'Scope on the Moon's surface

Many of us will remember the days when anything marked 'Made in China' pretty much guaranteed it was treated with disdain - the quality was hopeless and the useful life of the product highly doubtful.

China's technological leaps over the past 1-2 decades are simply breathtaking.

Good article Dean, thanks for that-

Wouldn't it be awesome to image a galaxy or a Nebula for a dozen days straight without interruption, only a few thousand subs to stack.

"since the moon rotates 27 times more slowly than the Earth, the scope can stay fixed on the same star for a dozen days without interruption"

It still is rubbish.
No doubt they are quite capable of producing quality when they choose to, but they usually don’t.

Pretty general and sweeping comment there , yes but like everything in life, whenever it is made 'You get what you pay for ' .
I have had a Chinese made ute for 5 years now and clocked over 100,000 km and it has not missed a beat .
6 months ago grabbed a Chinese CFMoto 650nk , 12,000 HARD !!! Km later , no problems , they can do it. , just look at the. SW Esprit series. .

Brian.

Ben - I take it you can manufacture, assemble, launch & land on the surface of the Moon a better-quality robotic probe which would also out-last the 2 years which Chang'e has accomplished?

Good onya!

Well obviously for you "made in China" is a mark of distinction. Enjoy.

I wonder if that is just a very low res image they released? They are certainly capable of better optics and electronics than this photo would indicate.

LOL. Somebody has a chip on their shoulder.

In regards to Telescopes and eyepieces their optics have come along way over the last 1 and a half decades. Their quality can even challenge(not surpass) some of the best optics available to consumers.

Last I checked. Isn't China where all that shiny expensive Apple products are made?

Dust was a major problem in ALL the Apolla landings. Well documented. Better read up Blindman. They are not talking about landing blast dust, they are talking about static charged dust, that causes all kinds of mayhem.

blindman your just making a fool of yourself , spouting stuff that takes seconds to show is wrong.

For those of you following at home here are some pictures of Apollo astronauts covered in dust.

That dust was kept and analysed too.

If they managed to get a robot to drag space suits around on the lunar surface, then that's probably a bigger achievement than astronauts going up there and getting dirty themselves.

"There are none so blind as those that will not see.."

Your eyesight might be a bit dodgy Blindman, but try to have a look at this from 13:00 minutes onward (Apollo 12 sequencing camera recording lunar module approach & landing).

https://www.youtube.com/watch?v=kFSa6vUix70

Pete Conrad later described the landing as in "IFR conditions".

This means the crew had to use Instruments (the 'I' part) rather than VFR ('Visual Flight Rules') because the dust was so significant that nothing could be seen outside by eye.

This guy is somewhat like a Collingwood supporter whose team lost by 15 goals, but claim they should have won, because a poor resolution photo shows that the ball might not have actually scraped the goalpost early in the second quarter.

Oh, you DO need to see an ophthalmologist!

I have circled the dust and particles in your picture for you. Notice it is the same colour/shade/hue as the lunar soil all around the foot pad.

If you cannot see it, then truly you DO want to believe the delusional conspiracy garbage.


If English is not your first language, I am willing to write in a couple of other languages if you prefer - I can write fairly well in English (), Russian, French, some Suomen kieli, bad Deutsch, poor Tagalog and a very small smattering of Latvian.

Added another feature in your photo - this shows the blast flaring and streaking of the lunar soil by the decent engine - circled in GREEN

Lewis, maybe you are right, maybe not. As we cannot prove anything, it doesn't matter - it doesn't change your life anyhow. I would expect from someone to do research on both sides. If you follow money trail and million things which could go wrong, it just does't add up.
If they were on the Moon, nothing big was achieved (maybe military, but I doubt).
By the way, first comment was just sarcasm :-)
Cheers all.
