This photo shows a head-on view of NASA's SR-71B, used for pilot proficiency and training, on the ramp at the Air Force's Plant 42 in Palmdale, California, shortly before delivery to the Ames-Dryden Flight Research Facility (later, Dryden Flight Research Center) at Edwards, California. NASA operated two of these unique aircraft, an SR-71A, for high-speed, high altitude research, and this SR- 71B pilot trainer for most of the decade of the 1990s. The "B" model is special because of its raised rear cockpit, which provided a second pilot position so a trainer and an experienced pilot could both see what was going on during flights. The SR-71 was designed and built by the Lockheed Skunk Works, now the Lockheed Martin Skunk Works. Studies have shown that less than 20 percent of the total thrust used to fly at Mach 3 is produced by the basic engine itself. The balance of the total thrust is produced by the unique design of the engine inlet and "moveable spike" system at the front of the engine nacelles, and by the ejector nozzles at the exhaust which burn air compressed in the engine bypass system. Data from the SR-71 high speed research program will be used to aid designers of future supersonic/hypersonic aircraft and propulsion systems, including a high speed civil transport.

The scant water available in this area either is absorbed in the sands and gravel of the watercourse or quickly evaporates. Most water flows beneath the surface, then, giving support to plant root systems and sustaining green vegetation along the watercourses.

In this photograph, astronaut Roberta Bondar conducts a life science experiment by using the Biorack Glovebox (GBX) during the International Microgravity Laboratory-1 (IML-1) mission. The Biorack was a large multipurpose facility designed for studying the effects of microgravity and cosmic radiation on numerous small life forms such as cells, tissues, small organisms, and plants. Located at the Biorack, the GBX was an enclosed environment that protected samples from contamination and prevented liquid from escaping. Crewmembers handled the specimens with their hands inside gloves that extended into the sealed work area. A microscope and video camera mounted on the GBX door were used to observe and document experiments. Managed by the Marshall Space Flight Center, the IML-1 mission was the first in a series of Shuttle flights dedicated to fundamental materials and life sciences research and was launched aboard the Shuttle Orbiter Discovery (STS-42) on January 22, 1992.
