Science Space Exploration megathread - Page 110

**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.

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 just gotta thank you all for the updates on all this. It is so cool. Watching all the videos. I actually just showed the summary one DaFace posted earlier to my class.

Okay, that was one of the coolest things that I have ever seen. Wow.

I read his comment as "people who don't know how the industry works don't realize that space is big and that this isn't cluttering anything up."

Basically this. Some highlights.

- why doesn't he use the money to help fight poverty rather than a vanity project to send a car in space.

- isn't space trash already a huge problem

- look at what our tax dollars are being wasted on (it's not)

I stopped reading at that point really.

Though my fiancé made me laugh because when I told her the core crashed into the ocean she went "what about the fishies." she was joking. Mostly.

MagicHef · 02-07-2018, 12:48 PM

Musk said that SpaceX would now be focusing on developing the BFR. I hadn't even heard of the BFR until I googled it. Holy shit.

Is BFR short for Big F_cking Rocket?

Yes. Estimated payload to be five times Falcon Heavy's.

I hope there's a day where we ride these things for international flights. Anywhere on earth in like 20 minutes.

Musk has proposed just such an idea:

Here is a good read on the BFR and estimated time lines for future plans:

Whoa, I read his enormous Musk series, but somehow missed this one. Thanks!

I was just about to mention the G-loading and then read the article. I haven't seen figures on the Gs pulled on ascent and descent, but I'd guess somewhere close to 8. That might kill some people and make most lose consciousness without a G suit and training.

The article uses the G forces for ballistic missiles, which have a conspicuous lack of humans on them. Assuming the flight design would be the same for human flight seems... dumb.

I tried to reply with the arch "stop. My penis can only get so erect" but apparently I cant post pictures yet.

**Easy 6** · 02-07-2018, 06:05 PM

Havent paid as much attention to this as I should, but gotta say I was just so impressed watching the two boosters come down and land... getting a tubular shape that really only seems good for going up, with no real control surfaces, to stabilize midair and smoothly land in an upright position is nothing short of mind boggling

It almost doesnt even look real, its like CGI... AMAZING technological advance
