If the two stages survive long enough to do a splashdown, will SpaceX attempt to hover them over the water until they run out of fuel? Will there be splashdown video?

According to the flight plan published by SpaceX, the booster is going to attempt a hover in the gulf to simulate a landing, while the Ship isn’t going to slow down at all after reentry and will impact the ocean at a high velocity.

Tragically off-topic, but following the link I see that SpaceX has an online shop. The shop sells a SpaceX sticker pack, and one of the stickers looks like a bunch of cats in a satellite dish. I'm not a SpaceX follower, so can someone who is explain what it means: https://shop.spacex.com/collections/featured-products/produc...

I think it's because the dishes get warm & cats like to sit on warm things

I remember Elon saying that flight test 1 would attempt to do a soft touchdown in the water.

That's correct, there will be no catch attempt this launch. They're going to simulate a landing by attempting to do soft land it in the Gulf of Mexico. The reason is pretty straightforward: this vehicle has never flown before and a lot can go wrong. There is a lot of ground equipment including propellant tanks very close to the launch tower. If anything goes wrong hundreds of tons of metal + propellant is going to ca…

It can’t be that hard to not land it in your launch area right? Can’t they have a separate land and crash area (preferably separated by a few tens of kilometers)?

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.

Feline friends always love it when humans put out nice new warm beds for them! Certainly a warm heated spot in the cold could serve no higher purpose :): https://www.smithsonianmag.com/smart-news/outdoor-cats-are-u...

> the American Veterinary Medical Association recommends keeping cats indoors to avoid dangers associated with diseases, parasites, cars, attacks from other animals, poisons and extreme weather

Now it’s not only children but cats too? I grew up in a location where cats could go anywhere they pleased (in or outside), and it’s really strange to me that some countries recommend or require them to always be inside.

It's a good question, and I don't have a great answer for you other than my understanding is that the ground space they have to work with in Boca Chica is not really that large. And there are a lot of environmental concerns (+ the chances of blowing up on landing is greater than blowing up on liftoff).

But I've heard speculation that they might build a dedicate landing tower around their Florida launch site for that reason. No idea how accurate that is though.

Sounds like they are not planning on testing the booster catch yet, I wonder what's stopping them

They haven’t launched and recovered it at all yet, have they? Presumably they want to test out to sea where it won’t blow up the only launch tower if it comes in hot.

The booster has not yet flown, no. The closest it came was a all-engines static fire (during which 2 out of 33 engines didn't fire, but it was still enough of a success to continue with the program apparently).

The falcon 9 did several "hover over water" landings in the ocean to prove out safe landing on... land, and also to alay fears that it might miss it's target and hit a population center. Even now, falcon 9 do a ballistic reentry that would hit the water, and then propulsively adjust the landing target towards land, after the engines have safely started.

Given how much larger, and how much additional fuel is onboard, it's not surprising that they're following a similar strategy this early in the program.
