Science Space Exploration megathread - Page 54

**DaFace** · 03:36 PM

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.

Glossary

Spoiler!

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.

Whatever happened - it was really weird. Oh, and fuel for the conspiracy theorists:

It's just an illustration of the concept, but here's the plan for Mars.

Elon's talk is supposedly being broadcast here at 1:30pm CT.

Will watch tonight, didn't get a chance today.

Start of the talk is ~20 minutes in...

After reviewing footage of the explosion, WaPo reports that SpaceX noticed an "odd shadow, then a white spot" on the roof of a nearby building owned by United Launch Alliance, an old-school rocket-launching company that competes with SpaceX on military contracts. The building has a clear line of sight to the launchpad where SpaceX's rocket exploded, WaPo notes.

Let the conspiracy theories begin!

Stop this shit. It's very likely that they've got a root cause analysis tree for realized risks that has "sabotage" as one of its branches. As all the other possible root causes get crossed off the list, you've got to take a serious look at it at some point.

I HIGHLY doubt this is sabotage.

Money to anyone who asks him why Andy Reid is such a sh*t play-caller when the Chiefs have the lead.

I would but I got banned for saying the play-by-play girl was hot.

AMA has started. Slow answers so far: https://www.reddit.com/r/spacex/comm...ut_becoming_a/

They've got a long way to go, but I think I'd take a vacation to Florida to try and watch that thing launch.
