Regarding the heater strips that go on the SRBs. How would these look on the 5 segment SRB? I'm kind of stuck seeing how this would look. Is there a diagram?
If needed, the swoosh patterns could also be used for tracking rotation and alignment. There's no law that says the patterns have to be rectilinear.

Dynetics has announced the completion of the SLS core stage pathfinder vehicle. http://www.dynetics.com/news/497
From the UPDATE thread:Quote from: whitelancer64 on 08/30/2017 10:45 pmDynetics has announced the completion of the SLS core stage pathfinder vehicle. http://www.dynetics.com/news/497If they completed it, why don't they share a photo of it, instead of this rendering? (click on the update post to see the rendering)
Will it be painted to look like the flight article?

Great article, but lacking proper metric units. Don't want to alienate the rest of the world!
Oh of course the 'native' units (not wanting to get into name discussion) should be first, just think metric conversions should be mentioned too.
Jeff Foust@jeff_foustHoneycutt: SLS will be the backbone for US space plans for 30 years or more. #VonBraun
Jeff Foust@jeff_foustMike Griffin: don’t expect to see changes on the scale of 2010 (when Constellation cancelled.) SLS and Orion aren’t going away. #VonBraun
HUNTSVILLE, Ala. — NASA is still up to a month away from setting a new target launch date for the first flight of the Space Launch System, but agency officials said they still expected it to take place in 2019.NASA has not set a new date for Exploration Mission (EM) 1, which will launch an uncrewed Orion spacecraft on a test flight into lunar orbit and back, since announcing in May that it would delay the flight to 2019 after deciding not to put a crew on the mission.
