Science Space Exploration megathread - Page 108

**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.

There's probably an element of technology allowing it too. I'm sure there are some pretty sophisticated computers running all of this stuff that might not be possible 10+ years ago.

Oh I know I was over simplifying it, but until Musk ULA basically had a monopoly on the rocket game and had no reason to update their business model. Why innovate to lower prices when people had to pay 300 million for a launch.

**DaFace** · 02-06-2018, 04:58 PM

We're gonna have some great shots of this thing.

Ohh my god @ChrisG_NSF & @NASASpaceflight! Remote number one from Falcon Heavy! pic.twitter.com/aj4ly8Cr5r

Uh, did something just happen? It looked like something hit the rocket

edit: I think it was an optical illusion based on the video skipping and suddenly a reflection is on the rocket.

**DaFace** · 02-06-2018, 05:49 PM

Press conference coming up soon if anyone is interested.

Because the Pentium chip had a floating point problem and the rockets would miss and crash.

Do we know if the main booster landed successfully yet?

It successfully hit the water at 300 mph. 2 of 3 rockets didn't light.

Kiimo · 02-06-2018, 06:26 PM

Geez is it totally destroyed?

Chitownchiefsfan · 02-06-2018, 06:38 PM

Anyone watching the star man feed? There was a few minutes where the lights died then the feed went down. Back up now though. Anyone know how long that feed is supposed to last?

The booster? Yeah, it's in a million tiny pieces. Sounds like the drone ship was damaged as well, but not beyond repair or anything.

They weren't going to reuse any of the three boosters, so at least they still got good data from it and can learn for the future.

**DaFace** · 02-06-2018, 06:51 PM

Cool little quick recap gif.

Chitownchiefsfan · 02-06-2018, 07:14 PM

This should go without saying but never go on Twitter to see what people are saying.

People who have no idea how the space industry works ( I barely have a grasp on any of it) bitching about there being a car in space.
