The Indian Space Research Organization scanner will scrutinize the solar eclipse, which will appear on 15th January, Friday.

An array of mini-rockets from Sriharikota launch pad in Andhra Pradesh and Thumba rocket launching centre in Kerala would be unleashed by ISRO, in order to study the eclipse in detail.

Spokesperson for ISRO, S Satish, explained that instruments to measure the physical parameters of the upper atmosphere and study the effects of the solar eclipse, would be carried by the rockets.

The experts say that the Friday's solar eclipse will most probably last till 12 minutes and will be the longest annual solar eclipse of this millennium.

It will be on 3rd June, 2114 when the next total solar eclipse will fall.
