SpaceX F9 : Transporter-3 Rideshare : CCSFS SLC-40 : 13 January 2022 (1525 UTC)

Any answer??

Gunter said that Thingsat was on one of the Stork satellites.  I don't understand what else you're asking?

This page tells a payload on ion scv 4 to be hyperspectral payload. I need to to confirm that is it thingsat Or is thingsat different and hyperspectral payload different

Thingsat is a payload on one of the STORK satellites, not on ION SCV 004. The hyperspectral payload is on ION SCV 004. Therefore Thingsat is NOT the hyperspectral payload.

So there are in total actually 2 hosted payloads on this mission. Thank I had problem since thingsat wasn't mentioned in the lead of this page. Will it be required in the lead??

Falcon 9 lifts off carrying 105 satellites for SpaceX’s 3rd dedicated rideshare mission.

With this mission in the bag, there are now 3 #Falcon9 boosters with 10 flights under their belt. Quite an impressive feat!

Nine Merlin engines get the party started!

The ground equipment used to launch rockets is as impressive as the rockets themselves. Here, you can see part of the strongback as it tilts away from Falcon. And see if you can spot the tiny weather vane on the lightning tower.

Manually aligned 22 tracking photos I made this morning (spanning ~2 seconds of real-time) of Falcon 9 breaking through the sound barrier & igniting its center engine to return to Cape Canaveral 🚀 That shadow! 🌤

ThingSat is just one of several payloads on the STORK-1 satellite.  It's not a separate satellite.  It's not a hosted payload on ION.  I really don't know what else to say about it.

Thanks for thingsat issue but I don't  know why ars technica is telling that B1058 launched 550 satellites till now as my calculations tells it launched 1+1+60+1+143+60+60
+54+53+105=538 till now

What does the extra 12 at minimum are for them

Bob has returned from his fishing trip with two Falcon 9 fairing halves involved with the Transporter-3 mission.

People still think "Well it's only fairings" - but they cost millions of dollars and thus recovering and reusing them is a big deal.

Does anyone know why fairing jettison is so late on Transporter 2 and 3 missions? Most missions (see Turksat, for example) jettison the fairing at about 105 km (soon after staging).  This is just about what you would expect, since the criteria is that free molecular heating should be about the same as heating from the sun.  Transporter-1 did this as well, although slightly higher (112 km).

But Transporter 2 and 3 jettison the fairing at about 135 km, more than a minute after staging.  This would seem to make them harder to recover, as they would be further down-range than they would be if jettisoned sooner, and falling from higher so likely more spread in landing locations.

Transporter-1 and Turksat were droneship landings, while Transporter 2-3 were RTLS.  This means that Transporter 2-3 likely had a more lofted trajectory, so less far downrange for the same time.  But it would still seem to make sense to toss the fairings as soon as possible. 

Maybe they delay the fairing jettison until after the dog-leg completes?  The timing fits, but they did not do that on Transporter-1.

If there is a payload-related reason for the high jettison, it bodes poorly for the RocketLab Neutron rocket.  Their equivalent of fairing jettison happens right at staging, since the fairing is attached to the first stage.   This is presumably much lower than 136 km.

Can't answer your primary question, but I believe the fairing recovery systems still have the ability to steer to a given GPS coordinate; they just land in the water.

IIRC, there was some cubesats carry aboard the cargo Dragon (CRS-21) for deployment from the ISS.

I suspect you have mostly answered your own question below:

Maybe they delay the fairing jettison until after the dog-leg completes?  The timing fits, but they did not do that on Transporter-1.

It does seem reasonable that fairing jettison should not be attempted during a yaw maneuver.

As you can see from the first screen grabs at MECO, Transporter-1 performed most of the dogleg to SSO using the first stage, while 2 and 3 mostly utilised the second stage.
Using the first stage to perform a dogleg would be less efficient for a RTLS, because the dogleg has to be performed twice, once for the boost phase, and then again to yaw back to the launch site. However, Transporter-1 landed on a drone ship, so no second dogleg was required, just downrange positioning of the drone ship.

As you can see from the second diagram, Transporter-1 had both a longer boost phase, and a more lofted trajectory, so the second stage was well above the Karman line when fairing separation occurred at about T+179s. Because the second stage only needed to perform about a 7 degree dogleg, which it appeared to do gradually over the length of the burn, with minimal cosine losses, it might have been considered more efficient to lose the fairing mass as soon as possible before commencing the yaw.

However, Transporter-2 and 3 SESU was well below the Karman line, at about 80km, too early for fairing jettison. Because doglegs are most efficiently performed at lower velocities, and Transporters 2 and 3 had a much larger second stage dogleg to perform, SpaceX must have decided to start a much faster yaw maneuver as soon as possible after SESU, and wait until it was complete before fairing separation. Again from the second diagram, the Transporter-2 and 3 doglegs completed at about T+233s, about the same time as fairing separation.

Another consideration is that although the IIP for Transporter-1 was never over a populated area, the ground track was closer to the Miami coast than for Transporters 2 and 3. Perhaps they just decided it was a better look to fly further off the coast?

What a booster landing really sounds like from Cape Canaveral Space Force Station.

Any list or total for those satellites so that I can get the exact  total no. of satellites (that is definitely above 550 satellites) launched by booster B1058 till now.

Please atleast provide me with the total no. of cubesats aboard crs21 so that i can get the correct sum of satellites launched by b1058

Some of the best F9 tracking shots in this one

[wjbarnett]

Beautiful shots and tracking! Really get to see the green TEA-TEB light on the Entry Burn, first from the center engine and then the two side engines. And the exhaust really changes shape there, then changes again at Entry Burn shutdown where it appears the side engines shut down earlier than the center.

And the exhaust really changes shape there, then changes again at Entry Burn shutdown where it appears the side engines shut down earlier than the center.

I would expect that's because the center engine has more thrust vectoring capability than the sides, and is used to null out any asymmetry in the engine shutdowns.

As a note, we are all volunteers here. No one owes anything to anyone else. Please keep that in mind when making demands.

There were no Cubesats on the CRS-21 launch.

We're delighted to announce that the #ISILAUNCH36 mission has been a complete success, with 66 #ISISPACE customer payloads being deployed and confirmed contacted during the #Transporter-3 rideshare mission. Thanks to @SpaceX for the ride. Already looking forward to the next ones!
