Summary
SLOSHSAT, also known as Sloshsat-FLEVO, is an experimental satellite launched by ESA on February 12, 2005, from the Guiana Space Center using an Ariane 5ECA launch vehicle. The spacecraft has a box shape with dimensions of 1 meter in length and diameter of 0.7 meters, and its dry mass is 70 kilograms. It was designed to study technology fluids in weightlessness conditions. SLOSHSAT carries an equipment payload consisting of an 87-liter water tank containing 33.5 kg of water for experiments. The satellite's propulsion system includes 12 cold gas thrusters, and it uses solar cells and batteries as its power source. The mission was intended to last approximately 10 days, providing valuable data on fluid behavior in microgravity environments.
