It has been 50 years since the first human landing on the moon. This week, people commemorate the “Apollo 11” rdquo; How can such a big event get the participation of Google?

Not only is the home doodle commemorative, but Google’s engineers have also born a bold idea:10. 70,000 mirrorsReflecting the moonlight, forming a hugeMargaretThe Apollo plans to be the head of a famous female programmer. Total area approximately3. 6 square kilometers, enough to accommodate 200 Eiffel Towers.

Yes, you are not mistaken, not reflecting sunlight, but moonlight. Location at the Ivanpah Solar Power Station in the Mojave Desert, California.

During the day, the mirrors are used to reflect sunlight, and they are focused on the boiler in the center of the power plant to generate electricity using the generated high temperatures. At 8:07 pm, the engineers used the mirror to track the moonlight and put out the Margaret head, as well as her name and the words of Apollo 11.

About Margaret

In the Apollo mission to the moon, Margaret Hamilton led the team to develop airborne flight software. It was because of the robustness of her software that Apollo 11 was able to ensure that the spacecraft successfully landed on the moon.

There is a little story in the process of studying the moon landing code.

Margaret had a daughter at the time, and she came to work with her daughter Lauren. Margaret often tests the program in the simulator, and one day Lauren pressed a button that crashed into the spacecraft in the simulator.

But Margaret did not scold her daughter, but instead had an idea: “What if the astronauts do the same thing in real missions?” & rdquo; So Margaret proposed to increase the code to prevent the system from crashing.

Three minutes before Apollo 11 landed, the computer was overwhelmed and a series of reboots triggered an alert that could have caused the suspension.

But the software written by the Margaret team is robust, the entire system is still working, and the alarms are prioritized for the astronauts to make a decision. In the end, Armstrong can take that "small step".
