Microgravity Topics

  • Planets in a Test Tube

    2000April 6, 2011

    What do the racing winds on Jupiterand the snail's pace circulation of molten rock inside the Earth have in common? They're all fluids whose movements were simulated in a "planet in a test tube" flown aboard the Space Shuttlein 1985 and 1995. Results from the Geophysical Fluid Flow Cell experiments were published last month in a NASA Technical Memorandum.

  • Wonder-glass from Space

    2003Sept. 20, 2011

    Glass made of metal. Glass so clear that fibers thousands of miles long would be transparent. Glass that travels through the body to destroy cancer. These are some of the wonderous types of glass than can be formed in the weightlessness of space.

  • DNA Biosentinels

    2003April 6, 2011

    A NASA-supported researcher is learning how to snag strands of DNA and examine them one by one under a microscope.

  • Trouble with Lifshitz, Slyozov, and Wagner

    2003April 6, 2011

    A Physicstheory used to create cutting-edge "designer materials" doesn't work as scientists expect. A new experiment planned for the International Space Stationcould reveal why.

  • Living up to the Hype: Superconductors

    2003April 6, 2011

    NASA research is unlocking the amazing potential of high-temperature superconductors.

  • The Pull of Hypergravity

    2003April 6, 2011

    By spinning people in a giant centrifuge for 22 hours at a time, a NASA researcher is learning more about the strange effects of artificial gravity on humans.

  • Guiding Light

    2003Sept. 20, 2011

    A new kind of glass pane containing liquid crystal droplets might have applications ranging from improving the Internet to discovering new planets.

  • Artificial Cells

    2003Sept. 20, 2011

    NASA-supported researchers are learning to make designer cells for dehydrated blood supplies and space-age medicines.

  • Tumbleweeds in the Bloodstream

    2004April 6, 2011

    Tiny sensors, shaped like tumbleweed and small enough to fit inside a blood vessel, might one day ride to space inside astronauts' bodies, warning the space travelers when radiation is damaging their cells.

  • Have Blood, Will Travel

    2004April 6, 2011

    The radiation Astronautsencounter in deep space could put vital blood-making cells in jeopardy.
