Beautiful pics, with perfect sun position! They must have planned that.  ::)
I'm looking forward to the raw launch-to-landing rocketcam video.

Photos now they've got the reel of film back from the ASDS:

Hey Chris, do you reely think they're still using film...?  ::)
Reel of film/card of images. Probably just putting it in terms we older folks can understand.   ;D

I wonder how many computer screens will get that photo as a background today?!

The following one is pretty stunning, too - https://www.flickr.com/photos/spacex/32351549066/

ok, that's cool.

Looks almost like a notional airbrushed "artist concept" of what it is.

Nice landing shots. Is there a clean landing video, without all the dropouts?

What a shot!! Styled like a medieval painting of a mighty angel descending from the heavens! What luck to get that alignment of the sunshine! Or maybe they positioned the ASDS just so for just that purpose... :D

Or there were multiple cameras, they got lucky and the is the most impressive one to realease.
Excited to be finally into the first Falcon Heavy flow, we are getting so close!

Unlikely given this: http://forum.nasaspaceflight.com/index.php?topic=41751.msg1628106#msg1628106, seems to me the plan is to bring it down in a few hours...


You are suggesting that the plan is to bring down the stage a few days after launch?

No, as I said, I think the plan is to bring down the stage a few hours after launch. Launch is 17:54 UTC, Jan 14th, the first time range in input~2's message is 19:46 to 20:12 UTC, Jan 14th, so about 2 hours after launch.

One would hope SpaceX use something slightly more '21st Century' than a reel of film.  Surely you mean "USB stick" or something similar??   :P
 
With sufficient thrust, pigs fly just fine - however, this is not necessarily a good idea. It is hard to be sure where they are
going to land, and it could be dangerous sitting under them as they fly overhead.

...Hey guys, the 11th object (if it's still 2017-003M) has changed orbit..

Apogee 868 km
Perigee 739 km
Inclination 89.91

http://stuffin.space/?intldes=2017-003M&search=2017-003

EDIT: Space-Track.org is not showing this update for me yet, still 623x608.
Since stuffin.space uses space-track data, I'm not sure how to reconcile the two. A bug?


Norad TLE data seems to confirm:

2017-003L

I think the cameras might belong to Ben Cooper of Launch Photography, which would explain why he's been posting photos from western locations on Facebook lately, and cameras use SD cards, not USB sticks.

On another subject regarding those photos, looks like the stage did some significant walking in the short time before the crew was able to board and secure it.

Not saying that's not the case.. but what gives you that impression?

Oh, I just deleted that part before seeing your post. On further scrutiny I realized the photo I posted was from a different angle, from the side, and the stage just hadn't landed dead center between the bow & stern. The previous photos were from the bow or stern, and the landing was dead center between the 2 sides.

No probs.  In the video posted of the landing, the stage was certainly reeling around like a drunken sailor on the ocean swell, so if it didn't move significantly in the time it took them to secure it, that's a good indication that the landed stages are surprisingly stable.

They're saying the new numbers are nonsensical.  Odd.

It's not that unusual to get garbage in the TLEs.
My current theory:
The TLEs for 41927 prior to this one referred to a nonexistent object created by confusing measurements
of Iridium Fred on one orbit with Iridium Joe on the next orbit.
They just realized this - oh, there are only 10 objects!
They then reassigned 41927 to a newly found debris object from an unrelated launch (maybe from an old Transit sat judging from the orbit). But they forgot to change the international ID.
If my theory is correct, the international ID for 41927 will change in a day or two.
Complicated, but it wouldn't be the first time something basically identical has happened
