It's Boeing, so free to use.

MM is Boeing-related? I mainly just want to make sure I'm crediting and linking to the primary source.

AFAIK, No. MM is reposting photo and video from Boeing Media Room site.

Gotcha. Anyone have a direct link to the source?

Most photo and video in Boeing MediaRoom requires login credentials (http://boeing.mediaroom.com/)

Chris might know where the originals are as I have no clue.

Please forgive my lack of imagination but why is there a need to keep the launch time secret for so long? We will be able to see the launch so it doesn't stay a secret. X-37B is large enough to be easily tracked even without knowing the exact launch time. What is the reason to drag this out?

I imagine it's to do with other countries on orbit reconnaissance assets.

Do we think any implications for the webcast? Eg only short notice just prior to the webcast of when it will be, or even no live webcast, just a recording later? (although I imagine there'll still be people posting on twitter when any venting is observed)

Yeah, Boeing's always had a login for media (found mine again) and that's all it is. Fine to reproduce on a news media site (which we, you and MM belong to). Just credit Boeing, job done.

The login is just a throwback to years ago.

Prevents other nations from pre-positioning assets which may move slowly.  An orbit takes ~90 minutes, so obscuring the exact time may cause an unfriendly nation to have a particular asset on the exact wrong side of the planet (180° out of phase).  In fact, they may be delaying the choice of the exact time in order to ensure that this happens.  Some cat and mouse.

Space weather question re: sunspot active region 2673

Has there been any mention of whether solar activity will threaten tomorrow's scheduled launch?  AR2673 is facing Earth ("geoeffective").

AR2673 produced several M class solar flares on September 4 UTC, with the associated coronal mass ejection (CME) striking Earth today and tomorrow.

Earlier today, the same AR produced a X2 class solar flare, followed by a X9 class solar flare at 1202 UTC.  It's unknown as of my post whether or not this flare produced a CME.

http://spaceweather.com/

EDIT to add mention of today's X2 class flare, kevin-rf's post, and the gif attached to his post.

I think SpaceX just lost control of the X making machine, The sun just beltched out a long duration X2 and X9 flare...

As always, this is a weather factor that is monitored each launch.  There are limits for solar weather, and if those are breached, Falcon 9 won't launch.  Exactly what those limits are, I'm not 100% sure.  I know that's not a terrifically detailed answer, but that all I have.  Hopefully someone else can expand on this.

So the bottom line answer to your question is: Yes, this will be a factor for tomorrow's "go/go no" conditions.  But it's important to remember that it's always part of the "go/no go" factors.

What's up with the grid lines in the logo - or is it simply gaps between stickers? And if they are gaps, why did they do it that way? (the gaps are too consistent to be just random poor alignment)

Thanks for the confirmation! For posterity, a Reddit user helped me find what is likely the original source on DVIDS, a distribution branch of Defense Media Activity. Includes a nice little bonus timelapse at the start :)

The only difference is we currently have a sunspot group churning out some quite strong flares. This is not commonly the case. That said, if another strong flare occurs during the count down I would head over to the Party thread to see what the betting odds are on a scrub. I strongly doubt they launch during a large M or X class flare.

But that is a decision for SpaceX to make.
If you're happy and you know it,

Some info on today's large solar flare. I'm afraid it doesn't mean much to me ...
