It was a test flight of the rocket, too risky to put a multi-million dollar satellite on it. Normally they use a block of cement to provide a dummy weight, but that's boring.

That being said, the car is still better than a hunk of concrete, as the rocket was a test and it was going up regardless, I'm sure that now launches to space are getting cheaper, we'll be seeing more of that for better or worse

[Anonymous No.9515812]

>>9515677
>Is there a reason why we are not sending fuel to orbit instead of dummy payloads?
Please show me examples of actual in-flight refueling that has been done in space.

Fueling a rocket isn't like sticking a nozzle from the gas station into a hole in the side and stopping when it splashes out. And it also kind of depends on gravity for it to work properly. On top of that, many rocketry fuels (especially LOX) are cryogenic and have to be kept cold. And LH2 is a pain in the ass to keep around, not in the least because of how it behaves at liquid temperatures: one spin combination flips exothermically, just enough to go gaseous again.

So there's no standard for fueling connections, you have to constantly keep that shit cold, and I don't think we even really know how to do it yet.; Not that we can't do it, but it's just not that easy.

I don't see anything in your post that comes close to explaining why we aren't sending fuel to space using the extra capacity available. So it's hard, so what? Lots of things space-related are hard. Kennedy would have something to say about them being hard.

Putting fuel in a container and eventually getting it out of it is definitely doable even in space. It doesn't have to be liquid as there are solid fuels as well. And I bet all it takes to keep it cold is to wrap it inside some aluminum foil (to reflect sunlight).

Water (for drinking, coolant, radiation protection or whatever) would also be very much appreciated up there for future space projects. Hell, even comic books and random tools would be nice.

You seem to have a "cartoon" understanding of orbital physics. Even if you ignore the technical problems of refueling, then you've still got the problems of rendezvous. It's not like driving on streets up there, you are stuck in whatever orbit you happen to be in, and it takes a lot of energy to change orbits. (or a lot of time to wait for the optimum moment) You can't just take a right and duck into a fuel depot. And then there's orbital decay.

If you left a tank of fuel in orbit, you would have to not only match its orbit, but you would also have to find its little speck in the sky. And if you left it up for more than a few months, not only would it be a hazard to navigation that could hit something in another orbit (refer to the Iridium incident), but its orbit would also decay.

tl;dr: you don't leave a fuel tank in orbit unless you're about to send something else up soon that knows it's there and needs it

[Anonymous No.9516563]

>>9516519
The first US satellite was launched 60 years ago and it's still in orbit. Orbital decay is very slow once you go above 700 km. It's almost non-existent as we are talking about hundreds and even thousands of years depending on the orbit.

Why would it matter that it takes energy to change orbits? I would bet that it takes way less energy to go from orbit to orbit than from ground to orbit.

Finding a fuel tank would be the easiest problem in the world. ESA keeps a catalog of all objects larger than 10 cm in LEO and it doesn't seem to be a huge problem. We're talking about objects that are an order of magnitude bigger. I also bet you can calculate current position if you know where you left it and what the vector was. You could also put transponders and lights on the fuel tanks.

That's nice, but the Van Allen radiation belts start at about 500km. Most manned LEO is between 200 and 400km, where orbital decay most definitely is a problem.

You want to give a bomb to a baby... i mean a space station? Seriously, they had enough trouble with something going near it back in the first Dragon cargo launch, they sure aren't going to let you attach a big container of either fuel or oxidizer to ISS.

And there's one other thing... what kind of fuel? RP1, LH2, hydrazine, and many other fun things that you don't know about, so clearly you haven't read the book Ignition, which I suggest you google to find a PDF of it. You're just spoiled by being in a world where most small vehicles use a single type of fuel and get their oxidizer from the atmosphere.

And why exactly would it be a problem to have a fuel deposit in the Van Allen belt? It's not like we are talking about a manned gas station.
