the secretive Zuma payload to Low Earth Orbit next Wednesday. &nbsp;The static fire occurred at the opening of the window at the Kennedy Space Center at 18:00 EST (23:00 UTC). &nbsp;Meanwhile, a Merlin 1D test stand failure at McGregor, Texas, poses no issue to SpaceX\u2019s ongoing acceptance testing of the Block 5 Merlin 1D engine or to the company\u2019s launch manifest.<\/p>\n<p><b>Static Fire:<\/b><\/p>\n<p>As is always the case in the days leading to a scheduled launch, SpaceX&nbsp;static fires their Falcon 9 rocket, with this one working towards the launch of the Zuma payload next Wednesday. <\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"size-medium wp-image-53015 alignleft\"

stages were mated together in the Horizontal Integration Facility (HIF) just outside the pad perimeter gate of LC-39A at the Kennedy Space Center before the entire rocket was then mated to the Transporter\/Erector\/Launcher (TEL) and reaction frame.<\/p>\n<p>The Falcon 9 in question is first stage booster B1043, a brand new Falcon 9 first stage that was originally intended for use on NASA\u2019s upcoming contracted CRS-13\/Dragon mission to the ISS \u2013 set to launch NET (No Earlier Than) 4 December 2017 from the newly rebuilt SLC-40 on the Cape Canaveral Air Force Station.<\/p>\n<p>As first reported by NASASpaceflight.com, however, core B1043 was reassigned to Zuma when the secretive mission took immediate priority on SpaceX\u2019s November manifest with an absolute, contract-specified need to launch No Later Than 30 November 2017.<\/p>\n<h4 class=\"widget-title penci-border-arrow\">See Also<\/h4>\n<ul>\n<li>F9 Zuma UPDATES<\/li>\n<li>SpaceX&nbsp;Missions Forum Section<\/li>\n<li>L2 SpaceX Section<\/li>\n<li>Click here to Join L2<\/li>\n<\/ul>\n<p>With NASA understood to be switching CRS-13 and CRS-14 to flight-proven boosters that have flown only one prior LEO (Low Earth Orbit) mission, this cleared up any conflict with B1043 being transferred to Zuma.<\/p>\n<p>(NOTE: NASA has not publically announced the approval of flight proven Falcon 9 boosters for CRS missions, but sources insist a positive decision has been made.)<\/p>\n<p>     (adsbygoogle = window.adsbygoogle || []).push({});<\/p>\n<p>For Saturday\u2019s static fire, Falcon 9 was transported to the launch pad and erected over the flame trench of Pad 39A, where it was then connected to all electrical, data, and propellant loading equipment.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-53018 alignleft\"

countdown \u2013 complete with full propellant loading of RP-1 kerosene and LOX (liquid oxygen) into both the first and second stages of the Falcon 9 and lighting of all nine Merlin 1D engines for approximately 3.5 seconds while keeping the hold down clamps firmly attached to the rocket.<\/p>\n<p>Once the static fire was complete, the engines were shut down and the vehicle placed into a safe configuration before detanking, afterwhich Falcon 9 and the TEL will be lowered to horizontal and taken back into the HIF where the rocket will be mated with its secret payload.<\/p>\n<p>At the same time, engineers will review all data from the static fire \u2013 which will be used at the L-2 Launch Readiness Review (LRR) to clear Falcon 9 for flight.<\/p>\n<p>Liftoff of Falcon 9 with Zuma is currently set for Wednesday, 15 November 2017 in a two hour launch window from 20:00-22:00 EST \u2013 01:00-03:00 UTC on 16 November.<\/p>\n<p><b>Engine test stand failure at McGregor:<\/b><\/p>\n<p>The static fire comes one week after a failure of a Merlin 1D test stand at SpaceX\u2019s McGregor, Texas, facility.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-medium wp-image-53032\" src=\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2017\/11\/NSF_20171111_171118-350x267.jpg\" alt=\"\" width=\"350\" height=\"267\">Importantly, the failure is not significant and was not a failure of an engine but rather of the associated test stand Ground Support Equipment (GSE). <\/p>\n<p>According to sources, the failure occurred ahead of an engine firing, which involved&nbsp;a Merlin 1D Block 5 qualification unit.<\/p>\n<p>&nbsp;<\/p>\n<p>As the investigation continues, SpaceX is in the process of repairing the test stand \u2013 a repair timeline that is expected to result in the stand being back online in a couple weeks.<\/p>\n<p>Moreover, a co-located second Merlin 1D test stand is understood to have only received minor damage at best, with its repairs only taking a few days. <\/p>\n<p>Also quite important is the fact that this was a ground and test stand issue and not an engine failure similar to other failures on the test stand \u2013 which means there is no effect on the SpaceX manifest that has established a steady cadence and rhythm to its launches this year.<\/p>\n<p>As of writing, SpaceX\u2019s end of year manifest still has three Falcon 9 missions and one Falcon Heavy mission, with a manifest as

&nbsp;This core will attempt an ASDS, Just Read The Instructions, drone ship landing after launch.<\/p>\n<p>Then, if the Falcon Heavy schedule holds, the most powerful rocket in the world will debut on approx. NET 29 December \u2013 with its two flight proven side-mounted boosters (B1023.2 [Thaicom-8 in May 2016] and B1025.2 [CRS-9 in July 2016]) performing simultaneous RTLS landings side-by-side at LZ-1 while its center, brand new core \u2013 B1033 \u2013 performs an ASDS drone ship landing on Of Course I Still Love You in the Atlantic moments later.<\/p>\n<p>(Images: SpaceX, Chris Gebhardt for NASASpaceflight.com, and L2.
