INS Viraat is a Centaur class aircraft carrier currently in service with the Indian Navy. INS Viraat is the flagship of the Indian Navy, the oldest carrier in service and one of two aircraft carriers based in the Indian Ocean Region. Viraat is currently the second largest ship in the Indian Navy after the INS Jyoti. Viraat was completed and commissioned in 1959 as the Royal Navy’s HMS Hermes and was transferred to India in 1987.

The Government of India launched the Integrated Guided Missile Development Program in 1983 to achieve self sufficiency in the development and production of wide range of Ballistic Missiles, Surface to Air Missiles etc. Prithvi was the first missile to be developed under the Program. DRDO attempted to build Surface-to-air Missile under Project Devil. The Prithvi missile project encompassed developing 3 variants for use by the Indian Army, Indian Air Force and the Indian Navy. Over the years these specifications underwent a number of changes. While the codename Prithvi stands for any missile inducted by India into its armed forces in this category, the later developmental versions are codenamed as Prithvi II and Prithvi III. Prithvi I class was a surface-tosurface missile having a maximum warhead mounting capability of 1,000 kg, with a range of 150 km. It has an accuracy of 10 – 50 metres and can be launched from Transporter erector launchers. This class of Prithvi missile was inducted into the Indian Army in 1994.

The Supernova is a stellar explosion that is more energetic than a nova. The explosion expels much or all of a star’s material. Supernovae can be triggered in one of two ways: by the sudden re-ignition of nuclear fusion in a degenerate star; or by the collapse of the core of a massive star. The core of an aging massive star may undergo sudden gravitational collapse, releasing gravitational potential energy that can create a supernova explosion. Alternatively a white dwarf star may accumulate sufficient material from a stellar companion (either through accretion or via a merger) to raise its core temperature enough to ignite carbon fusion, at which point it undergoes runaway nuclear fusion, completely disrupting it.

Garden Reach Shipbuilders & Engineers Limited (GRSE) is one of India’s leading shipyards, located in Kolkata, West Bengal. It builds and repairs commercial and navals vessels. Founded in 1884 as a small privately-owned company on the eastern bank of the Hooghly River, it was renamed as Garden Reach Workshop in 1916. The company was nationalized by the Government of India in 1960. It was awarded the Miniratna status, with accompanying financial and operational autonomy in September 2006. Among commercial and scientific ships, GRSE builds oceanographic and hydrographic research vessels, marine acoustic research ships, non-propelled dredgers, grab hopper dredgers, trailing suction hopper dredgers, tugboats, and bulk carriers. GRSE built the Brahmaputra class frigates. It also built two of the Khukri class and all the Kora class corvettes. It has been awarded a contract to build four Kamorta class corvettes. It built all the Seaward class, Trinkat class, Bangaram class, and Car Nicobar class patrol vessels.

The Apollo missions were a series of space missions, both manned and unmanned, flown by NASA between 1961 and 1975. They culminated with a series of manned Moon landings between 1969 and 1972. The first manned flight of Apollo was in 1968 and it succeeded in landing the first humans on Earth’s Moon in 1969 through 1972. It was during the Apollo 11 mission that astronauts Neil Armstrong and Buzz Aldrin landed their Lunar Module (LM) on the Moon on July 20, 1969 and walked on its surface while Michael Collins remained in lunar orbit in the command spacecraft, and all three landed safely on Earth on July 24.
