 1>As far as we know, there are no extraterrestrials. There's

0:00:39.479 --> 0:00:41.760
<v Speaker 1>no one to dispute our claim, so it's all ours.

0:00:43.479 --> 0:00:46.400
<v Speaker 1>You think, you think? Yeah, I mean, actually we are

0:00:46.440 --> 0:00:49.199
<v Speaker 1>going to talk about something that has been in the

0:00:49.240 --> 0:00:53.560
<v Speaker 1>news quite a bit, asteroid mining. And just recently NASA

0:00:53.600 --> 0:00:57.040
<v Speaker 1>announced that starting next month, the six astronauts are headed

0:00:57.080 --> 0:01:02.080
<v Speaker 1>to the NASA Extreme Environment Mission Operation, the underwater habitat

0:01:02.400 --> 0:01:04.760
<v Speaker 1>off the Florida coast that will serve as a simulator

0:01:04.920 --> 0:01:09.000
<v Speaker 1>for the long duration mission to an asteroid. Yeah, this

0:01:09.080 --> 0:01:11.679
<v Speaker 1>is pretty amazing. Stuff. Just to give a quick rundown

0:01:11.680 --> 0:01:14.960
<v Speaker 1>of our history exploring asteroids, I should point out that

0:01:15.040 --> 0:01:17.680
<v Speaker 1>the first spacecraft to take close up images of asteroids

0:01:17.760 --> 0:01:20.640
<v Speaker 1>was NASA's Galileo in ninety one. Is also discovered the

0:01:20.640 --> 0:01:25.240
<v Speaker 1>first moon orban an asteroid in n In two thousand one.

0:01:25.480 --> 0:01:29.400
<v Speaker 1>After NASA's Near spacecraft intensely studied the near Earth asteroid

0:01:29.600 --> 0:01:32.800
<v Speaker 1>Eros for more than a year from orbit, mission, astroders

0:01:32.840 --> 0:01:34.959
<v Speaker 1>decided to trying to land a spacecraft on it, although

0:01:34.959 --> 0:01:38.720
<v Speaker 1>it wasn't designed for landing, near successfully touchdown, setting the

0:01:38.800 --> 0:01:41.640
<v Speaker 1>record of the first craft to successfully land an asteroid.

0:01:41.800 --> 0:01:45.280
<v Speaker 1>Two thousand six, Japan'shyabusa became the first spacecraft to land

0:01:45.360 --> 0:01:48.720
<v Speaker 1>on and take off from an asteroid. And then NASA's

0:01:48.760 --> 0:01:52.120
<v Speaker 1>Don mentioned launched in two thousand seven, began exploring Vesta

0:01:52.320 --> 0:01:54.960
<v Speaker 1>the asteroid in two thousand eleven, and that brings us

0:01:54.960 --> 0:01:57.920
<v Speaker 1>pretty much up to modern times. Yeah, and Japan saw

0:01:57.960 --> 0:02:00.920
<v Speaker 1>high of USA also took sample from the asteroid to

0:02:00.960 --> 0:02:03.120
<v Speaker 1>which we're going to talk about, also managed to salute

0:02:03.160 --> 0:02:05.200
<v Speaker 1>it a little bit. Yeah, yeah, a little bit. Now,

0:02:05.200 --> 0:02:08.720
<v Speaker 1>what is an asteroid? Right? An asteroid is a small, airless,

0:02:08.960 --> 0:02:12.560
<v Speaker 1>rocky world revolving around the Sun. They're too small to

0:02:12.560 --> 0:02:15.560
<v Speaker 1>be called planets. Some of them are also called planetoids

0:02:15.639 --> 0:02:18.400
<v Speaker 1>or minor planets, and in total, all of them combined,

0:02:18.520 --> 0:02:21.640
<v Speaker 1>their mass is less than that of Earth's moon. It's true,

0:02:21.680 --> 0:02:24.920
<v Speaker 1>it's true. And they are found between Mars and Jupiter.

0:02:25.040 --> 0:02:27.840
<v Speaker 1>And the idea is that when Jupiter was a new world,

0:02:28.000 --> 0:02:29.880
<v Speaker 1>we have the formation, so there's just about four point

0:02:29.919 --> 0:02:33.480
<v Speaker 1>six billion years ago, Jupiter prevented any planetary bodies from

0:02:33.560 --> 0:02:37.720
<v Speaker 1>forming between that gap of Mars and Jupiter, and that

0:02:37.760 --> 0:02:41.040
<v Speaker 1>created this asteroid belt, the bit of debris of the

0:02:41.200 --> 0:02:43.960
<v Speaker 1>leftover material. It's kind of like when you're making a

0:02:44.000 --> 0:02:47.080
<v Speaker 1>cake or something, or making some bread, They're always going

0:02:47.120 --> 0:02:49.400
<v Speaker 1>to be a little leftovers, right, Yeah, and we all

0:02:49.440 --> 0:02:52.399
<v Speaker 1>know that sometimes the leftovers are actually more delicious than

0:02:52.480 --> 0:02:56.120
<v Speaker 1>the finished baked good itself, which means your finger wants

0:02:56.160 --> 0:02:58.800
<v Speaker 1>to dock those leftovers and bring it to your mouth

0:02:58.840 --> 0:03:00.959
<v Speaker 1>to taste it, and they tatically. That is what we're

0:03:01.000 --> 0:03:03.760
<v Speaker 1>talking about. Yeah, there's some there's some wonderful stuff and

0:03:03.800 --> 0:03:06.560
<v Speaker 1>these leftovers that could certainly be of use to us.

0:03:06.760 --> 0:03:09.639
<v Speaker 1>For instance, there's platinum, yes, which I have the data

0:03:09.680 --> 0:03:11.400
<v Speaker 1>here on how much that would work. Oh yeah, it's

0:03:11.440 --> 0:03:15.320
<v Speaker 1>only worthy. And when we don't have the exact math

0:03:15.400 --> 0:03:17.600
<v Speaker 1>on it, you're talking about trillions of dollars from the

0:03:17.680 --> 0:03:21.720
<v Speaker 1>plotential to mind, trillions of dollars of platinum from these asteroids.

0:03:21.840 --> 0:03:24.440
<v Speaker 1>Then you have gold, which we all love, of course,

0:03:24.520 --> 0:03:27.440
<v Speaker 1>and is also useful in the circuitry and other methods

0:03:27.480 --> 0:03:30.720
<v Speaker 1>that beyond mere jewelry. And then they're rare earth minerals.

0:03:30.760 --> 0:03:33.919
<v Speaker 1>There's water, which doesn't sound all that amazing at first

0:03:33.919 --> 0:03:36.600
<v Speaker 1>because you're thinking, well, we have water here, but if

0:03:36.640 --> 0:03:39.760
<v Speaker 1>we are planning to eventually move out into space and

0:03:39.800 --> 0:03:42.560
<v Speaker 1>to explore the cosmos, we're gonna need more water, and

0:03:42.560 --> 0:03:45.040
<v Speaker 1>we're gonna need water from sources that are closer at

0:03:45.080 --> 0:03:48.760
<v Speaker 1>hand than the home world, so we can conceivably harvest

0:03:48.800 --> 0:03:52.320
<v Speaker 1>it from these rocky planetoids. And then we could also

0:03:52.480 --> 0:03:55.040
<v Speaker 1>use the hydrogen an oxygen from that water to produce

0:03:55.080 --> 0:03:57.800
<v Speaker 1>fuel for our space crafts. Right right, So basically, you

0:03:57.840 --> 0:04:00.480
<v Speaker 1>would have all these materials available to you in space,

0:04:00.760 --> 0:04:03.280
<v Speaker 1>right even have to hike them from Earth to yeah,

0:04:03.320 --> 0:04:05.920
<v Speaker 1>because especially if you're bringing from the planet surface, you're

0:04:05.920 --> 0:04:09.280
<v Speaker 1>talking about the cost of traveling. You need a heavy

0:04:09.320 --> 0:04:11.640
<v Speaker 1>lift vehicle for that and then you're gonna have to

0:04:11.680 --> 0:04:13.880
<v Speaker 1>transport it the rest of the way to wherever you are.

0:04:14.320 --> 0:04:17.680
<v Speaker 1>It's a classic example of the supply chain. Far better

0:04:17.760 --> 0:04:21.799
<v Speaker 1>to obtain goods and water and foods or whatever along

0:04:21.839 --> 0:04:23.640
<v Speaker 1>the way than to ship it all the way to you.

0:04:24.000 --> 0:04:26.880
<v Speaker 1>I read somewhere that one leader of water is basically

0:04:26.920 --> 0:04:31.640
<v Speaker 1>worth in space. So you know that availability of that

0:04:31.720 --> 0:04:34.760
<v Speaker 1>specific water there. Okay. So there are a lot of

0:04:34.760 --> 0:04:38.040
<v Speaker 1>people who are trying to round up these asteroids or

0:04:38.080 --> 0:04:40.760
<v Speaker 1>thinking about, I should say, and one of the big

0:04:40.760 --> 0:04:44.960
<v Speaker 1>players is a company called Planetary Resources. Co founders of

0:04:45.000 --> 0:04:49.799
<v Speaker 1>Planetary Resources are Peter Diamondus might diming this. He created

0:04:49.839 --> 0:04:53.599
<v Speaker 1>the really successful ex Prize Foundation that gives awards to

0:04:53.880 --> 0:04:58.880
<v Speaker 1>accomplishments in technology, particularly space, and Eric Anderson ex Prize

0:04:59.160 --> 0:05:02.680
<v Speaker 1>board member and chairman of the board of Space Flight Federation.

0:05:02.839 --> 0:05:07.360
<v Speaker 1>And then several x NASA engineers and astronauts, some planetary scientists,

0:05:07.560 --> 0:05:11.680
<v Speaker 1>and then just like a little gaggle of billionaires, UM

0:05:11.800 --> 0:05:16.080
<v Speaker 1>filmmaker James Cameron, Google executive Larry Page, Eric Schmidt, so

0:05:16.200 --> 0:05:18.720
<v Speaker 1>on and so forth. Ross pro Jr. On one hand,

0:05:18.760 --> 0:05:20.960
<v Speaker 1>we have people with more money than they know what

0:05:21.000 --> 0:05:23.040
<v Speaker 1>to do with. People with a lot of money, who

0:05:23.080 --> 0:05:25.280
<v Speaker 1>are dreamers. I mean, certainly James Cameron is a great

0:05:25.279 --> 0:05:27.600
<v Speaker 1>example of somebody with lots of money and in some

0:05:27.800 --> 0:05:30.680
<v Speaker 1>very heartfelt ideas about where we are in the world

0:05:30.839 --> 0:05:34.280
<v Speaker 1>and where we could go from here. So so there's that,

0:05:34.320 --> 0:05:36.120
<v Speaker 1>and then you have the X Prize individuals and the

0:05:36.400 --> 0:05:41.560
<v Speaker 1>X Prize mindset of let's stir up commercial interest in space,

0:05:41.880 --> 0:05:44.360
<v Speaker 1>let's get this going, let's get people interesting, let's get

0:05:44.360 --> 0:05:47.440
<v Speaker 1>these projects moving, because that is the future of space travel.

0:05:47.720 --> 0:05:50.440
<v Speaker 1>It's like the X Men of asteroid mining. I guess

0:05:50.440 --> 0:05:52.560
<v Speaker 1>you could say, right, um, in a way, I mean

0:05:52.600 --> 0:05:54.240
<v Speaker 1>what you have is you've got the vision, you've got

0:05:54.279 --> 0:05:56.080
<v Speaker 1>the money, and you've got to know how. That's why

0:05:56.120 --> 0:05:57.960
<v Speaker 1>we wanted to mention all these different names and the

0:05:58.000 --> 0:06:00.560
<v Speaker 1>people who are involved in their just to give you

0:06:00.560 --> 0:06:03.800
<v Speaker 1>guys an impa of how very serious this actually is.

0:06:03.839 --> 0:06:07.360
<v Speaker 1>That this will be happening, probably very soon, and they

0:06:07.360 --> 0:06:10.440
<v Speaker 1>have a game plan three phases. The first phase is

0:06:10.480 --> 0:06:14.520
<v Speaker 1>Acrid one hundred, that's the spacecraft series, Accord one hundred series,

0:06:14.560 --> 0:06:16.839
<v Speaker 1>and they're planning to launch this in twenty four months.

0:06:17.240 --> 0:06:19.440
<v Speaker 1>This is how a series of crafts would be. Basically

0:06:19.560 --> 0:06:23.960
<v Speaker 1>a space telescope based system aimed at identifying possible targets

0:06:23.960 --> 0:06:27.080
<v Speaker 1>for exploration. So Phase one Accord one hundred is all

0:06:27.080 --> 0:06:29.560
<v Speaker 1>about let's because some telescopes up there so that we

0:06:29.600 --> 0:06:32.320
<v Speaker 1>can figure out where we want to target, where we

0:06:32.360 --> 0:06:34.680
<v Speaker 1>want to go. Yeah, they're cutting metal on that right now,

0:06:34.760 --> 0:06:37.240
<v Speaker 1>so that's happening. And then the next phase is the

0:06:37.240 --> 0:06:40.799
<v Speaker 1>two hundred series, and that is about propulsion. That's about

0:06:40.839 --> 0:06:45.200
<v Speaker 1>getting these crafts, these various spacecrafts to those asteroids that

0:06:45.240 --> 0:06:48.560
<v Speaker 1>we picked out in phase one. And then finally there

0:06:48.560 --> 0:06:51.200
<v Speaker 1>comes the three hundred series. And in the three hundred

0:06:51.240 --> 0:06:55.520
<v Speaker 1>series we consist of swarms of robotic spacecraft that complete

0:06:55.520 --> 0:06:59.320
<v Speaker 1>the prospecting and begin to extract the water or platinum

0:06:59.400 --> 0:07:01.839
<v Speaker 1>or gold or what have you from these asteroids and

0:07:01.920 --> 0:07:06.159
<v Speaker 1>bringing them back home. So Phase one find them, phase

0:07:06.240 --> 0:07:09.920
<v Speaker 1>to travel to them, Phase three prospect and bring it

0:07:09.960 --> 0:07:13.480
<v Speaker 1>back right. These are a series of calculated, smaller missions

0:07:13.520 --> 0:07:15.600
<v Speaker 1>which are going to build up to that ideal, which

0:07:15.640 --> 0:07:18.440
<v Speaker 1>is that swarm of robotic craft and pitching a ride

0:07:18.440 --> 0:07:20.480
<v Speaker 1>on all of this. They're not developing a spacecraft. The

0:07:20.520 --> 0:07:23.559
<v Speaker 1>idea from the get go is let's hit your ride

0:07:23.560 --> 0:07:26.960
<v Speaker 1>on NASA spacecraft or whatever is available. We're not having

0:07:26.960 --> 0:07:29.440
<v Speaker 1>to develop as much technology on our own. We're bringing

0:07:29.480 --> 0:07:32.200
<v Speaker 1>in technology from this company, from this company, and we're

0:07:32.240 --> 0:07:35.600
<v Speaker 1>building something. We're building something, getting it out there and

0:07:35.680 --> 0:07:37.600
<v Speaker 1>completing these phases. And they're not going to mine it

0:07:37.680 --> 0:07:41.240
<v Speaker 1>right away. They want to tap it for volatiles, materials

0:07:41.280 --> 0:07:43.840
<v Speaker 1>with low bowling points such as water, oxygen, nitrogen, and

0:07:43.880 --> 0:07:48.080
<v Speaker 1>so on, which again critical supplies and space. And then again,

0:07:48.120 --> 0:07:49.960
<v Speaker 1>as you say, the last step then is to get

0:07:50.000 --> 0:07:53.600
<v Speaker 1>those precious minerals from the asteroids and bring them to Earth.

0:07:54.120 --> 0:07:56.760
<v Speaker 1>One way would be to launch equipment to a distant

0:07:56.800 --> 0:08:00.880
<v Speaker 1>asteroid already explored previously by a souped up based telescope.

0:08:01.360 --> 0:08:03.920
<v Speaker 1>Another might be to use a small spacecraft to bring

0:08:03.960 --> 0:08:07.080
<v Speaker 1>a smallish asteroid near the Earth, and a rock could

0:08:07.120 --> 0:08:09.320
<v Speaker 1>be brought into orbit around the Moon where it could

0:08:09.360 --> 0:08:12.200
<v Speaker 1>then be mined, or it could be both. A small

0:08:12.240 --> 0:08:15.120
<v Speaker 1>operation could start work while the asteroid is being towed

0:08:15.160 --> 0:08:18.080
<v Speaker 1>to Earth, getting a few years head start. It sounds

0:08:18.080 --> 0:08:19.640
<v Speaker 1>like a great plan there, because why I waste that

0:08:19.640 --> 0:08:21.760
<v Speaker 1>time that it's in transit and it could be harvesting

0:08:21.760 --> 0:08:23.160
<v Speaker 1>in along the way. All Right, we're gonna take a

0:08:23.240 --> 0:08:24.920
<v Speaker 1>quick break and then we're gonna get back to all this,

0:08:25.320 --> 0:08:32.360
<v Speaker 1>So hanging there for one second and we're back. A

0:08:32.440 --> 0:08:34.840
<v Speaker 1>lot of really great information on this came from a

0:08:34.880 --> 0:08:37.959
<v Speaker 1>blog called bat Astronomy by Discover magazine, So if you

0:08:37.960 --> 0:08:39.640
<v Speaker 1>guys want to check out a little bit more about this,

0:08:39.800 --> 0:08:42.440
<v Speaker 1>I believe there are several articles on this. But one

0:08:42.520 --> 0:08:44.959
<v Speaker 1>of the really interesting things that came out of bat

0:08:45.000 --> 0:08:49.440
<v Speaker 1>Astronomy is why exactly they're doing this? Because I thought, well,

0:08:49.679 --> 0:08:53.080
<v Speaker 1>obviously they're looking for some money here, right, that is

0:08:53.120 --> 0:08:56.240
<v Speaker 1>the first thing. But here's the deal. This could be

0:08:56.400 --> 0:08:58.560
<v Speaker 1>big money, right Trillian's, but this is not money that

0:08:58.559 --> 0:09:02.479
<v Speaker 1>they'll probably see these investors, as we'll see in their lifetime.

0:09:02.640 --> 0:09:05.920
<v Speaker 1>Is very possible because this is going to take a while,

0:09:06.040 --> 0:09:10.640
<v Speaker 1>and this really is much more about sustainable space exploration,

0:09:10.679 --> 0:09:12.920
<v Speaker 1>which I think is the coolest part about this. Yeah,

0:09:12.960 --> 0:09:15.440
<v Speaker 1>I mean there's some critics have pointed out that there

0:09:15.480 --> 0:09:19.240
<v Speaker 1>is a certain level of ego trip to this as well. Oh, absolutely,

0:09:19.920 --> 0:09:22.240
<v Speaker 1>it's very much involved. This is like Richard Branson. You

0:09:22.280 --> 0:09:25.040
<v Speaker 1>can take your suborbitall fight and put it in your

0:09:25.040 --> 0:09:27.480
<v Speaker 1>pipe and smoke it, because we are going to go

0:09:27.600 --> 0:09:32.199
<v Speaker 1>mine and asteroid, you know, in terms of like the

0:09:32.320 --> 0:09:34.520
<v Speaker 1>Branson does have the ice cube shaped like his own head,

0:09:34.600 --> 0:09:36.880
<v Speaker 1>and that's yeah, they're going to have to top that.

0:09:37.000 --> 0:09:38.720
<v Speaker 1>But one of the things I thought was amazing about

0:09:38.720 --> 0:09:41.080
<v Speaker 1>this is that they already have positive cash flow, or

0:09:41.120 --> 0:09:43.199
<v Speaker 1>so they claim. They're just working on getting Phase one

0:09:43.440 --> 0:09:46.440
<v Speaker 1>up and going, but they already have relationship with NASA,

0:09:46.480 --> 0:09:49.640
<v Speaker 1>they have money coming in. It is a functional company

0:09:49.679 --> 0:09:51.800
<v Speaker 1>at this point. Well, I mean the idea is that

0:09:51.840 --> 0:09:53.559
<v Speaker 1>it could be a win win for NASA too, because

0:09:53.600 --> 0:09:56.440
<v Speaker 1>they could then have access to materials and information. They

0:09:56.440 --> 0:09:59.959
<v Speaker 1>could sell some things back to NASA. It's really cool stuff.

0:10:00.080 --> 0:10:02.920
<v Speaker 1>The way that it's being planned out, obviously, it's very

0:10:03.040 --> 0:10:06.160
<v Speaker 1>like baby steps, and it's very careful in the way.

0:10:06.160 --> 0:10:08.319
<v Speaker 1>I mean, they realize this is a very difficult thing

0:10:08.360 --> 0:10:11.120
<v Speaker 1>to do. You just don't last an asteroid. Well, but

0:10:11.160 --> 0:10:14.800
<v Speaker 1>their argument is it's difficult, but it's not impossible. And

0:10:14.880 --> 0:10:16.760
<v Speaker 1>if you look at these pros and the cons are

0:10:16.800 --> 0:10:18.640
<v Speaker 1>kind of summed up in this as well. You have

0:10:18.720 --> 0:10:22.679
<v Speaker 1>these three steps. Step one finding asteroids very doable. We've

0:10:22.679 --> 0:10:24.800
<v Speaker 1>done it. It can be done, no doubt about it.

0:10:25.000 --> 0:10:28.319
<v Speaker 1>Step two, travel to an asteroid. It can be done.

0:10:28.360 --> 0:10:31.439
<v Speaker 1>We already mentioned we've done it before. That's that's definitely doable.

0:10:31.760 --> 0:10:35.600
<v Speaker 1>Step three, swarms of robots mining asteroids not so much.

0:10:35.840 --> 0:10:38.840
<v Speaker 1>That's a point. We're getting into a level of technology

0:10:38.840 --> 0:10:40.760
<v Speaker 1>that we haven't perfected, we haven't tested, we haven't worked

0:10:40.800 --> 0:10:42.680
<v Speaker 1>out all the kinks. That doesn't mean it's not doable.

0:10:42.760 --> 0:10:44.960
<v Speaker 1>It's very doable, but that is more of a leap

0:10:45.160 --> 0:10:47.600
<v Speaker 1>in technology. Now. By the time we get they get

0:10:47.640 --> 0:10:50.400
<v Speaker 1>to sphase three, you could argue that, well, the technology

0:10:50.400 --> 0:10:52.520
<v Speaker 1>will be there or the companies aligned with them will

0:10:52.520 --> 0:10:55.199
<v Speaker 1>have developed it. But some critics have pointed out that

0:10:55.200 --> 0:10:56.920
<v Speaker 1>that is a potential flaw on the plan, and that

0:10:56.960 --> 0:10:59.720
<v Speaker 1>there is a fairly large gap between the two series

0:10:59.720 --> 0:11:02.559
<v Speaker 1>and the three right time, money and technology right, Those

0:11:02.600 --> 0:11:04.760
<v Speaker 1>are some of the cons. Another con is that this

0:11:04.840 --> 0:11:08.199
<v Speaker 1>is not for planetary resources per se, but similar operations

0:11:08.240 --> 0:11:10.520
<v Speaker 1>like mining the Moon, where that the idea is not

0:11:10.600 --> 0:11:13.280
<v Speaker 1>the mining the asteroid, but the Moon could deplete moons

0:11:13.320 --> 0:11:17.080
<v Speaker 1>materials or moons materials. So that's not something that people

0:11:17.120 --> 0:11:20.480
<v Speaker 1>are totally excited about. But still it's a different animal

0:11:20.559 --> 0:11:23.320
<v Speaker 1>here pros we should talk about this. The future of

0:11:23.360 --> 0:11:27.040
<v Speaker 1>space exploration is not dead, at least from the perspective.

0:11:27.080 --> 0:11:29.720
<v Speaker 1>Here in the US, where we've shuttered so much of

0:11:29.960 --> 0:11:33.280
<v Speaker 1>our space exploration, the expense is not footed by the

0:11:33.280 --> 0:11:36.160
<v Speaker 1>public but by private companies. So that's good. And then

0:11:36.200 --> 0:11:40.080
<v Speaker 1>again NASA has access to materials and information. There's also

0:11:40.280 --> 0:11:43.120
<v Speaker 1>this idea that we could learn so much more, not

0:11:43.200 --> 0:11:47.120
<v Speaker 1>just about space but specifically asteroids. I could give us

0:11:47.160 --> 0:11:52.199
<v Speaker 1>insight into how to effectively divert an earth bound asteroid. Okay,

0:11:52.200 --> 0:11:54.040
<v Speaker 1>so we've talked about this. It's not just the movie

0:11:54.080 --> 0:11:57.640
<v Speaker 1>armagedon Ben Affleck saving the Earth. We don't need Ben

0:11:57.640 --> 0:12:02.680
<v Speaker 1>Affleck anymore. It's very possible that by observing asteroids and

0:12:02.880 --> 0:12:06.959
<v Speaker 1>by actually successfully mining them and spending time on them,

0:12:07.000 --> 0:12:09.800
<v Speaker 1>that we could figure out a way to divert them

0:12:09.920 --> 0:12:13.000
<v Speaker 1>from becoming meteorites crashing into us. Because, as we know

0:12:13.800 --> 0:12:16.280
<v Speaker 1>or suspect sixty five million years ago, this could have

0:12:16.640 --> 0:12:19.679
<v Speaker 1>very well been the reason for dinosaurs becoming extempt but

0:12:19.720 --> 0:12:22.199
<v Speaker 1>there were no dinosaur entrepreneurs with the habit and the

0:12:22.280 --> 0:12:26.120
<v Speaker 1>know how to turn an incoming asteroid into profits. It's true,

0:12:26.320 --> 0:12:30.160
<v Speaker 1>if only they had started studying filmmaking and possibly filming

0:12:30.280 --> 0:12:33.040
<v Speaker 1>the Titanic. Yeah, I'm thinking of like specifically, I'm imagining

0:12:33.080 --> 0:12:38.120
<v Speaker 1>of branson Osaurus a gat not that he's said he's involved.

0:12:38.440 --> 0:12:40.559
<v Speaker 1>I imagine that's the t rex I have to say,

0:12:40.679 --> 0:12:43.360
<v Speaker 1>rather than like a diplodochist or something. But this really

0:12:43.400 --> 0:12:45.240
<v Speaker 1>is a big concern. I mean, we talked about Armagon.

0:12:45.320 --> 0:12:47.920
<v Speaker 1>That seems ridiculous that you know, the movie Armagon. But

0:12:48.040 --> 0:12:51.559
<v Speaker 1>dozens of asteroids have been classified as potentially hazardous. But

0:12:51.640 --> 0:12:54.200
<v Speaker 1>the scientists who tracked them some of them become pretty

0:12:54.200 --> 0:12:56.720
<v Speaker 1>close to Earth. And I think it wasn't it in

0:12:56.800 --> 0:12:59.400
<v Speaker 1>Siberia in the early two thousand there was one that

0:12:59.480 --> 0:13:01.720
<v Speaker 1>crashed well, and if you go further back than that,

0:13:01.880 --> 0:13:05.600
<v Speaker 1>of course encountered the Tunguska event. Oh yeah, they're luckily

0:13:05.640 --> 0:13:08.199
<v Speaker 1>it hit in the middle of nowhere, but the same

0:13:08.280 --> 0:13:10.400
<v Speaker 1>kind of strike had it occurred in Europe would have

0:13:10.400 --> 0:13:13.280
<v Speaker 1>been disastrous. Yeah. I think I've mentioned before when in

0:13:13.320 --> 0:13:16.559
<v Speaker 1>fiction and movies and comic books, someone saves the world.

0:13:16.559 --> 0:13:21.720
<v Speaker 1>Every day saves the world, and in reality, about the

0:13:21.760 --> 0:13:24.440
<v Speaker 1>only thing that we have, the only effort that we

0:13:24.480 --> 0:13:27.760
<v Speaker 1>can definitely say this may save the world one day

0:13:27.800 --> 0:13:31.080
<v Speaker 1>in a very tangible manner are our near Earth object

0:13:31.120 --> 0:13:33.760
<v Speaker 1>protection efforts. The idea of let's figure out how to

0:13:33.800 --> 0:13:37.040
<v Speaker 1>divert an incoming near Earth objects before it actually hits

0:13:37.040 --> 0:13:39.320
<v Speaker 1>the planet. That's one of those situations where you can

0:13:39.360 --> 0:13:41.200
<v Speaker 1>definitely point to that and say, yes, if we developed

0:13:41.200 --> 0:13:43.720
<v Speaker 1>this technology and we get refined, we're tracking everything, and

0:13:43.720 --> 0:13:46.400
<v Speaker 1>then we have the ability to actually alter the course

0:13:46.600 --> 0:13:49.120
<v Speaker 1>of one that's headed towards us, that could save the

0:13:49.160 --> 0:13:52.040
<v Speaker 1>planet in a very very real and very meaningful way.

0:13:52.080 --> 0:13:54.320
<v Speaker 1>But then, of course it's the problem of asteroid miners

0:13:54.400 --> 0:13:56.960
<v Speaker 1>like hanging out mining and possibly getting chunked in the

0:13:56.960 --> 0:13:59.319
<v Speaker 1>head with a bit of space chunk. Well, that's a

0:13:59.320 --> 0:14:04.199
<v Speaker 1>whole another let's twine. So there you go asteroid mining,

0:14:04.200 --> 0:14:06.120
<v Speaker 1>and we'll obviously have much more information about in the

0:14:06.160 --> 0:14:08.880
<v Speaker 1>coming year, but is very exciting stuff. And what's going

0:14:08.920 --> 0:14:11.199
<v Speaker 1>on with our robot over there? Oh yes, the robot.

0:14:11.240 --> 0:14:12.720
<v Speaker 1>It's coming over here with some of the listener mail.

0:14:13.920 --> 0:14:15.319
<v Speaker 1>Before I get into the mail, I do want to

0:14:15.360 --> 0:14:17.360
<v Speaker 1>point out we had a few people writing about our

0:14:17.440 --> 0:14:20.680
<v Speaker 1>planetary scale episodes, and I think we kind of trip

0:14:20.720 --> 0:14:22.720
<v Speaker 1>over our words there and messed up a little bit

0:14:22.720 --> 0:14:25.360
<v Speaker 1>on the size of Earth versus the size of Venus.

0:14:25.640 --> 0:14:27.560
<v Speaker 1>I just want to point out that Venus has a

0:14:27.560 --> 0:14:31.320
<v Speaker 1>diameter that is about of Earth, so Earth is bigger

0:14:31.320 --> 0:14:34.240
<v Speaker 1>than Venus. Yeah. I think that we definitely messed up

0:14:34.240 --> 0:14:36.480
<v Speaker 1>when we switched those around. And that's what happens when

0:14:36.520 --> 0:14:38.840
<v Speaker 1>you start comparing things to peppercorns. And I think we

0:14:39.040 --> 0:14:42.479
<v Speaker 1>were specifically talking about like black peppercorns, firsts red peppercorns.

0:14:44.080 --> 0:14:49.720
<v Speaker 1>Learn your lesson there, pantry items, planetary sizes be warned.

0:14:50.080 --> 0:14:52.400
<v Speaker 1>Here's a quick listener mail from our listener, Peter Peter

0:14:52.440 --> 0:14:54.880
<v Speaker 1>Wright Sin says, Hey, Julian Robert, I heard your podcast

0:14:54.880 --> 0:14:56.680
<v Speaker 1>on Lucid Dreams a couple of weeks ago, and I

0:14:56.720 --> 0:14:59.520
<v Speaker 1>was completely mind blown. The fun wasn't actually intended, at

0:14:59.560 --> 0:15:01.960
<v Speaker 1>least to Lee. Reason being that in the beginning you

0:15:02.040 --> 0:15:04.800
<v Speaker 1>named all the types of dreams than Eden studied, and

0:15:04.840 --> 0:15:07.720
<v Speaker 1>briefly talked about a dream I have once in a while.

0:15:07.960 --> 0:15:10.840
<v Speaker 1>I barely remember my dreams, but these are memorable. It's

0:15:10.960 --> 0:15:14.360
<v Speaker 1>a dream type number six, and they're just gonna prefer

0:15:14.400 --> 0:15:17.480
<v Speaker 1>out the second. This would be dream sensations in which

0:15:17.480 --> 0:15:20.360
<v Speaker 1>there are no visions, no images, no events, not even

0:15:20.360 --> 0:15:22.600
<v Speaker 1>a word or a name. But during a long time

0:15:22.680 --> 0:15:25.640
<v Speaker 1>of deep sleep, the mind is continually occupied with one person,

0:15:25.760 --> 0:15:29.640
<v Speaker 1>one place, one remarkable event or even one abstract thought.

0:15:30.040 --> 0:15:31.400
<v Speaker 1>So then Peter went on to ask for a little

0:15:31.400 --> 0:15:33.240
<v Speaker 1>more detail on it, and we sent him some links.

0:15:33.240 --> 0:15:34.880
<v Speaker 1>But I found that very interesting because that was one

0:15:34.920 --> 0:15:36.960
<v Speaker 1>of the dream types where I didn't have any personal

0:15:36.960 --> 0:15:39.560
<v Speaker 1>experience with dreams of that kind, and I was very

0:15:39.560 --> 0:15:42.480
<v Speaker 1>curious if any of our listeners had so appreciate hearing

0:15:42.480 --> 0:15:44.600
<v Speaker 1>about it. If you have any thoughts you would like

0:15:44.600 --> 0:15:46.760
<v Speaker 1>to share with us, If you've had interesting dreams and

0:15:46.800 --> 0:15:48.720
<v Speaker 1>you have some thoughts on a Lucid Dreams episode, by

0:15:48.760 --> 0:15:50.560
<v Speaker 1>all means write us. And if you have any thoughts

0:15:50.560 --> 0:15:53.160
<v Speaker 1>about the future of asteroid mining and how that might

0:15:53.200 --> 0:15:54.840
<v Speaker 1>play out, but let us know about that as well.
