It will become the centerpiece of scientific research on the ISS, with five equipment racks aboard to provide essential functions for station systems, including high data-rate communications, and to maintain the station's orientation using control gyroscopes launched earlier. Additional equipment and research racks will be installed in the laboratory on subsequent Shuttle flights

KENNEDY SPACE CENTER, FLA. -- In the Space Station Processing Facility, U.S. Rep. Dave Weldon (center) and his chief of staff Dana Gartzke (second from left) get a close-up look at the interior of the U.S. Lab, called "Destiny." Thomas R. "Randy" Galloway (second from right), with the Space Station Hardware Integration Office, helps with their familiarization of the equipment. They are joined (far left and right) by workers from Boeing. Weldon is on the House Science Committee and vice chairman of the Space and Aeronautics Subcommittee. Destiny is scheduled to be launched on Space Shuttle Endeavour in early 2000.

KENNEDY SPACE CENTER, FLA. -- In the cockpit of the orbiter Atlantis, which is in the Orbiter Processing Facility, Laural Patrick (left), a systems engineer with MEDS, points out a feature of the newly installed Multifunction Electronic Display Subsystem (MEDS), known as the "glass cockpit," to U.S. Rep. Dave Weldon. The congressman is on the House Science Committee and vice chairman of the Space and Aeronautics Subcommittee. He was in Palmdale, Calif., when Atlantis underwent the modification and he wanted to see the final product. The full-color, flat-panel MEDS upgrade improves crew/orbiter interaction with easy-to-read, graphic portrayals of key flight indicators like attitude display and mach speed. The installation makes Atlantis the most modern orbiter in the fleet and equals the systems on current commercial jet airliners and military aircraft. Atlantis is scheduled to fly on mission STS-101 in early December
