If only there were some sign of a collision on Mars.

A study published in the journal Earth and Planetary Science Letters posits that Mars formed in what today is the Asteroid Belt, roughly one and a half times as far from the Sun as its current position, before migrating to its present location.
The assumption has generally been that Mars formed near Earth from the same building blocks, but that conjecture raises a big question: why are the two planets so different in composition? Mars contains different, lighter, silicates than Earth, more akin to those found in meteorites. In an attempt to explain why the elements and isotopes on Mars differ widely from those on Earth, researchers from Japan, the United States and the United Kingdom ran simulations to gain insights into the Red Planet’s movement within the Solar System.
Even though the study’s simulations suggested that the most probable explanation is that Mars formed near Earth, that model doesn’t account for the compositional differences between the two planets. Thus, researchers paid particular attention to simulations consistent with the so-called Grand Tack model, which suggests that Jupiter played a major role in the formation and final orbital architecture of the inner planets. The theory holds that a newly-established Jupiter plowed a large concentration of mass towards the Sun, which contributed to the formation of Earth and Venus, while simultaneously pushing material away from Mars, accounting for the planet’s small mass (roughly 11 percent that of Earth) and the difference between the two planets’ compositions.
In Grand Tack simulations, the researchers gleaned additional insight into Mars’ formation. A small percentage of the simulations suggested that Mars formed much farther from the Sun than it is now and that Jupiter’s gravitational pull pushed Mars into its current position.

The composition is not nearly as great as Earth so why try to live there? MEGA - Make Earth Great Again.

True - Mars lived across town, next to the old mill.
I think Mars is what is left of the collision between a planet and a large rock where the asteroid belt currently is.
I never liked Mars, to be honest.
Thanks for posting this article.
I hope you don’t mind me saying that it is full of gibberish.
Those Martians were always over borrowing stuff.
A cup of sugar.
A screwdriver.
Some asteroids.
I agree. There is about 10% good points and the rest unsubstantiated speculation. There is a great deal of speculation on planet orbits being influenced by the major planets. I have a hard time seeing planet influence overpowering the gravity of the sun.
Mars and Earth are not neighbors now, they are 30+ million miles apart!!
If only there were some sign of a collision on Mars.
From the grave, Dr. Velikovsky says “Hear, hear”.....
If no tectonic shifting, then one hell of an impact.
Would be interesting to compare the composition of a few random asteroids many degrees apart along their plane of orbit.

Here’s a short video which presents a novel, but well founded theory about the formation of Valles Marineris, Olympus Mons, and other Martian features:

Mars did not form in the asteroid belt. Mars formed the asteroid belt. Ancient Martians saw the fifth planet as a threat. After grokking the threat, they destroyed the planet. The asteroid belt is what remains.
Dr. Velikovsky - have not heard hat name in many years. His books, right or wrong, were mind opening. I especially liked ‘Ages in Chaos.’ I still have most of his books in my collection.
