> They just happen to be younger, or women, or of color. Maybe parent was referring to their mannerisms, rather than their appearance. It's not fair to jump to the assumption that parent was showing a bias against any of those variations in the human species.

To be pedantic, the poster did say "looks like" and: - "looks like" is associated with physical appearance - possibly things like clothes, jewelry, gender, hair, skin color, face, etc. - "sounds like" is associated with their speech - tone, accent, choice of diction - "acts like" is associated with physical behavior + speech But anyway, I think the point is that, we don't know what mabbo's intent was and 95% likely i…

> "looks like" is associated with physical appearance

Yes in very strict sense, but many people use "looks like", "sounds like" and so on interchangeably. I say "your proposal sounds good" even though proposal was sent by email and I didn't mean it is pleasing to my ears, melodic and soothing - I mean its content is OK. So we should not overanalyze and imply meaning that the author may not have put there. "Looks like" may just mean "gives general impression, by appearance, behavior, speech patterns, actions, etc." not necessarily excluding non-visual inputs. Human speech is not always precise.

That said, I agree that we should not have biases like if somebody, say, looks good on TV (and here again I don't mean just pretty face or nice clothes but more overall competent communicative behavior) they must be TV actor or hired comm person and can't possibly be genuine engineer. It's true that many engineers are awkward and some are socially inept, but that shouldn't be required. One can be a good engineer and a good presenter and a good communicator.

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

I get a headache watching Star Wars like sci-fi where everything is manually controlled by the pilot. How did sci-fi get so disconnected from the actual future?

>How did sci-fi get so disconnected from the actual future?

The original Star Wars was made in 1977, and based heavily on World War 2 combat films (much of the space combat and the trench run on the Death Star was lifted - sometimes shot for shot - from a film called "The Dam Busters.") For reasons of continuity and tone, that mechanical aesthetic can't ever change much throughout the franchise, or else it wouldn't "look" like Star Wars.

But the point is that it's exciting, it's visceral, the archetypes of the fighter pilot and joystick and of buttons that do important things make sense to the audience, and as a result those scenes can convey emotion though the use of familiar visual language.

Sci-fi was never "connected" to the future, and it was never (or at least, never explicitly) about attempting to accurately describe or predict the future. Yes, you could have replaced the ships and pilots in Star Wars with remote or AI controlled drones, not colored in the blasters, etc, and it might be more realistic, but no one would enjoy watching it.

People do enjoy dogfights (and spaceships that bank when they turn) and space wizards with laser swords doing flippy shit and punching each other with telekinesis, though.

"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...

Was it just lucky that the core didn’t directly impact the drone ship or was it designed to aim to the side in the event of the landing speed being too high?

It always comes in slightly to the side of the barge and as part of the landing burn it does a final sideways correction. I believe it was for this kind of situation - or one where the final burn doesn't even happen.

Falcon Heavy is 1/10th the cost of other heavy lift launchers, and able to launch 10x (or more) often, with a higher payload. This is no baby step.

Yes, that's important. Wonder what success of FH would do to works on BFR? If BFR would be as successful as Musk writes, would SpaceX make two rockets - or optimization will lead to just one?

FH success mostly helps BFR in regards to operating a ton of engines simultaneously (27 for Heavy, 31 for BFR) and in operating heavy lift capacity rockets in general.

BFR/BFS will come online as a self-competitive offering from SpaceX initially and both lines will be out in the market together (BFR vs. F9/FH). If and when BFR attains sufficient maturity, reliability, and market trust then the Falcon line of rockets will be phased out. BFR will have much greater capabilities (higher payloads, etc.) but will be substantially cheaper because it'll be 100% reusable and the reusability longevity for its parts will be much higher than for F9/FH, so there won't really be much reason to keep Falcon 9 or Falcon Heavy around.

This is why I love the live streams hosted by John Innsprucker. He doesn't look like a TV star, he looks like an engineer, a rocket scientist. He looks real. The other hosts are great, but if you told me they were hired actors or PR people I'd believe it.

You're showing your biases here. The other people on the livestream are also rocket scientists. They aren't PR people. They just happen to be younger, or women, or of color. So you might want to re-evaluate what you think a rocket scientist "looks like", because your notion is outdated. Sorry to call you out like this, but these kinds of prejudices about who is the "correct" kind of person for tech jobs are harmful a…

It's a bit aggressive to assume OP's metrics of what "looks like" a rocket science includes being an old white male.

Actually, you're the one who introduced these features as being relevant, and thus the only one perpetuating these features as being stereotypes right now is you.

Is it okay to put unnecessary stuff in the orbits around our or other planets? Isn't this space trash that can potentially be problematic for future endeavors? Are we creating problems for ourselves to satisfy our vanity?

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.

Good comment. All the people trying to derail the conversation by claiming you are derailing the conversation could have just upvoted you instead or commented "good point" and then upvoted that.

I really did not want to derail the conversation into this topic anyway. I'm a lifelong space fan and I've been looking forward to this launch for years. I watched it live today with dozens of my coworkers. But I went to read the comments here and the second highest comment wasn't about the magnitude of the achievement or anything like that, it was just a throw-away comment about the way the livestream's hosts look.…

I really appreciate that you called me out for it. I wasn't being clear in my meaning, and I totally see your point. Too late for an edit now unfortunately.

It's such a shame that so many people with Elon kind of money aren't doing anything to transform us into a spacefaring species. Why doesn't apple have a mars program? What the fuck are people doing with all the money? Awesome work by spacex. They are peerless, except if you want to count massive superpower governments as peers.

Because they're too busy trying to save millions of people in third-world countries to care about first-world problems.

Less snarkily, the pitch of Elon Musk is surprisingly selfish--he's basically doing this as much so he can get to Mars as anyone can. By contrast, people like Rockefeller and Carnegie in the past are largely responsible for endowing public culture in the form of museums, concert halls, public libraries and the like, and the modern day equivalents like Gates and Buffett are attempting to eradicate malaria from the world.

Nevertheless, you should reserve ire for those who have the ability to do philanthropy and fail to engage in it in any form as opposed to those whose philanthropy isn't in the areas you'd prefer.
