Ames Research Center
The Ames Research Center (ARC), also known as NASA Ames, is a major NASA research center at Moffett Federal Airfield in California's Silicon Valley. It was founded in 1939[1] as the second National Advisory Committee for Aeronautics (NACA) laboratory. That agency was dissolved and its assets and personnel transferred to the newly created National Aeronautics and Space Administration (NASA) on October 1, 1958. NASA Ames is named in honor of Joseph Sweetman Ames, a physicist and one of the founding members of NACA. At last estimate NASA Ames had over US$3 billion in capital equipment, 2,300 research personnel and a US$860 million annual budget.

- Eugene Tu, director
Ames was founded to conduct wind-tunnel research on the aerodynamics of propeller-driven aircraft; however, its role has expanded to encompass spaceflight and information technology. Ames plays a role in many NASA missions. It provides leadership in astrobiology; small satellites; robotic lunar exploration; the search for habitable planets; supercomputing; intelligent/adaptive systems; advanced thermal protection; planetary science; and airborne astronomy. Ames also develops tools for a safer, more efficient national airspace. The center's current director is Eugene Tu.[2]
The site was mission center for several key missions (Kepler, the Stratospheric Observatory for Infrared Astronomy (SOFIA), Interface Region Imaging Spectrograph) and a major contributor to the "new exploration focus"[3] as a participant in the Orion crew exploration vehicle.
Air traffic control automation research[edit]
The Aviation Systems Division conducts research and development in two primary areas: air traffic management, and high-fidelity flight simulation. For air traffic management, researchers are creating and testing concepts to allow for up to three times today's level of aircraft in the national airspace. Automation and its attendant safety consequences are key foundations of the concept development. Historically, the division has developed products that have been implemented for the flying public, such as the Traffic Management Adviser, which is being deployed nationwide. For high-fidelity flight simulation, the division operates the world's largest flight simulator (the Vertical Motion Simulator), a Level-D 747-400 simulator, and a panoramic air traffic control tower simulator. These simulators have been used for a variety of purposes including continued training for Space Shuttle pilots, development of future spacecraft handling qualities, helicopter control system testing, Joint Strike Fighter evaluations, and accident investigations. Personnel in the division have a variety of technical backgrounds, including guidance and control, flight mechanics, flight simulation, and computer science. Customers outside NASA have included the FAA, DOD, DHS, DOT, NTSB, Lockheed Martin, and Boeing.
The center's flight simulation and guidance laboratory was listed on the National Register of Historic Places in 2017.
Image processing[edit]
NASA Ames was one of the first locations to conduct research on image processing of satellite-platform aerial photography. Some of the pioneering techniques of contrast enhancement using Fourier analysis were developed at Ames in conjunction with researchers at ESL Inc.
Arc Jet Complex[edit]
The Ames Arc Jet Complex is an advanced thermophysics facility where sustained hypersonic- and hyperthermal testing of vehicular thermoprotective systems takes place under a variety of simulated flight- and re-entry conditions. Of its seven available test bays, four currently contain Arc Jet units of differing configurations, serviced by common facility support equipment. These are the Aerodynamic Heating Facility (AHF), the Turbulent Flow Duct (TFD), the Panel Test Facility (PTF), and the Interaction Heating Facility (IHF). The support equipment includes two D.C. power supplies, a steam ejector-driven vacuum system, a water-cooling system, high-pressure gas systems, data acquisition system, and other auxiliary systems.
The magnitude and capacity of these systems makes the Ames Arc Jet Complex unique. The largest power supply can deliver 75 megawatts (MW) for a 30-minute duration or 150 MW for a 15-second duration. This power capacity, in combination with a high-volume 5-stage steam ejector vacuum-pumping system, enables facility operations to match high-altitude atmospheric flight conditions with samples of relatively large size. The Thermo-Physics Facilities Branch operates four arc jet facilities. The Interaction Heating Facility (IHF), with an available power of over 60-MW, is one of the highest-power arc jets available. It is a very flexible facility, capable of long run times of up to one hour, and able to test large samples in both a stagnation and flat plate configuration. The Panel Test Facility (PTF) uses a unique semielliptic nozzle for testing panel sections. Powered by a 20-MW arc heater, the PTF can perform tests on samples for up to 20 minutes. The Turbulent Flow Duct provides supersonic, turbulent high temperature air flows over flat surfaces. The TFD is powered by a 20-MW Hüls arc heater and can test samples 203 by 508 millimeters (8.0 by 20.0 in) in size. The Aerodynamic Heating Facility (AHF) has similar characteristics to the IHF arc heater, offering a wide range of operating conditions, sample sizes and extended test times. A cold-air-mixing plenum allows for simulations of ascent or high-speed flight conditions. Catalycity studies using air or nitrogen can be performed in this flexible rig. A 5-arm model support system allows the user to maximize testing efficiency. The AHF can be configured with either a Hüls or segmented arc heater, up to 20-MW. 1 MW is enough power to supply 750 homes.
The Arc Jet Complex was listed on the National Register in 2017.
Range complex[edit]
Ames Vertical Gun Range[edit]
The Ames Vertical Gun Range (AVGR) was designed to conduct scientific studies of lunar impact processes in support of the Apollo missions. In 1979, it was established as a National Facility, funded through the Planetary Geology and Geophysics Program. In 1995, increased scientific needs across various disciplines resulted in joint core funding by three different science programs at NASA Headquarters (Planetary Geology and Geophysics, Exobiology, and Solar System Origins). In addition, the AVGR provides programmatic support for various proposed and ongoing planetary missions (e.g. Stardust, Deep Impact).
Using its 0.30 cal light-gas gun and powder gun, the AVGR can launch projectiles to velocities ranging from 500 to 7,000 m/s (1,600 to 23,000 ft/s; 1,100 to 15,700 mph). By varying the gun's angle of elevation with respect to the target vacuum chamber, impact angles from 0° to 90° relative to the gravitational vector are possible. This unique feature is extremely important in the study of crater formation processes.
The target chamber is approximately 2.5 meters (8 ft 2 in) in diameter and height and can accommodate a wide variety of targets and mounting fixtures. It can maintain vacuum levels below 0.03 torrs (4.0 Pa), or can be back filled with various gases to simulate different planetary atmospheres. Impact events are typically recorded with high-speed video/film, or Particle Image Velocimetry (PIV).
Hypervelocity Free-Flight Range[edit]
The Hypervelocity Free-Flight (HFF) Range currently comprises two active facilities: the Aerodynamic Facility (HFFAF) and the Gun Development Facility (HFFGDF). The HFFAF is a combined Ballistic Range and Shock-tube Driven Wind Tunnel. Its primary purpose is to examine the aerodynamic characteristics and flow-field structural details of free-flying aeroballistic models.
The HFFAF has a test section equipped with 16 shadowgraph-imaging stations. Each station can be used to capture an orthogonal pair of images of a hypervelocity model in flight. These images, combined with the recorded flight time history, can be used to obtain critical aerodynamic parameters such as lift, drag, static and dynamic stability, flow characteristics, and pitching moment coefficients. For very high Mach number (M > 25) simulations, models can be launched into a counter-flowing gas stream generated by the shock tube. The facility can also be configured for hypervelocity impact testing and has an aerothermodynamic capability as well. The HFFAF is currently configured to operate the 1.5 inches (38 mm) light-gas gun in support of continuing thermal imaging and transition research for NASA's hypersonics program.
The HFFGDF is used for gun performance enhancement studies, and occasional impact testing. The Facility uses the same arsenal of light-gas and powder guns as the HFFAF to accelerate particles that range in size from 3.2 to 25.4 millimeters (0.13 to 1.00 in) diameter to velocities ranging from 0.5 to 8.5 km/s (1,100 to 19,000 mph). Most of the research effort to date has centered on Earth atmosphere entry configurations (Mercury, Gemini, Apollo, and Shuttle), planetary entry designs (Viking, Pioneer Venus, Galileo and MSL), and aerobraking (AFE) configurations. The facility has also been used for scramjet propulsion studies (National Aerospace Plane (NASP)) and meteoroid/orbital debris impact studies (Space Station and RLV). In 2004, the facility was utilized for foam-debris dynamics testing in support of the Return To Flight effort. As of March 2007, the GDF has been reconfigured to operate a cold gas gun for subsonic CEV capsule aerodynamics.
Electric Arc Shock Tube[edit]
The Electric Arc Shock Tube (EAST) Facility is used to investigate the effects of radiation and ionization that occur during very high velocity atmospheric entries. In addition, the EAST can also provide air-blast simulations requiring the strongest possible shock generation in air at an initial pressure loading of 1 standard atmosphere (100 kPa) or greater. The facility has three separate driver configurations, to meet a range of test requirements: the driver can be connected to a diaphragm station of either a 102 millimeters (4.0 in) or a 610 millimeters (24 in) shock tube, and the high-pressure 102 millimeters (4.0 in) shock tube can also drive a 762 millimeters (30.0 in) shock tunnel. Energy for the drivers is supplied by a 1.25-MJ-capacitor storage system.
United States Geological Survey (USGS)[edit]
In September 2016, the United States Geological Survey (USGS) announced plans to relocate its West Coast science center from nearby Menlo Park to the Ames Research Center at Moffett Field. The relocation is expected to take five years and will begin in 2017 with 175 of the USGS employees moving to Moffett. The relocation is designed to save money on the $7.5 million annual rent the USGS pays for its Menlo Park campus. The land in Menlo Park is owned by the General Services Administration, which is required by federal law to charge market-rate rent.[17]
Education[edit]
NASA Ames Visitor Center[edit]
The NASA Experience exhibit at the Chabot Space and Science Center serves as the visitor center for NASA's Ames Research Center. The NASA Experience provides a dynamic and interactive space for the public to learn about local contributions to space exploration across the years. From models of spacecraft and genuine spacesuits from as early as the Mercury and Gemini missions to artifacts related to NASA's upcoming Artemis missions, the NASA Ames Visitor Center gives visitors access to over 80 years of Ames history and a look into current and future projects. Ames' expertise in wind tunnel testing, rover design and testing, space robotics, supercomputing, and more is on display. The exhibit was opened on November 12, 2021.
Living and working at Ames[edit]
An official NASA ID is required to enter Ames.
There are myriad activities both inside the research center and around the base for full-time workers and interns alike. Portions of a fitness trail remain inside the base (also called a Parcourse trail), Sections of it are now inaccessible due to changes in base layout since it was installed.
