T+15 minutes. Over the mid Atlantic.

Congrats to Korea and SpaceX ! Did they just say " 57th landing" ? It seems like the first one was yesterday! Still mind-boggling every time we see it, even more so on the drone ship. Thanks NSF.

Is it only me or do others perceive JRTI compared to OCISLY as well as an old, rusty mule?

It's younger than OCISLY, it's just gotten a bad looking deck due to lack of re-painting and having thrusters built onboard it.

Or SpaceX no longer considers it critical that the droneship has a nicely painted SpaceX logo... And why should they?

T+20 minutes. Heading towards Africa.

That does look like a down the pipe landing.

FWIW, I prefer the Serenity look. Working vehicles have no need for makeup & lip gloss.

AOS Gabon.

T+25 minutes and 32 seconds. One minute to second ignition.

Ignition!

Fairing Catchers are hunting...

Ms. Tree heading east at 8.7 knots as of 4 minutes ago.

Unlikely that SpaceX will have completed the go/no-go poll on the catch yet. Occurs around T+40 minutes usually.

T+30 minutes. Over Africa.

AOS South Africa.

One minute to separation.

Steven Pietrobon · « **Reply #172 on:** 07/20/2020 10:03 pm »

Payload separation confirmed!

Wrapping up coverage.

End of SpaceX coverage.

Congratulations to SpaceX and the South Korean Agency for Defense Development for the successful launch!

When the second stage refired it was about over Lagos Nigeria. I wonder anyone looking up see bright star over head then all once see fire coming out of it. Could they see it from ground?

FutureSpaceTourist · « **Reply #177 on:** 07/20/2020 10:20 pm »

Yes, a first!

Both fairing halves caught from space by @SpaceX ships!

Steven Pietrobon · « **Reply #178 on:** 07/20/2020 10:21 pm »

From LEO insertion, predicted 2457.0 m/s for second stage and 1763.0 m/s for payload to GSO.

Enter initial perigee height (km): 164
Enter SpaceX speed (km/h): 26675
Enter initial orbit inclination (deg): 27

Estimated inertial speed = 7834.8 m/s
Estimated apogee height = 262.7 km

Enter required inclination change (deg): 27
Enter final orbit height (km): -1
Geosynchronous altitude = 35786.0 km

Burn at 164.0 km: theta1 = 2.05 deg, dv1 = 2457.0 m/s
Burn at 35786.0 km: theta2 = 24.95 deg, dv2 = 1763.0 m/s
dv = 4220.0 m/s

OMG, this is fantastic. Can't wait to see side by side video.

I wonder if the new software is complete and helped out. (must be that right?)
