Dialogue: 0,0:00:09.37,0:00:12.20,Default,,0000,0000,0000,,So, you're thinking of moving to Mars.
Dialogue: 0,0:00:12.20,0:00:15.98,Default,,0000,0000,0000,,Have you picked out a spot \Nfor your new home?
Dialogue: 0,0:00:15.98,0:00:19.16,Default,,0000,0000,0000,,No? Well, I'm here to help.
Dialogue: 0,0:00:19.16,0:00:20.49,Default,,0000,0000,0000,,First things first,
Dialogue: 0,0:00:20.49,0:00:23.88,Default,,0000,0000,0000,,here are some of the things\Nyou'll need to bring to The Red Planet:
Dialogue: 0,0:00:23.88,0:00:29.32,Default,,0000,0000,0000,,a high tolerance for cold, \Nloneliness, and radiation;
Dialogue: 0,0:00:29.32,0:00:32.94,Default,,0000,0000,0000,,a lifetime supply \Nof breathable air and food;
Dialogue: 0,0:00:32.94,0:00:35.32,Default,,0000,0000,0000,,a multibillion dollar spaceship;
Dialogue: 0,0:00:35.32,0:00:37.93,Default,,0000,0000,0000,,a desire to just get away from it all;
Dialogue: 0,0:00:37.93,0:00:39.37,Default,,0000,0000,0000,,and water.
Dialogue: 0,0:00:39.37,0:00:43.64,Default,,0000,0000,0000,,You're definitely going to need water.
Dialogue: 0,0:00:43.64,0:00:46.18,Default,,0000,0000,0000,,So what sort of real estate\Nare you looking for?
Dialogue: 0,0:00:46.18,0:00:50.05,Default,,0000,0000,0000,,How about a mansion in the maze-like\NNoctis Labyrinthus?
Dialogue: 0,0:00:50.05,0:00:52.69,Default,,0000,0000,0000,,A hideaway in the Happy Face Crater?
Dialogue: 0,0:00:52.69,0:00:56.22,Default,,0000,0000,0000,,A fortress on the Face Mesa?
Dialogue: 0,0:00:56.22,0:00:57.96,Default,,0000,0000,0000,,An oceanview?
Dialogue: 0,0:00:57.96,0:01:00.79,Default,,0000,0000,0000,,Uh, bad news on the last one.
Dialogue: 0,0:01:00.79,0:01:04.31,Default,,0000,0000,0000,,You're about 4 billion years late.
Dialogue: 0,0:01:04.31,0:01:07.95,Default,,0000,0000,0000,,We're pretty sure that Mars\Nused to have oceans, lakes, rivers,
Dialogue: 0,0:01:07.95,0:01:09.97,Default,,0000,0000,0000,,the whole package.
Dialogue: 0,0:01:09.97,0:01:13.70,Default,,0000,0000,0000,,But over time, almost all of it\Nfroze beneath the surface,
Dialogue: 0,0:01:13.70,0:01:16.58,Default,,0000,0000,0000,,or evaporated off into space.
Dialogue: 0,0:01:16.58,0:01:19.18,Default,,0000,0000,0000,,There's probably still some\Ntrapped beneath
Dialogue: 0,0:01:19.18,0:01:25.06,Default,,0000,0000,0000,,the seasonally expanding and contracting\Ncarbon dioxide ice caps, though.
Dialogue: 0,0:01:25.06,0:01:29.34,Default,,0000,0000,0000,,So what might Mars look like today\Nif it had surface water?
Dialogue: 0,0:01:29.34,0:01:32.13,Default,,0000,0000,0000,,That, of course, depends\Non how much we're talking about,
Dialogue: 0,0:01:32.13,0:01:34.57,Default,,0000,0000,0000,,but maybe something like this.
Dialogue: 0,0:01:34.57,0:01:39.06,Default,,0000,0000,0000,,The relatively flat northern hemisphere\Nis below the average elevation,
Dialogue: 0,0:01:39.06,0:01:41.67,Default,,0000,0000,0000,,so it would become one giant ocean,
Dialogue: 0,0:01:41.67,0:01:43.56,Default,,0000,0000,0000,,while the crater-ridden \Nsouthern hemisphere
Dialogue: 0,0:01:43.56,0:01:47.09,Default,,0000,0000,0000,,would stay mostly high and dry.
Dialogue: 0,0:01:47.09,0:01:50.50,Default,,0000,0000,0000,,That difference between hemispheres\Nis a bit bizarre,
Dialogue: 0,0:01:50.50,0:01:52.65,Default,,0000,0000,0000,,and we don't know why it's like that.
Dialogue: 0,0:01:52.65,0:01:55.10,Default,,0000,0000,0000,,The southern half is probably\Nmuch older,
Dialogue: 0,0:01:55.10,0:01:57.43,Default,,0000,0000,0000,,judging by features \Nlike the number of craters,
Dialogue: 0,0:01:57.43,0:02:02.76,Default,,0000,0000,0000,,and the evidence of increased\Nvolcanic activity in the north.
Dialogue: 0,0:02:02.76,0:02:04.14,Default,,0000,0000,0000,,Okay, so who knows?
Dialogue: 0,0:02:04.14,0:02:06.84,Default,,0000,0000,0000,,Maybe one day Mars will have oceans again,
Dialogue: 0,0:02:06.84,0:02:11.75,Default,,0000,0000,0000,,but for now, what we've got is essentially\None giant dusty desert.
Dialogue: 0,0:02:11.75,0:02:14.61,Default,,0000,0000,0000,,In fact, it's similar enough \Nto deserts on Earth,
Dialogue: 0,0:02:14.61,0:02:19.24,Default,,0000,0000,0000,,that we've been able to learn a great deal\Nabout Mars on our home planet.
Dialogue: 0,0:02:19.24,0:02:22.32,Default,,0000,0000,0000,,For instance, Martian sand dunes\Nform and behave
Dialogue: 0,0:02:22.32,0:02:24.66,Default,,0000,0000,0000,,similarly to our sand dunes,
Dialogue: 0,0:02:24.66,0:02:28.01,Default,,0000,0000,0000,,though the Martian versions \Noften grow twice as large
Dialogue: 0,0:02:28.01,0:02:33.31,Default,,0000,0000,0000,,thanks to a gravitational pull\Nthat's about a third as strong as ours.
Dialogue: 0,0:02:33.31,0:02:36.23,Default,,0000,0000,0000,,And Mars has some features\Nyou won't see on Earth,
Dialogue: 0,0:02:36.23,0:02:41.36,Default,,0000,0000,0000,,like tars, which are crestless\Nsand dunes up to fifteen meters tall,
Dialogue: 0,0:02:41.36,0:02:44.80,Default,,0000,0000,0000,,whose formations \Nwe have yet to understand.
Dialogue: 0,0:02:44.80,0:02:46.06,Default,,0000,0000,0000,,You're probably wondering,
Dialogue: 0,0:02:46.06,0:02:48.82,Default,,0000,0000,0000,,"What do you get when you\Ncombine a planet-wide desert
Dialogue: 0,0:02:48.82,0:02:51.06,Default,,0000,0000,0000,,with an atmosphere that, like ours,
Dialogue: 0,0:02:51.06,0:02:56.49,Default,,0000,0000,0000,,is subject to wind-generating\Npressure differentials, dust storms?"
Dialogue: 0,0:02:56.49,0:02:59.42,Default,,0000,0000,0000,,These will be your main weather hazards\Non the Red Planet.
Dialogue: 0,0:02:59.42,0:03:02.24,Default,,0000,0000,0000,,They play a large part \Nin making the planet red
Dialogue: 0,0:03:02.24,0:03:07.64,Default,,0000,0000,0000,,by distributing rusted iron particles\Nacross the surface and into the air.
Dialogue: 0,0:03:07.64,0:03:09.92,Default,,0000,0000,0000,,Thanks to the low gravity\Nand lack of moisture,
Dialogue: 0,0:03:09.92,0:03:14.96,Default,,0000,0000,0000,,these dust storms can last for months\Nand cover the planet.
Dialogue: 0,0:03:14.96,0:03:19.78,Default,,0000,0000,0000,,So, you might want to build your home\Nas high as possible.
Dialogue: 0,0:03:19.78,0:03:21.48,Default,,0000,0000,0000,,Well, look no further.
Dialogue: 0,0:03:21.48,0:03:27.20,Default,,0000,0000,0000,,This is Olympus Mons,\Nthe largest volcano in the Solar System.
Dialogue: 0,0:03:27.20,0:03:29.32,Default,,0000,0000,0000,,Even if Mars had a breathable atmosphere,
Dialogue: 0,0:03:29.32,0:03:34.56,Default,,0000,0000,0000,,you'd find the views from \Nthe 25 kilometer summit breathtaking.
Dialogue: 0,0:03:34.56,0:03:36.16,Default,,0000,0000,0000,,Or are volcanos not your thing?
Dialogue: 0,0:03:36.16,0:03:41.92,Default,,0000,0000,0000,,Then how about Valles Marineris,\Nthe largest canyon in the Solar System?
Dialogue: 0,0:03:41.92,0:03:44.06,Default,,0000,0000,0000,,It's so wide that from one side,
Dialogue: 0,0:03:44.06,0:03:48.18,Default,,0000,0000,0000,,the opposite rim would be below\Nthe curve of the horizon.
Dialogue: 0,0:03:48.18,0:03:53.69,Default,,0000,0000,0000,,Still, you'll catch some spectacular\Nblue sunsets in the normally red sky,
Dialogue: 0,0:03:53.69,0:03:57.14,Default,,0000,0000,0000,,which gets its color from the dust\Nabsorbing most of the blue light,
Dialogue: 0,0:03:57.14,0:04:01.63,Default,,0000,0000,0000,,and the way sunlight is scattered\Nby the atmosphere.
Dialogue: 0,0:04:01.63,0:04:06.48,Default,,0000,0000,0000,,Have you got spirit, curiosity,\Nor are you just looking for opportunity?
Dialogue: 0,0:04:06.48,0:04:10.91,Default,,0000,0000,0000,,Then stop stalling\Nand make the move to Mars today.
Dialogue: 0,0:04:10.91,0:04:14.22,Default,,0000,0000,0000,,Mars: Redder than Ever.
