They Said Mars Was Lifeless… Then NASA's Perseverance Sent This in 4K

Описание: The notion that Mars once hosted life has long fueled human imagination, particularly as the planet now appears as a desolate expanse. Scientific evidence suggests that the Red Planet experienced heightened geological activity and a significantly thicker atmosphere billions of years ago. This was especially evident during the Noachian period, approximately 4.1 to 3.7 billion years ago, when the atmospheric pressure is estimated to have been far higher than it is today — potentially sufficient to support stable liquid water on the surface. While this possibility is enticing, detecting past or present life on Mars remains a formidable challenge.

The search for extraterrestrial life often hinges on identifying biosignatures — chemical or physical traces that may indicate past or present life. However, focusing solely on traditional Earth-centric markers like oxygen (O₂) or methane (CH₄), while important, might be too limiting. Some astrobiologists hypothesize that potential Martian life could utilize unconventional biochemistries — perhaps incorporating elements like silicon (Si) or arsenic (As) as structural components, or relying on energy sources such as radiation or geothermal heat.

Beyond biological signatures, the question of Martian emptiness calls for exploration through a different perspective — that of consciousness. If intelligent life once inhabited Mars, could their existence have left behind traces beyond the physical realm? Imagine a civilization capable of manipulating energy at levels exceeding our current understanding, leaving subtle imprints on the fabric of spacetime itself.
