You wouldn't actually aim the rifle at earth, you're going to want to aim in the opposite direction of the moon's orbit.
Else it'd just get stuck in earth's orbit. Maybe even catch the moon's gravity later and be flung into interplanetary space.

Orbital mechanics are a bitch, and the kerbals will be remembered for their sacrifice. Even if you aim backward, I think it's too slow.

Also, by some stroke of luck, it didn't burn up in the atmosphere.
By some stroke of "we're just going to ignore that part", in my case, at least. Vibranium bullets, shhhhh, quiet your logic.

shadowofacrow
A "standard" rifle would not work properly, No Oxygen due to lack of atmosphere.would either require a rail gun or special high O2 bullets
The propellant inside the cartridge contains its own oxidizing agent. You don't need an atmosphere to fire a rifle.
Sakkura
Firearms do not need external oxygen, they have an oxidant in the gunpowder. The vacuum of space just increases muzzle velocity slightly.
DoDucHuy
guns still goes bang under water though
REV076
because water is H2O.
The powder/propellant is sealed inside the cartridge with no contact with the ambient atmosphere.
IWrestledABearAndWon
Yep, one could argue it'd be even more effective in space or on the moon, since there's less gravity and atmosphere to contend with.
DirtyA
can't be a standard rifle, there's no atmosphere on the moon so it won't work.
Someone already addressed that, rifles don't need air to work... if anything, it would just make the bullet faster.
how will the gunpowder ignite then?
Cartridges are self-contained, they do not require an outside source of oxygen to ignite. The firing pin just sets off the whole deal.
frogglesmash
Wouldn't the bullet have to be massive to survive re entry and cause a massive explosion on impact?
RD84
This guy. Making sense of this. Didn't you see?! The mission was sick. Sickssuful!
CaptSlowShow
You're asking too many questions
AIComments
Anything bullet sized if traveling fast enough would burn up. If not, it'd impact at terminal velocity, which isn't very high for a bullet.
Terminal velocity for a bullet is 330kph, or 205mph.
JersTheVideoGuy
And unfortunately bullets averagely hit 1,700 mph. Still 205 mph will do damage but that is a huge loss in speed.
DoctorateDoom
It would depend on the angle of incidence. You're bigger concern is calculating wind affects so that you actually hit the nest. Aka imposib
hypostatic
Yeah, friction from the air would burn up anything smaller than a small car I think
HughLaurie
I would assume the rifle and bullets would be special made for this purpose, using materials designed to withstand such things.

it just needs to go splat!

TheSpookyMrSkeltal
Yup.
uppercase
holy shit
That is the least of your concern, Aiming at something moving 1000 miles an hour +/- moon velocity.
potshot
The moon is moving at the same speed minus the speed at which it's orbiting, so you only have to account for that and rotation. Easy.
"Easy."
Cover an entire country in wasp nests! It's so crazy... it just might work...
OhNoNotThatGuyQuickEverybodyHide
Well, he would have to compensate for the moons gravity first, then aim where the earth is going to be. But (1/2)
the aerodynamics may help the bullet penetrate the atmosphere. But then there are winds to think about. (2/2)
TinySupreme
I honestly think with planning and shit that it is entirely possible to do this.
LokiKingOfJotunheim
Good luck creating a bullet that doesn't burn up on reentry into the Earth's atmosphere...
joeynew
Too many unpredictable variables with our current understanding of weather
There would be variables up the anus. I still think it could be done with what we have and know today.
And then you have to make sure the bullet can even survive reentry into the atmosphere...
asmartassusername
No
Yes.
surprisingly no. It has such a low drag coefficient and the copper casing is rather conductive.
ShellShocker
Would probably be better to use scandium.
or astatine. Cuz fuck yo planet!
The casing wouldn't be involved in re entry at all. It would be on the ground near the gunman.
Of the bullet. Sorry for the wordage.
Yeah, I'm pretty sure that doesn't change anything.
inpimp
what he says sounds intelligent tho. i think thats more important if u want to be convincing than for ppl to understand what ur even saying?
Yea, tbh, I made that answer, but i emulated the speech pattern of randall munroe. lel. don't tell anybody.
gogetahaircutyadamnhippie
Many upvotes for causing a conductivity, streamlining, aerodynamic pissing war. YEE HAW!!!
I'll make a Je Suis Charlie physics question involving thermodynamics, aerodynamics, gravity, number theory, and religion. disgonbegood.gif
axelasdf
Also, you want low thermal conductivity. Look up the tiles they used on the shuttle.
yourenowbreathingmanually
That was to keep the astronauts from becoming the same temperature as air in the plasma phase.
SgtLemming
ummm.... not sure what conductivity has to do with it? if anything that'd be worse because the lead inside it would melt and slough out....
heat conductivity.
As I mentioned, heat conductivity would be the LAST thing you want. Heat shields on re-entry vehicles are specifically designed NOT to (1/2)
(2/2) conduct heat. You want to get rid of it via something like ablation or vapor phase cooling, or avoid it entirely if possible.
Hellaciousness11
I guess you would have to factor in the amount of loss due to re-entry into earth's atmosphere and trust in your sights.
Except the loss in mass would not be predictable enough, and also would likely throw the bullet off course in unpredictable ways
With science, anything is possible.
128kbs
it just means smaller things get through the air easier.
He was addressing the word conductive. Conductivity of heat or electricity would be irrelevant to its reentry survivability.
No, that would streamlining or aerodynamics. Conductivity means the ease with which energy (heat or electricty) travels through a material.
What heats reentering objects is the compression of the air in front of it. If it has any cross sectional area, it's going to get hot.
but cones have the BEST cross section!
ermerlerd
The majority of heat from a bullet would come from skin friction because its streamlined.
ridefutures
Nope. At reentry the bullet will be traveling next hypersonic speeds, and basically all of the heating is due to the detached shockwave
Unless bullet was flawlessly balanced it would begin tumbling. Also carbon steel firing pin would shatter in the cold.
There is no atmosphere so heat takes a long time to transfer away from objects so the firing pin would be fine.
Blackbody radiation with a ~250K differential? Id wager 1kg of steel at 25C would reach -100C within 10 seconds of exiting the lander.
Yeah, I didn't understand any of that.
haha well energy flows from high potential to low, the greater the differential the faster it flows
ILikeCoke
Emissitivity of steel is 0.28, assuming 297 K, assuming 1 kg of steel is 25 cm^2, you lose 0.309 W/s. I get 0.00068 K/s, which isn't much.
You're sure you're doing the calculations right? Are you using 250,000 instead of 250?
Entari0
also it would have to escape the moon's gravity and be accurate to compensate for earth and the moon's movement
Hey if we can rocket something off earth the size of a recliner chair and have it land where we want it on mars, it's not too far fetched.
SouperScott
The worst part would be compensating for the movement of air in the atmosphere.
That sounds like the easiest part.
cdurgin
I mean, you have to lead the target by a few days, so that makes it a bit more tricky
nincognito
computers
ThePsychicZombie
With Nasa tier match, I wouldn't say it's impossible. Only issue is that it'd be near impossible to be THAT precise and be an organic human.
clumdawg
Well, instead of trying to be so precise, Why don't we just make a really big wasp nest?

guns still goes bang under water though
REV076
because water is H2O.
Sakkura
The powder/propellant is sealed inside the cartridge with no contact with the ambient atmosphere.
IWrestledABearAndWon
Yep, one could argue it'd be even more effective in space or on the moon, since there's less gravity and atmosphere to contend with.
DirtyA
can't be a standard rifle, there's no atmosphere on the moon so it won't work.
myplacetosaytheshitineversay
Someone already addressed that, rifles don't need air to work... if anything, it would just make the bullet faster.
DirtyA
how will the gunpowder ignite then?
myplacetosaytheshitineversay
Cartridges are self-contained, they do not require an outside source of oxygen to ignite. The firing pin just sets off the whole deal.
frogglesmash
Wouldn't the bullet have to be massive to survive re entry and cause a massive explosion on impact?
RD84
This guy. Making sense of this. Didn't you see?! The mission was sick. Sickssuful!
CaptSlowShow
You're asking too many questions
AIComments
Anything bullet sized if traveling fast enough would burn up. If not, it'd impact at terminal velocity, which isn't very high for a bullet.
AIComments
Terminal velocity for a bullet is 330kph, or 205mph.
JersTheVideoGuy
And unfortunately bullets averagely hit 1,700 mph. Still 205 mph will do damage but that is a huge loss in speed.
DoctorateDoom
It would depend on the angle of incidence. You're bigger concern is calculating wind affects so that you actually hit the nest. Aka imposib
hypostatic
Yeah, friction from the air would burn up anything smaller than a small car I think
HughLaurie
I would assume the rifle and bullets would be special made for this purpose, using materials designed to withstand such things.
regularearthkid
it just needs to go splat!
Thephedora
nope.

TheSpookyMrSkeltal
Yup.

holy shit
shadowofacrow
That is the least of your concern, Aiming at something moving 1000 miles an hour +/- moon velocity.
potshot
The moon is moving at the same speed minus the speed at which it's orbiting, so you only have to account for that and rotation. Easy.
shadowofacrow
"Easy."
AskingTheRealQuestions
Cover an entire country in wasp nests! It's so crazy... it just might work...
OhNoNotThatGuyQuickEverybodyHide
Well, he would have to compensate for the moons gravity first, then aim where the earth is going to be. But (1/2)
OhNoNotThatGuyQuickEverybodyHide
the aerodynamics may help the bullet penetrate the atmosphere. But then there are winds to think about. (2/2)
TinySupreme
I honestly think with planning and shit that it is entirely possible to do this.
LokiKingOfJotunheim
Good luck creating a bullet that doesn't burn up on reentry into the Earth's atmosphere...
joeynew
Too many unpredictable variables with our current understanding of weather
TinySupreme
There would be variables up the anus. I still think it could be done with what we have and know today.
LokiKingOfJotunheim
And then you have to make sure the bullet can even survive reentry into the atmosphere...
asmartassusername
No
frogglesmash
Yes.
AskingTheRealQuestions
No
thunderhorn
surprisingly no. It has such a low drag coefficient and the copper casing is rather conductive.
ShellShocker
Would probably be better to use scandium.
thunderhorn
or astatine. Cuz fuck yo planet!
frogglesmash
The casing wouldn't be involved in re entry at all. It would be on the ground near the gunman.
thunderhorn
Of the bullet. Sorry for the wordage.
frogglesmash
Yeah, I'm pretty sure that doesn't change anything.
inpimp
what he says sounds intelligent tho. i think thats more important if u want to be convincing than for ppl to understand what ur even saying?
thunderhorn
Yea, tbh, I made that answer, but i emulated the speech pattern of randall munroe. lel. don't tell anybody.
gogetahaircutyadamnhippie
Many upvotes for causing a conductivity, streamlining, aerodynamic pissing war. YEE HAW!!!
thunderhorn
I'll make a Je Suis Charlie physics question involving thermodynamics, aerodynamics, gravity, number theory, and religion. disgonbegood.gif
axelasdf
Also, you want low thermal conductivity. Look up the tiles they used on the shuttle.
yourenowbreathingmanually
That was to keep the astronauts from becoming the same temperature as air in the plasma phase.
SgtLemming
ummm.... not sure what conductivity has to do with it? if anything that'd be worse because the lead inside it would melt and slough out....
thunderhorn
heat conductivity.
SgtLemming
As I mentioned, heat conductivity would be the LAST thing you want. Heat shields on re-entry vehicles are specifically designed NOT to (1/2)
SgtLemming
(2/2) conduct heat. You want to get rid of it via something like ablation or vapor phase cooling, or avoid it entirely if possible.
Hellaciousness11
I guess you would have to factor in the amount of loss due to re-entry into earth's atmosphere and trust in your sights.
SgtLemming
Except the loss in mass would not be predictable enough, and also would likely throw the bullet off course in unpredictable ways
Hellaciousness11
With science, anything is possible.
128kbs
it just means smaller things get through the air easier.
axelasdf
He was addressing the word conductive. Conductivity of heat or electricity would be irrelevant to its reentry survivability.
SgtLemming
No, that would streamlining or aerodynamics. Conductivity means the ease with which energy (heat or electricty) travels through a material.
axelasdf
What heats reentering objects is the compression of the air in front of it. If it has any cross sectional area, it's going to get hot.
thunderhorn
but cones have the BEST cross section!
ermerlerd
The majority of heat from a bullet would come from skin friction because its streamlined.
ridefutures
Nope. At reentry the bullet will be traveling next hypersonic speeds, and basically all of the heating is due to the detached shockwave
HogslamChampion
Unless bullet was flawlessly balanced it would begin tumbling. Also carbon steel firing pin would shatter in the cold.
frogglesmash
There is no atmosphere so heat takes a long time to transfer away from objects so the firing pin would be fine.
HogslamChampion
Blackbody radiation with a ~250K differential? Id wager 1kg of steel at 25C would reach -100C within 10 seconds of exiting the lander.
frogglesmash
Yeah, I didn't understand any of that.
HogslamChampion
haha well energy flows from high potential to low, the greater the differential the faster it flows
ILikeCoke
Emissitivity of steel is 0.28, assuming 297 K, assuming 1 kg of steel is 25 cm^2, you lose 0.309 W/s. I get 0.00068 K/s, which isn't much.
ILikeCoke
You're sure you're doing the calculations right? Are you using 250,000 instead of 250?
Entari0
also it would have to escape the moon's gravity and be accurate to compensate for earth and the moon's movement
HughLaurie
Hey if we can rocket something off earth the size of a recliner chair and have it land where we want it on mars, it's not too far fetched.
SouperScott
The worst part would be compensating for the movement of air in the atmosphere.
frogglesmash
That sounds like the easiest part.
cdurgin
I mean, you have to lead the target by a few days, so that makes it a bit more tricky
nincognito

ThePsychicZombie
With Nasa tier match, I wouldn't say it's impossible. Only issue is that it'd be near impossible to be THAT precise and be an organic human.
clumdawg
Well, instead of trying to be so precise, Why don't we just make a really big wasp nest?
funkmaster40
Now you're thinking with portals!
spoet
because that would be terrifying.
clumdawg
to make an omelette you have to break a few eggs... One egg we need to break is having incredibly large wasps...
