The NASA Wallops Flight Facility Range

Wallops Flight Facility (IATA: WAL, ICAO: KWAL), located on the Eastern Shore of Virginia, is operated by the National Aeronautics and Space Administration’s (NASA) Goddard Space Flight Center primarily as a rocket launch site to support science and exploration missions for NASA and other federal agencies. WFF includes an extensively instrumented range to support launches of more than a dozen types of sounding rockets, small expendable suborbital and orbital rockets, high altitude balloon flights carrying scientific instruments for atmospheric and astronomical research and—using its Research Airport—flight tests of aeronautical research aircraft including unmanned aerial vehicles. The WFF range supports science missions for the National Oceanic and Atmospheric Administration (NOAA) and occasionally for foreign governments and commercial organizations. It also supports development tests and exercises involving U.S. Navy aircraft and ship-based electronics and weapon systems in the Virginia Capes operating area near the entrance to the Chesapeake Bay.

In addition to its fixed-location instrumentation assets, the WFF range includes mobile radars, telemetry receivers, and command transmitters that can be deployed by aircraft to locations around the world to establish a temporary range where no other instrumentation exists to ensure safety and collect data to enable and support suborbital rocket launches from remote sites. The WFF mobile range assets have been used to support rocket launches from locations in the Arctic and Antarctic regions, South America, Africa, Europe, Australia, and even at sea.

More than 1,000 full-time Civil Service employees work for NASA at Wallops Flight Facility each day, along with more than 300 Navy personnel and almost 100 employees of NOAA.

The Wallops Visitor Center has a variety of hands-on exhibits and it hosts weekly educational activities and programs designed to enable children to explore and learn about the technologies designed and used by NASA researchers and scientists. In addition, one Saturday each month, NASA invites model rocketry enthusiasts to bring their own rockets and launch them from the WFF rocket launch site. NASA personnel also participate, launching models of various rockets and explaining the spacecraft they carry in real life. If you are interested in participating in one of these programs, or would like to find out more about these activities, please contact the NASA Wallops Flight Facility Public Affairs Office at 757-824-1579.

[edit] History

Early research rockets at Wallops Island.

In 1945, NASA's predecessor agency, the National Advisory Committee for Aeronautics (NACA), established a rocket launch site on Wallops Island under the direction of the Langley Research Center. This site was designated the Pilotless Aircraft Research Station and conducted high-speed aerodynamic research to supplement wind tunnel and laboratory investigations into the problems of flight. In 1958, Congress established the National Aeronautics and Space Administration (NASA), which absorbed Langley Research Center and other NACA field centers and research facilities. At that time, the Pilotless Aircraft Research Station became a separate facility - Wallops Station - operating directly under NASA Headquarters in Washington, D.C. In 1959, NASA acquired the former Chincoteague Naval Air Station, and engineering and administrative activities were moved to this location. In 1974, the Wallops Station was named Wallops Flight Center. The name was changed to Wallops Flight Facility in 1981, when it became part of Goddard Space Flight Center, Greenbelt, Maryland.

In the early years, research at Wallops was concentrated on obtaining aerodynamic data at transonic and low supersonic speeds. Between 1959 and 1961, Project Mercury capsules were tested at Wallops in support of NASA's manned space flight program before the astronauts were launched from Cape Canaveral, Florida. Some of these tests using the Little Joe Booster rocket were designed to flight-qualify components of the Mercury spacecraft, including the escape and recovery systems and some of the life support systems. Two rhesus monkeys, Sam and Miss Sam, were sent aloft acting as pioneers for the astronauts; both were recovered safely. Since 1945, the Wallops Test Range has launched more than 14,000 research vehicles in the quest for information on the flight characteristics of airplanes, launch vehicles, and spacecraft, and to increase the knowledge of the Earth's upper atmosphere and the near space environment. The launch vehicles vary in size and power from the small Super Loki meteorological rockets to orbital class vehicles.

Wallops Flight Facility continues to be a small, fast response, matrix organization that can accomplish rocket and balloon projects, spacecraft orbital tracking, airborne science support, and aeronautical research.

[edit] Location

The WFF Main Base is located on the Eastern Shore of Virginia, on the Delmarva Peninsula 5 miles west of Chincoteague, Virginia, approximately 90 miles north of Norfolk, Virginia, and 40 miles southeast of Salisbury, Maryland. WFF consists of three separate parcels of real property totaling 6,200 acres (25 km²): the Main Base, the Mainland, and the Wallops Island Launch Site. The Mainland and the Wallops Island Launch Site are approximately 7 miles southeast of the Main Base.

[edit] Facilities Overview

WFF has a wide variety of facilities to support its operations, providing a combination of low cost access to space and the ability to respond quickly to the demand for range services. The NASA Wallops Research Range is like a “Wind Tunnel in the Sky”, providing benefits to the scientific and experimental launch vehicle communities, and offering test support to enable development and testing of space exploration systems and technologies.

Critical to these activities are controlled airspace, Federal Aviation Administration (FAA) certified runways, an experimental UAV runway, Crash, Fire & Rescue Services, and FAA qualified Air Traffic Controllers. The controlled airspace includes the following restricted areas:

The WFF Airport Control Zone to 2,500 feet within a 5-statute mile radius of the airport
Restricted Area R-6604 connecting WFF airspace and offshore warning areas.

Wallops Research Airport and Main Base.

WFF has facilities for the receipt, inspection, assembly, checkout, and storage of rocket motors and other hazardous pyrotechnic devices. The Wallops Island Launch Site includes six launch pads, three blockhouses for launch control, and assembly buildings to support the preparation and launching of suborbital and orbital launch vehicles.

The Wallops Research Range includes ground-based and mobile systems, and a range control center. Its radar facilities and systems are used for tracking and surveillance. Telemetry facilities include a variety of antennas, receivers, and display instrumentation systems. Command uplink and optical tracking facilities are included as part of the range. The Wallops Research Range also provides premier digital photographic and video services including operation of numerous still cameras, high speed and video systems for Range Safety support, surveillance, and post-launch analysis (e.g., failure analysis), project documentation (e.g., fabrication and test), administrative documentation, and archiving for environmental studies. In addition, WFF has a variety of communications systems and facilities to route voice, video, and data in support of launch processing, flight and test operations.

The Wallops mobile range instrumentation includes telemetry, radar, command and power systems. These assets are used as needed to supplement instrumentation at existing ranges, or to establish a temporary range to ensure safety and collect data to support the rocket customers in a remote location where no other range instrumentation exists. This complement of transportable systems can be deployed to provide complete range capabilities at remote locations around the world.

The NASA Wallops Mobile Range instrumentation has been deployed to support launch events in dozens of locations around the world.

While Wallops Island, Virginia is the prime location for range services major sounding rocket campaigns have been supported at Poker Flat, Alaska, Andoya, Norway and Kwajalein Island, Marshall Islands. The Balloon Program and meteorological research missions have required range services to travel to some of the most remote locations on the earth. The Wallops Mobile Instrumentation is unique in that it integrates seamlessly into NASA and Department of Defense (DoD) networks, and can be used to supplement established ranges in support of rocket launches. The WFF Research Airport is located on the Main Base. There are three runway(from 4,810 to 8,750 feet long), two taxiways, three ramps, and one hazardous cargo loading area in active service. Two ramps adjoin the two active hangars, and a third ramp adjoins the Crash Fire and Rescue building. The primary research runway has a test section with a variety of surface textures and materials for runway research projects.

Weather measurements and predictions are critical to all Research Airport operations, rocket and balloon launches, and in safely conducting hazardous operations on the ground. NASA Wallops meteorological services provide measurements of upper atmospheric and magnetic phenomena to augment and enable collection of scientific data by sensors aboard flight vehicles. The SPANDAR S-band Doppler Radar system at Wallops is the most capable research radar in the world, capable of automatic unambiguous tracking of targets up to 60,000 kilometers away. It can detect a single 3-millimeter raindrop at a range of 10 kilometers and cloud water content as little as 1 gram per cubic meter. SPANDAR’s sensitivity with its 60-foot dish antenna can detect small changes in the refractive index of air caused by sea breeze fronts, gust fronts, and various forms of clear air turbulence. SPANDAR and the other atmospheric instrumentation at Wallops provide the most instrumented column of air between earth and space.

[edit] Range Technology Development

Envisioned Future Range Architecture.

Low-Cost TDRSS Transceiver (LCT2) prototype hardware developed by NASA WFF and schematic comparing NASA WFF’s Autonomous Flight Safety System (AFSS) to traditional (manual) flight safety system in use today.

The Wallops Research Range is well designed to lead the development of promising range technologies for NASA, DoD and FAA. Current, proven range systems can be operated in parallel while new technologies are being developed and tested, without adding risk to a large expensive payload and without causing safety issues.

Since 2001, engineers at NASA Wallops Flight Facility have been working to address advances in range technology that can provide the best leverage to improve the cost and responsiveness of launch and flight test activities, by developing new systems and approaches that can be implemented within the constraints of available funding and program schedules. Specifically, NASA Wallops has been leading two range technology development projects the Autonomous Flight Safety System (AFSS) and the Low Cost TDRSS Transceiver (LCT2).

The AFSS project seeks to develop an autonomous on-board system that can augment or replace the function of the traditional ground-commanded Range Safety flight termination system. The AFSS will use redundant on-board navigation sensors and flight processors to monitor the progress of the expendable launch vehicle with respect to multiple flight termination criteria (based on safety and risk analysis) and if necessary, generate signals that can be used to initiate pyrotechnic devices to terminate the flight.

The goal of the LCT2 effort is to produce a transceiver that will significantly lower the flight hardware costs required to communicate through NASA's Tracking and Data Relay Satellite System (TDRSS) and will meet the suborbital and orbital launch vehicle needs for telemetry and command relay over the horizon from the launch site. Its design and development are being pursued as part of the Space Based Range Demonstration and Certification (SBRDC) program (formerly called Space Based Telemetry and Range Safety (STARS)) in cooperation with NASA Kennedy Space Center.
