Limitations

The accuracy of your modelling is limited by the quality of the data you use and the assumptions you make.

Reliability & validity

The reliability of the modelling depends on the consistency of the simulation parameters and the validity of the models in representing real-world Martian conditions. The selection process aimed for validity by incorporating multiple data sources and expert review.

Think critically

To what extent can modelling fully account for unforeseen environmental variables in a high-risk design project, and what are the implications for risk management?

Design Principles

"In high-stakes design, integrate predictive modelling of both performance and safety to achieve optimal site or operational environment selection."

This case demonstrates how complex design projects, especially those involving high-risk environments, necessitate a robust modelling strategy that accounts for both performance goals and operational constraints. Such an approach allows for informed decision-making and risk mitigation.

What This Means for Your Design

When designing something that needs to work in a specific place, like a robot on Mars, scientists and engineers use computer models to figure out the best spot to land. They look at where the most interesting science can be done, but also make sure the ground is flat enough and safe for landing.
