White and blue lines are different from previous mission including GPS missions. White line seems to start from launch site and be different lines and not the next orbit?

Perhaps the visualization is not programmed right (for a different azimuth/inclination launch) But they did state the parking orbit was within parameters.

Lift off of the #Falcon9 and the #GPSIIISV04 satellite! #SpaceX landed the first stage on the droneship while the 2nd stage continues the mission to deliver the satellite to the proper orbit.

Blue: orbit
White: ground trace of orbit
EDIT: Wrong! Apparently, a glitch in SpaceX's visualization software.

Incorrect. Watch previous streams. But this is most likely a goof in the visualization.

White: ground trace of orbit
I was going to say that but if you look very closely, there is a line going downscreen from Stage 2 that ends on a separate, faint arc that appears to be the actual ground track.
And it goes beyond the surface at the limb at the top of the image.
So those solid white arcs are NOT the ground track.
Note that the one on the left ends just off the Horn of Africa while the blue arc for the next orbit continues to the edge of the image.
What kind of wastrels would dump a perfectly good booster in the ocean after just one use?

Good to know that SpaceX has solved their recent new stage 1 engine problem.
Should bode well for Crew-1.

Ground track is gray and dim like before. The white line was before both the actual orbit and projected orbit, and blue was projected next orbit (white line changed blue behind the Earth). Now the white line is separated orbit track. I guess it is glitch in graphics; those biological cat girls get (white) nail polish everywhere. (Not problem with robotic ones)

LOS New Foundland expected.


Newfoundland is all one word. It's pronounced 'new-fund-land". Locals call it the rock (or God's country)

It's actually quite a spectacular place to visit (but I would never live there...it gets cold in the summer when icebergs show up in the local harbours!)

Great coverage all. So routine we forget how difficult this business is.

Yep, the animation is off, if it were right then stage 1 would be swimming with the fishes.  :)
