Technology · ISRO मिशन · Questions 61–70 of 70
The Liquid Propulsion Systems Centre (LPSC) of ISRO is located in?
Correct Answer: A. Thiruvananthapuram
LPSC is the lead center for development of liquid propellants and engines. It has facilities in both Valiamala (Thiruvananthapuram) and Mahendragiri. These engines power the core stages of PSLV and GSLV rockets.
Which was the first Indian satellite used for direct TV broadcasting to rural areas?
Correct Answer: A. INSAT-1B
The INSAT-1B satellite, launched in 1983, revolutionized TV broadcasting and telecommunications in India. It enabled the 'SITE' experiment to reach remote villages. It was also vital for improving weather forecasting in the country.
Which state houses the Satish Dhawan Space Centre (SHAR)?
Correct Answer: B. Andhra Pradesh
SDSC SHAR is located on Sriharikota island in Andhra Pradesh. It is the only rocket launch site currently in use by ISRO for major missions. Its location on the east coast is ideal for launching satellites into eastern orbits.
The first Indian experimental satellite, Aryabhata, was launched from which country?
Correct Answer: B. Soviet Union
Aryabhata was launched in 1975 from a Soviet Kapustin Yar launch site. India did not have its own rocket capable of carrying it at that time. The mission was a crucial test of India's ability to build sophisticated spacecraft.
What does the acronym 'GSLV' stand for in ISRO's launch vehicles?
Correct Answer: B. Geosynchronous Satellite Launch Vehicle
GSLV is designed to launch heavy communication satellites into geosynchronous orbits. It uses a cryogenic engine in its third stage for high efficiency. This rocket is essential for India's telecommunication needs.
Which ISRO chairman led the organization during the successful Chandrayaan-3 landing?
Correct Answer: A. S. Somanath
S. Somanath is the current chairman of ISRO and led the team through the historic lunar landing. He is a specialist in rocket engineering and launch vehicles. His leadership has seen several successful missions including Aditya-L1.
The 'NavIC' system is India's own version of which technology?
Correct Answer: B. GPS
NavIC provides accurate regional navigation services over India and surrounding areas. It is independent of the American Global Positioning System (GPS). The system is used for both civilian and strategic defense purposes.
Which center of ISRO is responsible for building satellites?
Correct Answer: B. UR Rao Satellite Centre (URSC)
URSC (formerly ISRO Satellite Centre) is located in Bengaluru and is the hub for satellite design. It has built all of India's major satellites including those for communication and remote sensing. The center is named after the former ISRO chairman U.R. Rao.
The mission 'NISAR' is a joint collaboration between ISRO and which other agency?
Correct Answer: A. NASA
NISAR (NASA-ISRO Synthetic Aperture Radar) is being developed to monitor Earth's changing ecosystems and climate. It will provide extremely detailed radar imagery of the globe. This partnership is one of the largest space collaborations between India and the USA.
In ISRO's mission, what is the meaning of the term 'Cryogenic Stage'?
Correct Answer: B. Uses very low-temperature fuel
A cryogenic stage uses liquid oxygen and liquid hydrogen at extremely cold temperatures. It provides high thrust and is used for heavy-lift missions. Developing this technology indigenously was a very difficult but important success for ISRO.
