I did not know : https://sciencepost.fr/vladimir-komarov-soyouz/

This is the story of a cosmonaut named Vladimir Komarov who agreed to fly aboard an already doomed ship to protect his friend.

This is the story of a cosmonaut named Vladimir Komarov who agreed to fly on an already doomed ship to protect his friend Yuri Gagarin. He was the first man to die on a space mission.

Yuri Gagarin is known to have been the first human to go into space, in 1961. Although he never flew again, his expertise was called upon a few years later, in 1967, for a flight that was to integrate his friend Vladimir Komarov, whom he had to replace if he encountered a problem.

At that time, the Soviet Union was about to celebrate its 50th anniversary. To mark the occasion, authorities decided to release two spacecraft into orbit. Piloted by Vladimir Komarov, Soyuz 1 was to be launched first, before being joined by Soyuz 2, with three other cosmonauts on board. The two capsules were then to meet, Komarov was to make a spacewalk and integrate Soyuz 2, while two of the cosmonauts on board Soyuz 2 were to integrate Soyuz 1. All these beautiful people then had to return to Earth.

Following the shutdown of the Soyuz launchers, in cooperation.

The European Space Agency suspends the ExoMars mission.
The ESA said it was abandoning the ExoMars mission, which aimed to send a rover to the red planet.
The mission relied in particular on a Russian launcher and lander.

It would be funny if once the Americans and the Germans left, the Russians took over the ISS : Mrgreen: Counter-penalty!

And there the media should listen well to what the Russians have to say... : Mrgreen: : Twisted:

No
Mars, Earth, and Venus were arguably accreted from the same base materials, which means they must have experienced great similarities early in their history. But while Earth and Venus retained most of their thick atmosphere, Mars, due to its small size and low gravity, was unable to retain its atmosphere over time.
It is indeed this “escape theory” which explains the current thinness of the atmosphere of Mars. This escape occurs very high in the atmosphere, above 200 kilometers, where the molecules have already dissociated into atoms and where the lighter ones, such as hydrogen, can tear themselves away from the weak gravity of Mars. Exposed to the energetic particles of the solar wind, this "exosphere" of Mars is also its "Achilles heel", because over time it has allowed the equivalent of hundreds of current atmospheres to be lost in space.

Clouds of ice but not until creating a greenhouse effect, except a few billion years ago...

You have to read the article to the end which explains why:
the initial quantity of water on Mars must have been at least 6 times greater than now, or the equivalent of a liquid layer of a hundred meters covering the planet.

Supermoon!

There it is Art (finally NFT business), an assembly, but I think that with suitable equipment, a mega zoom and a motorized tracker tripod we could make a real one! 8)



Obamot? You are a photographer I believe! Go to work !
