@@IndronilAnik Well, if spaceships in the future could constantly accelerate and decelerate at 1g, if my math is right, it would take only 140 hours to get to Callisto. The 1g acceleration solves the problem of gravity on spaceships and it is fast, so a win win. Hopefully this will eventually be possible.

Obviously, small nuclear reactors would be required to power outpost and eventual colonies on Callisto-- especially during the more than 8 days of night. It should be easier to shield habitats on Callisto from excessive radiation and micrometeorites-- than on the Moon and Mars-- since all you have to do is fill up a bag of water surrounding the habitat with water just a few meters thick and then allow it to freeze into protective water ice. Large inflatable habits (biospheres and bio-tori) should be particularly easy to deploy since the external walls can be easily shielded with surrounding water bags that quickly freeze to ice. Biospheres manufactured on Earth and deployed to the surface of Callisto could be up to 50 meters in diameter (if inflated with the same atmospheric pressure that exist on Earth)-- large enough to accommodate a large swimming pool, basketball court, or tennis court in the top half of the biosphere under the biodome. There might even be enough room within the upper half of the sphere to fly around with wings underneath the 25 meter high biodome.

[@richardconway6425]

Yes, loads of good points there. Having loads of water around seems like an exceptionally good thing, quite a luxury, because it would, as you say, be very useful for protecting the astronauts in their habitats and workplaces. This would be in addition to all the other essential uses for water, like drinking, washing, splitting to make rocket fuel, and oxygen to breathe. The two most important things for space exploration - water and power.

[@AlmostEthical]

It would be easier just to send AI and access their sensory data. Humans are simply not sustainable in space - radiation, gravity, air, feeding, wastage ... and none of these have any margin for error. Scott Kelly showed how even in the ISS, which is largely protected by Earth, a single year deeply impacts human bodies. This was a super fit and healthy astronaut - far more robust than most of us - and he needed a long period of rehab on Earth afterwards to recover. As you noted, the mental stress for long distance human explorers would be far greater.

[@TylerMillhouse]

Great video! It's also worth considering the delta v requirements of getting to and from Callisto compared with the other Galilean moons. It's surprisingly difficult to get around there due to Jupiter's enormous gravity well.

[@condor5912]

I mean it depends. If you can just enter in orbit around Jupiter, and send a probe to Callisto from the orbit, it might, just maybe, be less difficult than you might think.

[@davidhollenshead4892]

That gravity well would also allow space craft to use it to accelerate ...

[@TylerMillhouse]

@@davidhollenshead4892 Unfortunately, a gravity assist from Jupiter would only allow acceleration relative to the sun, not Jupiter or its moons. You could get gravity assists from the other moons, but that means a circuitous route in a highly radioactive area of space.

Crazy idea here but what about crashing the Jovian moons into each other to create something with a little more mass and gravity? It would better hold onto an atmosphere and better sustain humans. For obvious reasons I suggest calling this new moon Minerva.

wow it is actually crazy :D this would be a great sci-fi film but it is defiifelly impossible for non type 2 civilization and might not even worth it. But it was cool to think abouth it thanks :)

The moons would also take millions of years to cool of and merge after the crash though, and by that point I’m sure we’ll have the technology to solve the problem of gravity and radiation

Hey whats up bro been a while i missed watching you man!

[@andreasbauer8668]

You overlooked a couple of really important known facts about that moon: it has basically no atmosphere. That means a spacecraft arriving from earth with high velocity will have to use propulsion to cancel out that velocity and land on the surface. THAT IS A REALLY BIG PROBLEM because it severely limits the payload that can be transported from earth. That is why on Apollo the lunar module was constructed in a very flimsy way and the whole mission took only 3 astronauts and yet needed the biggest ever constructed rocket (Saturn V) to make the mission possible. Human Mars exploration is within the reach of current propulsion technology because of distance and atmosphere. Callisto will have to wait until a breakthrough in propulsion occured.

[@goodguy2627]

16:48 Light needs 30 to 50 minutes...? That’s almost 70% impreciseness / tolerance. Where did that come from? The speed of light is a constant. Does the distance to earth changes with +/- 35% for some unknown reason?

[@sonicvenom8292]
