They did cost a lot more. The super optimistic cost projections for starship won't come for many years. A hundred million dollar per launch starship would be great, but a 50 million dollar neutron would be better for a five tonne satellite.

Which might happen sooner than you think.... If you fly in a 737 MAX!

You pay per launch, not per kg.
This is not your local farmers market.
To fly a 777 always costs the same, regardless of the number of passengers in the back.

This was also the case for Falcon9. But that didn't stop SpaceX from flying commercial payloads, did it?

It's their current operational rocket. It's not their new or next rocket.
Basically RocketLab has to hope that they get Neutron up and running well before Starship is eating up even the small sat market.

They also just started launching from wallops in Va.
I was lucky enough to see the inaugural liftoff in person.
Very cool

>SpaceX has invested at least 10 billions in Starship, including Raptor,
This was about Falcon9, tho.
And combined with the ISS contracts I would be VERY surprised if SpaceX hasn't recouped their development cost yet.

Thank you. I get that it was a stupid question but thanks for answering something that intrigued me :)

Ah the thing i have been waiting for..the real space race has begun..usually the one who starts things ends up in the bin and others take over...will be fascinating to see the new innovations and speed up.

Depends on which direction the solar winds were blowing 😀

Depends a bit on things not mentioned.
If earth was floating alone in the universe, it would spread out evenly and freeze to ice.
If earth was rotating, it would cause more water to be around equator (this is the case today).
If earth was orbiting the sun and had a moon, the gravity from these two bodies would also affect the water (tides).

Egypt is higher than sea level, therefore it runs south to north.

Cause Elon Musk's name is clickbait..dah
And SpaceX's too. That's the reason they mention them in this article and its headline

What innovations does Neutron have that F9 doesn't?
Also Starship is about a month or two from first orbital launch. Neutron is 2 years at minimum away. How do you see eactly Neutron launching customer payloads *before* Starship does?

Rocket Lab's website says Neutron will do 13 tons to LEO, not 15.

It is but that does not mean it can't be used commercially. They have been working on production methods for 2 years now so I suspect they are getting "produced effociently" down.

Launching a five tonne satellite on a starship won't necessarily be cheaper than a neutron. A 777 is cheap per passenger, it isn't cheap if you are flying 8 people.

There is a long road ahead before starship has rapid and reliable reuse and is being produced efficiently.

If I remember it right, the motion of water on earth, at least the oceans, is dictated by the tidal forces of the moon and the spinning of the earth, and sometimes also due to sub-ocean earthquakes. Regardless of the earth's shape, these forces would still be active.

>If you can send 20T to LEO but they only have 12T of cargo... You're going to go for the cheaper launcher.
Really depends on how much cheaper the smaller launcher is.
In a market where a 70% bigger launcher costs only a few millions more, it will make sense to increase the mass of your satellite/payload so you can massively save on development and manufacturing cost.
Because if your requirements stay the same but you can double the mass, your costs go down fourfold. (Roughly speaking)
