During the London Space Week SUA will give a presentation called "60's High Tech". The presentation will be about the development of control algorithms in the current digital age compared to the analog controller of the first lunar lander. A lot has changed in the development of control systems compared to 50 years ago when the first lunar lander spacecrafts were build. The current digital age enables engineers to implement the "perfect" guidance and navigation system. I would like to point out however the elegance with which the engineers at the Hughes Aircraft company build the spacecraft with limited components available. There are lessens to be learned for all disciplines in this story: it is not about the number of options you have available, it is about the effect of your implementation.
