Heavy Communications Satellite Duo Rides to Orbit on Europe's Ariane 5 after three-week Delay
September 29, 2017

Riding on pillars of fire and smoke, Europe's Ariane 5 rocket blasted into the sunset over French Guiana on Friday, heading off on its final Geotransfer mission of the year with a pair of particularly heavy satellites for operators Intelsat and B-SAT to support a global network of cutting-edge communications satellites and beam down 8K Ultra-High Definition Television.

Ariane's fifth mission of the year started at 21:56 UTC when the 55-meter tall rocket jumped off its ELA-3 launch pad at the Guiana Space Center, rising into the twilit skies over the edge of the Amazon jungle before turning eastward under the power of its trusted Vulcain main engine and twin Solid Rocket Boosters that did most of the work for the first 135 seconds of the flight. After the boosters dropped away, Ariane 5 split open its payload fairing and continued on the first stage until just shy of T+9 minutes when the second stage took over for a 16 and a half-minute burn of its engine to accelerate the stack into a highly elliptical Geostationary Transfer Orbit.

Ariane 5 performed admirably while its engines were powering the vehicle into orbit and continued with a 22-minute ballistics phase to deliver the satellites into slightly different orbits with the 7.9-meter tall Intelsat 37e departing the stack 30 minutes after launch followed by the release of the smaller BSat-4a 17 minutes later to enable both to head off on their respective missions.

Friday's Ariane 5 launch marked the rocket's 95th mission and the 81st consecutive success for the workhorse launcher with one more flight to go in 2017 after Arianespace adjusted its manifest fr om an initial expectation of seven heavy-lift mission this calendar year. The last Ariane 5 mission of the year will utilize the ES variant of the rocket for a boost into Medium Earth Orbit with the next four satellites joining Europe's Galileo Navigation Satellite System.

Friday's launch marked another bread-and-butter mission for the Ariane 5, employing its ECA high-performance version to lift a pair of satellites into Geostationary Transfer Orbit – representing the vast majority of the launcher's business nowadays. In fact, Friday's mission was the vehicle's second heaviest GTO delivery with a total payload upmass of 10,838 Kilograms amassed by the two satellites and their adapters.

Riding in the front seat was Intelsat 37e, a massive communications satellite built by Boeing based on the 702MP platform for operation by Luxembourg's Intelsat as part of the company's satellite fleet. The 6,438-Kilogram satellite is the fifth in the company's Epic-NG series that delivers flexible coverage across the globe, leveraging the latest advances in satellite technology such as multi-band payloads, frequency re-use, power sharing capabilities and a combination of beam widths to deliver data-intensive services via fixed and steerable spot beams and broadcasting services through wide coverage beams.

The Intelsat 37e satellite hosts 90 C-Band, 275 Ku-Band and 37 Ka-Band transponders (36 MHz-equivalent units) covering the entirety of Europe, Africa and South America plus the Eastern U.S. and Canada. As the first satellite to use advanced Epic technology in all its bands, Intelsat 37e will deliver wireless backhaul, VSAT, enterprise and mobility services. Steerable beams in Ku/Ka-Band enable capacity to be directed where it is needed and enhanced power sharing capabilities for flexible assignment of power between shaped, fixed and steerable spot beams allows for an optimization for in-demand applications by region.

Intelsat 37e will operate for at least 15 years fr om an orbital location at 18°West wh ere it will replace the 16-year old Intelsat 901 satellite that is being decommissioned after surpassing its planned service life.

Heading into in the lower payload berth for the smaller of Ariane's two passengers was the 3,520-Kilogram BSat-4a, operated by Japan's Broadcasting Satellite System Corporation (B-SAT) and built by Space Systems Loral based on the popular SSL-1300 platform. The satellite carries an all-Ku-Band payload with 24 transponders for Direct-To-Home Television distribution in standard and high-definition formats as well as the 4K and 8K Ultra-HD resolutions.

Spiraling up into Geostationary Orbit, the BSat-4a satellite will park at 110° East wh ere it will initially provide expansion coverage with focus on 4K/8K before eventually taking over for the BSat-3a satellite that entered service in 2007. The satellite is being launched in 2017 to provide a maximum of margin before the 2020 Olympics in Tokyo which are planned to be broadcast in 4K and 8K though BSat-4a.

BSat-4a was ordered under a delivery-in-orbit contract in which SS/L procures the launch service for the satellite and is responsible for maneuvering the satellite into its operational orbit and completing all necessary testing & commissioning activity before turning the craft over to B-SAT for operational services.

The fifth Ariane 5 launch of the year enjoyed smooth early launch campaign until hitting a bump in the road when it had already passed the point of main engine ignition on September 5. Due to a problem sensed by the vehicle's onboard computer within an electronics component on one of the boosters, Ariane 5 triggered a shutdown of its engine – marking only the third post-ignition abort in the rocket's two-decade career. Ariane 5 returned to the Final Assembly Building to undergo replacement and re-testing of the suspect component as well as refurbishment on the Vulcain 2 engine after being fired.

Coming back from a 24-day delay, Ariane 5 rolled out to the ELA-3 launch pad Thursday afternoon after all re-checks showed the launcher systems to be ready. In position for liftoff, Ariane 5 entered a lengthy countdown of 11 hours and 23 minutes early on Friday, starting with power up of the launcher before an extensive testing campaign to award the vehicle a clean bill of health before tanking. All workers departed the launch complex by T-5 hours to allow 185 metric tons of -183°C Liquid Oxygen and -253°C Liquid Hydrogen to be pumped into the EPC first stage and ESC-A cryogenic second stage.

Loaded up on cryogenics, Ariane 5 stood fully fueled while final preparatory steps were run to transition the two satellites to battery power before the countdown switched into automatic mode at the T-7-minute mark after a brief delay due to an open item on the ground system. Under supervision by computers, Ariane 5 closed out propellant loading and started pressurizing its tanks, switched to internal power and configured its flight computers for launch with handoff to the vehicle occurring just seconds before ignition, coinciding with the retraction of the upper stage feed arms.

The Vulcain 2 engine started breathing fire once again when clocks hit zero, ramping up to a launch thrust of 96 metric-ton-force under close watch by computers that ensured the engine was up and running before commanding the twin boosters to light up, marking the point of no return.

Ariane 5 jumped off its launch pad at 21:56:07 UTC, just over twenty minutes after sunset at the equatorial launch base – lighting up the night over the French Guiana coast line as the launcher headed off with a total thrust of 1,420 metric-ton-force. A brief vertical climb was followed by the usual pitch and roll maneuvers that aligned Ariane 5 with an ascent path taking it straight east for a quick overflight of the Atlantic Ocean.

Burning some 3,600 Kilograms of propellant per second, Ariane 5 pushed through the sound barrier at T+49 seconds and encountered Maximum Dynamic Pressure at T+73 seconds when passing through 13 Kilometers in altitude.

The boosters did most of the work during the initial phase of the flight, each consuming 237 metric tons of solid propellant over the course of a two-minute and 15 seconds burn, helping Ariane 5 to accelerate to a speed of two Kilometers per second.

The 31.6-meter long EAP boosters separated at T+2 minutes and 22 seconds, 65 Kilometers in altitude when Ariane's onboard computers sensed the declining chamber pressures after the boosters ran out of propellant.

With the boosters gone, the ascending launch vehicle relied on the core stage's Vulcain 2 engine alone, delivering a thrust of 136,600 Kilogram-force when flying in the tenuous upper atmosphere.

Having departed the dense atmosphere, Ariane 5 split open and separated its 17-meter fairing halves three minutes and 23 seconds into the flight, shedding no-longer-needed weight as aerodynamic forces were no longer a danger to the satellites at altitudes of 112 Kilometers and above.

The first stage consumed its supply of 170 metric tons of LOX and LH2 after eight minutes and 56 seconds, having boosted the vehicle to a speed of 6.96 Kilometers per second. Four seconds after shutdown on the EPC, the 30.5-meter long stage separated 140 Kilometers over the Atlantic Ocean, clearing the second stage for ignition.

The 6,400-Kilogram-force HM-7B engine on the ESC-A second stage came to life nine minutes and four seconds into the mission, starting out on a lengthy propulsive flight phase of 16 minutes and 25 seconds to boost the stack into a highly elliptical orbit.

Tasked with accelerating the stack by another 2.4 Kilometers per second, the upper stage continued trekking east, being handed to downrange ground stations in Brazil, on Ascension Island and finally in Africa at Gabon and Malindi to cover the entirety of the mission.

The VA239 mission aimed for an orbit of 250 by 35,706 Kilometers at an inclination of 6 degrees, taking advantage of French Guiana's low latitude to inject the satellites into a low-inclination orbit to decrease their fuel expenditure when climbing to their operational orbits.

Having reached Africa's west coast, the upper stage shut down its main engine – trading the raw power of its rocket motor with the precision of its cold-gas thrusters that were up for over twenty minutes of maneuvering to dispatch the two passengers onto safe orbital paths.

Springs pushed the heavy Intelsat 37e away from the Sylda adapter 29 minutes and 50 seconds into the mission, embarking on its initial orbit raising campaign to take up station over the Atlantic Ocean to start out a multi-week commissioning campaign, getting ready to service four continents and the Atlantic region. With the first satellite on its way, ESC-A completed a re-orientation before dropping the Sylda adapter that held the upper passenger and enshrouded BSat-4a in the lower payload berth.

It was another 15 minutes of maneuvering after Sylda operation before BSat-4a was deployed to ensure no objects released by this launch would re-contact. BSat-4a separation 47 minutes after launch was met with applause at launch control as Ariane 5 advances its success streak, having been without failure since 2003.

For Ariane 5, the mission ended with the usual twenty-minute passivation sequence that included spinning the second stage up, venting down all tanks and powering off onboard systems.

Arianespace will be in action again on November 7/8 when Vega will make a nighttime liftoff to deliver the MN35-13 (Morocco EO Sat 1) Earth-imaging satellite for Morocco. The three-week delay to VA239 will have no effect on the VA240, currently looking at liftoff on December 12.

Ariane 5 rocket deploys satellites for Intelsat and B-SAT
September 29, 2017 Stephen Clark

Recovering from a last-second launch abort earlier this month, an Ariane 5 rocket climbed into space Friday night from Europe's spaceport in French Guiana to place two U.S.-built communications satellites in orbit for Intelsat and Broadcasting Satellite System Corp. of Japan.

After a nine-minute delay, the Ariane 5 rocket took off with 2.9 million pounds of thrust at 2156 GMT (5:56 p.m. EDT; 6:56 p.m. French Guiana time) Friday, heading toward the east over the Atlantic Ocean with the Intelsat 37e and BSAT 4a communications satellites.

Two side-mounted solid rocket boosters burned out and jettisoned around two-and-a-half minutes into the flight, and the Ariane 5's Swiss-made payload shroud fell away about a minute later.

The Ariane 5's Vulcain 2 main engine consumed around 700 pounds, or 320 kilograms, of super-cold liquid hydrogen and liquid oxygen propellants per second until shutting down at the nine-minute point of the flight.

A smaller HM7B engine ignited on the Ariane 5's second stage to send the Intelsat 37e and BSAT 4a spacecraft into an elliptical geostationary transfer orbit, aiming to guide the satellites into an orbit with a high point of 22,186 miles, a targeted low point of 155 miles and an inclination of 6 degrees.

A member of the Ariane launch team confirmed the rocket reached a near-perfect orbit, and Intelsat 37e and BSAT 4a separated from the launcher at approximately Plus+29 minutes and Plus+47 minutes, respectively.

Arianespace declared the flight a success, extending the Ariane 5's streak of consecutive successful launches to 81 in a row, a record dating back to 2003. Friday night's mission marked the fifth Ariane 5 launch of the year, and the 95th Ariane 5 flight overall.

"Arianespace is proud to share this fifth successful Ariane 5 launch of the year, its 81st in a row, with our American and Japanese customers," said Stephane Israel, CEO of Arianespace.

The mission's first launch attempt Sept. 5 was aborted after ignition of the Vulcain main engine, and before the irreversible ignition of the boosters, when a computer discovered a problem with an electrical component on one of the side-mounted motors.

Ground teams rolled the Ariane 5 back to its vertical assembly building at the spaceport to replace the suspect part and reattach fueling arms to the rocket's second stage, which retracted as designed in the final seconds of the halted countdown.

Two U.S.-built satellites are bolted on top of the Ariane 5 rocket.

The 14,193-pound Intelsat 37e satellite, occupying the upper position in the Ariane 5's dual-payload stack, will beam broadband, wireless communications, television and government services across the Americas, the Atlantic Ocean, Europe and the Middle East from a perch in geostationary orbit at 18 degrees west longitude. Made by Boeing in El Segundo, California, Intelsat 37e was the fifth new-generation Epic-series satellite launched for Intelsat.

"Intelsat 37e includes new innovations that further our performance goals," said Stephen Spengler, Intelsat's CEO. "The Intelsat 37e satellite features power-sharing technology to optimize performance for specific applications and regions. This satellite also includes steerable beams to support high-performance mobility and government applications in Africa, Europe and the Americas."

Designed for a lifetime of at least 15 years, Intelsat 37e is the most capable Intelsat satellite ever launched. The new satellite will replace Intelsat 901 launched aboard an Ariane 4 rocket in June 2001.

"Intelsat 37e is also the first high-throughput satellite to offer full beam interconnectivity between C, Ku and Ka-band beams," Spengler said. "This unique feature, enabled by the digital payload, underscores the flexibility and high performance our customers have come to expect from the Intelsat Epic fleet."

Companies such as Speedcast, Omni-Access, Algeria Telecom and TIM Brazil will be among the first customers to deploy services on Intelsat 37e, Intelsat said in a statement, supporting 3G and 4G wireless networks and broadband services on commercial ships.

A Sylda adapter was discarded from the Ariane 5 a few minutes after separation of Intelsat 37e, revealing the 7,760-pound BSAT 4a spacecraft, the mission's other satellite passenger.

BSAT 4a will provide HD, 4K and 8K Ultra HD television broadcasts over Japan for Broadcasting Satellite System Corp. The satellite was built by Space Systems/Loral in Palo Alto, California, and carries 24 Ku-band transponders.

"BSAT 4a is the world's first 8K satellite," said Lincoln Day, senior executive director for the BSAT 4a program at SSL. "It will provide advanced television services for Japan, and it will provide 4K and 8K satellite television for the 2020 Olympics that happen in Tokyo, as well as the Paralympics that happen in that summer."

SSL will hand over control of the BSAT 4a satellite to its Japanese owners in October. BSAT 4a will replace the BSAT 3a satellite launched by an Ariane 5 rocket in 2007.

Both payloads launched Friday will fire on-board thrusters to reach their final circular orbits more than 22,000 miles over the equator. The orbit-raising burns will take around two weeks, then the satellites will complete their final solar array and antenna deployments and functional testing before starting commercial service.

Intelsat 37e will operate from a perch in geostationary orbit at 18 degrees west longitude, while BSAT 4a is heading for a geostationary slot at 110 degrees east longitude.

Arianespace's next launch is scheduled for Nov. 7, when a lightweight Vega rocket will send up a European-built reconnaissance satellite for the Moroccan government.

The next Ariane 5 launch is on track for Dec. 12 with four European Galileo navigation satellites.
