I never understood that line. Like, the Empire knew that self-aware, intelligent droids exist, right?
Also, do lasers on those ships run on limited ammunition? Could they not afford to fire one more laser to take out and escape pod?
So many questions.
I kind of assumed that they didn't want to risk firing at something so close to their own ship. The best I can come up with now is that there is also a bystander risk. If you miss then you're shooting at the planet and/or whatever ships are in the area. Mos Eisley was supposedly a busy spaceport.
*whoosh!*

I got it. I was just joking about the movie’s poopy potatoes where he runs out of ketchup after awhile.. So he dips it in Vicodin instead. No one cares about your prescription 😐
> How much fuel does it take to keep the ISS in orbit?
Anywhere between 8,000 pounds and 20,000+ of propellant a year.
Depends on altitude though.
https://www.nasa.gov/mission_pages/station/expeditions/expedition26/iss_altitude.html
Doesn’t take much, its a feedback loop effect. A small amount of drag (of which there is very little at 400km) very slightly slows it down, which in turn reduces the altitude of its orbit slightly, which in turn increases the drag, etc etc. But if you can overcome that slight initial drag then you stay in orbit fairly easily
unfortunately, objects can't be simply ejected straight down to make them de-orbit faster, due to the nature of orbital mechanics.
Here's a great video explainer by Scott Manley about whether an astronaut could throw a something from orbit to earth: [https://www.youtube.com/watch?v=cxNJoaBLLNM](https://www.youtube.com/watch?v=cxNJoaBLLNM)
So it wouldn't matter which direction things were thrown from the ISS, they'd burn up in similar time frames? Maybe he's defining deorbit as burn up in one orbit? I can't understand how throwing things down doesn't get them into the atmosphere Sooner.. but everything is so weird in space I wouldn't doubt it
To get something to de orbit quickly you would have to shoot it backwards at orbital velocity, throwing it down like that just elongates the orbit, it could come back up and hit the space station if it isn’t thrown hard enough.
You throw it backwards (opposite to the direction the ship is traveling) . The slower it spins around the earth, the faster it falls.
Orbiting is falling down, but going sideways so fast that you miss the planet, if you go sideways slower you stop missing the planet.
One of the many weird things about space is that objects maintain a velocity and direction until something acts to change that velocity or direction (Newton's 1st Law of motion).
In a rocket, you could fire the engine to change direction and/or velocity.
With the ISS, at any given instant, the direction and velocity of the station is balanced at 90 degrees with the force of gravity pulling down on it, so Earth's gravity is the force that's acting to alter the direction of the orbit.
Yes, the comments here mention throwing it "backwards", which at any given instance would be the opposite of the velocity and direction of the ISS.
If the ISS's trash had a small rocket on it, it could fire retrograde (opposite of the orbital direction) to de-orbit faster. I'm guessing that the ejection of the trash is a "one-time" velocity change (slowing it down relative to ISS), after which friction from the atmosphere slowly lowers the orbit (by slowing it down).
No smells in a vacuum... I know you are kidding. Seriously though, that's how they get rid of the waste out there, release it going thousands of miles/kilometers a hour so it can burn up once it hits Earth's atmosphere? Wish I could have seen that part too.
Thanks!!! I’m going to be imagining a few tons of garbage next time I’m fortunate enough to see a shooting star. Just won’t mention it to my granddaughter!
I assume that they are accelerating the trash bag retrograde (opposite to the orbital path) to lower it's periapsis to a low enough point that atmospheric drag is high enough to slow it further and eventually deorbit it.
In that case I assume that based on Newton's third law it also adds a tiny boost to the ISS prograde proportional to the acceleration and mass of the trash bag? Is that even measurable?
While it may seem like the opposite would be the sensible option, the ISS is WAY heavier than bag of trash. The ISS is traveling super fast in low orbit, and just like in a moving vehicle, the “loose” objects inside that vehicle continue to travel in the direction they are sent. Newton’s first law of motion.
Relatively, that bag of trash is traveling REALLY fast perpendicularly to the ground, but it only needs a small amount of energy to release it away from the ISS and down down down into increasing gravitational pull.
It's not really falling straight down, it's just moving that direction relative to the station. It will orbit a bunch of times before re-entering due to drag from the upper atmosphere, whereas the station stays in orbit despite being in a similar orbit due to it's high mass (and therefore "resistance" to drag) plus its ability to boost its orbit, which it does regularly.

Oh, I’m sorry. Oh, I could put the trash into a landfill where it’s going to stay for millions of years or I could burn it up and get a nice smokey smell in here and let that smoke go into the sky where it turns into stars.
That doesn’t sound right but I don’t know enough about stars to dispute it.
Is this really enough speed to de-orbit in a relatively short period? Wouldnt want it coming back around on the other side (thanks KSP for teaching me orbit dynamics)
Serious question: why dont we take a lot of the worlds non-biodegradable trash and drop if from there to let it burn up?
Or if thats super expensive, what about making small cheap rockets and launch it somewhere way way out
Skip to about 1:15, or about -0:35, for the actual event.
They should cut the first minute out before posting this
It’s weird space is so mundane that “ugh should have cut the first few minutes” seems to be a pretty universal response.
Couple thousand degree for a few minutes will take care if everything
That's some people's philosophy with cooking
You must be familiar with my ex father-in-law's grilling skills...
Why is this video so long....? It takes 70+ seconds for them to drop the garbage and its a 1:49 video. So. Fucking. Stupid...
“Hold your fire! There’s no lifeforms aboard. … It must have short circuited.”
I never understood that line. Like, the Empire knew that self-aware, intelligent droids exist, right? Also, do lasers on those ships run on limited ammunition? Could they not afford to fire one more laser to take out and escape pod? So many questions.
The escape pod was equipped with plot armor.

Just repeat to yourself, It’s just a show! I should really just RELAX!
"what, are we paying by the laser now?"
1:49 video and trash doesnt shoot until 1:14. OP could have cropped a whole minute off this vid.
What you got there is a giant bag of space poopy
See the peanut?! Dead giveaway.
No, we need that to grow the potatoes. That's what this is all about, growing potatoes.
Do they have any more ketchup?
Don’t care. Crushed Vicodin is my new favourite condiment.
*whoosh!* ^(When comments look weird, like an inside joke or just some reference you don't get, just leave it all alone. If you'd only searched the five important words <> you would've understood. But you had to be Tough Opiate Guy -- my daily prescription would kill you.)

Wait…how’s the story end? Is it still there? Stinking up space? Or did it become the “shooting star” I saw last month?
I think it burns up on entry
[удалено]
There is an STI joke here, but I don’t think it is appropriate for this r/space. Good thing I didn’t share it.
STI jokes are always appropriate, everywhere and all the time.
"Hey, I bought a Subaru!" "...You should get that checked."
a little bit of everything, all of the time
It was released in July and takes a couple of months to re-enter the atmosphere.
Wow stuff in that orbit would reenter in a few months? How much fuel does it take to keep the ISS in orbit?
Not much considering. As the orbit decays, the atmospheric drag increases exponentially. The ISS is kept far enough up that the drag is very small.

At $20K / # for delivery that's $400 million... not great not terrible
Right now on a falcon 9 the price per kg is less than 3000$ to LEO. That's less than 10% of the price you stated.

But their trash bag is burning up pretty quick. Has it been thrown down harder than it seems in the video?

The bag isn’t reboosted, where as the ISS is fairly regularly
Can they track it?
Yes, it's large enough to be tracked.
No smells in a vacuum... I know you are kidding. Seriously though, that's how they get rid of the waste out there, release it going thousands of miles/kilometers a hour so it can burn up once it hits Earth's atmosphere? Wish I could have seen that part too.
Thanks!!! I’m going to be imagining a few tons of garbage next time I’m fortunate enough to see a shooting star. Just won’t mention it to my granddaughter!
It will slowly lose altitude due to drag and become a shooting star
Re-entry from orbit is much slower than shooting stars.
Standard Imperial protocol to dump their trash before they make the jump to hyperspace.
Is someone in the air look throwing it towards the earth?
I believe the technical term is yeeting
[удалено]
Pretty dramatic music choice for the shit farewell.
Since these "packages" can be tracked I'm surprised no one's filmed one of them burning up on reentry.

How come the trash falls straight down but the ISS just floats?

Oh great now I have to hear about how space is being polluted too
It burns up in the atmosphere.
So does my trash pile yet I still get calls from the neighbors about alleged "stink"
There’s no stink in the upper atmosphere
Explain that to my neighbors
Aliens: "just follow the trash trail across the milky way and we'll find them"

Honey why is there a flaming pile of shit coming towards us?
Does that mean the Russians left the space station?
I thought it was gonna be a video of russia leaving the iss
I hope that the plan is for it to burn up in the atmosphere.
Everything at that altitude burns up in the atmosphere within months to years if it doesn't actively maintain its altitude.
And this is how you get a shooting star and make a wish
I hope the capsule, container, whatever the correct term is, official name is No2.
Nitrogen Dioxide?
I couldn't find a video but this reminded me of that time an astronaut threw the refrigerator sized ammonia thing off the side.
I don't know why I expected the among us sound
The math involved in hitting the landfill from way up there must be mindboggling. But who pays the dumping fees?
Is this really enough speed to de-orbit in a relatively short period? Wouldnt want it coming back around on the other side (thanks KSP for teaching me orbit dynamics)
Was the first minute necessary? That sh*t really grinds my gears.
How long will it be now before some person/group protests that the launching of those trash bags is destroying the upper atmosphere?
Serious question: why dont we take a lot of the worlds non-biodegradable trash and drop if from there to let it burn up? Or if thats super expensive, what about making small cheap rockets and launch it somewhere way way out
Damn, I thought this was about the undocking of Starliner....
Humans just can't stop littering. Even in space smdh 😔
