The thing that impresses me even more is the kinds of cameras they mount on the rocket. How do they shield it from all the heat and debris with a material that's optically clear?
- ceejayoz 2y agoThey put it in places the heat and debris don’t go.
- jjk166 2y agoSapphire glass windows: they're good for up to 2000 C, mechanically strong and chemically resistant, and remarkably cheap.
- ars 2y agoSapphire is Aluminum Oxide. Transparent Aluminum basically. It's an amazing material that is not used as much as it should be.
- daxlemons 2y agoSapphire windows are good, yes. Want to minimize delta_T across window body (and therefor stress), other materials are better for that. Cameras are sealed to the skin to prevent against any crossflow and enclosures tend to have various thermal insulations (e.g., ablatives).
