The availability of sensors suitable for Space Explorations are very less due to lack of investment in the area. The future for space missions to explore more features of our incredible solar system is mainly compromised by the new advancements in the area of military or warfare. Therefore, some scientists from different parts of world mainly USA , Russia , China and India are trying to create what we call smart sensors. [1] They have created the model of their system and also tested it in famous Jet Propulsion Laboratory, California sponsored by National Aeronautics and Space Administration  but cannot make the mass production due to financial reasons and lack of investors. Its ultra fast processing system mimics what is inherent in biological systems which is used to take the real time decisions, all by themselves out there in the space.[2] •	What is the difference between normal sensors and space sensors? [3] 	Normal sensors don’t have to undergo huge amount of wear and tear. 	Temperature out in space are very large than on Earth. 	 Huge amount of radiations are present to distort your signal such as cosmic rays or solar waves. 	Maintenance of these sensors cannot be done in space.

•	What is a Smart Sensor? 	The real time sensors that can take their decisions by themselves, without the need of a guide. 	These sensors are based on the Eye-Brain model of a Human, that can take their decisions on their visual inputs.

•	Why we need Smart Sensors?[2] 	The primary reason is their processing speed and their self decision making mechanism. 	The secondary reason is that the time taken to exchange crucial information between the robot and operators which are sitting here on Earth. Usually the time gap for a Robot to send and receive the info from Mars is about 1 hour(depending on the position of Mars and Earth).

	About 50% of sensors are temperature sensors used to control the temp. of the satellite and 30% are used to monitor the voltage and status of the components. Thus to these huge amount of sensors by a single Smart Sensor is both beneficial and economic.
