STS-121 crew press chat
Commander Steve Lindsey and his crew, the astronauts set to fly the second post-Columbia test flight, hold an informal news conference with reporters at Kennedy Space Center on Feb. 17. The crew is in Florida to examine hardware and equipment that will be carried on the STS-121 flight of shuttle Discovery.

House hearing on NASA
NASA Administrator Mike Griffin and his No. 2, Shana Dale, appear before the House Science Committee on Feb. 16 to defend President Bush's proposed 2007 budget for the space agency. Congressmen grill Griffin and Dale about the budget's plans to cut funding for some science programs.

STS-5: Commercial era
With the four test flights complete, NASA declared the space shuttle a fully operational program. The crews were expanded, commercial payloads were welcomed aboard and the mission plans became much more hectic. This new era began with Columbia's STS-5 flight that launched the ANIK-C3 and SBS-C commercial communications satellites from the shuttle's payload bay. Commander Vance Brand, pilot Bob Overmyer and mission specialists Joe Allen and Bill Lenoir narrate highlights from their November 1982 mission in this post-flight presentation.

STS-4: Last test flight
The developmental test flights of the space shuttle concluded with Columbia's STS-4 mission. Commander Ken Mattingly and pilot Henry Hartsfield spent a week in space examining orbiter systems and running science experiments. The 1982 flight ended on the Fourth of July with President Reagan at the landing site to witness Columbia's return and the new orbiter Challenger leaving for Kennedy Space Center. Watch this STS-4 post-flight crew presentation film.

STS-3: Unique landing
Columbia's STS-3 mission is best remembered in the history books for its conclusion -- the first and so far only landing at the picturesque Northrup Strip at White Sands, New Mexico. In this post-flight presentation film, the crew describes the highlights of the March 1982 mission and shows some of the fun they had in orbit. The commander also tells how he accidentally "popped a wheelie" before bringing the nose gear down to the runway surface.

STS-2: Columbia is a reusable spaceship
Seven months after the successful maiden voyage of space shuttle Columbia, astronauts Joe Engle and Richard Truly took the orbiter back into space on mission STS-2. The November 12, 1981 launch demonstrated that the space shuttle was the world's first reusable manned spacecraft. Although their mission would be cut short, Engle and Truly performed the first tests of the shuttle's Canadian-made robotic arm. The crew tells the story of the mission in this post-flight presentation.

Lockheed gets lightning mapper contract
LOCKHEED MARTIN NEWS RELEASE
Posted: February 22, 2006

The Lockheed Martin Advanced Technology Center (ATC) has been awarded a $2 million, 12-month contract by the NASA Goddard Space Flight Center to proceed to the formulation phase for the Geostationary Lightning Mapper (GLM) instrument that will fly on the National Oceanic and Atmospheric Administration (NOAA) GOES-R Series environmental satellites. GLM's ability to monitor convection on a global scale via lightning will provide new insight into the formation, distribution, morphology and evolution of storms, and allows investigation into the mechanisms at the core of the global water and energy cycle.

"Along with our teammates from the University of Alabama in Huntsville (UAH), we are enormously excited to be moving forward into the Geostationary Lightning Mapper formulation phase" said Earl Aamodt, Lockheed Martin GLM program manager at the ATC. "Our team has worked together since 1992 on successful lightning imaging missions, and this extensive spaceflight heritage is directly applicable to GLM. The combination of this team's experience and knowledge of GLM requirements, a proven systems engineering approach, and our detailed formulation phase plan will make this formulation phase a success."

The observation of lightning by GLM will provide a ubiquitous means of penetrating cloud tops and detecting convective activity continuously over whole continents and adjacent oceans. This lightning characteristic of clouds is inadequately measured, both temporally and spatially, by current observing systems.

With improved insight into the dynamics and life cycles of storms and weather systems, GLM will also greatly improve understanding of the fast time-scale elements of atmospheric convection. This will lead to a better understanding of the Earth as a system, which combined with long term GLM observations, will lead to significant improvements in monitoring changes in storm climatology. In addition, since intense and increasing in-cloud flashes are known to precede severe weather by tens of minutes, the real-time transmission and distribution of GLM data would greatly improve the lead-time for severe storm warnings, particularly tornadoes.

The Geostationary Operational Environmental Satellite (GOES) mission is a critical part of the U.S. satellite constellation for environmental observations, along with the Polar Operational Environmental Satellite (POES) and Defense Meteorological Satellite Program (DMSP) polar orbiting satellites -- both built by Lockheed Martin. GOES is the environmental satellite most familiar to the American public, as its images and time-lapse sequences are the primary visual material of television weather forecasts.

The GOES system -- operational since 1975 -- plays a critical role in weather and environmental forecasting. In orbit high above the equator, GOES satellites are uniquely positioned to observe the development of hazardous weather, such as hurricanes and severe thunderstorms, and to track their movement and intensity so that major losses of life and property can be reduced or avoided.

NOAA manages the GOES program and establishes the requirements, provides funding and distributes environmental data for the United States. NASA will manage the GLM instrument acquisition as a part of its support to NOAA's development of the GOES-R series of satellites.

The ATC is the research and development organization of Lockheed Martin Space Systems Company (LMSSC). LMSSC, a major operating unit of Lockheed Martin Corporation, designs, develops, tests, manufactures and operates a variety of advanced technology systems for military, civil and commercial customers. Chief products include a full-range of space launch systems, including heavy-lift capability, ground systems, remote sensing and communications satellites for commercial and government customers, advanced space observatories and interplanetary spacecraft, fleet ballistic missiles and missile defense systems.

Headquartered in Bethesda, Md., Lockheed Martin employs about 135,000 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 2005 sales of $37.2 billion.
