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.

Oh a new video. Thanks. Happy new year ❤🎉
After Musk commung out, I cannot listen anymore to sheetS.
Great Video as always, Love the blue sleeping wolf dunes at 18.00…. Happy 2025 to you !
What's the blue image around 17.25?
The only thing that would make this footage better was if Elons starship touched down in the background.
No faux red sky. Great!
I'd be tempted to take my helmet off and find out what Mars smells like.
Awesome video that I like ! Thank you for sharing . Happy new year to you with all of your best wishes !
I'm sorry all that money we've spent and it's dirt it's nothing but really bad dirt that nothing grows and it's dirt no air and dirt what a waste of money
And don't get me wrong I'm not anti space exploration I mean Hubel and webb were awesome but all this money on Mars there's nothing going on there why do we keep spending money there
I mean come on this is worse than Arizona in the summer time but it's about what minus 100° their yeah buddy I want to go there
~£€§¥£❤¥£€😮~AVEAve~
I remember thinking I'd jump at a chance to go to Mars, but then I read "The Martian".
Countless billions spent on more pictures of rocks rubble and sand.
Soo Cool !!!
If I could live my life over again, I would have studied astrophysics, celestial mechanics & dynamical astronomy…
No matter what the naysayers have to say, you will never stop the wonderment and curiosity of the scientific mind…
Thus, because of this mindset, this has enabled us to communicate worldwide in nanoseconds and survive as a species…
… I never seem to know when these videos show the colors as they would appear to the human eye in Mars’s dimly lit daytime. Sometimes we see color-corrected, etc. images but we’re not told if this is the case here or not.
Thanks for the forecast! A bit off-topic, but I wanted to ask: My OKX wallet holds some USDT, and I have the seed phrase. (alarm fetch churn bridge exercise tape speak race clerk couch crater letter). Could you explain how to move them to Binance?
