About Space Technology: ISRO Missions, Satellites & Orbits

This quiz is meant for students preparing for the IAS examination and other competitive tests, and for anyone who wants a thorough, well-rounded understanding of India's space technology programme. It begins with ISRO's own institutional history and structure -- its founding, its various constituent centres, and its commercial and regulatory architecture. A second pack covers India's launch vehicle fleet -- from the earliest SLV-3 through the workhorse PSLV, the heavier-lift GSLV family, and newer developments such as the SSLV and reusable launch vehicle technology. A third pack covers orbital regions and India's diverse satellite fleet -- communication, remote sensing and navigation satellites. A fourth pack covers India's lunar and planetary missions -- the three Chandrayaan missions, the Mars Orbiter Mission, Aditya-L1 and the proposed Shukrayaan mission. A fifth pack covers India's human spaceflight programme -- Rakesh Sharma's historic 1984 flight and the more recent, indigenous Gaganyaan programme. It closes with international cooperation and recent developments -- the NISAR mission, space debris management, and the emerging private space sector, and a synthesis tying the whole quiz together. When complete it will have one hundred and twenty-five carefully checked questions, arranged in six packs.

Every question has four options, and the correct option can be in any position. After each question there is a detailed explanation of more than five lines, in simple Indian English that a school student can follow, giving the important names, figures and the points that examiners like to test.

Every fact has been checked against standard reference material on India's space technology programme, current as of this quiz's preparation.
