MARS planet long ago was wet.🤽♀️🤽♂️♀️

That is a known fact so tell us something we don't know.

I haven't read any scientific articles but I think wet Mars' water was blown off into space over millions of years when its magnetosphere started collapsing.
Solar wind forced the water into space, which became water ice.
The ice was then swept outward to Jupiter/Saturn and as time ticked by, gathered on moons and in the ring systems.
Its a known fact the Jovian and Saturnian systems have large amounts of water ice surrounding them.
Since our star is slowly rising in temperature as it ages, there may come a time in the far distant future when the Jovian and Saturnian water ice rises in temperature enough to cause water droplets to form on the different moons.
Perhaps 3 or 4 billion years from now. The Earth will be a burnt cinder and Mars may have Earth's water from the same process which caused Mars to lose its water in the past.
Mars could turn wet again but the planet has no protection from solar/cosmic radiation because its magnetosphere no longer exists. Basically, a planet of water but only simple life forms at the bottom of very deep oceans..
Eventually, when the Sun reaches red giant stage, some of Jupiter's moons may be warm enough for liquid water and protected by Jupiter's magnetosphere, eventually develop life.
Additionally, due to the changes in gravitational waves from a larger less dense star, many long duration comets may impact the Jovian moons populating them with long dormant life-giving compounds and even more water ice.
Chances are, Europa could be similar to Earth, eventually.
Its large enough to have a similar gravity which would allow for the processes to occur for atmosphere and resultant weather to form. A water based atmosphere might also increase the pressure enought to allow for complex life forms to develop.
Given enough time, water and heat, it could develop an Earth-like environment.\
But, I'm talking about over a billion or more years.
Its a fact the Sun is growing hotter.
Its a fact as the Sun grows hotter the goldilocks zone moves outward.
Its a fact the Sun will become a red giant.
Its a fact the Earth will be too hot to allow water.
Its a fact Mars will get hotter and the frozen water ice will melt.
Its a fact the gravitational effects of the Sun will change over time.
Its a fact the solar system will have different periods of stability with periods of instability as the properties of our star changes.
All planetary systems will experience significant bombardment and material deposits.
Our Sun has a 10-15 billion year life span. It is currently in the early stages of its main sequence which gives its system a long duration stability.
Its getting hotter as it ages but currently slowly.
The red giant stage will have far greater periods of stability.
The red giant stage will slowly cool.
As it cools, the solar system will freeze again until evetually the entire system is a frozen, dead remnant circling a small white dwarf star. Eventually, even that will grow cold and dead.
The heliosphere will collapse and cosmic radiation and debris will invade our system until a nearby star forms or goes nova and sets the frozen husks of matter into new trajectories. What remains of Earth and other planets might, one day, be be captured by a nearby star and the life process restarted arond a different star. Or...The planetary husks could collide with other mass and be pulverized into dust.
In 8 billion years from now, the Universe will be over 20 billion years old (by some estimates). The Sun is a second generation star at least. This is fact because elements which form from stars already exist in our star system.
For those elements to exist here, other stars had to form them, explode the material into space and then gather that material by gravity to form our star system.
The fact Mars had/has water is insignificant.
