Why does Dragon need any markings? There's no other commercial vehicle flying.

CBS 60 Minutes ran their previous SpaceX piece again tonight, with extra footage of the COTS2+ mission tacked onto the end.
Still touching to see Elon get choked up when asked about the opposition to commercial space from his boyhood astronaut heroes...wonder if the success of COTS2+ has softened any opinions there.

Apologies if this has been covered already. I haven't yet worked my way through all of the SpaceX threads (uncharacteristcally I know). Actually just watched the launch for the first time just now. Believe be when I say I'm swamped!
My very technical question:
At 49-54 seconds, what is the flame from the upper stuff...
wb go4mars, I have a better question. Can LOX be used to pressurize? Past times the valves are closed prior to launch and LOX is not seen out of the valve.

I think that's water being vaporized lit by the exhaust. IIRC the condensation from LOX tank area melts and moves to the base of the LV during flight. You can also see water dripping down after the 2nd stage was ignited later.

I think it's air rushing down by the LOX tank that still has enough time to cool down for water vapor to form. This brings me to something I've been wanting to ask: why haven't we seen launch replays from this tracker or, for that matter, why have all the other shots in launch replays been cut off before MECO?

I don't know if this has been posted jet, but when you look at SLC40 (Falcon 9 launch site at KSC). You see a falcon 9 (cargo version) on the launch mount. And when you look it up in Google Earth you get the image i've added.

We discussed that about a year ago. Some people thought it wasn't a coincidence that they got a picture of F9 on the pad venting.

So when should we expect Dragon to arrive at McGregor?

It probably did 2-3 days after returning to land.

Probably just because they added a more recent photo of the pad itself on top of older surrounding imagery.

That's because you're looking at a 3d rendering of the launch pad and Falcon 9, not just a satellite image. If you turn off 3d buildings in Google Earth, it will disappear. EDIT:I mean, it's a conspiracy!

Haigh-Farr provided antennas for the COTS-2+ Dragon, and Falcon. http://spaceref.com/news/viewpr.html?pid=37613Since 2007, Haigh-Farr has proudly worked with SpaceX in developing antenna systems that are used to provide flight safety, telemetry, tracking, GPS and video on Falcon9, as well as command control, telemetry, GPS and other communication functions on Dragon. On both previous launches, and during this most recent launch and docking, Haigh-Farr antennas successfully provided dramatic live video feeds as well as telemetry and other communication links. As a testament to the quality of the SpaceX technical team, continuous contact with Dragon was maintained with the NASA TDRSS network of communication satellites used to transmit and receive data.
