Can someone point me to information about the Roadster and it's payload? I'm trying to look it up in order to make a Stellaris mod, and I simply can't find some of the information.

Namely, I'm curious as to-

What the overall mass was (is there a big block of cement in there somewhere?)

Where in the car is the Ark 5D disk?

Is the paint a polymer, or something with a lower chemical weight more likely to hold up when exposed to solar wind?

In the press conference today someone asked Elon about the Tesla. He said it's just a Tesla. Just a normal car, factory seats, normal paint job, nothing special.

16 story!

First stage (booster) dimensions that I find online give the height of that segment as 40-41 metres (including engines), depending on configuration. That works out to about 12 stories tall for the bit that comes back down, so I guess we're both wrong...

Musk said 16 stories today, IIRC, in the press conference. I don't know what he was referring to. Perhaps with the landing legs

“Forget Mars, I’m going to Ceres!”

So Kerbal. :D

Oh.

So I guess they're not doing a spontaneous Moon gravity assist and Mars intercept then. It will get pretty close to the Moon though.

I don't know... when you show before the launch that you are going to aim for an orbit that just touches Mars orbit, but then you put your payload into an orbit out to the asteroid belt...it kind of looks like a miss.

What?  Why is he going out to Ceres!?  Did he have more delta vee than expected?  How crazy is this!

The plan was to burn to depletion, so the whole system worked better than anticipated. This is how you test a rocket!

They said a long time ago it was going to go past Mars orbit.

All of those Starman photos just look so... fake! The Flat Earthers are really going to love this one. My new profile pic looks even more unrealistic because I played around with some sliders to get crisper colors.

Did I only imagine the plot they showed in the pre-launch coverage that showed the target orbit only going out to Mars' orbit?

I have to agree. It's like what might happen in KSP if you spilled your drink into your lap during your burn to Duna transfer orbit and you overshot your target velocity. Doesn't say much for precision navigation.

They also showed the Tesla doing a Mars flyby in their teaser video from just the other day.

Just think what that Moon + Mars flyby would have said for precision navigation.

Musk said in the press conference "you know it's real because it looks so fake". Said if it was CGI, they'd do a better job making it look real.

Is the car modified? There seems to be a support structure in the wheel well and the regular parts are missing. Is it a shell on a frame?

Looking at the two different YouTube feeds, the one with (currently) over 9 million views shows a duplicate onboard view from the boosters as they are landing...but the feed that has (currently) less that 15 thousand views correctly shows the onboard video from the two separate boosters. It also shows the opening of the fairing timed to go with Life on Mars better...although the other feed was showing the trajectories changing during boostback burn, which looked very KSP.

I especially like the onboard views of the booster separation, seeing the flaming engines of the core going by,  followed by a brief splash of flame onto the boosters from the core.

Confirmed by musk.  The center core only lit the middle engine and crashed.

So the FH launch was a partial failure.

As far as test flights go, I'd say they did pretty well, though.

Losing one of the boosters is not doing well in my book when you are all about reusable rockets. Today's launch was a partial failure.

They expected at least partial failure, so things went according to plan.

I'm not sure why you're so insistent to bash Musk and SpaceX, but they're going to be successfully launching rockets, whether you're sulking about it or not.

SpaceX believes that failure IS an option, and loves to learn from them.
