54 years ago today, a Saturn V almost went down.

As Apollo 6 rose into the sky, the vehicle began to experience violent pogo oscillations, ripping apart sections of the Spacecraft Lunar Module Adapter. However this was only the start of the problems. The Apollo 6 Saturn V climbing into space. The Adapter between the S-IVB stage and the Command Module can be seen with severe damage due to the extreme pogo oscillations. The vehicle managed to survive first stage flight, and successfully ignited its second stage. Not long after ignition however one of the J-2 engines began to suffer performance losses. The computer commanded the engine to shut down in order to prevent a catastrophic failure. Image

Saw some concern earlier about SLC-6s flame trench holding up to Falcon Heavy due to Delta IV Heavy having significantly less thrust, I'd like to put that to rest.

That's right, its Flame Trench History Time! (All photos from @SLDelta30 on the National Archive unless noted) There are currently two flame trenches with three main ducts at SLC-6. The first, currently unused one, is a 90 degree curved duct put in for the Space Shuttle, where the SSME exhaust would be directed to the right side of the stack during initial ramp up.

Looking at the future for CCSFS/KSC and 2026 is looking like it will be a *hell* of a year down here based off of initial projections.

On the low end we're looking at 60-80 launches, but on the upper end we could see more than 120!

This is how 1/12 Falcon: 50-70

39A is likely to continue seeing a rather steady 20-25 launches a year due to its conversion needs for Dragon, and Falcon Heavy.

SLC-40 will likely see a solid 30-40 flights, only being used for Dragon on an as-needed basis (Conflict with FH or other Dragon) 2/12
