SpaceX hired all NASA's engineers and uses all NASA's technologies. China builds its technologies all by itself, given that the US banned any collaboration in space program with China. You bet that SpaceX launched a few more than rockets than China. Even that, China has a higher success rate than SpaceX in rocket launching. SpaceX explodes a little too often.
- seanmcdirmid 9y ago> China builds its technologies all by itself Well, if you want to be technical about it: they are using Russian designs and got help from Russia. Russian designs are also very reliable, which is why we use them ourselves.
- avmich 9y ago> they are using Russian designs Not at all. An important and telling detail: pintle injector is almost never used in Russia, but standard for Merlins. Or you can look into gas generator cycle, which isn't used for today's Russian kerosene engines except RD-107 family, which have separate components for turbopumps and pressurization.
- nkoren 9y ago> SpaceX hired all NASA's engineers and uses all NASA's technologies. Um, no, that's wrong. I'm thrilled for China's accomplishments and won't talk down about them, but your assessment of SpaceX is simply false.
