Sloshsat FLEVO (Facility for Liquid Experimentation and Verification in Orbit) is a small satellite that will be ejected from NASA's Space Shuttle to investigate the effects on a manoeuvring spacecraft of 33.5 litres of water sloshing in a 90-litre tank. It is a harmonised programme between ESA and the Netherlands Agency for Aerospace Programmes (NIVR). The main contractor is the Dutch National Aerospace Laboratory (NLR), supported by Fokker Space, Verhaert, Newtec, Rafael and NASA. Development is being performed within ESA's Technology Development Programme (TDP) Phase-2 and the NIVR Research & Technology (NRT) programme. [Image Date: 1998] [98.09.007-002]
