Ariane 5 maintains Arianespace's track record of success by launching the ASTRA 1N and BSAT-3c/JCSAT-110R satellites[/size]


August 6, 2011 – Ariane Flight V203

Arianespace orbited a pair of commercial relay satellites for direct television broadcasting services tonight on Ariane 5's fourth heavy-lift mission of 2011.

During a 38-minute flight from the Spaceport in French Guiana, this workhorse vehicle lofted the ASTRA 1N and BSAT-3c/JCSAT-110R spacecraft, delivering an estimated payload lift performance to geostationary transfer orbit of 9,095 kg. – which included a combined mass of 8,240 kg. for the two satellites, along with the launcher's dual-payload dispenser system and associated integration hardware.

It marked the 203rd flight of an Ariane since the family of European-developed commercial launchers began operation in 1979, and was the 59th launch of an Ariane 5.

The precision of Ariane 5 was demonstrated once again tonight, highlighting the on-target repeatability of this vehicle.  The estimated orbital parameters at its cryogenic upper stage's injection were:
- Perigee: 249.7 km. for a target of 249.7 km.
- Apogee: 35,957 km. for a target of 35,952 km.
- Inclination: 2.01 deg. for a target of 2.00 deg.

ASTRA 1N was deployed first during the mission, and marked the 11th satellite launched for SES ASTRA by Arianespace – and the 34th entrusted to the company by the SES group.

Fitted with 52 active Ku-band transponders, ASTRA 1N was built by EADS Astrium based on the Eurostar E3000 platform, and had an estimated liftoff mass of 5,350 kg.  It initially is to deliver interim capacity from an orbital position of 28.2 deg. East, and subsequently will move to SES ASTRA's prime location at 19.2 deg. East for primary and backup services during a designed operational lifetime of 15 years.


Tonight's mission marked the 59th liftoff of Ariane 5 from the Spaceport's ELA 3 launch complex in French Guiana, and was the workhorse vehicle's fourth flight in 2011.

The BSAT-3c/JCSAT-110R spacecraft – which was released second in tonight's flight sequence – was manufactured by Lockheed Martin Commercial Space Systems as part of a turnkey contract for Japanese operators B-SAT Corporation and SKY Perfect JSAT Corporation. Produced using an A2100 A platform and weighing approximately 2,910 kg. at launch, this was the 41st Lockheed Martin satellite provided to Arianespace for launch.

BSAT-3c/JCSAT-110R is equipped with 24 active Ku-band transponders, and will be positioned at 110 deg. East longitude, with its primary mission to provide direct TV broadcast links for all of Japan.

Today's successful flight reinforced Arianespace's commercial launch services leadership role, which will be further strengthened with the upcoming introduction of its medium-lift Soyuz and lightweight Vega – to operate side-by-side with Ariane 5 at the Spaceport.

"Since the beginning of this year, we have launched an Automated Transfer Vehicle to the International Space Station, six telecommunications satellites, and six constellation satellites," explained Arianespace Chairman & CEO Jean-Yves Le Gall.  "It shows that Arianespace leads the pack once again this year, as – since the beginning of 2011 – only two other satellites have been launched by our competitors; and one of those, to our knowledge, did not arrive intact in orbit."

Arianespace's previous Ariane 5 flights during 2011 orbited the ST-2 and GSAT-8 telecommunications satellites on May 20; the Yahsat Y1A and Intelsat New Dawn relay spacecraft on April 22; and the Johannes Kepler Automated Transfer Vehicle on February 16.  In addition, a July 13 Soyuz mission from Baikonur Cosmodrome – performed on behalf of Arianespace by its Starsem affiliate – delivered six spacecraft for Globalstar's second-generation satellite network.

"And the successes will continue, as we still have in our order book no less than 18 Ariane 5 launches, to which are added 17 launches of Soyuz and the future missions with Vega," Le Gall said.

Arianespace's next Ariane 5 mission is set for September 9, carrying another SES satellite – SES 2 – along with Arabsat 5C for the Arab Satellite Communications Organization (Arabsat).[/size]

A boost for direct broadcast satellites: ASTRA 1N and BSAT-3c/JCSAT-110R in orbit[/size]

Kourou, August 6, 2011

On Saturday, August 6, 2011, Arianespace successfully launched two satellites mainly intended for direct-to-home (DTH) television broadcasting: ASTRA 1N for the Luxembourg-based operator SES Astra, and BSAT-3c/JCSAT-110R for the American manufacturer Lockheed Martin Commercial Space Systems, as part of a turnkey contract for the Japanese operators B-SAT Corporation and SKY Perfect JSAT Corporation.

203rd Ariane launch, 59th Ariane 5 launch, 45th success in a row for Ariane 5

This latest successful Ariane 5 launch, the fourth in 2011, once again proves the launcher's operational capabilities. Ariane 5 handles a complete range of missions, from commercial launches into geostationary orbit to launches into special orbits.

This was the 59th launch of an Ariane 5, and the 45th successful launch in a row.

Ariane 5 is the only heavy launcher now on the commercial market capable of simultaneously launching two payloads.

This latest successful launch clearly shows that Arianespace's launch Service & Solutions continue to set the global standard and guarantee independent access to space for all customers, including national and international space agencies, private operators and governments.

Supporting prestigious operators worldwide

Arianespace offers the launch solutions that best match the requirements of leading operators worldwide.

Over the last two decades, Arianespace and SES have developed an exceptional relationship. ASTRA 1N is the 34th satellite from the SES group (Euronext Paris and Luxembourg Bourse: SESG) to use the European launcher. SES operates the leading direct-to-home (DTH) TV broadcast system in Europe, based on its Astra satellites, serving more than 135 million households via DTH and cable networks.

BSAT-3c/JCSAT-110R is the 26th satellite for which Japanese operators have chosen the European launcher, and the 41st Lockheed Martin-built platform to be launched by Arianespace.

ASTRA 1N/BSAT-3C/JCSAT-110R mission at a glance

The mission was carried out by an Ariane 5 ECA launcher from Europe's Spaceport in Kourou, French Guiana. Liftoff was on Saturday, August 6, at 7:52 pm local time in Kourou (6:52 pm in Washington, D.C., 22:52 UT, 00:52 am in Paris, on Sunday, August 7 and at 7:52 am in Tokyo).

Built by Astrium using a Eurostar E3000 platform, ASTRA 1N weighed about 5,350 kg at launch. Fitted with 52 active Ku-band transponders, ASTRA 1N will be positioned at 19.2 degrees East. It will deliver DTH TV broadcast services across Europe, and offers a design life of about 15 years.

BSAT-3c/JCSAT-110R was built by Lockheed Martin Commercial Space Systems at its plant in Newtown, Pennsylvania, using an A2100 A platform. Weighing 2,910 kg at launch, it will be positioned at 110 degrees East in geostationary orbit, and offers a design life exceeding 16 years. The satellite is fitted with two sets of twelve 130 watt Ku-band transponders, and is primarily designed to provide direct TV broadcast links and telecommunications services for all of Japan.[/size]

Ariane leaves troubles behind with good launch[/size]
BY STEPHEN CLARK
SPACEFLIGHT NOW
Posted: August 6, 2011

Loaded with European and Japanese television broadcasting satellites, an Ariane 5 rocket blasted off in a ball of fire Saturday from the South American jungle and successfully deployed both payloads less than an hour later.
 
The 165-foot-tall rocket ignited its hydrogen-fueled main engine at 2252 GMT (6:52 p.m. EDT), then roared skyward seven seconds later when the launcher fired its twin solid rocket boosters. Liftoff occurred after dusk at the launch site in Kourou, French Guiana.

Arianespace, the French company overseeing the launch, postponed the mission from July 1 to replace a hydrogen valve in the rocket's first stage. An anomaly with the valve scrubbed the flight's first launch attempt.

Unfavorable upper level winds delayed the launch about one hour Saturday.

After clearing the launch pad at the Guiana Space Center, a French-run spaceport on northeast coast of South America, the Ariane 5 turned east and crossed the Atlantic Ocean in about 20 minutes.

The rocket's second stage injected both payloads in the planned oval-shaped elliptical geosynchronous transfer orbit, then released the satellites a few minutes later.

The 11,750-pound ASTRA 1N spacecraft, a satellite for European operator SES ASTRA, separated first about 27 minutes after liftoff. The Ariane 5 rocket's upper stage deployed Japan's 6,415-pound BSAT 3c/JCSAT 110R satellite 38 minutes into the flight.

Arianespace declared the launch a success, marking the Ariane's 45th straight flawless flight since 2002. The rocket's customers include commercial satellite operators, European goverments and institutions, and the International Space Station.

ASTRA 1N will be initially positioned in geosynchronous orbit at 28.2 degrees east longitude to serve the United Kingdom and Ireland. Then the satellite will move to a permanent location at 19.2 degrees east for the bulk of its 15-year service life.

From its second position, ASTRA 1N will provide direct-to-home digital and high-definition television broadcasting to Germany, France and Spain, according to SES ASTRA, the craft's operator based in Luxembourg.

The spacecraft's communications payload features 52 active Ku-band transponders. Its solar panels will stretch more than 130 feet across when fully extended in orbit.

Astrium manufactured the ASTRA 1N satellite based on the company's Eurostar E3000 spacecraft bus. The satellite is designed to generate at least 13 kilowatts of power at the end of its service life.

The BSAT 3c/JCSAT 110R satellite, a Japanese craft jointly owned by two companies, rode the Ariane 5 rocket in the lower position inside the vehicle's nose cone.

The spacecraft is designed for a 15-year tandem mission for two Japanese communications firms. Known as BSAT 3b and JCSAT 110R, the satellite was built by Lockheed Martin Corp. based on the A2011A platform.

Broadcasting Satellite System Corp., or B-SAT, and SKY Perfect JSAT Corp. will use the BSAT 3b/JCSAT 110R spacecraft on separate missions. Both companies are based in Tokyo.

B-SAT will use the spacecraft for a television broadcasting mission. B-SAT's largest shareholder is the Japanese broadcaster NHK.

The rest of the craft's capacity will be managed by SKY Perfect JSAT for other telecommunications services, including direct digital television programming.

The BSAT 3b/JCSAT 110R satellite is heading for an operational position in geosynchronous orbit along the equator at 110 degrees east longitude. It carries 24 Ku-band transponders split between its two operators.

Arianespace's next launch is set for early September with the Arabsat 5C and SES 2 commercial communications satellites.[/size]
