I assume they are going to try and land this on land?  Or will they go for a water landing/hover first?

 

Land, but I'm assuming they'll do a divert like they do with RTLS Falcon 9 boosters.

 

In a divert the unpowered impact point is in the drink. If the engines fire it diverts to the landing pad, if not it takes a swim.

Will 15km be high enough to test the belly flop landing, or will it just be higher hop?

 

It'll be a full-up test of the belly flop landing - aka skydiver.

 

Subsequent flights will go higher and eventually hypersonic to test the heat shields; high angle of attack re-entry, etc.

 

Best prepare some popcorn and a brew.

Do they have a landing pad that isn't quite so close to where they've previously been doing tests? Given the high chance of a new crater in Boca Chica It scares the hell out of me that this thing could end up spiralling into one of the newly built high bays.

Like Falcon 9 landings, they'll likely use a divert maneuver. The trajectory will nudge out over the water, so if the engines don't light it goes in the drink. If they do fire it'll steer back to the pad. They also have considerable property south of the launch site full of nothing but sand & wild grass.

I assumed that, but the pad they land Falcon 9s at seem to be in the open quite a bit, I've not seen anything at the BC site that is as open as those pads.

 

Although, just looking for some aerial photos I stumbled on the below, I forget just how far the high bays are compared to the launch pads (top of the picture) so I think this helps me understand. For some reason I had it in my head that the launch pad was to the bottom right of the site.

Old photo. Looking East towords the Gulf, the red square is roughly where the landing pad and new launch table are.

    • Bluesky COO warns social media regulations could destroy competition from small startups

      By zikalify · Posted

      Bluesky COO warns social media regulations could destroy competition from small startups by Paul Hill Fears that increasing government control of social media risks regulatory capture by the biggest social media firms were raised again recently. Bluesky’s chief operating officer said in an interview that social media bans for children and tighter regulations for social media firms risk creating a world where there are only a few social media platforms run by companies with the deepest pockets. Regulations on social media firms have been very lax since they appeared for mainstream users in the 2000’s. This gave Meta, Snapchat, and Google time to build up their user bases and get entrenched, with Meta being the most successful. Now that Meta has succeeded, it has been attempting regulatory capture. By pushing for more regulations of social media, Meta hopes to make it more difficult for rivals to challenge it. For its part, it doesn’t need to worry about the cost of regulation because it has a lot of money to spend, whereas startups do not. Speaking to CNBC, Rose Wang, Bluesky’s chief operating officer, said: “I support the protection and the safety of youth, the question that we have then is at what cost, because essentially what I’m scared of is in the long term, we’re headed to a world where there’s about three to five platforms, and extreme heavy regulation of those platforms, and basically the whole compliance teams of these platforms are 10 times the size of our entire team. So, basically, we’re living in a world where it’s almost impossible for smaller entrants to come in and build healthier spaces. These platforms have led to a place where the bottom line is the thing that drives what they do... so I understand why governments have to step in and regulate, because the platforms have done nothing right.” She said that while she is not against regulation, there needs to be more channels between the small to mid-sized players and regulators to help protect them. She says that big tech players, on the other hand, “who we know are circumventing regulation,” need to be regulated. Essentially, the Bluesky position is one of nuance, rather than absolutes. While Bluesky’s proposal may preserve competition in the social media space, it still doesn’t address the massive privacy implications these age verification measures introduce, such as handing over sensitive identity documents to access age-gated content.
