Science Space Exploration megathread - Page 353

**DaFace** · 07:17 AM

Since a number of cool things are happening in space exploration these days, we'll widen the scope of this thread a smidge. Conversation about all things space exploration are welcome, whether it be from NASA, SpaceX, ULA, Blue Origin, or anyone else. Chances are most of the discussion will still be about SpaceX since they love to make things public and fun, but nothing's off limits. I'll eventually get around to modifying the OP to include resources for other companies too, but in the meantime, feel free to post any cool stuff you run across.

Space discussions tend to get a little bogged down in jargon, so here's a list of terms you might encounter. (Others, please let me know of others that should be added.)

ASDS - Autonomous Spaceport Droneship - The "barges" that they sometimes land rockets on.
Dragon - The cone-shaped capsule that sits at the top of the rocket for ISS-bound launches that holds the cargo (or, in the future, humans).
F9 - Falcon 9, the name of the rocket itself.
FH - Falcon Heavy, the three-booster version.
GTO - Geosynchronous Transfer Orbit, a type of orbit that will eventually result in the satellite orbiting the earth as it turns so that it seems to be in the same spot from the ground (such as DirecTV or Dish satellites). These types of launches are particularly challenging because they require a lot of power to get them into the right orbit, leaving very little fuel left for landing.
HIF - Horizontal Integration Facility - the building near the launch pad where they put all of the pieces of the rocket together before rolling it out to the pad.
ISS - The International Space Station
JRTI - Just Read The Instructions, the name of the "barge" that they land on for west-coast launches.
LEO - Low Earth Orbit, a fairly low orbit shared by many satellites and ISS. These launches usually require less power to achieve the proper orbit, so the first stage can often be landed back on land rather than on a drone ship.
LZ1 - Landing Zone 1, basically a big open slab of concrete at Cape Canaveral where the first stage will attempt to land (for some launches).
NET - No Earlier Than, basically the date they're hoping to launch, but rocket launches have a tendency of getting delayed.
OCISLY - Of Course I Still Love You, the name of the "barge" that they land on for east-coast launches.
RTLS - Return to Landing Site, a mission where the first stage comes back and lands at LZ1.
Starship - SpaceX's next-generation rocket (and spacecraft) that will hopefully one day take us to Mars. Starship is the "second stage" that will carry cargo or people, but also refers to the whole system. (It's confusing, but think of it like the Space Shuttle, which was both the shuttle itself and the entire launch system.)
Super Heavy - The giant booster that will carry Starship to space.

RUD!!!

**DaFace** · 11-18-2023, 07:08 AM

Not losing any engines is the huge thing to me. Crazy.

Yeah that was great to see. Looks like they activated the FTS on SH? Either way, it did its job.

Go Starship!!

**Donger** · 11-18-2023, 07:11 AM

Starship MECO?

**DaFace** · 11-18-2023, 07:13 AM

Schrodinger's Starship

Damn. FTS on Starship.

But wow, what a launch!!

**DaFace** · 11-18-2023, 07:16 AM

Well bummer wonder what happened at the end. It looked like a cutoff to me rather than an explosion first, but I guess we'll see when they crunch the numbers.

Still, that's a pretty big success. Hopefully the pad is in better shape this time.

I woke up at 6:59. Perfect time.

**DaFace** · 11-18-2023, 07:22 AM

Watching the replay, I'm betting they started running low on fuel, lost some engines, and then the FTS triggered as it started to go off course.

You're talking about Starship? What replay are you watching?

**Donger** · 11-18-2023, 07:26 AM

Watching the MECO(s) of SH's engines in sequence was one of the coolest things I've seen.

Yeah, second stage. You see a poof, then the engines are dimmer, then a little time, then boom.

You watching the Twitter/X feed? I don't see a way to "rewind" that stupid shit. Wish they'd go back to YouTube.

Try Everyday Astronaut. He mirrors the SpaceX stream, so you can rewind and find it.
