SpaceX Falcon 9 : CRS-12 : Aug. 14, 2017 : UPDATES

[Jakusb]

Congrats SpaceX on another amazing and seemingly perfectly executed launch AND landing!
Keep up the amazing work you are doing! Can't wait to see the first CRS on a re-used core, FH Demo flying and many other bold moves into the future!

Pretty Good landing video!

Where was that video shot from? Looks like a great place to watch a landing.

The sonic boom arrives 11 or 12 seconds before landing.
This is MUCH earlier than what was experienced at OSB-II, which is 10.5 miles (~55 kft)
12 seconds is ~14 kft, and if there was a 5 sec delay at the OSB-11 (just guessing) that makes it ~20 kft closer for a distance of ~35 kft or ~6 miles
Jetty park is ~ 5 miles from LC-1.  Rt-401 is about 6.5 miles.
For those that have watched, which does it look like?

One of the payloads being carried inside SpX-12 is Cuberider 2 from Australia. Our media probably went a little overboard on the importance of this payload!

"SpaceX launch: Australian high school students play major role in NASA's resupply mission

The commercial SpaceX rocket, owned by entrepreneur Elon Musk, launched from NASA's Cape Canaveral base in Florida today, and on board were a series of experiments devised by Australian school students."

This landing video was shot from LC37B:

Looks like it is coming down real slow.

Pretty fancy setup they used for that video!

LC-37 is twice as far from LZ-1 as the USAF station is... over 4 miles away.

I regret that I have but one Like to give to this video. Utterly fantastic tracking job! I watched the final burn through landing half a dozen times!

At 6:17 of the video, there was a little fire from the central engine for about 3 seconds. That was between the reentry burn and landing burn.

I believe that is just them running LOX through the engines for chilldown or to help avoid FOD.  Hot soot + LOX = Flames

Great footage during descent!  Check out the brief appearance of the vapor cone / Prandtl-Glauert singularity at the 6m45s point, and how it immediately collapses upon engine ignition.

Thanks guys!  That was my video, I guess I should post future videos to the forum as well.  I'm still working on improving the setup, including a proper scaffolding around my table to keep glare off my monitors and some improvements to the intelligence of the tracking algorithms.  I also plan to distribute the tracking software in the near future for anyone with a similar telescope.

Yes you should!




Like the screen name, too...
