Working during liftoff, shift should end before final splash though…. Which means I’ll probably be driving at that time… -

Could the Gateway modules under production construction function as the core of the next LEO station? Since Gateway won't be needed in its intended role once SLS is cancelled. And SLS will be cancelled; it's painfully obvious that it's an expensive and practically useless dead end, and prime contractor Boeing would do well to back away from all things space right now until it gets its house back in order (best done by having an engineer in charge instead of an accountant). -

Perhaps they should be using elephants or grey whales for scale? -
So, we had some kind of technical problem.

Of a sorts, through people’s posts and the resulting commentary. Some imgurians post fascinating stuff -

FWIW, I did make a doom'n'gloom post on imgur (my other haunt) and got a reasonably prompt reply from Vanamonde, of the usual "they are aware and working on it" kind. Which I knew was all I could really expect. I must admit I was skeptical, considering how long it was down for. But I'm glad it's back up. Now if they could only slay the Bad Gateway.... -

The corollary is: If your stupid plan didn't work (spin-separation of stages?) then it was, in fact, stupid. -

Looked like the RUD was after it tipped over. I couldn’t see much on my phone, but the Labpadre feed was saying they could see a tankage section still floating -

That was just freaking incredible!!!! Especially to catch it on the first try. Oh good, it looks like the vent fires are finally out. E: I'm glad I'm usually up by 4:30 for work, so I was naturally waking up before 5am to catch this. And I need to drive my kid to work for 6am anyways, then take the dog for her run ("night ops") so at best I'll have to watch the entry on my phone, instead of on the TV like the launch... -

That’s one thin I don’t like about my immediate neighborhood: too much light pollution. Couldn’t see anything, although it was reported elsewhere in the city -

F9 started with a square engine block, later changed to round. Meanwhile, Stage Zero started with a round table, with the next version at least starting with a square. The wheel of ka keeps turning… -
The future of maritime propulsion
StrandedonEarth replied to farmerben's topic in Science & Spaceflight
Hmm, yes. Here in BC, in the 90’s, the govt wanted to build some new ferries for the Vancouver Island runs, so they built three PacifiCats, dubbed “FastCats;” aluminum-hulled catamaran ferries. They were built in local shipyards, which required training the shipyard workers to weld aluminum. Naturally, they were over budget, costing some C$400M (90s $) for the three. And as it turns out, the wake (and the damage it did to nearby shorelines) was horrendous, even at the same speeds as the older ferries. So it wasn’t long until the project was cancelled, and they were eventually sold for a mere $13M. Okay, my memory was a little spotty. Here’s the Wikilink to fill in the blanks: https://en.m.wikipedia.org/wiki/PacifiCat-class_ferry -

Made by Thales-Alenia, IIRC? Given their experience with orbital modules (ISS modules and ninjaturtle logistics modules) they really need to move towards a more mass production model to get costs down and production up. Then all these plans for orbital and surface spacehabs can pick up speed and cut costs
