As the first man to escape Earth’s gravitation field and achieve orbit, Yuri Gagarin holds the title of first human being in space. On 12 April, 1961 in his craft Vostok 1, Gagarin completed a single orbit of the Earth. Performed at an altitude of 187 3/4 miles (302 kilometers), the orbital rotation took 108 minutes at 18,000 miles an hour. For this he was nominated a Hero of the Soviet Union.

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.

Himadri Station is India’s first Arctic research station located at Spitsbergen, Svalbard, Norway. It is located at the International Arctic Research base, Ny-Ålesund. The station is operated by National Centre for Antarctic and Ocean Research. The station was inaugurated in 2008 by Kapil Sibal, Minister for Science & Technology. Note : Himadri Station is India’s first Arctic research station located at Spitsbergen, Svalbard, Norway. It is located at the International Arctic Research base, Ny-Ålesund. At Arctic, meteorological, biological, glaciological and past climate studies are undertaken in the vicinity of the station ‘Himadri’. Local boats are hired for marine research. India presently has two research stations at Antarctica namely ‘Maitri’ and ‘Bharati’. New station ‘Bharati’ has just been constructed and established in March, 2013. At both the stations, research and investigations are undertaken to understand the Polar processes and phenomenon. Observations and studies are carried out in atmospheric, biological, geological, ecological sciences etc. Maitri station has been in operation since 1989. Dakshin Gangotri was the first scientific base station of India situated in Antarctica, part of the Indian Antarctic Program. It is currently being used as a supply base and transit camp.

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.

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.
