China's Space Program News Thread

Hawaii is under occupation by the US. We both agree.

I suspect our definitions of agree may disagree.

Great juxtaposition between the embarrassingly weak Space endeavors of Taiwan to their inane and hilariously bad reaction to the gloom and doom leveled against the Chinese rocket landing.

OK this was what I was expecting and sure enough if the demand is there, it will happen: Mass Production for satellites.

Next, we'll see if rockets will get the same treatment as the auto industry. Or, have a fleet of space planes for deployment.

The lower angular resolution makes any light dot on the sensor blurry than Hubble, instead of lighting up one pixel, it lights up 4 pixels (just say it).

Should be the other way around. Having larger FoV mean more area is covered by a pixel. So the same area will light up 1 pixel instead of 4.

Resolution is not the be all and end all of a telescope. Lower noise floor, image stabilisation, optical quality are all very important. Having higher resolution is useless if your telescope cannot resolve the image to the level that benefit from it.

Also interesting is what the telescope can reveal spy satellite technology.

the Tianwen-1 probe intends to choose an opportunity to land ... in the period from early morning Saturday to Wednesday Beijing time," the China National Space Administration said in an online statement.

Wait. I thought that the landing would definetely happen tmr. So there is chance the landing could happen anywhere from Saturday to Wednesday?

Bummer

It's in China's interest to be cautious. They get one shot at this.

True, I just felt quite disappointed. I had put up an alarm clock for it.

Anyway, hope we get some advance notice so we can be ready for it

Isn't FoV and Angular resolution different things? FoV is the angel that the lens covers. Angular resolution is the lowest angel that the lens can differentiate two closely positioned light source, the lower the angel the higher the resolution. Having a larger FoV does not necessarily mean a higher or lower Angular resolution although when everything else equals higher FoV does lead to lower angular resolution.

That is right.

There is a specific window for the landing. If they don’t do it on the 15th then they have to do it on the 16th or 18th.
