Applying the film, If the core of the planet cools, the planet is dying, because it disappears EM field that protects the planet.
On Mars there is a huge volcano(According to scientists, the largest in the solar system.) which was derived its strength, possibly(?) directly from the core.
If the volcano erupted long enough, it could cool the core, strong enough to cause the death of Mars, turning off it EM field?
How this volcano has arisen?
 
Astronomy news on Phys.org
As the planet's core cools it loses the magnetic field that protects the surface from some of the radiation from the sun.
It's not necessarily true that there can't be life on planet with no magnetic field - it's just that if the Earth's field went away we would be in trouble,

A single volcano doesn't have much effect on cooling a planet.
Olympus mons is just large compared to mountains on Earth because Mars' lower grav ity means you can form bigger mountains before they sink under their own weight
 
"Applying the film, If the core of the planet cools, the planet is dying, because it disappears EM field that protects the planet."

You have to have something alive on the planet before it can die. Hot OR cool, Mars is still there, and 'alive and well' as it will ever be.
