Home Discover DFTV Earth and Space Who doesn't love rollercoasters? We could spend days on them! Your stomach jumps into your throat and you feel like you're floating. That feeling is weightlessness, which is kind of like what astronauts feel in space. Astronauts call it microgravity, because during the fall you feel only a tiny amount of gravity's pull. We wondered: how do ordinary things behave in microgravity? We searched NASA's Web site and found a way to test what microgravity is like. We made a "drop box" from a regular plastic storage container. We dropped it over a ledge and into an inflatable swimming pool. The height of the ledge was about 5 meters, enough to give us about 1 second of microgravity. We put a fizzing seltzer tablet in the drop box to see what happens to bubbles in microgravity. Second, we put a walking wind-up toy in the box, to see what it does. Last, we wondered what it would be like to ride on a swing in space. We put a small swinging pendulum in the box. We had a wireless video camera inside the box so we could see what happened during the drop. We played back the video in slow motion. Before the drop, we saw the fizzy bubbles rising. Then they just stood still during the drop! Bubbles don't float up in microgravity! The walking toy walked like normal during microgravity, although it started to lift up off the floor of the box a little bit, like it was floating. The swinging pendulum was swinging back and forth right before the drop, but then the pendulum swung all the way around in one direction in microgravity.

Gravity is a force that governs motion throughout the universe. It holds us to the ground, keeps the Moon in orbit around the Earth, and the Earth in orbit around the Sun. Many people mistakenly think that there is no gravity above the Earth's atmosphere, i.e., in "space," and this is why there appears to be no gravity aboard orbiting spacecraft. Typical orbital altitudes for human spaceflight vary between 192 and 576 km above the surface of the Earth. The gravitational field is still quite strong in these regions, since this is only about 1.8% the distance to the Moon. The Earth's gravitational field at about 400 km above the surface maintains 88.8% of its strength at the surface. Therefore, orbiting spacecraft, like the Space Shuttle or Space Station, are kept in orbit around the Earth by gravity. The nature of gravity was first described by Sir Isaac Newton, more than 300 years ago. Gravity is the attraction between any two masses, most apparent when one mass is very large (like the Earth).

Microgravity Fiber-Pulling Apparatus Discuss this and other technologies with colleagues at the Reader Forum This fiber-processing method provides a way to produce optical fiber composed of glass systems in microgravity. Marshall Space Flight Center, Alabama A method to process optical fiber composed of glass systems has been developed in support of the space shuttle and Space Station programs. This process, known as the Microgravity Fiber-Pulling Apparatus, was designed to operate in a microgravity environment. It has the unique capability to produce heavy-metal glasses through the reduction of nucleation and allows low viscosity to be handled more easily. Optical fibers, such as the heavy-metal fluoride glasses, are usually very difficult to process in ground-based operations because the glass has inherent characteristics such as low viscosity, a narrow working range, and a tendency to form crystallites during processing. Operation in microgravity has demonstrated that some of the conventional methods used in Earth-based fiber-forming processes will not function properly in a weightless environment. For example, the gravitational force necessary to initiate the fiber draw is not present in space. The components of this fiber-pulling apparatus include a source of the glass (preform), a sting to initiate the fiber-drawing process, a coating applicator for ultraviolet-curable cladding, an ultraviolet lamp, and a reel to place the drawn fiber on after it has been cooled. These components are shown in the figure.

Fluid Mechanics in Zero-Gravity This work involves a phenomenon of broad scientific and practical interest: The tuning of splash ejecta. Many people have seen Edgerton's 1954 high-speed photographs of a drop hitting a liquid surface which creates a "crown of thorns" produced by the impact. The height of the central "Worthington jet" can be tuned via the velocity of the impactor and the thickness of the target fluid. Physics undergraduates Dorothy Caplow and Lisa Couret have investigated how Edgerton's experiments would need to be done in the absence of gravity. The images below show some results of their experiments on NASA's Boeing KC-135A turbo jet parabolic flight program. Small droplets (4 mm in diameter) are launched into a liquid film ( 8 mm in depth) and their dynamics are captured on high-speed video. The flights allowed approximately 30 seconds of zero gravity and similar intervals of 2 g. The initiation of the aircraft free fall creates inertial ringing in the fluid superposed upon which is a higher frequency "g-gitter". Dramatic changes are seen in the height of the Crown and the Worthington jet relative to those in 1 g. (1) In zero gravity, a drop launched at a source fluid of saline solution. The fluid container has a diameter of 4 inches.

As with other applications the method focuses on missing mass. Therefore, microgravity can and has been utilised in the search for burial chambers and associated tunnels. As the method of data collection is totally passive archaeologists need not fear any form of disturbance over sensitive sites. top C Microgravity is the only surface geophysical method that will provide the location of such karstic features regardless of their shape or fill provided a sufficient density contrast exists. Cavities constitute a considerable hazard to development and redevelopment and any migration to the surface may seriously damage property and services.

Research Microgravity This site introduces basic concepts of gravity, from Newton to Bouguer, and allows the user to perform a selection of surveys and to calculate the gravity anomaly over a void. The applications section shows that microgravity technology is not restricted to cavity detection. A series of recent case studies are also provided to illustrate the power of the technique. More specific advice is always by contacting us. Microgravity is a geophysical method that measures minute changes in the force of the earth’s gravity. With modern equipment and careful field procedures it is now possible to measure gravity changes as small as 1 part in 1,000,000,000. Changes in gravity measured at the earths surface reflect the underlying geological structure, hence the accurate determination of gravity leads to an understanding of the ground beneath. It has been established that microgravity is an accurate and reliable method for detecting underground cavities, both natural and manmade. The application of this technique however is not restricted to void detection. High resolution gravity has been used to monitor fluid flow in oil and geothermal reservoirs and to monitor aquifer recharge and depletion. Traditional gravity surveying as used in the oil and minerals industries has been given greater resolution by the use of microgravity acquisition and processing methods. Did you know?....

Contact AEM For the a number of years, we have had two AEM student teams from the University of Minnesota , one group in fluids area and the other group in the solids/materials area, participate in the Reduced Gravity Student Flight Opportunities Program sponsored by NASA's Johnson Space Center. Students design experiments to be performed on the NASA KC-135 aircraft, which is used for astronaut training, as well as experiments, which require short periods of reduced gravity. The students typically travel to Texas to undergo training around March or April each year, for a nine-day period. During this time period, they perform their inflight experiments while the aircraft is performing maneuvers which produce microgravity for about 30 seconds. The flight path of the aircraft is like a roller coaster and student will experience relatively large "g" forces as well as reduced gravity. Students that have participated in the program the last several years have found the ride very exciting and the experience of a lifetime. Yearly projects of the students are listed below. This experience is now available commercially.

The Drop Tower Microgravity Demonstrator Jeffrey C. LaCombe Materials Science and Engineering Department, Rensselaer Polytechnic Institute, Troy, NY 12180 Modern research-scale drop towers provide scientists with brief periods of low-gravity free-fall conditions in which a wide variety of scientific experiments can be conducted. It is shown here that affordable classroom-scale drop towers can assist in science education by demonstrating a wide range of physical principles in a high-impact, attention-getting manner. The equipment described here can be constructed for as little as a few hundred dollars, and when combined with readily available televisions and video tape recorders, make an excellent classroom teaching aid. Introduction The concept of a portable classroom drop tower was first popularized by (if not introduced by) NASA’s Lewis Research Center. The Microgravity Demonstrator apparatus, described by Rogers and Wargo [ ] is a portable and compact demonstration kit that fits entirely into a trunk—television and all. While of excellent design, the NASA hardware is largely custom-machined, is expensive, and in short supply. Rogers and Wargo offer some basic advice on building your own drop tower, which can be found in the above referenced description of the Microgravity Demonstrator The design described here picks up where the original NASA design leaves off by providing a portable, yet inexpensive and easy to construct apparatus. Some schools have televisions and video tape recorders already available, allowing costs for the drop tower to be limited to as little as $200 to $300 (for parts) depending on the choice of the video camera.
