Oh, I have slipped the surly bonds of earth and danced the skies on laughter-silvered wings; sunward I’ve climbed, and joined the tumbling mirth of sun-split clouds – and done a hundred things you have not dreamed of – wheeled and soared and swung high in the sunlit silence.
Hov’ring there, I’ve chased the shouting wind along, and flung my eager craft through footless halls of air. Up, up the long, delirious, burning blue I’ve topped the windswept heights with easy grace where never lark, or even eagle flew.
And while with silent, lifting mind I’ve trod the high untrespassed sanctity of space, put out my hand, and touched the face of God.
When the decision was made to scale-back space exploration after Apollo 17, I managed to remain interested. Skylab, Apollo-Soyuz, the Vikings, theVoyagers - I followed all of them. Ah, but the Shuttle Program hooked me from the start. I skipped work to rush out to Andrews Air Force Base to see Enterprise piggy-backed on a 747. I followed the first few Shuttle missions religiously. I swore that one day I'd make it down to Kennedy Space Center to see a launch in-person. Unfortunately, as other things preoccupied me (grad school) and as the Shuttle Program's very success made each ensuing launch seem more mundane, like most people I began to take the Shuttle Program for granted. The Challenger Tragedy in 1986 wrenchingly brought my attention back to the program for a time, but as mistakes were amended and the program once again became predictably dependable, I drifted away. Ironically, the less I paid attention to Shuttle missions, the more I came to depend on the work the astronauts were doing.
As a geographer with training in remote
sensing, I used Apollo photographic imagery of the earth and satellite
imagery from the various generations of Landsat. Yet, throughout
the 90s I came to rely more and more on the quality, number, and human
touch of imagery from Shuttle missions, especially in my teaching.
I use countless images of the earth as seen from the Shuttle in Power Point
presentations to illustrate important concepts in geomorphology, climatology,
and cultural and economic geography for my students. Of course, the
temptation is to look on Shuttle mission imagery as "product" and to forget
that there is a highly-trained man or woman behind the lense of the camera,
floating in weightlessness at a Shuttle's view ports, waiting for the right
shot to pass underneath. The mission specialists aboard STS-107 were
just such men and women. As part of their mission goals, they trained
for long hours on the best digital video and still cameras and took some
stunning imagery of the earth environment (as the images below attest).
Until tragedy strikes, we tend to forget that such a seemingly simple task
as gathering images from the Shuttle platform is part of a very dangerous
job. I didn't personally know any of Columbia's crew, but
I feel a bond with all of them nonetheless. Each of the crew members
of STS-107 knew the risks they were taking, yet took the gamble and gladly
signed-on to take the greatest ride that the modern world has to offer.
Does that make them heroes? They probably wouldn't think so.
They were the best Western Civilization and American and Israeli culture
have to offer. They reached the pinnacle of achievement in their
chosen field of endeavor. They died satisfying their fondest desires,
doing what they loved. Would I have made the same choice they did?
In a heartbeat.

Columbia, the oldest orbiter in the Shuttle fleet and the first to fly into earth orbit in 1981, was named after the Boston, Massachusetts-based sloop captained by American Robert Gray. On May 11, 1792, Gray and his crew maneuvered the Columbia past the dangerous sandbar at the mouth of a river extending more than 1,000 miles through what is today south-eastern British Columbia, Canada, and the Washington-Oregon border; the river was later named after the ship. Gray also led Columbia and its crew on the first American circumnavigation of the globe. Other sailing ships have further enhanced the luster of the name Columbia: the first U.S. Navy ship to circle the globe bore that title, as did the command module for the first lunar landing mission, Apollo 11. "Columbia" was the name applied to the feminine personification of the United States and was derived from that of another famous explorer, Christopher Columbus. In the day-to-day world of official Shuttle operations, Space Shuttle orbiters go by more prosaic designations; Columbia was commonly refered to as OV-102, for Orbiter Vehicle-102.

Upgrades and Features
Columbia was the first on-line orbiter to undergo the scheduled inspection and retrofit program. After it completed mission STS-40, it was transported on August 10, 1991 to Shuttle contractor Rockwell International's Palmdale, California assembly plant. The oldest orbiter in the fleet underwent approximately 50 modifications, including the addition of carbon brakes, drag chute, improved nose wheel steering, removal of development flight instrumentation, and an enhancement of its thermal protection system. The orbiter returned to Kennedy Space Center on February 9, 1992 to begin preparing for mission STS-50 in June of that year. On October 8, 1994, Columbia once again was transported to Palmdale California for its first Orbiter Maintenance Down Period (OMDP). On September 24, 1999, Columbia returned to Palmdale California for its second OMDP, during which workers performed more than 100 modifications on the vehicle. Columbia was the second orbiter outfitted with the multi-functional electronic display system (MEDS) or "glass cockpit".

Shreveport, LA doppler radar images
Radar out of Shreveport, Louisiana caught Columbia's debris cloud as it crossed the Texas-Louisiana border. On this animated radar loop (l), the debris appears as a light blue streak between the labels for Nacogdoches, TX and Natchitoches, LA. The local radar image for Shreveport (r) clearly shows the extent of the debris cloud from Columbia between Tyler, TX and Alexandria, LA
