If there is a second payload they really don't want to talk about it.

Anyone want to explain what this "parking orbit" has to do with launching a Globalstar sat?  ::)

Looks like the mission profile could be:

1. Direct injection into a 533 x 533km orbit (1:34:51 period)
2. Release payload 'X'
3. SES2 to raise apogee to a 533 x 1200km (ΔV about 174 m/s)
4. SES3 to circularise at 1200 x 1200km (ΔV about 170 m/s)
5. Release Globalstar.

Can we get an orbit parameter judging from the altitude and velocity readouts (the change in them after SECO-1 for example), plus inclination from drop zones?

MECO > Stage 1/2 separation > SEI-1 > fairing separation (not shown, and payload(s) not shown either)
Hmmm

Night vision video shows rocket activity, city light pollution, and lightning illuminating thunderstorms.

More launch progress graphics than usual.  ::)

Entry burn > landing burn > successful JRTI landing > SECO-1 (no video coverage of this)

No images shown from the front facing second stage camera, no fairing separation shown (or even mentioned!)

Very suspicious, and only reason that I can think of as to why... there is more inside the fairing than just Globalstar FM15.


・They do not deliver fairing separation footage
・They don't even try to explain the situation.
・But they will deliver the second telemetry and also the orbit map.


I have no idea the position of this mission.
Is this a top secret defense mission hidden in a commercial mission?
Or is there a SpaceX in-house secret experiment payload?
Or is this their epic joke and are we being teased?

Hence SpaceX have their smoothest talking announcer continuously talking to distract viewers from the abnormalities of this launch. Jessie Anderson has been MIA from launch webcast lately.

They're pretending this is just a normal launch, but without 2nd stage video, crazy ;D

I wonder if they'll start showing 2nd stage video after they leave this initial orbit.

Better not be. I hope whatever payload separation device is used works properly.

As we wait for SEI-2, graphics and Starfish Prime's funky tunes.

It is strongly hinted in the NSF launch article.

SEI-2 > SECO-2

1st view forward on 2nd stage!  What was on top of the frame of triangular units?

More views of same as we see the usual preprogrammed rotation of external 2nd stage rocketcam views--stage is in view of the Tasmania ground station.

Yes, video stops with expected Tasmania ground station loss of signal.

FM15 nominal orbit insertion callout after SES-2/SECO-2 and  Stage-2 and payload views have been resumed.

Front view was shown. Definitely looks like a dispenser that had something else on top of FM15.

Nice, at least we know it's separated successfully this time. Otherwise with no customer claiming the payload we won't even know what happened to it...

Looks like the same deployer for Starlink on the Transporter missions

If there was just a stack of Starlinks on top for "ballast", why that would not be disclosed?

The altitude of the parking orbit was very close to operational starlink orbit (535km vs 550km) and inclination was off by 1 degree (52 vs 53) but if that is the explanation, why the secrecy?

I guess we'd know if some new Starlink sat TLEs appear, not like they could keep them off the books if its just in-house payload.

And looking closely, the adapter looks similar, but not exactly the same. So probably not the explanation.

There are differences. There were DoD/SDA Starlink bus related pressers and discussion in the past. SDA test and evaluation payloads have launched on several different rockets and spacecraft to to date with PIRPL being one of them.
