Imagine a future in which our society is secretly run by a super AI. We still hold elections, except everyone elected to a national office is secretly launched into the sun. The rubes still think their beloved grifters are in charge, the corporatists believe their lobbiests are hard at work (they've in fact also been launched into the sun), and we get stable government out of the deal. The AI programs the guidance systems of any rich douche bag "space tourist" into the sun as well.
Some people find out about this murderous AI, but then look around and shrug and go back to their lives.

Yeeting them into the Oort Cloud requires less propellant.

It's even less expensive to just dump them on an active terrestrial lava flow.

It's quite a lot harder to launch a rocket into the sun than it seems. You have to overcome the angular momentum of the Earth's orbit. Still, I think our billionaires are worth the extra effort.

I'm still willing to serve as World Dictator and bring about peace through a series of population culls.  All the people of the world have to do is ask.

Tourist launches are a tiny smidgen of what what we do day-in-day-out for serious business. I know it's hep and cool to rail against the "wealthy enough to piss away billions" crowd, but that's really a fart in a whirlwind.

Wake me when it gets to be a "Princess Cruise Line" level of consumption.

And if the more-money-than-sense nitwits want inadvertently make human space travel safer and cheaper, then they can go ahead with their early adoption strategy.

Yeah, why bother with aiming for the sun? Why not just aim for "not earth", and then vent oxygen?

But YOU should feel bad because your POS commuter only gets 25 mpg while getting you between your 3 minimum wage jobs. Maybe you should give up meat or something.

It is much easier to eject something from the Solar System then to send it go the Sun. So we'll just give them a push towards a "nearby" black hole.

Hell, you don't need to hit escape velocity, just the wrong re-entry angle will do.

Total rocket launches per year are in the range of 70. And they last a few minutes at most.  There are approximately 45,000 airline flights per year and they last hours.

Yeah trying to stir up outrage against tourist rockets is like feeding 100,000 people per day and stirring up outrage about one pet shrew because it eats its body weight in food every day and people only eat around 1/50th of their body weight per day so the shrew is as bad as 50 people.

Only sensible comment in the thread regardless of what anyone thinks of billionaires.

Reminds me of an article a few years ago complaining that wireless phone chargers are going to contribute to climate change because they're less efficient than a plug.

You can't actually launch people into the sun.  They'd explode in the Corona.

In Kerbal Space program, I was able to launch to the sun by slingshotting over one of the other planets. Then I got bored and used infinite fuel, and just launch shiat at the sun with my god powers.

With the attitudes around here I'm surprised centrifugal launch for space tourism hasn't been discussed.   Less rocket propellant, and I'm guessing fewer return trips, without the need to get to the sun.

It's even cheaper to glue them underneath a rocket that's launching something useful into space.

I kid, I kid.

We need to develop better ways into space and after a half century of government work through NASA, the Air Force, and the Navy, there is enough space knowledge and space infrastructure for the private sector to work.

Get back to me in 20 years and tell me how a bunch of rich fakrs habits  don't affect anything.  If you can still suck enough air out of the atmosphere to say it.  And it's already clear that plenty of humans are narcissistic enough to get on a rocket and fly "away," no matter how much it costs, or how many resources it wastes.  It's a growth industry.

It's pretty clear that rich farks habits  DO  affect everything.   Right down the line.  They take more, you take more.  Their standard of what is acceptable to have goes up, yours goes up.   Or didn't you notice, there in your gated community?  You're just doing what everybody else does!

Physics says no.  Currently, the most likely 'better way into space' involves making the rockets reusable as Space-X has shown.

The fuel use per trip isn't going down, so as costs drop the amount of fuel used increases.  However, so long as we're using liquid hydrogen and oxygen, and getting those via 'green' power, the pollution cost is very small.

There is pretty much no hope of something like a space elevator happening on Earth - though I'd still like to see people working on it just in case.    Rail gun launchers aren't a practical solution, either.  If you want off the Earth, it's rockets and rocket fuel.

You are correct, I meant per day.

As far as I understand it the heat of reentry is a result of spacecraft using the atmosphere as a "free" brake.

If that's accurate the we could use fuel to slow down and come in slower and there wouldn't be much heat at all. That's expensive, but if reentry heat ever really became an issue we could do it.

But then you would have to burn even more fuel to launch all that braking fuel into orbit.

It's turtles all the way up.

Set up a source of fuel in orbit that doesn't have to be lifted out of Earth's gravity well.

LOX, LH2 from Luna, the belt, or elsewhere, or Methalox from Mars.

The distances are longer, but the energy cost to put a kilo of stuff into LEO is lower than launching it from Earth for one whole helluva lot of places in the system.
