Microgravity research platforms: A study

Materials processing in space, based on the research undertaken during the past three decades by the leading space-faring nations is on the verge of becoming a commercial venture. Indian Space Research Organiration (ISRO)is planning to promote microgravity research in the country by providing a suitable platform for scientists to conduct experiments in various fields. This paper presents the details of a comprehensive study undertaken at ISRO Satellite Centre, Bangalore and suggests the following two options: to develop a recoverable and reusable satellite as a longterm goal and to make use of stratospheric balloon-drop tests for immediate use by scientists to gain hands-on experience in designing and conducting microgravity experiments.
