China Completes Its First Lunar Return Mission
China's Chang'e 5-T1 mission to the moon has not only taken some beautiful pictures of the Earth from the craft's perspective (hat tip to reader Taco Cowboy) but as of Friday evening (continental U.S. time) returned a capsule to Earth. (The capsule landed in Inner Mongolia.) From the linked article: Prior to re-entering the Earths atmosphere, the unnamed probe was travelling at 11.2 kilometres per second (25,000 miles per hour), a speed that can generate temperatures of more than 1,500 degrees Celsius (2,700 degrees Fahrenheit), the news agency reported. To slow it down, scientists let the craft "bounce" off Earths atmosphere before re-entering again and landing. ... The module would have been 413,000 kilometres from Earth at its furthest point on the mission, SASTIND said at the time. The mission was launched to test technology to be used in the Change-5, Chinas fourth lunar probe, which aims to gather samples from the moons surface and will be launched around 2017, SASTIND previously said.
How curious that this comes in the same week the Americans lost two space vehicles in one week.
The future of space belongs to China. They are the ones with the cajones to do it. They'll be the first manned mission to Mars too because they'll just fucking do it. They won't be crippled with fear and pork.
China 2014 = USA 1960.

Oh shut up. They've managed to do something we did in the 1970's. Good for them, it's not a trivial accomplishment by any means, but it doesn't mean that Taikonauts will be owning near space for the next millennium. I do wish them luck and persistence - somebody needs to kick the US in the kiester and get us 'competing' against something.
Besides, the Chinese love pork.
Faster! Faster! Faster would be better!
1972 Last US Moon Landing
1972 - No one does a damn thing
Nope, I don't really see any reason to pick on China specifically there.
At this rate they will be inventing the wheel in about 200 years but good for them because the rest of us will have forgotten how to do even that!
But don't worry, we still have junk food and reality TV.
US has never had an unmanned sample return mission from the moon. Soviets did, though, in the early 70's.
They can spin it, "US sucks, they have to send up humans because their robots are too dumb."
Table-ized A.I.
Just accept that the Chinese will own the 21st century of space exploration, ok. There's no need for your envy, be proud of our achievements as a race and commend China for taking the lead, for all of us.
And don't bring up the "we did it before you"-bullshit, because the Russians beat ALL OF US going into space. The Russians had crafts in orbit, people in orbit, and landers on the Moon, Venus and Mars, before anyone else. The Russians were the definitive pioneers of space exploration, period.
You're just some small envious person who have no idea what you're talking about. The U.S has been doing monumental spying for 50 years via the NSA, and most of your achievements are the fruits of European and Asian immigrants. Your suggestion that the Chinese can't achieve anything on their own is something only a clown and a loser would come up with.

It's a gorgeous photo, no matter what.
Congrats China!
I think we can actually pin the blame on Korolev here. He died in 1966, and without him Soviet space program lost their main driver.
And without stiff and successful competition he provided, US didn't use the same resources as before on space exploration after clawing their one victory after series of losses. A very smart thing to do considering the costs of the program and the fact that people only remember your last victory, not the string of losses that came before it.
The rest of the world seems to have become so risk adverse and cost focused that it is very doubtful any significant space exploration will be forthcomming in the near future. Perhaps what little communal pride is left in China will help spur exploration for explorations sake, and not just the pursuit of profit?
Time is what keeps everything from happening all at once.
AFAIK, today, even the US is back to the pre-1970 era. IIRC, NASA has lost knowledge about the Saturn's engine. Even in the nuclear domain, the industrial knowledge on how to produce some critical element of nuclear warhead has been lost.
Actually, no, it would seem the US were finally able to re-manufacture FOGBANK after 10 years and nearly $100 millions spent. http://en.wikipedia.org/wiki/F...
Go China! A scientific victory for any of us is a scientific victory for all of us. Congratulations and keep up the good work!

Finally, and China got in before India!
The government - if that is the word - of the middle Northern American country, colloquially known as the Americas [sic?], has decided to refrain from participating in any so-called "Moon race" because it "reminds them too much of the novel 'The Stand'", and any reference to 'The Trash-Can Man' does NOT refer to "the National Aero-Spatial Agent... - What do you mean that's not what it's.. Turn off that micr."
People lost interest in seeing men walk around on the moon, or riding around in a golf buggy. And they had picked enough rocks to last a while. What reason would there be to keep going ?
Wrong: the specs are still present, and much of the institutional knowledge is still present.
What the US lacks is the financial will however, rest-assured that both the US and Russia could hop back into the space race whenever they chose. It would hurt financially, but they could do it.
These countries are choosing not to spend as much on space programmes as they once did. Back against the wall, they could switch priorities.
I wish people would stop playing-out their fantasy that former world leaders (US, UK, Russia, France) are wounded giants with buzzards surrounding them ... they pack a mean punch and will continue to for some time.
Seriously, if you want 40 year old news, we can pretend to talk about Apple Is when it was an assembled kit instead of an available retail computer.
Oh my god, it's not full of stars... Seriously though, how come there are never any stars? Is the surface reflection really that bright, or are space-cameras just inherently shit?

If the problem was only economical, there wouldn't be a problem nowadays for a new launch vehicle to go to Mars. The $6 billions NASA budget in 1966 would be equivalent to $43 billions today. Even at FY 2013 budget, $17 billions, assuming the R&D had already been done, documented, and tooling still exist, the saturn launch vehicle could easily be re-made. But strangely, it could not. you are also disproved by the fact the NASA engineer have only been testing the Rocketdyne F-1 engine quite... recently... http://www.nasa.gov/exploratio...
Let's face it, the US space program is not what it used to be, but hey, if you like to live in the past, good for you :-/
You seen Peking recently, I mean RECENTLY? I didn't think so. No one can see anything in or around it. It's freaking like 100 years ago, only after 100 years of dirty coal burning and toxic chemical spewing.

says Los Angeles, the dirtiest city in the US, is cleaner than the 45 "cleanest" cities in China. Boycot Wal*mart and it would make a dent. Maybe.
And they had picked enough rocks to last a while. What reason would there be to keep going ?
Because the rocks wouldn't last for 5 seconds if they shared them with everyone who wanted to have a look at them.
If bringing samples back from the moon was trivial then looking at moon rocks through a microscope would be something we did in high school. That is however not the case.
I'm not saying that it would be useful to have enough stuff to make it possible for high school kids to do destructive tests with it in chemistry classes, but if the teacher talks about what the moon consists of there should at least be a sample at the school to look at.

Clearly after going to the Moon, someone discovered there is no point anymore to go there. USA proved its superiority as intended when JFK launched the program. The only incentive was national superiority during the Cold War. The rest was pure waste of money and resources.
Comparison with aviation does not hold water. The aviation industry has proven to be profitable and fast transportation valuable to human activity and economy. No such thing exists for manned missions to the Moon or even Mars. In short, there is no incentive to do it again or even go to Mars, Cold War is over.

Hop!
Even if they continued the missions, bringing samples from the moon would still be way too expensive to be handing them out to school kids.
AFAIK, today, even the US is back to the pre-1970 era. IIRC, NASA has lost knowledge about the Saturn's engine.
You mean the F-1? The funny thing is, NASA never had a lot of knowledge about the engine in the first place: the computers of the time were not powerful enough to allow them to simulate a lot of stuff, so a lot of the design decisions were simple guesswork. (The same actually goes for the Russians, too.) Here's a great article on a recent piece of "industrial archeology".
Ezekiel 23:20
That Earth-Moon shot reminds me of the end credits of Gerry Anderson's UFO, complete with Eurostyle/Microgramma Roman and Bold text AND creepy-as-all-hell Barry Gray soundtrack.
Don't forget the Gong Man for Rank Film Processing!
Was that "alien planet" prop at the end remodeled as the Moon for Space:1999?
I think the polite term you're looking for is "empirical". And even if you could have sent a modern laptop to 1965, did they have powerful enough models in the first place? I'm thinking they had basic math in place but all the laptop would have done is arrive at the same answer faster, not arrive at new answers because the math/computer symbiosis needed decades to develop the complex models we use now.
I think it's part of the problem of how things are done today, we simulate things down to the quark level and as a consequence we take far longer to end up with things 10% or 15% "better".
It took far fewer people and less time to build Champlain Bridge here in Montreal 50 years ago. It was a good enough bridge for half a century and the only reason it's being replaced is because of poor maintenance and corruption (In Montreal? No way!)
The replacement bridge will apparently cost 10 times more (in equivalent dollars) and take far longer to build, but we already have dozens of CGI in all the newspapers.
Computers allow us to dream more at the expense of actually doing things.
It's an unintended consequence, I think the early computer pioneers failed to factor in the mediocrity of the general population when they envisioned the future of computers. You read about the "augmentation of the human intellect" by the early pioneers and it's naively touching to read. They failed to realize the "augmentation" of human laziness and greed.
Actually, the F-1B engine seems to be progressing nicely.
Ezekiel 23:20
Well, it depends on what "15% better" means. If it means "15% better parameters, regardless of 30%-60% higher manufacturing costs", it will be bad. If it means "15% cost improvement while keeping the parameters the same or somewhat better", that sounds like a better deal to me. I wouldn't blame computers for computer abuse.
Ezekiel 23:20
Nice how you compare post-industrial revolution, outsource everything to China USA vs China.
Now, go back and look at the past when the US had lakes and rivers actually catch fire during its manufacturing hayday.
How's that US spy program using NAZI spies working out for your PR?
http://www.nytimes.com/2014/10...
Most countries wanted the justice system to review them for war crimes.
The US wanted to protect them so they could spy on and ultimatly smuggle them back to the US and grant full citizenship, then deny they did this.
Why don't you cow tip him?
Forget the Moon, who knew there was actually an inner Mongolia ?
You can't fire everyone in a project and use new hire and expect everyone to understand what's going on. That essentially what's happening if you dropped a project for 30 years or so. Not like you have a full paragraph for every line of code explaining why you do it that way and what other ways that doesn't work. That last part is experience gained with the project during the development.
Neither do specs cover all aspect of a design. There are always some flexibility in that to allow for some engineering. Having one does not mean having a full design *is* just something the design *needs to do*.
Welcome to the 1960s, China.
Brilliant news, find water on the moon and we have found the moon's rocket fuel. Get that rocket fuel back to earth and use it to accelerate a craft to escape velocity, in the safety of the vacuum of space and we are on our way.
Please read my thesis http://dollyknot.com/nonlinear...
It's called an elephant's trunk whereas it is in fact, an elephant's nose, a nose by any other name would smell as sweet
And the Russians tried and failed to land on the moon. Their N-1 moon launcher exploded twice on the launch pad and Russia packed it in and called going to the moon quits. China isn't doing anything except following with their stolen technology in the footsteps of others. Instead of these moon stunts lets see China build a domestic jet engine. Building a reliable jet engine is something the Chinese have been unable to accomplish
"It would seem the US were finally able to re-manufacture FOGBANK"
As with the manufacture of seamless tubing for SSMEs there was heavily reliance on the memory of retired staff.
Not the first technique that was lost and certainly won't be the last.
"What the US lacks is the financial will"
Not just the financial will. Even with an unlimited budget the USA could not resume manufacturing SaturnV-class launchers without at least a decade lead-time.
For what it's worth, before the "space race", the USA was planning the Dyna-soar project, using a truly massive booster (Sea Dragon), which would be fabricated in a shipyard. Long-term that kind of booster is going to be needed, unless the political will to build Orion-class launchers is somehow found (and short of a Footfall scenario I can't see that happening)
"NASA engineer have only been testing the Rocketdyne F-1 engine"
No, they've only been testing the gas generator from the engine. Firing the entire engine will take a LOT more work.
Just to clarify: The "gas generator" is the part of the engine which drives the turbopumps which supply fuel+oxidiser to the main combustion chamber. It's analogous in some ways to the high pressure injector pump in a diesel engine.
As one commentator put it "Even if there were gold bars stacked at the landing site ready for collection, it still wouldn't be worthwhile making the flight to collect them"
The issue was that the space race was about militaristic chest-thumping and was promoted as such. Because of that, interest was lost as soon as Apollo 11 landed. The USA had won, why bother with anything more?
There were plenty of opportunities to keep interest up but the media had other priorities and exo-geology still doesn't feature highly on their radar.
