The rocket shed its twin strap-on boosters and nose cone, then the rocket\u2019s upper stage disengaged for an engine burn to guide the DirecTV and Sky Mexico payloads into orbit.<\/p>\n<p>Stacked together with a dual-payload adapter during launch, DirecTV 15 and Sky Mexico 1 deployed from the Ariane 5\u2019s upper stage one at a time, completing the operational part of the flight sequence about 38 minutes after liftoff.<\/p>\n<p>Arianespace hailed the launch as a success, completing the launch company\u2019s fourth mission of the year. It was the 79th flight of an Ariane 5 rocket since 1996, and the launcher\u2019s 65th straight success.<\/p>\n<p>The rocket aimed for an geosynchronous transfer orbit with a high point of 22,236 miles, a low point of 155 miles and an inclination of 6 degrees. Stephane Israel, Arianespace\u2019s chairman and CEO, said data from the Ariane 5 rocket showed the mission hit its target.<\/p>\n<p>Spacecraft officials said ground controllers received signals from both satellites, confirming their health after the launch.<\/p>\n<p>\u201cThank you Arianespace for the best and most reliable launcher in the world,\u201d said Phil Goswitz, DirecTV\u2019s senior vice president of space, communications and video, in remarks after the launch. \u201cWow, a double header.

Goswitz said in-orbit testing of DirecTV 14\u2019s advanced broadcast instruments is nearing completion.<\/p>\n<p>\u201cWith DirecTV 14 and now DirecTV 15, we\u2019ve significantly expanded our pipe, and it will give us substantial capacity to lead in 4K linear services, especially linear sports, which we think will be spectacular,\u201d Goswitz said in an interview from the French Guiana launch site.<\/p>\n<p>DirecTV subscribers with Ultra HD televisions will see channels from DirecTV 15 with four times as many pixels as a 1080p high-definition signal.<\/p>\n<p>Goswitz said Hollywood movie studios are beginning to film in 4K Ultra HD, and DirecTV customers will initially see the ultra-sharp programming in video-on-demand options. DirecTV expects live sports broadcasts and cable channels to follow the lead of the studios in adopting 4K Ultra HD.<\/p>\n<p>\u201cWe\u2019re going through the same kind of dynamic that we had with the rollout of high-definition services,\u201d Goswitz said. \u201cThere\u2019s additional investment, and everyone is going to have to step up to that investment. They\u2019re a little reluctant to do so at the start, and that\u2019s part of the process, but they are \u2014 starting with the studios \u2014 starting to announce the availability of 4K Ultra HD movies, as well as introducing high dynamic range. That\u2019s not only better resolution, but wider color space and higher dynamic range from dark to brightness.\u201d<\/p>\n<p>Video-on-demand in 4K Ultra HD is available to customers with an Ultra HD television and existing receivers, according to Goswitz. Subscribers will need an upgraded receiver to access live transmissions.<\/p>\n<p>The spacecraft\u2019s Ku-band instrumentation will offer backup capacity for DirecTV\u2019s existing services in case older satellites need to be replaced.<\/p>\n<p>\u201cIt\u2019s essentially \u2014 by design \u2014 a very flexible satellite, but its primary mission will be national Ultra HD and additional high-definition services for our main coverage area,\u201d Goswitz said.<\/p>\n<figure id=\"attachment_6616\" aria-describedby=\"caption-attachment-6616\" style=\"width: 621px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-6616\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2015\/05\/17668756838_0ccbc5d530_b.jpg\" alt=\"Technicians prepare the Sky Mexico 1 satellite for launch at the Guiana Space Center.

The California-based satellite operator owns 41 percent of Sky Mexico, which is majority owned by Televisa, a Mexican media company.<\/p>\n<p>Sky Mexico 1 is the company\u2019s first dedicated satellite, doubling Sky Mexico\u2019s broadcast capacity. Sky Mexico currently leases transponders from the Intelsat 21 satellite stationed over the Atlantic Ocean.<\/p>\n<p>Built by Dulles, Virginia-based Orbital ATK, the 7,014-pound \u2014 3,181-kilogram \u2014 Sky Mexico 1 spacecraft will raise its orbit to geostationary altitude over the next week and extend its reflectors and solar panels.<\/p>\n<p>Officials say Sky Mexico 1 will be operational by the end of June. Sky Mexico 1\u2019s home will be at 78.8 degrees west longitude.<\/p>\n<p>\u201cThis satellite is Sky Mexico and DirecTV\u2019s own spectrum, so it\u2019s a satellite we own and are not leasing,\u201d Goswitz said. \u201cWe are effectively doubling the capability of the business by going from 24 to 48 (transponders). We\u2019re adding 24 additional transponders which will allow for substantial growth. (Sky Mexico) will be able to significantly change their competitive position and greatly improve their offerings.\u201d<\/p>\n<p>Sky Mexico broadcasts directly to 5.9 million customers in Mexico, Central America and the Caribbean.<\/p>\n<p>Arianespace\u2019s next launch is set for June 22 with the lightweight solid-fueled Vega rocket, which will carry up the Sentinel 2A land imaging satellite for the European Space Agency and the European Commission.<\/p>\n<p>The next Ariane 5 flight is scheduled for July 2 with the Star One C4 telecom satellite for Brazil and the MSG-4 weather observatory for Eumetsat, operator of Europe\u2019s meteorological satellites.<\/p>\n<p><b><i>Email the author.<\/i><\/b><\/p>\n<p><em><strong>Follow Stephen Clark on Twitter: @StephenClark1.<\/strong><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>An Ariane 5 rocket fired into space from a tropical spaceport in French Guiana on Wednesday, successfully delivering two television broadcast satellites into high-altitude orbits for DirecTV and Sky Mexico.
