On a more positive #tech note!
Spacecraft attempts closest-ever approach to Sun 🚀 ☀️
This is the Parker Solar Probe, and this is a special one! Since it will be the fastest hooman-made object ever
It will reach a speed of ~200 km/s or 720 000 km per hour!
I am also so amazed by the temperature difference the thing has to endure
It will fly though the corona of the sun that's about 1 million °C! 🥵
It has an amazing heat shield that will protect the instruments on the back to a nice room temperature, how crazy is that!
🇳🇱
@stux You are forgetting this is space... high temperature yes, but very very low heat. Once the IR itself is blocked by the shield the low pressure means that while the gas in the area is very hot there is very little of it, so it doesnt actually heat anything up.
You cant think of it as sitting in an oven at that temperature. Its actually a low-heat environment.
@stux Absolutely, I mean its impressive engineering in its own right. Just pointing out that a low-heat high-temperature environment is quite unique and the heat is quite manageable once you block the IR.
@freemo Oh sure but still! 😉 it's nothing compared to the LHC for example but it's an a pretty hostile env already in space
