Q992. Which of the following is the most appropriate description of Vikram Sarabhai’s vision for the Indian space programme?
Explanation
Vikram Sarabhai’s vision for India was not about competing with advanced nations in a space race or moon landings. Instead, he emphasized the practical application of space technology to solve real-world problems. He prioritized using satellites for mass communication, educational broadcasting, and weather forecasting to benefit the agrarian economy and promote national development for the common citizen.
Q993. Identify the odd one out concerning the technological focus during the early years of India’s space programme under Sarabhai.
Explanation
In the early years, India’s space program focused on atmospheric research using sounding rockets. This included the use of imported Nike-Apache rockets and the development of the indigenous Rohini series. The GSLV Mk III is a modern, high-capacity launch vehicle designed for heavy satellites and human spaceflight, belonging to a much later phase of technological evolution in ISRO’s history.
Q994. Read the following statements and select the correct option:
Assertion (A): Vikram Sarabhai prioritized satellite broadcasting and remote sensing in the early days of the Indian space programme.
Reason (R): He firmly believed that space technology should be utilized for education, agriculture, and national development.
Assertion (A): Vikram Sarabhai prioritized satellite broadcasting and remote sensing in the early days of the Indian space programme.
Reason (R): He firmly believed that space technology should be utilized for education, agriculture, and national development.
Explanation
Vikram Sarabhai championed satellite technology specifically for its potential to transform rural India. He believed that tools like broadcasting and remote sensing were not luxuries but necessities for a developing country. His focus on these areas was rooted in the firm conviction that advanced science should serve national goals like education, improved agriculture, and efficient resource management.
Q995. The Integrated Guided Missile Development Programme (IGMDP), spearheaded by Dr. A.P.J. Abdul Kalam, was formally launched by the Government of India in which year?
Explanation
The Integrated Guided Missile Development Programme (IGMDP) was a strategic initiative launched by the Indian government in 1983. Managed by the Defence Research and Development Organisation, it aimed to achieve self-reliance in missile technology. Dr. A.P.J. Abdul Kalam was appointed as the chief executive, leading the development of several iconic missile systems that form India’s strategic deterrent today.
Q996. Dr. A.P.J. Abdul Kalam strongly advocated the concept of PURA for India’s development. What does PURA stand for?
Explanation
Dr. Kalam advocated for the PURA model to bridge the developmental gap between cities and villages. The concept involves providing four types of connectivity to rural clusters: physical, electronic, knowledge, and economic. By ensuring that rural areas have access to modern infrastructure and opportunities, he believed India could achieve balanced national growth and reduce the migration pressure on urban centers.
Q997. Identify the odd one out among the missiles developed under the original Integrated Guided Missile Development Programme (IGMDP).
Explanation
The original IGMDP included five specific missile projects: Prithvi, Agni, Trishul, Akash, and Nag. These covered various roles from surface-to-surface to anti-tank capabilities. The BrahMos is a supersonic cruise missile developed later through a successful joint venture between India and Russia. While a critical part of the current arsenal, it was not part of the initial 1983 programme.
Q998. Which of the following statements correctly highlights Dr. A.P.J. Abdul Kalam’s contribution to ISRO before he joined DRDO?
Explanation
Before joining DRDO, Dr. Kalam spent two decades at ISRO, where he achieved a major milestone as the Project Director for India’s first Satellite Launch Vehicle. The successful launch of SLV-3 in 1980, which placed the Rohini satellite into orbit, made India a member of the exclusive space club. This achievement demonstrated his leadership in managing complex aerospace projects.
Q999. Consider the following statements regarding Dr. A.P.J. Abdul Kalam:
Statement I: He served as the Chief Project Coordinator for the Pokhran-II nuclear tests in 1998 along with Dr. R. Chidambaram.
Statement II: The successful nuclear tests during this period solidified his public image as the Missile Man of India.
Which of the following is correct?
Statement I: He served as the Chief Project Coordinator for the Pokhran-II nuclear tests in 1998 along with Dr. R. Chidambaram.
Statement II: The successful nuclear tests during this period solidified his public image as the Missile Man of India.
Which of the following is correct?
Explanation
Dr. Kalam played a pivotal role as the Chief Project Coordinator for the 1998 Pokhran-II nuclear tests. Working alongside atomic energy scientists, he ensured the technical success of the mission. The public success of these tests, combined with his leadership in the missile program, firmly established his reputation as the "Missile Man" and a national icon of scientific strength.
Q1000. Which of the following books is an exception and was NOT written or co-authored by Dr. A.P.J. Abdul Kalam?
Explanation
Dr. Kalam was a prolific writer who inspired millions through his books like ‘Wings of Fire’, ‘Ignited Minds’, and ‘India 2020’. These works detailed his life, vision for the country, and the role of youth in development. ‘The Discovery of India’, however, was written by Jawaharlal Nehru while he was imprisoned during the Indian independence movement.Answer key for these questions

Key facts from Science and Technology
- The RPSC paper is General Knowledge and General Science, so science questions come with a strong dose of applied and recent topics.
- Everyday science questions test the laws and terms of physics, chemistry and biology through examples.
- Defence and space questions pair a missile, satellite or mission with its year and organisation.
- Policy questions ask for the year, the body and the aim of schemes like STIP, the National Quantum Mission and BioE3.
- Health, environment and agriculture are on a separate page, with their own chapters.
