This is literally a display of them minimizing debris by making the tension rods part of the second stage. It will burn up with the second stage instead of just staying in orbit. Everything you see in this video will eventually come back down

Indeed. Resource extraction would be the main focus. Also serving as the "gas station" of local space travel. Which given the vastness of the Jovian system could be mostly local.

Absolute flimflam. Wouldn’t be possible.

They don't charge the same prices everywhere, they will charge whatever each regional market will bear.

For example in Mexico it costs 1,100 pesos per month which is ~$60 USD.

I agree with your points OP. I think over the long term, the primary place of human habitation is going to be in orbital habitats (particularly O'Neill cylinders). However, Callisto is as you say one of the strongest candidates for a place for human habitation in the solar system - if not the strongest.

Callisto as the primary hub of the Jovian system seems like the most likely outcome. I think over the medium to long term, the Jovian system becomes the largest economy in the solar system - exporting tons of raw resources to other settlements across both the inner and outer solar system. It will likely get overtaken by Neptune eventually, but Callisto as THE economic juggernaut of the solar system for a period at least is not at all far fetched.

Can you suggest a better alternative for them, or provide one? One that works on mountains, in deserts, at the poles, in jungles, on oceans, in aircraft, etc.?

This is in everyone's interest though right? So surely some very basic rules could be agreed by both sides.. together.

From what I understand as a lay person this is correct. Mass is what causes warping of space time which in Newtonian physics is called gravity and thus the law of gravitational attraction. Gravity is an apparent force. Gravity is acceleration due to mass.

In which case he'd sell the company, deorbit the satellites and close it down, or abandon it and the satellites would come down shortly by themselves. In any case, the upside far outweighs any downside.

Oh sure, you mean in Countries where People are lucky if they earn more than 500.-? They for sure have 600.- for the Starter Kit and the 110.- per Month to waste even as a Community 💀

Jet engines mix the incoming air in a flow that feeds into the burning and compression for thrust. This loses efficiency quickly as you go past Mach2. Rockets use a combustion chamber that is sealed off and has a steady and controlled inflow of oxidiser that is mixed in an injector plate.

They are two very different processes. The additional weight to have different engines means you do not gain in terms of mass.

Super complex systems that can burn both ways are on drawing boards. And have been on drawing boards for 70s years.

Europa is a terrible place for human settlement anyway.

Well... Sometimes they do, if you think about air launch (pegasus and launcher 1) as jet powered first stages.

Also, the hybrid approach has been studied extensively, and usually it's just not practical. You can read up on the SABRE project.

Till he decides to fire them for tweeting unflattering things about him.

Not enough air, and it's full of nitrogen.

LOX is 1141g/L at its condensation point (~54K) and I think rockets make it even colder to increase the density a bit higher, while atmospheric air is only ~1.3g/L.

Compressing it at ~1000:1 would take some pretty epic equipment, and then it'd be way too hot.

Even if you somehow manage to sort that out while still having a launch TWR > 1, air is still only ~19% oxygen or so, meaning the fuel wouldn't be able to burn effectively.

Furthermore, the atmosphere gets even thinner within a few dozen seconds of lift-off, so you'd still need to carry oxidizer anyway - and the little bit extra it takes to get up to that point is far lighter and simpler than having the rocket itself run on atmospheric air for half a minute.

It's much more sensible to process it as much as possible on the ground, and load LOX into the rocket.

Having said that, companies that strap their small rockets to aeroplanes are technically already using atmospheric air for that phase of the flight - but the type of engine required is radically different, and those rockets have to be relatively tiny because aeroplanes can only carry so much mass.

Regardless of one's opinion of Musk, Starlink is far more than just him, with many hard working engineers making it happen.

Skylon is a British company trying to construct an air breathing SSTO. Apparently that's an open question.

Don’t get me wrong, the idea is good, the person behind it is a flighty teenage man with the attention span of a lobotomized goldfish

Nonsense. Rural villages have a single connection, which they share through local wifi.

Also not a physicist, but it seems to me like a lot of the models and terms we use to describe space and gravity assume a two dimensional plane of space for the ease of visualization. I get the impression that this often has the side effect of confusing the relationships between things like light, space, and gravity.

Air is mostly nitrogen. And they need a whole lot of 02 to mix with the fuel in the right ratio in order to get the proper thrust. It's just not that feasible in the few minutes they're even in the atmosphere

Highspeed Internet for the whole World which only People in first World Countries can afford 🤣💀

They're the same thing, really. Gravity is the effect of spacetime curving around a mass.
