NASA’s Parker Solar Probe Is Unlocking the Sun’s Mysteries
"Just over a year ago NASA launched the parkers solar probe towards the Sun. It's an ambitious mission is going to get closer to our star than any spacecraft has ever done and to do so it has to withstand the Sun's intense heat and radiation in fact the probe job is literally going to touch the sun and take measurements inside the corona the Sun's outer atmosphere to help us better understand our star and the space weather it creates before it gets there though the probe has been slowly testing the waters with ever-closer approaches gathering. Data's does so and this week scientist a just released. The first batch of research from those fly buys one of the scientists getting their hands on this hot data. Was Dr Justin Casper. He's a professor of space. Sciences is an engineering at the University of Michigan Dodger. Casper welcome to quirks and quarks. It's great to be here. Thank you now before we get into your new findings Give us a quick overview of the mission in What are its goals and where we're at right now? Short so parker solar probe is the the largest helium physics mission. NASA has ever undertaken And it has a few main objectives one is to figure out why the Sun's Corona is about a thousand times hotter than the surface of the sun. So something really interesting is is happening that can take the six thousand degree visible yellow surface of the sun and produce a million degree corona glowing x rays ultraviolet light The second the thing is we want to figure out how the existence of that hot corona produces a really fast solar wind a stream of particles ions and electrons Iran's that travel out in the space away from the Sun at Millions of kilometers an hour now and to do this. You're actually going to the Senate's how how close are you going to get the way I like to think about. It is in units of the radius of our Sun so earth is about two hundred and fifteen solar radii away from the sun and to date the closest the spacecraft has ever gotten to the sun was seventy solar radii away from it What Parker solar probe does as it has Multiple orbits around on the Sun. where it plunges close to the sun and then pops back out again and then repeats Every few months and so far we've been closing within thirty five solar RADII but but over the next five years we're GONNA fly by the surface of Venus six times then each time we do that. Venus Bend our orbit closer and closer to the sun at the end of the mission will be about ten solar radii from the Sun. Wow well how is your probe able to survive getting that close to our star. This is very very difficult so at closest approach the spacecraft has a heat shield That reflects her absorbs about five megawatts of sunlight It's front gets up to about fifteen hundred degrees Celsius but it's back is only about three hundred degrees c wow that's astounding. Well tell me about the the latest data Ada even getting from the probe as it's on its way there. Yeah sure so. One has to do with how the silicone is being heated. Now when we've put spacecraft aft- into the solar wind in the past in her planetary space they see this constant stream of a special type of magnetic wave moving away from the sun. We call call those Alpha waves Think of it like Plucking Guitar string but the guitar string is a magnetic field line the magnetic field wiggles and the particles wiggle wiggle with them And those Al Fain waves carry a lot of energy So we were wondering when we got closer to the sunlight would just see more of these random Alvin fain waves may be there. There are a little larger amplitude. Could that possibly be the source of heating the Corona And what we found to our surprise is these he's Instead of just a random ocean of waves. That's maybe a little more intense. There were these huge rogue waves traveling by very coherent well-defined. Uh Spikes and the velocity in the changes in the magnetic field so just to describe the spacecraft would be coasting along through the solar wind And then suddenly within in seconds the speed of the flow jumped by about five hundred thousand kilometers an hour And we'd be sitting there in this weird jet of of flow flow And then just as suddenly a few seconds or hundreds of seconds later we pop out The other side. And we've left it. And when we analyze the data ada looks like these things are kind of s shaped kinks in the magnetic field. It's a it's a wave that so violent it's actually twisting the sun's magnetic field field around on itself so they're carrying an incredible amount of energy and this is really exciting because it could potentially explain the energy source that heats the corona. It does the data you have so far. Tell us anything about space weather. Since we're affected directly by that here on Earth. Yes absolutely so so. When it comes to heating the corona I'll give you a very specific example of this Coronal mass ejections are like violent eruptions of material from the Sun's Corona Rona. A A large mass ejection might involve an amount of mass Roughly equivalent to the water in Lake Michigan Going from rest to moving moving at a few million kilometers per second in just minutes That's incredible amount of energy expelled out in space. And if those hit earth they can you know disrupt Communications radar navigation electrical power. So he really wanted to be able to forecast whether or not a cme criminal mass ejection is GonNa hit Earth. The same way we're able to. With some reliability forecast weather hurricanes going to make landfall given place the speed of a wave in the sun's atmosphere as a function of the temperature of the atmosphere. So if we don't know how how things are you know. We're missing out on very fundamental things. Like just how faster waves going to to travel around Are we going to good job. Forecasting the path of interruption. If we if we don't even know how fast the waves are moving so this information is directly. Are you going to improve our our models in our simulations that we use to forecast based weather. Where's the pro right now? So the program now is actually pretty far away from the sun but it is headed towards Venus and on December. Twenty six. That's GONNA pass Just two thousand kilometers above the surface so Venus And that's going to deflect its orbit's so in January we can have our next perihelion down twenty eight solar radii instead of thirty five. What are you looking forward to most in this mission? There's a point that I really WanNa Cross with the spacecraft so these Al Fain waves that travel travel away from the Sun. There the fastest wave that moves through the sun's atmosphere And as you go away from the sun the solar wind speeds up and the speed eight of the Alpha waves drops down and at some point. The wind is escaping faster than an Alpha brain wave could travel back to the sun. The material truly disconnects from the sun on and becomes the solar wind. We call that point the AL fame point and if we get the spacecraft below the AL fame point will truly be in the extended atmosphere era of our sun. will be basically touching star for the first time I like to think about it And so I'm I'm very hopeful that between now and our final final orbits ten solar Radii we're going to cross elfin point And touch a star for the first time after Casper. Thank you very much for your time. My Pleasure
When Precision Counts
"I'm navigator. I compute trajectories a spacecraft figuring out where they're at and we're GONNA go. This is innovation now. Bringing bringing you stories behind the ideas that shave our future precise radio navigation using radio frequencies to determine position is vital to the success awesome deep space exploration missions. Here's Todd Haley Project Manager for NASA's deep space atomic clock to explain why precision should matters those signals traveled speed of light. That's three hundred thousand kilometers per second. So if you're off by a millisecond you'd be off by three hundred kilometers and measuring the distance so that spacecraft so it's really important that you have extremely precise timing on your signals de sac deep space time clock. I takes the UH technology we have in our ground atomic clocks packages it up into smalls based craft ready size device the mercury ions in the clock make it the most stable atomic clock ever flown and this kind of precision will ultimately help space navigators like todd pinpoint spacecraft's crafts position anywhere in space for innovation now.

Why is space so dark if its full of stars?
"Quite space. That's a deep question spaces dark because the universe is expanding. That's why spaces dark it's expanding and it's finite right because if the sight line through space ends on a star then that intensity of starlight would be the brightness rightness of that spot but most places you look do not land on a star so the expansion dilute starlight and not only that we don't live infinite universe because it for infinite eventually your sight line would land on a star if it did that the whole night sky would be ablaze with starlight. Oy Not Gaza. I'm GONNA play cool but you know stock to. Neil degrasse has Tyson's so it's a bag dale reason we see darkness instead of all starlet everywhere because the universe is expanding. The starlight is moving away from us and also because the universe is finite. If we look in a certain direction there might not be a star there but that's some big confusing really works your mind answer so i. I have a lot of fog questions. I have to get more answers. Neal was busy doing amazing astrophysics stuff so I went to visit my author author personal astrophysicist Heidi White the University of Toronto to help me see what's going on with all this light and the COSMO's all right now. Let's turn this on war on the roof of the astronomy building downtown Toronto in a warm pretty clear really windy night look. It looks like you're back to like fire laser. We're just firing up the telescope to check out some bright space objects that are close to US tidy that way. Let's move it a little bit and you see this. Let me move it up so you can pay it no friend he then that's Jupiter C. thanks yeah those are moons. We've it go. Heidi tells them not alone wondering white everything around my new. Pal Jupiter is so dark three hundred hundred years ago apparently there was this dude named wilhelm older who asked the same question you know the observing that we're doing right now is very similar to to the night sky observing that overdid over was doctor during the day and at night he turned like the roof of his house into an observatory and God at night just like we are and study what he you could see in the solar system so because older wondered why the sky was so dark. Apparently they named the question. After after calling it paradox basically the paradox that if the universe infinitely big infinitely old infinite general as they believed seventeen hundred then the whole sky should appear to be super bright all the time but it isn't and we know now oh boy Neil said the universe is an infinitely big. Neither is infinitely old. So why does that change the brightness of the Scott. What do you know about our universe and how long it's been around thirteen point five billion years like thirteen eighteen point six now close about thirteen point eight yeah so we know that our universe had a beginning and you know what that beginning was. Big Bang Bang release more just a very wet inflation just went really big. There was no big explosion or anything this kind of inflated like a balloon very quickly yeah. That's a really good analogy actually to to visualize the expansion space time one really good thing you can do is take a balloon and put a bunch of dots on it and then blow up the balloon start to cities. You put more air into it. Got Sort of what's happening is based on things are moving further and further away from one another but this is important in the context of understanding the answer to overs paradox because is what this means is that things haven't always been the way they look right now. The speed of light is fixed and what that means. Is that if we look look far enough away. What we're effectively doing is looking back in time in that way? Telescopes can actually be time machines because the most distant stars light in the universe hasn't had time to actually travel through space because it's been expanding to actually reach us the speed of light is three hundred thousand kilometers a second so the light from Jupiter takes thirty minutes to reach us here on earth so when we see it we're seeing Jupiter as thirty minutes ago and then there's Leiden University that is thirteen point eight billion light years away. This is the stuff made in the Big Bang guys so we can't see yet because we're not not that old yet. Maybe by the time high school be seeing light from a random star that I can't see today because it'll finally beginning to my eyes this but also maybe not 'cause well as the space time continue balloon just inflates inflates further. It'll just take even even longer for that light to reach your eyes.

The Supermoon explained
"As well as offering a change of seasons the much acre Knox's also brought with a circle superman that happened just four hours after the moment of equinox. The closest since March and the two thousand and it will be another eleven years twenty thirty before the two events will gain be less than a day apart. Well, just think of that we now closer to twenty thirty what want to the thousand a by the way, this was also the third and final superman for twenty nine chain. The term ship moon was invented back in nineteen seventy nine by an astrology not on astronomy for those unfamiliar with the difference between the two and astronomers a person to study space in the cosmos, using the scientific method to learn about the universe and astrologer is a person uses inaccurate positions. Constellations planets and other celestial bodies at different times in order to tell people about the character would have predict the future has never ever ever ever ever ever. Been any scientific evidence. Supporting any of the claims made by strategy and its success depends exclusively on the Gulf ability of people now back to the science on average the moon orbits about three hundred eighty four thousand four hundred kilometers from earth. But the moon's orbit around the earth isn't a perfect circle. It's slightly elliptical. Meaning one part of the orbit will be closer to the earth. Bet. Three hundred fifty seven thousand kilometers is parody. And the other part of the oil, but will be further away around four hundred and six thousand kilometres apogee, the differences about five percent closer or further away on average the exact distances of perishing apogee, also very other factors such as whether the lunar orbits long axes pointed towards the sun. Also, the moon's Ogle extremes a greatest between November and February when the earth, oh, but places the planet and its moon close into the sun, you say earth orbit itself is also elliptical by that two percent. And they will the sun's gravitational influence is greatest during these months, technically. These would be Jane full moons but trend to its east terms like what use the description of super moon to describe any Newell full moon with a ninety degrees of parody syncing opportunity. Nassar's now adopted this term as a means of educating the public about astronomy twenty nineteen will be an excellent year to look to the sky and enjoy the spectacular view of earth's nearest neighbor. The moon fifty years ago, we witnessed one of humankind's most, remarkable achievements. When we first step foot on the dusty surface of the moon. All for man. By ugly. As NASA continue celebrating the fiftieth anniversary of the Apollo program. The year is opening with a number of opportunities to marvel at earth's original satellite, three super moons, and a total lunar eclipse in the span of three months. So what is it that makes a super moon super start with size? The moon orbits around the earth in a slightly oval shape at its furthest point away from us known as the apogee it's about two hundred fifty thousand miles or four hundred thousand kilometers from earth when it's closest to us. It's parody. The moon is about two hundred twenty thousand miles or three hundred fifty thousand kilometers away when the moon is full at or near its parody. It is considered a super moon and can appear up to fourteen percent larger and thirty percent brighter than it apogee. Those distances however are changing as the moon is slowly. Shifting away from earth how slowly approximately two inches or five centimeters annually a billion years from now the moon will take about thirty one and a half days to orbit the earth. Instead of today's twenty seven point three days. In the meantime, this year's first superman of the year occurred on January twenty first and also featured a total eclipse, the second occurred on February nineteenth and sky watchers. Another chance on March twenty first well, super moons. Total lunar eclipses are marvels to behold. A question rises fifty years after humankind's first steps on the moon. Does it hold anymore secrets for NASA? Scientists Noah petro project, scientists for the lunar reconnaissance orbiter or El aro at nestles Goddard Space Flight center says there are many unanswered questions about the moon. For example, we are still attempting to understand how the moon evolved to its current state. The moon has occupied space near earth for its entire four and a half billion year history. Keeping record of the impacts that have scarred on its surface over time. This record of anxious impacts is largely erased from the earth due to win water in plate tectonics analysis of Apollo samples shows that there was a period of intense impact cratering on the moon early in the history of the solar system and therefore on the earlier as well observations from L our show now in its ninth year of orbiting the moon or helping us piece together this history people say shoulda moons, especially big in brunt compare to regular full moons, but will a can be around fourteen percent lodge and thirty percent broader, you really wouldn't notice the difference unless someone told you and even then any size difference perceptions. You do have will be more likely GTO imagination in reality, you'd really need proper non-legal equipment to Mitch the difference. And remember the full moon always looks lodge and Bryant when it's near the horizon and a fake none as men allusion. The other important point member is. That Superman's not all that uncommon. They usually current groups of three roughly about every thirteen months in eighteen days. In other words, roughly every fourteenth full moon will be superman now one consequence of superman that should be noticeable involves ocean tides many factors influence title heights at a given location that they usually highest something that a spring tides during full moons or new moons when the earth sun and moon are all aligned so a parody moon being big plus than average should result in a slightly higher high tide.
What Is Light?
"Light. In addition to being a bright, Patrick, sunshine on your window. Sill is a metaphor for enlightenment and exploration, which is a bit paradoxical for phenomenon that even after thousands of years of inquiries and endless experiments. Scientists still can't quite explain is it a particle or wave or both or neither do we need a new word for it. Your eyes tell you a lot about the way light behaves. It travels so fast that seems instantaneous about one hundred eighty six thousand miles or three thousand kilometers per second. It blazes through air and space and laser like straight lines. But it also bounces reflects and refraction, and when it interacts with the right medium like a camera lens, it make her we know that it's made up of tiny units that we call photons, and we know that the term waves can describe its movements. But neither of these words really encompass lights auditees in ancient times. The Greeks used philosophy to attempt to address lights wide range. Of behaviors perhaps they thought light is actually composed of little bits of stuff that bounce to and fro the idea never really caught on then in the sixteen hundreds French philosopher Rene Descartes became convinced that light was essentially a wave one that moved through a mysterious substance that he called platinum Isaac Newton thought that light was a particle, but he was at a loss for a way to explain many of its properties. Like the way it refracted and could be split by prison from a single beam of white light into a rainbow of many colors of light. This was largely before the rise of empirical studies in science wherein, we attempt to answer questions about the world around us by designing experiments that demonstrate well how stuff works back in the day. Science was a matter of philosophy people coming up with about how stuff works and basically arguing about the ideas merit to be fair. Our modern microscopes computers and other equipment help just for example, lights behavior becomes more evident, depending on where you're observing it in the vacuum of space. Ace light zips along at the aforementioned one hundred eighty six thousand miles or three hundred thousand kilometers per second. But point a beam of light at a very dense bit a matter say a diamond, and it can slow to only around seventy seven thousand miles or one hundred twenty four thousand kilometers per second much easier to observe relatively to try to explain in. These are modern times. What light is let's I remember some science basics waves are not a thing or substance. They're a property of thing. A wave is a compressing and stretching of a particular medium, a like an ocean wave that drives toward the shore or the ripple spreads out across the surface of a pond when you toss in Iraq, you can see the waves with your eyes feel them with your body. And sometimes when a sound wave happens in the air, you can hear them with your ears particles on the other hand are not quite so easy to define particle can be a tiny bit of matter. A matter broken down into its smallest and most basic units water, for example, is made up of countless party. Guls particles that are affected by waves. What's really happening when you watch a wave in the ocean or ripple in a pond is that each particle or molecule in this case of water is being moved and thus the medium of the ocean or pond is being compressed and stretched in sequence and we see waves, but light as experiments have proven also consists of particles that we call photons the behave like waves. Let's unpack that there was a famous nineteenth century double slit experiment in which researchers beamed light through two slits and observed the way the light struck a screen behind the slits what they saw was that the streams of light affected each other like two hands splashing water in the same sink as if they were waves interfering with one another. But then in the twentieth century scientists began their pioneering explorations into subatomic particles. Like neutrons electrons, Albert Einstein wondered what would happen? If you emitted light one photon at a time in the double slit experiment. What scientists saw dumb found? Did them the single photons went individually through the slits, but the way that they struck the screen over time showed the same interference pattern that occurred with full-scale beams of light streaming through both slits this behavior can't be explained by the physics. We use to describe particles and waves in the macro world around us, it's in the realm of quantum mechanics. The physics theories that describe what goes on at the very smallest subatomic levels, and which we humans still don't really understand. So ultimately, if you want to answer the question, what is light you could call it both a particle and wave and you'd be correct. But as for fully explaining why and how it works. We're still working on

"hundred thousand kilometers" Discussed on Quirks and Quarks
"We'll take an enormous amount of stuff that will have to send four hundred thousand kilometers from the earth at fantastic expense unless we figure out how to make stuff on the moon. That's the problem. Researchers at the European Space Agency had been wrestling with and their new solution is a clever idea for making all sorts of things from a resort. That's plentiful on the moon lunar dirt. Dr advent Mataya an advanced manufacturing engineer at the European Space Agency and his team have demonstrated that they can fabricate small parts from screws to gears using simulated regular or moon dust, and some modern technology to Mikhail welcome to cork in Cork's. Thank you very much for having me. What is the technology? That you're using to make small parts out of moon dust so to make this mode baths. We are actually mixing the moon the moon dust with the binder kind of glue which react to light. So when it's exposed to light it hardens. We can harden the binder glue the grains of frigging layer by layer to three D print the objects that we that we are manufacturing three D printing. Tell me about that. So three D printing is just the principle of building a three dimensional object layer by layer. And at the end of the process, you get your three d object. Now, you're doing this using moon dust what exactly is moon dust? So Moon-dust is not very different from the sun that you have on earth silicone oxide the defending side beat the fire on site and so on which are mixed. And of course, it's very difficult to get the real stuff from. The moon. We only have some from the Apollo missions. So what we do is that we create simulants. So we signed that we find him most of the time volcanic send. And then we make sure that we have seen. La gimme Cal compositions similar grant size distribution as as what we would find on the on the moon. And that's what we used to do our three D printing exudes now when you talk about using glue, and the you're not actually melting this are you just gluing it together, literally. That's that's correct. So this most crews, and guess it's based on using a binder. So you keep the grains of of the as they are. And you just applying glue. So you you're not melting the the sun the dust, which would require high amount of energy. Now, we have looked into other techniques where we actually use heat to fuse to partially fused the grants together using Casandra. Centrating Salah light or some of the people are using microwave. So that's another. They can use a binder or glue. All you use a bit of heat to fuse the grants together. How precise is the process very precise? And to our knowledge is the most precise you we have a chief so far. So we can reach details, which are all the other of fifty microns which is one twentieth of a millimeter so about half of your hair. And that's the curious that we can reach right now. So the product that you end up with if I was to hold say, I don't know screw that you made in Mahan. How how tough would it be would it would it be have kind of a rough service to it? It's very smooth face because of the accuracy that we get we can build very fine and very smooth surfaces in terms of toughness. It's pretty much like Jeremy objects. He would find that to make on earth with regular regular processes. So that's how it would feel like it would be something like a copy Cup. Yes. I was expecting it to feel something like sandstone that you might be able to grind it down. Just with your fingers, you're saying, it's pretty tough pretty tough..
Kenya launches first coastguard
"Coastline is one thousand kilometers long. And yet until recently it didn't have a coastguard maritime security has been the job of the navy. But now the president of hurricane iota has launched the first coastguard service this one big problem though, it only has one boat. Here's the tell us Moore's Robert folks defensive tour of the London Evening Standard wrote. There are many problems possessing that part of the coast from piracy and people in jugs trafficking to illegal fishing, and I wondered if you could just give us a bit more detail on on the piracy aspect. It doesn't seem as bad now as it was in its peak in two thousand eleven Parisy has been confronted. I've heard say that surly dealt with by about national force by led largely by the EU. But it's actually burden-sharing between the EU beta and on. The whole it's been pretty successful. Because one of the things that became apparent after this dreadful business. Extended. It'd be guide for several years is that the the brevity of the life of the parrots that they they they were very very short lived. Indeed, the Mr. bags always the so-called logical, Mr. beg, but they were making the money and back and forth from east Africa to west Africa and also to south East Asia, but I can straight that sort of airy Parisy hasn't gone away. But it is interesting in the way that you have flagged up this new force. The new coast guard for spring stood up by president Kennedy at its prime role, actually isn't counter piracy, it is counter narcotics. But above all counter illegal fishing, and the president said in the inaugural speech for their full said that really, you know, we're letting too much getaway one hundred billion dollars. It's a very modest beginning. But the two very definitely related because legal fishing. Of course, has meant that loss of livelihood for many of those people living along the coast, and some of those people that are going into piracy. Yes, I think it's very interesting that almost this is philosophical gesture of the part of the canyons very, very bodice beginnings. It's interesting if the declaration I've been trolling through the notes and the president's page, I'm not quite sure of the specific numbers that very very small numbers for very difficult in job at the navy's only about two thousand below in personnel for coast as you say one hundred thousand kilometers, very difficult and very important one. And as far as I can make out most of the coast guard personnel again to be joined drawn from the paramilitary police that forty is seen as the new ship. The new vessel the door at is that surveillance facile. It is actually gathering intellige-. Silence about the kind of very kind very matter you've been toying piracy illegal operations, penetration.

Collide, so often we actually see galaxies merging and passing free one. Another like to ghosts. Yes. Absolutely. It happens all the time because gravity is the most dominant force in the university pulls together is pulling our galaxy tools Andromeda galaxy which is unable four hundred thousand kilometers per hour. When when they do collide in three point eight billion years, or so we'll have this incredible cacophony of light and color in the sky the spiral of both galaxies will be ripped apart. And then wrap back around the sky this incredible. I say it's like the embrace of cosmic octopus because these spiral arms, which is wrap around us sky. There will be thousands of new stars brighter than the current stars created in sky, and they'll be just light and color everywhere. The won't be darkness and a few stars. They'll be just dominant the host will be dominated by light. So it'd be like a negative image of the current. That's right. It'll be more. What than black? That's right say it's like to the headlights of a car coming towards us the whole sky in the night. Nighttime. We'll be we'll be light.

"But that's that's doable. We we did do it. So clearly it's do. Lable. Location giving someone to Mars getting anything to Mars takes a lot more time. Now, part of that is because the distance between earth and Mars is not constant. And the reason for that is that you know both planets are going around the sun, right? But they're going at different speeds and their orbits are different sizes. So there are times when earth and Mars are aligned and they are about close as they possibly can be. And there are other times where earth is on one side of the sun and Mars is on the other side of the sun, and they're about as far apart as they possibly can be. So the distance varies dramatically at the closest earth and Mars are about thirty three million nine hundred thousand miles apart or fifty four million six hundred thousand kilometers. So to compare again to the moon, the moon was two hundred thirty eight thousand nine hundred. Miles away Mars thirty three million nine hundred thousand miles away. So that's not a day trip way further and that that its closest at its furthest away Mars is about two hundred forty. Nine million one hundred sixty thousand miles away or four hundred one million kilometers away. So if you're gonna make a mission to Mars of any kind. Then you need to do a lot of thinking about it and planning beforehand because you need to decide, okay, what what are we going to send their? We're going to send a Rover men. How how much is that gonna way? Well, it's going to about this much how much you know rocket to do. We need to throw at it. Right. Okay. So you got your, got your rocketed, and you're. Just basically think like some sort of nineteen eighties side. Scrolling video game rocketed. I'm going to write that. Okay. And you're over, you know what? You know what you wanted to. Do you know how to get there? You start having to think about all sorts of other stuff. Okay. Well, so how much gravity does Mars have? How much difference in the wait is they're going to be once this this Rover gets there. How are you know how much atmospheric interference it's going to be there. Okay. So you're going to have to plan how long it's gonna take for you to shoot this thing in its base and get to Mars and how it's gonna stop when it gets there. Oh, and then you have to take into account if you know roughly how long it's gonna take. Where are the two planets going to be? Yeah, you have to figure out. Backwards from there and get they're going to be at their closest here..
