Atlas V chalked up another successful mission today, blasting off from Cape Canaveral in the 431 configuration (4-meter fairing, 3 solid boosters, single-engine Centaur). The payload was EchoStar 19, a commercial commsat that will be operated by HughesNet to provide high speed satellite Internet service across North America. It’s unusual to see the highly reliable but expensive Atlas V flying a commercial mission; in this case, HughesNet selected the vehicle due to rapid availability. They are currently constrained from growing their service due to all of their existing spot-beams being at full capacity; EchoStar 19 will provide 160 more spot-beams, allowing them to grow beyond their current million customers. The spacecraft is expected to enter service in March, following on-orbit testing, and will join HughesNet’s two other spacecraft, EchoStar 17 and Spaceway 3.
