Extractions: Microgravity Science Glovebox MSAD Home Glovebox Overview Capabilities Components ... Glovebox Contacts MICROGRAVITY SCIENCE GLOVEBOX OVERVIEW The Microgravity Science Glovebox (MSG), located in International Space Station US Lab Destiny module, enables scientists from multiple disciplines to participate actively in the assembly and operation of experiments in space with much the same degree of involvement they have in their own research laboratories. Developed by the European Space Agency (ESA) and integrated by NASA's Marshall Space Flight Center (MSFC), the MSG was launched to the ISS in June 2002. This facility offers an enclosed 255-liter work area that is accessible to the crew through sealed glove ports and to ground-based scientists through real-time data links and video. Because the MSG work area can be sealed and held at a negative pressure, the crew can manipulate experiment hardware and samples without the potential hazard of small parts, particulates, fluids, and gasses escaping into the open laboratory module.

Microgravity microgravity is the name that has been adopted for very high resolution gravity mapping. microgravity surveys are typically used http://www.esci.keele.ac.uk/geophysics/Research/Gravity/
Extractions: 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 earths 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?....

Splashing In Microgravity Splashing in microgravity, Under its Undergraduate Opportunities Research Program, NASA accepts proposals from undergraduate students http://www.apl.washington.edu/edu_opportunities/undergrad_research/microgravity.
Extractions: Under its Undergraduate Opportunities Research Program, NASA accepts proposals from undergraduate students to conduct experiments on board its KC-135A, the military equivalent of a Boeing 707, used to train astronauts. During the experiments, the aircraft cycles between g and 2 g in a parabolic trajectory. The high incidence of motion sickness has earned the aircraft the nickname "Vomit Comet." Under the supervision of APL-UW Senior Physicist John Wettlaufer, Lisa Couret and 1998 Hardisty Scholar Dorothy Caplow, both physics majors, conducted an experiment to determine what happens when a drop of fluid hits a fluid surface. The experiments were designed to investigate the effect of gravity on the transition between splashing and coalescing drops and the effect on the characteristic "crown of thorns" produced by a splashing drop. The characteristic shape and evolution of the resulting space depend on the balance of capillary, inertial, and gravitational forces. Under microgravity conditions, the effects of surface tension dominate, and the resulting interplay between capillary and inertial forces can create effects impossible in 1 g . Because of the complicated, nonlinear nature of the problem, these effects are difficult to model or predict beforehand.

Extractions: Our Mission The Microgravity Data Archive is a database that contains both Experiment Data Management Plans (EDMPs) and any papers/publications/presentations that were generated from both combustion and fluids experiments (flight and ground based). The EDMPs contain information for flight experiments such as: Project Scientist, summary of the experiment, what data was collected during the experiment, what data is available from the experiment, and what the results of the experiments were. Also included on the EDMPs is a list of what publications/presentations were written about the experiment. The publications/presentations information available includes the author, title, where and when it was published, and the abstract from the paper.

Biological Crystal Growth In Space - What Is Microgravity NASA s Biological Crystal Growth Program this site contains current and historical information on the microgravity protein crystal growth program. http://crystal.nasa.gov/general/whatis_mg.html
Extractions: What is Microgravity The term "Microgravity" is really a misnomer. The force of gravity in low Earth orbit is more than 90% of the force of gravity at the Earth's surface. To reach a point where Earth's gravity is reduced to one-millionth of that on Earth's surface, one would have to be 6.37 million kilometers away from Earth (almost 17 times farther away than the Moon). A spacecraft in orbit, however, is in a state of free-fall that produces weightlessness. A circular orbit results when the centripetal acceleration of uniform circular motion (v2/r; v = velocity of the object, r= distance from the center of the object to the center of the Earth) is the same as that due to gravity alone. In other words, the gravitational force acting on the spacecraft center of mass is balanced by the centrifugal force produced in the orbital trajectory. The acceleration of a payload within the spacecraft relative to the spacecraft itself is reduced orders of magnitude compared to g (9.8 m s-2). At the center of mass of the spacecraft the acceleration is reduced to zero (neglecting atmospheric drag). So, more accurate terms would be "free-fall" or "near weightlessness", but the term "microgravity" has stuck. Both external and internal forces give rise to accelerations at points within the spacecraft.
