As India`s first moon lander Vikram is all set to land on the moon on early on Saturday, Tamil Nadu`s Sona College revealed its Special Electrical and Electronics Drives Division (SPEED) supplied three products that are its parts, including two vital components that will allow its smooth landing on the moon and collection of soil and rock samples.

These products are the fuel mixer motors that mix liquid oxygen with fuel, the Doppler mechanism for Vikram module to guide the laser to ensure smooth landing on the moon and the Sona Mechanical Research team-built robotic arm for picking sand and rock samples from the moon, the Salem-based institution told IANS.
