42. Microgravity Programme Overview microgravity programme overview, http://www.estec.esa.nl/spaceflight/mygpov.htm

Microgravity programme overview Quick access: EMIR-2 MFC Microgravity Application Promotion (MAP) Introduction Research under microgravity conditions has been undertaken in Europe for the past 15 years, both through ESA's microgravity programmes and initiatives at national level. The past and present research programmes highlight high microgravity can be a useful and unique tool for the study of physical, chemical and biological processes that are important in science, engineering and technology. ESA's role in microgravity research The European Space Agency supports European research under microgravity conditions through the following activities: ESA develops multi-user experiment facilities needed to perform microgravity research in space by the various user communities (life sciences, physical sciences, material sciences, etc.) ESA develops the spacecraft on which these facilities can fly (e.g. Spacelab, Columbus) or provides flight opportunities for these facilities on spacecraft of other space agencies or industrial contractors (e.g. Foton, sounding rockets, Spacehab, US Laboratory of the International Space Station) ESA, in so-called "Announcements of Opportunity" informs the interested user community about the availability of experiment facilities on space missions or on the ground (drop towers, zero-g aircraft) and calls for experiment proposals

43. Bauanleitungen Für Hamstergehege Und Hamsterkäfige Anleitungen mit Text und Fotos f¼r den Bau von Gehege und K¤fig sowie Tipps zur Einrichtung werden geboten. http://www.microgravity-systems.com/hamsterparadies/

Hauptseite Bauanleitung Hamsterbau Fotoalbum ... Links Hauptseite Diese Seite behandelt optimierten (Zwerghamster)gehegebau. Unter " Bauanleitung " findet man einen kompletten Plan mit einigen Bildern, Skizzen und einer Animation zum Zusammenbau. Das Grundprinzip ist das folgende: Der Käfig ist verhältnismäßig groß und bietet den Bewohnern ein weite Lauf- und Wohnfläche. Aufgrund der Größe kann das Gehege nicht einfach transportiert werden, so dass er an Ort und Stelle gereinigt wird. Dazu kann man (ermöglicht durch die Konstruktion) die Einstreu einfach herausfegen und die Flächen mit Wasser oder leicht Essigsaurem Wasser abwaschen. Das Hamster Gehege kann mit Dekorationen und Gängen auf Styropor / Betonbasis versehen werden (" Hamsterbau "), so dass ein plastischer und biotpopähnlicher Eindruck entsteht. Die Hamster haben somit einen Lebensraum zur Verfügung, der ihrem natürlichen schon recht nahe kommt - auf jeden Fall wesentlich näher als den handelsüblichen bunten Plastikkäfigen. Bepflanzt wird das Ganze dann natürlich auch.

45. Microgravity Research Program - What Is Microgravity Understanding Gravity and microgravity Brief periods of microgravity canbe achieved on Earth by dropping objects from tall structures. http://microgravity.nasa.gov/wimg.html

Understanding Gravity and Microgravity Isaac Newton In his "thought experiment," Isaac Newton hypothesized that by placing a cannon at the top of a very tall mountain and firing a cannonball at a high enough velocity, the cannonball could be made to orbit the Earth. Gravity is such an accepted part of our lives that we rarely think about it even though it affects everything we do. Any time we drop or throw something and watch it fall to the ground, we see gravity in action. Although gravity is a universal force, there are times when it is not desirable to conduct scientific research under its full influence. In these cases, scientists perform their experiments in microgravity - a condition in which the effects of gravity are greatly reduced, sometimes described as "weightlessness." Any object in freefall experiences microgravity conditions, which occur when the object falls toward the Earth with an acceleration equal to that due to gravity alone (approximately 9.8 meters per second squared [m/s2], or 1 g at Earth's surface). Brief periods of microgravity can be achieved on Earth by dropping objects from tall structures. Longer periods are created through the use of airplanes, rockets, and spacecraft. The microgravity environment associated with the space shuttle is a result of the spacecraft being in orbit, which is a state of continuous freefall around the Earth.

High Tea Posted April 8, 2003 ISS Expedition 6 Science Officer, Don Pettit, It's a competition: surface tension vs. gravity. Surface tension holds droplets of water together. Gravity pulls them apart. On Earth, gravity usually wins. Only small droplets have enough surface tension per unit mass to remain intact. Onboard the International Space Station (ISS), however, surface tension rules. Weightless water can form big floating drops, large enough to quench your thirst and tough enough to handle using chopsticks. ISS science officer Don Pettit paused for afternoon tea and showed us how it's done: "It's easy," says Pettit. "You just take your chopsticks, pick up a blob of tea, and pop it in your mouth. This is a practical demonstration of all the surface chemistry we learned about in college." Because fluid droplets onboard the space station are undisturbed by their own weight, they make marvelous research tools for investigations in basic fluid physics.

Candle Drop Worksheet MATERIALS AND TOOLS Clear plastic jar and lid (2 liter volume)* Wood block Screws Birthday candles Matches Drill and bit Video camera and monitor (optional) Eye protection * Empty 3-lb plastic peanut butter jar can be used. A burning candle is encased by a clear plastic jar and dropped for a study of flames in microgravity. Activity Management: Before attempting this activity, be sure to conduct the Candle Flames activity. Doing so will sharpen the observation skills of the students. This is important because, in this activity, students will be observing the size, shape, and color of a candle flame as it is falling. Investigating candle flames in microgravity can be done as either a demonstration or an activity. If used as a demonstration, only one candle drop jar is necessary. If used as an activity, one candle drop jar is needed for each student group. Clear plastic food storage jars are available at variety stores, but plastic peanut butter jars will work as well. The jars should be 1 quart or half gallon size (3 pound size if peanut butter jars are used). The oxygen supply in smaller jars runs out too quickly for proper observations.

welcome to microgravity.net This is the home of microgravity plasma experiments Plasma experiments with microgravity include: PKE (Plasma Crystal Experiment) 1997 - present Sounding Rocket Experiments (MPE) Parabolic Flight Tests (MPE) MIR experiment (HEDRC) IMPF International Microgravity Plasma Facility The jargon: "M icrogravity " means the condition of near-weightlessness that can be achieved in spaceflight, as well as in parabolic aircraft flights and drop towers. A " plasma " is an ionized gas containing free electrons, ions, and neutral gas. For most plasmas under laboratory conditions, gravity is not a significant factor. However, in the field of " complex plasmas ," or " dusty plasmas " as they are also known, gravity is a major disturbance. A " complex plasma " consists of a normal plasma plus small particles of solid matter, which gain a large electric charge. The term "complex plasma" is used in analogy to " complex fluids ", which is the field of condensed matter involving colloidal suspension and similar media containing small particles. The science: In a complex plasma, particles interact with one another with a shielded Coulomb interaction. The can be trapped in a stable equilibrium by the natural electric fields in the plasma. They are imaged with a camera and laser illumination, so that we can see every particle in the suspension, and record their positions and velocities. Under laboratory conditions with particles larger than a micron, gravity causes sedimentation of the particles, forming a thin horizontal layer at the bottom of the plasma. While many exciting experiments are done using these laboratory systems, there are a whole class of experiments in three dimensions which are enabled by eliminating gravity. These scientific topics include, for example, crystalline structure, the melting/freezing transition, defect structure and dynamics, fluid interface phenomena, shocks, waves, and instabilities.

Marshall Space Flight Center Home Highway to Space Science Space Projects ... Privacy Statement What is Microgravity? Contrary to popular belief, Earth’s gravity still has an effect on a spacecraft that is orbiting Earth. When in orbit around Earth, a spacecraft has escaped only 10% of Earth’s gravitational pull. So why does everything appear to float? Objects that are in orbit around Earth are actually in a continuous state of freefall. This state of freefall is called low-gravity, or microgravity, because the effects of gravity have been greatly reduced. This unique environment allows scientists to conduct research that achieves results not possible in ground-based laboratories. The Program Marshall is the lead center for NASA’s Microgravity Research and Space Product Development programs. Current microgravity research studies includes the investigations of some of the most deadly diseases known to man and studies of the fundamental mysteries of the universe. The scientific disciplines of microgravity research are biotechnology combustion science fluid physics fundamental physics , and materials science The Space Product Development (SPD) program seeks to partner NASA with industry and academia in order to use space to develop improved products and services. The program is implemented through Research Partnership Centers (RPCs) that perform research in drug design, materials processing, and agriculture.
