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 b ecoming a commercial venture. Indian Space Research Organization (ISRO) is planning to promote micro-gravity research in the country by providing a su itable platform for scientists to conduct experiments in various fields. Th is paper presents the details of a comprehensive study undertaken at ISRO S atellite Centre, Bangalore and suggests the following two options: to devel op a recoverable and reusable satellite as a long-term goal and to make use of stratospheric balloon-drop tests for immediate use by scientists to gai n hands-on experience in designing and conducting microgravity experiments.
