PLAYALINDA BEACH/KENNEDY SPACE CENTER, FL – The path to an October launch trifecta from Florida’s Spaceport was cleared following SpaceX’s successful static fire test of the Falcon 9 boosters first stage engines this afternoon, Oct. 26, and thereby targeting Monday, Oct. 30 for blastoff of the KoreaSat-5A commercial telecomsat.

KoreaSat-5A is being launched by SpaceX under a commercial contract for South Korean operator KTSAT (a KT Corporation company) using a new first stage and will provide Direct to Home (DTH) broadcasting services.

If all goes well, the end of October KoreaSat-5A liftoff will count as the third rocket launch this month from the sunshine states increasingly busy Spaceport following two earlier launches carried out by both ULA and SpaceX.

Those two mid-month missions involved the commercial SES-11/EchoStar 105 UHDTV satellite on a SpaceX Falcon 9 and the covert NROL-52 spy satellite delivered to orbit on a ULA Atlas V respectively on Oct. 11 and Oct. 15.

The brief engine test of the two stage Falcon 9 took place at 12 noon EDT (1600 GMT) Thursday, Oct. 26, 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 very comfortably sunny and windy afternoon – as I witnessed from the crashing waves of Playalinda Beach, FL just a few miles away. See photo and video gallery from myself and space journalist colleague Jeff Seibert.

“Static fire test of Falcon 9 complete,” SpaceX confirmed via tweet soon after the hotfire test was conducted.

“Targeting October 30 launch of Koreasat-5A from Pad 39A in Florida.”

Monday’s mid-afternoon liftoff with the private KoreaSat-5A mission is targeted for a window that opens at 3:34 p.m. EDT (1934 GMT) from seaside Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

The launch window for the virgin booster extends nearly two and a half hours until 5:58 p.m. EDT (2158 GMT).

The SpaceX Falcon 9 will deliver Koreasat-5A to a geostationary transfer orbit (GTO).

SpaceX will also attempt to recover this booster by soft landing on an ocean going platform prepositioned in the Atlantic Ocean – about 8 minutes after blastoff.

Playalinda Beach is a spectacular place to witness the launch from – while surfing the waves too – if you’re in the area.

During today’s hold down 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 Falcon 9 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.

The static fire test lasted approximately three seconds. The test is routinely conducted by SpaceX engineers to confirm the rockets readiness to launch.

The engines exhaust cloud quickly dissipated within about a minute due to the high winds.

The engine test was run without the expensive payload on top to keep it safe in case of a launch pad accident as happened during a fueling test last September with the Israeli AMOS-6 payload.

The rocket will now be rolled back down the pad ramp and into the SpaceX processing hangar at the pad about ¼ mile away for integration with the Koreasat-5A spacecraft encapsulated inside the payload fairing.

In this case the SpaceX Falcon 9 will fly as a brand new rocket rather than a reused booster as happened earlier this month for the SES-11 launch.

The launch will be the 16th this year by a SpaceX Falcon 9 rocket.

Koreasat-5A was built by prime contractor, Thales Alenia Space, responsible for the design, production, testing and ground delivery. It arrived at the Florida launch base on Oct. 5 for integration with the Falcon 9 rocket.

The 3,700 kg satellite is equipped with 36 Ku-band transponders and based on Thales Alenia Space’s new-generation Spacebus 4000B2 platform. It will replace Koreasat 5.

The solar panels provide a payload power of approximately 6.5 kW. It will be positioned at 113° East and provide coverage for Indochina, Japan, Korea, the Philippines and the Middle East including Direct to Home (DTH) services.

Pad 39A has been repurposed by SpaceX from its days as a NASA shuttle launch pad.

To date SpaceX has accomplished 18 successful landings of a recovered Falcon 9 first stage booster by land and by sea.

The first stage from this months SES-11 launch arrived back into Port Canaveral, FL on top of the OCISLY droneship on Oct. 15.

PORT CANAVERAL/KENNEDY SPACE CENTER, FL – The now twice flown SpaceX first stage booster that successfully delivered the SES-11 UHDTV satellite to orbit at sunset Wednesday, Oct 11, sailed proudly back home into Port Canaveral during a beautiful Sunday sunrise, Oct. 15 only three days after it safely landed on a tiny droneship at sea.

The booster arrival also took place just hours after a ULA Atlas launched the covert NROL-52 surveillance satellite for the US National Reconnaissance Office (NRO) – making for a nonstop day of space action on the Florida Space Coast.

The 156-foot-tall Falcon 9 booster accomplished a precision guided rocket assisted touchdown on the football field sized OCISLY droneship platform about 8 minutes after the dinnertime liftoff with the private SES-11/EchoStar 105 communications satellite on Oct. 11 at 6:53 p.m. EDT from seaside Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

The 15 story tall first stage came to rest slightly tilted a few degrees, similar to at least two prior boosters that soft landed upright on OCISLY while prepositioned several hundred miles off shore of the Florida peninsula in the Atlantic Ocean.

The recycled booster was towed into Port Canaveral by a SpaceX contracted tugboat accompanied by a small fleet of pilot ships and support vessels.

The doubly used and doubly successful booster entered the mouth of Port Canaveral around 7:15 a.m. EDT Sunday under dawns delightful twilight I witnessed from Jetty Park and beach together with a few space media colleagues and a small crowd of onlookers with little fanfare.

Over the next hour it was hauled through the narrow channel as numerous vessels large and small and pleasure craft sailed by, likely wondering what they were looking it.

Finally the droneship platform was docked at SpaceX’s spot leased near the two huge shipping cranes dominating the scene across from popular portside restaurants – and also not far from humongous cruise ships dwarfing the booster in size.

The next step was for dock workers to hoist a cap and attach it to the top of the booster. This enabled it to eventually be carefully raised off the barge with a crane by about 1 p.m. and then slowly moved and swung over and affixed onto a restraining pedestal stand on land.

By the next evening Monday night, all 4 landing legs were still intact. After they are all detached the booster will be lowered horizontally aided by the cabling attached by the workers and placed on a flab bed transporter and trucked back to the Cape.

However the impact of developing and reusing ‘used’ rockets is leading to an era when re-flown rockets are offered as a ‘routine service’ rather than the exception.

Rocket reusability is at the heart of the extraordinary vision of billionaire entrepreneur and SpaceX CEO Elon Musk to drastically cut space launch costs and one day build a ‘City on Mars’.

And it represents a ‘major sea change getting closer’ to fruition with each passing day thanks to SpaceX, said SES CTO Martin Halliwell in an exclusive interview with Universe Today, following the stunning sunset blastoff of the SES-11 UHDTV commercial satellite on another ‘flight-proven’ Falcon 9 booster that also re-landed – thus completing another remarkable round of rocket recovery and recycling or ‘launch, land and relaunch!’

“As I’ve said before, I think in a couple years time you won’t even consider whether it’s a preflown rocket or a new rocket or a second time rocket,” SES Chief Technology Officer Martin Halliwell told Universe Today in a one-on-one post launch interview.

“It will just be a flight and you will buy a service to get to orbit – and that will be that!”

“It’s a major sea change,” Halliwell explained. “That’s absolutely true.”

“We’re getting closer to that every day. It’s exactly where we are going. There is no doubt about it.”

The launch of EchoStar 105/SES-11 counts as only the third recycled SpaceX Falcon 9 ever to be launched and is the third successful mission with a flight-proven orbital class rocket.

All three ‘flight-proven’ missions have lifted off from Pad 39A this year and all three have relanded.

The Falcon 9 first stage appeared to be in good shape upon its return to Port. I did not observe noticeable significant damage to the outside of the booster skin, grid fins or landing legs. Scorching seemed comparable to the first two reflown boosters.

This booster originally flew on the NASA Dragon CRS-10 resupply mission to the International Space Station in February of this year.

On arrival it was clearly anchored to the OCISLY droneship deck with multiple chains as previously done for droneship landings as well as with what appears to be several gripper arms.

OCISLY, which stands for “Of Course I Still Love You,” had departed Port Canaveral several days ahead of the Oct. 11 launch and was prepositioned in the Atlantic Ocean off the US East coast, just waiting for the boosters 2nd approach and pinpoint propulsive soft landing.

The booster was outfitted with four grid fins and four landing legs to accomplish the pinpoint touchdown on the barge at sea.

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.

NASA is also assessing whether to utilize a reflown booster on upcoming ISS resupply missions – starting with the next flight of the Dragon CRS-13 cargo ship which may liftoff as soon as early December.

Pad 39A has been repurposed by SpaceX from its days as a NASA shuttle launch pad.

KENNEDY SPACE CENTER, FL – Elon Musk’s extraordinary vision of an era when re-flown rockets are offered as a ‘routine service’ rather than the exception is a ‘major sea change getting closer’ to fruition with each passing day thanks to SpaceX, said SES CTO Martin Halliwell in an exclusive interview with Universe Today, following the stunning sunset blastoff of the SES-11 UHDTV commercial satellite on another ‘flight-proven’ Falcon 9 booster that also re-landed – thus completing another remarkable round of rocket recovery and recycling or ‘launch, land and relaunch!’

“As I’ve said before, I think in a couple years time you won’t even consider whether it’s a preflown rocket or a new rocket or a second time rocket,” SES Chief Technology Officer Martin Halliwell told Universe Today in a one-on-one post launch interview.

“The launch was fantastic,” Halliwell gushed. “Everything went perfectly. The countdown went perfectly, no hiccups, no drama, nothing whatsoever. So we were good to go!”

Plus its saving SES “months of time” and thereby “tens of millions of dollars of real money” to fly with a used booster rather than having their expensive satellite sit and languish uselessly on the ground.

SES-11 is primarily intended to significantly upgrade SES capabilities to transmit Ultra High Definition (UHD) TV signals or 4 K vs. standard HDTV – thereby pulling in more revenue streams.

SES made rocket history jointly with SpaceX earlier this year when they became the first company ever to agree to fly a payload on a recycled liquid fueled rocket that SpaceX’s billionaire CEO Elon Musk dubs ‘flight-proven’.

And Halliwell, as SES Chief Technology Officer, was instrumental in partnering with SpaceX CEO Musk to take a big leap make that happen.

The maiden ‘used’ Falcon 9 lifted off successfully with the SES-10 satellite and delivered the comsat to geostationary orbit on March 30, 2017 – in a monumental space achievement.

“This was our second reflown mission with SpaceX for SES-11. And we had a lot of discussion about it.”

“The more that we looked at it and the transparency we’ve gotten from SpaceX, working together with them we were convinced of the ‘flight worthiness’ of the Falcon 9 vehicle,” Halliwell told me.

SpaceX successfully delivered the 5.7 ton EchoStar 105/SES-11 joint mission satellite for SES and EchoStar to geostationary transfer orbit some 22,000 miles (36,000 kilometers) above the equator.

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.

How exactly does Halliwell and SES assess whether its worth taking a gamble on a ‘flight-proven’ booster to ensure it meets the high standards expected and really is robust and reliable and not end in disaster? How did the booster fare after the first reflown mission for SES-10?

Halliwell explained that SES employs a team of engineers embedded with SpaceX.

“We have US citizens who work embedded with SpaceX,” Halliwell replied. “They can understand and filter and react to that data they are exposed to and see what’s going on. And then determine if we are good to go or not.”

Why did SES decide on using a pre-flown booster?

“We sat down with SpaceX to see how the launch manifest and scheduling looks and asked whats the best way we can get SES-11 to orbit? Do we wait for new equipment or does SpaceX have preflown equipment that you can make available to us after refurbishment?”

“It came out that the fastest way we can get to orbit is by using a refurbished preflown vehicle. So we said OK we will go down that path. And that’s why we are here today.”

Did it save time or money for SES to go with a used booster?

“It saved us a few months. So we concentrated on the preflown booster after making that decision. For sure if we had chosen to use a new booster our SES-11 launch would have been somewhat later compared to launching today.”

So it turns out that SES got a faster trip to orbit for SES-11 and that in turn quickly translates into real money generated instead of more money wasted with a satellite parked somewhere in a storage shed for half a year of more. The actual savings on a launch was not that big.

“The average launch delay we have right now is about 7 months,” Halliwell explained.

“So we have the spacecraft already built and its ready, and ready to ship [to the launch site]. And then – we just wait! Until we have launch vehicle availability.”

“So think about it. I spent all my money on my spacecraft and most of my money on my launch vehicle. Plus a whole chunk of insurance money is already gone.”

“So I’m sitting there for 7 months. It’s just cash out and a very expensive wait!”

How much money does waiting around on the ground with a fully ready to launch spacecraft cost?

“That works out to tens of millions of dollars lost due to delays,” he replied. “Its real money. A ton of money!”

“Revenue we are not making. And paying for the money you spent. It’s gone !”

So with SES-11 now safely in orbit it will soon be generating revenue to recoup all the investments thus far accrued.

Is the era of reliable rocket reusability coming even sooner than some had expected?

“I think so certainly for SpaceX,” Halliwell responded.

“The other companies are all now running behind. You look towards Ariane with the reusable Prometheus and being cheaper – but there is a ways to go there. You look at Blue Origin and they are making progress. But they are not there yet.”

“Will Vulcan do this? I think everybody will consider this, and try to figure out the pros and cons of this and try to figure out an industrial model and a financial model, etc, etc.”

“Whether they go down that reusability path or not depends on whether it suits their business plan.”

“SpaceX has certainly taken a very, very difficult road. But they have come through it very well.”

Is SpaceX actually saving money? The company sunk huge sums of its own money amounting into the hundreds of millions of dollars to develop the reusability technology.

The advertised cost of a SpaceX launch is about $61 million.

Elon Musk routinely promotes the reusability technology as a means to drastically reduce space launch costs.

Thus SES CEO Karim Michel Sabbagh is looking for a reduction to about half that advertised price, in the neighborhood of $30 million.

To date Musk has only offered a marginal reduction to the contact price, citing the high development costs.

Musk has even joked that he should charge more for a reliable ‘flight-proven’ booster.

Halliwell says the real benefit thus far is the earlier launch date. SpaceX has a huge backlog of over 50 contracted launches that only grew longer following a pair of rocket explosions that forced launch delays while the firm investigated root causes.

What does Halliwell think is realistic regarding pricing and achieving the $30 million target?

“I’d love to see that,” Halliwell told me. “But I don’t think we’ll see that $30 million any time soon. Maybe it will stabilize in the mid $50 millions or $60 millions somewhere. I think that’s realistic.”

“I think we have to see how people like SpaceX work on their industrial/financial model.”

“To be honest, I think SpaceX themselves is trying to figure out where the pricing should be. How much is it really costing them? How much is the refurb costing them? How much are their ops costing?”

To date SpaceX has accomplished 18 successful landings of a recovered Falcon 9 first stage booster by land and by sea.

The first stage stands 156 feet tall.

KENNEDY SPACE CENTER, FL – SpaceX staged a stunning sunset blastoff this evening Oct. 11, of the commercial SES-11/EchoStar 105 HDTV satellite that will serve the everyday needs of millions of customers across North America as it soared to geostationary orbit on a recycled Falcon 9 from the Florida Space Coast.

Minutes later the now doubly ‘flight-proven’ booster safely made its way back to Cape Canaveral after reigniting its engines to carry out another upright soft landing and recovery – that potentially sets the stage for an unprecedented third launch.

The private SES-11/EchoStar 105 communications satellite mission made an on time liftoff of the recycled first stage booster at dinnertime Wednesday Oct. 11 at 6:53 p.m. EDT from seaside Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

SpaceX successfully delivered the nearly six ton EchoStar 105/SES-11 joint mission satellite for SES and ExchoStar to geostationary transfer orbit some 22,000 miles (36,000 kilometers) above the equator.

“Successful deployment of EchoStar 105/SES-11 to geostationary transfer orbit confirmed,” said SpaceX.

Remarkably today’s launch was the second launch for SpaceX this week following Monday’s Falcon 9 launch from Vandenberg AFB, Ca., carrying 10 Iridium-NEXT satellites to orbit – and a record setting 15th of 2017!

The launch, landing and satellite deployment were broadcast live on a SpaceX hosted webcast.

The weather was near perfect and there was scarcely a cloud in the sky. Space enthusiasts who traveled far and wide from around the globe to witness a launch were richly rewarded with time and money well spent.

That’s in stark contrast to the horrible weather conditions existing just days ago that forced a part of weather scrubs for the ULA Atlas V. Launch of the NROL-52 spy satellite is currently rescheduled for Sat., Oct 14.

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.

The used two stage 229-foot-tall (70-meter) Falcon 9 rocket was rolled out to pad 39A Tuesday to ready it for today’s liftoff.

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.

The satellite was successfully deployed as planned approximately 36 minutes after liftoff.

“SES-11 is a high-powered communications satellite designed to especially accelerate the development of the US video neighbourhood, and the delivery of HD and UHD channels. Optimised for digital television delivery, SES-11 joins SES-1 and SES-3 at the centre of its robust North American orbital arc, which reaches more than 100 million TV homes. Together with SES-1 and SES-3, SES-11 will be utilised for the expansion of the North America Ultra HD platform,” according to SES.

“SES-11 offers comprehensive coverage over North America, including Hawaii, Mexico and the Caribbean, and will also empower businesses and governments to capture new opportunities and expand their reach across the region.”

The 5,200 kg (11,500 pounds) satellite was encapsulated inside the payload fairing and integrated with the Falcon 9 rocket.

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.

After the 156 foot tall first stage booster completed its primary mission task, SpaceX engineers guided it to a second landing on the tiny football field sized OCISLY drone ship for a soft touchdown some eight and a half minutes after liftoff.

“Falcon 9 first stage has landed on Of Course I Still Love You — third successful mission with a flight-proven orbital class rocket,” said SpaceX.

This marked the 18th successful landing of a recovered Falcon 9 first stage booster.

This booster originally flew on the NASA Dragon CRS-10 resupply mission to the International Space Station in February of this year.

OCISLY or “Of Course I Still Love You” left Port Canaveral several days ahead of the planned Oct. 11 launch and was prepositioned in the Atlantic Ocean some 400 miles (600 km) off the US East coast, just waiting for the boosters 2nd approach and pinpoint propulsive soft landing.

The booster was outfitted with four grid fins and four landing legs to accomplish the pinpoint touchdown on the barge at sea.

KENNEDY SPACE CENTER, FL – SpaceX is all set for a sunset blastoff Wednesday, Oct. 11 of the commercial SES-11/EchoStar 105 Ultra High Definition (UHD) TV satellite serving North America on a ‘used’ Falcon 9 booster from the Florida Space Coast – that is also targeted to re-land a second time on an sea going platform off shore in the Atlantic.

Spectators should enjoy a spectacular view of the SpaceX Falcon 9 dinnertime launch with a forecast of extremely favorable weather conditions. This comes on the heels of multiple deluges of torrential rain that twice scrubbed last week’s launch of a United Launch Alliance V carrying a USAF spy satellite.

The private SES-11/EchoStar 105 communications satellite mission will launch on a ‘flight-proven’ booster and is slated for a dinnertime liftoff on Oct. 11 at 6:53 p.m. EDT from seaside Launch Complex 39A at NASA’s Kennedy Space Center in Florida, carrying the SES-11.

All systems are GO at L Minus 1 Day!

“#EchoStar105 is targeted for launch Oct. 11 from launch Complex 39A at NASA’s Kennedy Space Center in Florida-launch window 6:53-8:53 PM EDT,” EchoStar tweeted today.

“Getting Echostar-105/#SES11 ready for launch!” SES tweeted further.

If all goes well this will be the second launch for SpaceX this week following Monday’s Falcon 9 launch from Vandenberg AFB, Ca carrying 10 Iridium-NEXT satellites to orbit – and a record setting 15th of 2017!

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.

The used two stage 229-foot-tall (70-meter) Falcon 9 rocket was rolled out to pad 39A today, erected to vertical launch position and is now poised for liftoff Wednesday.

It will launch the two and a half ton EchoStar 105/SES-11 to geostationary orbit some 22,000 miles (36,000 kilometers) above the equator.

SpaceX will also attempt to recover this recycled Falcon 9 first stage booster again by soft landing on a droneship platform prepositioned hundreds of miles off shore in the Atlantic Ocean – some 8 minutes after blastoff.

Spectacular weather is expected Wednesday for space enthusiasts gathering in local regional hotels after traveling here from across the globe.

Playalinda Beach is among the best places to witness the launch from – while surfing the waves too – if you’re in the area.

You can watch the launch live on a SpaceX dedicated webcast starting about 10 minutes prior to the 6:53 pm EDT or 10:53 pm UTC liftoff time.

Watch the SpaceX broadcast live at: SpaceX.com/webcast

The two hour long launch window closes at 8:53 p.m. EDT.

The weather outlook is currently exceptional along the Florida Space Coast with a 90% chance of favorable conditions at launch time according to U.S. Air Force meteorologists with the 45th Space Wing Weather Squadron at Patrick Air Force Base. The primary concerns on Oct. 11 are only for Cumulus Clouds.

The odds remain high at 90% favorable for the 24 hour scrub turnaround day on Oct. 12.

The 45th Space Wing forecast is also favorable for the landing recovery area through Thursday “when a low pressure system may move into the area, increasing winds and seas. This low will migrate west and possibly impact Florida by the weekend.”

After the 156 foot tall first stage booster complets its primary mission task, SpaceX engineers seek to guide it to a second landing on the tiny OCISLY drone ship for a soft touchdown some eight and a half minutes after liftoff.

OCISLY or “Of Course I Still Love You” left Port Canaveral several days ahead of the planned Oct. 11 launch and is prepositioned in the Atlantic Ocean some 400 miles (600 km) off the US East coast, just waiting for the boosters 2nd approach and pinpoint propulsive soft landing.

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.

The satellite is scheduled to be deployed approximately 36 minutes after liftoff.

“SES-11 is a high-powered communications satellite designed to especially accelerate the development of the US video neighbourhood, and the delivery of HD and UHD channels. Optimised for digital television delivery, SES-11 joins SES-1 and SES-3 at the centre of its robust North American orbital arc, which reaches more than 100 million TV homes. Together with SES-1 and SES-3, SES-11 will be utilised for the expansion of the North America Ultra HD platform,” according to SES.

“SES-11 offers comprehensive coverage over North America, including Hawaii, Mexico and the Caribbean, and will also empower businesses and governments to capture new opportunities and expand their reach across the region.”

The path to launch was cleared following last weeks successful static fire test of the first stage engines Falcon 9.

During the Oct. 2 static fire test, the rocket’s first and second stages were fueled with liquid oxygen and RP-1 propellants like an actual launch, and a simulated countdown was 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 – minus the expensive payload.

Following the hot fire test, the rocket was rolled back to the processing hangar located just outside the pad perimeter fence.

The 5,200 kg (11,500 pounds) satellite encapsulated inside the payload fairing was then integrated with the Falcon 9 rocket.

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.”

Playalinda Beach is a spectacular place to witness the launch from – while surfing the waves too – if you’re in the area.

The Beach survived Hurricane Irma but suffered serious erosion.

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.
