Thousands have seen the tower catch a Falcon rocket. The public can watch the launches from across the bay.

No one has seen a StarShip capture as they haven't attempted one yet.
Yesterday's flight was Starship's first successful flight.
StarShip is the biggest rocket ever built

Here's Johnny!

What I can't get my head around is that in the Apollo missions that allegedly went to the moon they did this with 1 rocket. Fast forward to 2025 and it will take no less than 11 or 12 rockets to accomplish the same feat (the new Starship is the most powerful rocket ever built from what I have read).

Not to mention how the Apollo missions survived the Van Allen radiation belt.

When you say 11 or 12 rockets, are you talking about rocket engines?


AI Overview
Just a quick photoshop size comparison between ITS, Starship ...
Starship's Raptor engines are more advanced, efficient, and use methalox fuel compared to the Saturn V's F-1 (RP-1/LOX) and J-2 (LH2/LOX) engines, which rely on less efficient, more traditional propellant combinations. Starship's system uses dozens of smaller, reusable Raptor engines for immense, flexible thrust, unlike the fewer, larger F-1 engines of the Saturn V, enabling precise landings and scalability. The Saturn V was a three-stage expendable rocket, while the fully reusable Starship and its Super Heavy booster are designed for extensive reusability and in-orbit refueling.

No actual rockets to complete the mission. They need to have a Starship fuel tanker in orbit, then it will take approximately 10 starship launches to fill the tanker. This is assuming they can transfer cryogenic fuel in space as this has never been done before. This is on top of the NASA Artemis rocket that is carrying the crew.

SciManDan talks about why it only took 1 rocket, and why the new mission might need more.

As did the exposed film they brought back! If you accidentally send film through a momentary x-ray scanner at airport security, it's useless. Also the eyewitness interviews of people that worked at the soundstages, and then saw their handiwork on TV during the missions? I'm not a flat earther, nor am I in the "all space is fake" camp that dissects each video from the ISS claiming to find flaws, but I have issues with the moon missions.

Back in the 60s, it was pretty easy to fool people - TVs were small and trust in institutions was EXTREMELY high. Especially if you were trying to beat the Reds at something.

So 12 launches minimum to reach the moon? I have not heard that before. Wild.

Mercury, Gemini, and Apollo. 

Apollo used the Saturn V platform. 5 massive Rocketdyne F-1 Rocket Motors each one with ~1.5m pounds of thrust to lift the vehicle. Each pump on each motor could empty an Olympic size pool in under a minute. 

Apollo 11... the 11th mission of the program. Not sure where you are getting 1 of anything.

Honest question I have NEVER recieved a genuine answer from NASA faked the moon landing or Flat Earthers; what precisely would it take for you to believe?

So... Apollo 11... you thought 11 was just a random number? 

A BIG part of the reason we stopped going was the expense. The Apollo program was insanely expensive.

We think we are so smart today, when in reality, despite the "progress" we have made in technology over the last 50 years... it PALES in comparison to what those that designed and built the U2, the A-12, SR-71, and X-15 accomplished. 

We have what we have today BECAUSE of those people in the 50's and 60's. 

People today take for granted you can Google almost anything. That said, try to find a CNC machine manual from say 1981. Before electronic manuals. If somebody hasn't scanned that thing, it doesn't exist. Maybe there's a copy buried in an archive somewhere but there's no guarantees. 

Now go back to the F-1 rocket motor... predates that CNC machine by 10 years. When almost all machined parts were done manually, machinist notes, welders notes, etc... that REALLY made those rocket motors actually run.

I could go on, and on, and in, and on ad infinitum about things we have lost over the years. Again, we think we're sooooooo smart today. We've convinced ourselves that we can overcome challenges with hubris.

It's possible that the scientists new the risk of camara film being exposed to radiation and made provisions to protect it. It took at least 11 rockets to get to the moon not counting the Mercury and Gemini programs. I'm not sure of the number because of the Apollo one fire.

We've been shielding film from radiation for a LONG time. 

When I was younger, I shot A LOT of film. I had a special canister for my film when I flew. Never once lost a single image. Film went through the X-Ray then they opened up the canister on the other side. No factor.

The belt has a narrow area, that's the spot they target travel through.

I read that we still can't replicate the inconel they mixed back in the late 50's/early 60's.
Back then, it was a little bit of this , a little bit of that, put it in the furnace  till the melt is just the right color. etc etc It was seat of the pants old school intuition all the way.

All those guys are dead and gone and today with all our science, computers and digital furnaces and thermometers
old school still beats it.... and they can't figure out why.
I read that about ten years ago.. maybe they've figured it out since then??

I remember reading a similar piece outlining how many of the shop drawings are gone now, not the originals, but the ones marked up with EXACTLY how it was done at the time. We all know about how much tribal knowledge can be lost this way, and I think this is one of the biggest examples of that.
