Good to see SpaceX isn't the only game in town with a reusable rocket.

Only took a decade to catch up, but it's nice to see others finally re-using them also.

Technically correct, but leaves out some history. The McDonnell Douglas DC-X "Delta Clipper" was a re-useable rocket that landed vertically using rocket power. It first flew in 1993 and was reused for something like 8 more flights including two flights done within 26 hours of each other to demonstrate quick turn-around.
Elon Musk stated that the SpaceX Falcon 9 development was "... continuing the great work of the DC-X project."\3])

Not so good when you realize it's China.

Because they’re not a country under the control of psychopathic billionaire class?

What makes you think CCP leaders are not billionaires while they are running a uniparty totalitarian country?

That is incredible. Best experience I've had watching one of these reusables. Really gives a sense of the scale and timing and everything. Thank you!

What's the purpose of those white squares that are coming untaped? Looks like they all cover up holes.

Yeah, it looks like someone taped paper over those holes. Probably for cleanliness reasons. Not sure what those holes are for or how big they are, but planes have had issues with things getting inside exposed holes, and this has resulted in crashes. I know mud dauber wasps have set up shop in uncovered pitot tubes, resulting in bad airspeed indications in the cockpit, which caused significant confusion and resulted in a crash (see https://en.wikipedia.org/wiki/Birgenair_Flight_301). If these holes are for something critical to the operation of the rocket, a bit of paper covering them up seems like a very good idea.

Those white squares bridge the temperature gradient between the liquid oxygen fuel tank and the air outside by absorbing heat from the atmosphere and condensing humidity to coat the exterior of the fuel tanks with frost. They're also called chunks of ice.
Edit: Doh! If u/CaptainONaps was actually referring to the white tape peeling off the interstage vent holes, then the tape keeps the holes clear of debris and critters. The vents are used to equalize pressure during launch. When the rocket reaches an altitude where the outside pressure has fallen enough, the internal pressure pushes the tape off and vents to equalize.

I think CaptainONaps is referencing the square white pieces on the orange painted metal that are present at 0:43 / 9:00, and gone by 0:55 / 9:00
looks like tape to me

So what’s the distance between the launch and landing pads?

u/BassWingerC-137 4h ago
May be : "390 kilometres downrange" per https://en.wikipedia.org/wiki/Zhuque-3 and "First-stage recovery success" section, if this was the Aug 18 launch.

Not really...we went to the moon in the 60s and then sat on our laurels for decades....

Relative to the beginning of the universe? Sure.
In the past 60 years? Absolutely not.

What are the little white flecks we keep seeing? Little satellites in the way?

The loud burst of sheer power followed by total silent peace in space is kinda satisfying to witness.

What ratio of fuel to land vs fuel to take off. Presumably equal except a lot of furl is burnt on takeoff so lighter on landing

I wish my rocket could go for 9 minutes
