A commercial communications satellite set for launch fr om Florida's Space Coast on a SpaceX Falcon 9 rocket to beam broadband and television signals across the Asia-Pacific region will remain on Earth until at least Sunday night, 24 hours later than previously scheduled.

The Telstar 18 VANTAGE satellite, also known as APSTAR 5C, was supposed to launch atop a brand new Falcon 9 rocket Saturday night. The high-power telecom craft, built by SSL in Palo Alto, California, weighs around 15,564 pounds (7,060 kilograms) and is set to begin a 15-year mission for Telesat and APT Satellite, based in Canada and Hong Kong, respectively.

But officials decided to delay the launch, according to Gerald Nagler, a Telesat spokesperson. Nagler did not provide a new target launch date, but the website for Patrick Air Force Base, headquarters of the U.S. Air Force's 45th Space Wing, was updated late Thursday to show the mission is scheduled for liftoff Sunday, Sept. 9.

The four-hour launch window would open at 11:28 p.m. EDT Sunday (0328 GMT Monday).

A SpaceX spokesperson Thursday would not confirm a reason for the launch postponement — or even if the mission has been delayed — in response to questions fr om Spaceflight Now. SpaceX tweeted Wednesday to confirm that the flight was — at that time — scheduled to take off Saturday.

Marine tracking websites Thursday showed SpaceX's rocket landing platform continuing toward the recovery zone for the Falcon 9's first stage booster in the Atlantic Ocean east of Cape Canaveral. SpaceX plans to retrieve the first stage for reuse on a future mission.

The launch of the Telstar 18 VANTAGE/APSTAR 5C satellite will be SpaceX's 16th mission of the year — including launches from Florida and California — and the 16th launch from Cape Canaveral overall in 2018.

SpaceX test-fired the Falcon 9's first stage engines at Cape Canaveral's Complex 40 launch pad Wednesday, then lowered the rocket for rollback to a nearby hangar, wh ere technicians planned to attach the Telstar 18 VANTAGE/APSTAR 5C spacecraft to the launcher.

The satellite will provide C-band and Ku-band communications services across the Asia-Pacific region from a perch in geostationary orbit nearly 22,300 miles (35,800 kilometers) over the equator.

The new satellite will launch into an elliptical transfer orbit aboard the Falcon 9, then use its on-board thruster to climb into a circular orbit, wh ere its orbital velocity will match the rate of Earth's rotation at 138 degrees east longitude.

Once Telstar 18 VANTAGE arrives at its operating post, it will beam high-throughput signals to serve direct-to-home broadcast, video distribution, maritime, and other telecom markets. Carrying a combination of broad regional beams and high-bandwidth spot beams, the satellite's coverage area will span from India and Pakistan in the west, to Hawaii in the east.

APT Satellite of Hong Kong — also known as APSTAR — paid for 57.5 percent of the mission's cost in exchange for use of the same percentage of the satellite's communications capacity.

A high-throughput communications satellite developed as a joint venture between Telesat and APT Satellite is set to ride a SpaceX Falcon 9 rocket into orbit Sunday night from Cape Canaveral.

The commercial telecom station, designated Telstar 18 VANTAGE or APSTAR 5C, is awaiting launch at 11:28 p.m. EDT Sunday (0328 GMT Monday), at the opening of a four-hour launch window.

SpaceX plans to roll the 229-foot-tall (70-meter) Falcon 9 rocket out of its hangar some time today, then erect the launcher vertical atop Cape Canaveral's Complex 40 launch pad in preparation for this evening's countdown.

Officials delayed the launch from Saturday to allow additional time to complete pre-launch checkouts, SpaceX said.

Built by SSL in Palo Alto, California, the Telstar 18 VANTAGE/APSTAR 5C satellite weighs more than 15,560 pounds (7,060 kilograms) at launch. It's heading for a perch in geostationary orbit over the equator at 138 degrees east longitude to provide broadband, television and cellular backhaul services across the Asia-Pacific region for Telesat and APT Satellite.

SpaceX plans to recover the first stage of the Falcon 9 rocket aboard the company's drone ship "Of Course I Still Love You" a few hundred miles east of Cape Canaveral in the Atlantic Ocean. Engineers hope to inspect, refurbish and re-fly the booster on a future mission.

September 9, 2018 | Stephen Clark

SpaceX's Falcon 9 rocket is set for liftoff from Cape Canaveral on Monday, heading due east over the Atlantic Ocean to deliver the Telstar 18 VANTAGE communications satellite into orbit around 32 minutes later.

The 229-foot-tall (70-meter) rocket is poised for launch from pad 40 at Cape Canaveral Air Force Station in Florida at 11:28 p.m. EDT Sunday (0328 GMT Monday) at the opening of a four-hour launch window.

Perched atop the rocket is the Telstar 18 VANTAGE communications satellite, a spacecraft manufactured by SSL — formerly known as Space Systems/Loral — and owned by Ottawa-based Telesat in partnership with APT Satellite of Hong Kong.

Telstar 18 VANTAGE weighs 15,564 pounds (7,060 kilograms) with its propellant tanks fully loaded, making it one of the heaviest commercial communications satellites ever launched, just shy of a record set in July with the launch of the Telstar 19 VANTAGE spacecraft on a previous Falcon 9 rocket.

After deployment from the upper stage of the Falcon 9 rocket in an elliptical transfer orbit, Telstar 18 VANTAGE will use its on-board hydrazine-fueled engine and electric thrusters to boost itself into a circular geostationary orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator.

The U.S.-built, Canadian-owned satellite will beam C-band and Ku-band broadband services over the Asia-Pacific region.

Once Telstar 18 VANTAGE arrives at its operating post, it will beam high-throughput signals to serve direct-to-home broadcast, video distribution, maritime, and other telecom markets. Carrying a combination of broad regional beams and high-bandwidth spot beams, the satellite's coverage area will span from India and Pakistan in the west, to Hawaii in the east.

APT Satellite — also known as APSTAR — paid for 57.5 percent of the mission's cost in exchange for use of the same percentage of the satellite's communications capacity.

The Falcon 9 rocket launching Telstar 18 VANTAGE will fly in the upgraded "Block 5" configuration, with a brand new first stage booster.

The timeline below outlines the launch sequence for the Falcon 9 flight with Telstar 18 VANTAGE.

Data source: SpaceX

T-0:00:00: Liftoff


After the rocket's nine Merlin engines pass an automated health check, hold-down clamps will release the Falcon 9 booster for liftoff from pad 40.

T+0:01:00: Mach 1


The Falcon 9 rocket reaches Mach 1, the speed of sound, as the nine Merlin 1D engines provide more than 1.7 million pounds of thrust.

T+0:01:07: Max Q


The Falcon 9 rocket reaches Max Q, the point of maximum aerodynamic pressure.

T+0:02:33: MECO


The Falcon 9's nine Merlin 1D engines shut down.

T+0:02:37: Stage 1 Separation


The Falcon 9's first stage separates from the second stage moments after MECO.

T+0:02:45: First Ignition of Second Stage


The second stage Merlin 1D vacuum engine ignites for a six-minute burn to put the rocket and Telstar 18 VANTAGE into a preliminary parking orbit.

T+0:03:29: Fairing Jettison


The 5.2-meter (17.1-foot) diameter payload fairing jettisons once the Falcon 9 rocket ascends through the dense lower atmosphere. The 43-foot-tall fairing is made of two clamshell-like halves composed of carbon fiber with an aluminum honeycomb core.

T+0:06:17: Stage 1 Entry Burn


A subset of the first stage's Merlin 1D engines ignite for an entry burn to slow down for landing. A final landing burn will occur just before touchdown.

T+0:08:14: SECO 1


The second stage of the Falcon 9 rocket shuts down after reaching a preliminary low-altitude orbit. The upper stage and Telstar 18 VANTAGE begin a coast phase scheduled to last more than 18 minutes before the second stage Merlin vacuum engine reignites.

T+0:08:32: Stage 1 Landing


The Falcon 9 rocket's first stage booster touches down on SpaceX's drone ship in the Atlantic Ocean.

T+0:26:17: Second Ignition of Second Stage


The Falcon 9's second stage Merlin engine restarts to propel the Telstar 18 VANTAGE communications satellite into an elliptical transfer orbit.

T+0:27:00: SECO 2


The Merlin engine shuts down after a short burn to put the Telstar 18 VANTAGE satellite in the proper elliptical orbit for deployment.

T+0:32:01: Telstar 19 VANTAGE Separation


The Telstar 18 VANTAGE satellite separates from the Falcon 9 rocket into an elliptical transfer orbit, on the way to a perch in geostationary orbit.
