Elon Musk on Twitter: Dome to barrel weld made it to 7.1 bar, which is pretty good as ~6 bar is needed for orbital flight. With more precise parts & better welding conditions, we should reach ~8.5 bar, which is the 1.4 factor of safety needed for crewed flight.

About the ring around the second stage: at which point does it split up and into how many parts? This seems to vary quite a bit (Links to videos with timestamp inside)
It looks like the ring splits up into a varying number of parts and it also doesn't seem to happen at the same moment every time during the second stage sequence, compared to SES-1. Is that something that's predefined or does it happen randomly? Did the material change or the configuration?Here are the links to the timestamps for the official YouTube streams showing the ring separation for the 5 most recent launches:Jan 7, 2020 - Starlink MissionDec 16, 2019 - JCSAT-18/Kacific1 MissionDec 5, 2019 - CRS-19 MissionNov 11, 2019 - Starlink MissionAug 6, 2019 - AMOS-17 MISSION

<b>Starlink-3 Launch Campaign Thread</b>
<a href="https://pbs.twimg.com/media/D7TjU7DXkAAqtVZ.jpg"></a><a href="https://www.reddit.com/r/spacex/comments/eof5pr/starlink3_launch_campaign_thread/#siteTable_t3_eof5pr">JUMP TO COMMENTS</a>OverviewStarlink-3 (a.k.a. Starlink v1.0 Flight 3, Starlink Mission 4, etc.) will launch the third batch of Starlink version 1 satellites into orbit aboard a Falcon 9 rocket. It will be the fourth Starlink mission overall. This launch is expected to be similar to the <a href="/r/spacex/wiki/launches#wiki_78_.2013_starlink-2_.28v1.0.29">previous Starlink launch</a> in early January, which saw 60 Starlink v1.0 satellites delivered to a single plane at a 290 km altitude. Following launch the satellites will utilize their onboard ion thrusters to raise their orbits to 350 km. In the following weeks the satellites will take turns moving to the operational 550 km altitude in three groups of 20, making use of precession rates to separate themselves into three planes. Due to the high mass of several dozen satellites, the booster will land on a drone ship at a similar downrange distance to a GTO launch.Liftoff currently scheduled for:Late January TBDStatic fireTBDPayload60 Starlink version 1 satellitesPayload mass60 * 260 kg = 15 400 kg (presumed)Deployment orbitLow Earth Orbit, 290 km x 53° expectedOperational orbitLow Earth Orbit, 550 km x 53°, 3 planesVehicleFalcon 9 v1.2 Block 5CoreunknownPast flights of this coreunknownFairing reuseunknownFairing catch attemptLikelyLaunch site<a href="https://www.reddit.com/r/SpaceX/wiki/pads">SLC-40</a>, Cape Canaveral Air Force Station, FloridaLandingASDS: 32.54722 N, 75.92306 W (628 km downrange)Mission success criteriaSuccessful separation & deployment of the Starlink Satellites.Previous and Pending Starlink MissionsMissionDate (UTC)CoreDeployment OrbitNotesSat Update1<a href="/r/spacex/wiki/launches#wiki_71_.2013_starlink_v0.9">Starlink v0.9</a>2019-05-241049.3440km 53°60 test satellites with Ku band antennas<a href="https://twitter.com/planet4589/status/1216198537265975298">Jan 11</a>2<a href="/r/spacex/wiki/launches#wiki_75_.2013_starlink-1_.28v1.0.29">Starlink-1</a>2019-11-111048.4280km 53°60 version 1 satellites, v1.0 includes Ka band antennas<a href="https://twitter.com/planet4589/status/1216201828150513664">Jan 11</a>3<a href="/r/spacex/wiki/launches#wiki_78_.2013_starlink-2_.28v1.0.29">Starlink-2</a>2020-01-071049.4290km 53°60 version 1 satellites, 1 sat with experimental antireflective coating<a href="https://twitter.com/planet4589/status/1216204441306779649">Jan 11</a>4Starlink-3This Mission290km 53°60 version 1 satellites-5<a href="/r/SpaceX/wiki/launches/manifest#wiki_upcoming_falcon_launches">Starlink-4</a>Jan/Feb290km 53°60 version 1 satellites-Watching the LaunchSpaceX will host a live webcast on YouTube.

@elonmusk: Exactly. We’ve had good discussions with leading astronomers. One way or another, we’ll make sure Starlink doesn’t inhibit new discoveries or change the character of the night sky.
