  • Congratulations,

  • you've taken the seven-month-long journey

  • and have finally landed on Mars.

  • And it turns out, you're the first person.

  • Better start cleaning the place up,

  • and getting it ready for human colonization.

  • A trip to Mars might happen much sooner than you think.

  • NASA is hoping for it to be as soon as 2033.

  • Think about that.

  • The first person on Mars might be watching this video right now.

  • Hello, future Martian!

  • And NASA may not be the first to get there.

  • There are plenty of other space companies trying to get to Mars around the same time.

  • Similar to what we saw in the 1960s with the Moon,

  • it's very likely we'll see another space race,

  • only to Mars this time.

  • But getting there is the boring part, now that you've landed,

  • what happens next?

  • Your first goal will be to set up base.

  • And it can't just be anywhere.

  • Researchers believe the best place for a camp on Mars is near the planet's poles.

  • There you'll find massive ice deposits which are thought to contain large amounts of water.

  • We need water to survive, but it's heavy and takes a lot of room on a spacecraft.

  • To solve this problem, we could potentially turn this ice into water that we could drink, study, and use.

  • Scientists suspect that the ice deposits may also contain iron and sulfur, which

  • could be used for manufacturing in the future.

  • But that's in the long term.

  • For now, let's worry about your base being built.

  • Luckily you won't be building it,

  • as space companies intend to send a team of robots up there to assemble the base for you.

  • After that's done, you can finally move in.

  • The base will be roughly 12 m high (41 ft) and 5 m in diameter (16 ft).

  • That may sound pretty roomy, but you won't be alone.

  • Space companies are planning to send six people to Mars for the first expedition.

  • At least you'll have people to talk to while you're there.

  • Once you've landed you'll quickly notice how different Mars feels from Earth.

  • Mars has just one third the gravity that the Earth has.

  • NASA says that a person who weighs 45 kg (100 lbs) on Earth,

  • would only weigh about 17 kg (37 lbs) on Mars.

  • You'll be able to jump all around the planet.

  • But if that's all you expect to do, this trip won't be for you.

  • The first people on Mars will be unlike any astronauts we've seen before.

  • Apart from knowing everything about physics and spaceships,

  • they'll also have to be farmers, botanists, and excellent problem solvers.

  • One massive problem they'll all need to solve?

  • Food production.

  • Let's hope you like your vegetables because,

  • aside from astronaut food that's pretty much all you'll be eating.

  • A University in the Netherlands simulated crop growing on Mars,

  • and found out that potatoes, peas, carrots, and radishes could all grow on the planet.

  • You'll be able to use the soil from Mars and,

  • water will come from recycling urine and whatever other water products were brought onto the planet.

  • And speaking of human waste,

  • unfortunately, you'll have to use your poop to fertilize the crops you're growing.

  • Now that's recycling!

  • After about nine months of researching, farming, and exploring Mars,

  • you'll then begin your journey home.

  • This is arguably the hardest part of the trip.

  • You and your crewmates would hop into this Mars Ascent Vehicle or MAV for short.

  • Then you need to line it up, perfectly,

  • with the larger space ship, which is orbiting Mars.

  • The ascent up to your spaceship could take anywhere from half an hour, to several days.

  • It all depends on whether you can line up the MAV with the larger spaceship.

  • And if not done correctly, things could go very, very bad.

  • But if all goes according to plan, think of what you've just done!

  • You were the first person on Mars.

  • And after living there for months,

  • what you've learned will make it easier for future generations to live on the red planet.

  • Permanently!

  • But what would happen if, instead of going to Mars, you went to Venus?

  • Well, that sounds like a story for another, WHAT IF.
