Someone took a fabulous long-duration high-resolution photograph of the Zuma launch.

Be sure to zoom in to the portion after first stage engine cut off. Among other things at various places in this photo you can see all three of the returned launchpad burns, and you can even detect the sequence from one engine to three engines back down to one engine for the reentry burn.

[edit: this is actually a composite of three separate long-duration photographs each of two to three minutes duration, and with considerable differences in sensitivity to adjust for the varying light levels of the primary target of interest]

Zuma satellite failed to separate from 2nd stage and is presumed "lost".  Damn!

 According to

 According to https://www.theverge.com/2018/1/9/16866806/spacex-zuma-mission-failure-northrop-grumman-classified-falcon-9-rocket However, a previous report from Wired noted that Northrop Grumman provided its own payload adapter for this mission. And if that payload adapter failed, it would have left the satellite still attached to the upper portion of the rocket. That’s certainly a mission failure, but it wouldn’t necessarily be the fault of the Falcon 9.

Not looking to place blame.  Just shocked that something we take for granted doesn't always go as planned.

Or it is the preference of the owner of the payload to construct a certain narrative ..... complete with plausible backstory .... ;-)

Cheers, Mike.

Yes, yet one more option to the "lost" payload - it really isn't lost.

Falcon 9 Heavy (the three

Falcon 9 Heavy (the three tube model) had a first try at a possible static firing today.  It got pretty far along, with propellant loaded, but they cut things short without lighting the candle.  Sources commenting on their plans assert that this static firing is planned to be several times longer than typical for Falcon 9 at the Cape--12 or 15 seconds have been mentioned.

The next approved opportunity for static firing is currently stated to be Friday Florida time anytime between 10:00 a.m. and 4:00 p.m. local time (1500 to 2100 UTC).

Most recent estimates of the soonest likely launch dates are very late January to very early February.

Gary, what splash down do you have in mind?

The Dragon Capsule coming

The Dragon Capsule coming from the ISS, splashdown in the Pacific.  It will be a bit before the next one.  Just wondering if there is footage of any of them.
