Do you really know Margaret Hamilton? For aeronautical achievement and engineeringς του προγράμματος Apollo 11 από τη γέννησή του, το 1961 μέχρι την ολοκλήρωσή του το 1972, χρειάστηκαν οι προσπάθειες αρκετών επιστημόνων. Η NASA και οι συνεργάτες της είχαν σκοπό να οδηγήσουν τους αστροναύτες έξω από την τροχιά της Γης με τον πύραυλο Saturn V, να μπουν σε τροχιά γύρω από το φεγγάρι, και στο τέλος να προσγειωθούν στο φεγγάρι.
The Apollo program was also a huge software project. The astronauts used a computer to navigate and control the spacecraft to guide the Apollo. Someone had to program this software…
The software for the computer was written by a team at the MIT Instrumentation Laboratory (now called Draper Laboratory) headed by Margaret Hamilton. Below is an amazing photo that shows it next to the code written by her and her colleagues for the guidance of Apollo 11
“Σε αυτή την εικόνα, στέκομαι δίπλα στο source code του Apollo Guidance Computer (AGC),” αναφέρει η Hamilton στο Vox σε ένα message electronics post officeU.
The process of genuinely encoding programs has been painful. The computer used for guidance was known as "Core rope memory" wires tied through the metal cores in a certain way to store code in binary.
"If the wire went through the core, that represented one." reports Hamilton. "Around the core represents zero."
These programs were hand-knitted at the manufacturing plant. And because the factory workers were mostly women, the basic core rope memory was referred to by engineers as "LOL memory," which LOL comes from "little old lady."

The Margaret Hamilton's code was so good that it had forecasted everything, but the overload of the computer threatened the mission as it had no room for the computational work required for landing.
But that was predicted by Hamilton.
The computer was also programmed to restart automatically and almost instantly. That way he could clean up trivial tasks like radar data, ”says author David Mindell. Digital Apollo: Human and Machine in Spaceflight
"If the software did not work, the lunar eclipse would not have happened," he said AJS Rayl .
Margaret Hamilton is currently 78 and has the Hamilton Technologies, Inc. a company in Cambridge that founded 1986.
