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.

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.

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.

The HAL Tejas is a lightweight multirole fighter developed by India. It is a tailless, compound deltawing design powered by a single engine. It came from the Light Combat Aircraft (LCA) programme, which began in the 1980s to replace India’s aging MiG-21 fighters. Later, the LCA was officially named “Tejas”, meaning “Radiance” by then Prime Minister Atal Bihari Vajpayee. The Tejas has a pure delta wing configuration, with no tailplanes or foreplanes, and a single dorsal fin. It integrates technologies such as relaxed static stability, fly-by-wire flight control system, advanced digital cockpit, multi-mode radar, integrated digital avionics system, advanced composite material structures and a flat rated engine.

Agni-III is an intermediate-range ballistic missile developed by India as the successor to Agni-II. It has a range of 3,500 km- 5,000 km, and is capable of engaging targets deep inside neighboring countries. The missile’s Circular error probable (CEP) is within 40 meters range, which makes it the most sophisticated and accurate ballistic missile of its range class in the world. Agni III—an intermediate-range ballistic missile—was developed by India as the successor to Agni-II. Designed by the Indian government’s Defence Research and Development Organisation, Agni III is a two-stage ballistic missile that is capable of nuclear weapons delivery. It was designed and developed by the Advanced Systems Laboratory (ASL), a unit of DRDO, which was formed in September 2001 with its main objective being the development of large-sized rocket motors. Note : Agni-VI is an intercontinental ballistic missile reported to be in early stages of development by India. It will be capable of being launched from submarines as well as from land, and will have a strike-range of 8,000–10,000 km with MIRVed warheads. Agni-V is a solid fueled intercontinental ballistic missile (ICBM) developed by Defence Research and Development Organization (DRDO) of India. It will greatly expand India’s reach to strike targets more than 5,500 km away. Agni-IV is the fourth in the Agni series of missiles which was earlier known as Agni II prime. Its full range of 4000 km
