Until mid November, the Starship development teams have been focusing on finishing the Mark 1 and 2 vehicles which were expected to make <a href="https://twitter.com/elonmusk/status/1166860032052539392">suborbital test flights</a>. The Mark 1 testing campaign ended on November 20 with a <a href="https://youtu.be/3nTSubYzQOM">catastrophic failure</a> of the methane tank during pressurized testing. In <a href="https://twitter.com/thesheetztweetz/status/1197306617760559104">a statement from SpaceX</a> after the incident it was announced that the decision had already been made not to fly these vehicles, and that development will now focus on the orbital Mark 3 design.Launch mounts for the Starship prototypes are in the works. Starhopper's Texas launch site <a href="https://twitter.com/austinbarnard45/status/1174819747705368576">was modified</a> to handle Starship Mk.1, and at Kennedy Space Center's LC-39A, a dedicated <a href="https://forum.nasaspaceflight.com/index.php?topic=48720.0">Starship launch platform and landing pad are under construction</a>. SpaceX has not recently indicated what sort of flight test schedule to expect from Mark 3.Starship is powered by SpaceX's <a href="https://twitter.com/SpaceX/status/1178128488697618432">Raptor</a>, a full flow staged combustion cycle methane/oxygen rocket engine. Sub-scale Raptor test firing began in 2016, and full-scale test firing began early 2019 at McGregor, Texas, where there are <a href="https://www.nasaspaceflight.com/2019/10/spacex-renovating-falcon-stand-mcgregor/">two operational test stands, and a third is under construction</a>. Eventually, Starship will have <a href="https://twitter.com/elonmusk/status/1131433322276483072">three sea level Raptors and three vacuum Raptors</a>. Super Heavy may initially use around <a href="https://twitter.com/elonmusk/status/1131625229367693312">20 Raptors</a>, and operational versions could have around 31 to 37 sea level Raptors.Previous Threads:<a href="https://redd.it/am4gxw/">Starhopper Thread</a> #1 (2019-02-01) A dramatic venting watertower<a href="https://redd.it/bi08h9/">Starhopper Thread</a> #2 (2019-04-27) Hops and hiccups - Starships never come alone<a href="https://redd.it/c61lqs/">Starhopper Thread</a> #3 (2019-06-27) RCS and SN6 - 20 meter hopping<a href="https://redd.it/ci70t4/">Starhopper Thread</a> #4 (2019-07-26) 150 meter hop and Mk.1 and Mk.2 protoype growth<a href="https://redd.it/cv8vi4/">Starhopper 150m Hop</a> (2019-08-27) Updates and discussion<a href="https://redd.it/cxyt8x/">Starship Dev Thread</a> #5 (2019-08-31) Mk.1 fins and temporary assembly<a href="https://redd.it/d9l5bm/">Starship Presentation Updates Thread</a> (2019-09-27) Updates and discussion - <a href="https://youtu.be/sOpMrVnjYeY">Webcast</a><a href="http://redd.it/dfd8ik/">Starship Dev Thread</a> #6 (2019-10-09) Mk.1 partial reassembly and bulkhead liberationVehicle UpdatesStarship Mk.2 at Cocoa, Florida — Construction and Updates2019-11-23<a href="https://youtu.be/80tZcbVTKjo">Transport cradles on site</a> (<em>YouTube</em>), unclear if Mk.2 will use them2019-11-18<a href="https://twitter.com/John_Winkopp/status/11964595…

SpaceX closing down Cocoa construction site, will delay Mk4
The YouTube channel "What About It" just posted a Patreon preview. I cannot provide a link at this time. Has an inside source who revealed SpaceX laid off 80% of the Cocoa workers, will be doing no more construction there. Will construct the new facility at Roberts Road on Kennedy Space Center and then start Mk4. The layoff indicates the gap before Mk4 fabrication will be fairly long, by SpaceX standards. This does not bode well for Mk 2, but there is no word on any possible use. Vid contains more news about the ring welders, etc. Appears SpaceX is taking a more measured approach with Mk4 while proceeding quickly with Mk3. Multiple activities going on at Boca Chica simultaneously, as usual.No intention of posting rumor or speculation. This channel is professionally done and their source has proved to be reliable. The vid will be up on YT Monday morning EDT, or possibly very late Sunday. Not trying to promo them, but the Cocoa site closing is hot news.

SpaceX’s Jessica Jensen explains why the SpX-19 launch will perform a drone ship landing vs. returning to the Cape: need extra performance from 1st stage because 2nd stage will do a “thermal demonstration” in orbit after deployment with a six-hour coast.

Let me know in the comments if you have information, updates and corrections to add. Thanks!Mission OverviewJCSAT-18 is a mobile broadband communications payload built for Sky Perfect JSAT Corporation of Japan and will service Asia Pacific. Kacific1 is a high throughput broadband internet payload built for Kacific Broadband Satellites and will service certain high demand areas of Southeast Asia and the Pacific. Both payloads share a single chassis.SpaceX will launch the Boeing built dual payload satellite to geostationary transfer orbit from SLC-40 at Cape Canaveral AFS on a Falcon 9, and the first-stage booster is expected to land downrange on the OCISLY droneship.This is SpaceX's <strong>13th</strong> mission of 2019, its <strong>6th</strong> commercial flight of the year and the <strong>77th</strong> Falcon 9 launch overall.
