Discussion thread for SES-14 satellite

Q1-2018 on Ariane 5



Press Release: Airbus Defence and Space to build SES-14 satellite  [Feb. 16, 2015]
Quote
Airbus Defence and Space, the world’s second largest space company, has been awarded a contract by SES, one of the world’s leading satellite operators, to design and develop SES- 14, a highly innovative telecommunications satellite.

SES-14 is the first high-power satellite in the 4-tonne class. It will be based on Airbus Defence and Space’s ultra-reliable Eurostar platform in its E3000e variant, which exclusively uses electric propulsion for orbit raising (EOR), taking advantage of the reduction in mass that this technology enables with an exceptionally large payload.

The satellite combining power and flexibility will have a double mission. The first will be a wide-beam payload of C and Ku-band, covering the Americas plus a link to Europe. The other payload, called High Throughput Satellite (HTS) with numerous user beams, will combine an on-board processor with multi-beam coverage of the Americas and the North Atlantic.

“SES once again demonstrates its responsiveness in a changing market, and we are pleased to be able to provide them with our very best technological innovation for both the payload and the platform,” said François Auque, Head of Space Systems. “On SES-14, as on SES- 12, the mass saving from electric propulsion enables us to combine two high-capacity missions, equivalent to two conventional satellites in one satellite”.

Martin Halliwell, Chief Technical Officer, SES, commented: “The procurement of SES-14, is a boost to our offer to customers in the Americas and further solidifies SES’s positioning in dynamic and demanding markets. The new spacecraft combines a large footprint with a powerful hybrid capacity offer and significant spacecraft technology innovations. It will help us to capture important growth potential, address the needs of video and enterprise customers and support the development of Next Generation Video and Next Generation Data services. Furthermore, it complements O3b’s high throughput satellite capacity in the medium earth orbit and helps us to deliver a truly unique and integrated offering”.

SES-14 will carry seven antennas. It will have a take-off weight of 4,200 kg and an electric power of 16 kW. The satellite is scheduled for launch in late 2017 and its electric propulsion system will enable it to reach geostationary orbit in four months, depending on the type of launcher used. Its nominal operational position will be 47.5/48 degrees West. It has been designed to remain in service in orbit for more than 15 years.

SES-14 is the 12th Eurostar satellite and the second all-electric satellite ordered by SES to Airbus Defence and Space. Nine of these satellites are in operational service and two are under construction.

Satellite fleet operator SES on Feb. 25 said two of the three satellites it ordered the previous week will be launched aboard SpaceX Falcon 9 rockets in 2017... SES-14 and SES-16/GovSat satellites would be launched on separate Falcon 9 vehicles.

SES-14, under construction by Airbus Defence and Space of Europe, is expected to weigh 4,200 kilograms at launch.
...
SpaceX rival Arianespace of Europe did not bid on either launch because both satellites are too heavy to fit into the lower position of the Ariane 5 rocket given the heavier upper-berth passengers that Evry, France-based Arianespace has booked for 2017.

An SES official confirmed that Arianespace did not bid for either of the two contracts. Satellites in the 4,000-kilogram class have limited launch options in today’s market. The Russian-built Proton rocket, marketed commercially by International Launch Services, typically launches satellites weighing 5,000 kilograms or more.

SES switches SpaceX and Arianespace launches to mitigate cost of satellite failure
by Peter B. de Selding | Aug 28, 2017

PARIS — Satellite fleet operator SES, which this year has suffered both predictable satellite-launch delays and unpredictable satellite failures, on Aug. 28 said it would move a satellite from launch-service provider SpaceX to Arianespace to minimize revenue losses.
As a result, the SES-14 satellite will launch aboard an Ariane 5 ECA rocket early in Q1 of next year rather than a less-clear Q1 launch date offered by SpaceX. SpaceX instead will launch the heavier SES-12 satellite, up to now slated for an Ariane 5, on a Falcon 9 vehicle in Q1 2018.

NASA GOLD (Global-scale Observations of the Limb and Disk)  payload is flying on SES-14.

CU LASP: Quick Facts: Global-scale Observations of the Limb and Disk (GOLD)

CU-Boulder to receive $36 million from NASA for space weather mission [Apr. 12, 2013]
Quote
The University of Colorado Boulder will receive roughly $36 million from NASA to build and operate a space instrument for a mission led by the University of Central Florida that will study Earth’s upper atmosphere to learn more about the disruptive effects of space weather.

The mission, known as the Global-scale Observations of the Limb and Disk, or GOLD, involves imaging Earth’s upper atmosphere from a geostationary orbit some 22,000 miles above the planet. The mission is expected to have a direct impact on the understanding of space weather like geomagnetic storms that alter the temperature and composition of Earth’s atmosphere, which can disrupt communication and navigation satellites, affecting everything from automobile GPS and cell phone coverage to television programming.

The GOLD mission, which is being led by research scientist Richard Eastes of the University of Central Florida, will launch aboard a commercial communications satellite as a “hosted” payload.  Such payloads, which are secondary to the satellite’s main objective, represent the most cost-effective way to reach geostationary orbit, said CU-Boulder aerospace engineer Mark Lankton of the Laboratory for Atmospheric and Space Physics, the GOLD project manager.

“LASP is extremely pleased to be working on this mission with Richard Eastes at the University of Central Florida, who we have been collaborating with for seven years,” said Lankton. “This mission is one of the first to involve a science instrument being launched on a communication satellite, which is a terrific idea and exactly the right way to run a quality mission on a smaller budget.”

The LASP instrument, known as an imaging spectrograph, weighs roughly 60 pounds and is about 2 feet long and about 1 foot tall and 1 foot wide – roughly the size of a microwave oven.  It will launch aboard a commercial satellite built by SES Government Solutions in McLean, Va. The LASP instrument will be gathering data on Earth’s upper atmosphere in the far ultraviolet portion of the electromagnetic spectrum.

“GOLD’s imaging represents a new paradigm for observing the boundary between Earth and space,” said Bill McClintock, the deputy principal investigator on the CU-Boulder spectrograph and a senior research scientist at LASP. “It will revolutionize our understanding of how the sun and the space environment affect our upper atmosphere.”

A geosynchronous orbit is an orbit that completes one revolution in the same amount of time it takes for the Earth to rotate once on its polar axis. “We will be able to view almost a complete hemisphere of the Earth, almost all the time, with this orbit,” said Lankton.

The mission scientists will be looking for the effects of space weather on the upper atmosphere -- the ionosphere and thermosphere located roughly 50 miles to 350 miles above Earth – caused by the sun and Earth’s lower atmosphere, said Lankton.  “The giant driver is the sun, including geomagnetic storms that can cause bright auroras and the disruption of satellite communications,” he said.

Lankton said the science team also will investigate the effects that atmospheric waves and tides from Earth’s lower atmosphere have on the thermosphere-ionosphere system. The mission will make use of other instruments gathering data on the sun, including LASP’s $42 million Extreme Ultraviolet Variability Experiment flying on NASA’s Solar Dynamics Observatory.

Roughly 40 LASP researchers will be working on the GOLD mission when it is at full strength, including five to 10 students, split about evenly between undergraduates and graduates, said Lankton.  Other participants in the GOLD mission include the National Center for Atmospheric Research in Boulder, the University of California, Berkeley, Computational Physics Inc. of Springfield, Va., and the National Oceanic and Atmospheric Administration.

The GOLD mission is part of NASA’s new Heliospheric Explorer Program designed to provide space observations to study Earth’s ionosphere and thermosphere.  The mission is slated for launch in 2017. NASA Explorer missions of opportunity, such as GOLD, are capped at $55 million each.
