Biographical / Historical:
In 2000, the Space Shuttle Endeavour carried the Shuttle Radar Topography Mission (SRTM) payload into orbit. Shuttle astronauts used the payload, manufactured by the AEC-Able Engineering Co., to map in high detail and three dimensions more than 70 percent of the Earth's surface--the most complete and accurate rendering of the planet's land masses ever attempted. To acquire this data, the SRTM used a novel hardware system that featured a main antenna located in the Shuttle payload bay, a folding mast (in the mast canister) that extended 60 meters from the Shuttle, and then another antenna system that was positioned at the end of the mast (the outboard structure). It was this dual antenna system — the largest rigid structure then flown in space — that produced, through interferometry (a technique for combining the information obtained from the two, separate antennas), a three-dimensional mapping of the Earth. The mission was a joint undertaking of NASA's Jet Propulsion Laboratory (JPL) and the Department of Defense's National Imagery and Mapping Agency. The military will use the highest resolution data from SRTM for terrain navigation for planes and cruise missiles. A lower resolution data set will be made available to civilian scientists and other users.

This collection consists of a scrapbook containing 44 black and white photographs of various sizes as well as four typewritten pages describing the photographs and the flight tests they depict. Photographs are divided into five "exhibits." Exhibit I is noted to be the solid propellant jet unit. Exhibit II depicts flight tests conducted from April 7 to 24, 1942 at the US Army Air Forces Bombing & Gunnery Range, Muroc Dry Lake, California using a Douglas A-20A, of experimental liquid propellant jet units developed by the Air Corps Jet Propulsion Research Project at the California Institute of Technology. Liquid propellant jet units shown in this section are the experimental form of units later produced by Aerojet Engineering Corporation for the Army Air Forces. Exhibit III depicts flight tests conducted from January 7 to 8, 1943 at the US Army Air Forces Bombing & Gunnery Range, Muroc Dry Lake, California using a Douglas A-20B of liquid propellant jet units, Model AL-1000, designed by the Aerojet Engineering Corporation. Exhibit IV contains photographs of jet propulsion units that were in production at the Aerojet Engineering Corporation at the time the scrapbook was produced. Exhibit V contains photographs of selected Aerojet Engineering Corporation plant facilities.
Biographical / Historical:
In April 1942, the US Army Air Force was conducting flight testing of experimental liquid propellant units developed by the Air Corps Jet Propulsion Research Project at the California Institute of Technology to determine their effects on reduction of takeoff run, stability and control, high speed performance, blast effects, and reliability. The units were found to reduce takeoff distance by approximately one-third and increase maximum speed by approximately 40 miles per hour. However, improvements were recommended in terms of jet installation. In January 1943, flight tests were conducted by the US Army Air Force on Model AL-1000 liquid propellant jet units developed by Aerojet Engineering Corporation based on the April 1942 testing. The Aerojet units successfully reduced takeoff distance and increased flight velocity, as well as allowing for quick and easy servicing and or unit replacement. Aerojet Engineering Corporation began producing these different models of these units for the US Army Air Force subsequent to this testing.
