Comparison of chemical gardens grown by NASA scientists on the International Space Station (left) and on the ground (right) A chemical garden while growing Cobalt(II) chloride A chemical garden A chemical garden is a set of complex biological-looking structures created by mixing inorganic chemicals.
The first organisms in space were "specially developed strains of seeds" launched to 134 km (83 mi) on 9 July 1946 on a U.S. launched V-2 rocket. These samples were not recovered. The first seeds launched into space and successfully recovered were maize seeds launched on 30 July 1946. Soon followed rye and cotton.
Many aquatic (water dwelling) and some terrestrial (land dwelling) species use hydrochory, or seed dispersal through water. Seeds can travel for extremely long distances, depending on the specific mode of water dispersal; this especially applies to fruits which are waterproof and float on water. The water lily is an example of such a plant.
Essentially, the space farm turns the spaceship into an artificial ecosystem with a hydrological cycle and nutrient recycling. [4] [5] In addition to maintaining a shelf-life and reducing total mass, the ability to grow food in space would help reduce the vitamin gap in astronaut's diets and provide fresh food with improved taste and texture.
Researchers believe the cavity was formed by an ancient supernovae.
The new findings indicate that water evaporated and left behind brines that resemble the salty crusts of dry lakebeds on Earth. More: High resolution photos of asteroid materials revealed.
Platy structure is usually found in subsurface soils that have been subject to leaching or compaction by animals or machinery. The plates can be separated with a little effort by prying the horizontal layers with a pen knife. Platy structure tends to impede the downward movement of water and plant roots through the soil.
But to the International Space Station (ISS), which is hurtling through space about 250 miles above the surface of Earth, our big planet can look kind of small. Houses, roads, and buildings all ...
