CAPE CANAVERAL AIR FORCE STATION, FL - A spectacular midnight launch lit up Florida Space Coast skies Monday, June 4, as the massive six ton SES-12 high powered commercial telecommunications satellite that will provide ever better TV, internet and more to ground, airplane and cruise ship services for millions of customers - soared to orbit on a recycled SpaceX Falcon 9 rocket.


SES-12 will serve over 18 million customers across the globe all the way from the Middle East to the vast Asia-Pacific region for Luxembourg-based operator SES.


The ‘Flight-Proven’ Falcon 9 roared off seaside Space Launch Complex-40 just past midnight Monday morning June 4 at 12:45 a.m. EDT (0445 GMT) from Cape Canaveral Air Force Station, Florida.

SES maintains a fleet of space-based satellites in a constellation comprising more than 70 spacecraft in a variety of orbits.

Today’s launch comes after a four day delay announced last Thursday when SpaceX said engineers needed to run “run additional tests” on the workhorse Falcon 9 vehicles second stage to verify its readiness to launch.

This Falcon 9 rocket was comprised of a unique combination of old and new involving a ‘Flight-Proven’ Block 4 first stage and a new and improved Block 5 upper stage. The first stage is expendable and was not recovered.


The launch vehicle utilized a recycled first stage booster from the OTV-5 mission launch in September 2017.

The middle-of-the-night lift off of the 229-foot tall (70-meter) Falcon 9 proved to be absolutely stunning and flawlessly delivered SES-12 to its preliminary supersynchronous transfer orbit.

The satellite is functioning perfectly. It was right on the money,” SES Chief Technology Officer (CTO) Martin Halliwell told me in an exclusive post-launch interview with SpaceUpClose.

“The SpaceX team is amazing. They worked right through the weekend and at night to clear all the issues that came up with the second stage that allowed us to launch. At SpaceX Headquarters in Hawthrone, CA, they worked to make sure all the testing criteria were achieved. There were no outstanding issues by launch time but it took a lot of time to clear them all.”

“The Falcon 9 delivered SES-12 to an Apogee of approximately 58,000 km and perigee was 294 km.”

Spectators enjoyed the magnificent sky show as the threatening sunshine state skies that have inundated Florida with drenching rains storms and lightning all week long miraculously parted in time of the early morning launch.

We could easily see the rocket for more than 4 minutes as it blastoff off in an easterly direction over the Atlantic Ocean, accelerated to orbit and soon arced over to African continent.

The nine Merlin-9 engines ignited to generate over 1.7 million pounds of liftoff thrust fueled by super chilled liquid oxygen and RP-1 propellants stored inside the used first stage booster.



The upper stage fired as planned and spacecraft separation took place right on time about 32 minutes after liftoff.

SES-12 will provide a vast  array of services including HDTV and UHDTV, wifi, banking,  cruise ships and public services.

“More content. More immersive viewing experience. Blazing internet speeds. Reliable cell coverage. All of these dynamic customer requirements can now be met with the successful launch of SES-12, which will provide incremental high performance capacity and offer greater reliability and flexibility to our customers,” says Halliwell.

SES-12 is gigantic – think school bus sized. And it just barely fits inside the nose cone,  Halliwell told me.

“Despite the size SES-12 survived the launch well and there were no issues.”

“SES-12 is the most powerful spacecraft ever built for us,” said Halliwell. ‘It’s really, really big.”

“Its like 2 satellites in one common bus supporting 6 wide beams and 72 high throughput data beams.”

SES-12 weighs 5383 kg and measure 3.5 m x 3.5 m x 8 m. 



SpaceX did not attempt to recover the first stage booster on the OCISLY droneship, said Halliwell.  OCISLY is normally prepositioned at sea in the Atlantic Ocean some 400 miles (600 km) off the east coast of Florida for ocean landings. OCISLY has remained docked in Port Canaveral.





Rather the 15 story tall booster “is expandable and will be “sent straight into the ocean.”





“There will be no recovery and there are no landing legs.”




“We've actually stripped everything off the first stage, so there are no landing legs on board," Halliwell noted.

"This is going straight into the ocean. The first stage is a Block 4 and the upper stage is a Block 5.  We get a lot of performance from this vehicle." 

SES-12 was built by prime contractor Airbus Defence and Space and was originally designed to operate for 15 years in geostationary orbit.

But the life time will be extended about 7 years from 15 to 22 years by firing the second stage engine for 2 to 5 seconds longer

“It will come into service for us in January or February 2019.”

“SES-12 is our 6th satellite launch by SpaceX.”

The Falcon 9 rocket is comprised of a unique combination of old and new involving a ‘Flight-Proven’ Block 4 first stage and a new and improved Block 5 upper stage.

The upgraded Block 5 Falcon 9 just successfully flew its maiden flight last month for the Bangabandhu-1 comsat for Bangladesh on May 11.

SES-12 will be co-located with SES-8 at the 95 degrees East orbital slot. Combined they will serve to reach over 18 million SES video, data and TV customers across the Asia-Pacific region. It will replace and augment services currently provided on NSS-6.

The path to launch was cleared last week when SpaceX engineers conducted a successful hold down static fire test of the rocket at the pad, minus the payload, wherein the two stages were fueled with propellants completing a full countdown simulation.

During the dress rehearsal all 9 Merlin 1D first stage engines are ignited to full thrust for several seconds while the rocket is held down at the pad.

The SES-12 mission marked SpaceX’s 11th launch of 2018.

The next SpaceX launch involves the Dragon CRS-15 cargo resupply mission to the International Space Station (ISS) – tentatively set for liftoff on no earlier than June 28 from Space launch Complex-40 at the Cape.
