"That core booster approached the platform as planned, but it unfortunately hit the water going 300 MPH and was lost, because some of its return engines failed to light" https://techcrunch.com/2018/02/06/spacex-landed-two-of-its-t...

I'm kind of glad they had something fail. That means maybe they learned something new to improve the next shot.

most of the people I know are twisted pessimists. you're a twisted optimist

It's not quite our generation's "one small step for Man" moment (I'm saving that for when we actually land a human on Mars) but it's damn close.

I hope it's not close to our generational moonshot. We've had quite a few impressive launchers in the past - not commercial, of course, but also built without current level of accumulated experience - so to consider FH their modern version would be to accept lowering the standards. Nevertheless :) FH first launch is an impressive feat.

If they keep going the way they're going, I think our generation's moonshot is going to be a Mars-shot.

There was something doubly awesome about the two falcons landing at the same time right next to each other!

Can confirm this was the greatest thing I've ever witnessed in my life. https://youtu.be/AGPH_i0ZlyM?t=56

Ya, was stunning.. https://twitter.com/SpaceX/status/961084879432597504

Mars is really big relative to a car. You could probably put dozens or hundreds of cars in orbit around Mars without any added difficulty. Anyway I wouldn't normally consider it to be space trash, but in this case it's pretty much just a big Tesla ad billboard orbiting the planet so I agree with you sentiment

Space debris is a huge problem. One car gets hit bit tiny debris at any point, and the number of debris flying around multiplies.

Not where it’s going.

Space debris is a problem in a small number of high-traffic Earth orbits. There is almost nothing in existence on this random Hohmann transfer solar orbit where the car will live for hundreds of millions of years.

Space is big.

Did they need to modify the Tesla to make it vacuum worthy? Like, remove any fluids, remove any parts that might explode in the hot or cold of space, deflate the tires, etc. Note: I'm more interested in a scientific answer, as opposed to casual conjectures. Preferably from an engineer knowledgeable of such things. And specifically, the materials sciences aspect of how materials will survive in a vacuum.

Musk basically said "not really" in the press conference

On the other hand, there are indeed many scientists/engineers who look/act "nerdy" or don't have the suaveness of people we typically see on TV. I think what GP is saying is that typically companies will put forward people who are good-looking and charismatic for PR, so it's nice to see someone different and unpolished be center-stage in the public eye.

Why exactly is “good looking and charismatic” a bad thing? To be a good host you need to (should) be charismatic, that’s literally the job.

It's not a bad thing, but requiring it arguably is.

Most companies would require it.

What are you talking about. That gif is showing the fairing separation. There's no sphere.

amazing, is the car strapped to the outside of the rest of the ship? how does it remain so stable after the separation? by "sphere" i just meant the case it is shown inside of at the start, since the markings on the wall resemble motion tracking panels used for 3d projection. perhaps I just underestimate the precision and smoothness of the fairing separation, or am misunderstanding how the car is rigged so as to rema…

It seems SpaceX has even perfected its tests to the point that their simulations are doing an amazing job at predicting real life situations. Great job on spaceX. Today History was made, and the new generation of children is inspired to choose space-focused careers

Even the modeled exhaust in the rendering looked almost identical to reality. Top minds.

And there's still more! Live Webcam from Spaceman: https://www.youtube.com/watch?v=aBr2kKAHN6M

All of this insane expense and amazing science and they couldn't make a VR360 camera happen. :(
