Science Space Exploration megathread - Page 176

**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.

Sorry. I probably should have been clear why I thought this was significant too.

The F9 booster for Starlink 7 has already flown 4 times. 2 paid and 2 Starlink missions. They could easily choose to make it expendable as it has already been more than paid for. Instead they are accepting a significant delay for a date sensitive series of missions. To meet their agreement with the FCC they need to have ~6000 satellites flying in 4 years. That's 100+ launches in 48 months, or 2 launches per month, not including their launch schedule for other customers. Currently they are planning 3 Starlink launches and a GPS 3 launch for the Air Force in June.

The next few years are going to be INSANE if they can actually meet that launch cadence. SpaceX changed the landscape for launches with it's reusable platform, and we haven't even seen the half of it yet.

Seriously. Over the next 4 years a private company is launching orbital rockets twice a month to blanket the earth with a constellation of 12,000 satellites. That is truly the stuff of science fiction. While I am super excited for DM2 and taking the day off to watch/celebrate, I think that achievement pales in comparison to launching 6000 satellites in 4 years.

Starfleet Command actually

There are also plenty of contractor jobs with the Space Force.

I ****ing hate politics being injected into science.

NASA's head of human spaceflight, Doug Loverro, has abruptly resigned — just one week before a historic test flight to send astronauts up in a new space capsule developed by SpaceX.https://t.co/axtNyKIBmR

I guess we'll see how it plays out, but I suspect we may have to get used to weather-related scrubs on manned launches. This is a lot of stuff that has to be right...
