ISRO launched the lightest satellite "Kalamsat-V2"

Indian Space Research Organisation (ISRO) has launched the Kalamsat-V2 from Sriharikota Space Centre.

About Kalamsat-V2:

• The satellite is named after former President and Indian scientist Dr A.P.J. Abdul Kalam.
• It is the lightest satellite to be ever built and launched into orbit and it is also ISRO's first launch of a satellite built by a private firm.
• It is a communications satellite for ham radio transmission, a form of wireless communication used by amateurs for non-commercial activities.
• The satellite is being built by students belonging to Space Kidz India, a Chennai-based space education firm.
• The satellite costed 1.2 Million Indian rupees and was built during the span of six days.
• The Satellite was launched using the Polar Satellite Launch Vehicle (PSLV), a four-stage rocket.

ISRO attempts reclaiming the Dead Rocket Stage in this launch:

• ISRO made an attempt to recover the dead rocket stage in this launch.
• With PSLV rockets the first three stages usually drop back to Earth; its fourth and final stage using liquid propellants is stopped and restarted several times to get a spacecraft into just the right orbit.
• ISRO converted this fourth stage into an experimental orbital platform to conduct small experiments in space.
• This experimental orbital platform will aid in carrying out experiments in a near zero-gravity environment.
• For the first time, ISRO is conducting such an experiment to reclaim a dead rocket stage and to keep it alive.
