Chandrayaan, series of Indian lunar space probes. Chandrayaan-1 (chandrayaan is Hindi for "moon craft") was the first lunar space probe of the Indian Space Research Organisation (ISRO) and found water on the Moon. It mapped the Moon in infrared, visible, and X-ray light from lunar orbit and used reflected radiation to prospect for various elements, minerals, and ice. It operated in 2008–09. Chandrayaan-2, which launched in 2019, was designed to be ISRO’s first lunar lander.

The spacecraft carried 11 scientific instruments built in India, the USA, UK, Germany, Sweden, and Bulgaria. .

Suppose there are n people in the party. The first person shakes hand with the other (n-1) guests. The second guest shakes hand with the other (n-2) guests. this will continue until the (n-1)-th guest shakes hand with the nth guest.

Total number of handshakes is (n-1) + (n-2).. + 3 + 2 + 1. .

= (n-1)(n)/2 .

For example, 6 people in a party shake hand with other guests. So how many handshakes will be there?.

=(6-1)(6)/2.

=15.
