Falcon 9 is painted white to avoid heating the liquid oxygen.
Why is Electron not also painted white?
Rocket color-related questions:
- Why parts of RocketLab's Electron become white before launch?
- To what extent, if any, does the exterior paint color of a launch vehicle affect its propellant & vehicle thermal management?
- Is the mass of paint relevant in rocket design?
- Could a shiny metallic fairing have some engineering advantage? Disadvantage?
