Aircraft carriers in India: An aircraft carrier is considered a key component for a country to project military force away from its shores and provide deterrence. Defensive tasks such as engaging in anti-submarine warfare and providing air defence for the fleet are also central to the functions of an aircraft carrier. Further, the Indian Navy has reached a minimum essential requirement of two operational aircraft carriers to carry out its mandated tasks to ensure maritime security in the Indian Ocean Region. India currently has only one aircraft carrier, INS Vikramaditya which is in service since 2013.

Voyager Probe : The probe is only the second human-built object to leave the bubble of solar particles that emanates from our sun. Voyager 1 departed Earth on 5 September 1977, a few days after its sister spacecraft, Voyager 2. The Voyagers were sent initially to study the outer planets, but then just kept on going. The pair’s primary objective was to survey the planets Jupiter, Saturn, Uranus and Neptune which completed in 1989. Voyager 2 will provide “first-of-its-kind observations of the nature of this gateway into interstellar space. Voyager 2 remains the only craft ever to visit Uranus and Neptune and Voyager second craft to cross the heliopause.

GSAT-7A Satellite: Indian Space Research Organisation (ISRO) successfully launched the communication satellite GSAT-7A on 19th December 2018 from the Satish Dhawan Space Centre (SDSC) in Sriharikota, Andhra Pradesh. GSAT-7A weighing 2250 kg was launched using Geosynchronous Satellite Launch Vehicle (GSLV-F11). ISRO’s GSAT-7A satellite is the heaviest satellite (2250 kgs) with an indigenously developed cryogenic stage that has been launched by GSLV. GSAT-7A is a high-tech communication satellite having new technologies including a Gregorian Antenna. It is the 39th communication satellite of ISRO and will mainly be used for military applications. Indian Air Force’s existing communication capabilities of satellites will be augmented with GSAT-7A
