NASA's Newly Released Images Of MARS #53 (2024)

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.

  2. Always a wonderful gallery of images from the Red Planet, full of amazing vistas and detail. I always in awe of the SCALE in the scenes, just incredibly massive valleys and the mounts are HUGE!!!
    Thank you for uploading this!

  4. È evidente, da quello che si vede, le sedimentazioni,i letti di antichi fiumi, il livello dell'acqua, che Marte in un remoto passato aveva in abbondanza acqua liquida.
    Evidentemente si trovava in un'altra orbita più vicina al Sole così che l'acqua potesse rimanere liquida.
    La migrazione orbitale lo ha portato ha una distanza maggiore da Sole, insieme ad altri fenomeni che hanno contribuito a fare sublimare la maggioranza dell'acqua, facendo congelare in alcuni posti, quella che è rimasta. Così che Marte sia il deserto desolato privo di vita che si vede.
