Could we actually live on Mars? - Mari Foroutan

Da li bismo zaista mogli živeti na Marsu? - Meri Forotan (Mari Foroutan)

Prevodilac: Tijana Mihajlović Lektor: Mile Živković

So, you're thinking of moving to Mars.

Znači, razmišljate da se preselite na Mars.

Have you picked out a spot for your new home?

Da li ste izabrali mesto za svoj novi dom?

No? Well, I'm here to help.

Ne? Pa, ovde sam da vam pomognem.

First things first,

Krenimo od početka.

here are some of the things you'll need to bring to The Red Planet:

Evo nekih stvari koje treba da ponesete na Crvenu planetu:

a high tolerance for cold, loneliness, and radiation;

visoka tolerancija na hladnoću, usamljenost i radijaciju,

a lifetime supply of breathable air and food;

doživotne zalihe vazduha za disanje i hrane,

a multibillion dollar spaceship;

svemirski brod u vrednosti od nekoliko milijardi dolara,

a desire to just get away from it all;

želju da pobegnete od svega

and water.

i vodu.

You're definitely going to need water.

Voda će vam definitivno trebati.

So what sort of real estate are you looking for?

Pa, kakvu vrstu nekretnine tražite?

How about a mansion in the maze-like Noctis Labyrinthus?

Šta kažete na vilu u Noktisu Labirintusu koji je nalik na lavirint?

A hideaway in the Happy Face Crater?

Pribežište u Krateru srećnog lika?

A fortress on the Face Mesa?

Tvrđavu na Mesi Lice?

An oceanview?

Pogled na okean?

Uh, bad news on the last one.

Uh, loše vesti vezane za ovo poslednje.

You're about 4 billion years late.

Zakasnili ste oko 4 milijardi godina.

We're pretty sure that Mars used to have oceans, lakes, rivers,

Prilično smo sigurni da je Mars imao okeane, jezera, reke -

the whole package.

ceo paket,

But over time, almost all of it froze beneath the surface,

ali vremenom se skoro sve to smrznulo ispod površine,

or evaporated off into space.

ili isparilo u svemir.

There's probably still some trapped beneath

Ipak, verovatno postoji nešto vode zarobljene

the seasonally expanding and contracting carbon dioxide ice caps, though.

ispod ledenih kapa od ugljen dioksida koje se periodično šire i skupljaju.

So what might Mars look like today if it had surface water?

Pa, kako bi Mars izgledao danas da ima vode na površini?

That, of course, depends on how much we're talking about,

To, naravno, zavisi od toga o kolikoj količini vode pričamo,

but maybe something like this.

ali možda bi ličio na nešto poput ovog.

The relatively flat northern hemisphere is below the average elevation,

Relativno ravna severna hemisfera je ispod prosečnog nivoa,

so it would become one giant ocean,

pa bi postala ogroman okean,

while the crater-ridden southern hemisphere

dok bi južna hemisfera koja je prenatrpana kraterima

would stay mostly high and dry.

uglavnom ostala iznad nivoa mora i suva.

That difference between hemispheres is a bit bizarre,

Ta razlika između hemisfera je malo bizarna,

and we don't know why it's like that.

a ne znamo zbog čega je to tako.

The southern half is probably much older,

Južna polovina je verovatno mnogo starija,

judging by features like the number of craters,

sudeći po osobinama kao što je broj kratera,

and the evidence of increased volcanic activity in the north.

kao i dokazima povećane vulkanske aktivnosti na severu.

Okay, so who knows?

Okej, ko zna?

Maybe one day Mars will have oceans again,

Možda će jednoga dana Mars opet imati okean,

but for now, what we've got is essentially one giant dusty desert.

ali za sada u suštini imamo jednu ogromnu prašnjavu pustinju.

In fact, it's similar enough to deserts on Earth,

U stvari, slična je pustinjama na Zemlji u tolikoj meri

that we've been able to learn a great deal about Mars on our home planet.

da smo mogli da saznamo mnogo o Marsu na našoj izvornoj planeti.

For instance, Martian sand dunes form and behave

Na primer, peščane dine na Marsu formiraju se i ponašaju

similarly to our sand dunes,

slično našim peščanim dinama,

though the Martian versions often grow twice as large

iako marsovske verzije često porastu dva puta više

zahvaljujući gravitaciji čija jačina iznosi

thanks to a gravitational pull that's about a third as strong as ours.

oko trećinu jačine naše gravitacije.

And Mars has some features you won't see on Earth,

Mars ima i neke osobine koje nećete sresti na Zemlji,

like tars, which are crestless sand dunes up to fifteen meters tall,

kao što su TAR-ovi, peščane dine bez vrhova visoke i do 15 metara,

whose formations we have yet to understand.

čije formiranje tek treba da shvatimo.

You're probably wondering,

Verovatno se pitate:

"What do you get when you combine a planet-wide desert

„Šta dobijate kada ukombinujete pustinju širom planete

with an atmosphere that, like ours,

sa atmosferom koja, kao i naša,

is subject to wind-generating pressure differentials, dust storms?"

podleže razlikama u pritisku koje stvaraju vetrovi - peščanim olujama?”

These will be your main weather hazards on the Red Planet.

To bi bile naše glavne vremenske neprilike na Crvenoj planeti.

They play a large part in making the planet red

One igraju veoma važnu ulogu u tome što je planeta crvena,

by distributing rusted iron particles across the surface and into the air.

kroz širenje zarđalih čestica gvožđa površinom i vazduhom.

Thanks to the low gravity and lack of moisture,

Zahvaljujući slaboj gravitaciji i nedostatku vlage,

these dust storms can last for months and cover the planet.

ove peščane oluje mogu trajati mesecima i pokriti celu planetu.

So, you might want to build your home as high as possible.

Tako, možda ćete poželeti da izgradite svoj dom što više.

Well, look no further.

Ne tražite dalje.

This is Olympus Mons, the largest volcano in the Solar System.

Ovo je Olimpus Mons, najveći vulkan u Sunčevom sistemu.

Čak i da Mars ima atmosferu koja dozvoljava disanje,

Even if Mars had a breathable atmosphere,

you'd find the views from the 25 kilometer summit breathtaking.

otkrili biste da pogled sa vrha na visini od 25 kilometara oduzima dah.

Or are volcanos not your thing?

Možda vam se vulkani ne sviđaju?

Then how about Valles Marineris, the largest canyon in the Solar System?

Šta onda kažete na Vales Marineris, najveći kanjon u Sunčevom sistemu?

It's so wide that from one side,

Toliko je širok da je, gledajući sa jedne strane,

the opposite rim would be below the curve of the horizon.

suprotni kraj iza linije horizonta.

Still, you'll catch some spectacular blue sunsets in the normally red sky,

Ipak, ulovili biste spektakularne plave zalaske sunca

na obično crvenom nebu,

which gets its color from the dust absorbing most of the blue light,

koje dobija svoju boju od prašine koja upija većinu plave boje,

and the way sunlight is scattered by the atmosphere.

kao i od načina na koji atmosfera rasejava Sunčevu svetlost.

Have you got spirit, curiosity, or are you just looking for opportunity?

Raspoloženi ste, znatiželjni, ili samo tražite priliku?

Then stop stalling and make the move to Mars today.

Onda prestanite da odugovlačite i napravite korak ka Marsu još danas.

Mars: Redder than Ever.

Mars: crveniji nego ikada.
