The historic launch pad, famed for launching Apollo and Shuttle missions, performed well in its new role, with the post launch pad shakedown report noting only minor \u2013 and expected \u2013 damage from the nine Merlin 1D engines.<\/p>\nSpaceX is preparing to launch its second mission from KSC\u2019s Pad 39A, with the expendable Falcon 9 tasked with the EchoStar 23 mission conducting a Static Fire test on Thursday following an issue during Tuesday\u2019s attempt \u2013 ultimately slipping the launch date to March 14. Meanwhile, SLC-40 is preparing for a return to operations in August, in turn initiating the second phase of work on 39A for Falcon Heavy.<\/p>\n
Preparations for EchoStar 23:<\/p>\n
SpaceX debuted from 39A during the successful launch \u2013 and landing \u2013 of the Falcon 9 rocket that lofted the CRS-10 Dragon en route to the International Space Station (ISS).<\/p>\n
The historic launch pad, famed for launching Apollo and Shuttle missions, performed well in its new role, with the post launch pad shakedown report noting only minor \u2013 and expected \u2013 damage from the nine Merlin 1D engines.<\/p>\n
Per the L2 report, the damage was to hydraulic plumbing and wiring, which has since been repaired.<\/p>\n
Engineers have also added some additional blast protection to prevent future damage, aiding SpaceX\u2019s goal of an increased launch cadence as it works through a busy order book.<\/p>\n
That next launch on the schedule involves the EchoStar 23 geostationary satellite.<\/p>\n
The satellite was built by SSL, based on its 1300 bus. It is a flexible Ku-band satellite capable of being used from eight different orbital slots. It is expected to be initially used in a 45 degree slot over Brazil, with an operational lifetime of 15 years.<\/p>\n
The Static Fire test is effectively a full dress rehearsal ahead of launch day. The launch control team and the rocket \u2013 minus the payload \u2013 undergo the same flow as they will expect ahead of launch. This allows for a test of the major countdown items such as propellant loading and Ground Support Equipment (GSE) operations.<\/p>\n

A 3.5-second firing of the nine Merlin 1D engines highlights the test, which \u2013 among numerous other data points \u2013 provides information on engine ignition and shut down commands.<\/p>\n
The window for test lasts around six hours, which allows breathing space within the window for any unforeseen troubleshooting.<\/p>\n
The initial test window opened at 6 pm Eastern on Tuesday, with the target T-0 tracking 7:30 pm Eastern. However, 30 minutes into the window, an unspecified issue resulted in the test being delayed 24 and then 48 hours to allow for inspections. The T-0 for Thursday\u2019s firing was at the opening of the test window at 6 pm Eastern.<\/p>\n

Following the test, the rocket\u2019s propellant will be drained back ahead of the vehicle returning to the Horizontal Integration Facility (HIF) for payload mating.<\/p>\n
At the same time, SpaceX engineers will be conducting a data review into the test, which in turn feeds into the Launch Readiness Review (LRR) \u2013 at which point SpaceX officially sets the launch date.<\/p>\n
Due to the delays with the Static Fire test, SpaceX is now targeting a window that opens at 01:34 Eastern on March 14 and lasts for 2.5 hours. March 16 is the backup date. March 14 was the date for the Delta IV WGS-9 launch. ULA has yet to comment on the status of its launch schedule, the Delta IV will now move to the right on the schedule.<\/p>\n
The Falcon 9 involved with this launch is classed as expendable, meaning the Falcon 9 won\u2019t be returning for another spectacular landing at LZ-1 or on the Drone Ship. It will instead head for a watery grave in the Atlantic.<\/p>\n
SES-10:<\/p>\n
SpaceX has become a master of returning its first stages back home safely, with the next launch involving yet another milestone in its reusability aspirations. The mission to launch the SES-10 satellite will involve a Falcon 9 booster that previously launched and returned safely home for refurbishment.<\/p>\n
Falcon 9 Stage 1 (1021) was previously used to launch the CRS-8 Dragon to the International Space Station (ISS), before returning home for what was the first time a booster had successfully landed on the Drone Ship \u201cOf Course I Still Love You\u201d.<\/p>\n
![\"\"](\"\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2017\/03\/2017-03-07-163818-350x244.jpg\")
Following post launch safing and processing at Port Canaveral, the stage was housed in the HIF at 39A before taking a trip to Texas where it underwent a test firing program at SpaceX\u2019s McGregor facility early this year.<\/p>\n
Now back at the Kennedy Space Center, this returned Falcon 9 S1 is preparing for a March 27 launch date, although that date is currently tagged as \u201cUnder Review\u201d.<\/p>\n
SES-10 is a geostationary communications satellite to be operated by SES and was designed and manufactured by Airbus Defence and Space. The spacecraft is based on the Eurostar E3000 platform.<\/p>\n
Upcoming launches:<\/p>\n
With Falcon 9 stages in numerous locations, tracking which stage is becoming a major challenge for even the most ardent SpaceX follower.<\/p>\n
![\"\"](\"\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2017\/03\/2017-03-07-175045-350x234.jpg\")
Yet another Falcon 9 booster was being tested at McGregor just this week, believed to be 1034, as followed in L2\u2019s Falcon Stage Watch Section.<\/p>\n
With schedules subject to change, launch date placeholders \u2013 usually used to \u201cbook\u201d a slot on the Range \u2013 only provide a level of guidance to SpaceX\u2019s manifest plans.<\/p>\n
L2 Range information for both KSC and Vandenberg show two launches arranging dates in April from the East Coast, although this does not include the CRS-11 Dragon, with ISS sources claiming they are waiting on an updated launch schedule.<\/p>\n
On the West Coast, three missions have set placeholders for launch from Vandenberg, namely Iridium 2 on June 17, the Formosat-5 mission on July 22 and Iridium-3 on August 24.<\/p>\n
Pad Plans:<\/p>\n
SpaceX\u2019s successful debut of 39A returned its ability to launch missions from the East Coast, previously lost after SLC-40 was badly damaged when the Falcon 9 set to launch AMOS-6 was destroyed during a Static Fire anomaly.<\/p>\n
Engineers continue to repair the pad in preparation for what is currently classed \u2013 according to the latest source information \u2013 as a target of August for the return of its operational capability.<\/p>\n
![\"\"](\"\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2017\/03\/2017-03-07-171131-350x236.jpg\")
L2 information also notes that a new Transport\/Erector\/Launcher (TEL) will be installed on the pad, with the same design \u2013 albeit smaller \u2013 than the new TEL on 39A.<\/p>\n
It was also noted that SpaceX is working a plan that involves returning operations to SLC-40 before then working on 39A to prepare it for the maiden launch of the Falcon Heavy rocket.<\/p>\n
This work will take \u201cat least 60 days\u201d to complete, focusing on the 39A TEL table \u2013 which is currently specific to the single core Falcon 9 \u2013 and Tail Service Masts (TSM).<\/p>\n
Once the work is complete, SpaceX is expected to conduct a Wet Dress Rehearsal (WDR) for the Falcon Heavy \u2013 which will include two side boosters that have previously been involved with Falcon 9 missions.<\/p>\n
![\"\"](\"\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2017\/03\/2017-03-07-181804-350x228.jpg\")
The debut of the Falcon Heavy is not expected to take place until the latter part of the year and is currently believed to be without a specific payload.<\/p>\n
It is likely that the rocket will be launched with a mass simulator, allowing for a validation flight of the rocket ahead of its first full mission with the challenging US Air Force Space Test Program-2 (STP-2) flight profile.<\/p>\n
While SpaceX\u2019s immediate focus is with a series of Falcon 9 launches, the debut of Falcon Heavy will open up new mission potential, such as the recently announced private lunar flight involving the Dragon 2 spacecraft.<\/p>\n
