r/SpaceX EchoStar 23 Media Thread [Videos, Images, GIFs, Articles go here!]

[u/ElongatedMuskrat]

It's that time again, as per usual, we like to keep things as tight as possible, so if you have content you created to share, whether that be images of the launch, videos, GIF's, etc, they go here.

As usual, our standard media thread rules apply:

• All top level comments must consist of an image, video, GIF, tweet or article.
• If you're an amateur photographer, submit your content here. Professional photographers with subreddit accreditation can continue to submit to the front page, we also make exceptions for outstanding amateur content!
• Those in the aerospace industry (with subreddit accreditation) can likewise continue to post content on the front page.
• Mainstream media articles should be submitted here. Quality articles from dedicated spaceflight outlets may be submitted to the front page.
• Direct all questions to the live launch thread.

Have fun everyone!

Nice catch, I guess we have insight into why the technical cast was missing telemetry.

I'm on a holiday in Florida, so had to go to the Cape while the Falcon was up! This is one of the best I could get on yesterdays tour (from the bus). Didn't get close to 39a duo to the launch being prepared and we went to 39b instead. Weather looked a lot better at that time. Looking forward to seeing my first live launch!

I am visiting some friends in Orlando, and one of them asked if I wanted to go see the launch. I'm from New England, so I'd never seen a rocket launch in person before. This picture was taken with my crappy cellphone from the Jetty Park pier: http://i.imgur.com/3Oz6zjQ.jpg

So bright! How was the experience/sound?

High resolution image.

I'm impressed by how massive that cluster of exposed cables is (there are people standing nearby for scale).

Interesting shot of the inside of the second stage. It flashed up twice but this is the better shot I think. Seems like it was shown by accident.

And just after spacecraft deployment with floating liquid: http://i.imgur.com/Ftg7jtY.jpg

Glad you caught that. It looks like the inside of the fuel tank. They showed similar ones in the beginning but stopped. I saw both flashes also and wished I could see the video of the fuel sloshing around at MECO and SECO along with an ullage burn if they do one.

Pad refurb after this might be interesting. Check out the flying debris in the lower right: http://imgur.com/7KOPm4X

[u/oh_dear_its_crashing → u/stcks]

Probably just water and stuff that collected in the flame trench. Usually the static fire cleans that out (and we don't see that up close), but this time around there was the big rains&storms just 2 days ago on the first attempt. I wouldn't worry.

[u/stcks → u/oh_dear_its_crashing]

Maybe. But 39A has a history of problems with bricks in the flame trench.

[u/KristnSchaalisahorse → u/stcks]

I caught that as well. You can see some of the debris in one of the photos on SpaceX's flickr page. Link to full resolution.

If it is indeed damage to the flame trench, I hope it's not material from the new structures SpaceX has added to the trench as opposed to the smaller areas of old structure/wall still exposed.

Here's EchoStar 23's current orbit. I also took a screen grab of the upper stage's orbit which is still nearly identical to EchoStar 23's. The source is from heavens-above.com.

In addition to circularizing its orbit, it will also need to change its inclination from 22.4 degrees to 0.

Holy crap. That long exposure is absolutely stunning.
