MLI consists of lightweight reflective films assembled into thin layers that range in thickness. These layers are usually made of polyimide or polyester films (types of plastics) coated with very thin layers of aluminum. The exact composition depends on where the satellite will orbit, what the insulation will be protecting and how much sunlight it will be exposed to.

The gold and silver colored sheets you see are often a single layer of aluminized polyimide with the silver aluminum side facing in. The yellowish-gold color of the polyimide on the outside gives the satellite the appearance of being wrapped in gold.

see there is a basic engineeering standards

Multi-layer insulation is used on satellites primarily for thermal control and protects the delicate on-board instruments from the extreme temperatures of space. Depending on its orbit, a satellite can experience temperatures from below -200°F to well above 300°F, sometimes at the same time! Not to mention the high temperatures the onboard instruments can produce.

While MLI does not insulate a spacecraft from heat conduction or convection very well, this doesn’t particularly matter in the near-vacuum of space. With no air around, radiation is the dominate form of heat transfer. MLI is designed to reflect solar radiation back into space, keeping the instruments cool enough to operate while in sunlight. It also maintains internal temperatures by keeping heat in, protecting the instruments from the extreme cold experienced when the spacecraft moves through Earth’s (or its own) shadow.

MLI can also provide a layer of defense against dust impacts, protecting delicate internal instruments and sensors from tiny particles of space debris.
Although sheets of gold are not used to cover entire satellite bodies, real gold is in fact used on some satellite components. From vapor-deposited gold taping to gold coating, gold is used because of its multiple benefits in outer space. Gold helps protect against corrosion from ultraviolet light and x-rays and acts as a reliable and long lasting electrical contact in onboard electronics.

Gold is also used by NASA in the construction of spacesuits. Because of its excellent ability to reflect infrared light while letting in visible light, astronauts’ visors have a thin layer of gold on them to protect their eyes from unfiltered sunlight.

and one of em is called points of failure

and other thing slike metal fatigue

Space foil

radation

electro static etc

these rules cant magically disapear to beat the russians

im sorry

true

its also only -40 on mars

it has alot more temp

the moon is -170

Wait do you think that sun produces radition like a nuclear reactor

because it dosnt

aries what is the temp of the moon

record in sunlight during the missions

recorded nasa gospol

do you know

Radiation on earth spreads alot differently than in space

im muting you if you dont

no thats cold

whats the hot

Yea it cold

do you know

Do i know the temperater of the moon or the sun

?>

!mute @Aries

Aries#2635 (563552975583313930) is now muted for '**Unspecified.**', alright? <:THUMBSUP6:403560443345371137>

450 F

welp

the answer is 400+F

would been sufficent

dont profess to be a space wiz

if you cant know basic facts

yup

remember they had to run to ht e lander

cause of nights -170c

and thats why no nighttime

i cant stand nasa trolls who dont even know basic science
