Is Ceres as easy as going to Mars?
Robotically, orbited both. But we going to talk about crewed missions which hasn’t been done.
It seems to me we need artificial gravity to do either.
So assuming we can do artificial gravity, is Ceres as easy as Mars?
Ceres takes longer.
But with artificial gravity, does it matter much?
It seems the light speed difference could be more important problem between Ceres and Mars.
I think have artificial gravity station at Venus orbit, say at L-1 could useful for abort/alternative paths to Mars and from Mars to Earth.
And starting at Venus L-1, would be faster to Ceres- and faster return to Venus and you can aerobrake/orbital capture with Venus atmosphere.
So, if and when we do Mars crew exploration and have developed artificial gravity so that human can live in space. And put fuel depot at Venus orbit. Then crew exploration of Ceres, could be as easy as going to Mars {or a lot easier}.
If the Moon doesn’t have mineable water, and Mars doesn’t have mineable, it seems Ceres should have mineable water- and if we know anything at all, a huge amount of mineable water.
And Mercury might have trillions of tons of water one could mine.
Though it seems, the Moon will have somewhere around ten of million of tons of mineable water {mineable at some point in time], and Mars will have tens of billion of tons of mineable water, and Ceres would have thousands of trillions of tons of mineable water.
And over a century of time, Venus orbit could need more than trillion tons of water imported. In first decade, millions tonnes per year, later decades billions of tons per year.
And Mars needs for settlements, to start with millions of tons and be using billions of tons of water per year within a decade or two.
And Mars could export to Venus, about 1/10th of it’s domestic water needs, to Venus orbit, and then Ceres, starts by shipping somewhere around a billion tons of water per year to Venus orbit.
If Moon only has 10 million tons of mineable water, it doesn’t export to Venus any significant amount. But if the Moon has a billion tons of mineable, it could compete with Mars.
When I was of certain age, not yet cognizant of Space-Time Dynamics and worm holes, and also living in a house without a fireplace, it was explained that at our house Santa used the back door. Ergo, prior to bedtime I made sure Mom and Dad left the back door unlocked prior to going to bed. At that age there was no need, waking up in the middle of a restless night, to check on the promise my parents had made. And I sure didn’t want to risk a bypass by being out of bed!
