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.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.The surface of Mars is barren and inhospitable, but perhaps it wasn't always that way. Billions of years ago, when life emerged on Earth, the climate of Mars could have been Earth-like as well, with a thicker atmosphere than today and oceans of liquid water.
Is Mars bigger than Earth : Size and Distance
With a radius of 2,106 miles (3,390 kilometers), Mars is about half the size of Earth. If Earth were the size of a nickel, Mars would be about as big as a raspberry. From an average distance of 142 million miles (228 million kilometers), Mars is 1.5 astronomical units away from the Sun.
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.
When was Mars dead : On Earth, life arose very early on and has survived ever since in an unbroken chain, but Venus died relatively quickly, and Mars died after about 1.5 billion years, both for very different reasons.

That water has now joined its brethren in the interstellar wastes, never to be seen again. Currently, the surface of Mars is bathed with ionizing radiation, and Martian soil is rich in perchlorates toxic to microorganisms. Therefore, the consensus is that if life exists—or existed—on Mars, it could be found or is best preserved in the subsurface, away from present-day harsh surface processes.
Did Mars have life
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.While Mars' day and general composition are similar to Earth, the planet is hostile to life. Mars has an unbreathable atmosphere, thin enough that its temperature on average fluctuates between −70 and 0 °C (−94 and 32 °F), yet thick enough to cause planet-wide dust storms.However, the surface is not hospitable to humans or most known life forms due to the radiation, greatly reduced air pressure, and an atmosphere with only 0.16% oxygen. Mars may look hot, but don't let its color fool you — Mars is actually pretty cold! In orbit, Mars is about 50 million miles farther away from the Sun than Earth. That means it gets a lot less light and heat to keep it warm. Mars also has a hard time holding onto the heat it does get.
Why is Mars a dying planet : This was Mars's flaw. Born too small, within a billion years its core cooled and solidified, its magnetic field becoming feeble. Without that protection, Mars lost its atmosphere.
Can Mars core be restarted : The first — restarting the core — is little more than a fantastic dream. Though Mars has a molten iron core, the authors of the paper conclude that warming it enough to restart magnetism would take a huge amount of heat.

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.
