I don't see how; there are really no show stoppers on the list, just precautions to preserve reasonable public access to the beach and mitigate light and noise pollution, as well as make sure SpaceX is taking the proper care to respect the historical and natural landmarks in the area.

Unless I missed something, the technical challenges of launching Starship remain the long pole in the tent.

We shall see how it plays out; the regulatory burden being imposed on SpaceX is substantial.

I agree with Robert. Given the scale of what SpaceX is trying to do the regulatory "burden" placed upon SpaceX is minimal. For anyone that is aware of the inner workings of large scale development projects this is almost a "get out of jail free" card.

The assorted species biological protections make good logical sense, and are not particularly difficult to do. While Cape Canaveral/KSC did not have significant environmental laws when they were first developed, you can bet your bottom dollar that biological protection of the area has become much more restrictive over the years, thanks in part to the "Earthrise" photo of Apollo 8.

As an aside, if you actually read the 40 page report in the link, it is amusing to see how some of the interest groups were bought off for absolute chump change... $5,000 here and there... for "free" fishing tackle etc.

To me perhaps the biggest constraint placed upon the project is the 500 hours per year closure limit on the highway, with, up to, another 300 for "anomalies." It would not surprise me, that if SpaceX has made it safely through a given year with no major anomalies, that they may claim some in December, to add some extra hours for highway usage.

From Elon Musk (via Twitter):
Starship will be ready to fly next month. I was in the high bay and mega bay late last night reviewing progress.

We will have a second Starship stack ready to fly in August and then monthly thereafter.

Has a study been conducted on the effects of an exploding, fully fueled Super Heavy booster on the area surrounding Pad 39A at KSC? Could debris from such an event damage the Pad 39B launch site as well?

I might also be concerned that a launch or landing mishap involving the Super Heavy booster might take out the Falcon 9 launch pad facilities and there would be no place from where to launch manned Dragon flights.

I guess that I do not have a clear understanding of SpaceX's launch facilities plans at KSC.

My guess is your question(s) stem from the Reuters report of a week ago that NASA wants SpaceX to ensure its plan to launch Starship from Florida will not put at risk the infrastructure needed to supports Falcon 9 flights to the International Space Station.
"We all recognize that if you had an early failure like we did on one of the early SpaceX flights, it would be pretty devastating to 39A," Kathy Lueders, NASA's space operations chief, said in an interview of the agency's discussions with SpaceX.

SpaceX did not return a request for comment.

SpaceX has already invested heavily in building a Starship pad some hundreds of feet from pad 39A's launch tower. It has responded by pitching NASA on a plan to outfit its other Florida pad - Launch Complex 40, five miles away on Space Force property - with the means to launch U.S. astronauts, according to a person familiar with the plans.

The company is also studying ways to "harden" 39A, or make the launchpad more resilient to both an explosive Starship accident and the immense forces emitted from a successful Starship liftoff, Lueders said.

Hardening the 39A pad and launching humans from pad 40 would both require agency approval.

"SpaceX is working with us on those things," said Lueders. "Because it's also in their best interest to not have what is a pretty steady source of income for them become interrupted."

The reality is SpaceX is a year (or more likely, more) away from being ready to launch Starship from Pad 39A, so there is time to address NASA's concerns and take precautions as necessary.

Thanks Robert. I did not see the Reuters article to which you refer. I recently ran across my file with the Saturn V "Fireball" estimate/report and started thinking about how much greater a Starship/SuperHeavy fireball/explosion might be.

I wish SpaceX well with their upcoming test launches. I fully expect the first several to go Boom, but I hope that SpaceX figures out the issues and gets the Super Heavy/Starship combo working properly.

What SpaceX is attempting to do is truly mind boggling, and I hope they are successful in bringing this rocket to full commercial success.

I wonder what the two linear stripes of no thermal tiles on the Starship are for? Those sure looks like two potential points of failure.

Something looked to have gone wrong with today's (July 11) testing of the SH7 Super Heavy booster as it resulted in an unannounced ignition event, but according to Elon Musk (via Twitter), it was just "booster engine testing."

Elon Musk (via Twitter) later acknowledged things didn't go as planned.
Yeah, actually not good. Team is assessing damage.

SpaceX completed a seven engine static fire test with its Super Heavy Booster 7 at Starbase in Boca Chica, Texas on Monday (Sept. 19).

From Elon Musk (via Twitter):

Booster 7 now returns to high bay for robustness upgrades and booster 8 moves to pad for testing.

Next big test is probably full stack wet dress rehearsal, then 33 engine firing in a few weeks.

SpaceX is starting work to host cargo and crew Falcon 9 launches from Space Launch Complex 40 at Cape Canaveral Space Force Station, SpaceNews reports.
At a Sept. 26 briefing, Bill Gerstenmaier, SpaceX vice president for build and flight reliability, said the company had already started preparations for the upgrades needed at SLC-40 for cargo and crew launches. "We've already started the work to begin the preparations for pad 40. We've ordered some hardware, put some contracts into place," he said.

He didn't elaborate on the work needed to prepare SLC-40 for cargo and crew missions. "We'll do cargo first. We can do that fairly easily," he said. "It gives us some flexibility to move some things off 39A, which helps us balance launches off both pads. We'll add crew at the right time."

From the NASA Advisory Committee meeting on Monday (Oct. 31), some of the steps remaining before the first Starship orbital test flight:
  • Booster 7/Starship 24 re-stacking
  • Additional single-species prop system testing
  • Additional de-stacked static fire tests (including Booster 7 33-engine test)
  • Wet dress rehearsals
  • FAA license processing in work

Starship completed its first full flight-like wet dress rehearsal at Starbase today [Jan. 23]. This was the first time an integrated Ship and Booster were fully loaded with more than 10 million pounds of propellant.

Today's test will help verify a full launch countdown sequence, as well as the performance of Starship and the orbital pad for flight-like operations.

After completing Starship's first full flight-like wet dress rehearsal, Ship 24 will be destacked from Booster 7 in preparation for a static fire of the Booster's 33 Raptor engines.
