Cape Canaveral Air Force Station, FL -- Lockheed Martin (NYSE: LMT) is completing final preparations for Monday’s launch of a commercial telecommunications satellite aboard an Atlas V booster provided by United Launch Alliance. The launch window opens at 4:12 p.m. EDT Monday and extends until 5:12 p.m. The launch can be viewed live at www.ulalaunch.com beginning at 3:51 p.m. EDT.

Lockheed Martin Commercial Launch Services is under contract to ICO Global Communications (Holdings) Limited (NASDAQ: ICOG) to place the ICO G1 spacecraft into orbit. The spacecraft was built by Space Systems/Loral. The spacecraft will deliver advanced nationwide mobile interactive media services to portable and handheld devices.

“This is a vitally important launch to ICO and we’re proud to have been selected as the launch services partner,” said David Markham, president of Lockheed Martin Commercial Launch Services. “This launch also will demonstrate the flexibility of the Atlas program that can be applied to the commercial market as we continue to seek one to two commercial customers per year.”

The ICO G1 satellite is over 27 feet tall, features a 12-meter unfurlable mesh S-band reflector, provides 16 kilowatts of power with solar arrays that span over 100 feet when deployed, and weighs in at approximately 6,634 kg fueled, making it the heaviest satellite ever launched aboard an Atlas V booster. The spacecraft will be located at 92.85 degrees west, providing ubiquitous coverage over the United States.

ICO Global Communications (Holdings) Limited is a satellite communications company developing an advanced next-generation hybrid media system, combining both satellite and terrestrial communications capabilities.  ICO is deploying a mobile interactive media service known as ICO mim™.  ICO mim™ will combine ICO’s unique interactive satellite capability with nationwide coverage to deliver a new level of navigation, enhanced roadside assistance and the ultimate mobile video experience, including 10-15 live channels of premium television content.  ICO is based in Reston, Virginia.

Lockheed Martin Commercial Launch Services, which markets the Atlas V to commercial customers worldwide, is a unit of Lockheed Martin Space Systems Company.  Lockheed Martin Space Systems Company, a major operating unit of Lockheed Martin Corporation, designs, develops, tests, manufactures and operates a full spectrum of advanced-technology systems for national security, civil and commercial customers. Chief products include human space flight systems; a full range of remote sensing, navigation, meteorological and communications satellites and instruments; space observatories and interplanetary spacecraft; laser radar; fleet ballistic missiles; and missile defense systems.

Headquartered in Bethesda, Md., Lockheed Martin employs about 140,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. The Corporation reported 2007 sales of $41.9 billion. 

Weather Overview:

Overall probability of violating weather constraints: 30%

Primary concern(s):Ground Winds, Thick Clouds

 

Overall probability of violating weather constraints for 24 hour delay: 60%

Primary concern(s):Ground Winds, Thick clouds, Disturbed Weather

 

The cold front that transited the peninsula Sunday is well to the South with high pressure building into the peninsula.Winds are expected to be gusting in the mid to upper teens by the afternoon hours and increasing near the window gusting in the low to mid 20s, below the 29 kt liftoff constraint.Remnant moisture over the peninsula from the frontal boundary continues a small threat of a thick cloud rule violation.The primary concerns for launch day are gusty winds and a risk of thick clouds associated with the remnant clouds transiting the peninsula.In the event of a 24 hour delay, a secondary surge of gusty winds associated with a strengthening low pressure system in the Atlantic results in gusty winds late Monday and persisting through Wednesday.There is an increased threat of a thick cloud rule and a disturbed weather rule violation associated with an upper level disturbance over the peninsula and showers over the Atlantic.
