What Can The Most Powerful Satellites Really Do?


Hey there, welcome to Life Noggin. Ohhh a space artifact! I wonder what it is! This video was made possible thanks to WIX! If you’re looking to create a website, head
on over to wix.com/go/lifenoggin In the big, scary abyss of space, it can get
pretty lonely! The planet Earth knows that all too well. Venus, which is the closest other planet to
Earth, is still millions and millions of kilometers away from the human homeworld, even when they’re
closer together in their orbits. That’s why it’s good to have some closer
friends around you, you know, to keep you company. Thankfully, the Earth has satellites — and
quite a lot of them. When you think of a satellite, you’re probably
mainly thinking of human-made technology, but NASA actually defines one as any moon,
planet, or machine that orbits a star or another planet. Not only does that mean that the Moon is a
satellite of Earth, but also that the Earth is a satellite of the Sun. These are both examples of natural satellites. Of course, we also have artificial satellites
that were put up there by you humans. These officially became a thing around the
middle of the 20th century with the Soviet Union’s successful launch of Sputnik I.
Fast-forward to now and there are thousands of artificial satellites up there orbiting
Earth. And the things have gotten pretty darn impressive! For example, they can take pictures of other
planets and celestial bodies, or turn their eyes back on Earth to help predict weather
or track storms and wildfires. They can even measure atmospheric gases, like
ozone and carbon dioxide. Oh yeah! And satellites can also play a role in allowing
you to make phone calls and letting you watch your favorite TV shows. But they can also take photos of other planets! Guys? Huh… They are stuck watching their shows. Not to mention how impressive the International
Space Station is, which comes in at about the size of a football field and weighs about
as much as a few hundred cars. Ok, now we’ve enticed the space strongmen. Put the thing down, ok? You’ll knock it out of orbit! But it’s not just big space stations that
are great feats of humanity. Going smaller is equally impressive. Just like you’ve seen smaller and smaller
technology down on Earth, the miniaturization of computers and hardware has made its way
to satellites. With NASA’s CubeSat Launch Initiative, a
bunch of super small satellites are being put up into orbit. Called CubeSats, these nanosatellites are
roughly 10 by 10 by 10 centimeter cubes that tend to weight a little over a kilogram. They allow you to test out new technologies
— like the RainCube, a miniaturized precipitation-studying radar instrument — in the real-life harsh
environment of space before being used in more advanced missions. And if you want to see the view from space
yourself, NASA’s High Definition Earth Viewing, or HDEV, experiment became operational back
in 2014. This initiative put commercially available
HD cameras on the exterior of the ISS so that they could stream live footage of Earth that
you can view right from your computer. Imagine going back in time and telling a group
of people from the 1940’s that all of this is going to be possible! You get to experience all of this right now! Oh man, satellites sure are pretty cool! Now if we can just get them to shoot down
space lasers for when those evil underground bugs attack. If you wanna capture stunning photos of space,
you need to send up a powerful satellite If you wanna make about Satellites, you need
a powerful builder. Our friends over at Wix, who sponsored this
video, have the easiest and most intuitive way for anyone to build and run a stunning
website. It’s perfect for anything LifeNoggin.com
to my secret photography dog blog. You can simply pick from 100s of beautiful
intuitive templates and customize anything you want! You can start creating your own website for
free! and if you want your own domain and more awesome features you can upgrade to one
of their premium plans! Plus you can add your own fonts, image galleries,
interactive elements and more! Wix does all the heavy lifting so you can
have the freedom to make you’re site truly you. So do you have any space related space questions
that you want to ask? Let me know in the comment section below and
we might turn your question into a future video! As always my name is Blocko! This has been Life Noggin! Don’t forget to keep on thinking.
