Static Fire is NET Thursday per the L2 Status report (based on the launch date Bulgariasat-1 launched on).
Big ask. Need the shakedown report for 39A post launch and so on. Will update as we go.
-
James Dean reported earlier this morning that the NET date could be as soon as July 2nd. This is or course highly dependent upon pad flow, as Chris mentioned.

reminder... update thread.
Safety first, rats, etc. deleted. Left Helo's "more time" as that is sort of an update I guess????
PS, see the party thread if you don't get the joke there about picks on an expendable mission.
And please use the update discussion thread,.... or the party thread for your comments, questions, quips, etc.
http://forum.nasaspaceflight.com/index.php?topic=41426 (discussion)
One eager low post count member got two posts deleted. I feel bad. But not that bad.
Edit: I also feel stooopid for saying update when I meant discussion. TWICE!
-
FWIW, audio of the LD call on the countdown net after the abort.

SpaceX close-up taken yesterday
-
Not actually official yet, but the way KSC is acting on the notes of roadblocks and preps suggests they are deep into activating the 24 hour scrub turnaround, so another attempt today. Caveat is they can take it down to polling points, so yeah - but let's go with another attempt until we hear different.
-
Weather is perfect. #Intelsat35e @SpaceX

A launch tonight and this would still be the shortest time between two launches from Kennedy. Any further delay and the gap from BulgariaSat-1 will be longer than that between Skylab 1 and Skylab 2 (i.e. Skylab itself and its first crew) in May 1973.

Weather still looking good
I spy with my @SpaceX eye ...

-
Just over 2hrs to the opening of today's launch window. This is the current radar. Storm is to the west and holding position about 13nmi from SLC-39A -- which is good.
-
More weather context. The storm has been building, consolidated from the west. An outflow boundary is moving across the state, originated around Orlando.
-
Radio Frequency link checks with AFTS complete at this time.
-
This storm is building up right at the 10nmi line from SLC-39A. Still good... as long as it stays there.

-
Countdown clock as been adjusted accordingly.
-
Current view.
-
T0 reset to 19:52 EDT due to weather. (Delay of 15mins)
That would be because of the cell to the northwest that breached the 10nmi zone.
-
SpaceflightNow clock has reset. We're at T-1 hour 27 minutes.

-
And weather does appear to be building inside the 10nmi zone around SLC-39A.
-
SpaceflightNow clock just got pushed back again.
-
New cell developing well inside the 10nmi zone.

John says they do not at this time know, and we'll have to follow on social media for updates. If the investigation allows it, there will be another try tomorrow. But nothing yet reported on the root cause.
-
Still don't know reason for scrub.
-
THIS IS WHY STATIC FIRE IS SO IMPORTANT. Testing these late abort mode and procedures.
ULA and Orbital ATK (and probably other launch providers) rehearse abort procedures for every launch and they don't do static fires.

SpaceX update. Launch now NET Wednesday, 5 July.
"Out of an abundance of caution, SpaceX will be spending the 4th of July doing a full review of the rocket and launch pad systems. The next launch opportunity for Intelsat 35e from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida is now no earlier than Wednesday, July 5 or Thursday, July 6. Additional updates will be posted to this page as they become available. "
-
SpaceX is requesting the 5th from the Eastern Range, per an e-mail to the media just now. That's a bit more definitive than 5th or 6th, per it being an update.

Looks like they are working on it at the pad instead of rolling back.
-
The 45th have done an updated weather forecast for tomorrow, but the link on their website isn't working yet!
However, I don't think they update forecasts unless range approval has been granted?
-
Well going by the latest spacex media email we will know more between 10 and 10:30am tomorow if there will be a launch later in the day or a longer launch delay.
-
KSC acting like they are pushing for a launch on the 5th with the roadblock notices, etc (like the last time). Certainly points to the range being able to support. All depends on the resolution timeline.
-
F9 going back to vertical right now:
-
Falcon is almost vertical, S1, S2 are just barely hidden by the RSS

Looks like the F9 is vertical:

Now the lights are on the Falcon itself:
-
SpaceX say they are currently moving towards a launch tonight. Window opens 7:37 p.m local.
Latest is for planning purposes for media that are covering the launch. Remains subject to change, but that's what we'll all go on, that they are planning the latest attempt tonight.
A more definitive statement below.... :)

Congratulations to SpaceX and Intelsat for getting this powerhouse into the planned GTO orbit.
I'm also impressed that this version of Falcon 9 can lift payloads that Falcon Heavy could have launched if not for its own delays.
-
Nice! 3rd times the charm! Congratulations to SpaceX and Intelsat and everyone else involved!
-
Congratulations to SpaceX and Intelsat on a successful launch!
-
Congratulations SpaceX.
Great to see your launch cadence so high, after building the capacity over the past several years
Keep the high pace up as you continue to set records for you long-term vision and consistent execution!
-
Three times is a charm! Nice boring flight. Great job SpaceX, NSF, the range, and everyone else involved!
-
Congrats SpaceX!
Thanks to Steven for the coverage
-
John confirmed on the webcast that the range deferred their maintenance window a day in order to provide this launch attempt.
Congrats to all!
-
Webcast ending.
Congratulations to SpaceX and Intelsat for the successful launch!

Congrats SpaceX!
-
Congrats to SpaceX, Intelsat, NSF and all concerned. Faintly sad that our drama queen S-1 had to splash down.
-
Congratulations to SpaceX, Intelsat and everyone involved in this beautiful launch. (Especially relieved this one’s behind us!) Thank you to Chris, Chris & Steven for making this launch, as always, come alive in memorable words and pictures.
Special kudos to all those SpaceXers who have worked such long hours over the past 12 days launching 3 successes out of 3 attempts. Hope you get a well deserved rest while the range is closed!
-
Nice job SpaceX! :)
And nice of them to thank the Air Force range for allowing them to launch, by delaying their planned down time one day.
10 launches so far this year. By themselves more than any other country!
-
Congratulation! :-)
-
Kudos to Steve for the coverage. Well to the SpaceX team for continuing to mature this excellent launch system. How many more F9 launches this year before we get to the 'Big Boy' FH?
-
EPIC congratulations to SpaceX and Intelsat.
I knew that if I don't watch live it'll launch, so I didn't open YouTube until T+0:00:02
-
Congrats to SpaceX and IntelSat! After this flurry of launches, I might suffer some withdrawal symptoms waiting for the next one.
-
Congratulations to all concerned for another successful launch in quick succession. But now we hit the pause button until next month.
-
On one hand, this launch took 3 attempts to get going. On the other hand, it was still less than 2 weeks after the previous launch from this pad! Just like how expendable launches have quickly become strange for SpaceX, so too have launch-by-launch delays and extended downtime - makes the range's upcoming multi-week downtime seem absolutely atrocious! :P
Anyways, congratulations to everyone involved in today's launch! Here's to many more in the future!
-
Congrats to SpaceX and all concerned, keeping an extraordinary cadence. And thanks to Chris, Chris, and Steven for extraordinary coverage as usual, this one was persnickety.
-
Congrats SpaceX and Intelsat.
Thanks for the launch window stretch USAF.
-
Congrats to SpaceX, Intelsat, KSC, and 45th SW for a great launch and deployment.

Well done SpaceX,
You had an abundance of caution,
and you came through, with a Great Launch...
Much better than having launch fever...
and Thank you Intelsat for your confidence
in SpaceX and sticking with them... they
will only be getting better, with the experience...
Thanks too to Chris, Stephen and the Team for
this Truly Epic Website and Coverage of
ALL THINGS SPACEY :D
Cheers Gramps...
-
Big congratulations to all the SpaceX and KSC folks who worked through the Fourth to make this happen. I hope many of them get some well deserved downtime during range maintenance. Steamroller, forward!
-
Congrats!
See you in August SpaceX!
Hopefully we will get an ITS update or a spacesuit unveil in the meantime. ;)
-
Once again, "Bravo!" SpaceX continues to grow confidence in the F9 as the inauguration of Dragon2 and crewed missions nears.
-
Congrats to SpaceX!! Now you get a break from all that hard work of the last few weeks!
-
Congrats to the SpaceX team.
Glad you got this one completed before the Eastern Range shuts down for several weeks.
-
Congratulations SpaceX and Intelsat (finally!) :)
By my reckoning still a record (just) for the shortest duration between two SpaceX launches from the same pad. So yet more proof, if it were needed, of the amazing launch cadence established this year (and of course with an East coast launch as well in between). Bravo!
-
They made that look simple yet we all know how hard it is. Congratulations SpaceX and Intelsat on a lovely launch.
Thank you to all at NSF, particularly our stalwart of all launches, no matter their origin, Steve P, for the brilliant coverage as always.
-
Congratulations to SpaceX Intelsat and everyone else involved on a successful launch!
Special thanks to Eastern Range for delaying planned maintenance to provide this launch window.
-
Barely 2nd half of the year and 10 launches already ! Yeehaw !
-
An expendable... how quaint... Congrats just the same to SpaceX and all the teams that worked the issue successfully, well done! Speaking of teams, thanks to the "NSF World" for providing the excellent coverage through all the attempts whether up here, across the pond or from down under! :)
-
Congratulations to SpaceX for finally breaking through the double digit barrier with a successful launch of Intelsat 35e! 10th launch of the year, hoping they get a lot more in before New Year's Eve. When Elon says he wants to get in 25-30 launches a year I no longer will doubt SpaceX can pull it off.
-
Congrats on the launch SpaceX! Always a shame to watch a perfectly good S1 go into the drink, here's to hoping there will be few to none of those to come.
-
Congrats to SpaceX on yet another successful launch. Glad it all worked out in the end. 3 launches in less than 2 weeks, not bad at all! :)
-
Congratulations to SpaceX, Intelsat, KSC, the Eastern Range, and anyone else I forgot. If at first you don't succeed, try, try again!
SpaceX launches are never boring to me. I'm always holding my breath until the payload is safely in orbit.
Is this a record for the fastest turnaround at 39A?
-
Congrats to SpaceX, Intelsat, and everyone else involved. Another picture perfect launch from LC-39A. :)

Fastest turnaround for SpaceX on the same pad at 12 days 4hrs 28mins 0secs from BulgariaSat to Intelsat35e... and a new record turnaround for SLC-39A, which has now broken its fastest turnaround time twice this year.
-
Congratulations to all involved!

Congrats to all involved. Really nice launch cadence. I am also going to go through withdrawals waiting for the next launch.

Congrats to SpaceX and all!
Rocket sure looked naked without recovery hardware, which is just the norm now, despite already launching a few like these this year.
Also thought it was nice how John pointed out and thanked on the webcast the eastern range for deferring their maintenance by a day to allow this launch before stand down.
Now it is going to be boring without any SpaceX launches for over a month. We are spoiled now.

Congrats Spacex
Great to see a steady approach with no launch fever.
Can't wait to see SpaceX back soon with 3 active pads....

This was supposed to be my first SpaceX launch observed directly, due to the last second scrub on Sunday I missed that opportunity but with many more launches coming I hope I will be able to do it again. Nonetheless, I am very happy they were successful on the third try!
Congrats to SpaceX, Eastern Range, Intelsat and everybody involved! Thank you NSF for great coverage and allowing me to follow the launch while traveling!
-
Excellent coverage as always, congrats to the folks at SpaceX that spent their holiday weekend working on a rocket in order to have a successful flight today. What a performance too, should make for one very happy customer.
-
Congrats to all at SpaceX, Intelsat and KSC on a successfull launch! Extra kudos to SpaceX on getting their YTD launch number into the double digits for the first time in the company's history. Keep up the good work, it's a pleasure to watch.
-
10 months ago Tory Bruno said, it typically takes 9 to 12 months for people to return to flight. I am really happy he was not right in this case, and that SpaceX launched 10 times in this time.
Congratulation!
-
any know the object of intelsat 35e ?
-
Thanks to Steven and the two Chrises (Chrisia? Chrisium?) for the excellent coverage as always.
Congratulations to SpaceX on this astounding pace.
Commiserations to Pad X.

Intelsat 35e Launches Successfully
Luxembourg, 5 July 2017 – Intelsat S.A. (NYSE: I), operator of the world’s first Globalized Network and leader in integrated satellite communications, announced the successful launch of the Intelsat 35e satellite, the fourth of the Intelsat EpicNG high throughput satellites. Intelsat 35e was launched from Cape Canaveral, Florida aboard a SpaceX Falcon 9 launch vehicle. Liftoff occurred at 7:38 pm EDT. The Intelsat 35e satellite separated from the rocket’s upper stage 32 minutes after launch, at 8:10 pm EDT, and signal acquisition has been confirmed.
Intelsat 35e launcher
Manufactured by Boeing and equipped with an advanced digital payload, Intelsat 35e will deliver high performance services in C- and Ku-band for wireless infrastructure, mobility, broadband, government and media customers in the Americas, the Caribbean, Europe and Africa. Intelsat 35e will be placed into service at 325.5° East where it replaces Intelsat 903, which will be redeployed to another Intelsat orbital location by year-end.
The Intelsat EpicNG fleet is designed to deliver more efficiency for satellite broadband service providers, providing improved performance and economics that allows customers to explore new applications and new business models to grow their businesses. Companies including Orange, INWI, Tele Greenland, Sonatel, Marlink, Speedcast, ETECSA and eProcess will be among the first to deploy services on the satellite once it is placed into service. Intelsat 35e also includes a tailored payload for direct-to-home (DTH) television services for Canal+, a leading provider of DTH services in the Caribbean.
“The successful launch of Intelsat 35e is a major milestone in our business plan for 2017, furthering the footprint and resilience of our Intelsat EpicNG infrastructure,” said Stephen Spengler, Chief Executive Officer, Intelsat. “With each Intelsat EpicNG launch, we advance our vision of creating a global, high performance for our customers that will unlock new growth opportunities in applications including mobility, wireless infrastructure and private data networks. As we further our innovations with respect to ground infrastructure and managed service offerings, like IntelsatOne Flex, we are transforming the role of satellite in the telecommunications landscape.”
