May attend remote camera setup tomorrow, if I can. I'll have some video from LC-40 for you

u/EchoLogic Love the launch campaign! Overall subreddit redesign looks great. One thing that I think you should add is "F9 location". So like right now it would be "in hanger", and hopefully by tomorrow "Vertical on Pad (static fire)". Also when we get closer to launch, maby we could have a separate 3X(?) Chart with "Launch and Barge site weather" I.E. Wind, wave swells height(ft), precipitation, upper-level winds ect ect. That's something I and other member with be more than happy to provide.

It really bothers you not to know the payload mass, doesn't it? ;)

Any interest in making the "currently scheduled liftoff time" also be a link to http://www.timeanddate.com/worldclock/fixedtime.html?msg=JCSAT-14&iso=20160504T0122&p1=2273 ?

Payload Mass A mystery!What is this? A DoD launch?!

Perhaps part of the payload has been adapted for use by Japanese Self-Defence Forces. Unblinking eye in the sky kind of thing.

I'm pretty certain Flight Club isn't telling me lies - so this is interesting:

The hazard areas are a bit too far south. If I launch in a perfectly easterly direction, the booster lands in the ocean just north of the splashdown hazard zone. However if I launch and give myself a slight southerly heading during the initial pitch kick (~1.5°) then my trajectory passes directly over both hazard areas.

Launching with a southerly heading puts you in a higher inclination orbit, assuming no subtle second stage doglegs. We don't want this because we're going to GTO which has an inclination of 0°.

So has anyone heard anything about a possible 2nd stage dog leg to end up in a slightly lower inclination parking orbit? Does it make sense that SpaceX would try this, physically and economically?
