Science Space Exploration megathread - Page 118

**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.

Wait, what?

I sure hope this goes well. This is definitely one of the more important things SpaceX has launched so far.

**DaFace** · 04-18-2018, 04:52 PM

Looks like a beautiful day to watch a rocket launch.

**DaFace** · 04-18-2018, 05:01 PM

Feels like it's been forever since we've actually had a landing to watch. All looks good thus far.

Bewbies · 04-18-2018, 05:07 PM

It will never get old watching rockets land. So crazy.

Molitoth · 04-18-2018, 05:17 PM

Doh, did I miss something?

Molitoth · 04-18-2018, 05:20 PM

weee, just watched the replay on youtube of the drone landing, but do not see any status on catching the fairing.

Launch and landing is done, but the webcast is still up if you want to watch. You can rewind for those parts and then go back to live to watch the second burn and deploy here in a bit.

They're still having a lot of trouble figuring that part out. They did have chutes on one of the fairing halves but no boat to try and catch it.

**DaFace** · 04-18-2018, 05:30 PM

While we're waiting for the sat deploy, I went ahead and updated the OP. Bangabandhu-1 isn't all that notable in terms of the payload, but it'll be the first launch of the "Block 5" version of the rocket. In theory, the booster will be capable of being reused up to 10 times without refurbishment. I'll be curious to see (assuming it works) if they consider giving the boosters names in the future since we'll see a single booster putting in a lot of work.

**DaFace** · 04-18-2018, 05:44 PM

All looks good. Still need to hear from NASA that they've got a good signal, but for now, we can breathe easier.

**DaFace** · 04-18-2018, 05:58 PM

Solar arrays deployed. Now TESS just has to move itself into its proper orbit over the next couple months. Total mission success on the SpaceX side!

Hydrae · 04-18-2018, 06:19 PM

That was pretty awesome. Love seeing a private firm launching FOR NASA. I have been a proponent of privatizing space since the Apollo program died.

Yep. I've slowly become more and more against SLS. NASA needs to get out of the launch vehicle game and focus on doing great science instead. Once Blue Origin gets New Glenn up and running, they'll have multiple options for providers to do just about any launch they could want.
