Science Space Exploration megathread - Page 51

**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.

NASA says SpaceX was conducting a test firing of its unmanned rocket when the blast occurred Thursday morning. pic.twitter.com/Bc7kNiq6E0

Well, shit. Though I doubt there will be as thorough of an investigation since it was a test fire (which is meant to identify issues), chances are that did a ton of damage to the pad that's gonna take forever to fix.

Loss of payload...ouch.

Two lost payloads in 1.5 years isn't going to help opinions of their reliability.

**DaFace** · 09-01-2016, 08:40 AM

It SOUNDS like it may have been an issue with the ground equipment and not the rocket (not confirmed by official sources). That's not necessarily any better, but it's interesting if so.

**Donger** · 09-01-2016, 09:02 AM

I thought the satellite wasn't onboard?

Hydrae · 09-01-2016, 09:05 AM

It seems odd that they would be test firing it with the payload onboard.

I wouldn't have thought it would be either, but apparently it was.

**DaFace** · 09-01-2016, 09:07 AM

Sadly, I've removed the "next launch" info from the OP. It'll probably be a while before there's anything to put in there.

Tight schedule. Taking the rocket back down and performing the mounting, putting it back up, two days away from launch while still checking all the systems just wasn't feasible.

Lesson learned. At a cost of $200m.
