Anybody saw the 'Don't panic' thing on the Tesla? Made me chuckle, they sure have a sense of humor.

Saw the don't panic. Wondering if they packed a towel.

Makes my day that much better. Giving approval to that kind of lightheartedness shows great confidence in the team's ability and makes overall morale palpable. Well done.

Does anyone have a "top-down" view of the Roadster's (planned) orbit? I've read that it's on a Hohmann transfer towards Mars's orbital neighbourhood but haven't seen a diagram.

Ah thank you! I missed that. Here's a screenshot

I like everything about private space exploration except this: when we sent the Voyager golden record to space, we consulted with the great minds about which were the important landmarks of our civilisation. In this model, it's all about idiosyncrasies: the Voyager record had the Vitruvian Man, this has an astronaut on a sports car and largely-irrelevant sci-fi stories. Of course, private space probably means the who…

Voyager went interstellar. The Tesla is still bound to the inner solar system.

Of the centre core, these are the last few moments before it is lost from the feed. Smoke can be seen... https://youtu.be/wbSwFU6tY1c?t=38m20s ... and then back to the presenters. As someone said to me, "That's their lying face!" :) Can't fault them for wanting to dwell on the positives though, was an amazing moment to watch.

Can't fault them for sure, but it's strange for them. SpaceX tends to be very upfront with their failures, and tends to broadcast and in many cases re-upload video of their failures. Doubly so when the "failure" isn't part of the primary mission.

It wasn't a lie; they just didn't know the result. There have been multiple cases in the past when contact was temporarily lost after drone ship landing.

Yes, that was pretty SF. So, whats to stop them attaching an additional two (or more) to the existing rocket now that they have the basic synchronization worked out.

Musk has said there is no reason they can't attach two more in the future.

That would be simply Kerbal.

Still don't understand this waste of ressources. Waste of ressources to build this Tesla Roadster. And then the waste to kick it into space. It is not that we are littering our earth itself. We now do it in space as well.

ADVERTISING.

The amount of coverage both Tesla & SpaceX got from launching the Roadster equates to advertising costing considerably more than the cost of the car.

The feed quality drops in a way that makes the shaking antennae explanation seem plausible. I doubt the announcers knew then (why not just say so unless there was some ambiguity?), but it must have been a distinct concern, hence their 'smile nervously' reaction. It is a bit odd they haven't announced that it was lost yet, but I agree that seems very likely.

FWIW the drone ship feed has been lost in exactly the same way every time I’ve watched a landing.

> car is in orbit. That is correct...but NOT in orbit of our home planet!

My understanding from the diagrams they showed is that the orbit is a wide one (oval) around Earth that passes near Mars.

It has just burned again to raise apogee, and will burn a third time to switch from earth orbit to a transfer orbit (edit: or perhaps the next orbit is the final Earth-Mars orbit?)

Center core lost, announced on internal feed https://www.youtube.com/watch?v=-B_tWbjFIGI&feature=youtu.be...

At this point in that video, some minutes after the loss of signal, you can hear on the countdown net https://youtu.be/-B_tWbjFIGI?t=42m21s - it's garbled but sounds like "Suspected loss of signal".

They were the same. Don't know if they did this intentionally. I actually watched them for two minutes for that, and was 99% sure they're the same image, just translated a bit. The final confirmation came near the end, when the other booster entered the view, and you could see for sure, both rectangles streamed from the same camera.

They certainly looked very similar (as they would from that height) but the thruster firings were not at all synchronised (I thought the same thing, until I saw that).

Here's proof they were the same- coming in to the same pad
