Delayed a month again?  If th dry fire is in Jan, then the launch won't be until Feb.  

The "official" launch window for Mars is more like March-May, I'm curious how close NASA is willing to let them get a "dirty" rocket near Mars (although a *tiny* bit of aerobraking would be ideal for making sure Teslas never rain down on Earth).

Remember Zuma?

We already knew it was pushed to 2018 when Zuma got delayed.

@wumpus They're not launching anything to Mars.

Assuming Elon Musk is not pulling a fast one on all of us to begin with, they're launching something "to Mars orbit". In other words, apoapsis high enough to reach out there, but not actually encountering Mars. Intentionally avoiding Mars, even, if I were to guess. Elon did say it would be "in space for millions of years". You can't get that without making sure you won't accidentally smack into the planet whose orbit you're aiming at.

FH with roadster has a ton of margin, they can actually do a real transfer to Mars, but this is likely just going to the distance of Mars, not actually to Mars.

Not so sure about millions of years in space. Eventually it's going to get an encounter with either Earth or Mars.

Mars is easy enough to avoid, even if AP is outside mars the plane also have to match. Now it will always intercept earth orbit unless you do an correction burn some distance from earth and the upper stage has limited durability not only because of battery but also cook off and probably other issues.

Looking better for a late January launch of the Heavy.  I'm going to be in Daytona the last weekend.  Man that would be great if it happens then!

Yeah, just a touch of off-plane inclination will help keep it out of intercepts, but it will still cross Earth orbit now and then. 

But computing a trajectory which has no Earth encounters for millions of years is not that hard to do. Not when you're SpaceX. Just need a fast computer.

Do you have those problems with microstutter, too? Every second it seems to miss about 0,2sec of video, making it very hard to watch without getting annoyed...

Technical webcast is nothing but the regular webcast without voiceover. No differences in shot or telemetry.

Sooty rocket lifting off...beautiful sight!

Through Max-Q. MVac chilling.

Correct me if I'm wrong, but will this be landing on the landing pad,? Or is it the barge?

All CRS missions will be RTLS from now on.
