Some kind of actuator issue. is this the flight where they want to test
recovery of a stage?

Yes, but the actuator issue was on the second stage not the first stage, which is the one they will try to recover.

With the new launch time being bumped up by 1 hour, it will make the launch and recovery effort take place in pre-dawn darkness. Not sure how easy it will be to observe the landing attempt should it be video streamed.

Note that this flight, Dragon is returning cargo and is to land and be
recovered in the Pacific.


Just to be be clear I was referring to the attempt to recover the first stage on the SpaceX autonomous drone ship out in the Atlantic off the coast of Jacksonville Fla. Not the Dragon capsule.

I was wondering about lighting conditions. How far east is the recovery?

Quite a bit, but not enough. The original landing site was given as this:

/quote
According to data from maritime tracking websites, the Marmac 300's [SpaceX ASDS platform] tug [ELSBETHIII] and its control ship [Global Quest] were nearing the landing zone early Monday.

Information released in notices to pilots, mariners and in a federal regulatory filing show the ships will be positioned near 30.8 degrees north latitude and 78.1 degrees east longitude.
/end-quote

from this cite:

http://spaceflightnow.com/2015/01/05...ocket-landing/

Both ships seem to be back in JAX now, but not sure about the ASDS. It would be weird I think to burn ASDS fuel station keeping for this long and it takes a day to sail out to the landing site. It would seem likely that if both ships are back in port, so is the ASDS. I predict that if they are back in JAX they will set sail again tonight or early tomorrow.

The landing zone for the next attempt might be different, depending on launch inclination etc. for the next try. But if it's close to the old site, that would put it approximately 200 km east of the launch site, 250 km due east of Jacksonville by my rough approximation on my computer screen.

Sunrise prediction for 1/9 in Jacksonville Fla is 7:24 AM, so beginning of twilight at 1 hour earlier put us at 6:24 AM and launch is scheduled for 5:09AM. This isn't far enough east to make a difference. It will be landing in the dark if the landing site remains unchanged.

This is obviously wrong in the original article. It is 78.1 degrees west.

[Global Quest] = [Go Quest] *sigh*

New launch date:

@SpaceX selects Sat., Jan 10 at 4:47a ET to launch #ISScargo mission to
the @Space_Station


Does the stage one have any flashing light as it falls back to earth and
floats ? I assume that once close enough, recovery ships would have
large floodlights to illuminate the "worksite". But flashing lights
might be all that is needed for the ships to get close enough.

Close enough to what?

You do realize the stage is intended to LAND on the barge, not float in the
ocean.
