Space! And discovering the remaining 80% of the uncharted Earth?

You know, going to space is one thing. And as the movie gravity will tell you, without any spoilers too : coming home is equally as a goal for those up there.

And apparently, as we see things burn up in the sky at night, with some people still insist on "wishing upon a "shooting star"", it goes to show that falling down towards earth, and going through all the many lines scientist have named around the different latitudes in the atmosphere, is not some hot air/serious stuff!

Think coming down is as simple as just falling down? Think again.

So it goes without saying, it will be an awesome SciShow Space ( yeap, that's scishow for all them space lovers out there) video to cover.

Now facing the opposite way, lets figure out what's still such a mystery for Earthlings : what's underneath the oceans?  Because apparently, even though it covers about 80% of our earth, the knowledge of even how it looks like is abysmal.

Could you actually believe we only have charted the 20%, which is land?  Amazing huh. So it's even more amazing now that we're able to get a better map of what actually makes up most of our earth's surface.

Oh and don't worry : there's also spacewalks included.
