Design Principle

Holistic payload design requires the concurrent optimization of structural and thermal properties to ensure reliable performance in challenging operational environments.

How to Apply

When designing any system intended for operation in extreme environments (e.g., high altitude, space, deep sea), conduct a thorough analysis of potential structural stresses and thermal gradients, and design components and their integration to mitigate these factors.

Limitations

The findings are specific to the Sunrise mission's context and payload configuration, and may not be directly transferable to all types of scientific instruments or operational environments without adaptation.
