Science Space Exploration megathread - Page 303

**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.

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.

I suppose it's remotely possible that they could try and keep SpaceX from spending NASA money on it, but it seems crazy unlikely they could make them stop work entirely since the overall goal is Mars.

SpaceX has been working on SS for years. HLS is just a side project. Bezos would be laughed out of court. It's worth noting that SpaceX is not an interested party in this case, the court has zero jurisdiction over anything not HLS. It's also worth noting that this is a "voluntary" stay by NASA, not a court order.

SpaceX also has multiple other contracts with NASA, including the development and testing of on-oribit fuel transfer. SpaceX has so many other things going on right now to get SS moving, that this will likely have zero impact on their part of HLS. It will however make great headlines for NASA to say "we were delayed by frivolous lawsuits" when Artmis doesn't launch in '24.

It would also be funny as shit if SS has made orbit before the hearing.

The money they got from NASA was for milestones achieved already. They may get another check on November 1 for more milestones achieved. lol

This makes sense...

Possibly the most surprising thing (for me anyway), is the complete silence from Elon. It feels like he goaded BO into this with his Twitter trolling, and is now sitting back and watching.

Gonna be hard for me to give any shits about what BO is up to until they stop emulating the shape of their rocket.

Emulating the shape of their rocket?

Pretty funny that the cargo in the capsule are "lunar landing material" or whatever she said.

That thing wobbles. The whole landing looks precarious.

Astra had another attempt yesterday, but it failed in amusing fashion.

Reviewing flight data and video, two things are very clear - 1) An engine shut down right after launch 2) Everything that happened next made me incredibly proud of our team. Space may be hard, but like this rocket, we are not giving up. #AdAstra pic.twitter.com/2g3n812EaW

Remarkably, it managed to right itself and actually made it through part of the mission, but they triggered the FTS system once it was unrecoverable.

Still more exciting than a flying penis launch though.
