This weed is exploited by many scientists worldwide. In the world conference for Nutrition in 1974 the United States announced Spirulina the best future alternative food source. It is many years now that many experiments are done for its use as food by astronauts in spaceships and space stations throughout space missions. NASA and other cooperative National Space Services plan a “Controlled Ecological Support System” that will cater for oxygen and food to astronauts and also recycle the waste by use of some bacteria, during their inter-planet journeys. Similar to that is a European program called MELISSA,which is supported by European Space Authority (ESA). In this life support system, the development of micro organisms is speculated. Amongst them, it is Spirulina that plays the main role.
