Space Engineering

The practice of designing and building systems that operate in the most hostile environment imaginable, where temperatures fluctuate hundreds of degrees, radiation fries electronics, and a single micron of debris can end a mission. Space engineers must create machines that work perfectly after months of travel, with no chance of repair, using components that were tested on Earth but will never be touched again. It's engineering on hard mode, where failure is public, expensive, and permanent, and success means your creation dies alone in the void, doing its job until the end.
