0:00.0 | If we could get to the moon in the 1960s, why does it seem so hard to do it now in the 21st century? |
0:15.7 | Like we've all seen, or remember, the 1960s, we had giant computers that could now fit inside of a little calculator, |
0:24.9 | let alone the computing capacity of your smartphone. We had technology that is laughably out of |
0:31.8 | date by today's standards, and we just did it. And yet now it seems almost impossible. |
0:39.9 | Like we've been trying to recapitulate it for almost two decades now. |
0:44.3 | Like we've been hearing for decades, we're going back to the moon, NASA's back to, |
0:47.7 | we're headed back to the moon, more people on the moon. |
0:50.6 | It's taking forever. |
0:53.4 | Our current plans are bloated, horribly late, over budget, and it seems like it's getting worse. |
1:02.0 | What's going on? |
1:04.1 | Well, to set things up, let me paint the picture of the difference between the 1960s and 70s, |

1:17.8 | On July 16, 1969, we made history. |
1:21.2 | At 9.30 in the morning, the Saturn 5 rocket, |
1:23.9 | the largest, most powerful rocket ever built, |
1:28.4 | ignited. |
1:35.7 | Capable of over 34.5 million newtons of thrust at launch, the Saturn 5 hoisted 48 tons of fuel, equipment, landers, life support, systems, communications, gear, a command |
1:41.9 | module, a descent module, and an assent module, and three |
1:45.4 | human beings into space. It was a three-stage rocket with the first two stages igniting, |
1:51.0 | burning, and detaching, before lofting the remaining spacecraft into a stable parking orbit |
1:56.9 | around the earth. After a couple orbits, the third stage ignited its own smaller rockets, boosting the spacecraft |
