I was hoping this was going to stay closer to the original launch window at the end of this month since I was going to be down there around then. Too bad.

Wow. Pretty heavy bird, and capable too. :yes: Should have a good, long service life if nothing goes wrong with any of the systems.

If spacexstats.xyz can be trusted (which I think they can) then this will be their heaviest satellite yet, with the current one being Echostar 23 coming in at 5,500 kg.

GEO bird yeah, and an expendable F9 could do 8+ tonnes to GEO. A fully loaded Dragon pushes almost 10 tonnes, and Dragon 2 even more. The heaviest payload Atlas V has ever pushed uphill was Enhanced Cygnus OA-4 at 7.492 tonnes.

Funky music

 

Confusion as to if they're late or on time for 1920. LOX load callout may have just been delayed.

You wouldn't think it was a heavy bird ... nicely done. That S1 was pushing it with power to spare. :D:yes:
