GOES-R’s Grand Ascension
On schedule, a United Launch Alliance’s Atlas V embraced GOES-R and lifted the satellite high, along with the spirits of those who anticipate that the much improved and highly heralded technology will vastly improve weather
GOES-R is NOAA’s most advanced geostationary weather satellite to-date. But how different can this satellite truly be?
Imagine going from a black and white TV to HD overnight. GOES-R is faster and clearer than current GOES satellites and will provide forecasters with more detail and information than previously obtainable.
Using a powerful new instrument called the Advanced Baseline Imager, or ABI, GOES-R will provide data and imagery about weather over the entire Western Hemisphere in real-time—the satellite can even accomplish this work as frequently as every 30 seconds! This enables NOAA to gather data using three times more channels, four times the resolution,
at five times faster than before.
This faster, more accurate data means better observations of developing storms. The ABI will be used for a wide range of applications related to weather, oceans, land, climate and hazards.
The GOES-R Series includes four satellites and is the nexgen of GOES satellites that will provide continuous imagery and atmospheric measurements of the Earth’s Western Hemisphere.
GOES-R will produce images of weather patterns and severe storms as frequently as every 30 seconds, which will contribute to more accurate and reliable weather forecasts and severe weather outlooks, including thunderstorm, hurricane and tornado tracking and intensity forecasting.
GOES-R will also provide improved detection and observations of meteorological phenomena that directly impact public safety, protection of property and economic health and development.
Designed and built by Lockheed Martin, the GOES-R satellite includes six instruments that fit into three classifications: Earth-pointing, solar-pointing and in-situ (near environment). Lockheed Martin is providing three instruments:
• The Solar Ultraviolet Imager (SUVI)
• The Geostationary Lightning Mapper (GLM)
• The magnetometer
Three additional instruments include:
• The Advanced Baseline Imager (ABI) developed by the Harris Corporation
• The Extreme Ultraviolet X-Ray Irradiance Sensors (EXIS) from the University of Colorado’s Laboratory for Atmospheric and Space Physics
• The Space Environmental In-Situ Suite (SEISS) from the Assurance Technology Corporation
The GOES-R Series is a collaborative effort between the National Oceanic and Atmospheric Administration (NOAA) and the National Aeronautics and Space Administration (NASA) to develop, launch and operate the satellites.
GOES satellites have played a vital role in weather forecasting, severe storm tracking and meteorological research since the first GOES was launched on a Delta rocket in 1975. ULA’s Atlas and Delta rockets have launched every satellite in the GOES series.
ATLAS V 541
One of the most powerful rockets in the Atlas V fleet, the 541 configuration, with four solid rocket boosters, provides the optimum performance to precisely deliver a range of mission types.
In addition to completing two national security missions, an Atlas V 541 configuration rocket launched NASA’s Curiosity rover on its 10 month, 354 million mile journey to the surface of Mars.
• First Launch: November 26, 2011 Launches to date: 3
• Performance to GTO: 8,290 kg (18,270 lb)
• Performance to LEO-Reference: 17,410 kg (38,400 lb)
Aerojet Rocketdyne, a subsidiary of Aerojet Rocketdyne Holdings, Inc., successfully supported the launch of this GOES-R satellite for the National Oceanic and Atmospheric Administration (NOAA) and NASA.
Aerojet Rocketdyne propulsion systems on the Atlas V included the RL10C-1 upper-stage engine, four Solid Rocket Boosters (SRBs), six helium pressurization tanks and a dozen Centaur upper-stage Reaction Control System thrusters (RCS).
On the GOES-R satellite, Aerojet Rocketdyne provided all of the monopropellant hydrazine rocket engines as well as the electric propulsion subsystem.
“Weather is constantly changing, and the faster scientists can predict those changes, the better communities can prepare for severe conditions and phenomena, such as forest fires and volcanic ash. Aerojet Rocketdyne is honored to help launch this critical satellite that will help keep people and their neighborhoods safe,” said Aerojet Rocketdyne CEO and President, Eileen Drake.
Aerojet Rocketdyne’s role in the launch began during liftoff when four SRBs ignited to provide 1.5 million pounds of total increased thrust to launch the Atlas V rocket. (Each 67-foot-long, 5-foot-wide composite motor case contains more than 90,000 pounds of propellant, providing more than 375,000 pounds of liftoff thrust.) All Atlas V launches requiring extra boost have flown Aerojet Rocketdyne SRBs.
After separation of the first stage, a single RL10C-1 upper-stage engine ignited to place the payload into orbit, with the RCS thrusters maintaining vehicle orientation and the pressurization tanks maintaining pressure levels in the liquid oxygen/liquid hydrogen tanks.
The RL10C-1 delivers 22,890 pounds of thrust to power the Atlas V upper stage, using cryogenic liquid hydrogen and liquid oxygen propellants during its operation.
The RL10C-1 was developed from the RL10 family of upper-stage engines, which have accumulated one of the most impressive track records of accomplishments in the history of space propulsion.
More than 470 RL10 engines have supported launches over the last 50 years, helping to place military, government and commercial satellites into orbit, and powering scientific space-probe missions on every planetary mission in our solar system.
Aerojet Rocketdyne developed a new MR-401 Low Thrust Rocket (LTR) for the GOES-R program that enables compliance with the unique GOES-R mission requirements.
The GOES-R satellite has 16 of these MR-401 rockets onboard providing vehicle attitude control, momentum wheel desaturation and east/west stationkeeping.
In addition to the 16 LTRs, Aerojet Rocketdyne also provided the 4.4kW MR-510 electric propulsion subsystem which provides all north/south stationkeeping for the GOES-R mission, as well as end of life decommissioning.
The MR-510 Electric Propulsion (EP) subsystem consists of four MR-510 Arcjet thrusters, one 4.4kW Power Conditioning Unit (PCU), and the electrical harnessing to connect the PCU to the thrusters.
The MR-510 EP system enables increased payload capability for the GOES-R mission due to the significant savings in propellant mass provided by the 3x improvement in fuel efficiency.
ARDÉ, a subsidiary of Aerojet Rocketdyne based in New Jersey, provided the pressure vessels on the first and second stages of the launch vehicle.
Providing critical hardware for the United Launch Alliance (ULA) Atlas V vehicle and NASA’s Geostationary Operational Environmental Satellite-R Series (GOES-R) NASA weather satellite that was launched on Saturday, November 19th, from Cape Canaveral Air Force Station, Florida, was Orbital ATK.
Using advanced fiber placement manufacturing and automated inspection techniques, Orbital ATK produced three components for the ULA Atlas V vehicle, including the 10-foot diameter composite heat shield that provides essential protection to the first stage engine, the Centaur Interstage Adapter that houses the second stage engine, and the boattail that adapts from the core vehicle to the five-meter diameter fairing.
Orbital ATK fabricated these structures at its Iuka, Mississippi, facility. This is the 66th Atlas V launch using Orbital ATK-built composite structures.
This flight also marked the 32nd successful flight of the Orbital ATK retrorocket motors. Eight of these solid motors supported separation of the spent first stage.
The Atlas V retrorocket is built by Orbital ATK’s Defense Systems Group at its facility in Elkton, Maryland.
In addition, Orbital ATK manufactured the Reaction Control System propellant tank for the ULA Atlas V at their Commerce, California, facility.
The GOES-R series satellites will contribute to more accurate and reliable weather forecasts and severe weather outlooks via continuous visual and infrared imagery and atmospheric measurements of Earth’s Western Hemisphere, total lightning data, solar imaging and space weather monitoring.
NOAA manages the GOES-R program with an integrated NOAA-NASA program office organization co-located at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
The company’s Space Components Division facilities in Maryland, California and Utah provided numerous subsystems for the GOES-R satellite, including loop heat pipes for thermal control of the Advanced Baseline Imager (ABI) and Global Lightning Mapper (GLM) instruments, fuel, oxidizer, and pressurant tanks, the primary bus structure, also containing thermal control elements, and three optical bench stable structures supporting the ABI and Solar Pointing Platform (SPP).
Orbital ATK also provided a coilable lattice boom for the GOES-R Magnetometer, continuing the success of company-built booms on previously launched GOES-N, -O and -P satellites.
Galileo x4 Seize The Day—Constellation Completed
An Arianespace Ariane 5 launch vehicle has successfully placed four satellites into orbit, thereby completing the European Galileo satellite navigation constellation.
This was the 75th time an Ariane 5 has completed a mission from the European space port in Kourou, French Guiana.
This 233rd launch noted that the upper stage for this Ariane 5 mission was powered by the re-ignitable Aestus engine, which has already been used successfully for launches of the European ATV space vehicle.
The launch performance of this Ariane 5 ES is 3276 kg to a circular orbit at an altitude of 22,922 km (of which 2,858 kg were accounted for by the four satellites at 714 or 715 kg each). They were injected into orbit by a 418 kg dispenser that was specifically developed and built by Airbus Safran Launchers for these Galileo launches.
This launch was also the first opportunity to fly a Vulcain engine part produced by additive layer manufacturing (ALM) using direct metal laser sintering, which significantly shortened the production cycle and reduced the quantity of material lost through machining.
The Ariane 5 launcher once again demonstrated full flexibility, which enabled the rocket to carry heavy payloads into LEO, two satellites into geostationary transfer orbit, a single satellite with an optimized service lifetime, or several satellites to MEO, as was the case today.
Airbus Safran Launchers is lead contractor for the Ariane 5 launchers. The company coordinates an industrial network of more than 550 companies in 12 European countries (including more than 100 small and mid-sized Enterprises - SMEs).
Airbus Safran Launchers oversees the entire industrial chain, from management of launcher performance upgrades, to production management, to final adjustment and supply of the mission flight software.
This chain includes equipment and structures, engines manufacturing, integration of the various stages and finally launcher integration in French Guiana.
Airbus Safran Launchers is also industrial lead contractor for Europe’s future Ariane 6 launcher, which is scheduled for a first flight in 2020 and which will replace Ariane 5 in about 2023.
The Ariane 233 flight in figures:
• 8th launch of an Ariane 5
• 6th Ariane 5 ES launcher equipped with its reignitable Aestus engine
• 12th Ariane 5 launch with Airbus Safran Launchers as lead contractor
• 63rd consecutive success by a launcher fitted with a Vulcain® 2 engine
• 21st consecutive success by a launcher fitted with the Aestus engine
Alain Charmeau, the CEO of Airbus Safran Launchers, said, “This 6th launch of 2016 combines a new record with innovation. Not only has Ariane 5 broken the consecutive successful launch record of its predecessor Ariane 4, but it has once again demonstrated its flexibility by placing four satellites in a circular orbit simultaneously and at an altitude of 22,922 km.
“I wish to congratulate the industrial teams who once again demonstrated the extraordinary flexibility of Ariane 5. This year, in addition to the usual dual launches, the launcher has shown itself capable on two occasions of placing a single satellite in orbit for commercial customers, and now it has successfully carried out this quadruple launch for a European institutional customer. I wish to thank ESA, the European Commission, Arianespace and CNES for their confidence and for their constant support.”

He was also a key figure in establishing the ground rules for adding Carrier ID to digital video carriers, prior to taking the position of Executive Director of IRG in 2011.
A New VANTAGE For Telesat
A new satellite that will possess two high throughput payloads—one Ku and the second Ka-band—is going to be procured by Telesat
To be named Telstar 19 VANTAGE, this satellite will co-locate with Telesat’s Telstar 14R at 63 degrees West, a prime orbital slot for coverage of the Americas.
Telesat expects to enter into a construction agreement for Telstar 19 VANTAGE in the coming weeks.
Telstar 19 VANTAGE will be the second of a newgen of Telesat satellites that have been optimized to serve the types of bandwidth intensive applications that are increasingly being used across the satellite industry.
Hughes Network Systems LLC (Hughes) has made a significant commitment to use the satellite’s high throughput Ka-band capacity in South America to expand their broadband satellite services.
The satellite has additional high throughput Ka-band capacity over northern Canada, the Caribbean and the North Atlantic Ocean and will also provide high throughput and conventional Ku-band capacity over Brazil, the Andean region and the North Atlantic Ocean.
According to Dan Goldberg, Telesat’s President and CEO, Telstar 19 VANTAGE will be a versatile, state-of-the-art satellite optimized to serve growing markets in the Americas from Telesat’s prime 63 degrees West location. The company is pleased to have Hughes as an anchor tenant on this spacecraft and will be delivering new, high throughput capacity to serve Latin America, northern Canada and mobile broadband requirements in the Caribbean and North Atlantic.
Noordwijk Witnesses Successful Testing Of Sentinel-2B
The test program for Europe’s next Copernicus satellite, the Sentinel-2B, has been successfully finished at ESA’s technology Center ESTEC in Noordwijk, The Netherlands.
The second Sentinel-2 Airbus built satellite will now be readied for shipment to the Kourou spaceport in French Guiana in January of 2017.
The satellite is scheduled for an early March 2017 lift-off via Vega. Copernicus, Europe’s environmental monitoring program, is led by the European Commission (EC) in partnership with the European Space Agency (ESA).
The Copernicus Sentinels supply remote sensing data of the Earth, delivering key operational services related to environment and security.
Offering “color vision” for the Copernicus program, Sentinel-2B, like its twin satellite Sentinel-2A, will deliver optical images from the visible to short-wave infrared range of the electromagnetic spectrum.
From an altitude of 786 kilometers, the 1.1 ton satellite will deliver images in 13 spectral bands with a resolution of 10, 20 or 60 meters and a uniquely large swath width of 290 km.
The optical design of the Multi Spectral Instrument (MSI) has been optimized to achieve state-of-the-art imaging quality across its very wide field of view.
With its multispectral imager and wide swath coverage, the Sentinel-2 mission not only offers continuity, but with its more than 100 km increase in swath width, also expands on previous missions.
The telescope structure and the mirrors are made of silicon carbide, which provides very high optical stability and minimizes thermo-elastic deformation, resulting in an excellent geometric image quality. This is unprecedented in this category of optical imagers.
The data gathered are used for monitoring land use and changes, soil sealing, land management, agriculture, forestry, natural disasters (floods, forest fires, landslides, erosion) and to assist humanitarian aid missions. Environmental observation in coastal areas likewise forms part of these activities, as does glacier, ice and snow monitoring.
The Sentinel-2-mission is based on a constellation of two identical satellites, Sentinel-2A and Sentinel-2B, in the same orbit, 180 degrees apart for optimal coverage and data delivery.
The satellites are orbiting the Earth every 100 minutes covering all Earth’s land surfaces, large islands, inland and coastal waters every five days. Sentinel-2A, which is identical in design, was launched on June 23, 2015. Since then, the satellite has been performing as expected.
A total of 51,762 users have self-registered on the Sentinels Scientific Data Hub. About 168,000 products are available for download for a total volume of 433 TB. Overall, a total volume of 1.9 Petabytes has been downloaded by user communities.
The Sentinel-2 mission has been made possible thanks to the close collaboration between ESA, the European Commission, industry, service providers and data users.
The mission’s development has involved around 60 companies, led by Airbus Defence and Space in Germany for the satellites and Airbus Defence and Space in France for the multispectral instruments, while Airbus Defence and Space in Spain is responsible for the mechanical satellite structure.
Better Satellite World Award Honorees Brought To Light By SSPI
Founded in 1983, the Society of Satellite Professionals International is on a mission to make the satellite industry one of the world’s best at attracting and engaging the talent that powers innovation—with more than 4,000 members in +40 nations, this is the largest satellite industry association in the world.
The Society of Satellite Professionals International (SSPI) has now revealed the four recipients of their second annual Better Satellite World Awards, which honor established companies and disruptive innovators for making our world a more prosperous, healthier, better-educated, more sustainable and inclusive home for all humankind.
Selected by an international jury for their achievements were: DigitalGlobe, Disaster Tech Lab supported by Globalstar, Global VSAT Forum and Outernet.
The recipients were honored at the second Better Satellite World Awards Dinner on December 5th at London’s prestigious One Whitehall Place.
“Satellite is the world’s invisible but indispensable technology,” said executive director Robert Bell, “and our awards honor both for-profit companies and nonprofit organizations for using satellite in ways that make our world a better place. Our awards dinner in London gives us the chance to salute organizations that are quietly having a global impact.”
According to SSPI, recipients for the Better Satellite World Awards were evaluated in four categories. These were global or regional impact; distribution of knowledge for the improvement of living standards; governance and commerce; and communication and humanity.
The selection of the recipients for the Better Satellite World Awards was made by an international jury consisting of members of the SSPI Satellite Hall of Fame and distinguished industry professionals.
The Better Satellite World Awards Dinner in London was produced by SSPI and the organization’s UK and Isle of Man Chapters, with the support of international law firm Milbank as well as Globecomm, Arianespace, ManSat and Newtec.
The Better Satellite World Award Recipients
DigitalGlobe is the world’s leading provider of high-resolution Earth imagery, data, and analysis.
The company is a trusted partner of dozens of industries and communities worldwide – from environmental monitoring and mapmaking, to defense and intelligence, to urban planning and public safety.
DigitalGlobe has also become a leader in providing humanitarian aid by supplying local, national, and international authorities and media with imagery and information products that support response and recovery activities in the aftermath of earthquakes, floods, hurricanes, and other natural disasters.
In a recent humanitarian victory, DigitalGlobe enabled the Associated Press to expose a slave fishing operation in Papua New Guinea. The company supplied the AP with high-accuracy, high-resolution imagery that only DigitalGlobe satellites can collect, which showed the slave fishing operation in the act and spurred a myriad of positive outcomes. The Seafood from Slaves investigation led to a series of arrests, the dismantling of a slaving operation, the freeing of more than 2,000 slaves, and a change to US law that had previously allowed slave-produced goods to be sold in the United States. For its reporting on the issue, the AP won the 2016 Pulitzer Prize for Public Service. digitalglobe.com

Syed Karim, the founder of Outernet, describes it as “a universal information service available to all of humanity.”
Founded in 2014 as a private company headquartered in Chicago, Outernet now provides a global data delivery service over three Inmarsat I4 global beams.
The company provides a content delivery service which focuses on making the most useful knowledge from the Internet available to those in areas with no connectivity. Syed Karim conveyed this vision to the world as a speaker at the TedGlobal 2014 event.
In many places around the globe, Internet connectivity is prohibitively expensive, sometimes costing as much as ten times the average monthly income. Outernet creates offline versions of knowledge found on the web and broadcasts that information to people who have no access to the Internet.
The company currently operates a low bitrate global broadcast, which will expand over time to include the delivery of digital curricula and educational videos. outernet.is/
