“The obsession with Mars has been around for a very, very long time,” explains Olivier Hernandez, Rio Tinto Alcan's planetarium director. if Water signs They have been discovered on the planet, and there is no telling whether this water is suitable for fueling life.
“Mars would have looked like Earth a few billion years ago, but there were changes in the planet's climate, and in the planet's location as well, so the planet was no longer habitable at all.”
The planetarium is currently dedicating an immersive exhibit to Mars. During this exhibition, spectators are guided by artificial intelligence to learn more about daily life on the Red Planet. “Mars doesn't even have a magnetic field to protect it, nor an atmosphere. Humans find themselves facing these cosmic rays. It can make them infertile and have a big impact on the kidneys,” Mr. Hernandez explains.
And live somewhere else on another planet?
In the face of the challenges posed by Mars, other options such as Venus or exoplanets are being explored. “Venus is often called Earth's sister, but it has massive greenhouse effect, acid rain, and temperatures of up to 200 degrees Celsius. “It's not a good idea either,” fumed Olivier Hernandez.
Mercury has one side always facing the sun where it is very hot. “It's not a habitable planet either,” adds the planetarium director.
He states that exoplanets remain a “possibility”, but the reality of each of them poses many challenges to human life.
“There is no Plan B for the planet,” Mr. Hernandez concludes. “If our planet is no longer habitable, then it is Too bad for us!”
