Thx as always for ever more links to information. They recently
attempted launch from two pads on nearly the same day, I am wondering
what the turnaround time is for boosters these days, and how much
inventory they have. If they can improve their cycle time, 9/month
seems achievable on the 3 pads they have, aside from conflicts with
other launches.
rykllan posts infographics for most launches (not just SpaceX) but for SpaceX
launches she shows the history of the booster used, including the turnaround
time for each launch

for tonight's launch, the refurb times have been 47, 44, 55, 55 48, 250 days
(going back in time)
SpaceX just leased SLC-6 at Vandenberg (Shuttle, Delta pad) and has stated that
their plan is to set it up to be able to launch the Falcon Heavy and Falcon 9
I think their biggest limiting factors are pad availability and landing barge
availability.
Random thought - other launch sites long term? This was built to great
fanfare a while back

Virgin Galactic has had a pause on their flights for a while. I understand that
they are soon going to do another employee only flight, but then expect to be
able to start carrying paying customers

It's heavily used by the ESA, but with the fallout from the Ukraine war, ESA
lost access to Russian rockets that were launched out of there. They are almost
out of Ariane 5 rockets to launch from there. Ariane 6 was supposed to fly in
2020, but they are now hoping to launch the first one late this year (or next
year)
And: https://en.wikipedia.org/wiki/Kwajalein_Atoll
Pegasus is pretty much dead, there was a mission a couple years ago that was
carefully tailored to be a match for the Pegasus @$25m launch cost, but SpaceX
won the bid and used a dedicated Falcon 9 (it's not public what the winning bid
cost, but we can infer from the Pegasus marketing material and their failure to
win the bid)
I think that's just too far from the ability to generate fuel for any serious
launch capacity.
