Lockheed Martin release
LOCKHEED MARTIN DELIVERS THIRD RETURN TO FLIGHT EXTERNAL TANK TO NASA
NEW ORLEANS, LA., June 13, 2005 -- Lockheed Martin’s (NYSE: LMT) third
retrofitted Space Shuttle External Tank, designated ET-119, departed
today via ocean-going barge for a five-day trip to Kennedy Space Center
(KSC). NASA will assign the tank to one of its upcoming Return to
Flight shuttle missions.
Lockheed Martin delivered the tank to NASA on June 12 after waiting
three days for Tropical Storm Arlene to clear the Gulf of Mexico.
Lockheed Martin designs and builds the External Tank at the NASA Michoud
Assembly Facility in New Orleans.
In addition to the design and process improvements included on the first
two Return to Flight tanks delivered to NASA, ET-119 features a heater
installed on the Liquid Oxygen (LO2) feedline bellows. The heater is
designed to prevent the formation of frost or ice that may form on the
bellows, a bare metal component of the feedline that allows the
structure to flex during launch and ascent. The feedline carries
cryogenic LO2 at a temperature of minus 297 degrees F.
Lockheed Martin Space Systems – Michoud Operations designs and builds
large aluminum and composite structures for aerospace and other
applications at the Michoud Assembly Facility.
Photos of the ET-119 rollout are available at
www.lockheedmartin.com/Michoud under “Michoud Image Gallery.”
