The Agni missile is a family of medium to intercontinental range ballistic missiles developed by India, named after one of the five elements of nature. The first missile of the series, Agni-I was developed under the Integrated Guided Missile Development Program and tested 1991. After its success, Agni missile program was separated from the IGMDP upon realizing its strategic importance. As of 2008, the Agni missile family comprises three deployed variants while two more variants are under testing.

The Magellan spacecraft, also referred to as the Venus Radar Mapper, was a 1,035-kilogram (2,280 lb) robotic space probe launched by NASA on May 4, 1989, to map the surface of Venus using Synthetic Aperture Radar and measure the planetary gravity. It was the first interplanetary mission to be launched from the Space Shuttle, the first to use an inertial upper stage booster and was the first spacecraft to test aerobraking as a method for circularizing an orbit. Magellan was the fourth successful, NASA funded mission to Venus and ended an eleven year U.S. interplanetary exploration hiatus.

A comet is a small, icy celestial body that orbits around the sun. It is made up of a nucleus (solid, frozen ice, gas and dust), a gaseous coma (water vapor, CO2, and other gases) and a long tail (made of dust and ionized gases). The tail develops when the comet is near the Sun. The tail can be up to 250 million km long, and is most of what we see. Comets are only visible when they’re near the sun in their highly eccentric orbits.

Dr A.P.J. Abdul Kalam is the undisputed father of India’s missile program. He has breathed life into ballistic missiles like the Agni and Prithvi, which put China and Pakistan well under India’s missile range. It is too exhausting to track Dr Abdul Kalam’s achievements to date. In the ’60s and ’70s he was a trail blazer in the space department. In the ’80s he transformed the moribund Defence Research and Development Laboratory in Hyderabad into a highly motivated team. By the ’90s Kalam emerged as the czar of Indian science and technology and was awarded the Bharat Ratna.

The Polar Satellite Launch Vehicle (PSLV) is an expendable launch system developed and operated by the Indian Space Research Organisation (ISRO). It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into sun synchronous orbits, a service that was, until the advent of the PSLV, commercially viable only from Russia. PSLV can also launch small size satellites into geostationary transfer orbit (GTO). The PSLV has launched 55 satellites / spacecrafts (26 Indian and 29 Foreign Satellites) into a variety of orbits so far.
Note : The Polar Satellite Launch Vehicle, commonly known by its abbreviation PSLV, is an expendable launch system developed and operated by the Indian Space Research Organization (ISRO). On Feb 15, 2017 PSLV-C37 Successfully Launches 104 Satellites in a Single Flight.
