Skylon Posted April 28, 2017 Share Posted April 28, 2017 Old thread merged with the BO and Orion thread. This is the new one. Useful links: r/SpaceX Wiki Long list of acronyms Quote Link to comment Share on other sites More sharing options...
monstah Posted April 28, 2017 Share Posted April 28, 2017 Allright, lets try this out again. It seems like the old threads will stay glued, but we believe the new ones won't give you trouble. *turns thread back on* *steps back cautiously* Quote Link to comment Share on other sites More sharing options...
YNM Posted April 28, 2017 Share Posted April 28, 2017 Wow. Allright... So, to start, is this the only SpaceX thread for now ? Quote Link to comment Share on other sites More sharing options...
CatastrophicFailure Posted April 28, 2017 Share Posted April 28, 2017 Fancy that, in after the lock... Getting back on track here, NROL-76 launch this Sunday at waytooflarpingearly:00 AM PDT, your timezone may vary. Quote Link to comment Share on other sites More sharing options...
tater Posted April 28, 2017 Share Posted April 28, 2017 This launch is going to have the shortest ever stage 1 burn... Merlin change? Quote Link to comment Share on other sites More sharing options...
CatastrophicFailure Posted April 28, 2017 Share Posted April 28, 2017 Hmm, where'd you see that? Could the payload just be that light? Quote Link to comment Share on other sites More sharing options...
tater Posted April 28, 2017 Share Posted April 28, 2017 Dunno, it was posted at NSF (not L2). Quote Link to comment Share on other sites More sharing options...
sevenperforce Posted April 28, 2017 Share Posted April 28, 2017 I, for one, suspect uprating of the Merlin 1Ds in anticipation of Block 5. Quote Link to comment Share on other sites More sharing options...

Scotius Posted April 29, 2017 Share Posted April 29, 2017 Hmm. Maybe this mysterious payload is a spysat aimed at North Korea? On Molniya orbit it will hang above Pyongyang for hours. Considering current tensions about NK's nuclear and rocketry programs, i wouldn't be surprised if NRO wants to keep watchful eye on them. All of this is very "cloak and dagger" stuff Quote Link to comment Share on other sites More sharing options...

How is the fairing and payload attached to the rocket? SpaceX uses horizontal assembly like Russia does, but NRO payloads are designed for VAB who spacex don't have, I assume its plenty of assembly to fit fairing with payload on rocket.

All of this is very "cloak and dagger" stuff I think Molniya orbits work with countries with significant East-West width. Like Russia, USA, Canada (possibly China, but they manage with a single time zone). Not so much with North Korea, but you could claim a China-watching Molniya was supposed to look at North Korea (and indeed spends plenty of time doing so).

All of this is very "cloak and dagger" stuff North Korea is at about the same latitude of northern California, no need for a Molniya orbit, those are for high-latitude locations like a big chunk of Russia and the poles. I'm quite NK already has it's own dedicated satellite in GSO run by the NSA and the rest of the security alphabet soup. Which also happens to be a good place to watch Russia, China, etc. Whatever this bird is, it's been in the pipes for quite a while, probably long before Lil' Kim popped up and started waving his big rubber sabre around. Most of the articles I've seen say it's probably just a high-latitude comm relay, anyway. 1 hour ago, magnemoe said: How is the fairing and payload attached to the rocket?

There was video of the rocket being raised this morning, so this payload was definitely the standard horizontal integration. IIRC SpaceX actually has plans to modify 39A (b?) specifically for vertical integration of future NRO payloads. Quote Link to comment Share on other sites More sharing options...

StrandedonEarth Posted April 29, 2017 Share Posted April 29, 2017 I wonder if they'll try any fairing recovery on this one. Quote Link to comment Share on other sites More sharing options...
insert_name Posted April 30, 2017 Share Posted April 30, 2017 (edited) Seems to be a circular high inclination orbit on the payload faring. Could the booster do that within reason based on the current launch azimuth? Edited April 30, 2017 by insert_name Quote Link to comment Share on other sites More sharing options...

Could the booster do that within reason? @tater said that NSF said that it's gonna be the shortest 1st stage burn ever, and I also read the second stage is going to re-enter "right away" over the Indian ocean, so I'm guessing the payload has its own boost stage and the whole thing is very light, lighter than a Dragon. 2 hours ago, StrandedonEarth said: I wonder if they'll try any fairing recovery on this one. We won't get to see separation, so..... Maybe the fairing IS the payload.... Quote Link to comment Share on other sites More sharing options...
