A classic laboratory investigation is being conducted aboard the International Space Station to better understand gravity’s impact on nanotube growth in chemical gardens. Here on Earth, colorful crystal chemical gardens are often used to teach students about phenomena like hydrothermal vents and chemical reactions. Although completely inorganic, these gardens resemble plants and are influenced in their development by the pull of gravity.

Although completely inorganic, these gardens resemble plants and are influenced in their development by the pull of gravity.
This investigation aims to increase our understanding of gravity’s impact on their structural formation.

Chemical gardens form when dissolvable metal salts are placed in an aqueous solution
containing anions such as silicate, borate, phosphate, or carbonate.

NASA Commentator Lori Meggs talks to scientists at NASA's Glenn Research Center about OASIS, Observation and Analysis of Smectic Islands in Space.

This study on the International Space Station, aimed at learning more about the unique behavior of liquid crystals in microgravity, could change the future of cell phone and television liquid crystal display screens.
