EDWARDS AIR FORCE BASE Edwards Air Force Base, U.S. military installation, 301,000 acres (121,805 hectares), S Calif., NE of Lancaster; est. 1933. It is one of the largest air force bases in the United States and has the world's longest runway. - Edwards Air Force Base officials are positioning the base for future tests of experimental aircraft and spaceships by conducting an environmental review on the impact of approach and landing operations for such craft.
In a draft environmental assessment, Edwards is called a cost-effective site for such operations because of its long history with X-series planes and space shuttle space shuttle, reusable U.S. space vehicle. Developed by the National Aeronautics and Space Administration (NASA), it consists of a winged orbiter, two solid-rocket boosters, and an external tank. landings.
Authors of the draft report concluded there would be no significant impacts to the environment because flight tests of such a vehicle would represent less than 1 percent of the normal flight activity already taking place at Edwards.
``Edwards AFB AFB
AFB Acid-fast bacillus, also 1. Aflatoxin B 2. Aorto-femoral bypass has historically been selected as a primary testing site for new aircraft and space vehicles because of the remote surroundings and viable landing options,'' the report says. ``The hard surface runways and the hard flat surface of the Rosamond and Rogers dry lake beds have proven ideal for parachute/parasail landings and normal aircraft landings.
``Edwards Air Force Base is a cost-effective location for re-entry RE-ENTRY, estates. The resuming or retaking possession of land which the party lately had.
2. Ground rent deeds and leases frequently contain a clause authorizing the landlord to reenter on the non-payment of rent, or the breach of some covenant, when the landings because of the facilities in place, its remote location and previous success in its use for space shuttle and other unmanned vehicle flights and landings,'' report authors wrote.
The environmental report is being compiled in a joint effort by the Air Force and the National Aeronautics and Space Administration National Aeronautics and Space Administration (NASA), civilian agency of the U.S. federal government with the mission of conducting research and developing operational programs in the areas of space exploration, artificial satellites (see satellite, artificial), , which operates the Dryden Flight Research Center The Dryden Flight Research Center (DFRC), located inside Edwards Air Force Base, is an aeronautical research center operated by NASA. On March 26, 1976 it was named in honor of the late Hugh L. at the base.
``The selection of Edwards AFB as the preferred landing site for the re- entry corridor is based on extensive capabilities that exist at the site and the fact that flight corridors would most likely be over sparsely populated areas from the West Coast to the inland Edwards AFB landing site.''
The environmental assessment is not being conducted for any specific aircraft but rather for a ``generic'' one envisioned in the future.
The environmental assessment would support efforts to expedite Federal Aviation Administration Federal Aviation Administration (FAA), component of the U.S. Department of Transportation that sets standards for the air-worthiness of all civilian aircraft, inspects and licenses them, and regulates civilian and military air traffic through its air traffic control licensing for craft returning from the International Space Station, including unmanned tests of a space station ``lifeboat'' or recovery vehicle from a commercial space venture.
``This is a document getting (the Department of Defense) ready to handle any future missions that might come up,'' said Phil Brady, a former Edwards official who is now a consultant on aerospace issues for the city of Lancaster The City of Lancaster (2002 population: 133,914) is a local government district with city status in Lancashire, England. Its main town is Lancaster, from which it obtained its city status. Other towns in the district include Morecambe, Heysham, Slyne, and Carnforth. . ``They are getting ready for whatever comes.''
The study envisions a wingless generic vehicle 30 feet long, 15 1/2 feet wide and 25,000 pounds. In comparison, the space shuttles The term Space Shuttles refers to partly or fully reusable launch vehicles for regularly placing payloads into low earth orbit.

Lifting body shapes are being considered in studies for a possible spacecraft that would be used to send astronauts to the International Space Station and could be used for a space station lifeboat.
Researchers for the report are looking at two main corridors. The first is a 140-mile-wide western corridor in which the spacecraft would come in over the California coast between Monterey and Santa Barbara Santa Barbara (săn'tə bär`brə, –bərə), city (1990 pop. 85,571), seat of Santa Barbara co., S Calif., on the Pacific Ocean; inc. 1850. . The spacecraft would cross the coast at an altitude of 108,000 feet.
The second corridor is 240 miles wide as it crosses southwestern Oregon and extends south through California over the Sierra Nevada. The unmanned spacecraft would cross the Oregon coastline at approximately 160,000 feet above sea level.
A number of other corridors were considered but rejected because they posed a risk of high casualties on the ground in the event of a crash.
The required runway length for the generic craft is between 8,000 and 12,000 feet. The primary runway at Edwards, Runway 22, is 15,000 feet long and 300 feet wide. No new or specialized equipment would be required to support the unmanned vehicle's approach and landing, the report says.
Approximately 30 minutes before touchdown, the unmanned spacecraft would begin entering the atmosphere at an altitude of about 400,000 feet. At approximately 45,000 feet and within five nautical miles of Edwards, the spacecraft would begin to maneuver for the final landing approach at the desired altitude and speed.
The final approach and landing would be accomplished through a shuttle-type landing pattern on either Runway 22 or on Rogers Dry Lake.
``The open terrain and lack of vertical features has contributed to the safe recovery of many test vehicles, something that would not have been possible in a less remote area,'' the report says.
