A correction. The report says
There are two separate contracts. The launch contract is about 5 (not 4) launches. The 5 seems to be correct because the following paragraph repeated 5 again, indicating it is not a typo by the author. The launch contract is 1.3 billion RMB, the 1.134 is final payment of the same launch package. The previously payed 166 million RMB was to reserve the production slot and key components. It should be calculated in the total cost of launch.
1.3 billion RMB means 260 million RMB or 40 million USD per launch excluding the payload. This is still better than F9 though.
Here is my calculation of cost per unit mass in GTO launch in million USD term.
F9 in its max capacity (new/reused)
Reusable mode Payload cap (tonne) New Rocket Cost per tonne Reused Rocket Cost per tonne Not reused 8.5 62 7.29 50 5.88 ASDS 5.5 62 11.27 50 9.09 RTLS 3.5 62 17.71 50 14.29
Payload cap (tonne) New Rocket Cost per tonne 5.5 40 7.27
F9 is only cheaper when using an old rocket without reusing. And that "cheaper" is not cheaper at all because that price is based on the fact that some previous customers have paid a higher prices before. For a particular customer 5.88 is cheaper, but averaging out, from both SpaceX's perspective and the market (all customers) perspective F9 is more expensive than LM-3B/E.
The exchange rate is nominal rate. If we use PPP rate which the Americans prefer to use, LM-3B/E would be much cheaper than F9 in every way.
From another angle, without Vitical Landing capability F9 as a rocket is not an outstanding rocket at all in all other regards.
I really didn't want to quote aspi, but I found this article on Wikipedia about Long March 3B cost. Do you think it may be true? It's pretty close data to data given by this contract of 40 m$.But a Chinese official told me in 2019 that improved processes and high production rates had driven the cost of CASC’s launches down in recent years to about US$50 million from US$70 million.
Thats an impressively low figure. I always thought that China's rocket launches were like the old NASA, non-innovative, and very costly.
I don't quite understand the question. What is true? The 50m usd by this article's claim? 40m usd is the contract statement in 2021. The 50m figure is in 2019 by the author's claim. It is only natural that the cost went further down over two years.
The low cost of CZ-3B is because the rocket development cost have been absorbed by over 300 times of CZ launches, now it is only cost of manufacturing. All the CZ-2,3,4 use the same engines and fuselage.40 million dollars is an excellent low cost figure for a rocket. Hopefully these new space companies can also deliver similar results quickly
Initial plan is 3 modules in a T shape. Each module is 20 to 22 tonnes at launch. Later launches by space craft will further add equipment and supply mass. There will also be cargo space craft and crew space craft docked to the station. At any time there will be a crew space craft docked. So the total mass is more than 80 tonnes.
The extended configuration, first extend the T shape to a cross (another core), then add more modules to the new core.我首先说基本构型，我们在2022年前后要建造的空间站是什么样子。我们有三个舱，一个叫做核心舱，它是第一个发射的。然后有两个实验舱。
