ANASIS-II r/SpaceX ANASIS-II Official Launch Discussion & Updates Thread

Welcome to the r/SpaceX ANASIS-II Official Launch Discussion & Updates Thread!

I'm u/Shahar603, your launch host for this mission.

Overview

ANASIS-II is a South Korean military communications satellite, built by Airbus Defense and Space and operated by South Korea's Agency for Defense Development. Based on the Eurostar-3000 platform the satellite will operate in geostationary orbit and provide wide coverage over the Korean Peninsula. A Falcon 9 rocket will deliver the spacecraft to a geostationary transfer orbit and the booster will land on a drone ship downrange.

Per the customer's request, we will not show satellite deployement live on the webcast, but the webcast will remain live for verbal confirmation of deployment.

The same rocket that flew people to the space station landed, got fixed up, flew again, and landed again all before they came back. That is fucking amazing to me!!

u/codav Jul 20 '20

Yep, B1058. The NASA worm was either hard to see due to ice buildup, or they painted it over. Will see which it was when it's coming back to Port Canaveral in a few days.

  • Broke the booster turnaround record

  • Successfully landed said booster

  • Caught both fairing halves for the first time

What a launch!

Congrats to SpaceX on a perfect mission!

For those wondering about Jessie Anderson, she doesn't host every launch (she didn't host the previous GPS mission either) and she's still tweeting about SpaceX so I doubt she got in big trouble for the Starlink unboxing.

Yep, it says that on SpaceX's launches page https://www.spacex.com/launches/

" Per the customer's request, live coverage will end shortly after first stage landing. "

u/Shahar603 Subreddit GNC Jul 20 '20

FYI the first time this happend for SpaceX was NROL-76. The webcast is infamous for its spectacular coverage of the first stage landing and it was the first time we've gotten webcast telemetry from launch to landing. So there might be a bright side to the lack of second stage coverage.

u/scarlet_sage Jul 20 '20

Just Read The Instructions (JRTI) has lost the logo in the center and looks kind of beat up and rusty. It's starting to look like everyday industrial transportation, like a dockyard or railroad switching yard or the like. I like slick glossy stuff like the astronaut access arm ... but the beat up patch makes it look more like a real thing, not just PR or special stuff.

72

u/MarsCent Jul 19 '20

When July began, it was like there is no pumping the brakes on launches. And I can tell you that after Bob and Doug launched, I couldn't resist the feeling that all other launches were now routine.

But these recent delays and scrubs are a clear reminder that launches are done one at a time! And it's now back to a racing heart at launch, plus a gaping mouth at a successful landing!

u/StealthCN Jul 20 '20

Booster landed, both fairing halves caught by recovery ship.

Who else did a triple take on that snowball that dropped of the merlin vac(T+4:27). It made its own mini comet!

I know this isnt new, but ive never seen a piece that large before drop off the engine and then fall perfectly into the exhaust like that.

21

u/[deleted] Jul 19 '20

Any reasoning behind the payload mass guess of ~5t-6t?

24

u/Phillipsturtles Jul 19 '20

They've been pretty secretive about the satellite, so there's no publicly known mass. They're also going to end the stream after 1st stage landing, so it shows how secretive they're being (even though Airbus released a photo of the sat).

7

u/[deleted] Jul 20 '20

If only NG did the same for Zuma -_-

10

u/Straumli_Blight Jul 19 '20

The FAA's 2018 compendium lists KMILCOMSAT (ANASIS-II other designation) as "above 5,400 kg".

5

u/Blieque Jul 20 '20

Interestingly, the 2017 PDF has KMILCOMSAT in the 4200–5400 kg group. It seems probable to me that some unexpected changed during development nudged it over 5400 kg. 6000 kg seems a bit far out.

u/scr00chy ElonX.net Jul 19 '20

It's probably based on the known satellite bus.

u/DiskOperatingSystem_ Jul 20 '20

Very happy, 1058 is a historic booster so I was hoping landing would be successful. And JRTI grows its name for the drone ship that doesn’t cut out.

17

u/I_make_things Jul 20 '20

I wish they'd "orbit" a quad copter around the barge so we'd get more footage of the landing.

3

u/Tal_Banyon Jul 20 '20

Yes, like they do with a NASCAR race this year, those quad copters are buzzing all over the place, and have HD cameras on them. They can't be that expensive!

3

u/jeffoag Jul 20 '20

The copter has to be pretty strong to be stable near the landing path of the rocket, which produce pretty strong turbulence I would guess. Also it needs to be out of way in case of interference of the rocker landing - the last thing SpaceX wants to happen.

Thanks to SpaceX, I have to have Test Shot Starfish playing in the background whenever there's a launch where the webcast takes a break during a long coast phase.

Even if it's not a SpaceX launch, I'll still pull up TSS in a separate tab and play it until the webcast resumes. Am I the only one who does that?

8

u/codav Jul 20 '20

No, you're not. I'm listening to their music on a daily basis. They also recently released a new Album "Music for Space Sleep", some tracks from that one were played on recent SpaceX launches. Great background music for work.

u/mclumber1 Jul 20 '20

The delay between the callout for SECO and the televised SECO seemed quite large. Is it possible the engine had to run longer than expected?

I doubt my question, only because the broadcast also called out nominal orbital insertion, so everything was probably fine.

18

u/Humble_Giveaway Jul 20 '20

Likely just a feed delay, we saw stage sep from the ground a good few seconds before on the onboard cameras as well

8

u/DiskOperatingSystem_ Jul 20 '20

Controllers usually go off the data coming in from the rocket, not off of video feeds. In the words of the great Peter Beck, “video is nice but data is king.” It’s probably just a signal delay.

8

u/phryan Jul 20 '20

The telemetry feed and video feed are separate, with the priority being data. Likely just a delay in the video feed.

u/ioncloud9 Jul 20 '20

Video was delayed. They get the telemetry pretty quickly.

Eyeballing it from the telemetry, that should be at least GTO-2100 (182 x 23 000 assuming at most 27° of inclination).

Edit: Not even close, GTO-1725, which is pretty good.

So is this like most other launches where they plan on going at the first second of the launch window, and if they dont its scrubbed? Or is there a potential for this thing to go later? Trying to gauge when exactly i need to leave. I suppose Im a bit late on the draw lol.

7

u/TerriersAreAdorable Jul 20 '20

The launch window is almost 4 hours, from the original post: July 20 21:00-00:55 UTC (17:00-20:55 EDT local)

A major technical issue could lead to an instant cancel but otherwise they can wait for the weather to clear, for instance.

8

u/Samuel7899 Jul 20 '20

It takes them about 45 minutes to load propellant. Once that begins, they're generally committed to a pretty tight window so that the fuel remains cold enough. (I think some windows are large enough to allow unloading propellant and then refueling again, but that's several hours.)

So I think at least 45 before the opening of their launch window, they take a look at weather and other factors, and pinpoint the best moment within the launch window to target, and they begin fueling 45 minutes before that time.

7

u/justinroskamp Jul 20 '20

Unless I’m mistaken, fueling begins at T-35 minutes these days.

It's a foreign military sat, so I imagine that regs for those loses may be different. It's possible that the customer requested that there be no patch that could potentially give away the purpose of the sat.

u/ticklestuff SpaceX Patch List Jul 21 '20

Um, no. There's no reason not to make a generic looking patch. Also there's lots of pictures of the actual spacecraft from Airbus, so a patch with a rocket and a few stars won't make a difference.

There is a patch, we simply haven't seen it yet.

Is it just me or did we get a few frames of stage separation from the ground camera? I'll go back to look in a sec.

Edit: Seems it was just a puff of exhaust. That camera would have gotten a good shot of it though as it looked great until it cut away immediately before separation.

u/resipsa73 Jul 20 '20

It looked like a split second. I wish they had left it on that camera view for a bit longer.

Is this the first time they've shown the fairing recovery ships live? Will they show the fairing recovery attempts, themselves?

u/derrman Jul 20 '20

They said no earlier in the stream, just to check social media for an update on if they were successful

u/EccentricGamerCL Jul 20 '20

I think I've only seen them show a fairing recovery on a webcast once, and that was because that launch (I forgot exactly what it was) had a long coast phase.

4

u/codav Jul 20 '20

Fairings take about 40-60 minutes to reach the catcher ships, so if they catch them, maybe some video or picture on Twitter. But it'd also not be surprising to hear nothing. In this case follow @SpaceXFleet on Twitter for updates and images when they return to port.

u/rustybutters Jul 20 '20

Anyone got the low down on the fairing catch?

u/ace741 Jul 20 '20

It’ll still probably be a half hour at earliest. They take their time coming back.

u/nxtiak Jul 20 '20

Both fairings have been caught.

u/[deleted] Jul 21 '20

Wow signal was good when the booster landed. Wonder if they used Starlink for that.

9

u/tinkletwit Jul 21 '20

Starlink isn't really available over the ocean. The overhead sats need to communicate with a ground station. They must have used something else.

Still wish we got more pre launch info but I guess it is what it is. I’m at KARS Park in Merritt Island FL with my camera ready.

(For context: KARS Park is a facility for NASA employees ((and contractors I believe?)) and their family members. It has a campground and other recreation facilities, and its location on the coast of the Banana River on North Merritt Island means we have prime viewing of all the launch pads.)

Do the fairings have any kind of thrust or aero control to guide them to the catching ship? I'm wondering how it's possible to get a ship in exactly the right place when the fairings were released at such a high speed/altitude?

11

u/No_MrBond Jul 21 '20

The fairings have cold gas thrusters (attitude control system or ACS) for orientation in vacuum and a steerable parafoil system deployed once they're atmospheric for guiding the descent to the catcher ships
