<b>r/SpaceX official CRS-18 Release, Deorbit and Recovery Thread</b>
<a href="/#%20MC%20//%20section%20intro"></a>Welcome to the <a href="/r/SpaceX">r/SpaceX</a> official CRS-18 Release, Deorbit and Recovery ThreadI'm <a href="/u/Hitura-nobad">u/Hitura-nobad</a> hosting the release and recovery of the CRS-18 Dragon spacecraft!<a href="/#%20MC%20//%20section%20events"></a>TimelineTimeUpdate<a href="/#%20MC%20//%20row%200"></a> T-2d 0hThread going live<a href="/#%20MC%20//%20section%20viewing"></a>About The RecoverySpaceX is going to conclude the CRS-18 Cargo Dragon mission to the International Space Station on August 27th with the Deorbit and Recovery of this spacecraft. Dragon will splash down in the Pacific Ocean approximately 482 km southwest of Los Angeles. The west coast dragon recovery ship NRC Quest will be waiting at the landing zone to pick dragon up and bring it back to the harbor.<a href="/#%20MC%20//%20section%20stats"></a>Payloads on Dragon C108.3<a href="https://www.nasa.gov/press-release/nasa-tv-to-air-us-cargo-ship-departure-from-space-station">Source: NASA</a><strong>Bio-Mining in Microgravity</strong>The <a href="https://www.nasa.gov/mission_pages/station/research/experiments/explorer/Investigation.html?#id=7566">Biorock</a> investigation provides insight into the physical interactions of liquid, rocks and microorganisms in microgravity and improving the efficiency and understanding of mining materials in space. Bio-mining eventually could help explorers on the Moon or Mars get needed materials on site, lessening the need for precious resources from Earth and reducing the amount of supplies explorers must take with them.<strong>Mechanisms of Moss in Microgravity</strong><a href="https://www.nasa.gov/mission_pages/station/research/experiments/explorer/Investigation.html?#id=7892">Space Moss</a> compares mosses grown aboard the space station with those grown on Earth to determine how microgravity affects its growth, development, and other characteristics. Tiny plants without roots, mosses need only a small area for growth, an advantage for their potential use in space and future bases on the Moon or Mars. This investigation also could yield information that aids in engineering other plants to grow better on the Moon and Mars, as well as on Earth.<strong>Improving Tire Manufacturing from Orbit</strong>The <a href="https://www.nasa.gov/mission_pages/station/research/experiments/explorer/Investigation.html?#id=7716">Goodyear Tire</a> investigation uses microgravity to push the limits of silica fillers for tire applications. A better understanding of silica morphology and the relationship between silica structure and its properties could provide improvements for increased fuel efficiency, which would reduce transportation costs and help to protect Earth’s environment.<a href="/#%20MC%20//%20section%20mission"></a>Current Recovery FleetVesselRoleStatus<a href="https://www.spacexfleet.com/nrc-quest">NRC Quest</a>Dragon Recovery ShipOn route to the recovery zone<a href="/#%20MC%20//%20section%20landing"></a>Recovery TimelineTime (Approximate)Event27 August, 14:15 UTCstart of NASA-TV coverage for the release27 August, 14:42 UTCRelease from the SSRMS (Robotic Arm)27 August, 19:22 UTCDeorbit Burn (No Video Coverage)27 August, 20:21 UTCSplashdown (No Video Coverage)<a href="/#%20MC%20//%20section%20resources"></a>Links & Resources<a href="https://www.marinetraffic.com">MarineTraffic</a> - Useful when ships are closer to land!<a href="https://www.google.com/maps/d/viewer?hl=en&mid=17sTdDuaLN-EJeuALqkvhM2hULM5lvIKZ&ll=32.12289698742197%2C-121.25001614999996&z=8">Recovery Zone Map</a> - Thanks to <a href="/u/Raul74Cz">u/Raul74Cz</a><a href="https://twitter.com/SpaceXFleet">SpaceXFleet Updates</a> - Twitter Updates!<a href="https://www.spacexfleet.com/">SpaceXFleet.com</a> - SpaceXFleet Information!<a href="/#%20MC%20//%20section%20participate"></a>Participate in the discussion!Please post small launch updates, discussions, and…
<b>Starhopper 200m Hop Official Discussion & Updates Thread!</b>
<a href="/#%20MC%20//%20section%20intro"></a>About the MissionHello, I'm <a href="/u/ModeHopper">u/ModeHopper</a> and tomorrow is hop day (hopefully)! I will be your host for this, the third SpaceX hop of 2019. If you have updates or resources that you think should be added to this post the most immediate way to contact me is on Twitter @HopperMode, alternatively you can leave them in the comments below and I will check back periodically in the lead up to the launch.OverviewFor this launch SpaceX will attempt it's second untethered hop of the prototype launch vehicle colloquially known as <em>Starhopper</em> from their Boca Chica facility in Texas. The vehicle is expected to ascend using it's single Raptor engine to an altitude of 200m before performing a controlled landing. The primary aim of the mission is to test the flight dynamics of both the vehicle and the Raptor engine to better inform decisions concerning their next generation launch vehicle <em>Starship</em>. Previously, Starhopper performed a short tethered hop and a 20m untethered hop - this will be the final flight for the vehicle before it is retired and superseded by the Mk.1 and Mk.2 orbital prototype Starships under construction in Boca Chica (Tx.) and Cocoa (Fl.).SchedulePrimary launch window opens: <strong>Monday, August 26 at 21:00 UTC (16:00 CDT).</strong>Primary launch window closes: <strong>Monday, August 26 at 21:15 UTC (16:15 CDT).</strong>Scrub Counter<strong>0</strong> Scrubs &#129310;Facts and Stats3rd hop of the Starhopper vehicle.2nd untethered hop of the Starhopper vehicle.6th production Raptor engine ever made.This will be the longest duration flight of a Raptor engine to date.Launch VehicleTypeNameLocationFirst stage"Starhopper" Test UnitSpaceX Boca Chica, TexasSecond stageN/AN/A    Live UpdatesMission StateCurrently GO for launch, expected at 21:00 UTC on Monday August 26<a href="/#%20MC%20//%20section%20events"></a>TimelineTimeUpdate<a href="/#%20MC%20//%20row%200"></a> T-1d 4hThread goes live<a href="/#%20MC%20//%20section%20viewing"></a>Launch SitePlaceLocationCoordinates &#127760;Sunrise &#127749;Sunset &#127751;Time zone &#8986;Launch site<a href="https://en.wikipedia.org/wiki/SpaceX_South_Texas_Launch_Site">SpaceX South Texas Launch Site</a><a href="https://tools.wmflabs.org/geohack/geohack.php?pagename=SpaceX_South_Texas_Launch_Site&params=25.997_N_97.157_W_">25° 59′ N, 97° 9′ W</a>07:0719:56UTC-5Landing site<a href="https://en.wikipedia.org/wiki/SpaceX_South_Texas_Launch_Site">SpaceX South Texas Landing Pad</a><a href="https://tools.wmflabs.org/geohack/geohack.php?pagename=SpaceX_South_Texas_Launch_Site&params=25.997_N_97.157_W_">25° 59′ N, 97° 9′ W</a>07:0719:56UTC-5Weather - Boca Chica, Tx. 1 2Launch windowWeatherTemperatureWindProb. of rainVisibilityUV IndexProb. of weather scrubPrimary launch window&#127780;&#65039; <em>Partly Cloudy</em>&#127777;&#65039; <em>33°C (91°F)</em>&#127788;&#65039; <em>19 mph SSE</em>&#128167; <em>10%</em>&#128064; <em>8 mi</em><em>Extreme</em>&#128721; <em>Very Low</em>Sources: 1. <a href="https://weather.com/weather/today/l/14f156cf3bef21428476e88a245155c0af9eac08534e25960539154a8f2cef7b">www.weather.com</a> 2. <a href="https://forecast.weather.gov/MapClick.php?lat=25.995480000000043&lon=-97.16547999999995#.XWKiyfx7mUk">NOAA</a><a href="/#%20MC%20//%20section%20stats"></a>    Watch &#128308; LIVEYouTube &#128250;LinkNote<a href="https://www.youtube.com/watch?v=cn5j_E2CcqE">South Padre Island Streamt</a>Live 24/7<a href="https://www.spadre.com/default.htm">South Padre Island Stream - direct</a>Live 24/7<a href="https://www.youtube.com/watch?v=kqZDeKHDwb4">LabPadre Stream</a>Live 24/7<a href="https://www.youtube.com/channel/UC6uKrU_WqJ1R2HMTY3LIx5Q">Everyday Astronaut - livestream</a>Not yet liveRelays &#128225;TBA<a href="/#%20MC%20//%20section%20mission"></a>    Useful ResourcesEssentialsLinkSource<a href="https://twitter.com/BocaChicaGal

150 Meter Starhopper Test
SpaceX’s Starhopper prototype has completed its second and final flight test, lifting off to an apogee of roughly 150m (500 ft) before nailing the bullseye on a landing pad adjacent to the launch mount.
