Latest / Made of Stars / NASA Is Watching Two Asteroids
Transcript
- 0:00Warning. The following podcast contains an entertaining look at astronomy, physics, and
- 0:04space news throughout the known universe. Listeners have been known to learn about astronomical
- 0:08phenomenon, the scientific method, and expanded vocabulary to include terms like quasar,
- 0:12asterism, and uranus. Listen, that's your own risk. Go ahead.
- 0:22When made of stars, made them stars made sizes. When made of stars,
- 0:33you could be from high they would New Mexicomus. Where are stars?
- 0:43When we are made of stars? I'm West Carol, joined by my good
- 0:58friend doctor Sean Cruising from Columbus State Universities, Coca Cola Space Science Center.
- 1:03Morning Shawn, Hey, we's good to be here today. Let's talk about
- 1:07asteroids. We have stories from time to time where we'll say, oh,
- 1:11we're getting kind of a near miss from an asteroid, or we'll have a
- 1:15story that will make a big splash on you know, it'll make it to
- 1:19the USA Today's of the media world and they'll go, oh, my gosh,
- 1:23there's an asteroid. It's coming right for us and we're all gonna die.
- 1:27Please buy our newspaper or whatever they say. I don't know some version
- 1:30of that that they say. Click on this site is probably more like it.
- 1:36And sometimes there's elements of not necessarily we're all gonna die, but there's
- 1:41elements of, you know, we have to be a little concerned. And
- 1:45you and I have talked about the fact that we had Dart. We've had
- 1:49situations like even the Osiris Rex mission. So, but Dart especially being able
- 1:59to you know, maybe throw something off course, change direction or whatever.
- 2:02They've successfully done that. So there's a real valid reason to be concerned about
- 2:07something possibly coming our way. Ask the dinosaurs. Oh wait, so we
- 2:15have one that is I guess the one that is at the top of the
- 2:20If there was a most wanted list right now, maybe observers would say this
- 2:24is the one that's at the top of their list, the one that they're
- 2:29the most concerned about. Am I describing this thing correctly? Yes, So
- 2:37before we jump too deep into that, let's just say this. There are
- 2:40a lot of asteroids in our neighborhood. And the article I'm going to refer
- 2:46to today and have you go check it out when you get a chance,
- 2:51is on a website called IFLScience dot com. It stands for I Really like
- 2:58science, Gonna be honest with you. This is the first time that I've
- 3:02ever gone to that site before. So I'm just saying, well, if
- 3:08you really like science, go to IFL science dot com. Yeah. I
- 3:14see lots of their stories. I see lots of their posts in my feed
- 3:17and in social media. I've just never clicked on it before. But I'm
- 3:22glad to know there's some actual science going on there. Yeah. I mean,
- 3:27the one thing they can say is they really love science. The name
- 3:30isn't even what's deterred me from it. I just, you know, I
- 3:34just looked at the name and went, I don't know, is is this
- 3:38a real site? But I'm glad to know that they've got some real science
- 3:40there and that they really really love it. An interesting Yeah, it's an
- 3:45interesting story. You know, it's an interesting story from them. I'm going
- 3:47to quote them to say a couple of things. First of all, they
- 3:51said, quote on the website IFL science dot com. In the article about
- 3:55the potentially hazard as asteroids that NASA is most concerned about, they say,
- 3:59no need to worry, NASA has it all under control. Now that's their
- 4:03words, not mine. I'm not really sure what they meant by that.
- 4:08We do know that NASA is tracking them very carefully, and so we do
- 4:14know, as you mentioned, that NASA has deployed, shall we say,
- 4:17a couple of different types of spacecraft to do some mitigating measures. One of
- 4:25those was the Dart spacecraft. Hey, what happens if we just sock an
- 4:28asteroid in the eye as hard as we can with a spaceship That proved has
- 4:31some pretty potent results, quite honestly. The second one was the the o
- 4:36Cyrus REX mission, and we're going to get back and talk about of Cyrus
- 4:40Rex in just a moment, But another quote from IFLScience dot com is this,
- 4:46we highly recommend heading to NASA's Eyes on Asteroid's website and selecting their closest
- 4:53approach. Now, friends, I actually did this, and so I had
- 4:58not been to NASA's Eyes on on Asteroids website. And basically what it is,
- 5:02it's a plot of all of the asteroids that are in the greater vicinity
- 5:09of Earth's orbit around the Sun. And so you can watch and see first
- 5:13of all, how many of them there are, which that visualization is already
- 5:17very impressive. The second thing you can see is how honestly, how close
- 5:24some of them already are to the Earth. And there are literally swarms of
- 5:29asteroids moving around the Sun right in the neighborhood of Earth. Now, the
- 5:35visualization you're going to see on this website, nothing's to scale. They're just
- 5:40kind of giving you points that are markers to show you how close in vicinity
- 5:46to the Earth relative to its position around the Sun things are. So they're
- 5:49not to scale, so it makes it all look a lot closer than it
- 5:51really is. But just knowing the sheer number of asteroids in the immediate vicinity
- 5:58of Earth, many of which are far large enough to be able to do
- 6:02some very serious regional damage. This according to the NASA website itself, it's
- 6:11a little sobering, quite frankly. So, so maybe the best part to
- 6:15me is not necessarily which asteroid NASA is most concerned about, just the fact
- 6:20that there are so many of them that we should all be concerned about.
- 6:25And so, yeah, check out NASA's Eyes on Asteroid's website, and you
- 6:30know, just pop that in the Google machine. It'll take you there.
- 6:32Check it out. It's pretty impressive. Now, when they say don't worry,
- 6:39NASA has it all under control, I'll say this, and I mean,
- 6:42I'm gonna I'm gonna take our military aside from what I'm about to say,
- 6:46because obviously that's different. But of the government agencies that I would go,
- 6:51man, I think that they might have something under control, I kind
- 6:57of feel like NASA would be at the top of that list for me.
- 7:00So I do feel a certain amount of maybe I'm naive, I don't know,
- 7:03but I feel like when they say NASA's got it under control, they
- 7:08probably have it under control. There are a lot of really high quality people
- 7:14that work for the National Aeronautics and Space Administration, smart people, smart people
- 7:17who can figure things out. And when you take a lot of those smart
- 7:21people and you put them in teams and they work together under certain protocols,
- 7:27that makes an even more refined machine. So you're right, I kind of
- 7:31agree with you. NASA is the one of the few government agencies that I'm
- 7:35just going to say, yeah, I trust them to do their job.
- 7:40In a pinch. Yeah, I mean, maybe I shouldn't give them my
- 7:42complete trust, but I feel pretty confident that they've got an eye on these
- 7:46things, and they're you know, prepared for something. Well, they're keeping
- 7:53their eye on what are called neo's NEEO near Earth objects, and these are
- 8:01in particular, they're watching the ones that are four hundred and sixty feet across
- 8:05or larger, because these are the ones that could cause regional, if not
- 8:09larger amounts of devastation on the Earth if they hit. And so they're looking
- 8:16they're working with astrophysicists to predict how far in the future these objects might come
- 8:22close enough to our part of the Solar system that they would cause a real
- 8:26problem for Earth. In other words, very minor changes to their orbits around
- 8:31the Sun could bring them in contact with the Earth. That's a that's a
- 8:37true neo, that's a true near Earth object. That's a potentially hazardous asteroid.
- 8:41Friends, and so the site is tracking them. Now. The question
- 8:46of the headline though, is you know which one of they most worried about.
- 8:48Well, it kind of came down to two, honestly. And there
- 8:52are the asteroids. Benuch is going to make a very close pass in about
- 8:58fifty years, and then there's the Apophous asteroid. We're just going to make
- 9:03a very close pass in twenty twenty nine actually, and so that's not very
- 9:09far away, that's a mere five years away, and so it's good to
- 9:11know your enemy. And it's very interesting that these are two of the most
- 9:16concerning asteroids because these are also two of the asteroids that have been visited by
- 9:22the Osiris Rex spacecraft friends. So so NASA is already gathering data on these
- 9:30two now I say have been visited. Benu has been sampled by o Cyrus
- 9:33Rex. We've already dropped some skin samples from that asteroid out there in the
- 9:37desert of the southwestern United States, and that baby's in the lab being analyzed
- 9:43right now. And then the Apopous asteroid is to be visited biro Cyrus Rex.
- 9:48It's on its way out to that asteroid to take data of that particular
- 9:52object so we can understand the physical nature of these two asteroids better. So
- 9:58when we read that phrase NASA has it all under control, Well, I
- 10:01would say two things. Number one, they're tracking these asteroids very carefully.
- 10:07Number two, they're sending space missions Lychosyrus Rex out there to figure out what
- 10:11these asteroids are like, so we can understand their physical properties and characteristics better.
- 10:18In case number three, we have to hit it with a dart spacecraft,
- 10:20punch it right in the eye. So I feel like it should be
- 10:24noted that if you have a middle school age kid and I can speak to
- 10:31the boys, I don't know it may be the case also with girls.
- 10:33But I know that Luke has come home from school talking about Apophice and like
- 10:39the kids talking about I don't know that they said it by name, but
- 10:43they're like, oh, in twenty twenty nine, we're gonna die. There's
- 10:45an asteroid coming at us. And they've gotten into that hype about it and
- 10:48talked about it, and you know, they talk about it. So if
- 10:52your kid comes home and is talking about that, that's the one that they're
- 10:56talking about. And just know NASA has a eye on it, and you
- 11:01can assure them with that, and also know that technically its current orbital projection
- 11:09doesn't have it does not have it coming so close to the Earth that it
- 11:13actually is going to impact. Something would have to change the trajectory of the
- 11:18orbit of that asteroid. But this is one of the reasons why we want
- 11:20to know what it's made out of, because here's what can happen. It
- 11:24can get close enough to the Sun where if it has any kind of volatiles
- 11:28on the inside of that asteroid, in other words, things like carbon dioxide,
- 11:33things like methane and ammonia. When it has those kinds of objects on
- 11:37the materials on the inside and it gets close to the Sun and heats up,
- 11:41you can have some jetting kind of effects, some outgassing that could push
- 11:46the asteroid off its known trajectory and put it on a course, well,
- 11:52an unpredicted course. That's why if you know it's coming close, you definitely
- 11:56want to know what it's made out of to understand whether or not there's a
- 12:00possibility for one of these outgassing events that might change its orbit slightly. And
- 12:05that should have been the first part of my clarification, because I told Luke,
- 12:07no, this thing's not really heading for us. It's just kind of,
- 12:11you know, explaining to them that there's a there's a hype that goes
- 12:13with it, and one, it's not really coming for us. In two,
- 12:18if it does, there, they've got time. They're aware of it,
- 12:20they're looking into it. I mean, they got time to figure out
- 12:24what to do with it should there become an issue. Let's talk about this
- 12:28new star that could be showing up here very soon. Now. This is
- 12:33a cool story. You can read about it on NASA dot gov. But
- 12:37there are a number of stories out there about this one. There's an object
- 12:41out there called T. Coronai Borealis. T. Corona Borealis happens to be
- 12:46a star system. It's in the constellation of Corona Borealis, which stands which
- 12:52means the Northern Crown. That's the name of the constellation. Well, the
- 12:56interesting thing is that astronomers have been watching Ta Corona Borealis for some large number
- 13:03of years. That's because back in the year nineteen forty six, we actually
- 13:07saw a very bright outburst from this particular star. That star in the sky
- 13:13got a whole lot brighter for a short period of time, and astronomers identified
- 13:18that thing as actually an object called a nova. Now what is a nova?
- 13:22Well, a nova is this? A nova happens when two stars are
- 13:26dancing together. These stars are both old stars. One of the stars has
- 13:33reached the end of its lifetime and it's actually gone through a phase where it's
- 13:37lost all of its outer layers. That star has become a white dwarf.
- 13:41So a white dwarf is the nuclear core of a star that used to be
- 13:46like the sun, but then again it aged, it lost its outer layers
- 13:50and now you just have the core engine of that star proceeding. It's in
- 13:54close orbit around another star that's still in the red giant phase, which means
- 14:00it's a star again like the Sun, reaching the end of its life,
- 14:05but is still in the process of losing its outer layers. Well, what
- 14:09you have is you have one really big star with some loose gases on the
- 14:13outside. You have one really small star that used to be the core of
- 14:16a much larger star. They're orbiting close to one another. They're a binary
- 14:20star system, and that small star is feeding off the loose material on the
- 14:26outside of the big star. There's an accretion disc around that red giant star.
- 14:31The white dwarf is feeding off that accretion disc. It's building up material,
- 14:35and then eventually it gets to a point where all that material on the
- 14:39surface of that white dwarf, that newly collected material, ignites, It detonates,
- 14:46and so it explodes into a bright outburst. You basically create the conditions
- 14:50on the outside of that white dwarf for nuclear fusion to take place, something
- 14:56very similar to what happens inside the core of our Sun today, and so
- 15:00you have a brief outburst of nuclear fusion on the outside layer of this white
- 15:03dwarf and it gets very very bright for a short period of time, and
- 15:07so that is what's known as a nova event. All right, let's go
- 15:11back to T. Corona borealis. Astronomers have been carefully monitoring the behavior of
- 15:18that variable star. It's varying because it's eating that material off its neighbor,
- 15:22the Red Giant, and it looks like it's going to be in a pattern
- 15:26very similar to what preceded the nineteen forty six eruption, so similar in fact,
- 15:35that astronomers are predicting that it could go anytime. So what will that
- 15:39mean, Well, that will mean this. If this Ta Coronai borealis star
- 15:43goes into a nova phase, it's going to be bright enough in our sky
- 15:48to be able to be seen with the unaided eye. We call that the
- 15:50naked eye. You can walk out and literally see it in the sky without
- 15:54a telescope, which means that somewhat unremarkable. Constantly of Corona Borealis, the
- 16:00Northern Crown, which is up during the summer, by the way, handily
- 16:04enough, it means it's going to have a brand new star in it that
- 16:08may be brighter than all the rest of the stars in the constellation. This
- 16:12makes it well worth walking out and checking out in the nighttime sky. Here's
- 16:17what I would here's what I would suggest. Don't wait till this thing goes
- 16:21nova. Go find Corona Borealis now. There are a variety of websites that
- 16:27you can use to acquire a star map of constellations in the evening sky.
- 16:33Skymaps dot Com happens to be one of my favorites. Go out and find
- 16:38a star map that shows your Corona Borealis, so you know what it looks
- 16:42like now, so that way you can recognize the new star when it shows
- 16:48up. Now, astronomers are actually predicting September so early fall for the star
- 16:56to go supernow, or to the star to go nova rather not super nov
- 17:00that's a different phenomenon. So being watching for this star, you know now
- 17:04throughout the summer, throughout the next few months, probably going to go the
- 17:08rest of the way in September. That's at least if it follows the same
- 17:14patterns it did in nineteen forty six, but it really could go at any
- 17:18time. So here's your two steps. Number one, go out and find
- 17:21Corona Boreality. You recognize it, and then number two just begin to watch
- 17:25that night after night and also kind of follow the space media. They're going
- 17:30to tell you the status of that particular object. But you could see a
- 17:33brand new star in the sky, a really cool nova phenomenon by September early
- 17:37fall of twenty twenty four. Part of what is always fascinating about this and
- 17:41anytime we're looking at something that in this I guess about three thousand light years
- 17:45away what we're talking about. So we're talking about all of this happening now.
- 17:48They're observing it happening now. Obviously this happened a long time ago,
- 17:53but we're just now able to see it, and it's fascinating we're talking about
- 17:57it in present time like we're seeing. It's like having a friend who you
- 18:03know, you you find out that they've got a newborn, but the newborn
- 18:07is now fifteen and you're like, oh, well, I just met the
- 18:08kid. He's fifteen. He's not really a newborn at all, but to
- 18:11you, they're they're new to you, right. It is it is that
- 18:17exactly, and you know it's it's an object which even though it's far away
- 18:22in terms of you know, it's a lot of light years away, it's
- 18:26still relatively close in our own part of the Milky Way, which is why
- 18:30it will be bright enough to be seen with the unaided I when it goes
- 18:33nova. So so even though yeah, you're looking anytime you're looking deep off
- 18:37into space, you're looking back in time because of the finite light travel speed.
- 18:44So that's always something that's kind of fascinating. When you look up at
- 18:47different objects in the sky, you're really looking at time capsules from some much
- 18:51earlier time, and depending on how far away they are, they could be
- 18:55really old time capsules. So this is it's an interesting component to the store.
- 19:00But yeah, so be watching for for the star that's far away but
- 19:03yet still close enough to get bright bright in our sky, bright enough to
- 19:07be seen at night with the unaided eye, in the constellation of Corona Borealis.
- 19:12Let's talk about the slowest spinning neutron star ever. Yeah, so we
- 19:22usually talked about the biggest, the brightest, the fastest. We rarely talk
- 19:26about the slowest of anything in space. But you gotta talk. I mean,
- 19:29if you're gonna talk about the fastest, sometimes you gotta occasionally acknowledge the
- 19:33slowest. I mean, you know, it's you just have to do that
- 19:38every every every pitcher can't be throwing you know, one hundred and three miles
- 19:42an hour fastballs. You know, you got to appreciate the good change up.
- 19:45Guys. It's it's hard to remember who ran the slowest time in the
- 19:52one hundred meters in the Olympics the year that Usain Bolton, right, I
- 19:57mean everybody remembers Usain bolt because because that was amazing. He sent in new
- 20:02Olympic records fastest human being ever alive. But yet there was somebody that same
- 20:07Olympic season that ran the slowest hundred meters and I can't tell you who that
- 20:12was. I can't either. I don't think they're getting the proper respect that
- 20:17they deserve. It should be getting some sort of acknowledgment. But the only
- 20:22I will say that the only reason they were slowest is because I personally didn't
- 20:25run in that one hundred meters. That's fair. You know. I've joked
- 20:29before. I've played golf at Callaway Gardens on the course there before, and
- 20:33I think I'm the worst person to ever play there. I feel like I
- 20:37would challenge anyone to tell me that they're not as bad as I am,
- 20:41so I think I hold that record. So that's kind of like this,
- 20:45right, I mean it's sort of like this. So so here it is
- 20:48friends the slowest rotating neutron star in history. That's what's been discovered. So
- 20:56astronomers have found more than three thousand radio emitting neutron stars, and most of
- 21:00them spin within seconds to milliseconds. That's how long it takes them to spin
- 21:07around one time. Let's talk about this for a second. First of all
- 21:10story Universe today dot com. You can check it out there in back.
- 21:14The next couple of stories have come from that very great website, Universe today
- 21:18dot com. So what is a neutron star? Well, a neutron star
- 21:22is this. It's similar to the white dwarf in the sense that it's the
- 21:26it's the thermal nuclear engine of a once great star, in fact, even
- 21:30bigger than our own son. But the star went supernova some time ago,
- 21:37and as the outer layers of that star were ripped away by the supernova explosion,
- 21:42what was once that fire breathing thermo nuclear fusion core of that star collapsed
- 21:51and very similar to how another Olympic reference, when an ice skater pulls their
- 21:56arms in during a spin move, they speed up. This is due to
- 22:03something called the conservation of anger momentum in physics. The pulling the arms in
- 22:07makes their overall radius smaller, but anger momentum must be conserved, so their
- 22:14rate of rotation spin speeds up, and that way it can conserve anger momentum.
- 22:18Anyway, something along those lines, well, imagine something the size of
- 22:22a star's core being suddenly shrunk down to something smaller than the city limits of
- 22:30Columbus, Georgia. And I know there's a whole city county government thing there's
- 22:33you go to say, well, what's the city limits? Okay, yeah,
- 22:37anyway, it's it's smaller than the downtown area of most mid sized cities.
- 22:41How about that. And so, in the process of taking that very
- 22:45large object and having its own gravity squeeze it down to something that's very small,
- 22:52it shrunk its orbital radius, it's radius of spin, and therefore the
- 23:00momentum had to be conserved, so it speeds up. So these objects tend
- 23:03to spin very very fast. You know, even hundreds or thousands of times
- 23:11per second is not unusual as a rotation rate. All right, So then
- 23:18if you find one that's spinning lazily at once every hour roughly what every fifty
- 23:26four minutes. Well, that doesn't really fit the model of what we just
- 23:33described on how neutron stars are formed in the first place. So something,
- 23:40according to astronomers, something likely had to slow this rotation down in kind of
- 23:45a non standard way. And one of the things that astronomers quickly thought of
- 23:48as well, what if it has a really strong magnetic field, and then
- 23:53it was some force of magnetism interacting with the plasma around that star that caused
- 24:00it to slow down. It was like a drag, a magnetic drag on
- 24:03that object. So when they see these very slow spinning neutron stars, astronomers
- 24:11have begun to hypothesize that they could also have very strong magnetic fields. Now,
- 24:17this is an interesting idea. More research needs to be done. The
- 24:21astronomical community has not come to a consensus on why you would have slow period
- 24:26neutron stars. But remember, friends, they've never found one that's slow before
- 24:30a fifty four minute rotation period, which is a very long time to spin
- 24:34around. So they're in the realm of new physics. They're trying to come
- 24:38up with new answers, and we'll keep it on our eye on it.
- 24:41But yeah, in the meantime, check out the story on Universe today dot
- 24:45com the slowest spinning neutron star ever. Coming up after a quick break,
- 24:49a cosmonaut has reached a thousand days cumulative in space. We'll talk about that
- 24:56next. All right, we're just talking about Hussain Bolt and his uh,
- 25:18you know, incredible speed and then the person who was you know, dead
- 25:22last. We don't know who that was. Uh, and I'm curious,
- 25:26do we know who the person is that spent the least amount of time and
- 25:30spent now I'm just kidding. We have a new record for most time in
- 25:33space cumulatively, and that's a Russian cosmonaut who has now broken the one thousand
- 25:38day mark. Yeah. I mean, his name could be Shatner, but
- 25:44that's what I was thinking. It could be shattered, could be straight hand,
- 25:48straight hand might have been probably a little heavier. He might not have
- 25:51gotten quite as high. I don't know. It's it's entirely those are two
- 25:55really good candidates, so perhaps one of them anyway, Yeah, so uh,
- 26:03let's talk about Commander Oleg Cononenko. Oleg Cononenko a cosmonaut has surpassed the
- 26:10one thousand days of cumulative space time in his career. It's a one thousand
- 26:15day mark. He is the first person to ever reach one thousand cumulative days
- 26:19in space. So it's a it's a pretty cool record. Uh. He
- 26:23just passed that on Wednesday of last week, and so he's still up there.
- 26:30He's still adding days. Who knows if he'll run into a Frank Rubio
- 26:33type situation and have to stay much much longer than he thought. I mean
- 26:38that could be hundreds of days more potentially for Oleg Cononenko. So he's actually
- 26:44scheduled to come back down in September of this year. He's coming back down
- 26:49with Nikolai Chubb, who is not related to Nick Chubb cosmonaut. Say what's
- 26:57he doing enough to? I mean, I say he's not related to Nick
- 27:03Chubb. I don't know that. I don't think the name makes the assumptions
- 27:07there. I think it's missing a B. I don't know. It seems
- 27:11anyway, I'm making some assumptions about American football players and Russian cosmonauts that perhaps
- 27:17I shouldn't jump to. I'll retract that statement. To my knowledge, he's
- 27:22not related to Nick Chubb. But but Nikolaichubb is is is a cosmonaut.
- 27:27He's up there right now with old Leg Cononenco and Tracy Dyson among other astronauts.
- 27:33Uh, they're up there on the International Space Station. Tracy Dyson and
- 27:37nickel Laichubb not to be confused with Nick Chubb, will be coming back in
- 27:41September. So at that time he will have added some cumulative days in space
- 27:47to his record. This is not talking about Nick Chubb, by the way,
- 27:48We're talking about Oldlake Conanenko. He will added some days to the cumulative
- 27:53time there, and so he'll be returning with an even larger record for some
- 27:57future astronaut or a cosmonaut to beat. By the way, the previous record
- 28:03holder was also not a member of the Cleveland Browns, but another cosmonaut named
- 28:08Gannadi Padalka. So Gannadi Padalka had eight hundred and seventy eight days in space
- 28:15that was surpassed now by hold A Cononenko with a thousand days in space,
- 28:21and Cononenko's meter is still running. I'm curious, and im probably asking a
- 28:26question you don't specifically know the answer to. But I'm just this is just
- 28:30me, you know, doing my job on the show, is just asking
- 28:33the questions. But I guess it just I kind of wonder there has to
- 28:38have been an astronaut or several that have just said, send me up there
- 28:44and just let me die up there. Just just leave me up there.
- 28:47I won't come home. I don't have a reason to come home whatever,
- 28:51I'll just stay put. There have to have been volunteers for that, and
- 28:55obviously they don't think it's in their best interest, but at some point,
- 29:00I mean, maybe that can happen. Right Well, I mean, look,
- 29:06let's talk a little bit about colonization, because we're in an era where
- 29:11our Federal Space Agency is telling us that they're going to colonize the Moon,
- 29:18and we have other groups who say they're going to colonize Mars. And when
- 29:25that begins to happen, I mean the notion of you know, maybe people
- 29:30in Europe several hundred years ago, a few hundred years ago, colonizing a
- 29:37new world, you know, a different continent. I don't think that they
- 29:41planned on coming back, right, And so we're not in that mindset yet.
- 29:47We're still dipping our toe into spaceflight, but certainly what you've just described
- 29:52is going to be something that's going to happen where somebody's going to say,
- 29:56hey, send me on a one way trip. I mean, we have
- 30:00already had people who have volunteered for one way trips to Mars, by the
- 30:06way, and so that's not something that is you know, in the realm
- 30:11of fantasy or science fiction or whatever. Certainly is those things, but we've
- 30:15had actual people say, yes, I would go. I would volunteer for
- 30:19a one way trip to space, to go to be the first person on
- 30:22Mars, or even among the first people on Mars. You wouldn't have to
- 30:27bring me back. I would live out my days there. So yeah,
- 30:32these kinds of things have already occurred. I don't really know if I have
- 30:36any official references for NASA astronauts who volunteered that, but certainly, you know,
- 30:41humankind being what it is, those people are out there, and as
- 30:47we begin the process of colonizing other worlds, we're going to need some of
- 30:51those kinds of people, right, You really are going to need people who
- 30:53are going to say I'm going to go and I'm just going to go in
- 30:56Definitely, maybe I'll come back, maybe I won't, But my trip is
- 31:02it doesn't have a return date. I'm gonna go and be there for some
- 31:06unknown, indefinite period of time. I feel like I want to say it
- 31:10was a buzz Aldron, but I may be misattributing the quote, but it
- 31:14was buzz Aldron who had the line about six feet under on Mars is like
- 31:18the next great destination. Yeah, I can't remember if that was Buzz or
- 31:25not. I have to admit, sorry, I don't remember that quote.
- 31:26I have heard that quote before. Yeah, I feel like it was him,
- 31:30but whoever said it. I mean it's profound and it's true obviously,
- 31:33and it relates to what we're talking about. So yeah, I just feel
- 31:37like at some point there would be some some astronaut who would and obviously,
- 31:41you know this is a cosmonaut who has no problem with being up there,
- 31:45so at some point you would think there would be And maybe China gets the
- 31:48space station up and says we're just going to leave somebody up there and they're
- 31:52going to stay put and just ride it on out. I don't know.
- 31:55Yeah, I mean these kinds of things sound very inhumane to the people who
- 31:59would never want to do that, and that's fair that's fine, But there
- 32:06have been a number of people in human history and even in the history of
- 32:09our own country, who said, yeah, sure, I'll go out west
- 32:15and I'll help settle what Arizona yep, right, yep. And they didn't.
- 32:22They didn't make it back to the east coast of the US, right,
- 32:25they didn't. They didn't make it back to family and friends on the
- 32:30other side of the appellation. How many how many people died of dysentery on
- 32:35the Oregon Trail. I mean, we know it's not just a computer game,
- 32:39but not nearly as many people as died in the computer game. I
- 32:43think if you had if you took all the cumulive people who died in the
- 32:45Oregon Trail computer game, it's far greater than the actual number of people who
- 32:50died on the Oregon Trail. But that's that's a subject for a different show.
- 32:52So, but the notion is that we as human beings are explorers,
- 32:57and we we have people among us who were perfectly willing to commit what might
- 33:02to the rest of us seem to be an unreasonable amount of dedication to pursuing
- 33:09these kinds of efforts to explore, to investigate, and to find new worlds
- 33:15and new new areas, right, and so so yeah, sometimes I think
- 33:20we get a little overconcerned with the choices of others if people choose to do
- 33:24these things. I think, honestly, the human species needs these pioneers,
- 33:31right, we really do to help push us forward. Because the timid among
- 33:36us, which by the way, I'm one of those the timid among us,
- 33:38would never do it, and so we would. We just wouldn't have
- 33:42those growth opportunities. But yet brave souls decided, you know, I am
- 33:45going to go to Alaska and I am going to look for gold in the
- 33:50Yukon or whatever. Right, I'm just trying to think of times where there
- 33:53were you know, I am going to jump on the ship with Shackleton and
- 33:58see if we can get to the South Pole. Why. I know I
- 34:00might never come back, but yet I'm willing to go do that, right,
- 34:05So yeah, I think it's a it's an important characteristic of human bravery
- 34:08quite frankly, and just a driving need to explore that pushes our species forward.
- 34:16And so yeah, we maybe we shouldn't be so provincial in our thinking
- 34:22about those people who are willing to take these great steps and jump in and
- 34:25do these amazing things. Let's talk about what's going on at Columba State University's
- 34:30co Cola Space Science Center. We're in the really truly into June into summer
- 34:37now so and we often reference the it comes with the cost of admission air
- 34:42conditioning that you guys have there in the facility, But it's more than just
- 34:45a place to cool down. It's a way to keep kids' brains engage this
- 34:49during the summer and get them away from screens. Just for not that you
- 34:52guys don't have some screens in there, they're just different kinds of screens.
- 34:57Yeah, we try to keep our screens entertaining an edge occasional both, but
- 35:00we also understand that if you want to skip all the screens in the Space
- 35:04Science Center because your children have been looking at screens far too much, there's
- 35:07still plenty of other things to do. Friends. They can drive some Mars
- 35:12rovers for instance. They can see some meteorites that have fallen from space.
- 35:16They can check out artifacts components of the Space Shuttle that have actually flown missions
- 35:22down or space. They can have very tactle experiences in our Space Shuttle Odyssey
- 35:28and in our flight simulators and so these are all great things. They can
- 35:30feed aliens in our guzzle vortex, or at least would be aliens or comic
- 35:36book aliens with our guzzle vortex machine. So these are all fun things for
- 35:39the kids to do friends. You know, as if you've been listening to
- 35:43the podcast, you might have heard Wes and I chat about the fact that
- 35:45I've been doing a kind of coming and going set of trips to Houston,
- 35:50Texas. This is because I have a new addition to my family. I
- 35:52have a new grandson. I was in Houston again today and we've visited the
- 35:58Houston Museum of Natural History. It's a great thing to do, just take
- 36:02the family and go to a cool museum because there's all kinds of fun things
- 36:07inside the museum that not they're entertaining, sure, but they start so many
- 36:12great conversations with your kids, and your kids will ask you all kinds of
- 36:15questions that maybe you don't even know the answers to, but it's okay because
- 36:20you can begin the conversations that spark the curiosity that have your children wanting to
- 36:25learn. That's what the Coca Cola Space Science Center in Columbus, Georgia is
- 36:30dedicated to to having those kinds of experiences with you and your family that inspire
- 36:35kids to want to learn about space, about space exploration, and about their
- 36:39universe and their world around their friends. So check out the website www dot
