New satellite launched for DISH Network subscribers

With a booming burst of fire and smoke, a Sea Launch Zenit 3SL rocket began its journey toward orbit from the tranquil Pacific Ocean today on a mission to deploy a communications satellite that will become part of DISH Network's space-based broadcasting system.
The liftoff had been postponed for a week after two separate issues plagued the launch team during earlier attempts. First, a hold was called in the final minutes of the countdown last Wednesday because of an undisclosed problem with a ground support system. Strong ocean currents further delayed the launch from the weekend. The rocket had to be lowered from its launch mount twice during the scrubs.
On its 19th flight, the modified version of Ukraine's Zenit rocket worked flawlessly. The first two stages of the launcher fired as planned to propel the Block DM upper stage and EchoStar 10 payload into a suborbital trajectory. The Block DM then assumed control of the mission to first put itself into a low parking orbit, then to finish the task of deploying EchoStar 10 in its planned elliptical orbit.
It took just over one hour to successfully complete the job of placing the EchoStar 10 spacecraft into its targeted geosynchronous transfer orbit. More than a half-hour later, Earth-bound controllers heard the first signals from the 9,553-pound satellite to confirm the high-powered broadcasting platform was in good health following its fiery launch.
EchoStar 10 was delivered into an orbit with a high point of around 22,207 miles, about seven miles higher that the pre-launch predictions, a low point right on the planned mark of 1,047 miles, and an inclination of zero degrees to the Equator. The craft will use
on-board thrusters in five burns to gradually nudge its path around the
planet higher until it is circularized at an altitude of 22,300 miles
within about seven to ten days.
Expectations are that EchoStar 10 will be deemed operational by late April, said EchoStar vice president of satellite programs Rohan Zaveri.
Built by Lockheed Martin, EchoStar 10 carries a Ku-band communications payload tailored for direct-to-home broadcasting needs. The new satellite's capability will add to EchoStar's existing lineup of core television channel offerings on the company's DISH Network system that currently has a roster of over 12 million customers across the United States.
"I would tell our customers to look for good things," Zaveri said in a post-launch TV interview. "It was a great day and a spectacular launch."
DISH Network provides hundreds of audio and video channels - ranging from national cable networks to local television affiliates - directly to homes, offices and schools nationwide. EchoStar 10 will work with its nine counterparts in space to help expand those programming choices over its planned 15-year service life.
EchoStar 10 will specifically work to provide programming to individual markets across the United States. The spacecraft features 10 uplink spot beams that will be pointed at six locations inside the continental United States and four additional sites in Alaska, Hawaii, Puerto Rico, and Cuba. The satellite's 49 downlink spot beams will be pointed at over four dozen locations inside the United States, Puerto Rico, and Cuba, according to filings with the Federal Communications Commission.
"We are pleased with the success of the launch mission and want to thank Sea Launch and Lockheed Martin for their efforts for launching our satellite," Zaveri said in post-launch remarks. "We look forward to testing and use of the satellite within the next few months."
Wednesday's launch was the first of 2006 for Sea Launch - an international launch services provider formed in 1995 by Boeing, RSC Energia, the Ukrainian rocket-builders Yuzhnoye and Yuzhmash, and Norwegian ship-builder Kvaerner. Five more missions are planned for this year, Sea Launch says.
"Like our colleagues in the launch industry, we are excited at the prospect of a promising upturn in the launch services market," Maser said. Sea Launch flew four times last year, and added nine new commercial contracts to its ever-growing backlog.
