Known as the Red Planet, Mars is a small and cool planet relative to Earth. Most of its volcanic and tectonic activity occurred over three billion years ago. Because of that, planetary scientists have considered Mars an “essentially dead” planet, with very little geologic activity.To date, no proof of past or present life has been found on Mars. Cumulative evidence suggests that during the ancient Noachian time period, the surface environment of Mars had liquid water and may have been habitable for microorganisms, but habitable conditions do not necessarily indicate life.Article II of the Outer Space Treaty states, "Outer space, including the moon and other celestial bodies, is not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means." In short, nobody can claim ownership of Mars or land on Mars, or do so with any other …
Does Mars have a dead core : Like Earth, Mars appears to have a molten iron core, or at least a molten outer core. However, there does not appear to be convection in the mantle. Presently Mars shows little geological activity. The elemental composition of Mars is different from Earth's in several significant ways.
How was Mars killed
Without that protection, Mars lost its atmosphere. Without that atmospheric pressure, the water on its surface boiled and evaporated into gas, where it too got caught up in the solar wind and blown out of the solar system. That water has now joined its brethren in the interstellar wastes, never to be seen again.
Is Mars still alive : While Mars is not as geologically active as Earth, it is not completely dead. Evidence suggests that Mars had volcanic activity in the past, and there are signs of ancient riverbeds and lakes, indicating a history of liquid water.
Mars might not be somewhere we could live. We are not sure how effective Mars's atmosphere would be as a radiation shield (how will astronauts hide from radiation on Mars) And we must remember that the explorers will have to spend a long time on the planet. There can be no quick there-and-back dash, as with the Moon. Ancient Mars had seasonal weather similar to Earth's, with alternating wet and dry seasons, according to mud patterns discovered by NASA's Curiosity rover. These seasonal cycles may have helped form some of the more complex building blocks for life, such as RNA and basic proteins.

There can be no quick there-and-back dash, as with the Moon.When Forrest Sr. died in 1999, his children — Jacqueline, John, and Forrest Mars Jr. — inherited a stake in the company. Currently, 84-year-old Jacqueline and 88-year-old John co-own — but don't actively manage — Mars Inc. They have the biggest share of the family fortune.Its small size—about half the diameter of Earth and less than one-ninth the mass—simply never produced the gravitational muscle to allow the planet to hold onto either its air or its water. With or without a magnetic field, Mars was destined to die. Now, Venus is a mostly dead planet with a toxic atmosphere 90 times thicker than ours and surface temperatures that reach 864 degrees, hot enough to melt lead. It's often called Earth's twin because the planets are similar in size. But the modern comparisons stop there.
What destroyed Mars : Mars lost its global magnetic field about 4 billion years ago, leading to the stripping of much of its atmosphere by the solar wind.
Why did Mars go extinct : In a surprising twist, the study revealed that while ancient Martian life may have initially prospered, its chemical feedback to the atmosphere would have kicked off a global cooling of the planet, ultimately rendering its surface uninhabitable and driving life deeper and deeper underground, and possibly to extinction.
Is there oxygen in Mars
Mars' atmosphere is almost entirely made up of carbon dioxide (CO₂) – 96% of the planet's air contains CO₂. Oxygen is only at 0.13%, compared with 21% in Earth's atmosphere. Kepler-452b (sometimes quoted to be an Earth 2.0 or Earth's Cousin based on its characteristics; also known by its Kepler Object of Interest designation KOI-7016.01) is a super-Earth exoplanet orbiting within the inner edge of the habitable zone of the sun-like star Kepler-452 and is the only planet in the system …Mars may once have been a blue and water-covered world long before Earth even finished forming. That's the tantalizing finding that researchers from Arizona State University and Stanford University announced on October 18, 2022.
Is there oxygen on Mars : Mars atmosphere composition
According to ESA, Mars' atmosphere is composed of 95.32% carbon dioxide, 2.7% nitrogen, 1.6% argon and 0.13% oxygen. The atmospheric pressure at the surface is 6.35 mbar which is over 100 times less Earth's. Humans therefore cannot breathe Martian air.
