The mission to Venus, hy the Galileo spacecraft in 1989-90, produced relatively modest new data. The mission s primary objective was the planet Jupiter, and a visit to Venus was included only to provide a "gravity assist —a way to give the spacecraft the impetus it needed to get to the outer planet. During its closest approach of about 10,000 miles (16,000 km) from the planet, however, Galileo was able to carry out additional spectroscopic studies of Venus s clouds, collect photographs of its middle atmosphere clouds, and analyze radioactive sources present in the clouds. 

The 3-D woven fabric reinforced foam composite panel was fabricated in a steel mold using a gravity assisted method by impregnating the 3-D woven fabric with the uncured foam. The...

Like the other methods, the main purpose of dialysis and electrodialysis is the separation of small and large molecules it is often used for desalting purposes. These are based on the phenomenon that certain compounds can diffuse through a semipermeable membrane, while others cannot. This differentiation is mainly based on molecular size. The principle of dialysis is, in fact, quite similar to ultrafiltration the driving force is not only gravity (assisted by centrifugation) but also osmotic pressure.
