Half a century ago, astronauts got on top of a really big rocket and sent a tiny little capsule on a 384,000 km trip to the moon and back. And they were able to do it because a lot of extremely smart and dedicated people pushed engineering and chemistry to the limits in order to create a 36-story tower of carefully-controlled space fire powerful enough to escape Earth’s gravity. I went to NASA in Houston to talk to astronaut Don Pettit about how they did it, and if we’ll be able to do it again.

Launching big tubes of space fire is hard. I’m grateful to my favorite astronaut Don Pettit for explaining the physics of the rocket equation to me in simple terms that my biologist brain could handle 🤓
-
"I was told there would be no math" Well, this is literally rocket science...
-
That comment just struck me: "it takes three to five days to get to the moon." Just nonchalant 3-5 days. Imagine telling that to Columbus.
-
That one missing tail section on that dinosaur model is gonna bug me all day.
-
"The sky is not the limit!" I like that.
-
As a Texan, I love how you're clearly at a Buc-ee's when filling up your car.
-
Get yourself a partner that looks at you the way Joe looks at Don.

Kids, the sky is not the limit . . But Gravity Is Paraphrased from Joe Hansen
-
I can't handle the amount of freakin mIND-BLOWING INFORMATION IN THIS VIDEO !!!!! JOE, HECK
-
“We’re already pretty good at engineering planes” meanwhile at Boeing ...
-
"We've been to space! I can't even believe we have to do this!" I can't stop laughing...because science! I want a D.A.F.E. shirt. LOL 🤣🤣🤣🤣 (Edited for misquote)

The bit starting at 0:38 was not entirely accurate. Joe points only to the CM (Command Module), but the CM, the SM (Service Module), and the LM (Lunar Module) all went to the moon. The CM and SM came back to earth (as did the LM ascent module for Apollo XIII). The SMs for every Apollo mission all returned to earth and burned up during re-entry. The graphic at 3:48 shows all these parts as part of the "1%", though.

I’m so Texan I could tell he was at a Bucee’s just from that clip

To deeper your rocket knowledge, you can go to Everyday Astronaut and Scott Manley's channel.

I love how Joe told us to not get scared by a mathematical equation. I wish my physics teacher can do that too.
-
You heard it here first, folks. The 1% depends entirely on the work of the 99% to get anywhere.

"I was told there would be no math." -me entering Psychology
-
Can't we just sacrifice some Kerbals and wing it?
-
I think everyone keeps forgetting that this needs an industrial scale energy and resource infrastructure built on the freaking moon...

My first thought after watching this was: If the Earth was 10%-15% larger we couldn't have a space program, does that mean if the Moon wasn't knocked off of Earth by that meteor we would be too large for space travel? I suppose even if we weren't too large not having a moon would cause loads of other issues, but that was my first thought.
