He's trying to make humanity a multiplanetary species while at the same time trying to get humanity off of fossil fuels by completely upending and dominating: 1) The space industry 2) The automotive industry 3) The solar industry 4) Some parts of the world's power grid infrastructure. He asks a LOT of his employees, and despite his companies being 15 years old at this point, asks for the type of commitment from emplo…

While I believe he truly wants to make humanity a multi planetary species, I doubt that's out of the goodness of his heart. You can do this without being a shitty person. Or overworking your employees. This is a long term project.

On what basis do you doubt that? Nearly everything he does or says, every interview, every company, seems singularly focused on the goal of bettering the chance of humanity existing forever.

What insight do you have that I’m missing?

I wasn’t watching a very high res stream but did anyone else notice what looked like a blackish/sooty exhaust on the way up from one engine? Maybe it was just the video feed... My hunch is at least one engine wasn’t performing 100% but the flight control software was able to compensate pretty freaking well.

I agree. On the SpaceX stream from inside the engine shroud it was very clear that one engine had a blue flame-exhaust, while the other was noticeably yellow.

My laymen rocket skills makes me think the yellow one wasn't performing very well.

Reminds me of this story: The ceramics teacher announced on opening day that he was dividing the class into two groups. All those on the left side of the studio, he said, would be graded solely on the quantity of work they produced, all those on the right solely on its quality. His procedure was simple: on the final day of class he would bring in his bathroom scales and weigh the work of the “quantity” group: fifty p…

“It seems that while the “quantity” group was busily churning out piles of work – and learning from their mistakes” Why would they care about quality? If they learned from their mistakes, they would make two or three pots, each one heavier than the rest (smart students would just make one item, making sure it weighed at least 50 kgs). This probably would work if the teacher promised them 1 point for each mediocre ite…

Perhaps they're taking a pottery class because they are actually interested in producing good pottery and are intrinsically motivated to improve the quality of their work rather than just gradehacking.

A novel and naive idea in the twenty-first century, but a man can dream.

Can you share a link to the explosion? The Twitter video cut out with rocket intact.

It's in the stream here, higher res than the twitter video posted below. https://www.youtube.com/watch?v=XOQkk3ojNfM

I don't think we can link specific times in a stream that is still going, so if you go to that link, rewind to T+14:30 shown in the top left corner

NASA would have spent 2 trillion and 50 years to get to this stage. SpaceX's rapid iterations and fail fast methodology might save the human species

Of course, this wouldn't work for anything that actually requires a large portion of a semester to achieve good quality.

Two of the three engines flaming out in the last few seconds, was that intentional? Something similar happened last time too, but at least this time it landed.

This wasn't done for SN8 and SN9, where they only lit one engine. Musk said that this time around, they were going to light all three and then shut two off, thus providing some engine redundancy during the landing.

I wonder about raptor re-ignition. They have it down with Merlin but it’s not torch ignited nor full flow. I wonder how well that torch handles being in a lit combustion chamber and what the insides of the preburners are like after shutdown...

Ps so so easy to armchair quarterback. I don’t want to sound like I, even one tiny bit, am not constantly dumbfounded by SpaceX’s accomplishments!

Change my mind. Elon Musk is the greatest man alive today.

Why would I? The pain and sacrifice he went through to get where he is right now is just crazy....sacrificing the multimillionaire lifestyle is not easy.

I loved Lex's interview with Jason, he was talking about it as well.

We just wrote a piece this morning in Orbital Index about the iteration speeds of SLS, New Glenn, and Starship. SpaceX is putting everyone else to shame. https://orbitalindex.com/archive/2021-03-03-Issue-106/#heavy... Reminds me of this quote from NASA Administrator Charles Bolden in 2014: "Let's be very honest again. We don't have a commercially available heavy lift vehicle. Falcon 9 Heavy may someday come about.

I love the ¶ paragraph indicators - Google says it's called Pilcrow? [1] - at the beginning of each section. It's a great typographic choice. Reminds me of those legal documents where they obsess about formatting and labelling the sections. And by they I mean usually the junior/intern staff at the law firms who are stuck in the 80s with paper and faxes. [1] https://en.wikipedia.org/wiki/Pilcrow

Thanks! I love using less known typographic marks like pilcrows for stuff like permalinks, etc. hope you enjoy the newsletter :-)

> SpaceX's rapid iterations and fail fast methodology might save the human species Would you mind elaborating here? How will reaching a dead planet while we actively kill the literally perfect place for us to survive and foster save the human species, exactly? And how does a fail fast methodology fit in there?

Earth is a single point of failure.

By that line of thinking so is the Sun. So what? Earth is pretty robust its us monkeys that are the problem
