At least that is the theory proposed by a scientist who has discovered a reason as to how the red planet got its rosy colour.
According to Dr John Brandednberg, about 180 million years ago, a planet-shattering yet naturally occurring nuclear reaction may have wiped out everything on Mars, sending a shockwave that turned the planet into dry sand.

'A nuclear explosion could have sent debris all around the planet.
'Maps of gamma rays on Mars show a big red spot that seems like a radiating debris pattern ... on the opposite side of the planet there is another red spot.'
Dr Brandenburg, who is a senior propulsion scientist at Orbital Technologies Corp, said the natural explosion - the equivalent of one million one-megaton hydrogen bombs - occurred in the northern Mare Acidalium region of Mars where there is a heavy concentration of radioactivity.
This explosion also filled the Martian atmosphere with radio-isotopes, which are seen in recent gamma ray spectrometry data taken by NASA, he said.
The radioactivity also explains why the planet looks red.

Dr David Beaty, Mars programme science manager at NASA's Jet Propulsion Laboratory, told FoxNews.com that he finds the idea intriguing and fascinating.
But he said to prove the science, the agency would need to plan a mission to explore Mare Acidalium on Mars.



Here is a piece of a channelling I've read.
"As the Mars civilization continued to grow, unrest between the various factions grew..............A form of dirty atomic bombs were developed, using heavy metals (Uranium, Plutonium, etc.) and a war broke out using these weapons.........the Martians blew holes in their atmosphere and severely disrupted the ecological balance to the point of rendering most surface life forms extinct. Some survivors of the atomic bomb blasts made their way underground and........Your scientists will discover some radioactivity on Mars that cannot be explained solely by natural rock formations - this is the residue of the atomic explosions, since some of the elements used have a half-life of millions of years................This is the end of Part 5. We are the Founders".
