If it doesn't register on the Richter scale, it's not a rocket.

Nah, the Richter scale goes all the way down to "can only be picked up by instruments", which isn't that awesome. Real rockets register on the Fujita scale, whose lowest point is F0:

Small trees are blown down and bushes are uprooted. Shingles are ripped off roofs, windows in cars and buildings are blown out, medium to large branches snapped off of large trees, sheds are majorly damaged, and loose small items are tossed and blown away (i.e. lawn chairs, plastic tables, sports equipment, mattresses). Barns are damaged.

If I'm not entirely mistaken, some of SpaceX's activities have qualified for this already.

I'm more and more of the idea that Spacex designed parachutes that are too effective and 3 of them deployed slow down the ship so much that the 4th doesn't bite enough atmosphere until it is very low and the pressure gets high enough to deploy the last one

Worth mentioning that the original Dragon design had 3 parachutes, it was NASA that recommended putting 4 along with a few other things (like less windows)

Starship isn't beholden to NASA's design tomfoolery

Not to mention, one of the main reasons SpaceX ditched going from chutes to propulsive landing is the existence of Starship

So clean now with the covers over the engines.

Starship gazer has a great view too

Just now, Spaceception said:

Wow, I'm really behind on things, when did the engines get covers? Are they there to prevent corrosion, or just to look nice?

There's cover in the holes that were above the engine, looking like cocktail shakers. Needed during ascent because aerodynamics

The engines have also been coated to look nicer and prevent corrosion from the nearby sea

The fact that we can film a craft 80km high traveling at - what, mach 10? 

Amazing. 

As I understand they use the mount for an radar tracked anti air gun and replace the gun with an telescope, might beefed up the radar a bit as range will be longer but you will also be aiming directly at target. 
It should have an way to select target so you don't follow dropped stages and fine adjustment,

We point telescopes at comets, and they are much further away and moving much faster.

It's an angular tracking issue, comets have high velocity, but small movement across the sky. You could have a scope that could follow ISS, but not a car going 1000 times slower past your house.

Yeah, I know. That was my point. The farther away the rocket is, the less difficult it is to track at high speed.

This is for the ship's downcomer, any idea of what it could be? Looks like some kind of filter

I'm going to take a wild guess and say that these are supposed to keep froth out of the downcomer immediately after the flip.
