Have we previously seen this sort of hemispherical cap on the second stage?

It can be found on page 15 Section 3.3 of the Falcon 9 Users' Guide - it's known as the Payload Attach Fitting (PAF).

Not quite. The PAF goes in the same place and has the same shape, but is very different functionally. Also, Dragon doesn't use a PAF, so they wouldn't put one on a booster for a CRS flight.

Here's a closeup of what it looks like, from Jason-3.

It's different for a Dragon/Trunk setup as shown in this SpaceX photo

I want someone to get to bloody KSC and take a bloody picture of this rocket on the pad!

Travis actually that it's going "veryical" right now, so ...

On another front, the live feed (of color bars) from SpaceFlight Now just went to black for a moment or two, then back to bars. I think I too may go back to bars...

So can we assume that since it is staying vertical, whatever caused the delay can be fixed on the pad? That would point to a minor issue, I hope.

"NLT " Sunday? Could you explain what NLT means to us uninformed folks? Not Less Than?

The Falcon 9 rocket has been hoisted upright at pad 39A for a static fire test, which si now scheduled for some time Saturday.

This marks the first time a rocket has stood on the historic launch pad since July 2011, when the last space shuttle blasted off there.

The picture below was just shared on Instagram by SpaceX chief Elon Musk, who wrote:
"Falcon 9 rocket now vertical at Cape Canaveral on launch complex 39-A. This is the same launch pad used by the Saturn V rocket that first took people to the moon in 1969. We are honored to be allowed to use it."

Very exciting to see this!

And it seems like the tower structure really is at a perfect height to install a crew access whiteroom and arm.

You can really see how much of the RSS interior has been removed. A lot more than most realized, I think.

Can't wait to see this baby light tomorrow!

Excellent article.

Are they using the TEL to hang the crew access arm off of? Or are they using part of the RSS?

Neither. The crew access arm will be part of the FSS and the RSS will eventually be gone.

Great articles CG! Thanks for the ABCs (lettering of the pads). Find that a great bit of the history of 39a and 39b.

daveglo · « **Reply #194 on:** 02/10/2017 11:18 pm »

So, apologies if this has been discussed already, but since the new TEL will do a "throwback" at launch, would we expect to see that trick during the static fire? I wouldn't think so, but that would be a pretty impressive sight if it did.

cscott · « **Reply #195 on:** 02/10/2017 11:29 pm »

Discussed; no certainty but majority opinion was that throwback was only after hold downs released. Thus, not during static fire.

IanThePineapple · « **Reply #196 on:** 02/10/2017 11:32 pm »

So will the Falcon stay vertical until tomorrow orrr...?

For launches from 39A will the SpaceX LCC at CCAFS be used exclusively or will any part of the LCC at Complex 39 be used?

darkenfast · « **Reply #198 on:** 02/11/2017 10:15 am »

I don't believe we have seen any evidence that SpaceX is using anything other than their own Launch Control for 39A. The LCC next to the VAB at Kennedy is going to be used for the SLS.

On a different note: this launch will set a record for the least powerful rocket to be launched from 39A!

what are the blue cylinders at the bottom of TEL?
shock absorbers for kick back at T-0?
