Stephen Price from Lockheed Martin Space Systems Company kicks off the ‚Äö√Ñ√∫Seeking Signs of Life‚Äö√Ñ√π Symposium, celebrating 50 Years of Exobiology and Astrobiology at NASA, Thursday, Oct. 14, 2010, at the Lockheed Martin Global Vision Center in Arlington, Va. NASA has been researching life in the universe since 1959, asking three fundamental questions: "How does life begin and evolve?"‚ "Is there life beyond Earth and, if so, how can we detect it?" and "What is the future of life on Earth and in the universe?"

NEW ORLEANS -- Associate Administrator for Space Operations Bill Gerstenmaier and Manny Zulueta, Lockheed Martin vice president and site executive at NASA's Michoud Assembly Facility in New Orleans, watch the progress of the Space Shuttle Program's last external fuel tank, ET-122, as it is being transported from the facility to the Pegasus Barge. The tank will travel 900 miles by sea to NASA's Kennedy Space Center in Florida secured aboard the barge, offloaded and moved to Kennedy's Vehicle Assembly Building where it will be integrated to space shuttle Endeavour for the STS-134 mission to the International Space Station. The tank, which is the largest element of the space shuttle stack, was damaged during Hurricane Katrina in August 2005 and restored to flight configuration by Lockheed Martin Space Systems Company employees. STS-134, targeted to launch Feb. 2011, currently is scheduled to be the last mission in the Space Shuttle Program. Photo credit: NASA/Kim Shiflett

KENNEDY SPACE CENTER, FLA. - Lockheed Martin Vice President/Associate Program Manager Brian Duffy (second from left) and NASA/Kennedy Space Center Director Roy Bridges (center) share a laugh with student participants in the 2003 Southeastern Regional FIRST Robotic Competition. The competition is being held at the University of Central Florida (UCF) in Orlando, March 20-23. Forty student teams from around the country are participating in the event that pits team-built gladiator robots against each other in an athletic-style competition. The teams are sponsored by NASA/Kennedy Space Center, The Boeing Company/Brevard Community College, and Lockheed Martin Space Operations/Mission Systems for the nonprofit organization For Inspiration and Recognition of Science and Technology, known as FIRST. The vision of FIRST is to inspire in the youth of our nation an appreciation of science and technology and an understanding that mastering these disciplines can enrich the lives of all mankind.

CAPE CANAVERAL, Fla. – Larry Price, Lockheed Martin Space Systems deputy program manager for NASA's Orion spacecraft, joins Sierra Nevada Corporation, or SNC, Space Systems, as the company announces the steps it will take to prepare for a November 2016 orbital flight of its Dream Chaser spacecraft from Florida’s Space Coast. The steps are considered substantial for SNC and important to plans by NASA and Space Florida for Kennedy Space Center’s transformation into a multi-user spaceport for both commercial and government customers. SNC said it plans to work with United Launch Alliance, or ULA, to launch the Dream Chaser spacecraft into orbit atop an Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station intends to land the winged spacecraft at Kennedy’s 3.5-mile long runway at the Shuttle Landing Facility lease office space at Exploration Park, right outside Kennedy’s gates and process the spacecraft in the high bay of the Operations and Checkout Building at Kennedy, with Lockheed Martin performing the work.

The teams are sponsored by NASA/Kennedy Space Center, The Boeing Company/Brevard Community College, and Lockheed Martin Space Operations/Mission Systems for the nonprofit organization For Inspiration and Recognition of Science and Technology, known as FIRST. The vision of FIRST is to inspire in the youth of our nation an appreciation of science and technology and an understanding that mastering these disciplines can enrich the lives of all mankind.

CAPE CANAVERAL, Fla. – Jim McCarthy right, president of the National Space Club-Florida Chapter, thanks Larry Price, deputy manager of the Orion Program for the Lockheed Martin Space Systems Company, for his presentation to members and guests at the Radisson Resort at the Port in Cape Canaveral, Fla. Price’s presentation included an overview of Orion processing, testing and preparations for Exploration Flight Test 1. Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans. It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities. The first unpiloted test flight of Orion is scheduled to launch in 2014 atop a Delta IV Heavy rocket and in 2017 on NASA’s Space Launch System rocket. For more information, visit www.nasa.gov_orion.

CAPE CANAVERAL, Fla. -- A tugboat pulls the Pegasus Barge carrying the Space Shuttle Program's last external fuel tank, ET-122, toward the Turn Basin at NASA's Kennedy Space Center in Florida. The tank traveled 900 miles by sea from NASA's Michoud Assembly Facility in New Orleans. In the background, space shuttle Discovery is on Launch Pad 39A awaiting liftoff on the STS-133 mission to the International Space Station. Next, the tank will be offloaded and moved to the Vehicle Assembly Building where it eventually will be attached to space shuttle Endeavour for the STS-134 mission to the station. STS-134, targeted to launch in Feb. 2011, currently is scheduled to be the last mission in the Space Shuttle Program. The tank, which is the largest element of the space shuttle stack, was damaged during Hurricane Katrina in August 2005 and restored to flight configuration by Lockheed Martin Space Systems Company employees.

CAPE CANAVERAL, Fla. -- Freedom Star, one of NASA's solid rocket booster retrieval ships, pulls the Space Shuttle Program's last external fuel tank, ET-122, toward NASA's Kennedy Space Center in Florida. The tank traveled 900 miles by sea from NASA's Michoud Assembly Facility in New Orleans aboard the Pegasus Barge. After reaching the Turn Basin at Kennedy, the tank will be offloaded and moved to the Vehicle Assembly Building where it eventually will be attached to space shuttle Endeavour for the STS-134 mission to the International Space Station. STS-134, targeted to launch in Feb. 2011, currently is scheduled to be the last mission in the Space Shuttle Program.

CAPE CANAVERAL, Fla. -- To commemorate the history of the Space Shuttle Program's last external fuel tank, its intertank door is emblazoned with an ET-122 insignia. The tank is in the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida after traveling 900 miles by sea from NASA's Michoud Assembly Facility in New Orleans aboard the Pegasus Barge. It eventually will be attached to space shuttle Endeavour for the STS-134 mission to the International Space Station. STS-134, targeted to launch in Feb. 2011, currently is scheduled to be the last mission in the shuttle program. The tank, which is the largest element of the space shuttle stack, was completed in 2002, modified during Return to Flight operations in 2003 and 2004, damaged during Hurricane Katrina in 2005, and then restored to flight configuration by Lockheed Martin Space Systems Company employees in 2008 at NASA's Marshall Space Flight Center in Alabama.
