How long will the "just catch the booster with grabby arms lol" meme last? A month? A year? Until they RUD a booster trying?

It's gonna replace unguided launch mount landings as the new "aspirational goal" for Super Heavy landings. At best, it'll happen in five years. At worst, it'll die like sweaty reentry.

They probably figured it's easier to pick Super Heavy out of the air than to rely on precision landing to get it back on the launch pad, which is something that Elon wants in order to boost launch frequency.

More like Super Heavy will land like a trampoline with those shock absorbers giving Super Heavy some extra room for safety incase of balance issues.

They're not going to grab it like a hand grab, but rather it will land its gridfins and park it on a soft cushion.

Who cares? They could weigh ten tons per leg and hardly put a dent in Starship's capacity.

It doesn't need to be in LEO, it needs to be at Earth-Moon L2, which means a bunch of refuelings of Starship for the initial deployment AND for any other shipments of water to refill the depot. If you're refueling Starships enough to get them to L2 you might as well top off the tanks the rest of the way so Starship can haul the payload to Mars itself. The interplanetary tug concept ONLY works with lunar ISRU since Starship is so much cheaper for hauling propellant up the well.

Giant swinging arms can fail. Three inch thick fixed steel pipes are very unlikely to fail. Just throw mass at the legs until they're unbreakable.

Try being British. I want my country to build a super heavy lifter that can transport colony material to the moon. Also I wish we could fulfill the dream we had in the 50s of having home-built nuclear reactors power our country, maybe even design NTRs for super heavy vehicles.
But Black Arrow, HOTOL and Skylon tells me that the government would screw over any effort to be a leading country in science and technology if it meant a short-term political gains.
