If you're thinking of passenger service, perhaps it is a bit unattractive in the short term. No good launching and landing spots.
But for military use - think logistics. Rapid delivery of equipment to unusual places. This applies to civilian purposes as well. All kinds of use-cases for speeding up cargo.
The entire economics of Starship and rapid reusability was presented at the beginning of the Starbase work, way back when Hoppy was a thing. He's been sticking to the plan since then. You might want it to be fiction, but he's been very good at figuring out business plans to leverage his ultimate goals.
> But for military use - think logistics. Rapid delivery of equipment to unusual places.
Surely it's too fragile/explodey for military use - the whole thing's a very volatile fuel tank - could it survive being shot at, even a single high-powered rifle bullet (during landing, or even post-landing) without going boom?
It doesn’t have to be able to deliver in a combat zone to be able to deliver halfway around the world close to a combat zone. Or do you think the Hercules is worthless because it isn’t armored and doesn’t have weapons?
Many promises that never materialized or resulted in mediocre or bad products, from the Mars mission to the Hyperloop, and from Teslas dismal software and often promised, never materializing fully autonomous drive to the Cybertruck. Let's not go into the robot vapourware either...
Hyperloop is the only thing you listed that is accurate, although it was only a whitepaper + competition. It was open for others to pursue.
Tesla easily has the best vehicle software + OTA and has since the S in 2012. It still feels better than most new vehicles.
You can buy a Tesla (including Cybertruck) today that will do 95+% of drives with 0 intervention. It may not be 100% autonomous yet, but there isn't anything obvious limiting the last step.
The robots exist but are still being developed. Within 5 years, it is hard to imagine them not becoming super valuable within factory settings.
If you think Tesla is bad, you should look into GM or Ford.
There have been many accusations about sudden accelleration, but except for the Cybertruck's pedal-cover slide, there has never been a proven case of a Tesla autonomously accellerating into a crash. But these accusations come a lot, because people are always wanting to shift the blame away from themselves and the automaker seems like an easy target.
And yet SpaceX flies the most reliable rocket in history more frequently than anyone in the world has ever flown, takes astronauts to the ISS regularly, and does so for far less then any competition. Tesla changed the automobile from ICE to BEV in a way people wanted to buy and was practical as a replacement for any use, and created a charging standard so successful every US car company is switching to.
>And yet SpaceX flies the most reliable rocket in history more frequently than anyone in the world has ever flown, takes astronauts to the ISS regularly, and does so for far less then any competition
Yeah, after almost half a century, they passed 70s-era Soyuz numbers.
>Tesla changed the automobile from ICE to BEV in a way people wanted to buy and was practical as a replacement for any use
The magic of EV subsidies (for both Tesla and buyers).
>And the Mars missions so far are just delayed.
The magic of that statement is that it can be true at any point in the future!
The American people didn’t pay for the R&D if SpaceX, Musk did and then customers did. Customers (including the federal government) that saved millions on every purchase.
NASA gave SpaceX 400 Million just for the development of Falcon 9 and there is a video were Musk said SpaceX was bancrupt if NASA wouldnt have stepd in.
NASA also another 6 Billion upfront to SpaceX for Dragon and HLS.
So yes the american paid for the R&D of SpaceX.
SpaceX took the 'risk' but either succeeding or not in your main business is hardly a risk if you need to succeed anyway to have that business.
Yes, but recall that those contracts were made in a competitive marketplace where SpaceX was the lower bidder.
If not for SpaceX, the American People would have paid more to the ULA group for what has clearly turned out to be inferior results, since ULA has received far more money for far fewer services.
That's fun. Octopii rolls off the tongue though, doesn't it? Since we have survived both the Greek and Roman cultures, and have absorbed aspects of both into languages now widely distributed, I'd like to propose that we seed the path of a true lingua franca and declare the plural of octopus to be octopii.
It's no worse than inserting greek words (octopodes) into English language.
12am-5am is very quiet, at about 1 per hour. But the accident happened during the 10pm-12am time slot, which is not as busy as other times of day, but can still have workload spikes as evidenced by this situation.
You've described a space station, which three countries have already done independently (Mir, SkyLab, Tiangong).
But dropping rods from an orbiting platform makes no sense. There's a reason that "Rods from God" didn't pan out, and it has to do with orbital dynamics. Neither Bezos nor Musk can do it, because it actually doesn't work.
I doubt it was seriously considered at the time it was discussed. Space Stations are in orbit - the space battleship doesn't have to be, that is very significant.
Earth is spinning in a giant circle around the sun. Thats facts. "aiming an asteroid" is less of making a rock a missile - and a lot more of tug-boating it into the exact right spot, in the way of earth, so that earth hits the asteroid - not anything complicated like the asteroid hitting earth.
Any realistic space warship design will need propellant - sure you can avoid ground based interceptors and kill sats but it will eat into your propellant reserves over time.
You will need to replenish from somewhere & that somewhere might as well get nuked instead of the ship, rendering it useless.
> Space Stations are in orbit - the space battleship doesn't have to be
I mean, you did say:
> space battleship - one that never comes down to the surface, just sits in orbit.
So I think it's understandable for people to take that at face value.
Furthermore, if it isn't in orbit, then where would it be?
> and a lot more of tug-boating it into the exact right spot, in the way of earth, so that earth hits the asteroid - not anything complicated like the asteroid hitting earth.
From an orbital mechanics standpoint I don't think there's actually a difference. You're changing an orbit either way.
If I were holding earth hostage with my Space Battleship - I would sit in a lunar orbit. Also, I am not kidding about tug-boating - if I fly up, match an asteroids speed and velocity, why cant I just throw a tow strap on that, accelerate, and park it an area that only has to be accurate enough for a planet to hit it - I dont need to stop it, or have it flying at the earth, it only needs to be in the way, moving a little slower than the earth.
What if I make that the space battleship's job? What if a drone can do that?
Im not really worried about resupplying the space battleship holding earth hostage -> someone will "volunteer" to do that, bc they want to live life.
Ah, so by "orbit" you were talking about orbit around Earth specifically?
> why cant I just throw a tow strap on that, accelerate, and park it an area that only has to be accurate enough for a planet to hit it - I dont need to stop it, or have it flying at the earth, it only needs to be in the way, moving a little slower than the earth.
Again, from a high-level orbital mechanics perspective there is little difference between the two. You start with two non-intersecting orbits and you're changing one orbit to intersect the other at the same time and place. How you go about doing so is just a question of how much time/fuel you're willing to expend, for various values of "just".
That being said, assuming I'm interpreting you correctly what you propose is probably technically possible (e.g., change an asteroid's orbit to a slightly-larger-than-Earth-sized one), but it's also very fuel-intensive compared to skipping the "parking"/"in the way" part.
If you haven't tried it already I can't recommend Kerbal Space Program enough for experimenting with this kind of thing, especially if you are alright with playing with mods. Real Solar System (changes the in-game solar system to match the our real-life one) and Principia (replaces the simplified patched conics system KSP uses for orbits with n-body gravity) would be particularly relevant here.
I absolutely will check out Kerbal - I have done nothing more than thought experiments - which I'm sure is obvious, its obvious to me. I'm sure I am saying things exactly wrong - the idea is to save fuel and remove all of the difficulties that may arise with timing or aiming. Using more fuel is exactly opposite intent.
I may be confused but I dont mean a "larger orbit than the earth" -> I mean the exact identical orbit, the exact path that earth takes around the sun -> ahead (or behind, it does not matter) of where we are and instead of 365 days to circle the sun, the asteroid is moving at a rate that will take MORE days -> so the earth will smash into the asteroid, bc it can't do anything else. I dont mean "park" in the sense that I stop its movement, nor would I select an asteroid that has such an orbit that it couldn't be manipulated into position with little difficulty.
Like, imagine the solar system was a record on record player (I've never used one either) and the earth is on a line/groove - a choice asteroid is moving in the same direction on an immediately adjacent line/groove - the asteroid only needs to move onto the earth's groove (anywhere on that specific groove the earth occupies on the record works) and then the asteroid is then sped up or slowed down (not much tho) on that exact orbit -> either will result in a collision with earth.
The only real way to stop such activities is with spaceships. That is my entire argument - you are saying that is less feasible than making a missle out of an asteroid? I appreciate the explanation fr
Tbh, it wasn't until the game Terra Invicta that I really considered the solar system, as it actually is. That game has no other relevance to this particular conversation - good game, very different kind of 4x that I recommend but unrelated.
> I mean the exact identical orbit, the exact path that earth takes around the sun -> ahead (or behind, it does not matter) of where we are and instead of 365 days to circle the sun, the asteroid is moving at a rate that will take MORE days
Unfortunately that's not really possible. To a first approximation, Earth's orbit is a circle with the Sun at its center, and the size of that circle is determined entirely by Earth's orbital speed around the Sun. Assuming you're also in a circular orbit, if you move at Earth's speed, the size of your orbit will be the same as that of Earth's. If you move faster or slower, your orbit will be smaller or larger, respectively, unless you wish to continuously burn fuel to maintain your distance from the Sun. That's why I said the asteroid's orbit must be slightly larger than that of Earth's for an Earth-catches-up-to-asteroid-in-similar-orbit scenario.
Obviously things get more complicated once you consider non-circular orbits, but the end result is similar - you can't continuously hang out in Earth's path while moving slower than the Earth around the Sun without burning a stupendous amount of fuel.
> you are saying that is less feasible than making a missle out of an asteroid? I appreciate the explanation fr
I think it's more that I think that "making a missile" is likely to require less fuel since you only need to adjust the asteroid's orbit ~once (only need to get it on a collision course) instead of ~twice (get the asteroid on a near-collision course, then adjust it again for the "right" kind of collision).
I cant reply to your other comment - that is what I assumed you were saying but it does not make sense to me outside the process that naturally occurs - I'm assuming the suns gravity simply cant move objects of such different mass, at the same rate, and thereby the orbit and position changes accordingly?
The speed doesn't have to be much different - 366 days and earth will eventually hit asteroid - 364 days and it will eventually hit the earth.
Ahh, Im still having a hard time figuring out why that would take more energy - I'm going to be researching this all morning tomorrow.
> I'm assuming the suns gravity simply cant move objects of such different mass, at the same rate, and thereby the orbit and position changes accordingly?
Kind of? An object moving in a circular motion at a constant speed must have an acceleration towards the center of the circle of (velocity^2)/(radius). This means that two objects in the same circular orbit moving at different speeds must be experiencing different accelerations towards the center of the circle.
In the simplified case of orbits around the Sun, that acceleration towards the center of the orbit is due to the Sun's gravity. However, gravity accelerates everything at a given distance at the same rate. As a result, you can't have two objects solely influenced by the Sun's gravity that orbit around the Sun with the same orbital shape but moving at different speeds. You'd need something in addition to the Sun's gravity to pull that off.
> The speed doesn't have to be much different - 366 days and earth will eventually hit asteroid - 364 days and it will eventually hit the earth.
Sure. When I said slightly-larger-than-Earth-sized orbit, I really meant it. Kepler's third law of planetary motion states (approximately) that (orbital period)^2 is proportional to (radius)^3. Assuming I did my math correctly, if your orbital period goes from 365 to 366 days your orbital radius gets ~0.18% larger, which is roughly 274000 km increase over the radius of Earth's orbit. That would fit inside the Moon's orbit (~385000 km from the Earth)!
> Ahh, Im still having a hard time figuring out why that would take more energy
At least the way I was thinking, the short answer is that one alteration to an orbit is likely to be cheaper than two, especially if you aren't particularly concerned in what manner the asteroid eventually collides with Earth.

Canada also uses hand counted paper ballots and it works great. There's no need to make large-scale voting electronic, and I'd never trust it without major social institutions in place that can provide the kind of oversight we have with good old paper ballots.
Hard not to "blame the referee" when the supreme judge-kings in charge of the electronic voting system are openly partisan to say the least.
In fact, the issue of fair elections in Brazil has become background noise because of these so called "referees". They have usurped so much power elections are just theater at this point. It doesn't matter who wins because in the end it's the judge-kings who rule the country. There's no point in even discussing the matter until their fall.
That's perhaps not the best example of a stable democracy. Lots of people in Brazil mistrust the voting system, and they were pretty close to a coup d'etat after their last election, with polticians thrown in jail and so on.
Isn't that something we asked for? We keep asking for parents to parent their children instead of getting age verification laws, and that is what that looks like.
Hopefully not used as packaging for Oreos, because unless the fungus has been highly adapted to the substrate, the mycelium will try to grow into the food. Oyster mycelium won't be toxic, but I don't want my Oreos to taste like mushrooms.
Take meth for example, if someone can use it for only one hour a day is it a problem?
Who and what in your life is 16 hours of Instagram taking you away from?
Instagram is garbage by the way for any Meta people in this thread. I’m tired of not seeing anyone I follow because you’re putting ads and viral videos I don’t give a fuck about in front of me instead. No wonder it wastes 16 hours, scrolling through shit trying to find something from someone or something you follow.
Your app is literally useless for communicating or keeping up with anyone I follow.
Facebook died when it lost interest in being Facebook and wanted to become TikTok.
Instagram died when it lost interest in being Instagram and wanted to become TikTok.
Your products and company should be banned, and everyone on your board belongs in jail.
Starship's true purpose is to compete with airlines in trans oceanic flights.
Musk has said so many times but then he intentionally obfuscates it with all the Mars and Moon talk.
But remember that you heard this before it was widely realized to be true; Starship isn't about going to Mars. Starship is about going to China.
