Liftoff of the previously-flown Falcon 9 rocket from NASA’s Kennedy Space Center with a European-built tv broadcast satellite has been pushed back from Saturday until at least next Wednesday evening, officials said.

The Falcon 9 launcher was likely to remove with the SES 11/EchoStar 105 communications satellite Saturday evening, Thursday that the mission would be postponed but two SES officials said.

An SES official acquainted with the launch campaign said liftoff from pad 39A was now expected no sooner than next Wed, Oct. 11, due to a potential technical concern on the rocket.

SpaceX hasn’t confirmed a good reason for the hold-off.

Built by Airbus Space and Defense, the 11 nearly,500-pound (5,200-kilogram) satellite possesses shared communications payload for SES and EchoStar.

In Sept 2014 SES and EchoStar announced their contract to build up the SES 11/EchoStar 105 satellite. The firms said the launch was expected by the finish of 2016 then.

EchoStar Satellite Services will use 24 Ku-band transponders aboard the satellite to replace digital network capacity the Colorado-based company currently leases on the AMC 15 satellite owned by SES. Because of its half of the new satellite, SES intends to use the craft’s C-band transponders for data and video distribution services.

The Falcon 9 rocket shall deploy the SES 11/EchoStar 105 satellite into an elliptical transfer orbit high above Globe, then your spacecraft’s onboard thruster shall steer it into a circular geostationary orbit along the equator.

The spacecraft shall start service hovering over 105 degrees west longitude, providing its antennas coverage on the Americas.

The slip will move the launch of SES 11/EchoStar 105 after a Falcon 9 flight from Vandenberg Air Pressure Foundation in California set for Mon, Oct. 9.

That objective, soaring with a newly-built Falcon 9 rocket, will add 10 more satellites to Iridium’s next-generation data and tone of voice relay fleet.

Arrangements for the Iridium launch from California’s Central Coast are proceeding on plan, Wednesday iridium said.

All 10 satellites, each about how big is a refrigerator, have been fueled and affixed with their two-tier mounting dispenser in readiness for encapsulation inside the Falcon 9’s payload shroud.

In the meantime, technicians prepared for a hold-down test-firing of the Falcon 9 rocket’s Merlin 1D main engines at Vandenberg’s Space Launch Organic 4-East when Thursday.

The static fire test for the SES 11/EchoStar 105 flight was completed Monday at the Kennedy Space Center in Florida.

The back-to-back launches will mark the 14th and 15th SpaceX flights this full year, the busiest flight rate in the past history of the California-based company led by billionaire Elon Musk.
