AI Thread Summary
Highly sensitive space accelerometers do not typically require heat shielding for operation in the thermosphere, as they are designed to function within extreme temperature ranges. Instead, these accelerometers are usually mounted on isothermal panels inside spacecraft to maintain a stable temperature. Their components are engineered to ensure accuracy despite temperature fluctuations. The primary shielding for these devices focuses on radiation protection rather than thermal shielding. Understanding these design features is crucial for ensuring the reliability of accelerometers in space environments.

Can someone please explain to me if highly sensitive space accelerometers need to be heat shielded before use in the thermosphere, if they already are heated shielded, or if their components are designed to work in those conditions?

If they don't need heat shielding can you explain how their components are still accurate in that extreme of a temperature range?

Thank you.

Typically, electronics are mounted on the inside of the spacecraft to an actively controlled isothermal panel to maintain temperatures inside a 'comfortable' range.

They're typically only shielded against radiation, not heat.
 

Thread 'Never think never for an improbable event'

Pilot training is critical to safe flying. I watched the following video regarding the crash of TAM 402 (31 October 1996), which crashed into a Sao Paolo neighorbood about 25 seconds after takeoff. https://en.wikipedia.org/wiki/TAM_Transportes_A%C3%A9reos_Regionais_Flight_402 The pilots were never trained to handle such an event (the airline had asked the manufacturer about training for this event), since it was considered too improbable (so rare) by the manufacturer. There was no...

Thread 'Space Stuff and Launch Info'

Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile: https://blogs.nasa.gov/spacex/
