Science Space Exploration megathread - Page 24

**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

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.

Try this (and then run).

If you don't have a match (TSA will prolly take them away), watch this and be ready to tell some rocket nerds what they did wrong...

And you're going to need to stuff a lot of lox into the tank, what's on top in the pic is what you'll need. Wait to buy it on the other end, if you leave it in your luggage your shirts are going to smell in no time...

The Heavy launches are great. Three rockets strapped together. Love the night launches, the whole sky lights up with an orange glow.

Next attempt is Sunday evening.

Here's SpaceX webcast explanation of why the Feb. 25 launch was stopped 1min 40 seconds before liftoff. pic.twitter.com/6yUjBdSxKJ

Wonder why they haven't officially announced Sunday yet. Hope that holds.

As for the LOX issue, presumably they would have loaded it normally during the static fire, so I wonder if there's some reason that things aren't performing reliably the same way every time. I wouldn't think that external temperature variation would matter much, but who knows why else they would've just plain missed the mark.

GloryDayz · 02-26-2016, 03:49 PM

I also wonder how long a rocket can sit outside like that? Or will the bring it in?

They lower it down horizontally overnight at least, but I doubt they bother bringing it inside unless there's an issue with the vehicle itself that needs to be addressed. Otherwise, I can't imagine weather would have any appreciable impact on it for quite a while.

eDave · 02-26-2016, 04:27 PM

The Range Support and ER Maintenance Downtime rows are driving me crazy. I can't even.

What don't you understand about this?

You are kidding right? Trolling?

What do I not understand? Formatting. My god, why don't you know this? All rows should be of same height if the cell is less than 30 characters. If it is more than 30 character, look into reworking your cell content.

No wonder jobs get outsourced. Much cheaper labor at least understands this basic data reporting rule.

Go back to school.

I had no idea why you were cranky either. It's not like it was designed for public consumption.

Formatting? "We're talking about Formatting" In my best Allen Iverson voice.
I thought you had didn't understand why the 45th Space Wing was doing Range Support and ER Maintenance.

No new info, but tomorrow night is now confirmed:

SES and SpaceX are now targeting to launch #SES9 on Sunday, 28 February, at 6.46pm ET, with a backup date on Monday, 29 February!
