I've sent plenty of cubesats up

even high schoolers have done that

it is tracked by NORAD

ad we get the radio signal back from it

anything you want, sensors, etc.

well it is exactly where the orbit predicts it

it had my secret message in the radio signal, that only i knew

and when we point the antenna at that orbital location we get the radio signal

but no anywhere else

right where it was launched into

and it moves fast

viewing window is only 10 min b/c of the horizon

exactly as predicted by orbital math

@jeremy what units of sturdy woudl you like? tensile strength, modulus, safety factor?

calling someone a liar is not a valid argument

b/c that can be used against you too

@jeremy radiation heat transfer

avg radiation sink temp is 4K

(4 kelvin)

ya it's cold

but if your'e generating heat you'll be above that

or if the sun is hitting you, you'll be above that

or if you're near a planet, that will send IR yoru way

@jeremy depends on how much thermal mass is there, and if it has radiators and whatnot

when the sun hits it, it gets up to about 60 deg C or so

b/c only part of it is in teh sun

Yep our have temperature sensors on them at various places

that's the environment

not the object itself

the object doesn't change temp that much

when you cook a turkey does it get up to 350 F on the inside?

about 60 degC at the worst

and -10 deg C at the worst

it's always close to earth though so that is a source of warmth

it's never in that environment

in low earth orbit it's not that cold

in deep space it woudl be taht cold, and they require heaters to stay warm enough

like the pluto new horizons craft

i thought you were talking about space

ok well in low earth orbit the environment is on average a radiation sink temp of about 250 kelvin

yes that's right

depends on teh design, some have more surface area than otheres

that's not much

your car engine ismuch worsse

and that's just an aluminum block

yes!

we use a "thermal vacuum chamber"

produced vacuum and cold tempertaures, with a shroud that surrounds the wall, fileld with liquid nitrogen

and an oven to make the higher temperature

well there are a lot of launch vehicles

latest ones are from RocketLabs

but spacex does launch some

the launch provider who puts it in their launch apparatus and fairing

@der fuhrer's face i doubt they'll ever go for mars

no profit

yep

yes

we programmed the radio

no i'm aware of magic tricks and illusions

yes b/c i am not set up in a particular viewing seat, like what david copperfield did

he rotated the stage to a differnt place

if you viewed from off that stage, the statue didn't disappear

well by that logic you should be suspicious of lots of things

how do you know your mom is your mom? how do you know your name is what it is? how doyou know the top of mt everest exists?

ya it is, really

but i'm wondering why your logic is "something could be elaboratly faked therefore it is"

no it really isn't

the radio signal is there where orbit math predicts

and it sends down our radios messages that we programmed, so it's our radio

and it moves fast through the sky, and beacon's our identifyer

NORAD radar tracks all these objects too

you can see teh ISS yourself, it's bright enough

and with a telescope you can se others : https://www.youtube.com/watch?v=DNZV2e-fgPU

@jeremy but be careful of your logic, b/c this can be used against anything you believe as well, to be intelectually honest you have to apply it across the board, don't set up a double standard

@esports athlete all school shooters are white guys yes?

Yes of course

What do you think is faked about space recently?

and why

No i've seen the funny claims about it, but those are all easily explainable

i.e. how did they make the feather and hammer fall slowly , and at the same rate?

yes, that was a difficult shot ot get though

this is explained in books, i can recommend you some

that was difficult but ya they got it

that's just an assumption that its fake

then you're looking for reasons to confirm that assumption

what would've made it look more realistic?

well that's pretty arbitrary

Again how woudl they fake the hammer and feather footage

it fell at 1/6 g

@jeremy what about all the weghtlessness on the ISS footage
