CubeSats are small, nano satellites made for space exploration. They are launching as auxiliary payloads.
It was developed in the early 2000’s. At first, it was common in universities and among students. But, it has recently become an industry and educational institution. Government agencies and commercial groups around the world have developed CubeSats.
CubeSats have several sizes, which are based on the standard CubeSat unit 1U. A 1U CubeSat is a 10cm x 10cm x 10cm cube with a mass of approximately 1 to 1.33kg. CubeSats are cost effective. Due to their low cost of production, they attract more attention from space exploration. They have a life of 2 years, but you can constantly renew them. Therefore, the use of CubeSat is increasing every year and space explorations are now easier and faster.
