so when the cube sat is it -260 c the cubesat only gets -10 ?

2019-04-21 22:16:42 UTC  

scratch that

2019-04-21 22:16:59 UTC  

the cubesat is in a -260c degree environment but only gets -10c ?

2019-04-21 22:17:42 UTC  

it's never in that environment

2019-04-21 22:17:47 UTC  

in low earth orbit it's not that cold

2019-04-21 22:17:56 UTC  

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

2019-04-21 22:18:04 UTC  

like the pluto new horizons craft

2019-04-21 22:18:06 UTC  

we have been talking about the environment of the cubesat this whole time

2019-04-21 22:18:48 UTC  

i thought you were talking about space

2019-04-21 22:19:04 UTC  

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

2019-04-21 22:19:17 UTC  

so u say the cube sat temperate varies between -10 and plus 60c the actual temp of the cubesat?

2019-04-21 22:20:07 UTC  

yes that's right

2019-04-21 22:20:12 UTC  

still amazing

2019-04-21 22:20:14 UTC  

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

2019-04-21 22:20:19 UTC  

huge temperature swing

2019-04-21 22:20:24 UTC  

that's not much

2019-04-21 22:20:28 UTC  

your car engine ismuch worsse

2019-04-21 22:20:37 UTC  

and that's just an aluminum block

2019-04-21 22:21:05 UTC  

so before u shoot a cubesat up u test it in those temperatures?

2019-04-21 22:21:09 UTC  

yes!

2019-04-21 22:21:15 UTC  

we use a "thermal vacuum chamber"

2019-04-21 22:21:29 UTC  

and u get it that hot and cold

2019-04-21 22:21:33 UTC  

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

2019-04-21 22:21:41 UTC  

and an oven to make the higher temperature

2019-04-21 22:22:02 UTC  

guys should i bathe in gold to regain my sanity

2019-04-21 22:22:08 UTC  

ok so u make this cube sat and then give it to nasa ? spacex ?

2019-04-21 22:22:32 UTC  

well there are a lot of launch vehicles

2019-04-21 22:22:38 UTC  

should i bathe in that thicc gold

2019-04-21 22:22:40 UTC  

latest ones are from RocketLabs

2019-04-21 22:22:42 UTC  

its nice

2019-04-21 22:22:44 UTC  

but spacex does launch some

2019-04-21 22:22:50 UTC  

and luxurious

2019-04-21 22:22:54 UTC  

who do u personally hand ur cubesat too

2019-04-21 22:23:01 UTC  

aint spacex gonna go for mars in the mid 2020s

2019-04-21 22:23:31 UTC  

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

2019-04-21 22:24:38 UTC  

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

2019-04-21 22:24:40 UTC  

no profit

2019-04-21 22:24:50 UTC  

ok so u hand ur cube sat to a launch provider then u watch it take off

2019-04-21 22:24:54 UTC  

yep

2019-04-21 22:25:07 UTC  

and then u get data back that is impossible to fake ?

2019-04-21 22:25:32 UTC  

yes
