Not totally defending SpaceX, but they have to consider what happens if Russia declares open fire their satellites. It would be complete devastation for the company and all of Humanity. So SpaceX has to drawn the line somewhere.

A few more long term probes space x and most private space travel is going to just evaporate one day. Starting the replacement for the ISS. Orbital debris is going to become a massive proplem. Maybe a moon landing.

That's not the only shenanigans, that's just one example.

Lots of internet space bros claiming the benefit of higher Isp lost by increased mass due to reactor weight. Let’s finally build one and fly it to settle this once and for all. My two cents is that the anti-NTR space internet camp is also in the “Starship solves all problems” camp.

I think it’s focused more on the type of close up we will have in 2030. https://www.space.com/apophis

That didn’t take long to show up

Its the one invader he can’t rightfully blame on him

It's approximately 35.71 adult, male corgis, provided they are not overweight. Also, Disapproving Corgis may add gravitas to the equation and therefore you would need fewer of them.

i get it but they specifically gave it to them for communications and humanitarian aid and they used it for their bomb drones, they still have it for coms as far as i can see they just did something to stop the drone control over starlink

NTRs are for getting stuff around the solar system more efficiently - though in many cases NEP would be better, I wish that was getting as much attention.

For interstellar travel though you want a fission fragment engine as a bare minimum, preferably fusion propulsion of some sort.

I’n sick and tired and I first read the title as “Nasa confirms 1000m meteorite slammed into Texas”

I was like oh well, GG

No. It was the size of 1/10th of an adult female giraffe, though, and weighed approximately 1/3rd of an adult hippo.

Complexity adds a diminishing returns factor the further you get down the tech tree. For instance, in the very early 1900s, a huge number of the tech advances were a result of someone figuratively tinkering in their garage. These days you often need the collaboration of large institutions or even nation states to continue those efforts.

We're also approaching the limits of material properties/chemistry. We're extracting just about all the useful work that is available by burning hydrogen in a rocket engine. There will always be improvements to be made but those will likely require large efforts for minor improvements. OFC, nanotube advances and such are also possible. But, those will tend to be fewer and farther between.

Tech advances will never stop. But the rate of change will likely slow down overall, maybe quite a bit. You will have the gamechangers like carbon nanotubes and maybe even fusion happening every once in a while. And those will be huge. But taking fusion for example. That might happen in 20 years. Or it might be 200 years.

That's not to say you shouldn't be excited about the future and advances and so forth. But maybe it wouldn't be the worst idea to temper the expectations a little bit.

Musk's shenanigans with Starlink/Ukraine has kinda sucked out all excitiment about SpaceX.

i am from medical physics. i can say as long as there is no solution to shield radiation, there is no way to reach planets with humans further away. so even frozen embryos or cryostasis will be useless, bcz they will be damaged and or destroyed through radiation.

another point is travelling distance. you can reach high speed. but keep in mind that you need the same time for braking speed down as for speeding up. and at these velocities you need big big shields even for the smallest objects in space...

so huh... will be tough. living on mars will be possible imo. needs 200 to 300 y imo.

2055 COCCY2 satellite breaks speed record 0.0955% speed of light. 2076 Bowwie Mars Frontier (🇺🇸 🇮🇳 🇸🇬) return would had planed by 2080 but failed. 2077 1e type-4 Galaxy found 2085 Wesel-radiation confirmed in supermagnetars 2098 landing on asteroid 2010ST3 changing trajectory and taking a piece home.

Yeah, I think the deep ocean is a decent corollary for space. ROVs are the future!

I think engines will advance allowing missions that are beyond our reach right now. But, I'm not bullish on large numbers of people spending long periods of time in space happening this century. Perhaps next century if we manage to get on top of all the looming issues and figure out fusion or something...

This thing was like half a meter big at most and most of it burnt up. We are not launching anything to space to find these, and we'll probably never will. Media trying to sensationalise some tiny meteorites again lately.

I imagine larger fusion powered spacecraft that are assembled and remain in space where they would be restocked and refuelled. These would take humans to the outer planets.

When I was a kid (1990) my dad got me a book called Space: The Next 100 Years. Every single prediction made was wrong lol.
