Ok, thanks. I'm surprised that they don't spend the minimal dV to put the periapsis even lower for the entire upper stage stack - but I suppose they want a 2nd orbit backup attempt at deployment??

Yes, backup attempt for separation is one important constraint.

Also, the 246.9 km perigee corresponds to an ascent trajectory with only 140 km altitude during upper stage flight [1], so no fairing, payload exposed. You can't go significantly lower than these 140 km due to limitation of aerothermal friction on the payload, thus perigee height can't be significantly reduced below 250 km for Ariane 5.

This sat is being launched to help capacity for the 2014 World Cup in Brazil.

(You know how the Superbowl got 150m viewers worldwide, the World Cup final games - even at group stage - get over 1 billion. The final over 2 billion. Just saying ;D)

Hey, should be epic!
(probably a 3D event too).

Thanks for the coverage guys.
Congrats to Arianespace!
Remembering those who made the ultimate sacrifice for our rights & freedoms, and for those injured, visible or otherwise, in that fight.

A bit lost in the clouds but a good launch.

Well done ESA  :)

Go Ariane 5.

Ariane 5 delivers a record payload and completes back-to-back successes for Arianespace's launcher family

February 7, 2013 – Ariane Flight VA212

Ariane 5 provided another record payload lift performance during its year-opening dual-passenger flight this evening from the Spaceport in French Guiana, which came one day after a Soyuz success from Baikonur Cosmodrome in Kazakhstan that lofted six Globalstar second-generation constellation satellites.

Today’s launch orbited the Amazonas 3 and Azerspace/Africasat-1a telecommunications platforms, delivering a total calculated mass into geostationary transfer orbit of 10,317 kg. – which included 9,503 kg. for the two spacecraft, along with the dispenser system and integration hardware in Ariane 5’s dual payload “stack.”

“This performance demonstrates once again the pertinence of our improvement policy, which enables us to augment the capacity of our launcher while maintaining its reliability,” said Arianespace Chairman & CEO Jean-Yves Le Gall in comments at the Spaceport.

The back-to-back missions also underscored the flexibility of Arianespace’s launcher family – composed of the heavy-lift Ariane 5 utilized today at French Guiana, the medium-lift Soyuz employed in yesterday’s flight from Kazakhstan (on a mission performed by its Starsem affiliate), and the new light-lift Vega – which currently is being readied for its no. 2 Spaceport launch.

Le Gall noted that the smooth countdown to Ariane 5’s liftoff at 6:36 p.m. local time in French Guiana highlights the competence and maturity of Arianespace’s launch teams, which are trained to oversee operations with the company’s launcher family trio.

Ariane 5 deployed its Amazonas 3 and Azerspace/Africasat-1a passengers on a mission lasting just under 37 minutes.

Riding in the upper position of Ariane 5’s payload “stack,” Amazonas 3 was released first during the flight.  This satellite for the HISPASAT Group was produced by Space Systems/Loral in Palo Alto, California, and is to operate from a 61 deg. West longitude orbital slot.   

Equipped with 33 Ku-band and 19 C-band transponders, along with nine Ka-band spot beams, Amazonas 3 will provide telecommunications relay services that include direct-to-home television (DTH), corporate fixed and mobile telephone networks, and broadband capacity with coverage across the Americas, Europe, and North Africa.

Azerspace/Africasat-1a was then separated from Ariane 5, starting a career in space for the first-ever national Azerbaijan satellite launched by Arianespace. It was produced by Orbital Sciences Corporation in Dulles, Virginia, under contract to the Republic of Azerbaijan's Ministry of Communications and Information Technologies for the country's satellite operator, Azercosmos. The platform has 24 C-band transponders and 12 Ku-band transponders to deliver communications coverage over Azerbaijan, Central Asia, Europe and Africa from an orbital location of 46 deg. East longitude.

Tonight’s mission was Ariane 5’s 68th launch, and the 54th consecutive success for this workhorse Arianespace vehicle. It was designated Flight VA212, signifying the 212th liftoff of an Ariane-series launcher since 1979. Estimated orbital parameters at injection of the Ariane 5’s cryogenic upper stage were:
- Perigee: 247.2 km. for a target of 247.0 km.
- Apogee: 35,914 km. for a target of 35,891 km.
- Inclination: 5.99 deg. for a target of 6.00 deg.

Le Gall said coming up next at French Guiana is a launch targeted for April with Vega (designated Fight VV02 in Arianespace’s launcher family numbering system), using this light-lift vehicle to orbit the European Space Agency’s Proba-V satellite for monitoring of global vegetation growth, along with the VNREDSat-1A Earth observation satellite for Vietnam.

According to current Spaceport planning, the following mission will be Ariane 5’s Flight VA213, carrying the European Space Agency’s fourth Automated Transfer Vehicle for servicing of the International Space Station.

Arianespace orbits Amazonas-3 and Azerspace/Africasat-1a satellites; First Ariane 5 ECA mission in 2013 a success
Kourou, February 7, 2013

On Thursday, February 7, 2013, Arianespace successfully carried out the 54th Ariane 5 launch in a row, orbiting two telecommunications satellites: Amazonas-3 for Spanish operator Hispasat, and Azerspace/Africasat-1a for the Azerbaijani operator Azercosmos 0JSC and the Azerbaijan Ministry of Communications and Information Technologies.

First Ariane 5 launch of 2013 and a new record

Today's successful mission, the 54th in a row for the European launcher, once again proves the reliability and availability of the Ariane 5 launch system. It also confirms that Arianespace continues to set the standard for independent access to space for all operators, including national and international space agencies, private industry and governments.

The 68th launch of Ariane 5 set a new record for weight injected into geostationary transfer orbit: the launcher on this mission carried a total payload of 10,317 kg, including 9,503 kg for the two satellites, Amazonas-3 and Azerspace/Africasat-1a.

This was the first Ariane 5 launch in 2013. Its success once again illustrated the operational capability of this launcher, the only one now on the market capable of simultaneously launching two payloads.

Launching satellites for a long-standing customer and a new operator

Arianespace provides the launch services most clearly matches the requirements of all operators.

Amazonas-3 is the seventh Spanish satellite launched by Arianespace. The company first launched the Hispasat 1A and 1B satellites in 1992 and 1993, respectively, followed in 2005 and 2006 by the XTAR-Eur and Spainsat satellites for Hispasat and its subsidiary Hisdesat. Amazonas-2 was launched in 2009, followed by Hispasat 1E in 2010.

The Azerspace/Africasat-1a satellite is the first national satellite to be launched by Arianespace for the Azerbaijan Ministry of Communications and Information Technologies.

Arianespace has already launched the first satellites for 31 operators to date. 

Amazonas-3 – Azerspace/Africasat-1a 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 Thursday, February 7, 2013 at 6:36 pm local time in Kourou (4:36 pm in Washington, D.C., 21:36 UT, 10:36 pm in Paris, and 1:36 am on Friday, February 8 in Baku).

Amazonas-3 was built by Space Systems/Loral using the SSL 1300 platform and  weighed 6,265 kg at launch. It has 33 Ku-band transponders, 19 C-band transponders, and 9 Ka-band spot beams. This high-power satellite provides a wide range of telecommunications and broadband connectivity services in Europe, the Americas and North Africa. It offers a design life of 15 years. Amazonas-3 is the 43rd satellite built by Space Systems/Loral to be launched by Arianespace.

The Azerspace/Africasat-1a satellite was built by Orbital Sciences Corporation using a Star-2 platform. Weighing 3,000 kg at launch, the satellite is equipped with 24 C-band transponders and 12 Ku-band transponders. It will provide a wide range of telecommunications services for Azerbaijan, Central Asia, Europe, the Middle East and Africa.

Azerspace/Africasat-1a is the 24th satellite built by Orbital Sciences Corporation to be launched by Arianespace.
