SLOSHSAT-FLEVO is a microsatellite launched to investigate the dynamics of fluids in microgravity. FLEVO stands for Facility for Liquid Experimentation and Verification in Orbit. Multiple sensors were used to monitor the behavior of water in an instrumented tank and how sloshing affects the attitude control of launchers and space vehicles.[1]
The project is a joint program between ESA, the Netherlands Agency for Aerospace Programmes, and the Israel Space Agency.[3] The primary contractor is the National Aerospace Laboratory providing the spacecraft structure and power systems. The ejection system and ground support equipment were contracted by NEWTEC. The ISA was responsible for supplying the sub-propulsion system which was built and assabmled by Rafael.
Spacecraft
The spacecraft itself is a 90-cm cube microsatellite covered by solar cells and fitted with 12 small thrusters.
Launch
The satellite was set to be launched from the Guiana Space Centre launch site at Kourou, French Guiana on 12 February 2005.
Experiment
The SLOSHSAT-FLEVO is the first satellite entirely dedicated to liquid research in space. The satellite was equipped with an 87-litre cylindrical tank containing 33.5 litres of de-ionised water. 270 sensors were placed on the tank's walls to measure the sloshing behavior by calculating the thickness of the water. Three accelerometers and a fibre-optic gyroscope were used to measure the motion of the spacecraft. An array of temperature, pressure and fluid velocity sensors were also installed on the craft.[1][3]
