Discussion thread for Starlink v1.0 Launch 18, AKA RF Mission 1-1.
NSF Threads for Starlink v1.0 Launch 18: Discussion (https://forum.nasaspaceflight.com/index.php?topic=52617.0)
NSF Articles for Starlink v1.0 Launch 18:
SpaceX launches first of twin Starlink missions, 45th Space Wing’s busy year continues (https://www.nasaspaceflight.com/2021/02/spacex-twin-starlink-45th-busy-year/)
Successful launch February 4, 2021 at 01:19 am (0619 UTC) on Falcon 9 (booster 1060.5) from CCSFS SLC-40. Successful ASDS landing on Of Course I Still Love You towed by tugboat Lauren Foss. Fairings successfully recovered from the water by Ms Tree and Ms Chief.
Payload: A batch of 60 Starlink satellites. Expected deployment orbit of approximately 250x291 km.
SpaceX is targeting Thursday, Feburary 4 for launch of 60 Starlink satellites from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The instantaneous window is at 1:19 a.m. EST, or 6:19 UTC.
The Falcon 9 first stage rocket booster supporting this mission previously flew on four missions: the launches of GPS III Space Vehicle 03 and Turksat 5A and two Starlink missions. Following stage separation, SpaceX will land Falcon 9’s first stage on the “Of Course I Still Love You” droneship, which will be located in the Atlantic Ocean. One half of Falcon 9’s fairing previously flew on the SAOCOM-1B mission, and the other previously flew in support of the GPS III Space Vehicle 03 mission.

L2 SpaceX:
https://forum.nasaspaceflight.com/index.php?board=60.0 (https://forum.nasaspaceflight.com/index.php?board=60.0)
From a previous mission's Press Kit:
Each Starlink satellite weights approximately 260 kg and features a compact, flat-panel design that minimizes volume, allowing for a dense launch stack to take full advantage of Falcon 9’s launch capabilities. With four powerful phased array and two parabolic antennas on each satellite ... At end of their life cycle, the satellites will utilize their on-board propulsion system to deorbit over the course of a few months. In the unlikely event their propulsion system becomes inoperable, the satellites will burn up in Earth’s atmosphere within 1-5 years, significantly less than the hundreds or thousands of years required at higher altitudes. Further, Starlink components are designed for full demisability.
Starlink is targeting service in the Northern U.S. and Canada in 2020, rapidly expanding to near global coverage of the populated world by 2021. Additional information on the system can be found at starlink.com.

What’s different about the name and why? ???
-
What’s different about the name and why? ???
Not sure, just going by what’s on the paperwork.
Usually SpaceX uses Mission 1xxx as a temporary placeholder, but this time they’ve changed things up with a new naming scheme. It could be an indication that something is different with the satellites.
We’ll see what SpaceX does closer to the launch date and we get more details. If there is no functional difference, it’ll prob just go back to the usual nomenclature.
-
Could this be a new 1.1 satellite design?
-
Could this be a new 1.1 satellite design?
It’s possible, but there are other missions planned such as 2-1, 3-1, etc. so can’t just go by the name.
Another theory is that they will go to different orbital shells, like the new polar orbits.

To point out the obvious, maybe this has something to do with the laser interlinks.
Could be both, laser interlinks and polar orbits. The laser interlinks would be almost required for the polar satellites, ground stations in the far north and south latitudes would be prohibitively expensive.
-
On closer inspection, the ASDS locations are the same as the other Starlink launches. That rules out polar orbits.
So most likely just a new nomenclature, or maybe some modifications (like lasers).

Musk’s dislike of acronyms is well known.
It’s not going to lessen if the addition of laser cross-links is indicated by the acronym for “Radio Frequency”.
I’ve heard things that suggest that laser cross-links are not on the upcoming satellites.
-
Reflight? To replenish birds that have deorbited or malfunctioned?

Related to "Starlink RF test engineers"?
https://www.indeed.com/m/viewjob?jk=0d536252a68fc1c7&from=serp
Mark Handley speaks of "Starlink's RF links" via ground stations as the alternative to laser inter-satellite links (ISL):
https://discovery.ucl.ac.uk/id/eprint/10090242/1/hotnets-ucl.pdf
Guess: "Starlink RF" = Starlink V1.1 (next development step, still using ground radio links), with Starlink V2.0 to come as e. g. "Starlink ISL" with lasers.

Ben Cooper lists two Starlink launches in January and at least one in February. I'm not sure if the second launch in January is supposed to be L17 or RF 1-1.
A Falcon 9 will launch the seventeenth batch of Starlink internet satellites
on January TBD. A Falcon 9 will launch the eighteenth Starlink batch on January TBD. And a
Falcon 9 will launch the nineteenth Starlink batch on February TBD.

Could the “R” be for Rural and indicate the launch is subsidized by the FCC grant (“F”=“Funded”)? I can imagine SpaceX might want funded flights to be tracked separately. I don’t know if the timing works or not.
-

No. All of the satellites pass over the same locations. They don't have money from the FCC yet.
-
Thanks. When is funding supposed to start?
-
They have to fill out another more detailed application form and have it approved, then I think the first year's funding is available, which should be 10% of the total. Should be in the first half of the year? The FCC money is for building out the whole network and providing service to end users, not specifically for launching satellites.

NET 1 February could be taken logically as = to NET February. See:
Ben Cooper's Launch Photography launch viewing page (http://www.launchphotography.com/Delta_4_Atlas_5_Falcon_9_Launch_Viewing.html), updated January 20; my bold:
FALCON 9
The next SpaceX Falcon 9 rocket from Cape Canaveral will launch the Transporter-1 small-satellite rideshare mission on January 22 at 9:24am EST. The launch window stretches 58 minutes to 10:22am EST. Then, a Falcon 9 from pad 39A will launch the eighteenth Starlink batch on January 27, around 8 or 8:30am EST. And a Falcon 9 will launch the nineteenth Starlink batch on February TBA. Other upcoming launches include Starlink missions in February TBA.
If SpaceX continues to alternate launches from LC-39A and SLC-40, then this launch would be from SLC-40, following tomorrow's scheduled Transporter-1 launch. We'll see how quick a turn-around that SpaceX can do!
We'll also see how many Starlink flights will go before the Crew-2 and SXM-8 launches this spring!
-
NET 1 February could be taken logically as = to NET February. See:
Michael doesn't use that notation. If it were just NET February, he would have it at the end of month (in the list at https://nextspaceflight.com/launches/ (https://nextspaceflight.com/launches/)) and it would say "NET February, 2021". In fact that's what he has for L19, L20, and L21.
Edit: Added clarification.
-
If SpaceX continues to alternate launches from LC-39A and SLC-40, then this launch would be from SLC-40, following tomorrow's scheduled Transporter-1 launch. We'll see how quick a turn-around that SpaceX can do!
9 day turnaround on SLC-40 has been done before several times. The primary constraint I see would be ASDS availability. The new 24 hour dock unloading turnaround will help a lot, but transit time is still an issue.
-
The most likely booster for this launch based on availability is B1059.6, with a 44 day turnaround from Dec 19 - Feb 01.
Alternatively B1063.2 if it is not on the west coast, with a 71 day turnaround from Nov21 - Feb 01.
Those are the only two boosters available in that timeframe.

-
https://twitter.com/elonmusk/status/1353574169288396800
So no laser interlinks, which makes it doubtful that there are enough major differences to warrant a v1.1 at this time.
Possible, but unlikely. Hopefully more details as we approach launch date.

I'm pretty sure 63.2 is reserved for NASA's DART mission.

Not exclusively, in the same way B1058 was slated to fly CRS-21 for months, but still had other payloads in between.
Nonetheless, the point is that there are only two possibilities, with B1059.6 the most likely.

Cross-post; probable delay into beyond February 4; my bold:
http://www.launchphotography.com/Launch_Viewing_Guide.html
FALCON 9
The next SpaceX Falcon 9 rocket from Cape Canaveral will launch the eighteenth Starlink batch from pad 39A on February at ~6am EST. Launch times for Starlink launches get around 20-22 miutes earlier each day. Then, a Falcon 9 will launch the nineteenth Starlink batch from pad 40 on February 4 earliest at 1:19am EST. A Falcon 9 will launch the twentieth Starlink batch on February TBA. Upcoming launches include more Starlink missions on February TBA.
I think Ben is saying:
Because of the delay of Starlink v1.0 Flight 17 beyond February 1, Starlink v1.0 Flight 18 will also be delayed.
Each day's delay moves the launch time 20-22 minutes earlier.
February 4: 06:19 UTC,
February 5: ~06:00 UTC,
February 6: ~05:40 UTC, rounding up to ~06:00 UTC,
and so on.
We shall see.

There is no delay to this launch yet. SpaceX can launch 2 F9s on the same day within a few hours.
The 6am EST launch time indicates a Feb 3 launch for Starlink v1.0 L17.
That is different from the 0619 UTC launch for Starlink v1.0 L18 a day later.
You had put a 0600 UTC time for this launch, which doesn’t make sense.

One half of Falcon 9’s fairing previously flew on the SAOCOM-1B mission, and the other previously flew in support of the GPS III Space Vehicle 03 mission.
You can watch a live webcast of this mission, which will begin about 15 minutes prior to liftoff, by clicking the image above.
I think it's the first time when SpaceX doesn't give any mission number here (e.g. the previous mission was called "seventeenth Starlink mission").
Webcast:
https://www.youtube.com/watch?v=fe6HBw1y6bA
EDIT: And surprise, from the description it looks like it's booster 1060.5, not 1059.6.
-
If it is B1060.5, it would be a record turnaround of 27 days, 4 hours, and 4 minutes from the launch of Turksat 5A on January 8.
So basically SpaceX is now able to fly the same booster twice in a month.

They keep this up and they're going to need a bigger more boats. Also, that video from the barge was solid the whole way through. Did they just improve their antenna stabilization or are they using Starlink to relay video and data from the barge?
The need for more ASDS has been discussed repeatedly (search for A Shortfall of Gravitas).
The video is actually usually pretty good. The LOS on the landing is due to the intense vibration causing temporary signal lock failure.

Yes, they record the landings locally, but they don't always share the photos and videos afterwards (especially these days since it's pretty routine).

Forgive me if I missed it but I don't recall them ever giving us S1 telemetry all the way to the drone ship. ISTR we've had some in the past, but I don't think I've seen it all the way down. Seeing it tick by is so much more visceral than the excellent plots that are produced.
Staged at about 7900 km/h and 67 km
Topped out at 7100 km/h and 115km.
Velocity drifted up to 8066 km/h at entry burn.
Entry burn dropped that to 5750 km/h.
Only picked up 6 km/h before the reorientation took hold.
And bled enormous velocity all the way to the landing burn.
That was fascinating the watch.

Ms. Tree looks to have finished fairing recovery work at the Starlink LZ and appears to be en-route to Port Canaveral.
If this is the case, and the other Starlink mission launches tommorow, Ms. Tree won't take part. Unsure on Ms. Chief's current status as tracker is offline.

Forgive me if I missed it but I don't recall them ever giving us S1 telemetry all the way to the drone ship.
We've had complete S1 telemetry for the NROL-76 RTLS mission, but you are correct, never for an ASDS mission, and never for both stages. I hope this innovation continues.

Hey, some of you might want to take a close look at the Mission Control audio feed here:
https://youtube.com/watch?v=dzxSKe7TF0I
The ground track graphic system was messed up and the regular coverage stream switched away from it for about 30 minutes, but the MC audio stream stayed on it the whole time. At 49m into this video you can see them trying to troubleshoot it, especially for the first few minutes. At one point you see them messing with URLs at the top of the screen (internal "launchx" server, sorry). Finally at 1h19m they got it to stabilize.
At a couple points it shows them switching between the -17 and -18 flights, so I wonder if the order reversal exposed an existing bug in that handling. Or maybe it's just a newer system (witness the new Stage 1 telemetry that One Speed discusses above) and it just had a new bug. Anyway, we only have to wait a day to see it again :) EDIT: nope, several more days ...

A 27 day turn, especially for a ASDS landing is amazing.
It will be fun to see how this proceeds across the booster fleet.

When I first saw the landing on the livestream, I did not expect the landing burn come from so far left of the pictures... I was thinking "oh no it will miss the barge!". But no, I had forgotten how the first stage can approach from a 30-45 degree angle when the landing burn ignites, which then cancels out the horizontal velocity as well as the vertical. 8)

OCISLY & B1060.5 just returned to Port Canaveral from the #Starlink 19 mission. After a definitely rough ride thru heavy Thunderstorms, rough seas & Tornados in the area the booster looks to be in good shape. Another one in the books. #SpaceX #NASA #spacexfleet #Science @elonmusk

That pic above raises a question - what is the state of the lightning protection for the booster when it's on the barge?
I bet there's integral ground and ESD protection on the stage. The body is made of aluminum, so this shouldn't be very hard, just bypassing around sensitive components on the exterior and a ground strap down the legs. This would provide some protection for lightning strikes during ascent as well. The stage is vented after landing, so there won't be propellants to worry about.
The large lightning arrestors at the launch pad probably protect the pad infrastructure as much as they protect the rocket, and are partly historical artifacts. I don't think any pad which SpaceX has built "from scratch" has the same sort of elaborate lightning protection as the kennedy pads do.
But the first layer of protection is most likely, "don't". Don't roll out when lightning is expected, don't launch through cumulus clouds, don't land through them, don't sail through thunderstorms.

Any word on what day Starlink 18 will launch?

It already launched. Starlink L19 launches Saturday night, and L17 launches sometime after that.

Ok, it was 17 I was thinking about.

You can always go to the top post for that info, as it provides a summary of the launch.
Successful launch February 4, 2021 at 01:19 am (0619 UTC) on Falcon 9 (booster 1060.5) from CCSFS SLC-40. Successful ASDS landing on Of Course I Still Love You towed by tugboat Lauren Foss. Fairings successfully recovered from the water by Ms Tree and Ms Chief.
Edit: Also literally at least a dozen pictures in the thread on the previous page.
