Microgravity Space is the laboratory of the next millennium Astronaut Joe Allen with his morning orange juice on an early Shuttle mission The microgravity environment of space offers a unique environment to perform research with the potential to lead to new products and technologies. Microgravity provides an opportunity for experimentation in a whole new quiescent environment: no thermally-induced convection no sedimentation/stratification no hydrostatic pressure reduced contact with vessel walls Microgravity has been a major area of research in the space programs of all space faring nations, and will revolutionize traditional Earth-bound processing methods. The potential scientific, technological and commercial benefits of microgravity research to humankind are substantial, especially in the biomedical and drug development sectors.

I'm interesting: science fiction, fantasy, astronomy and physics. News October 20, 2010 We apologize about the downtime. We should have some new workunits by Monday. Thanks! May 21, 2010 Work has arrived. The workunits should take 2 to 6 hours at most. These should fix the problems with the previous workunits. March 29, 2010 uFluids will be out of work for a day or so, while the existing data is being processed. Thanks for your patience. June 12, 2009 We've been having some problems with the new workunits. We'll keep you posted. Once this is finished, We'll look into the pending workunits as many of you have requested.

Although the first demonstration is best done by the teacher, the other demonstrations can be done as activities by students working in groups of three or four. Each demonstration requires a clear space where drop tests can be conducted. Two of the demonstrations require water and you should have a mop, sponges, or paper towels available to clean up any mistakes.

Microgravity - Definition Astronauts on the International Space Station display an example of weightlessness Weightlessness is the experience (by people and objects) during freefall , of having no weight . This condition is also known as microgravity (see below). Weightlessness in common spacecrafts is not due to an increased distance to the earth; the acceleration due to gravity at an altitude of, say, 100 km is only 3% less than at the surface of the earth. Weightlessness means a zero g-force or zero apparent weight ; acceleration is only due to gravity, as opposed to the cases where other forces are acting, including: standing on the ground, sitting in a chair on the ground, etc. (gravity is cancelled by the reaction force of the ground) flying in a plane (gravity is cancelled by the lift the wings provide) - see below for special trajectories which form an exception atmospheric reentry landing on a parachute : gravity is opposed by atmospheric drag during an orbital maneuver in a spacecraft : the rocket provides thrust The difference is that gravity acts directly on a person and other masses, just like on the vehicle, while forces like atmospheric drag and thrust first act on the vehicle, and through the vehicle on the person. In the first case the person and the vehicle floor are not pushed toward each other, while in the other cases they are.

We have often seen pictures of astronauts floating around inside the space shuttle International Space Station or Mir . While weightlessness looks like fun, it places great demands on your body. Initially, you feel nauseated, dizzy and disoriented. Your head and sinuses swell and your legs shrink. In the long term, your muscles weaken and your bones become brittle. These effects on your body could do severe damage on a long voyage, such as a trip to Mars In this edition of HowStuffWorks , we'll take you on an extended journey aboard the International Space Station, where we will examine what weightlessness is, what happens to your body, how these changes come about and what can be done to prevent or reverse these adverse effects.

RSS Feeds All Wired Top Stories Magazine Wired Blogs Video News for Your Neurons Making Babies in Space May Be Harder Than It Sounds By Brandon Keim Categories: Biology Space Experimental mouse breeding in a near-zero-gravity space simulation suggests making babies is best left to Earthlings. The experiment, published Tuesday in Public Library of Science ONE , is the latest addition to a surprisingly large body of literature on how the space environment affects the cellular basics of reproduction. Among the animals that have been bred in space are frogs salamanders sea urchins fish . (Birds and bees are, understandably if unfortunately, not on the list.) To test these effects, the researchers artificially fertilized mouse eggs with sperm that had been stored inside a three-dimensional clinostat , a machine that mimics weightlessness by rotating objects in such a way that the effects of gravity are spread in every direction. Some were ultimately implanted in female mice and survived to a healthy birth, but at lower numbers than a regular-gravity control group. Part of the difference could be the result of performing tricky procedures on sensitive cells, but the researchers suspect they also reflect the affect of a low-gravity environment on cellular processes that evolved for Earth-specific 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.

Printer-Friendly Page Get Space Research News Delivered to Your Inbox! January 22, 2004 : Video feeds from the International Space Station (ISS) invariably show crew- members exercising in the background. Exercise is serious business on the ISS because microgravity causes skeletal muscles to lose power and stamina. Workouts help astronauts fight back. Yet despite rigorous workouts, astronauts return to Earth shockingly weaker than when they left. Only 11 days in microgravity may atrophy (shrink) muscle fibers as much as 30 percent and cause soreness as damaged muscles tear while readjusting to Earth's gravity. Above : The presence or absence of gravity affects skeletal muscle tissues, as shown in these two electron micrographs of human soleus muscle cells before and after 17 days in microgravity. Preflight, gravitational load stimulates the production of proteins that keep muscle fibers strong and symmetrical (A). After 17 days in microgravity (B), greatly reduced load on skeletal muscle has slowed protein production in the individual muscle cells, and they have grown more irregular and fragile as they atrophy. The prevalence of white lipid droplets (L) indicates that in microgravity, muscles build fat stores instead of using them for energy.
