The fourth planet from the sun and the outermost of the terrestrial planets, Mars has long been a popular spot for missions and imagination. Phil walks you through the planet’s topography, core, and features. We’ll take a look back to Mars’s past and makes predictions for its future, including the possibilities for human life.

But can you see the Sun with the naked eye from Mars? Or is it still too bright?
TIP > Melt Mars's Ice and make a colony underground = LifeInMars
I just learned the past info and it is colder. XP
I want to be Mark Watney.
Wait, they need to dig 10-15 meters in the riverbed to find fossils?
Earh has a megnatic field that protects us against the solar wind and also has a greenhouse effect, would it be possible to create a megnatic field by manipulating nature on Mars? I just started getting into astronomy and it's like learning a long forgotten language to me.
Don't drink water on Mars… At least without a filter.
very interesting!
WHO ELSE SICK OF THE SNOOP DOGG BK AD ??????
The earth is flat
I still love the idea that Mars is the only planet we know off that is inhabited solely by robots :)
Astronomers called it Saturn cause it had a nice ring to it! :D
Wait, if we use the lava chambers as a base, and we get into them using the collapsed skylights, then couldn't they collapse again?
damn you rule Mr plait!
ok ok so WHAT IF there was life on Mars when the atmosphere was thicker and there were large bodies of water, but the beings of the planet did what we are doing and released huge amounts of greenhouse gases into the atmosphere over a period of time, and they slowly wore down their atmosphere until it was extremely thin and all of the water evaporated.
KERBALS !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Aaaahh you showed us an animation of SpaceX's Falcon Heavy <3
I am supremely satisfied by that. It's going to launch and land its boosters in April! So excited
Could you imagine in 1000 years people living on both mars and earth like it's the norm. Like hey mom I'm thinking about moving to mars you wanna come?
any aries (and maybe scorpios) here?
if we were to colonise Mars, would we have to make new timezones for mars? How many days or even weeks is Mars ahead or behind us in time…..same question kinda goes to the Moon as well
I love that little visual shout out to SpaceX. There's no other group more determined to get people to Mars
there is liquid water on Mars !!!!!!!!!
i love this channel!!!!!!
You guys should update this video to take account of NASA's new finds. Seasonal Liquid Water!
