Spanish satellite soars aboard Atlas 2AS rocket

With ideal weather and a ground liquid oxygen leak of no consequence, officials gave the "go" to count down for liftoff at 6:04 p.m. EDT (2204 GMT), the very opening of the day's launch window.
Riding the thrust of its liquid-fueled Rocketdyne MA-5A engines and strap-on ATK Thiokol solid boosters, the 522,500-pound rocket crept off Cape Canaveral's launch pad 36A and into a clear blue Florida sky.
Within 10 minutes, the Pratt & Whitney-powered Centaur upper stage and attached Hispasat 1D satellite payload had reached a temporary orbit around the planet. After taking a 14-minute break, the Centaur was in position to fire again, propelling its 7,165-pound cargo into a highly-elliptical supersynchronous transfer orbit.
Twenty-nine minutes after it began, the launch had a joyful conclusion for Lockheed Martin and its customers as Hispasat 1D was released to fly on its own. It was the 62nd consecutive successful Atlas launch dating back to 1993.
"We're very happy to congratulate ILS and Hispasat for this successful launch," said Yves De LeSerre, executive vice president at Alcatel Space, which built Hispasat 1D. "I want to thank very deeply all the teams who have worked for that, the ILS team, the Hispasat team and the Alcatel Space team. I'm very grateful for the way in which those teams have cooperated, and that's certainly one major reason of this success."
"I'm very happy, once again (for) the work we have been doing with ILS and Alcatel, so I thank both of them for these three years of working, which have been successful today," added Hispasat CEO Jacinto Garcia Palacios. "For Hispasat it is a very important milestone in the development of the company, so thanks to all the teams, including the Hispasat team who have been working with all of you during these years."
Built to last 15 years, the new craft will provide digital TV and data transmission services through its 28 Ku-band transponders. Its coverage area includes Europe, North Africa, the Middle East and a trans-Atlantic reach to parts of North and South America.
The satellite will join Hispasats 1A, 1B and 1C, and be ready to replace the aging 1A and 1B when they are expected to be retired late next year. Hispasat 1C was launched aboard an Atlas two years ago.
The launch was the 25th flight of an Atlas 2AS rocket, the Atlas 2-series vehicle with four strap-on solid rocket motors. Five more Atlas 2AS vehicles are left to fly over the next two years. All previous Atlas 2AS launches have been successful since debuting in December 1993.
For this launch, the image of an American flag and the words "United We Stand" were put on one of the solid rocket boosters in remembrance of last year's attack on America.
"At the request of one of our employees, Greg Lackore, he came to us and he suggested since we are launching close to September 11 we could put a flag on one of the solid rocket boosters," said Atlas Launch Director Adrian Laffitte. "That is to recognize and remember the events of September 11."
The next Atlas mission is scheduled for the evening of November 20 when the final Atlas 2A rocket will launch NASA's Tracking and Data Relay Satellite-J, or TDRS-J.
