A Lockheed Martin-built Atlas 5 rocket roared into space
today, launching a new American satellite that will provide satellite broadcast
services for television connoisseurs across the United States.
Sitting atop its 196-foot booster, the commercial satellite
AMC-16 left Earth at 7:07 a.m. EST (1207 GMT) in a flight staged from Launch
Complex 41 at Cape Canaveral Air Force Station in Florida.
About 4.5 minutes after liftoff, the
Atlas 5 booster engine cut off and its Centaur upper stage ignited for an
11-minute burn, the first of two maneuvers to propel AMC-16 into its
geosynchronous orbit. Spacecraft separation occured smoothly about 8:55
a.m. EST (1355 GMT).
"Looks like we shot a
bullseye," a launch commentator said.
Built by Lockheed Martin for Princeton, New Jersey-based
satellite provider SES AMERICOM, the AMC-16 spacecraft is designed to provide
direct-to-home entertainment and broadband services across the United States for
satellite television customers under EchoStar's DISH Network.
Today's
flight was marketed by McLean, Virgina's International Launch Services, which
also marketed the launch of AMC-16's sister satellite AMC-15. That spacecraft launched atop a Russian Proton rocket from Baikonur Cosmodrome on Oct.
14.
Before
liftoff, ILS president Mark Albrecht said AMC-16, and its fellow satellite
AMC-15, will provide a tremendous enhancement of the direct broadcasting
services offered by SES AMERICOM.
Launch
officials worked a few issues building up to launch, including a battery glitch
and threatening weather that delayed the flight from its planned 4:41 a.m. (0941
GMT) launch time.
Two
minutes before liftoff, the launch went into an unplanned hold when its
computers controlling the countdown detected problems associated with a booster
valve. No sooner had engineers determined the valve was functioning properly
when high winds again prompted a countdown hold.
Mission controllers had a two-hour and 48-minute launch
window to fly the Atlas 5 rocket and
satellite. The Atlas 5 launch caps a string of successful flights with Atlas family
launch vehicles.
The
AMC-16 satellite is a
veritable twin of its AMC-15 predecessor, both of which are part of SES
AMERICOM's AMERICA2Home program. The 8,962-pound (4,065-kilogram) satellite
features 24 active Ku-band transponders and 12 programmable Ka-band spot beams,
with a design lifetime of about 15 years.
"In
terms of Ka-band, this flight shows it's really coming of age and being used in
a substantial way," said Andreas Georghio, senior vice president of business
development for SES AMERICOM, in a Dec. 16 interview. "We have a major player in the industry,
EchoStar, making the Ka-band a significant part of their capacity to reach
consumer homes."
Today's
flight marked the fourth launch of an Atlas 5 rocket by as well as the fourth
mission lofted by ILS for SES AMERICOM this year. It was the tenth ILS mission
this year.
