1-2: "Moon Machines: The Navigation Computer"

It is wonderful to know all the limitations that existed when we talk about programming that used to have so little space to be stored and that its memory was so small that programs that were robust enough will leaded the computer to a memory overflow.

In the case of the documentary, they talk a lot of these limitations that it was necessary to had in mind because if something (anything) went wrong, it will make fail the whole mission and condemning the astronauts to a certain dead. The project of getting the man to the moon was given to the MIT, when I saw that, I though "Omg, what kind of pressure the students and teachers had in that moment, because knowing that a simple error would be devastating".

One of the first problems that they found was that they needed an automatic navigation system that had the ability to orient automatically the spacecraft and allowing the astronauts to make the trip to the moon successfully. It was a whole new challenge to make that device because this device would need to have a perfect accuracy. At this point I was like "Nope, nope, nope".

I also found interesting the way the solve the memory problem and how they had been able to put a computer in a spacecraft (because in that time, one computer occupied a whole room). Actually, after seeing how they solved this I still thinking "Ammm... can you tell me how you did that one more time", I did not understand how it worked that module of memory.

Finally, it is important to know how the computer science was before and how thankful we need to be of all the new technologies that are being and will be develop in the future. It was a huge effort of the computer engineers of that time and its impressive how they achieved the goal of landing the first man on the moon.
