Launch now NET Wednesday, 5 July.

"Out of an abundance of caution, SpaceX will be spending the 4th of July doing a full review of the rocket and launch pad systems. The next launch opportunity for Intelsat 35e from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida is now no earlier than Wednesday, July 5 or Thursday, July 6. Additional updates will be posted to this page as they become available. "

They're catching a ton of heat for not letting their KSC Employees get July 4th off; but sometimes Aerospace matters require working through holidays. Besides, they get paid WELL for doing so -- and likely they're getting food and stuff catered in to make it up to the Employees. Not like they work in some kind of sweat shop, ya know. It's SpaceX. Space-friggin'-X. THE SpaceX. The ones who are actually getting things done in the U.S. Space Program.

 

I'd do it with a damn smile on my face. :yes:

Previous abort was ground computer limits database didn't match the flight software database. Corrected by adjusting the ground computer's limits.

 

Liftoff!!

Didn't appear to be the 126% throttle setting, but the 112% (Block-4) one. They might have eased into it later on (as evidenced by the staging speed), but the graph will tell the tale. :yes:

What's amazing is that Tom Mueller and his team has taken Merlin from,

 

Thrust: 94,000 lbf

Thrust/weight ratio: 96

 

to the fire breathing beast it is today with,

 

Thrust: 190,000 lbf 

Thrust/weight: 200:1

 

And this using a gas generator cycle, and they ain't done yet :woot:

 

SOB's been eating it's friggin' Wheaties.

Holy over-performance, Batman!!

 

 

The extra apogee will make the plane change to equatorial much easier!

does this mean they could have saved some fuel for a landing attempt?

Not really. The altitude + velocity with this Block 3 core likely meant the re-entry would leave nothing but pieces and smoke.

 

Block 5 is getting enhanced heat shielding, new coatings and those Ti grid fins (a block 5 part) to be more survivable.  This will up their game in F9 mode, but especially in the special Falcon Heavy version where center core ASDS landings will be way down range high, hard fastballs.

One of the interesting things of many that I read in the Musk biography was that Merlin uses a face shutoff pintle injector. Before, these types of injectors were used for low thrust RCS systems. SpaceX was able to get it to work with an actual high thrust engine saving weight by eliminating multiple shutoff valves.

Yup. And it took a lot of work by the propulsion engineers, many of which were convinced it wouldn't work. Of course it did, and SpaceX is now reaping the benefits.
