A new kind of miniature satellite has been developed by scientists. It is named as CubeSat that can be exercised in space by exposing it to water vapor. The low – cost microsatellites and nano satellites have become prevalent than conventional spacecraft.
There are a variety of tasks from high resolution imaging and internet services to disaster response, environmental monitoring and military surveillance that are set for thousands of miniature satellites after their launch. These satellites provide an opportunity for new missions such as constellation flying and exploration. The larger counterparts of these satellites cannot economically be achieved. It was said by Alina Alexeenko who is a professor at Purdue University in the U.S. CubeSats need micro-propulsion devices to give away precise low – thrust “impulse bits” for scientific, commercial and military space applications. This will also help these in achieving their full potential.
The researchers also said that the new micro-propulsion system will use ultra-purified water. Film – Evaporation MEMS Tunable Array (FEMTA) thruster is the new system which uses capillaries to harness the microscopic properties of water.
