First look at Mars's interior reveals a different picture than Earth It has a big, liquid core. By Kellen Beck on July 24, 2021 Online
Why should it be liquid, since it's so cold? Don't believe a word of it.
New in cosmology and fundamental physics

How close? Epic claimed to take the very best photo of earth from more than a 1/2 million miles away.
Or was it a million miles?
I really can't keep up with all the changes.......perhaps that is the purpose!?

The surface temperature is not important. The flow of heat is very low.
Remember the surface of Earth is cool (some frozen), but it is all red hot or molten except the crust.

Elroch - Your buddies at NASA claim to remotely control robots on Mars. Both on the surface and in the air.
Where is the evidence?

Because of internal movement and therefore friction. But Mars is a lighter planet than Earth so isn't likely to have a larger molten core.

Actually the internal temperature of the Earth is due to radioactive decay. Relative motion is way too small to last.

The evidence is the observations.
Things go wrong too. Again the observations (or the failure to receive them) provides information on that.
The primary contributors to heat in the core are the decay of radioactive elements, leftover heat from planetary formation, and heat released as the liquid outer core solidifies near its boundary with the inner core.27 Sept 2022>>>>>
Oh I see. Radioactive decay. So perhaps Mars had a higher concentration of heavy elements for some reason.

Thanks, I'd already found it. I remember now being told that when I was a very small person. Completely forgotten & I didn't realise it would be so significant.

Elroch - If NASA says "we have a problem" then everyone better get down upon their knees like they did with Apollo 13.
NASA claims to have robots on Mars. Some roaming around on the surface and at least one hoovering above the surface like a helicopter.
All equipped with cameras.
And all you can come up with is "tech problems"?

The sky is falling, ..........................trapped like rats.....or guinea pigs, ..............................................................................................life SUCKS!
I read somewhere once that if you were outside during a sudden polar shift, it would appear as though the sky was falling...

Life is too short to keep star wars secrets.
According to 70's tabloids, the deleted dialogue between Han Solo & Princess Leia Organa prior to Hans being frozen stiff in Carbonite until Return of the Jedi, was "I'll be on Pluto...dreaming of Uranus"

This whole NASA thing is just so annoying. It makes of the rest of the World a meaningless detail.
France has, since like two decades ago, the World's leadership for lauching commercial satellites into space, from their Kuru Base (French Guinea, South America), and, again, it's the Russians alone who ensure the transportations of astronauts to and from the ISS station (shuttles launched from Baikonour).
The NASA has like zero influence over the World outside USA, which is a rather small part of the whole World, especially in terms of population.
I mean, give us a break with your American stuff that, in your mind, would be ruling the World. And quit believing, the rest of the World is a detail and produces only little gadgets every now and then, while USA alone would bring technology to the World. I could ramble for pages about it, don't make me do that, thank you.
NASA annoys me, ever since someone somewhere tried to use a NASA article in support of the Big Bang Theory, arguing that if NASA supported it, it must be correct. The article was of the standard of a badly written Wiki article, dumbed down so peanuts could read it and totally non-scientific. Yet the silly person believed it because it was Nasa. So I looked at some other stuff by them and it was all pretty much junior school level. As a teaching organisation, they are inept and useless.
That doesn't mean anything with regard to going to the Moon etc.

NASA's popularity is waning. There main function has always been propaganda. That is why they are hitting the schools kindergarten level. Show the kids a few magic tricks inside the ISS and they will be hooked!
I think NASA has stated they will retire the ISS in 2030?!
Interested no matter how one looks at it.
Are they going to have a moon base by then
If you want to take a picture of Earth, it's best to be closer. From Mars, the Earth is 210 times smaller than the Moon is from Earth.
The (quite) recent pics of Pluto were magnificent.
