The First Human to Walk on Mars is Alive Today!

– Could the first human
to set foot on Mars be standing right next to you? (energetic techno riff) When I look at the Moon and think “45 years ago, humans set
foot on that surface,” I’m filled with awe. And NASA has continued the
mind-boggling full steam by recently suggesting that
the first people to set foot on Mars are already walking around today. So, is it possible that humans will visit the red planet
within a generation? You know, we’ve been talking about going to Mars for decades. Back in 1989, NASA had a
proposed plan that involved a spectacular thousand ton cargo ship built in space, among other things. They didn’t put a price
tag with the project but other people estimated
the cost would be at around 450 billion dollars. (record scratches) What’s the big deal? I mean we’ve been to the Moon why is Mars so much more difficult? For one thing, Mars is much father away. The Moon orbits Earth,
but Mars orbits the Sun. Now sometimes, Earth and Mars pretty close together. And other times they’re on opposite sides
of the Sun from each other. Which is really far out there. If you launch under ideal conditions it could take between six to
eight months to get there. That’s how long it took
the Curiosity rover. So if we sent human astronauts it would take them six to eight
months to get to Mars then they’d have to wait
on Mars until the orbits came back ’round again
for ideal conditions then another six to eight
months to get back home. That’s a long time. It’s also a much more
dangerous trip than going into low Earth orbit, or
even going to the Moon partly because we would be
outside the magnetosphere which protects us from
stuff like cosmic rays. Once you leave that protective
boundary, your spacecraft has to have the proper
shielding to keep you safe. So, what is NASA’s proposed approach? It’s pretty methodical. It actually starts with
capturing asteroids or at least part of one, and
putting it in lunar orbit then sending a series of manned
missions to that asteroid to test out the different
processes and technologies that’ll help us get to
Mars and back again safely. Those improvements could
include everything from brand new space suits to a
solar-powered ion drive vehicle that can dock with other
spacecraft in space. Meanwhile, other people,
like the Mars One project have a different approach. Their, let’s say ambitious plan is to get
human beings on Mars by 2025. Now how do they expect to do that? Well, it’s a one-way ticket. You would go to Mars and you’d pretty much stay there for the rest of your life. You’d become a colonist,
you know, a citizen of Mars. (spooky music plays) Martians. Personally, I lean a little more toward NASA’s methodical approach. But either way, striving to
get to Mars is a great goal. We’re going to learn
so much in new science and develop new technologies
that could benefit us in was we can’t even anticipate. And you know, human
curiosity is one of those resources we’re never gonna run out of. I’ve got a question for
all of you this week. What would it take to convince you to go on a mission to Mars? I wanna know in the comments below. And if you enjoyed this video make sure you hit that “Like” button and join our spacefaring crew
