A test version of the Orion spacecraft is pulled back like a pendulum and released, taking a dive into the 20-foot-deep Hydro Impact Basin at NASA’s Langley Research Center in Hampton, Virginia.
Crash-test dummies wearing modified Advanced Crew Escape Suits are securely seated inside the capsule to help engineers understand how splashdown in the ocean during return from a deep-space mission could impact the crew and seats. Each test in the water-impact series simulates different scenarios for Orion’s parachute-assisted landings, wind conditions, velocities and wave heights the spacecraft and crew may experience when landing in the ocean upon return missions in support of the journey to Mars.

A mock-up of NASA's Orion spacecraft recently took an east coast journey from the agency's Kennedy Space Center in Florida to Langley Research Center in Hampton, Va., in preparation for future testing at Langley's Landing and Impact Research Facility. Testing will give engineers insight into how the capsule performs under a variety of ocean and landing conditions. This fall, the Orion spacecraft will fly on its first uncrewed mission, known as Exploration Flight Test-1, where it will travel 3,600 miles above Earth before reentering the atmosphere at a speed of approximately 20,000 mph (32,187 kph) and temperatures of close to 4,000 degrees Fahrenheit (2,200 degrees Celsius) for a splashdown in the Pacific Ocean.

What is now the Landing Impact and Research Facility at NASA's Langley Research Center in Hampton, Va., was built in 1965 to test the lunar landing module, which simulated touchdown procedures for the Apollo moon missions. At 240 feet high and 400 feet long, it looks like a giant steel erector set.
It is now used to conduct crash testing of full scale aircraft under controlled conditions and splash testing of space capsule mock ups.

Gust Tunnel
History
Langley Building 1218 was constructed in August 1945 for the purpose of conducting experiments on gust loads using free-flight models catapulted through a vertical airstream. When the gust research activity was terminated in the mid-1950s, the building occupancy was divided between research office space (designated Building 1218) and an anechoic test facility (designated Building 1218-A). The anechoic test capability was retained through 2009, while the office areas were subsequently converted to an Executive Conference Center.
Gust Tunnel
The aircraft design process devotes considerable time to ensure that the airframe structure will be the lightest and most acceptable approach to meeting requirements based on in-flight and ground-induced structural loads. One traditional challenge has been the development and validation of technical methods to predict air loads experienced during flight in gusts and turbulence. This capability is extremely important, not only from a safety-of-flight perspective, but also to prevent an over design of aircraft structures which would result in unnecessarily large weight penalties. Early research in the 1920s and 1930s at the NACA Langley laboratory included theoretical studies of loads generated in specific gust fields, but flight data to substantiate the predictions were extremely difficult to obtain at that time. In order to experimentally investigate gust loads under controlled conditions, the NACA designed and constructed a pilot gust tunnel in 1937 within an area of the Langley Full-Scale Tunnel building (Building 643) outside the tunnel flow circuit. This pilot gust-tunnel facility operated in the NACA East Area for almost a decade.
The pilot gust-tunnel testing technique consisted of launching dynamically scaled, free-flight airplane models through gusts of known shapes and intensities. During the flight measurements were made of the accelerations and reactions of the models due to the gusts. The test facility consisted of a gust generator, a catapult for launching the models, and two screens used to decelerate and catch the airplane model at the end of the flight...

30 X 60 Full Scale Tunnel
History
Commonly referred to as the Full Scale Tunnel, Building 643 in the NASA East Area has been the site of four historically significant activities since its construction in 1930. These activities have spanned from the era of biplanes to NASA space programs. The following provides information on research activities in some of the most important programs conducted in Building 643.
Full Scale Tunnel was demolished in 2011 after many years of continuous use. (See Tribute) Artifacts from this National Historic Landmark were salvaged for displays, including the Smithsonian's Milestones of Flight exhibit. See Artifacts for a listing of salvaged items.
Full-Scale Wind Tunnel
After the Variable Density Tunnel (VDT) of the National Advisory Committee for Aeronautics (NACA) was put into operation in the 1920s, it was recognized as a breakthrough accomplishment in wind-tunnel testing technology. By using higher than atmospheric pressure in its airstream, the VDT provided aerodynamic conditions more representative of those experienced in flight. However, the relatively small size of its test section required the use of relatively small aircraft models and severely limited testing of full-scale airplane components. Powered models could not be accommodated, and the aerodynamic effects of real aircraft construction such as rivets, fabric, and other component details were difficult or impossible to simulate. Of even more concern, however, was the recognition that significant aerodynamic turbulence was present in the tunnel air flow due to the geometrical shape of the VDT. As the concern over results from the VDT began to grow, several research leaders at Langley began to advocate for a new large wind tunnel capable of conducting tests of full-scale aircraft at that time.
The NACA authorized the construction of the Full-Scale Tunnel (FST) at Langley in February 1929 and design work started immediately. Smith J. DeFrance led the design team, which also included Abraham Silverstein, Clinton H. Dearborn, and Harry J. Goett. Significantly, three of these NACA researchers later became Directors of NACA or NASA field centers...

http://en.wikipedia.org/wiki/Wind
Wind is the flow of gases on a large scale. On Earth, wind consists of the bulk movement of air. In outer space, solar wind is the movement of gases or charged particles from the sun through space, while planetary wind is the outgassing of light chemical elements from a planet's atmosphere into space. Winds are commonly classified by their spatial scale, their speed, the types of forces that cause them, the regions in which they occur, and their effect. The strongest observed winds on a planet in our solar system occur on Neptune and Saturn.
In meteorology, winds are often referred to according to their strength, and the direction from which the wind is blowing. Short bursts of high speed wind are termed gusts. Strong winds of intermediate duration (around one minute) are termed squalls. Long-duration winds have various names associated with their average strength, such as breeze, gale, storm, hurricane, and typhoon. Wind occurs on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few hours, to global winds resulting from the difference in absorption of solar energy between the climate zones on Earth. The two main causes of large-scale atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet (Coriolis effect). Within the tropics, thermal low circulations over terrain and high plateaus can drive monsoon circulations. In coastal areas the sea breeze/land breeze cycle can define local winds; in areas that have variable terrain, mountain and valley breezes can dominate local winds.
In human civilization, wind has inspired mythology, influenced the events of history, expanded the range of transport and warfare, and provided a power source for mechanical work, electricity and recreation. Wind powers the voyages of sailing ships across Earth's oceans. Hot air balloons use the wind to take short trips, and powered flight uses it to increase lift and reduce fuel consumption. Areas of wind shear caused by various weather phenomena can lead to dangerous situations for aircraft. When winds become strong, trees and man-made structures are damaged or destroyed.
Winds can shape landforms, via a variety of aeolian processes...

8-Foot High Speed Tunnel
As interest in the field of high-speed aerodynamics increased in the early 1930s, Langley's existing wind tunnels proved too small and underpowered for effective high-speed aircraft testing. Understanding that a new facility would give U.S. engineers a decided advantage in the aeronautical field, Langley's director of research George W. Lewis authorized the design and construction of a larger high speed wind tunnel in 1933. Construction of the 8-Foot High Speed Tunnel (HST) was funded by the Public Works Administration (PWA) and completed in 1936 at a cost of $266,000...

Stapp also participated in wind-blast experiments, in which he flew in jet aircraft at high speeds to determine whether or not it was safe for a pilot to remain with his aircraft if the canopy should accidentally blow off. Stapp stayed with his aircraft at a speed of 570 mph (917 km/h), with the canopy removed, and suffered no injurious effects from the wind blasts. Among these experiments was one of the first high-altitude skydives, executed by Stapp himself.

http://en.wikipedia.org/wiki/Aerodynamic_heating
Aerodynamic heating is the heating of a solid body produced by the passage of fluid (such as air) over a body such as a meteor, missile, or airplane. It is a form of forced convection in that the flow field is created by forces beyond those associated with the thermal processes. The heat transfer essentially occurs at the vehicle surface where aerodynamic viscous forces ensures that the flow is at zero speed relative to the body for a very thin layer of molecules at the surface.
When fluid flow slows down its kinetic energy is converted to heat; in high speed flows, tremendous energy is represented by the mean motion of the flow. As the flow is slowed to near zero speed, its temperature increases, the gradient in the speed in a direction normal to the surface allows small scale mass transport effects to dissipate the temperature in the outward direction and thus the temperature at the surface is less than the stagnation temperature; the actual temperature is referred to as the recovery temperature. These viscous dissipative effects to neighboring sub-layers make the boundary layer slow down via a non-isentropic process. Heat then conducts into the surface material from the higher temperature air. The result is an increase in the temperature of the material and a loss of energy from the flow. The forced convection ensures that other material replenishes the gases that have cooled to continue the process.
The stagnation and the recovery temperature of a flow increases with the speed of the flow and are greater at high speeds. The total thermal loading of the structure is a function of both the recovery temperature and the mass flow rate of the flow. Aerodynamic heating is greatest at high speed and in the lower atmosphere where the density is greater. In addition to the convective process described above, there is also radiative heat transfer from the flow to the body and vice versa with the net direction set by the relative temperature of each.
Aerodynamic heating increases with the speed of the vehicle and is continuous from zero speed. It produces much less heating at subsonic speeds but becomes more important at supersonic speeds. At these speeds it can induce temperatures that begin to weaken the materials that compose the object. The heating effects are greatest at leading edges. Aerodynamic heating is dealt with by the use of high temperature alloys for metals, the addition of insulation of the exterior of the vehicle, or the use of ablative material.
Aircraft
Aerodynamic heating is a concern for supersonic and hypersonic aircraft. The Concorde dealt with the increased heat loads at its leading edges by the use of high temperature materials and the design of heat sinks into the aircraft structure at the leading edges. Higher speed aircraft such as the SR-71 deal with the issue by the use of insulating material and material selection on the exterior of the vehicles. Some designs for hypersonic missiles would employ liquid cooling of the leading edges (usually the fuel en route to the engine).
Reentry vehicles
Aerodynamic heating is also a topic of concern in reentry vehicles. The heating induced by the very high speeds of reentry of greater than Mach 20 is sufficient to destroy the structure of the vehicle. The early space capsules such as those on Mercury, Gemini, and Apollo were given blunt shapes to produce a stand-off bow shock. As a result most of the heat is dissipated to surrounding air without transferring through the vehicle structure. Additionally, these vehicles had ablative material that sublimates into a gas at high temperature. The act of sublimation absorbs the thermal energy from the aerodynamic heating and erodes the material away as opposed to heating the capsule. The surface of the heat shield for the Mercury spacecraft had a coating of aluminum with glassfiber in many layers. As the temperature rose to 2,000 °F (1,100 °C) the layers would evaporate and take the heat with it. The spacecraft would become hot but not harmfully so. The Space Shuttle used insulating tiles on its lower surface to absorb and radiate heat while preventing conduction to the aluminum airframe. The compromise of the heat shield during liftoff of Space Shuttle Columbia contributed to its destruction upon reentry...

NASA Langley researchers want to get a better idea about conditions on our nearest planetary neighbor, Venus, so they have come up with HAVOC or a High Altitude Venus Operational Concept – a lighter-than-air rocket ship that would help send two astronauts on a 30-day mission to explore the planet’s atmosphere. Exploration of Venus is a challenge not only because its smog-like sulfuric acid-laced atmosphere, but also its extremely hot surface temperature and extremely high air pressure on the surface.

Langley Research Center
Langley Research Center (LaRC) is the oldest of NASA's field centers, located in Hampton, Virginia, United States. It directly borders Poquoson, Virginia and Langley Field. LaRC focuses primarily on aeronautical research, though the Apollo lunar lander was flight-tested at the facility and a number of high-profile space missions have been planned and designed on-site.
Established in 1917 by the National Advisory Committee for Aeronautics, the Center currently devotes two-thirds of its programs to aeronautics, and the rest to space. LaRC researchers use more than 40 wind tunnels to study improved aircraft and spacecraft safety, performance, and efficiency. Between 1958 and 1963, when NASA started Project Mercury, LaRC served as the main office of the Space Task Group, with the office being transferred to the Manned Spacecraft Center (now the Lyndon B. Johnson Space Center) in Houston in 1962–63.
The current director is David E. Bowles.
History
In 1917, less than three years after it was created, the NACA established Langley Memorial Aeronautical Laboratory on Langley Field. Both Langley Field and the Langley Laboratory are named for aviation pioneer Samuel Pierpont Langley. The Aviation Section, U.S. Signal Corps had established a base there earlier that same year. The first research facilities were in place and aeronautical research was started by 1920. Initially the laboratory included four researchers and 11 technicians.

The heating induced by the very high speeds of reentry of greater than Mach 20 is sufficient to destroy the structure of the vehicle. The early space capsules such as those on Mercury, Gemini, and Apollo were given blunt shapes to produce a stand-off bow shock. As a result most of the heat is dissipated to surrounding air without transferring through the vehicle structure. Additionally, these vehicles had ablative material that sublimates into a gas at high temperature. The act of sublimation absorbs the thermal energy from the aerodynamic heating and erodes the material away as opposed to heating the capsule. The surface of the heat shield for the Mercury spacecraft had a coating of aluminum with glassfiber in many layers. As the temperature rose to 2,000 °F (1,100 °C) the layers would evaporate and take the heat with it. The spacecraft would become hot but not harmfully so. The Space Shuttle used insulating tiles on its lower surface to absorb and radiate heat while preventing conduction to the aluminum airframe. The compromise of the heat shield during liftoff of Space Shuttle Columbia contributed to its destruction upon reentry... Langley Physical Research Lab http://crgis.ndc.nasa.gov/historic/1229 -
3:35A way to explore Venus
A way to explore VenusA way to explore Venus
NASA Langley researchers want to get a better idea about conditions on our nearest planetary neighbor, Venus, so they have come up with HAVOC or a High Altitude Venus Operational Concept – a lighter-than-air rocket ship that would help send two astronauts on a 30-day mission to explore the planet’s atmosphere. Exploration of Venus is a challenge not only because its smog-like sulfuric acid-laced atmosphere, but also its extremely hot surface temperature and extremely high air pressure on the surface.

Quotes:
Monsignor: And I am reminded, on this holy day, of the sad story of Kitty Genovese. As you all may remember, a long time ago, almost thirty years ago, this poor soul cried out for help time and time again, but no person answered her calls. Though many saw, no one so much as called the police. They all just watched as Kitty was being stabbed to death in broad daylight. They watched as her assailant walked away. Now, we must all fear evil men. But there is another kind of evil which we must fear most, and that is the indifference of good men.::Connor: [as the brothers exit the church] I do believe the monsignor's finally got the point.::Murphy: Aye.[after Rocco shoots three men in a coffee shop]::Murphy: Liberating, isn't it?::Connor: Let's fuckin' go!::Rocco: You know, it is a bit.
Doc: You know what they say: People in glass houses sink sh-sh-ships.::Rocco: Doc, I gotta buy you, like, a proverb book or something. This mix'n'match shit's gotta go.::Doc: What?::Connor: A penny saved is worth two in the bush, isn't it?::Murphy: And don't cross the road if you can't get out of the kitchen.
[the two brothers are in an airshaft and getting a bit uncomfortable]::Murphy: Where the fuck are you going?::Connor: Shhh. I'm figuring some shit out here.::Murphy: Ahh, fuck you! I'm sweatin' my ass off draggin' your fuckin' rope around. Must weigh thirty pounds.::Connor: Shhh. We are doing some serious shit here, now get a fucking hold of yourself!::Murphy: Oh, *fuck you*! I'm not the rope-totin' Charlie Bronson wannabe that's getting us fucking lost!::Connor: Would you fucking shut it?::[taps him on the head with his flash light, and both brothers start fighting in the air vent until it gives way]::Connor: You mother- Jesus fucking Christ!::Murphy: Oh, shit!::[the vents give way]
Doc: He left me his c-c-c... He left me his c-c-c... Oh, he fucking gave me this. Fuck! Ass!
Rocco: [shouts] Fuck it! There's so much shit that pisses me off! You guys should recruit, 'cause I'm sick and fucking tired of walking down the street, waiting for one of these crack-piping, ass-wiping, motherless lowlifes to get me!::Murphy: Hallelujah, Jaffar.::Rocco: So, like, you're not just talking about mob guys, right? You're talking about pimps and drug dealers and all that shit, right?::Connor: Oh, yeah.::Rocco: Fuck. You guys could do this every goddamn day!::Murphy: We're sorta like 7-Eleven.

These are codes of behavior, and those of you that ignore them will pay the dearest cost.::Murphy: There are varying degrees of evil. We urge you lesser forms of filth not to push the bounds and cross over into true corruption, into our domain.::Connor: For if you do, one day you will look behind you and you will see we three. And on that day, you will reap it.::Murphy: And we will send you to whatever god you wish.::[Murphy and Conner join II Duce behind Yakavetta]::Connor, Murphy, Il Duce: And shepherds we shall be, for Thee, my Lord, for Thee.

Gust Tunnel
History
Langley Building 1218 was constructed in August 1945 for the purpose of conducting experiments on gust loads using free-flight models catapulted through a vertical airstream. When the gust research activity was terminated in the mid-1950s, the building occupancy was divided between research office space (designated Building 1218) and an anechoic test facility (designated Building 1218-A). The anechoic test capability was retained through 2009, while the office areas were subsequently converted to an Executive Conference Center.
Gust Tunnel
The aircraft design process devotes considerable time to ensure that the airframe structure will be the lightest and most acceptable approach to meeting requirements based on in-flight and ground-induced structural loads. One traditional challenge has been the development and validation of technical methods to predict air loads experienced during flight in gusts and turbulence. This capability is extremely important, not only from a safety-of-flight perspective, but also to prevent an over design of aircraft structures which would result in unnecessarily large weight penalties. Early research in the 1920s and 1930s at the NACA Langley laboratory included theoretical studies of loads generated in specific gust fields, but flight data to substantiate the predictions were extremely difficult to obtain at that time. In order to experimentally investigate gust loads under controlled conditions, the NACA designed and constructed a pilot gust tunnel in 1937 within an area of the Langley Full-Scale Tunnel building (Building 643) outside the tunnel flow circuit. This pilot gust-tunnel facility operated in the NACA East Area for almost a decade.

30 X 60 Full Scale Tunnel
History
Commonly referred to as the Full Scale Tunnel, Building 643 in the NASA East Area has been the site of four historically significant activities since its construction in 1930. These activities have spanned from the era of biplanes to NASA space programs. The following provides information on research activities in some of the most important programs conducted in Building 643.
Full Scale Tunnel was demolished in 2011 after many years of continuous use. (See Tribute) Artifacts from this National Historic Landmark were salvaged for displays, including the Smithsonian's Milestones of Flight exhibit. See Artifacts for a listing of salvaged items.
Full-Scale Wind Tunnel
After the Variable Density Tunnel (VDT) of the National Advisory Committee for Aeronautics (NACA) was put into operation in the 1920s, it was recognized as a breakthrough accomplishment in wind-tunnel testing technology. By using higher than atmospheric pressure in its airstream, the VDT provided aerodynamic conditions more representative of those experienced in flight. However, the relatively small size of its test section required the use of relatively small aircraft models and severely limited testing of full-scale airplane components. Powered models could not be accommodated, and the aerodynamic effects of real aircraft construction such as rivets, fabric, and other component details were difficult or impossible to simulate. Of even more concern, however, was the recognition that significant aerodynamic turbulence was present in the tunnel air flow due to the geometrical shape of the VDT. As the concern over results from the VDT began to grow, several research leaders at Langley began to advocate for a new large wind tunnel capable of conducting tests of full-scale aircraft at that time.
The NACA authorized the construction of the Full-Scale Tunnel (FST) at Langley in February 1929 and design work started immediately. Smith J. DeFrance led the design team, which also included Abraham Silverstein, Clinton H. Dearborn, and Harry J. Goett. Significantly, three of these NACA researchers later became Directors of NACA or NASA field centers...

Gust Tunnel
History
Langley Building 1218 was constructed in August 1945 for the purpose of conducting experiments on gust loads using free-flight models catapulted through a vertical airstream. When the gust research activity was terminated in the mid-1950s, the building occupancy was divided between research office space (designated Building 1218) and an anechoic test facility (designated Building 1218-A). The anechoic test capability was retained through 2009, while the office areas were subsequently converted to an Executive Conference Center.
Gust Tunnel
The aircraft design process devotes considerable time to ensure that the airframe structure will be the lightest and most acceptable approach to meeting requirements based on in-flight and ground-induced structural loads. One traditional challenge has been the development and validation of technical methods to predict air loads experienced during flight in gusts and turbulence. This capability is extremely important, not only from a safety-of-flight perspective, but also to prevent an over design of aircraft structures which would result in unnecessarily large weight penalties. Early research in the 1920s and 1930s at the NACA Langley laboratory included theoretical studies of loads generated in specific gust fields, but flight data to substantiate the predictions were extremely difficult to obtain at that time. In order to experimentally investigate gust loads under controlled conditions, the NACA designed and constructed a pilot gust tunnel in 1937 within an area of the Langley Full-Scale Tunnel building (Building 643) outside the tunnel flow circuit. This pilot gust-tunnel facility operated in the NACA East Area for almost a decade.
The pilot gust-tunnel testing technique consisted of launching dynamically scaled, free-flight airplane models through gusts of known shapes and intensities. During the flight measurements were made of the accelerations and reactions of the models due to the gusts. The test facility consisted of a gust generator, a catapult for launching the models, and two screens used to decelerate and catch the airplane model at the end of the flight...

http://en.wikipedia.org/wiki/Wind
Wind is the flow of gases on a large scale. On Earth, wind consists of the bulk movement of air. In outer space, solar wind is the movement of gases or charged particles from the sun through space, while planetary wind is the outgassing of light chemical elements from a planet's atmosphere into space. Winds are commonly classified by their spatial scale, their speed, the types of forces that cause them, the regions in which they occur, and their effect. The strongest observed winds on a planet in our solar system occur on Neptune and Saturn.
In meteorology, winds are often referred to according to their strength, and the direction from which the wind is blowing. Short bursts of high speed wind are termed gusts. Strong winds of intermediate duration (around one minute) are termed squalls. Long-duration winds have various names associated with their average strength, such as breeze, gale, storm, hurricane, and typhoon. Wind occurs on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few hours, to global winds resulting from the difference in absorption of solar energy between the climate zones on Earth. The two main causes of large-scale atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet (Coriolis effect). Within the tropics, thermal low circulations over terrain and high plateaus can drive monsoon circulations. In coastal areas the sea breeze/land breeze cycle can define local winds; in areas that have variable terrain, mountain and valley breezes can dominate local winds.
In human civilization, wind has inspired mythology, influenced the events of history, expanded the range of transport and warfare, and provided a power source for mechanical work, electricity and recreation. Wind powers the voyages of sailing ships across Earth's oceans. Hot air balloons use the wind to take short trips, and powered flight uses it to increase lift and reduce fuel consumption. Areas of wind shear caused by various weather phenomena can lead to dangerous situations for aircraft. When winds become strong, trees and man-made structures are damaged or destroyed.
Winds can shape landforms, via a variety of aeolian processes...

http://en.wikipedia.org/wiki/Aerodynamic_heating
Aerodynamic heating is the heating of a solid body produced by the passage of fluid (such as air) over a body such as a meteor, missile, or airplane. It is a form of forced convection in that the flow field is created by forces beyond those associated with the thermal processes. The heat transfer essentially occurs at the vehicle surface where aerodynamic viscous forces ensures that the flow is at zero speed relative to the body for a very thin layer of molecules at the surface.
When fluid flow slows down its kinetic energy is converted to heat; in high speed flows, tremendous energy is represented by the mean motion of the flow. As the flow is slowed to near zero speed, its temperature increases, the gradient in the speed in a direction normal to the surface allows small scale mass transport effects to dissipate the temperature in the outward direction and thus the temperature at the surface is less than the stagnation temperature; the actual temperature is referred to as the recovery temperature. These viscous dissipative effects to neighboring sub-layers make the boundary layer slow down via a non-isentropic process. Heat then conducts into the surface material from the higher temperature air. The result is an increase in the temperature of the material and a loss of energy from the flow. The forced convection ensures that other material replenishes the gases that have cooled to continue the process.
The stagnation and the recovery temperature of a flow increases with the speed of the flow and are greater at high speeds. The total thermal loading of the structure is a function of both the recovery temperature and the mass flow rate of the flow. Aerodynamic heating is greatest at high speed and in the lower atmosphere where the density is greater. In addition to the convective process described above, there is also radiative heat transfer from the flow to the body and vice versa with the net direction set by the relative temperature of each.
Aerodynamic heating increases with the speed of the vehicle and is continuous from zero speed. It produces much less heating at subsonic speeds but becomes more important at supersonic speeds. At these speeds it can induce temperatures that begin to weaken the materials that compose the object. The heating effects are greatest at leading edges. Aerodynamic heating is dealt with by the use of high temperature alloys for metals, the addition of insulation of the exterior of the vehicle, or the use of ablative material.
Aircraft
Aerodynamic heating is a concern for supersonic and hypersonic aircraft. The Concorde dealt with the increased heat loads at its leading edges by the use of high temperature materials and the design of heat sinks into the aircraft structure at the leading edges. Higher speed aircraft such as the SR-71 deal with the issue by the use of insulating material and material selection on the exterior of the vehicles. Some designs for hypersonic missiles would employ liquid cooling of the leading edges (usually the fuel en route to the engine).
Reentry vehicles
Aerodynamic heating is also a topic of concern in reentry vehicles. The heating induced by the very high speeds of reentry of greater than Mach 20 is sufficient to destroy the structure of the vehicle. The early space capsules such as those on Mercury, Gemini, and Apollo were given blunt shapes to produce a stand-off bow shock. As a result most of the heat is dissipated to surrounding air without transferring through the vehicle structure. Additionally, these vehicles had ablative material that sublimates into a gas at high temperature. The act of sublimation absorbs the thermal energy from the aerodynamic heating and erodes the material away as opposed to heating the capsule. The surface of the heat shield for the Mercury spacecraft had a coating of aluminum with glassfiber in many layers. As the temperature rose to 2,000 °F (1,100 °C) the layers would evaporate and take the heat with it. The spacecraft would become hot but not harmfully so. The Space Shuttle used insulating tiles on its lower surface to absorb and radiate heat while preventing conduction to the aluminum airframe. The compromise of the heat shield during liftoff of Space Shuttle Columbia contributed to its destruction upon reentry...

Pumice rafts are expansive masses of pumice clasts floating on the oceansurface produced by silicic shallow submarine and subaerial explosive volcanic eruptions. The goal of this project was to enhance knowledge of pumice rafts and develop accessible and practical methodologies for predicting the movement of pumice rafts in the South Pacific region. Two volcanoes in this region have recently erupted and formed pumice rafts: Home Reef volcano (Tonga) in 2006 and Havre Seamount (Kermadec Islands, New Zealand) in 2012. These raft events were used as examples to test the trajectory prediction model since they occurred during times at which high spatial and temporal resolution true color imagery were being collected and they have been frequently described in peer reviewed literature, both of which were crucial in providing validation for our models.
Project partners included Dr. Bradley Scott from GNS Science New Zealand and Dr. Greg Vaughan from the U.S. Geological Survey. They are particularly interested in learning how to predict the movement of pumice rafts for enhanced navigational advisement to maritime authorities. Remote sensing data acquired from NASA's Earth Observing System (EOS) satellites Aqua and Terra were used to image and track the pumice raft produced from the 2012 Havre Seamount eruption. Additional data acquired from NASA's EOS satellites Jason-2 and QuikSCAT were used to predict the trajectory of the pumice raft using the General NOAA Operational Modeling Environment (GNOME). GNOME is a modeling tool used to predict the possible trajectory a pollutant might follow on a body of water using wind and ocean current satellite data.
Learning more about the processes and transport mechanisms of pumice rafts is significant for a number of ecological and economic reasons. Pumice rafts pose a hazard to marine transportation as individual clasts can block seawater intake valves of large ships and cause hull damage to smaller vessels. Rafts can also be detrimental to fisheries, a large kill of deep-sea fish followed the arrival of pumice rafts during the 1984 Home Reef eruption. Additionally, rafts have the potential to introduce harmful invasive species to pristine areas as they drastically increase dispersal distances for otherwise benthic or relatively sedentary organisms. This novel and easily adaptable methodology can be used by island and coastal nations and fishery managers to forecast when and where a pumice raft will be, drastically enhancing maritime navigational warnings and response times to eventual pumice landfall.

The biggest stars burn the fastest and brightest, and when they die, they do so spectacularly, exploding as supernovae and leaving behind some of the most fantastic objects in the universe: neutron stars and black holes. In this public science talk recorded at James Madison University on April 17, 2014, Dr. Scott Ransom (NRAO/UVa) discussed how these crazy objects are created, some of their amazing properties and why we (probably!) don't need to worry about them too much here in our cozy homes on Earth.
