A little about the Kalamsat satellite

ISRO launched Kalamsat, a 10-cm cube-sized communication satellite, for free.

The nanosatellite was designed and built at a cost of Rs. 12 lakh by some students working with Chennai-based Space Kidz India. The students were led by 18-year-old Rifath Sharook of Tamil Nadu's Pallaptti.

Kalamsat, the first satellite to use PSLV-C44's fourth stage (PS4) as an orbital platform, is also the first-ever 3D-printed satellite.
