First Satellite Launched by India
Aryabhatta was the first satellite launched by India. It was named after the great Indian astronomer of the same name. Aryabhatta weighed 360kg and was launched by the Soviet Union on April 19, 1975 from Kapustin Yar using a Cosmos-3M launch vehicle.
The satellite had following objectives:
1. To indigenously design and fabricate a space-worthy satellite system and evaluate its perfromance in orbit.
2. To evolve the methodology of conducting a series of complex operations on the satellite in its orbital phase.
3. To set up ground-based receiving, transmitting and tracking systems.
4. To establish infrastructure for the fabrication of spacecraft systems.
Aryabhatta carried experiments related to X-Ray Astronomy, Solar Physics and Aeronomy. The satellite re-entered the Earth's atmosphere on 11 February 1992.

Tarapur Atomic Power Station (T.AP.S.) was the first nuclear power plant in India. The construction of the plant was started in 1962 and the plant went operational in 1969. The 320 MW Tarapur nuclear power station housed two 160 MW boiling water reactors (BWRs), the first in Asia. The Tarapur Plant was originally constructed by the American companies Bechtel and GE, under a 1963 123 Agreement between India, the United States, and the IAEA. The Tarapur Atomic Power Station is under the control of Nuclear Power Corporation of India Limited. Recently, two 540 MW pressurised heavy water reactors (PHWRs) were operationalised at Tarapur. The new reactors were constructed by L & T and Gammon India. Tarapur Nuclear Power Station is the largest PHWR-based power station in India.
Sir Chandrasekhara Venkata Raman (C.V. Raman) was the first Indian scientist to win Nobel Prize. C.V. Raman was awarded the 1930 Nobel Prize in Physics for his work on the scattering of light and for the discovery of the Raman effect, which is named after him. Raman effect relates to the inelastic scattering of a photon. When light is scattered from an atom or molecule, most photons are elastically scattered (Rayleigh scattering). The scattered photons have the same energy (frequency) and, therefore, wavelength, as the incident photons. However, a small fraction of scattered light (approximately 1 in 10 million photons) is scattered from excitations with optical frequencies different from, and usually lower than, the frequency of the incident photons. Raman effect is helpful in analyzing the composition of liquids, gases, and solids.
The Zoological Garden in Kolkata is the largest Zoo in India. It is spread over an area of about 100 acres. The Zoo is located on Belvedre road in Kolkata and was established in 1876. The zoo is home to a rich variety of birds, animals, and reptiles.
The origins of the Zoo can be traced back to 1873, when, the then Governor Sir Richard Temple proposed the formation of a zoo in Calcutta. Sir C.L. Lendal corroborated it. Finally, the Government allotted land for this purpose responding to the joint petition of the Asiatic Society and Agri-Horticultural Society. The zoo was inaugurated on the January 1, 1876 by King Edward VII.
Zoological Garden, Kolkata is credited with bringing back the rare Manipur Brow Antlered Deer from near extinction. The zoo was first to have bred Giraffes and has produced Tigions, and Litigons as a cross breeding experiment. The artificial lake of the zoo attracts a large number of migratory birds every year.
