Space and Science BS Thread

60% humidity I’m like:

 

What can I say?

 

Sounds like the backup plan is the F9 launchable 'gen2 light'.Still incorporates the upgrades in the V2 sats even at a lower cadence. (see https://spacenews.com/spacex-adds-falcon-9-back-to-second-gen-starlink-launch-plan/)

If nothing else, it'll also be useful for the high inclination shells since Boca is launch azimuth limited.

What happened to @Fishawk ? Anyone seen him around

Kinda related, there's a SpaceX launch out of SLC 40 in a few minutes..

Edit: launch was scrubbed due to Wx. Will try afain tonight.

 

Looks like B7 is making good progress with coordinating the staggered spin primes and they’re working on the deluge system as well. I didn’t know it wasn’t ready yet. I saw what look like caissons surrounding the OLM to block exhaust and debris.

 

Fingers crossed they can recover attitude control of Capstone and get it back within autonomous capability.

 

The drooping pipe they have been installing around the bottom of the OLM is rumored to be for the water deluge. I figure we won't see a 33 engine static fire until the deluge system is complete.

What do you mean by cassions?

 

The hexagonal stacks ringing the OLM.

 

Where now?

 

‘Nother scrub for the F9 due to weather…

 

Oops, yours is a better image. Whatever those stacked piles are, I thought they were hexagonal before.

 

I didn’t know Voyager I was the first to take:

Such a cool pic. Doesn’t capture the speed at which everything is moving, though.

Here’s the un cropped pic:

Just doesn’t seem right…

 

Cool stuff:

The day I turned 18

Could use it for 3D printing either for unpressurized spaces or to encapsulate Sierra Space modules though I still think doing either underground in natural or bored caverns is a better place to put them.

 

Ah, those are part of the earthen berm that protects the GSE.

You're still going to need something on the surface for airlocks.

 

Never said you wouldn’t but what is meant by “surface” is debatable. Caverns could have ramps made of that consolidated regolith leading down to an enclosed vehicle park and on to the air lock. An abandoned starship could be sunk vertically as both multilevel access with an airlock at the top leading to a 3D printed domed vehicle park. It’s pretty’s well understood already here on earth that getting from a dirty area to a clean one is most effectively done as a staged process. We’d be much better served by shipping both content and container in as small a package as possible and the use of 3D printing and inflatables serves that purpose very well. Both boring and using existing caverns present challenges unique to the process but also come with built in advantages not to be duplicated on the surface. One could start with a suitably small crater, build the structures, then bury the entire thing. Leaving the top of an HLS or other access, instrumentation, or mind blowing view ports still exposed. Surface habitation is many inevitable bad things waiting to happen. However it’s done, we need to learn the underground lifestyle.
One of the ways dryer vents are filtered when there’s no access to the exterior is to bubble the air through a water basin that traps the lint. Passing regolith laden air through water and using the collected sediment in the 3D printing process kills 2 birds with powdered stone.
