 This is Margaret Hamilton, head of the team that developed the onboard flight software that landed us on the moon. She coined the term software engineering, got a special prize from NASA, got a presidential medal of freedom. 50 years after the moon landing, what if she got a thank you? From the moon. This is the Ivan Paul solar facility. Hundreds of thousands of car-sized mirrors reflecting the sun to create energy. What do they do at night? What if we thought of them as pixels? Hundreds of thousands of pixels, individually positioned to reflect the moon. Forming an image visible from the sky. A 1.4 square mile canvas, bigger than Central Park, bigger than over 200 Eiffel Towers put together. Is that even possible? Calculate the trajectory of the moon. Find the perfect angle in Earth's studio. Record the aerial coordinates. Talk to these people in California that run Ivan Paul. Pat Costman and the operation scheme at Ivan Paul. Call the engineers in Israel that control the mirrors. We have Gil and Drotem and also Neta. Can we point those mirrors at the moon to create a giant image of Margaret Hamilton made of moonlight? Just one minute. We need to think about it. I can't give a positive answer yet. Contact Margaret Hamilton. Find a photo of Margaret. Make it into a tribute. Make it into pixels. Translate that for 107,555 mirrors. Only one more full moon before the anniversary of the moon landing. We need to talk to Margaret. Hi Margaret. Hi. Next week we're going to be going out and create a giant portrait of you on this entire field. That's a lot to do between now and then. Go to Ivan Paul. Hi, we're here from Google. We've just arrived. It's our first time seeing the towers all lit up. Which is pretty amazing. Watch a safety video. Put on snake boots. Watch out for wildlife. Meet a tortoise. Hi tortoise. Call Israel. More math. Wait for sun down. Position the mirrors. Track the moon. Take to the sky. 430 is going to be the cutoff. Not high enough. 40 miles per hour wins. Lose communication. Adjust coordinates. Moon set. Time's up. Not tonight. Even if we miss the target in one degree, you will not see anything. Recalculate sunrise and breakfast. One last chance. Moon rise. 99.3% illuminated. Steady. Climbing. Searching. Find it. One point in the sky. There's Ivan Paul. There's the moon. There's Margaret Hamilton. I think that was the best. It was gorgeous, man. Amazing. Take a picture. Margaret by moonlight. This is Margaret by moonlight. And I noticed how that co-
