Mars is the fourth planet from the Sun and the second smallest planet in the Solar System. The reddish appearance of Mars’ surface is caused by iron oxide.
While the Mars is about half as big as the Earth, there are still many similarities: Mars has a rocky surface and polar ice caps, the days on Mars are only 40 minutes longer, the axial tilt gives it similar seasons to ours (although each lasts about twice as long).
Mars has a dramatic landscape, with towering volcanoes and a great canyon system. Of all the planets in the Solar System, it has the highest mountain, Olympus Mons, and the largest canyon, Valles Marineris.
There is strong evidence that the Martian atmosphere was once far denser than it is now, and that water once ran freely on its surface. There is also mounting evidence that much of this water remains locked away underground.
Mars has two small natural satellites, Phobos and Deimos, that orbit very close to the planet. These moons may be captured asteroids. It has been predicted that in about 50 million years, Phobos will either crash into Mars’ surface or break up into a ring structure around the planet.
Mars is the focus of intense study, with two rovers (exploration rover Opportunity and science laboratory Curiosity) operating on the surface, while three international missions orbit the planet: NASA’s Mars Odyssey and Mars Reconnaissance Orbiter and ESA’s Mars Express.
Mars can easily be seen from Earth with the naked eye, as can its reddish coloring. Its apparent magnitude is surpassed by the Sun, the Moon, Venus and Jupiter – but it can briefly match Jupiter’s brightness at certain points in its orbit.
The outer crust is rich in silicon, oxygen, iron, magnesium, aluminum, calcium, and potassium, all of which could be used in the development of future human outposts on Mars.
Silicate mantle was once very active, giving rise to many of the planet’s distinctive surface features, but which now appears to be dormant.
Like Earth, Mars has undergone differentiation, resulting in a dense core primarily comprising iron and nickel, but with around 17% sulfur, which renders the core partially liquid.

Oy. New video. Thanks
i call bs
Beautiful compilation. Thank you for sharing with us.
Thanx for sharing information about MARS on time to time by releasing videos
Millions of smashed martians on the tires of the rover so these rock hounds can look a more rocks.
Is the watermark there because you took the video yourself?
NASA releases some rock & sand videos periodically for YouTube viewers’ entertainment.
Very nice video that I love ! Thank you for sharing . Can we stay on the Mars planet too ? Happy week to you !
Q presioso planeta es Marte , es el hermano menor gemelo d nuestro planeta Tierra , algo fuerte ha sucedido en este planetta q esta desertico y desolado , la caida d un asteroide inmenso colosal ha barrido con tda vida extraterrestre
I know this place : great sand desert in Australia
Beautiful vistas aren't they? I understand the urge to explore, excitement and romance the adventure ahead holds for manned exploration of Mars . Right now it's the orbiters, landers and rovers who are our eyes,ears ,feet and hands . Eventually humans will be there to pick up where our sturdy machines left off. But hopefully only for exploration and scientific research and nothing more. We do not need to colonize Mars. It was not made for us period. If we do I know we will be the so called term " Ugly American" only scratch off American and insert Human instead. Exploration is in our DNA,, but so is destruction. Soaring above the clouds of Venus and Jupiter,, examining the curious and dynamic moons of Jupiter and Saturn,,the asteroids and comets of the Oort cloud so many places to see . But knowing only that we must always return to Earth . Mars belongs to Mars . Earth belongs to Earth. And we humans are currently her caretakers. And look at what we have done to her. Beautiful vistas aren't they?
Nice job, thanks
Boring, dead Mars.
Hey guys, can I ask something. Why do we believe nasa without question? I mean is it smart to give any one you unquestioning loyalty?
I think a wise people would not do so. Especially with a government agency to boot.
I just have seen a lot of nasa faking and lying lately.
Yeah you have to dig a little. But giving away moon rocks that turned out to be fake.
And have you seen that black and white video of the guy floating outside a spacecraft?
You do not need anyone to tell you that is fake.
Which make me wonder. If they were lying to us way back before they handed the reins over to the nazi scientist, (Von Braun?) they when did they quit lying to us?
Just thinking. You know question everything.
I welcome anyone’s feed back. I will say that if you don’t read what I wrote then you feed back is pointless. And it is likely to just be ridicule and/or mockery.
Which will just show you have no good counter points and are triggered by people asking questions.
Thanks sincerely Luke C
This is what earth is going to look like after humans get done with it.
..,,,,,,these rocks have been here for over 1 MILLION years,,this impact happened over 1 MILLION years ago,…,,,,,,our tracks on mars,,,will be there for MILLIONS of years to come,… ( minds eye),,,
wow
Fun fact… Mars does NOT have a blue sky!!!
