> Plus it's obvious that the US government is doing everything in their power to have Musk on as short of a leash as possible. What do you mean by this?
Some people are confused and think the government is against Musk in some way like the public is. The government quite likes SpaceX.

From the booster's point of view, the catch is a target location and speed. Plus a set of tolerances: however much the arm can swing to catch it, and horizontal speed has to be really low because it needs to drop down vertically into the arms. I would expect that the target on the ocean, even for the first test, is very specific. Once the booster can hit a phantom target, they can change the target to the tower and g…
I imagine that lack of stable reference points would be an issue on the ocean. Both for the algorithms under test and for validation. (I liberally use "algorithm" here as the superset of both algorithm and the hardware it runs on, I think in reality these tests are mostly for correcting parameters that are hard to determine with sufficient accuracy on paper) If you want to write off an entire booster, adding a dummy…
You know what I'd like? I'd like a launch which said 5 4 3 2 1 lift off! All systems nominal, flight proceeding And what were going to get is: 5 4 3 2 1 lift off of what will be, for all humankind the first tenuous steps into the void, as mankind proves the value of endeavours against odds... I can supply my own poetry. I don't need the emote which appears to be now mandatory.

Outdoor cats are a menace to birds and other wildlife on a scale that's hard to describe. It would be hard for an individual homeowner to do anything else that is even nearly as destructive to their local wildlife than keeping an outdoor cat.
Not in locations where wild cats exist anyway. If wild cats exist in your area, the bird life has already adapted to them over the past millions of years. Obviously, if cats in your region have been introduced by humans, that's an entirely different situation.
All felines aren't exactly interchangeable either. Domestic housecats are naturally extant only in the Middle East, but everywhere else they have been introduced by humans.

You would need to build a second tower with catch arms there. The booster does not have landing legs and will not touch down on the ground, the plan is to have it settle on the same "tower arms" that are used as a crane to stack the booster and the ship for launch, with engines still well above ground.
They managed landing legs and they decided to up the level of difficulty a few notches or something?

Outdoor cats live much shorter lives than indoor ones.
But are they happier ones?

SpaceX will typically livestream a "Technical webcast" simultaneously, which only includes audio from the ground support loop without any hosted commentary. That's what you're looking for.

Good GPS in ideal conditions (no trees or buildings blocking/bouncing signal) has accuracy on the centimeter scale: https://www.gps.gov/systems/gps/performance/accuracy/
That link tells us that the signals are intended to be sent with an accuracy better than 200 cm 95% of the time. Using more frequencies only really helps avoiding errors from bad/misleading reception, so it's hardly relevant in "ideal situations".
Long term stationary receivers can resolve to millimeters, but dropping rockets from orbit isn't exactly a thing that would be considered "stationary" in this context.

Can you post a link for this or is it a simple search?
