<b>r/SpaceX Starlink-4 Official Launch Discussion & Updates Thread</b>
Welcome to the <a href="/r/SpaceX">r/SpaceX <em>StarlinkV1-L4</em> Official Launch Discussion & Updates Thread!<a href="/#%20MC%20//%20section%20intro">IntroductionWelcome, dear people of the subreddit! I'm <a href="/u/hitura-nobad">u/hitura-nobad, bringing you live updates on the StarlinkV1-L4 mission.OverviewStarlink-4 will launch the fourth batch of operational Starlink satellites into orbit aboard a Falcon 9 rocket. It will be the fifth Starlink mission overall. This launch is not expected to be similar to the <a href="/r/spacex/wiki/launches#wiki_80_.2013_starlink-3_.28v1.0.29">previous Starlink launch in late January, which saw 60 Starlink v1.0 satellites delivered to a single plane at a 290 km altitude. This time SpaceX is targeting a 386x212 km Orbit . 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:February 16, 15:25 UTC (10:25AM local)Backup dateFebruary 17, the launch time gets 21.5 minutes earlier each day.Static fire<a href="https://twitter.com/SpaceX/status/1228325869539610627">Completed February 14Payload60 Starlink version 1 satellitesPayload mass60 * 260 kg = 15 600 kgDeployment orbitLow Earth Orbit, 211 km x 386 km x 53° (<a href="/r/spacex/comments/ex0ilm/starlink4_launch_campaign_thread/fhihzt9/">expected)Operational orbitLow Earth Orbit, 550 km x 53°, 3 planesVehicleFalcon 9 v1.2 Block 5Core<a href="/r/SpaceX/wiki/cores#wiki_b1056">B1056Past flights of this core3 (CRS-17, CRS-18, JCSAT-18)Fairing catch attemptyes, both halvesLaunch site<a href="https://www.reddit.com/r/SpaceX/wiki/pads">SLC-40, Cape Canaveral Air Force Station, FloridaLandingOCISLY: 32.54722 N, 75.92306 W (628 km downrange)Mission success criteriaSuccessful separation & deployment of the Starlink Satellites.Previous and Pending Starlink MissionsMissionDate (UTC)CorePadDeployment OrbitNotes<a href="https://twitter.com/StarlinkUpdates">Sat Update1<a href="/r/spacex/wiki/launches#wiki_71_.2013_starlink_v0.9">Starlink v0.92019-05-241049.3SLC-40440km 53°60 test satellites with Ku band antennas<a href="https://twitter.com/StarlinkUpdates/status/1228695477610303490">Feb 152<a href="/r/spacex/wiki/launches#wiki_75_.2013_starlink-1_.28v1.0.29">Starlink-12019-11-111048.4SLC-40280km 53°60 version 1 satellites, v1.0 includes Ka band antennas<a href="https://twitter.com/StarlinkUpdates/status/1228695491371769861">Feb 153<a href="/r/spacex/wiki/launches#wiki_78_.2013_starlink-2_.28v1.0.29">Starlink-22020-01-071049.4SLC-40290km 53°60 version 1 satellites, 1 sat with experimental antireflective coating<a href="https://twitter.com/StarlinkUpdates/status/1228695506492252160">Feb 154<a href="/r/spacex/wiki/launches#wiki_80_.2013_starlink-3_.28v1.0.29">Starlink-32020-01-291051.3SLC-40290km 53°60 version 1 satellites<a href="https://twitter.com/StarlinkUpdates/status/1228695520396431361">Feb 155Starlink-4This Mission1056.4SLC-40212x386km 53°60 version 1 satellites expected-6<a href="/r/SpaceX/wiki/launches/manifest#wiki_upcoming_falcon_launches">Starlink-5MarchLC-39A60 version 1 satellites expected-7<a href="/r/SpaceX/wiki/launches/manifest#wiki_upcoming_falcon_launches">Starlink-6MarchSLC-40 / LC-39A60 version 1 satellites expected-Daily Starlink altitude updates on Twitter <a href="https://twitter.com/StarlinkUpdates">@StarlinkUpdatesScrub counterNone yetPayloadSpaceX designed Starlink to connect end users with low latency, high bandwidth broadband services by providing continual coverage around the world using a network of thousands of satellites in low Earth orbit.<em>Source: SpaceX</em>Stats&#9745;&#65039; 89th SpaceX launch&#9745;&#65039; 81st Falcon 9 launch&#9745;&#65039; 25th…

r/SpaceX Starlink-4 Recovery Discussion & Updates Thread
Hi! I'm u/Shahar603, and I'm hosting the recovery thread of the Starlink-4 mission.Booster RecoverySpaceX deployed OCISLY, GO Quest and Tug Hawk to carry out the booster recovery operation. B1056 has tragically failed to land on the droneship but it has performed a soft water landing and might be fished from the ocean (or destroyed like B1032).Fairing RecoveryUnfortunately both Ms. Tree and Ms. Chief have failed to catch the fairing halves. The ships might scoop the fairing halves from the ocean and bring them back to Port Canaveral.Current Recovery Fleet StatusVesselRoleStatusGO QuestDroneship support shipAt SeaTug HawkDroneship support shipSailing back to Port CanaveralGO Ms. TreeFairing RecoveryFollowing B1056GO Ms. ChiefFairing RecoveryFollowing B1056Live UpdatesTimeUpdate18 Feb 2020 08:00 UTCMs. Tree and Ms. Chief are following the floating booster17 Feb 2020 22:00 UTCMs. Tree and Ms. Chief have moved to the booster recovery area.
