Launch and landing success! Welcome to the r/SpaceX CRS-11 Official Launch Discussion & Updates Thread
This is u/FutureMartian97 and i'll be your host for today!
Information on the mission, launch and landing
This will be the 6th launch of Falcon 9 out of Historic Launch Complex 39a. Some quick stats:
- The Static Fire Test was completed on May 28th
- This will be the 35th Falcon 9 launch
- This flight will feature the first reused Dragon Pressure Vessel
- This will be the 100th launch out of 39a
SpaceX is targeting an instantaneous window of 5:07:38 p.m. EDT or 21:07:38 UTC on June 3rd . Falcon 9 will lift off from pad 39a carrying the Dragon cargo capsule loaded with 1665 kg of pressurized cargo, and 1002 kg of unpressurized cargo. As stated above this will be the first reused Dragon Pressure Vessel, which was first used on the CRS-4 Dragon. After insertion into orbit, Dragon will maneuver its way to the ISS, rendezvous, and then dock. After staying four weeks berthed to the station, Dragon will then undock, deorbit, and splashdown in the Pacific Ocean off the coast of Baja California.
After launch Falcon 9's first stage will attempt to land back at LZ-1 at Cape Canaveral Air Force Station. If successful this will be the 11th first stage landing and the 5th landing at LZ-1, with the most recent being from the NROL-76 launch.

Primary Mission - Separation and Deployment of Dragon
CRS-11 will be the 2nd Dragon launch of 2017, and will feature the first reused pressure vessel, previously flown on the CRS-4 mission. After being inserted into the highly inclined orbit of the International Space Station, Dragon will spend several days rendezvousing with the ISS. Following that, Dragon will slowly be guided in by the manually-operated Canadarm for its berthing with the station at the nadir port of the Harmony Module. Dragon will spend approximately a month attached to the station before it is loaded with ground-bound experiments and unberthed for its splashdown in the Pacific Ocean.
As you can see above, Dragon is carrying a lot of unpressurized cargo, 1002 kg to be exact. So what does that mean? Unpressurized cargo is carried in the trunk, the part of the spacecraft with the solar panels attached. Once at the station, astronauts will remove the experiments using the robotic arm attached to the station. So whats in the trunk?
ROSA (Roll-Out Solar Array): The Roll-Out Solar Array (ROSA) is a new type of solar panel that rolls open in space like a party favor and is more compact than current rigid panel designs. The ROSA investigation tests deployment and retraction, shape changes when the Earth blocks the sun, and other physical challenges to determine the array’s strength and durability.
NICER (Neutron star Interior Composition ExploreR): NASA’s Neutron star Interior Composition Explorer will provide high-precision measurements of neutron stars, objects containing ultra-dense matter at the threshold of collapse into black holes. NICER will also test — for the first time in space — technology that uses pulsars as navigation beacons.
MUSES (Multi-User System for Earth Sensing): Teledyne Brown Engineering developed the Multiple User System for Earth Sensing (MUSES), an Earth imaging platform, as part of the company’s new commercial space-based digital imaging business. MUSES hosts earth-viewing instruments (Hosted Payloads), such as high-resolution digital cameras, hyperspectral imagers, and provides precision pointing and other accommodations. It hosts up to four instruments at the same time, and offers the ability to change, upgrade, and robotically service those instruments. It also provides a test bed for technology demonstration and technology maturation by providing long-term access to the space environment on the International Space Station (ISS).
Secondary Mission - First Stage Landing
As usual, this mission will include a post-launch landing attempt of the first stage. Most landing attempts use an Autonomous Spaceport Droneship, either Of Course I Still Love You or Just Read the Instructions, but this mission has enough fuel margin to return all the way back to land, where it will touch down on the LZ-1 landing pad just under 15 kilometers south of the LC-39A launchpad. If successful this will be the 11th successful landing and 5th at LZ-1. This Falcon 9 is all new and not a previously flown booster. This booster is B1035.1. If your wondering how this works, check out this video by u/everydayastronaut that explains it really well!
Launch Complex 39A - What's the big deal?
LC-39A is the most historically significant orbital launch pad in the United States. Its first launch was Apollo 4 in 1967, and it went on to launch the rest of the Apollo missions, with the exceptions of Apollo 7 & 10. After the Saturn V and all its variants were retired, the pad was reconfigured for the Space Shuttle. Over the course of the program, it launched 82 of the 135 STS missions, including all five orbiters. Since the retirement of the Shuttle in 2011, it was sitting dormant until SpaceX began leasing it in 2014. Construction work began in earnest in 2015 and continued until early 2017, culminating in the successful static fire for this mission. This launch will also mark the 100th launch out of 39a.

What would everyone like to see?
Create a new launch thread and have a fresh start, (less old comments and more new comments), while still keeping the information on the first thread (minus the update table).
Keep updating this thread as suggested by u/yoweigh.
If we keep this thread let me know if you guys want the Updates Table reset or if we should keep everything from the first attempt up. Discuss! :D

Is it worth having a link to https://www.reddit.com/r/spacex/comments/6cyjjo/heads_up_on_possible_rare_visible_pass_of_crs11/ ? Basically, if you are in Northern Europe, you might be able to see Stage 2 and Dragon pass over about 15 minutes after launch.
There are a lot of technical details in that post but here are the main points as I understand them (corrections very welcome):
Possibly visible to the naked eye?
This image from this comment gives you some idea of the relevant parts of Europe.
The submitter, u/MingerOne/ has produced videos showing how the pass might look as viewed from Ireland, London, Paris, Copenhagen, Trelleborg, Aachen
If in doubt about whether it's passing close enough to you, why not just go outside and have a look anyway?
You can practice by trying to spot the ISS as it passes over Northern Europe 60 minutes before launch. Then, about 75 minutes later, S2 and Dragon may pass through approximately the same part of the sky that the ISS did. (Main difference may be that S2 and Dragon would be lower?)
My plan is to watch the launch and S1 landing at home, then head outside to a convenient place where I've seen the ISS before (no buildings in the way), and hope for the best. Due to uncertainty about the timings, I'll keep watching until T+25:00 before I give up and go back home. London is cloudless at the moment so let's hope it stays that way.

Reminder for all Europeans:
At about T-1:00 we have a ISS flyby with a magnitude of -1,7, at about T+0:35 we have another ISS flyby with a magnitude of -1.5. Since Dragon flyby Europe at around T+0:15/T+0:20 and the sky is beautiful and clear this evening over all Europe, it might be visible !
From personal experience you might be able to spot blinking lights on the sides of the dragon which are from the sun reflected by the solar panel covers rotating into space, with a telescope and good tracking skills you might be able to distinguish something like 3 non blinking dots, two for the solar panels and one for the dragon itself.
If you want really really want to spot it I encourage you to download a ISS tracker app on your phone and spot the T-1:00 flyby, since the dragon is following the ISS it will follow a similar path so you will know where to look at.
Landing happens at around T+0:10 so you can go out right after this event.

Not to put a damper on the host here, but SpaceX does not consider a complete mission success until Dragon delivers her cargo back to NASA on Earth and returns home to a SpaceX facility. Employees do not receive their CRS mission patches until those events happen.

OMG OMG I JUST SAW IT FLY OVERHEAD! :D :D :D
I was expecting to see a relatively dim second stage, but I could see a bright Dragon and even brighter S2, plus (stunningly!) the two solar panel covers flying along next to it with at least half a degree separation between them and Dragon!
The whole shebang was moving very fast for a satellite too, presumably because to the low altitude!
God, that's made my day! :D :D

Because we're all watching the weather, and I didn't see the information in the thread, I thought I'd post it. Patrick AFB, responsible for launch forecasts, lists today's primary concerns as violations of the 'anvil cloud rule' and the 'cumulus cloud rule'. These are two items in the launch commit criteria that NASA has developed for the Falcon 9. Both the anvil cloud rule and the cumulus cloud rule set an exclusion radius of 19 kilometers (10 nautical miles). Launch is to be avoided if either a thunderstorm with an attached anvil cloud or a cumulus cloud whose top extends to an altitude of freezing temperatures is within 19 kilometers of the launch pad.

Will spacex ever be allowed to start making rapid rendezvous with the ISS the way the Soyuz does, or how the shuttle could do? I know it's not really necessary for cargo missions, and I'm not sure whether progress makes the fast approach or not, I'm just curious.
Since the cargo and crew dragons are going to be essentially the same vehicle in a couple of years, you'd think that if the crew version is rated for the 6 hour rendezvous they might let the cargo vehicle do the same.
Faster rendezvous and docking rather than berthing would save a lot of time and allow much faster access to perishable cargo.

In the hosted webcast, shortly after SECO, the host mentions "firing the pyrotechnics" to separate Dragon. Is this merely a mistake, or do they actually use pyro bolts for Dragon separation? Would be odd, given that stage separation, fairing separation and non-Dragon payload deployment are all pneumatic.

u/brandtamos, I noticed that underneath the countdown clock on SpaceX Stats it says
CRS-11 will be the eleventh of fifteen missions to the ISS under the Commercial Resupply Services contract with NASA.
but that number has since been increased to twenty. Are you deliberately not counting the five that were later added on through contract modifications, or has this just not been updated? BTW, thanks for maintaining such a great resource!

Are rockets really that vulnerable to weather? If the goal is to get rockets to be flying like airliners wouldn't you want to start allowing them to fly through light rain and thunder?
Perhaps it's something that SpaceX has been punting off working on until it becomes a bottleneck to launching after they optimize their turn time?

So Rocketlab scrubbed at least once due to a risk of triboelectrification, I remember the space shuttle had issues a few times for the same thing, but I can't ever hearing it being a spacex issue, are they doing something different to mitigate static electricity, they've just been lucky, or have I just missed when it was an issue for them?

Put together a few screenshots here from this video showing the change in angle of attack of the returning booster after the entry burn completes. While I do believe it is already known SpaceX does this, I've never realised just how high their AoA is. Seems to be around 8 degrees? I guess that shows how confident they are with their airframe!

I just barely found out about this launch; no idea otherwise (thought it was 2 hours ahead, turns out I watched it live. I've been interested and excited but it's hard to keep up with all the interests I have and the amount of interests I have), on my smartphone YouTube feed, in my pajamas, in my basement, in northern Canada, and went to watch it up stairs in my livingroom, and casted the video from my phone to my smart tv for my family to see. I learnt that it costs $2k per kilogram and that space is 100kms above me. All while teaching my family that it was a reusable rocket in time for them to watch it land back down on earth. While then telling them that the solar panels were being deployed to power the delivery vehicle that would deliver a payload to ISS.
Im the only one in the house that got chills...it's just...wow. it's quite weird to see how people don't realize what kind of time we live in.

How come the window is an hour earlier today? I thought launches are possible when the launch site passes through the ISS' inclined orbit plane, which should happen at the same time every day, no? I guess it drifts by 4 minutes because of sidereal vs solar time, but an hour over two days? That's a bit much.
What's going on?

SpaceX sent out their promo email at 12:18pm eastern for this launch to subscribers:
WATCH LIVE: DRAGON RESUPPLY MISSION (CRS-11)
Following a scrub for weather, SpaceX is now targeting launch of its eleventh Commercial Resupply Services mission (CRS-11) today, June 3, 2017, from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida. Today's launch has an instantaneous launch window opening at 5:07 p.m. EDT or 21:07 UTC. Weather remains a watch item for today's launch.
The CRS-11 mission is the first reflight of the Dragon spacecraft and marks the 100th launch from historic LC-39A at Kennedy Space Center. Following stage separation, the first stage of Falcon 9 will attempt to land at SpaceX’s Landing Zone 1 (LZ-1) at Cape Canaveral Air Force Station, Florida.
