I've seen speculation it could have replaced an existing sat or refuelled it.

But basically we'll never find out, spacex done their job so all good.

Well the new spacecraft's cloaking device is working like a dream. cool


I'm pretty sure that if there had been a problem with the second stage, they'd have put everything on hold while they investigated.

Back to Falcon Heavy. I highly doubt SpaceX will live stream the test fire, as they'll likely be tinkering around with it and all the fueling systems for some time. Hence the 6 hour test window. No doubt other people will though and there will be official video later on, if it all goes OK.

They'll livestream the actual launch though obviously.

Not a completely daft theory. Claiming that a classified intelligence satellite failed to reach orbit could mean that its existence is forgotten about. The truth is out there. hippy

I've read that the 2nd stage was observed re-entering pretty much where it was expected to - if the payload was still attached wouldn't its mass have affected the de-orbit burn and caused it to overshoot the expected re-entry location ?

Looks like FH static fire has been delayed 24 hrs

"Sources at Kennedy Space Center say a notice on the Falcon Heavy static-fire confirms an attempt for tomorrow. More importantly, it suggests that the hold-down fire of the rocket's 27 Merlin engines will last 12 seconds."

That's going to be hard on the pad, got to be at the far end of what the cooling systems can do.

12 seconds is very long for a regular Falcon 9 test fire, but they're not starting all 27 engines all at once. They'll be ignited in stages.

They normally test fire Falcon 9s for only 3-4 seconds on the launch pad. They're just to check function, not capability. Commercial aircraft run their engines up at the start of the runway for the same reason. If nothing goes bang, they release the brakes and go for take off.

But without which a static fire wouldn't be static wink

They static fire for long enough and once it loses enough fuel mass, that thing is taking off clamps or no clamps.

A Dragon capsule (CRS-13) is due back on Saturday morning from a month at the ISS. The recovery boat is already on its way out to sea.

Hopefully SpaceX is now large enough to have different teams for all these different activities!

Any news on Zuma?

Reddit has some informative threads on zuma and SpaceX in general.
Nice of Mr Irridium to publicly stand up and denounce the legacy launchers smear campaign against SpaceX..

The CRS-13 Dragon capsule splashed down safely in the Pacific earlier. It's the second time a Dragon capsule has completed two flights.


Unconfirmed report that the Falcon Heavy test has been put back again to Monday. I assume they mean the 15th Jan.

And that's just the static fire, thing alone knows when they'll attempt a launch.

Frustrating, but better safe than sorry I suppose. At least it's not holding up the pad or the horizontal integration facility for other things.

There's an Atlas 5 due off from neighbouring SLC-41 on January 18/19th, so SpaceX aren't going to launch until after that anyway.

They've got a Falcon 9 due off on the 30th Jan from SLC-40 at the Cape, so that will likely take priority if the Falcon Heavy launch gets too close.

There seems to be an air of expectation over Falcon Heavy, with some online correspondence (not here) showing signs of frustration and even boredom.

Hate to tell them this, with rocketry, boredom is good.

REALLY GOOD.
