It helps that car engines don't really _need_ sensors to function. Cars existed before electronic sensors. A mars lander actually needs to know when to deploy parachutes.
- WalterBright 10y agoIf the lander cannot function without an altimeter, and there is only one altimeter with no backup plan, then you can plan to lose the lander. This is not a new idea. Airplanes cannot fly without instruments, and all the instruments have backups and alternate means. Everything deemed "flight critical" has a backup alternative.
