I would jump to the conclusion that they make drag without side thrust or nasty turbulence.

EVERY TIME SOMEONE SAYS DEGRADING THINGS ABOUT MUSK:

I ASK THEM:

“YOU REALLY WANT TO BAD MOUTH A GUY WHO CAN SEND UP A ROCKET & THEN HIS EQUIPMENT CAN CATCH THE BOOSTER “WITH OPEN ARMS” FOR REUSE???” REALLY?????

HOW MANY SUCH BOOSTERS DID NASA DUMP INTO THE OCEANS?

HOW MUCH POLLUTION WAS THAT???

yep, it would be 100X easier to colonize Antarctica than mars.

The only major advantage is air: much of the Earth's surface is profoundly inimical to human life in terms of temperature and water availability.

Humans engineer our environment to make much of the Earth habitable and support a large population, especially through agriculture (the most environmentally damaging of all human activities). Mars has plenty of water locked in ice. You just need power to generate air, water, and habitation.

But there’s an inside component so that probably helps a lot.

These booster updates are not related to the recent failures of the second stage.

That just makes Antarctica 100X less interesting.

Mars ain’t the kind of place to raise your kids.

In fact it’s cold as Hell.

Explain the photographs of the Apollo landing sites by the Chinese, Japanese, and Indian recon satellites. I know you wouldn't believe those made my US assets.

My take is that the catching arms is what makes the fins unnecessary.

“ There is no air to breathe on mars, temps are extremely hostile to humans, and no water to grow crops”

Sounds like West Texas and Eastern NM. We get along fine.

For one thing, just because there are 33 of them doesn’t mean that they are small engines.

Mass (kg) 1525
Thrust (t) 280
Chamber pressure (bar) 350
Specific impulse (s) 350
Engine only TWR 184

Gotta have that kinda kick because:|

https://en.wikipedia.org/wiki/SpaceX_Super_Heavy

Block 3 Super Heavy
Height 72.3 m (237 ft)[4]
Diameter 9 m (30 ft)
Propellant mass 3,650,000 kg (8,050,000 lb)[4]
Powered by 33 × Raptor 3 engines[4]
Maximum thrust 80.8 MN (18,200,000 lbf)[4]
Specific impulse SL: 330 s (3.2 km/s), Vac: 350 s (3.4 km/s)
Propellant CH4 / LOX

it carries this on top:
