As of about 10 minutes ago Elon Musk has heavy lift to orbit capabilities. He's that much closer to being a Bond villain. There's also a Tesla Roadster on it's way to mars orbit (not mars, but it'll pas through Mar's elliptic).
The coolest thing to watch was the simultaneous dual landing back at Canaveral of the boosters.
SpaceX had a pretty good day.
-
Just put Elon Musk's Tesla into Orbit. (And I believe I read it was headed to Mars. I didn't actually listen to the launch, I just watched it.)
http://www.spacex.com/webcast
Wow. https://www.youtube.com/watch?v=wbSwFU6tY1c
Landed both boosters simultaneously, as well. (Not sure what happened to the Core, as the cameras got obscured and, they didn't report before the feed was ended.)
Wow. again.
-
Yeah, that was really cool.
-
Dupe topics merged, nerds.
=D
(It IS cool stuff)
-
Wow, way to stick the landing.
-
For those who want the highlights, on the youtube video:
Actual launch right at 30:00
Booster separation at 32:30
Main engine cutoff at 33:00
Simultaneous landing of boosters at 38:00
Core landing getting obscured at 38:30
(All the times are approximate. Click a few seconds before and you'll be fine.)

They do seem to have misplaced one of the boosters however.

Huh? They both landed at the same time on adjacent pads.

There were three booster cores. The third was supposed to land on a barge in the Atlantic. Cameras cut out right before touchdown, and SpaceX isn't saying what happened.

Oops.

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.

Given that the goal going in was "not explode with the force of a tactical nuclear device (http://markets.businessinsider.com/news/stocks/spacexs-falcon-heavy-could-explode-with-the-force-of-a-nuclear-weapon-2018-2-1015006848) while sitting on the launch pad" I'd say they still did pretty well... =)

2 outa 3 ain't bad.

Now don't be sad.
Actually watching the video of lift off was just as cool as when I watched the original Columbia mission.
-
I thought it was a joke when I heard someone mention a Tesla car in orbit. Apparently not. Pretty cool.
-
Not so much in orbit as in trajectory.

I made that same connection on another forum last night. I wonder if Musk also made the connection.
I grew up listening to the soundtrack to Heavy Metal at my grandmother's house. My aunt apparently bought a copy on vinyl and left it there for whatever reason. I nearly wore it out playing it on the old console stereo. :D

One of the comments on the video said it must be fake, because obviously the tires would explode in space, right? Then somebody replied that, duh, it's not some regular car - it's made for a space environment, dummy. :laugh:
-
Bringing a tire to outer space, with no external pressure on it any more, just brings the effective pressure in the tire up by 14.7 psi.
-
Leave out the valve stem. Same PSI in as out and the tire will hold it's shape due to the structural rigidity of the tread and sidewalls.

That was among the 4 or 5 low-tech solutions that immediately suggested themselves to me. If it was a problem to begin with. But no, the people that successfully launched a massive rocket, and brought about the simultaneous landing of two rocket boosters could never be as smart as us, right? ;)

Salon being Salon again:
https://twitchy.com/brettt-3136/2018/02/13/salon-elon-musks-launching-of-a-tesla-was-a-slap-in-the-face-to-real-science/
Because everyone wants to spend a year and $$$ to develop a science suite (plus setup the infrastructure to monitor the sensors for the next "X" years) to stick on top of the first launch of an experimental booster. Salon evidently never watched The Right Stuff (probably because it was the patriarchy).
-
"Real science"? Was Musk claiming to do science, or was he doing technology? I honestly don't know what his pretensions were.
-
Salon should probably at least google things before typing.
Test launches of new rocket designs NEVER have real payloads. Because test launches of new rocket designs blow up a lot, and who wants to blow up their fancy satellite/test instruments or whatever? IIRC the Falcon test launch had a huge wheel of cheese.
The real gripe there is they don't like Musk, so nothing he does is allowed to be OK.

At one point there was a really good Aardman Studios documentary on Netflix. No idea if it's still available.

The tires would not explode unless they were over-inflated to begin with. (pretty sure the correct inflation for space would be about 15 psi less than on Earth)

In other words -- roughly zero psi. (Atmospheric pressure at sea level is approximately 14.7 psi)
-

No, it would be normal tire pressure (30 psid) reduced by 15 psid before launch so that the final pressure once in space would be back to 30 psid.

Y'know, if I had Musk's bank balance, I'd have very secretly put some serious animatronics in that suit, on a long delay timer. Wait until the people who were watching it live from launch got bored, then have it wash the windshield, lean the seat back, scratch, etc. Start the rumor that this is the most epic assisted suicide in history.

Wonder how many "dead hookers" would fit in the trunk?

Okay, that would actually be pretty hilarious. :laugh:

10-4
Although the manufacturer's recommended tire pressure for a vehicle weight of essentially zero probably wouldn't be 30 psi.

Why not just leave the tires empty, poke tiny holes in them so the pressure equalizes as the rocket gains altitude, and in the vacuum of space the natural form of the tire will hold it. Or, if it's a flat tire, atleast it's flat on all sides simultaneously. [popcorn] >:D >:D :rofl:

Well, yeah. If you were worried about it, you could drill holes in the inboard side of the tires. You could break the seal between the tires and rims. You could take out the valves. You could replace the tires with solid rubber, or plastic. And on and on...
-
Simplest route, remove the valve stem core.

and airbags!

Right now some SpaceX engineer is slapping his forehead over the revelation that an unknown internet forum nobody has pointed out something he and his colleagues failed to understand and act upon. :facepalm: :rofl:

Amazing how these things get started.
Obviously, if you pull the valve cores or otherwise create leak paths, when the tires got up in space, they'd collapse because they'd be full of vacuum.

No, not scientific enough. We must do the maths first and get the right pressure! =D

And don't forget to account for the rubber stiffness from the cold....
REF for playtime:
https://www.mide.com/pages/air-pressure-at-altitude-calculator
At 40 kilofeet, ambient pressure is ~2.3 psia, figuring 15°F. Was curious about that on them aerioplanes up there and their tires and like that there stuff. Fifteen°F was just a plucked out of thin air number. (Pun intended.)

Nice little calculator, but doesn't go high enough. Max is 65,000 feet. At 65,000 feet and -40 degrees (it's probably a lot colder in space) the air pressure is 0.33 psi.

Yeah, and it's persnickety about the units if you don't set it up right. But 0.02 Bar (0.33 psia) is a pretty good "vacuum," or more correctly, a pretty low pressure.

Actually, under the launch acceleration they probably do flatten out considerably.

The Martian had a budget of 108 million.
A Falcon Heavy launch with no cargo 90 million.
Not sure you could make a human carrying spaceship that could do life support for a mars trip with 18 million. If it takes a second launch to loft fuel and consumables then definitely not.
