Title Ron Dittemore and Michael Kostelnik
Full Description Ronald D. Dittemore (right), a 26-year NASA veteran, announces his intention to step aside as the Space Shuttle Program Manager at the Johnson Space Center in Houston to pursue other opportunities. Also pictured at the Washington, DC announcement is Michael Kostelnik, Deputy Associate Administrator for the Space Shuttle and International Space Station Programs. Dittemore, who has served as the Shuttle Program Manager for more than four years, will remain in his current position until the Columbia Accident Investigation Board finishes its investigation and a complete "Return to Flight" path has been established. Dittemore retired recently, he had publicly planned to do so before the accident.

Fires in British Columbia
Title Fires in British Columbia
Description The 2003 fire season was another very active one for western North America, especially in the Canadian province of British Columbia where some 620,000 acres of forest were consumed in almost 2,500 fires. Here the Rocky Mountains have both lofty, snow-capped peaks and long, narrow valleys that create special conditions and problems with air quality from these smoky fires. This image taken by the crew of the International Space Station on August 20, 2003, illustrates how smoke has become trapped in valleys. Normally air temperature decreases with altitude, in other words, the higher up you are, the colder it is. Warmer, more buoyant air near the surface of the Earth usually rises into the atmosphere, carrying away air pollutants such as smoke. However, sometimes the "higher equals colder" relationship breaks down, for example, here in the northern Rockies, where light winds and cold air drainage from the higher elevations have created "temperature inversions," making the air in the valley colder and denser than the air at the mountain peaks. The cold dense air does not rise, but intsead stays trapped—along with the smoke—in the valleys. Note how the snowy peaks of the mountains are relatively smoke-free while the long, north-south valleys of Kootenay Lake and Columbia River are filled with trapped aerosols from the plumes of the large fires situated to the southwest. Meanwhile shifting winds have now swept the bulk of the plumes southeastward over the Columbia River Basin of Washington. Astronaut photograph ISS007-E-13281 was taken August 20, 2003 with a Kodak DCS760 digital camera equipped with an 50mm lens and provided by Michael Trenchard (Lockheed Martin / Earth Observations Laboratory, Johnson Space Center). The International Space Station Program supports the laboratory to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth Website.
