What did u explained? The raptor engine is yet to mature. The recent explosion more or less explain it. Using RD-180 engine is due to US backward in propulsion compare to Russia in space rocket. In fact, these rocket are not cheap. The Russian charge a high price for this engine sold to US. How can they passed up this chance to milk american?
Sourgraped. Our tianwen -1 don't use backward method of using foreign rocket engine but domestic YF-100 engine that send 5 tons payload to mars vs US 1 tons perseverance. So u are saying american are more backward than Chinese?

You need to thank Russia for perseverance success.
If not, NASA might need to wait for 2022 window.
Lol.. I know it's embarrassed to talk about US backward of rocket engine tech and come out with excuse like cheap and easy access.. loser always give this excuse.RD-180 is cheap and reliable, US purchase of said engines kept Russian engineers busy and away from the hands of rogue nations. We also got the blue prints thrown in and we now make superior oxygen rich engines. To conclude, we have the best oxygen rich engine and the best fuel rich engine.
Please continue to eat them delicious sour grapes.
The US Air Force, Lockheed’s main customer, demanded access to 10 key technologies needed to produce the RD-180, in case relations with Russia ever foundered and America had to make the engines itself. It was a big ask. The US was after a crown jewel of Soviet space technology, and the Russian government was not thrilled. “But they saw no alternative,” Sackett says, “because the country did not just have a change of heart, they went broke. They just went flat broke. This is how they saved the company.”
Can SpaceX and Blue Origin best a decades-old Russian rocket engine design?
The story of the RD-180, the big rocket engine that couldwww.technologyreview.com
We got the tech from Russia, meanwhile China is only able to produce 1/5 the thrust of the RD 180 for the same type of engine fueled by LOX/Kerosene .

When u have your full american tech capable of sending 5 tons payload to Mars then call me again. Btw, the backward China u claimed. Send 5 tons payload to Mars which u american still haven't demonstrated with your own tech first. The right to laugh at other reserve for Chinese/CNSA.

In the meantime, I just lol at you backward american in mars mission.
Cheap talk by american. Demonstrated first and proven in mars before u talk to me again. In the meantime, China is still the king of space with proven 5 tons payload to Mars.Your tears are delicious we now have the best kerosene lox engine thanks to our bro Russia.
5 tons is puny we sent much higher payloads into deep space. With our NEP and NTP engines we will get to MARS really fast 90 days with massive payloads 63 tons. China is not in our league go play with India.
New Recruit
With Blue origin's new glen rocket that's 7 meters in diameter and it's own BE-4 methane based engines, ULA'S new Vulcan rocket which will also use BE-4 as well. Then there's SLS, starship and many smaller launchers bring there own engines and rockets to the market astra, firefly, relativity, and vector by 2024 the US will have multiple next generation rockets active. An exciting time to be aliveCheap talk by american. Demonstrated first and proven in mars before u talk to me again. In the meantime, China is still the king of space with proven 5 tons payload to Mars.
Watch out for out Long march 9 ,140tons to LEO.

)Soyuz? The same spacecraft that send US astronaut to ISS for 9 years... While spineless US has nothing to send man to space during that period. You got the cheek to laugh at it? That means u are laughing at your own NASA incompetent?LOL!
Your only proven manned spacecraft is based on the Soyuz.
You have no permanent spacestation. We have had one for 20 years and even one in the 1970s.
You have not sent any spacecraft to other planets except for your Mars one.
Your Long March 5 is only slightly more powerful than a SpaceX Falcon 9...which we flew 26 times last year...and it lands too.
Falcon Heavy can launch 16.8 metric tonnes to Mars. That's like a +10x overkill for the Mars2020 Perseverance mission. Why would we use it?
Delta IV Heavy 8.1 metric tonnes to Mars. Again overkill.
AtlasV can do 4.9 metric tonnes.
Falcon 9 can do 4 metric tonnes to Mars
Next time send a rover the size of Perseverance...and make it nuclear powered too.

Oh and send some spacraft outside the Solar System too.

Stop avoid the fact, we send 5 tons to payload to Mars while you send only 1 tons perseverance. You can even double perseverance weight to 2 tons and it still cant beat our 5 tons payload to Mars. The highest payload to Mars on single trip so far. The record will hold until some other breaks it!
And we are not spineless space bragging power using foreign rocket engine and brag perseverance as some feat all by itself. lol...
