Practice Questions
Q1. Which launch vehicle was used by ISRO for the successful deployment of EOS-07 and its co-passenger payloads?
- Geosynchronous Satellite Launch Vehicle (GSLV-MkIII)
- Small Satellite Launch Vehicle (SSLV)
- Polar Satellite Launch Vehicle (PSLV-C58)
- Reusable Launch Vehicle (RLV-TD)
Explanation: The article explicitly states that EOS-07 was launched aboard the Polar Satellite Launch Vehicle (PSLV-C58). The PSLV is ISRO's workhorse rocket, known for its reliability in launching Earth observation and remote sensing satellites into polar orbits.
Q2. What is the approximate spatial resolution of the Panchromatic and Multispectral Imager (PMI) on board EOS-07?
- 5 meters
- 2.5 meters
- 1 meter
- 0.5 meters
Explanation: EOS-07 is equipped with a state-of-the-art Panchromatic and Multispectral Imager (PMI) capable of providing imagery with a spatial resolution of 0.5 meters. This high resolution allows for very detailed observation of the Earth's surface.
Q3. Which of the following sensors on EOS-07 provides all-weather, day-and-night imaging capabilities?
- Panchromatic and Multispectral Imager (PMI)
- Thermal Infrared Sensor (TIRS)
- Synthetic Aperture Radar (SAR)
- Visible and Near Infrared Radiometer (VNIR)
Explanation: The Synthetic Aperture Radar (SAR) sensor is crucial for its ability to penetrate clouds and operate effectively during both day and night. This makes it invaluable for continuous monitoring, especially during adverse weather conditions or natural disasters, unlike optical sensors which are limited by cloud cover and daylight.
Q4. What is the primary role of NewSpace India Limited (NSIL) in ISRO's operations?
- To conduct scientific research and planetary missions.
- To develop new launch vehicle technologies for ISRO.
- To act as the commercial arm of ISRO for marketing space products and launch services.
- To train astronauts for human spaceflight missions.
Explanation: NewSpace India Limited (NSIL) is the commercial arm of ISRO. Its primary role is to market ISRO's space products and services, including launch services for external customers and technology transfer to Indian industries, thereby boosting India's presence in the global space economy.
Q5. When was the Indian Space Research Organisation (ISRO) officially established?
- 1962
- 1969
- 1975
- 1988
Explanation: The Indian Space Research Organisation (ISRO) was officially established in 1969, evolving from the Indian National Committee for Space Research (INCOSPAR) which was formed in 1962. Aryabhata, India's first satellite, was launched in 1975.
How to Prepare Science & Technology for Government Exams
For Railway exams, make flashcards for every major ISRO launch — name, payload, purpose, date. These repeat frequently.
For SSC, focus on defence acquisitions and their strategic significance rather than technical specs.
For UPSC, connect every scientific development to policy — climate targets, digital India, health policy.
