Title: Never mind the Tesla in space.
Post by: trdsf on February 10, 2018, 01:45:25 PM
Okay, 10 out of 10 for cool, 10 out of 10 for attention grabbing, but for my money, the mindblowing part of the Falcon Heavy launch was watching the two boosters come down and land upright.  Five years ago, I would've said it was all CGI.

I mean, that's 12 out of 10 for telling inertia and center of mass to shut the fuck up and sit the fuck down.

Holy Crap!  That was incredible.  I heard that happened, but to see it was stunning.  High speed projectiles screaming in at the base and slamming on the breaks just above ground to land spot on their pads.  It was like watching something in Star Trek.  I guess they won't be dumping the boosters in the ocean anymore.

Well, actually, the plan was to land the main booster on a remote-controlled barge at sea—which they have done successfully before—but alas, that was a failed landing.  My understanding is that they cut their fuel tolerance too tight and it wasn't able to fully brake before touchdown.

So, dumping, no.  Landing...

Yeah, the core burned longer, so it was too far from Florida to touch down with the boosters. That would have been EPIC!

I am always in favor of good technology.  And I prefer it to not be tax payer subsidized, but I can understand NASA etc has to be.  I used to be a rocket scientist too (well at least as much as Elon) ...

I was involved with this kind of thing 1987-1989.

Agreed.  This and the Curiosity Mars probe landing successfully are probably this generation's moon landing.

I'm still holding out hope for a Mars landing during my lifetime!

He was looking for volunteers for the first flight.  Are you on the list?

Hell, I'd volunteer if I were healthy enough, but I'm not. I wouldn't even care if it were a one-way trip, hell, we've all got to go sometime, and I wouldn't mind dying on Mars, or even in transit. It wouldn't make a bit of difference once I'm dead anyway.

I would miss you ... unless your spaceship has a good Internet connection ;-)

I love Musk's quote: "I would like to die on Mars.  Just not on impact."

Lots of agencies and corporations are really gearing up for it.  Most optimistic picture (earliest plans come to fruition successfully) is about a decade.  A more realistic prediction would be two decades, maybe three.  But hey, I hear people are living longer, so there are baby boomers who might witness it.

I should be able to do twenty, thirty years.  The one I'd really love to see happen ASAP is Breakthrough Starshot; if they can get that outward bound in the next 10-15 years, I have a chance to live long enough for its arrival in the Proxima Centauri system.

Okay, extra coolness points for the Tesla in space: in the glovebox is a copy of The Hitchhiker's Guide to the Galaxy and a towel.  Also on board is a copy of Isaac Asimov's Foundation trilogy in a format that is projected to be long-term stable (https://medium.com/arch-mission-foundation/arch-mission-foundation-announces-our-payload-on-spacex-falcon-heavy-c4c9908d5dd1)—possibly (but not certainly) billions of years.  :D

What's this about blasting David Bowie's Space Oddity - while in space where no sound can be heard?

Actually, it was 'Life on Mars' and 'Starman' in rotation, as I recall.  Yeah, it couldn't actually be heard, it was just a style point.  I don't recall if there was an actual broadcast of those from the car or not.

I saw the image of the Tesla car in orbit, and 'Heavy Metal' came immediately to mind.  As I'm sure it did to Musk.

I sure hope that astronaut was strapped in good - he might go flying off and get lost in space.
