Can we not? His achievements and things like his public fights with cave rescuers and the SEC are both public record and exhaustively discussed.

He who is without sin can cast the first stone.

No one's stoning anyone to death.

It is a mistake to believe the point of that parable is "you shouldn't ever even criticize anyone unless you're perfect".

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

> 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?

Putting humanity on a second planet is about creating a redundancy in case something happens to the earth.

That redundancy is designed to protect against rare events on that might well be 100,000 years away.

Going to mars to "save the human race" isn't a path anyone is proposing as an alternative to addressing climate change. That's a challenge we face across the next 10-200 years.

Going to mars to "save the human race" is about ensuring that, if a planet-scale disaster strikes the earth in 10,000 years the human experiment continues on.

They're two different challenges that we face, and I see no reason why we can't address both.

It did land, then exploded right now. There was a fire at the base of the SN10 and apparently got to the tank after a few minutes. 99% success. Next time for 100% hopefully.

I’ll need to go back and watch but I think the fire started on the way down and not at landing. Also, then engine shutdown looked “messy” on the landing burn. I wonder if the root issue was relight. I hope there isn’t a major flaw in raptor with respect to getting them to relight. Re-ignition had problems in every flight it is been tried (iirc).

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 item produced, 2 for each slightly less mediocre one, etc. with scores such that producing mediocre items at full speed at best gives them a low grade.

That gives the students both an incentive to start producing items soon (so that that can produce, as a safeguard, lots of mediocre items and get a decent grade) and to improve their technique (so that they can reach a higher grade, or finish earlier their work earlier)

Definitely looked like it landed a little hard and then looked like it was leaning a bit after.

Surviving extinction-level events like asteroid strikes likely requires an off-planet human civilization. But I do share your concerns about humans neglecting their ideal habitat, and think we need to be careful about mistaking efforts like colonizing Mars as some kind of panacea abdicating any responsibility to clean up our act at home.

Earth even if hit by an asteroid that killed dinosaurs, Chicxulub impactor, would be more habitable than Mars.

But if we manage to establish self sustaining city on Mars we will be sure that we can survive everything on Earth.

Also, having a working blue print of what to do in the event of a sudden disaster on that scale would certainly be helpful.

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.

I'm sorry, a giant asteroid just hit the Earth and wiped out all life on the planet rendering your questions meaningless.

Earth is a single point of failure.
