PLAYALINDA/KENNEDY SPACE CENTER, FL – SpaceX is targeting Saturday Oct. 7 for blastoff of the SES-11/EchoStar 105 commercial telecomsat following a successful static fire test of the first stage engines of the ‘used’ Falcon 9 booster, as a Florida Space Coast gator gazed on in wondrous glee as the engines fired away Monday afternoon, Oct. 2.
The brief engine test took place at 430 p.m. EDT (2030 GMT) Monday Oct. 2, with the sudden eruption of smoke and ash rushing out the north facing flame trench and into the air over historic pad 39A on NASA’s Kennedy Space Center during a windy and overcast afternoon – as I witnessed from the Playalinda Beach causeway FL with the jet black hungry gator just feet away from me in the inland waterways.
The static fire test lasted approximately three seconds. The test is routinely conducted by SpaceX engineers to confirm the rockets readiness to launch.
In this case the SpaceX Falcon 9 will refly and relaunch as a recycled rocket.
“Static fire test of Falcon 9 complete,” SpaceX confirmed via tweet soon after the hotfire test was conducted.
“Targeting October 7 launch of EchoStar 105/SES-11 from Pad 39A in Florida.”
The private SES-11/EchoStar 105 mission will launch on a ‘flight-proven’ booster and is slated for a dinnertime lift off on Oct. 7 at 6:53 p.m. EDT from seaside Launch Complex 39A at NASA’s Kennedy Space Center in Florida, carrying the SES-11 telecommunications payload.
SpaceX will also attempt to recover this booster again by soft landing on an ocean going platform prepositioned in the Atlantic Ocean- about 8 minutes after blastoff.
EchoStar 105/SES-11 is a high-powered hybrid Ku and C-band communications satellite launching as a dual-mission satellite for US-based operator EchoStar and Luxembourg-based operator SES.
It will be launched to geostationary orbit some 22,000 miles (36,000 kilometers) above the equator.
The EchoStar 105/SES-11 spacecraft was built by Airbus and shipped from the Airbus facilities in Toulouse, France to Cape Canaveral, FL for flight processing.
This is only the third recycled SpaceX Falcon 9 ever to be launched from Pad 39A.
SES was the first company to ever fly a payload on a ‘flight-proven’ Falcon 9. The SES-10 satellite lifted off successfully this spring on March 30, 2017.
The second reflown booster successfully launched the BulgariaSat-1 a few months later.
Pad 39A has been repurposed by SpaceX from its days as a NASA shuttle launch pad.
During Monday’s static fire test, the rocket’s first and second stages are fueled with liquid oxygen and RP-1 propellants like an actual launch, and a simulated countdown is carried out to the point of a brief engine ignition.
The hold down engine test with the erected rocket involved the ignition of all nine Merlin 1D first stage engines generating some 1.7 million pounds of thrust at pad 39A while the two stage rocket was restrained on the pad.
Playalinda Beach is a spectacular place to witness the launch from – while surfing the waves too – if you’re in the area.
However many favored launch viewing locations were decimated by the Irma’s wind and crashing waves and flooding – as I reported here earlier.
This launch is the first for SpaceX from KSC in the aftermath of Hurricane Irma which forced the center and Cape Canaveral Air Force Station to close several days and postponed this liftoff.
EchoStar 105/SES-11 provides EchoStar with 24 Ku-band transponders of 36 MHz, marketed as EchoStar 105, while it provides SES with a C-band payload of 24 transponders, marketed under the name SES-11, says SES. EchoStar 105/SES-11 replaces Ku-band capacity for AMC-15 and C-band capacity for AMC-18 at SES’ well-established 105 degrees West orbital slot.
SES-11 is the 47th satellite based on Airbus’s highly reliable Eurostar E3000 platform.
The engine test was carried out without the expensive payload attached to the top – a measured instituted since the catastrophic launch pad explosion and loss of the AMOS-6 commercial payload.
Following the hot fire test, the rocket is rolled back to the processing hangar located just outside the pad perimeter fence.
The 5,200 kg satellite will now be integrated with the rocket for the planned weekend liftoff.
The solar arrays generate a spacecraft power of 12 kW.
