Inter–University Accelarator Centre (IUAC) is an autonomous research facility of University Grants Commission which is based in New Delhi. Vikram Sarabhai Space Centre (VSSC) is a major space research centre of the Indian Space Research Organisation, focusing on rocket and space vehicles, is located in Thiruvananthapuram, Kerala.

Arihant is a class of nuclear–powered ballistic missile submarine. AWACS, abbreviation of Airborne Warning and Control System, is a mobile, long–range surveillance and control centre for air defence, developed by the U.S. Air Force, is mounted on Boeing 707 aircraft. Atlas – Centaur is an American expendable launch system. It is the first production rocket stage to use cryogenic propellent. Nag is a third generation fire–and–forget" anti-tank missile of India.

Space based solar power (SBSP) is considered to be made a national goal, because its supply is 99% uninterrupted throughout the year, besides the enormity of energy availability.

A 'Gravity tractor' (GT) is a spacecraft with a mechanism that can deflect another object in space without physically contacting it. It will use only its gravitational field to transmit the required impulse. It can effect a potentially hazardous asteroid that might hit earth.

The main objectives of the New Science and Technology Policy are optimal utilisation of existing physical and knowledge resources, development of innovative technologies and management of intellectual property.

An orbiting satellite is a projectile, that the only force acting upon an orbiting satellite is the force of gravity. The force of gravity also accelerates it towards the earth. But the earth's round shape prevents it from falling on ground and if the satellite is at more than 8000 m/s speed it also contributes to the maintenance of motion in a particular orbit or elliptical path.

Multiple Independent Re–entry Vehicle (MIRV) is a ballistic missile payload or "bus" of a ballistic missile. It is capable of being aimed to hit one of a group of targets. A unitary warhead is a single warhead on a single missile Multiple re-entry vehicle (MRV) is an intermediate case in which the MRV missile carries several reentry vehicles, which can be dispersed but not individually aimed.

The Intelligent Flight Control System (IFCS) is a next–generation flight control system designed to provide increased safety for the crew and passengers. It was developed by NASA and IFCS tested it in NF–15B. Generation 1 IFCS flight tests conducted in 2003.

Both the statements regarding Indian Polar Research stations are incorrect. India's first expedition to Antarctica was in 1981, it expanded by undertaking its first Arctic expedition in August 2007 by setting up 'Himadri' at Nye–Alesund in Norway in 2008 to mark the International Polar Year (IPY). The first Antarctic research station was Gangotri (1983) and second was Maitri (1989). 'Bharti' or 'Bharthi' is the third Antarctic station at Larsemann in East Antarctica.

ISRO and NASA have agreed to form a working group for co-operation in Moon and Mars mission for future metrology and space exploration and also in Helio physics.

'Curiosity' is a car–sized robotic rover, exploring Gale Crater on Mars as part of NASA's Mars Science Laboratory Mission (MSL) 'MESSENGER' is an acronym of Mercury Surface Environment, Geochemistry, and Ranging. It is a robotic NASA spacecraft orbiting the planet Mercury. Rustom is a medium Altitude Long Endur-ance unmanned combat air vehicle (UCAV) being developed by DRDO. Akash–2 is a computer Tablet developed by DATAWIND an Indian company.

A computer keyboard, a typewriter–style device having a particular arrangement of buttons or keys, is a main input device. It inputs text, numbers and sends commands to the computer.

Akash is a medium–range mobile surface–to– air missile. Nag is an antitank missile by DRDO. Pinaka is a multiple rocket launcher produced for Indian Army by DRDO while Trishul is a missile system of a short range surface to–air missile as a part of the Integrated Guided Missile Development Program.

Radar is a system that uses radio waves for object deflection. It determines the range, altitude, direction, or speed of objects.

INS Tarkash is a Talwar–class multirole stealth frigate constructed by Indian Navy.

The old 2001 policy mandated that ISRO could release only data upto 5.8 meter resolution.

4K TV is an Ultra high definition television. UHDTV, has horizontal resolution on the order of 4,000 pixels. Since its screen is too big the HD gives blurred images.

New Super Wi-Fi will support 802.11 ad standard, it can send data upto the length of 1-2 GB and would function at the speed of 7 gigabits per second

Dark matter is a type of matter hypothesized in astronomy and cosmology to account for a large part of the mass that appears missing from the universe, it does not interact with light. It is also hypothesized that it interacts with ordinary matter through gravity and binds galaxies, and it pushes the universe apart.

‘Greenware’ is completely free of both hazardous PVC and BFR and its manufacturing can be a special action like replacing all standard light bulbs with CFLs or a more general application to live more ecologically.
