On November 14, SpaceX successfully completed a full-duration static-fire test of 14 Super Heavy rocket engines for the first time. "Next test is ~20 sec firing with max oxygen fill to test autogenous pressurization, possibly one more static fire, then orbital launch attempt", Elon Musk revealed.
After all, "For the first orbital launch, our goal is to get into orbit without exploding"
“To be totally frank, if it takes off without blowing off the stand, Stage Zero, which is much harder to replace than the booster – that will be a victory. So, ‘please do not blow up on the stand”.
Indeed, even with 33 engines on Booster firing is now a big problem with SpaceX Stage zero.
Let's analyze everything about this in today's episode of Alpha Tech:

As we discussed in the last episode, concrete chunks were immediately falling to the ground after the test of 14 engines on B7 recently. Besides, we can see that the paint blasted off on OLM. Fuel line insulation burnt at the bottom.

However, that is certainly not the biggest nightmare.
In the future, with all engines on Booster 7, that means 33 new “Raptor 2” engines capable of generating a total of ~7600 metric tons of thrust, almost certainly making it the most powerful liquid rocket ever tested.

Even if all 33 engines never reach more than 60% of their maximum thrust of 230 tons, they will likely break the Soviet N-1 rocket’s record of 4500 tons of thrust at sea level. It would also be the most rocket engine ever simultaneously ignited on one vehicle.

However, the danger to this bet is immense.
Even NASA worried that a Starship explosion near LC-39A could cut off the space agency's only means of launching astronauts to the ISS, therefore its desire for a backup launch pad.

Remember about Saturn 5, there was a good reason why the Saturn 5 flame pit was so huge and why the rocket was so high off the ground.

There are more than a few popular myths that have permeated the annals of space history, including one that the launch of the Saturn 5 rocket was so loud that the sound itself melted concrete and set fire to grass more than a mile away. Sadly, as many myths go, that's simply not true.

Researchers at Brigham Young University (BYU) in Utah have created a physics-based model of a Saturn V rocket launch to estimate its acoustic levels, determining that it had a value of 203 decibels. That nearly matches NASA's own recording of 204 decibels, based on a test of the Saturn 5's first stage run at NASA's Stennis Space Center in Mississippi.

For context, sounds above 200 decibels are extremely loud — an ambulance siren hits 120 decibels, while jet engines average about 140 decibels at takeoff, according to the National Institute of Occupational Safety and Health. "Decibels are logarithmic, so every 10 decibels is an order of magnitude increase," BYU professor Kent L. Gee, lead author of a paper on the team's research, said in a statement. "One hundred and seventy decibels would be equivalent to 10 aircraft engines. Two hundred would be 10,000 engines!"
