Mentioned before: tank weld inspections.
I hadn't seen it publicly mentioned before.  Link?

Oops, I was referencing from memory a week-old post - which upon searching turned out to be L2 :) I hope it does not qualify as L2 leak anymore!

If we have a slip to the 12th what is the launch window? I know CRS launches are instantaneous, but usually there is a short window until they nail down an exact time.

Launch on the 12th means arrival on the 14th?  Which is when MS-05 is leaving with Ryazansky, Bresnik, and Nespoli.  Busy day on the ISS.

Or will they go with CRS-13 launching on the 13th?... too much tempting fate?

It will be the 13th here in Australia. :-)

Looks like there's been a change to the usual 2 day rendezvous, as Dragon is now scheduled to arrive at ISS on the 15th.  I assume this is to avoid having too much happening in the area at once.  Or, it reflects an as yet unannounced delay of the launch to the 13th (less likely, IMO).

Color me impressed.

Very impressive how smooth the re-activation of 40 has gone to date.  I expected multiple attempts with little bits here and there to address.

Great job SpaceX
SpaceX, just a few things planned for 2018: FH, Starlink Prototypes, Block 5, Dragon 2, Increased launch rate.

Seeing the Sun in 1,000 different colors with NASA’s TSIS-1

NASA Goddard
Published on Dec 6, 2017

The composition of that light that falls on Earth matters to understanding Earth's energy budget. In December 2017, NASA is launching a new instrument called the Total Solar and Spectral Irradiance Sensor (TSIS-1) designed to study this question. NASA’s TSIS-1 will measure the Sun’s energy in 1,000 different wavelengths, including the visible, ultraviolet, and infrared, known as solar spectral irradiance. Find out more in this short narrated video.

What will we be able to see from Europe (weather permitting)? Even though Dragon deploy is done both Dragon and S2 should be orbiting close behind the ISS and be possible to see?

CRS-13 launches 16:46:00Z and ISS will be visible here in Denmark 17:56:39Z - 17:58:47Z It is certainly dark enough at that time and the long-term weather forecast is sort of encouraging (-ish).

I really want to watch the launch stream with the kids and then go outside and see the real thing in the sky soon after.

I stopped by Fishlips this afternoon for an early dinner and to take a peek at the ASDS.

There was activity on Go Quest and Go Searcher, that at least to my untrained eye looked like they were making preparations to get under way.

Hopefully, that's a good sign!

maybe i missed a post here, but i thought CRS-13 was suppose to return to LZ-1? and not to the drone ship in the Atlantic.  please correct my understanding

Duh, no, your're absolutely right. 
What was I thinking?


Maybe they were heading out for a beer :-)

Or headed out for a fairing...

EDIT: Doh, I should have known that dragon doesn't have a fairing.

With ELV best efficiency was the paradigm. The new paradigm is reusable, good enough, and commonality of design.
Same engines. Design once. Same vehicle. Design once. Reusable. Build once.

I thought the next launch with a fairing was pushed out to NET 5 January?

Maybe just working on the twins, entropy loves ocean going vessels...

I saw a Dragon pass overhead from Towcester, England (52.13° N). It was shortly after sunset and the ISS passed directly overhead, followed a few minutes later by the dragon, the solar panel fairings and the second stage. They made a cross in the sky. To work out what you might seen you need to know the ground track of the ISS and the lighting conditions. You need the ISS to be passing overhead and for the sun to have recently set (or just about to rise) to get the best viewing as this means the sky is dark but the dragon et al are still illuminated. Having no clouds is nice too.

I was very very lucky as it wasn't planned at all, it just popped outside on the off-chance.

Edit: I saw Dragon on the first orbit, it sounds like it's passing over you on the second orbit, you should be able to see Dragon but I don't know about the fairings and second stage, I would have thought they would have fallen back by then.

Edit2: Watch out for Cygnus too, it should be in  the vicinity. It's moved to a higher orbit so would pass by after ISS and Dragon I guess. I just tried to find a good tool to plot the ground tracks of ISS etc but couldn't find one.

Thank you for the reply. Since you saw it from the UK I suppose that the timing this time will be the same or even better here in Denmark, i.e. the distance will not be longer between the ISS and Dragon chasing it. That is great news.

Our family watched the Atlantis undocked from the ISS and waiting to de-orbit on its final flight. That was great. We have young children again who need to see something like that. Unfortunately, unlike that time the ISS will not be passing directly overhead on the 12th - it will have a max altitude of 12 degrees - but still an experience to remember.
