The part that really blows my mind is that Musk intends to (at some undisclosed point in the future) create a new transit system to "transport passengers between any two major cities in under an hour" using spaceflight - and that it'll cost little more than a good plane ticket. Wouldn't that be so amazing? I'm not even sure he can pull it off; it sounds like a sci-fi dream. I mean, it's technically possible, sure, but... I mean, I don't know, right? It sounds like science fiction. Could that even be cost-effective? Could it be safe?

The BFR [auto-censored] looks delightfully like a pulp sci-fi rocketship. It'll be too late for me, but I hope they deliver!
As for Earth to Earth: breakfast in London, elevenses in Sydney, lunch in LA, tea in Cape Town, and dinner in London.



I wasn't aware the forum had an auto-censor. I'll have to experiment - excellent fun! <sniggers>

I honestly thought of the same thing, Cody. :lol: I'm glad I wasn't alone in that.

I find it nigh impossible to take that Earth to Earth thing seriously. The cinematic is fun to watch though.

On the Earth-to-Earth thing, I haven't watched the video (not a big Musk fan), but I guess they're taking about ballistic trajectories?

I love those, too. I don't collect many things, but one of my prized pieces of stuff is a print of this, signed by Chesley Bonestell:

which I mention in part because it would make me unreasonably happy if Victor, that avid collector of cool things, thought this was worthwhile.

Very nice, Flat! :) And I share some skepticism about SpaceX's claims from time to time. But I can't deny that they're sometimes able to deliver some impressive feats. This is a bit much, though. I don't imagine it will be anywhere near as easy as they expect, especially because these rockets will bear so much similarity to ICBMs and headed directly toward major cities.

Yes, but... rocketships!

Since we are on the subject of missiles heading for major cities, here's a really nice photo:

Qualifies as a rocket launch!

To end the topic of missiles heading to major cities, the second Soyuz launch from Vostochny cosmodrome. Rocket itself worked just fine, but the final orbital insertion stage malfunctioned. According to some leaks, it's because somebody forgot to program the orbital insertion stage and sent it up with its old Baikonur-launched flight profile :ghost: I'll poke some people and try to find out whether that was the case.

Prepare to be unreasonably happy, Flat. That's a superb piece of print art. :thumbup:

Sorry for the delay in spotting your post. :angel:

Not a lunch exactly, but the first firing of Voyager 1's thrusters since 1980 - article at El Reg.

Read it elsewhere, really impressive how it can last so long and still function perfectly. A masterpiece of a probe.

In the meanwhile, another routine Soyuz launch to the ISS. Seems like it's one of the last launches in Soyuz-FG modification as its production will stop sometime next year, replaced with Souyz-2.1b.

Edit: also, because people oft accuse me of only caring about Russian stuff, here's some Falcon 9 but three times more explosive Falcon Heavy:

I also have a print of Kim Poor's "Attitude Hold" in my office. But I'll admit that owning a thing with the actual signature of Chesley Bonestell fills me with a sense of incredibly intense satisfaction. It's the most tenuous possible connection to the optimism of the Space Age, but it's a connection.

And I'll acknowledge here that this connection matters to me both intellectually and personally, because I got to watch Neil Armstrong step onto the face of the Moon as it happened. My mother, seven months pregnant with my youngest brother, was sewing in the other room and wouldn't get up to come see our black-and-white TV as I exclaimed in amazement at what was happening on July 20, 1969... but there was never any doubt in my mind that I was witness to a pivotal moment in human history as it happened, even if no one else cared.

If you think I must be disappointed that there was no sustained follow-up to this achievement -- no Moon bases, no exploration of Mars, no asteroid mining, no generation ships flung in hope toward the nearest stars -- you'd be right. My God, here it is, nearly 2020 -- 2020! -- and we're still just squatting here on Earth, arguing furiously with each other about how many genders there are instead of linking arms and working together to expand our personal human knowledge of the astonishing universe we share.

If my life, from The Lone Ranger to quantum teleportation, is a weird amalgam of optimism and pessimism, I hope I can be forgiven for it. To have so much possibility, and to feel so little desire to achieve great things with all these resources... it's hard to reconcile these.

I'd like to echo this sentiment of yours, Flat. :( With how far we've come in the past century, it's shocking to see people squabbling over silly, meaningless things instead of working together for a more beautiful goal. I hope at some point we as a species grow up and "act our age". :P

This is something I've thought about on several occasions and it never fails to sadden me. We ought to be working for the betterment of mankind, not getting caught up in our own insecurities, discomfort and greed.
