ЦитироватьSES agrees to launch another satellite on a previously-flown Falcon 9 booster
August 4, 2017 Stephen Clark

Six months after sending one of its communications satellites to orbit on the first re-flight of a SpaceX rocket, SES intends to launch a hybrid television broadcasting satellite owned in partnership with EchoStar on another previously-used Falcon 9 rocket from Florida's Space Coast as soon as late September, industry officials told Spaceflight Now.

The launch of the SES 11 spacecraft, also named EchoStar 105, will be the third time SpaceX has sent a customer's satellite into orbit with the help of a reused rocket stage. Industry officials said SES, EchoStar and SpaceX agreed in recent weeks to shift the satellite from an all-new rocket to one with a previously-flown first stage.

The SES 11/EchoStar 105 satellite will likely ride a Falcon 9 first stage that first flew Feb. 19 with a Dragon supply ship heading for the International Space Station, one source said, but a firm assignment has not been confirmed. That vehicle returned to a vertical touchdown at Landing Zone 1 at Cape Canaveral Air Force Station

Liftoff from a Florida launch pad is scheduled no sooner than around Sept. 27, a couple of days after a United Launch Alliance Atlas 5 rocket is set to haul a classified payload into orbit for the National Reconnaissance Office, the U.S. government's spy satellite agency. The Atlas 5 flight with a U.S. national security mission is already booked on the Air Force's Eastern Range for Sept. 25, and will receive priority to launch first if it remains on schedule.

SES and EchoStar announced their agreement to develop the SES 11/EchoStar 105 satellite in September 2014. The companies then said the launch was expected by the end of 2016.

EchoStar Satellite Services will employ 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. For its half of the new satellite, SES intends to operate the craft's C-band transponders for video and data distribution services.

Airbus Defense and Space built the satellite, which will be shipped to Cape Canaveral in the coming weeks from its final assembly plant in Toulouse, France.

SpaceX has not said which launch pad it will use for the the SES 11/EchoStar 105 mission.

The company's Falcon 9 launches from Florida so far this year have lifted off at pad 39A at NASA's Kennedy Space Center, but SpaceX plans to move its Falcon 9 base to nearby pad 40 later this year once crews complete repairs and reactivate the complex after a rocket explosion last year. SpaceX officials have not set a firm timetable for the move to pad 40, which will free up pad 39A for final preparations to launch the first Falcon Heavy rocket, a demonstration flight set for November.

The SES 11/EchoStar 105 satellite will weigh approximately 11,900 pounds (5,400 kilograms) at launch. A payload of that mass means SpaceX will likely try to land the Falcon 9's first stage on a platform downrange from Cape Canaveral in the Atlantic Ocean.

Спойлер
SpaceX has launched two missions with re-flown first stage boosters — both successful.

The SES 10 satellite rode the first reused Falcon 9 rocket March 30 from Kennedy Space Center, and the BulgariaSat 1 communications satellite was the passenger for the second Falcon 9 booster re-flight June 23.

SpaceX says reusing pieces of its Falcon 9 rockets reduces launch costs, and engineers aim to reduce the time needed between flights of the same booster from months to days, and perhaps as little as 24 hours, an aspiration espoused by Elon Musk, the company's chief executive.

The SES 11/EchoStar 105 mission is third in line on SpaceX's Florida launch schedule, following the Aug. 13 liftoff of a space station resupply flight and the Sept. 7 launch of the Air Force's X-37B spaceplane, a reusable robotic vehicle used to conduct secret experiments in orbit. The Falcon 9s on both launches will be all-new.

Meanwhile, a SpaceX team at Vandenberg Air Force Base in California is preparing for an Aug. 24 Falcon 9 launch with the Taiwanese Formosat 5 Earth observation satellite and a Sept. 30 liftoff with the third set of 10 next-generation Iridium voice and data replay spacecraft.

SES currently has two more satellites booked to launch on SpaceX Falcon 9 rockets after SES 11/EchoStar 105.

Martin Halliwell, chief technology officer at SES, said earlier this year that those two spacecraft — SES 14 and SES 16, the latter of which was developed in partnership with the government of Luxembourg — could also fly on previously-launched Falcon 9 boosters. Halliwell said then that SES 11/EchoStar 105 would likely fly on a new Falcon 9, but those plans changed.

SES 16, also named GovSat 1, could launch in the fourth quarter of this year, SES said in a quarterly earnings presentation last week. SES 14's launch has been delayed to early 2018 due to SpaceX's jam-packed manifest, which Musk said last month includes up to a dozen more missions this year.

Another SES satellite, SES 14, is assigned to launch on a European Ariane 5 rocket from French Guiana in early 2018.

ЦитироватьThat incident heavily damaged the SLC-40 pad, especially below ground level as burning propellant from the deceased rocket drained into the base structures. That pad is close to returning to action, with the latest information citing the potential return for the SES-11 mission at the end of September.

WASHINGTON — SpaceX intends to launch EchoStar-105/SES-11 on a partially reused Falcon 9 rocket no earlier than October, the company said Aug. 31.
Спойлер
The mission will be SpaceX's third launch to use a previously flown Falcon 9 booster. The first was the March launch of SES-10 followed by the June launch of BulgariaSat-1.

Luxembourg-based SES and EchoStar of Englewood, Colorado, ordered the satellite from Airbus Defence and Space in August 2014 as a replacement for AMC-15, which is now 13 years old. EchoStar will lease the Ku-band payload on SES-11, rebranding it as EchoStar-105.

Both satellite operators originally anticipated the spacecraft launching in late 2016, but SpaceX's September 2016 Falcon 9 explosion set the mission back about a year.

EchoStar-105/SES-11 will cover the Americas, including Alaska, Hawaii, Mexico and the Caribbean, from the 105 degrees west orbital location. Once in orbit, EchoStar will lease the full Ku-band payload for a minimum of 10 years, with the option afterwards to renew on an annual basis. SES will operate the C- and Ka-band payloads, with the C-band payload replacing capacity from AMC-18.

SpaceX is conducting the mission from the Kennedy Space Center's Launch Complex 39A on the Florida coast.

In March, SES's Chief Technology Officer Martin Halliwell said the operator might use up to three pre-flown Falcon 9 boosters this year in an effort to normalize reusable rockets. Meeting that number would require a pre-flown booster for GovSat-1, a joint venture satellite with the government of Luxembourg, which is SES's last satellite scheduled to launch this year.

EchoStar 105/SES-11, a high-powered hybrid Ku and C-band communications satellite, is a dual-mission satellite for US-based operator EchoStar and Luxembourg-based operator SES. 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. 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.

EchoStar 105 was tailored to meet the Ku-band capacity needs of EchoStar's enterprise, media and broadcast, and U.S. government service provider customers, offering coverage of the 50 U.S. states and expanded reach to the Gulf of Mexico and the Caribbean.

SES-11, designed to accelerate the development of SES's U.S. prime video neighborhood and optimized for digital television delivery, joins SES-1 and SES-3 at the centre of SES's robust North American orbital arc, which reaches more than a hundred million TV homes. It also replaces C-band capacity for AMC-18, which SES offers over North America, including Hawaii, Mexico and the Caribbean, empowering businesses and governments to capture new opportunities and expand their reach.

EchoStar 105/SES-11 is the 47th satellite based on Airbus's highly reliable Eurostar E3000 platform. It will have a launch mass of 5,200 kg and spacecraft power of 12 kW.

September 25, 2017 by Chris Bergin



SpaceX is deep into pre-launch preparations for two upcoming missions that are set to lift off within a couple of days of each other. Both target launch dates have moved to the right by a matter of days, with the SES-11 mission from KSC's 39A now tracking an October 7 departure, while on the West Coast the Iridium NEXT-3 mission now has a launch placeholder of October 9.
Спойлер
Launch Date Realignment:

While both pre-launch flows are deemed to be issue-free, changes to the launch date targets are not unusual, especially for the busy Eastern Range.

Notably, it was the SES-11 mission that moved to the right by a few days.



The satellite, also called EchoStar 105, is a spacecraft with 24 Ku-band and 24 C-band transponders that will be used to support the continued development of the U.S. orbital arc media distribution neighborhood and provide coverage over North America, including Hawaii, Mexico and the Caribbean.

It will ride atop SpaceX's B-1031.2 booster – conducting its second flight after successfully lofting the CRS-10 Dragon to the International Space Station (ISS) earlier this year – a launch that was the maiden SpaceX launch from 39A since its transformation from its Space Shuttle era.

The launch date was previously tracking a flow that would have involved a Static Fire test on September 29 ahead of an October 2 launch.

That timeline has since moved to an October 2 placeholder for the Static Fire test, ahead of an October 7 launch date. No specific reason has been given for the change to the schedule.

An Atlas V, however, is also vying for the Eastern Range's attention in the first part of October, with another high-priority NRO mission. The NROL-52 mission is currently evaluating an October 5 launch date, although ULA has yet to confirm a set target due to the classified nature of the payload.

...

SpaceX does have separate launch teams for both its East and West coast operations, but can opt to protect its manifest running order with such realignments, as appears to have been the case with these two upcoming missions.

SpaceX engineers are readying two Falcon 9 rockets for launches Oct. 7 and Oct. 9 from Florida and California, setting up another quick turnaround to first deploy a large TV broadcasting satellite for SES and EchoStar over the United States with a previously-flown booster, then add 10 more spacecraft to Iridium's fleet of new-generation voice and data relay network.

First up is the Oct. 7 launch of an Airbus-built communications satellite from pad 39A at NASA's Kennedy Space Center in Florida for SES and EchoStar. The approximately 11,500-pound (5,200-kilogram) spacecraft will blast off aboard a reused Falcon 9 first stage during a two-hour launch window opening at 6:53 p.m. EDT (2253 GMT).

The launch was previously set for Oct. 2 but was pushed back to allow more time to complete preparations on the satellite in the aftermath of Hurricane Irma.

The portion of the satellite owned by SES, known as SES 11, will support digital video and television services over North America, replacing C-band communications capacity currently provided the AMC 18 satellite launched in 2006. SES says the new satellite's 24 C-band transponders will relay radio, television and video signals across the United States, including Hawaii and Alaska, Canada, Mexico and the the Caribbean.

EchoStar's part of the satellite, which it calls EchoStar 105, includes 24 Ku-band transponders tailored for television and other telecom services for commercial clients and the U.S. government, picking up the mission of the aging AMC-15 satellite launched in 2004.

The Oct. 7 launch will mark the 42nd flight of a Falcon 9 rocket, and the third time one of SpaceX's launchers has lifted off with a reused first stage booster. Designated as Core No. 31, the first stage set to loft the SES 11/EchoStar 105 satellite first flew in February, sending a Dragon supply ship toward the International Space Station before returning to land at Cape Canaveral.

The Falcon 9 rocket will deliver the SES 11/EchoStar 105 satellite toward an orbital perch more than 22,000 miles (36,000 kilometers) above the equator. The high-altitude target for the mission will require the first stage to descend to a landing on a floating platform in the Atlantic Ocean, officials said, leaving insufficient leftover fuel for maneuvers to return to Cape Canaveral.
