When President Kennedy said, “Let’s go to the Moon,” it wasn’t just science fiction, it was impossible. Less than 100 months later, Neil Armstrong and Buzz Aldrin were bouncing around in blazing white space suits at Tranquility Base. It took an army of 410,000 Americans to get them there, along with MIT and Playtex. The real impact, of course, was back on Earth — the race to the Moon changed how we live, then and now. It also has invaluable lessons for how to tackle the biggest problems we face today.
