A spectacular color video shows us Mars with very high definition thanks to the images of the NASA MRO probe: enjoy
Spectacular video of Mars in 8k: the red planet in colour! Mars has its peculiarities in fact the sunsets there are blue and the days are red. But its surface is not exactly an arid desert. Using images from HiRISE, the probe’s camera Mars Reconnaissance Orbiter (MRO) from NASA, let’s see what the planet’s surface looks like from very close.
In its small way, Astronomy Passion helps you understand how the universe works. And the universe works best if the people in it are well informed. If they have read nonsense, lies, poisons, then it ends as it ends. Right now it’s not going very well. That’s why it’s important that someone explains things well. Passion Astronomy does its best.

Some info on the Red Planet
With an average radius of 3,390 kilometers, Mars is about half the size of Earth. The Red Planet is on average 228 million kilometers from the Sun, equivalent to 1.5 astronomical units (oneastronomical unit “AU” is the Earth – Sun distance ie 150 million kilometers). Mars completes one rotation every 24.6 hours and is very similar to a day on Earth (23.9 hours). Martian days are called sol and a year on Mars lasts 669.6 sols equivalent to 687 Earth days. The axis of rotation is inclined 25 degrees with respect to the plane of its orbit around the Sun. This is another similarity to the Terra, which has an axial tilt of 23.4 degrees. Mars has distinct seasons, but they last longer than Earth’s seasons since it takes longer to orbit the Sun (it’s further away). Also, the length of the seasons varies due to the elliptical, egg-shaped orbit. A large system of canyons, called “Valles Marineris“, extends for 4,800 kilometers: at its widest point it measures 320 kilometers and 7 kilometers at its deepest point. It’s about 10 times bigger than the Grand Canyon of the Earth. The Red Planet is home to the largest volcano in the solar system, Olympus Mons: it is 25 kilometers high and has a base with a diameter of 600 kilometers. Our planetary neighbor is a world yet to be discovered!
