Atlas 5 launches EchoStar 19

WASHINGTON — A United Launch Alliance Atlas 5 efficiently launched a broadband satellite tv for pc for EchoStar Dec. 18 on ULA’s ultimate mission of the 12 months, placing EchoStar again on observe to jump-start subscriber progress for its satellite tv for pc web service.

The Atlas 5 431 lifted off at 2:13 p.m. Jap from Cape Canaveral, Florida. The launch was postponed due to a problem with the automobile’s avionics that triggered a maintain simply 74 seconds earlier than the unique liftoff time of 1:27 p.m. Controllers ultimately determined to manually monitor the difficulty that triggered the maintain.

The rescheduled launch then went as deliberate, with the EchoStar 19 satellite tv for pc separating from the Centaur higher stage 32 minutes after liftoff. The Atlas 5 positioned EchoStar 19 right into a super-synchronous switch orbit with an apogee of about 65,000 kilometers, from which the satellite tv for pc will maneuver to geostationary orbit at 109 levels west.

EchoStar 19, often known as Jupiter 2, was constructed by House Methods Loral and is designed to supply broadband Web entry to clients of the corporate’s HughesNet service in North America. Germantown, Maryland-based Hughes expects to succeed in a throughput of 220 gigabits per second with EchoStar 19, a rise of 58 gigabits per second because of enhancements to the satellite tv for pc and the bottom phase. The Ka-band spot-beam spacecraft gives room for extra subscribers to HughesNet client broadband, because the near-entirety of EchoStar 17/Jupiter 1’s marketable capability is already spoken for.

In August 2015, EchoStar switched the launch of EchoStar-19 from Arianespace to ULA in an effort to launch the satellite tv for pc sooner. The corporate is awaiting yet one more launch this 12 months, of EchoStar 21 aboard an Worldwide Launch Providers Proton rocket. Beforehand anticipated to launch in mid-2016, the mission slipped to late December as Proton producer Khrunichev sought to research a second stage anomaly through the June launch of Intelsat 31.

EchoStar can also be awaiting the launch of the Ku-band broadcast satellite tv for pc EchoStar-23 on a SpaceX Falcon 9 rocket. That mission was initially anticipated in August earlier than delays compounded by the Sept. 1 Amos-6 explosion pushed that flight into 2017.

The launch was the twelfth and ultimate mission of the 12 months for ULA. That whole consists of eight Atlas 5 and 4 Delta 4 launches. The Atlas 5 launches featured three business missions: along with the EchoStar 19 launch, an Atlas 5 launched the WorldView-4 satellite tv for pc Nov. 11, and one other launched a Cygnus cargo spacecraft for Orbital ATK in March. ULA and Lockheed Martin Industrial Launch Providers, which markets the Atlas commercially, have sought lately to enroll extra business clients for the Atlas 5.

This launch was simply the third of the Atlas 5 431 variant, which makes use of a payload fairing 4 meters in diameter and three stable rocket boosters. The Atlas 5 431 beforehand launched the Inmarsat 4-F1 satellite tv for pc in March 2005 and Intelsat 14 in November 2009. Whereas phrases of this launch weren’t disclosed, the Atlas 5 431 has an approximate checklist value of $132 million for normal business missions to geostationary switch orbit, in accordance with ULA’s RocketBuilder web site.

Present manifests name for about 14 ULA missions in 2017, of which as much as 10 might be Atlas 5 launches, together with one other business launch of a Cygnus cargo spacecraft. Three Delta 4 launches are additionally scheduled, in addition to one of many ultimate launches of the Delta 2, carrying the primary Joint Polar Satellite tv for pc System spacecraft.
