Nope. The savings on the refurbished booster don't make up for not getting paid for getting the payload on orbit. Looks like that's a good payload sep though - job done!

I would think it'd be considered a mission failure (Payload is the actual mission) with secondary objective (landing booster) successful Quote Link to comment Share on other sites More sharing options...

TheEpicSquared Posted June 23, 2017 Share Posted June 23, 2017 If the Iridium-2 mission date holds, then June would have a record 3 launches - CRS-11, BulgariaSat-1 and Iridium-2. Hopefully there will be even more once SLC-40 is back up and running. Quote Link to comment Share on other sites More sharing options...

StrandedonEarth Posted June 23, 2017 Share Posted June 23, 2017 Of course I was working during the launch. Glad to hear it was a total success. Those legs sure look flat, I'll guess that's there's no room underneath for the Foomba (Falcon Roomba). I'll watch the replays when I get home later, they should have full footage up if it's not already. Quote Link to comment Share on other sites More sharing options...
wumpus Posted June 23, 2017 Share Posted June 23, 2017 Has Spacex always used "fire in the hole" staging? Of course, main engine cut-off, staging, second stage ignition weren't simultaneous, but more like someone hitting the spacebar three times in succession without having time to check to see if everything was going exactly right.

The correct word is hot staging, you fire upper stage before disconnect, Russian rockets uses it, that is why they have an grind structure between the stages. Benefit is that you don't need trust to push the fuel and oxidizer down before firing either with the reaction jet or dedicated solid fuel engines. It will not work on Facon 9 as the insterstage is an long tube who also hold the grind fins for landing Quote Link to comment Share on other sites More sharing options...
CatastrophicFailure Posted June 23, 2017 Share Posted June 23, 2017 It looked like the upper stage had a pretty significant off-attitude kick it had to correct for, too. For all the talk of how light this bird was for a commsat, this seems like a very high-energy launch. Ive probably asked this before, but any idea what that assembly that goes up inside the bell of the upper stage MVAC is? Quote Link to comment Share on other sites More sharing options...
CSE Posted June 23, 2017 Share Posted June 23, 2017 http://www.spaceflight101.net/falcon-9-v11.html Quote The first stage of the Falcon 9 is connected to the second stage via a carbon fiber aluminum core composite structure acting as interstage adapter, housing the MVac engine of the second stage. Stage separation is accomplished via separation collets and pneumatic pushers in three interfaces connecting the two stages. SpaceX tries to avoid using pyrotechnics for separation events. Go to T+3:04 of today's launch: the commentator describes the separation as having "four pneumatic actuators". I'm convinced that central pole is one of them, so probably "pushers in three interfaces connecting the two stages" means there are three more actuators - near the interstage walls? - to bring the total to four. I guess there's more space available inside the engine bell to fit a telescoping ram long enough to guarantee the bell clears the interstage housing.

CatastrophicFailure Posted June 23, 2017 Share Posted June 23, 2017 So, given that the landing was hard enough to crush all 4 crush cores, that barge must have really felt it. The question now is, will they have to change the name? Quote Link to comment Share on other sites More sharing options...
