Thread for the Starlink 5-2 group launch.

NSF Threads for Starlink 5-2: Discussion

Launch January 26, 2023, at 09:32 UTC (4:32 am EST), from Canaveral SLC-40, on booster 1067-9.  The first stage is expected to land aboard Just Read the Instructions.

Main payload: 56 Starlink satellites, also the Starlink upgraded network Flight 2.

Launch to a mid-inclination orbit on a southeastern trajectory.  Initial orbit is 212 x 338 km at 43 degrees.

Starlink v1.5 satellite mass is now about 300kg after the addition of laser ISL terminals.

Please use the Starlink Discussion Thread for all general discussion on Starlink.

Check the Starlink Index Thread for links to more Starlink information.

Rideshare aboard this launch?  It wasn't on Starlink 5-1.
<snip>
D-Orbit put out a press release yesterday saying they have an ION launching to mid-inclination orbit in Q4-2022, and will be operating at 270km.



Belated cross-post:
Ben Cooper's Launch Photography Viewing Guide, updated December 25:
Quote
FALCON 9
...A Falcon 9 from pad 40 will launch GPS III-6 for the U.S. Space Force on January 18. Upcoming launches include more Starlink batches. A Falcon 9 from pad 40 will launch the Amazonas Nexus satellite for Hispasat on late January or February. And a Falcon 9 from pad 39A will launch four astronauts to the ISS on Crew-6 on February 19 at the earliest, in the middle of the night EST.

Speculation:
This could launch from LC-39A after USSF-67 and before either SpX-27 or Crew-6 in February.  SLC-40 seems fully booked for January.

By the 24th both 39A and 40 will be able to support a launch. 39A needs a few more days beyond the min cycle time of 6 days to be able to reset to F9 from FH. That is not much estimated at about 2-3 days. Meaning there is assets and pads availability to get 2 more launches in this month. 16 days open for one pad (39A) and 13 days for the other (40) since their last launch and to the end of the month.

As to which actual pad this launch would take place on it is a mater of tracking the payload. But since both are likely Starlink payloads which launch each pad supports may be a bit difficult to figure out. Flip a coin at this point.

Dividing 16,700 kilograms by 54 and multiplying the quotient by 56 equals a total mass of about 17,318 kilograms.

Agree this is the likely cause, but I suspect SpaceX has other criteria for static fires.  For a completely made-up example, suppose they need to replace the first stage avionics.  This is presumably less common than changing an engine, but if it does happen SpaceX may wish to confirm the fix with a static fire. I'd imagine there is a checklist for every part that might be replaced/refurbished on the first stage, stating whether that implies a static fire is needed.

Yes, @SpaceX has explicitly confirmed that the time has shifted 10:00 minutes "to optimize orbit raise and get sats on station faster."

According to the webcast, it's the heaviest F9 payload ever at over 17,400 kg. If we divide it by 56, a single satellite mass seems to be around 310.7 kg.

For one of the 54 satellite launches they said that the mass is around 16,700 kg (I think they said "around", not "over", but I would have to check). It gives us a mass of a single satellite around 309.3 kg, so it's pretty consistent.

Minor issue picking it up as it came behind the trees, but will be a trivial fix. Then rock solid until Falcon went into the clouds.

Specifically, while waiting for the rocket to rise above the trees, the object detection class used to track the rocket after it becomes a tiny dot in the sky had a false positive on a pad light. Solution will be to not listen to detections of such class until post-staging.

Since a rocket that is a tiny dot in the sky looks the same as star or a bright light, there are inevitably a lot of false positives in this specific scenario. Right now I'm going to mitigate it by being smarter about considering whether the detection is likely to be valid.

One more post about the payload mass.

So during the webcast they said that the payload mass is "over 17,400 kg", but also "around 38,000 lb". The logical upper bound seems to be 38,500 lb (otherwise it would be "around 39,000 lb"), which gives us around 17,463 kg.

I have also found the previous launches for which the payload mass was announced directly by SpaceX:
Starlink Group 4-12 (2022-03-19), 53 satellites, ~16,250 kg, ~306.6 kg per sat
Starlink Group 4-23 (2022-08-28), 54 satellites, ~16.700 kg, ~309.3 kg per sat
Starlink Group 5-2 (2023-01-26), 56 satellites, 17,400-17,463 kg, 310.7-311.8 kg per sat
GO for launch, GO for age of reflight

Congratulations SpaceX team on yet another incremental improvement of their workhorse rocket's performance.  And thank you NASA for signing off on / not standing in the way of these tweaks to the system that is used to launch their astronauts.  They could have chosen to insist on a design freeze once SpaceX's CCP solution was certified after Demo-2 ...

I'm looking forward to OneSpeed's analysis again, to see if they changed anything in the flight plan, e.g. the throttle bucket.

Did this go to precisely the same orbit as the previous comparable flight, or maybe a little lower?

SpaceX launches two CCP (i.e., "NASA astronaut") missions a year, and this is supposed to drop to one per year. If NASA had forced a freeze, SpaceX might have chosen to use one or two boosters with the frozen design while continuing to improve the rest of the fleet. Fortunately, this did not happen. All this is might-have-been and therefore not very productive. SpaceX might have declined to extend past the original option of six CCP flights using the "frozen" design to induce NASA to accept the newer boosters. Starliner might have flown in 2021. The Russians might have declined to extend ISS past 2024.

Fortunately, NASA made (what appears to be) the right choice. Of course, it's easier when you can choose flight-proven boosters after the tweaks are made.

17.4 Metric Tons, what an accomplishment.  I suspect the lower inclination of Shell 5 helps with the mass increase, but they just keep squeezing more out of F9 when they can. 

Very impressive.

Edit: Also, 5th and 6th flight of fairing halves, they've come along way on that reuse project.

Would be great if we had even a rough estimate for the mass of the tension rods, which I assume are included in this 17.4t value.  They're not much, but would give us a more accurate estimate of the per-sat mass

Is there some mass between the top of the second stage and the sats that is counted as payload?

Just curious, why would you need a more accurate figure than 310 kg +/- a kilo or two?

Would be great if we had even a rough estimate for the mass of the tension rods, which I assume are included in this 17.4t value.  They're not much, but would give us a more accurate estimate of the per-sat mass

Is there some mass between the top of the second stage and the sats that is counted as payload?

Just curious, why would you need a more accurate figure than 310 kg +/- a kilo or two?

The 4 tension rods keep the sats from springing away prematrely. THey are wrapped around the sats.
Why would I need...?  Because I am obsessive.  And because it's interesting to track the increase on the sat mass with different versions.
And because a few kg per sat add up when you total 3000  - or ultimately 30000 - satellites

I find it interesting that the recent list of heaviest payloads launched by a member of the Falcon 9 family in it's various configurations involved a Falcon 9 booster landing on a barge.

Here is a comparison of the second stage webcast telemetry from the Starlink 2-4 (70°), 4-31 (53.2°) and 5-2 (43°) missions.

Because of the SpaceX telemetry inertial frame of reference, the velocities at SECO are 7,661, 7,520 and 7,472 m/s respectively. These differences reflect the difference in ΔV required to reach those orbital inclinations, even though in the orbital frame of reference, the velocities are the same, at about 7,820m/s.

They also reflect the differences in payload with 51, 53 and 56 satellites respectively.

SpaceX still lists 22.8 tonnes as the Falcon 9 LEO payload capability on its web site.  Presumably that would be for a fully expended vehicle, to a low inclination orbit, etc., but since that number is a few years old, I wonder what it would be now.  Then again, does the U.S. even have any LEO payloads this heavy?  I think not. 

My guess is that the 17.4 tonnes includes the PAF and the tension rods along with the satellites, so maybe subtract 200, 300, or 400-ish kg.

The B5 expended boosters (bar in flight abort) are all going to GTO where you can use extra propellant to get nearer to GEO and extend life of satellites. Less mass is done to GTO than to LEO. LEO mass is high enough that to test that, it needs to be doing something large like a constellation where payload can be broken down more efficiently into more droneship landings rather than fewer expendable launches.
 
Seems straight forward rather than interesting?

.

How much could 17400kg be increased if launching to best possible (28.4?) degree inclination rather than 43 degree inclination?

We should have a closer data point when they start launching to the 33 degree shell.
If you're happy and you know it,
It's your med's!

This is very rough, but from β = asin(cos(mi)/cos(ϕ)) and Vorbital = Vinertial - Vearth

From a latitude (ϕ) of 28.5° to a circular orbit:

Inclination (°)_ΔV (m/s)_Satellites_Payload (t)
707,6415115.8
53.27,5185416.7
437,4535617.4
337,4015818.0
28.57,3825918.3

SpaceX support ship Bob should arrive at Port Canaveral this afternoon after supporting Starlink 5-2.

Hopefully carrying a fairing half... or two....

Just Read the Instructions and Falcon 9 B1067 should arrive at Port Canaveral in the early hours of Sunday morning.

With conflicting cruise traffic, JRTI may be holding off until after ~6am to enter the port.
