Science Space Exploration megathread - Page 171

**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

Spoiler!

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.

Man...the pucker factor is going to be through the roof on that launch.

YES!!!! I can't wait. And sure, pucker factor high, but how many successful Falcon 9 launches have there been, and when was the last failure? And, they've got a (once) proven escape system, too!

**Donger** · 03-10-2020, 06:24 PM

Rockets from the Falcon 9 family have been launched 85 times over 10 years, resulting in 83 full mission successes (97.6%), one partial success (CRS-1 delivered its cargo to the ISS, but a secondary payload was stranded in a lower-than-planned orbit), and one failure (the CRS-7 spacecraft was lost in flight).

So, only one real failure.

Two if you count AMOS-6, which blew up on the pad. But yeah, they've launched a ton since then with no issues. Hopefully that's a good sign that all of the kinks are now worked out.

EDIT: I count 57 successful launches in a row, but I could be off by a couple.

**Donger** · 03-10-2020, 06:28 PM

Ugh:

If U.S. airlines had the same failure rate as the now-retired space shuttles, there’d be 272 fatal crashes a day.

It's not a launch if it doesn't leave the pad.

CAPE CANAVERAL, Fla. — The private spaceflight company SpaceX will launch 60 new Starlink satellites to join its ever-growing broadband internet megaconstellation Sunday (March 15) and you can watch it live online.

A SpaceX Falcon 9 rocket will launch the Starlink mission from Pad 39A at NASA's Kennedy Space Center in Florida. Liftoff is scheduled for no earlier than 9:22 a.m. EST (1322 GMT).

This is SpaceX's sixth launch of the year and the sixth Starlink launch to date. The mission will star a veteran Falcon 9 rocket that will do what no other Falcon has done before: launch and land five times. The booster, dubbed B1048.5, previously launched a bevy of satellites including part of the Iridium NEXT constellations, an Israeli lunar lander a communications satellites for Argentina and Indonesia, and a previous Starlink mission.

This is a major milestone for SpaceX. The upgraded version of their workhorse was introduced in 2018, launching the first communications satellite for Bangladesh. Company founder and CEO, Elon Musk said that the souped up booster would be able to fly ten times with little refurbishment in between. Sunday's flight marks the first time a Falcon has reached the halfway point.

They need to step this shit up. We need a new planet soon. This one is infected.

You should see the food for when the time comes. All that will be left to eat are these dehydrated vegetable chips. Oh and it will be 1 billion dollars for a space ticket.

**DaFace** · 03-15-2020, 07:08 AM

Bump for this morning's launch in case anyone's interested. Coming up in ~15.

allen_kcCard · 03-15-2020, 07:11 AM

Feed up, ~11 minutes

**DaFace** · 03-15-2020, 07:23 AM

Whoa - abort. It's been a while for one of those.

allen_kcCard · 03-15-2020, 07:23 AM

Abort right before liftoff, not sure why yet.

allen_kcCard · 03-15-2020, 07:25 AM

No launch today then.
