      Past UPSC Prelims PYQs on ISRO Space Missions

      Q1 [2025]: GPS-Aided Geo Augmented Navigation (GAGAN) uses a system of ground stations to provide necessary augmentation. Which of the following statements is/are correct in respect of GAGAN?

      I. It is designed to provide additional accuracy and integrity.
      II. It will allow more uniform and high quality air traffic management.
      III. It will provide benefits only in aviation but not in other modes of transportation.

      Select the correct answer using the code given below.

      (a) I, II and III
      (b) II and III only
      (c) I only
      (d) I and II only

      Correct Answer: (d) I and II only

      Explanation: Statements I and II correctly describe the core purpose and benefit of the GAGAN system. (I) GAGAN is designed to augment GPS signals by correcting for errors, which provides much greater accuracy and guarantees the integrity (reliability) of the positioning information. (II) This enhanced accuracy and reliability directly enables more precise aircraft routing and landing procedures, thus improving the uniformity and quality of air traffic management.

      Q2 [2022]: If a major solar storm (solar flare) reaches the Earth, which of the following are the possible effects on the Earth?

      1. GPS and navigation systems could fail.
      2. Tsunamis could occur at equatorial regions.
      3. Power grids could be damaged.
      4. Intense auroras could occur over much of the Earth.
      5. Forest fires could take place over much of the planet.
      6. Orbits of the satellites could be disturbed.
      7. Shortwave radio communication of the aircraft flying over polar regions could be interrupted.

      Select the correct answer using the code given below:

      (a) 1, 2, 4 and 5 only
      (b) 2, 3, 5, 6 and 7 only
      (c) 1, 3, 4, 6 and 7 only
      (d) 1, 2, 3, 4, 5, 6 and 7

      Answer: The correct answer is (c).

      Explanation: A major solar storm can disrupt GPS, power grids, satellite orbits, polar radio communication, and cause auroras, but cannot trigger tsunamis or forest fires.

      Q3 [2020]: The experiment will employ a trio of spacecraft flying in formation in the shape of an equilateral triangle that has sides one million kilometres long, with lasers shining between the craft.” The experiment in question refers to

      (a) Voyager-2
      (b) New horizons
      (c) Lisa Pathfinder
      (d) Evolved LISA

      Answer: The correct answer is (d) Evolved LISA.

      Explanation: Evolved LISA (Laser Interferometer Space Antenna) is a planned space-based gravitational wave observatory by ESA and NASA, using three spacecraft in a triangular formation with laser beams to detect cosmic gravitational waves.

      Q4 [2016]: Consider the following statements:

      The Mangalyaan launched by ISRO

      1. is also called the Mars Orbiter Mission
      2. made India the second country to have a spacecraft orbit the Mars after USA

      Q5. Consider the following statements about XPosat:
      1. It is the first dedicated satellite from ISRO to carry out research in space-based polarisation measurements of X-ray emission from celestial sources.
      2. It is NASA mission.
      3. XPoSat comprises two payloads POLIX and XSPECT.
      How many of the statements are correct?
      1. Only one
      2. Only two
      3. All three
      4. None
      Answer: Only two
      Solution: X-ray Polarimeter Satellite XpoSat is the first dedicated satellite from ISRO to carry out research in space-based polarisation measurements of X-ray emission from celestial sources. Hence statement 1 is correct and statement 2 is incorrect. It is designed to study X-ray polarization in the medium X-ray band, offering insights into celestial sources radiation mechanisms and geometry. The satellite carries two main payloads, POLIX Polarimeter Instrument in X-rays and XSPECT X-ray Spectroscopy and Timing. Hence statement 3 is correct. POLIX will observe about 40 bright astronomical sources, while XSPECT will study the electromagnetic spectrum generated by different matter.

      Q6. Where did ISRO launch Indias first analog space mission to simulate interplanetary habitat conditions?
      1. Bengaluru, Karnataka
      2. Sriharikota, Andhra Pradesh
      3. Ahmedabad, Gujarat
      4. Leh, Ladakh
      Answer: Leh, Ladakh
      Solution: ISRO launched Indias first analog space mission in Leh, Ladakh, in collaboration with the Human Spaceflight Centre, AAKA Space Studio, University of Ladakh, IIT Delhi, and supported by the Ladakh Autonomous Hill Development Council. The mission aims to simulate conditions similar to those on Mars and the Moon by replicating the extreme challenges astronauts would encounter in extraterrestrial environments. Ladakhs harsh climate, with temperatures ranging from 3 degrees Celsius to 35 degrees Celsius in summer and dropping to -20 degrees Celsius to -35 degrees Celsius in winter, along with heavy snowfall, makes it an ideal analog location. Analog missions, as defined by NASA, are field tests conducted in Earth locations resembling extreme space environments, which help in testing technologies before deploying them in space. This mission will test various technologies like robotic equipment, habitats, communication systems, power generation, mobility, infrastructure, and storage, along with studying behavioral aspects like isolation, confinement, team dynamics, and menu fatigue. Analog missions reduce the need for time, money, and manpower by testing in Earth environments before full-scale space applications. These missions are crucial for planning near-term and future space exploration to destinations like asteroids, Mars, and the Moon, playing a key role in problem-solving and preparing for spaceflight research.

      Q7. What is the primary aim of the European Space Agency's Proba-3 mission, scheduled for launch on December 4, 2024, using ISROs PSLV-XL rocket?
      1. To explore Mars using advanced rover technology
      2. To study the Suns corona by creating an artificial eclipse
      3. To investigate exoplanets using high-precision telescopes
      4. To monitor Earths climate through satellite imaging
      Answer: To study the Suns corona by creating an artificial eclipse
      Solution: Proba-3 mission, a European Space Agency ESA project, aims to study the Suns corona by creating an artificial eclipse in space. The mission will use two small satellites flying in precise formation to act as a single 144-meter-long solar coronagraph. The Coronagraph spacecraft was successfully fueled with hydrazine at Isros Satish Dhawan Space Centre, following stringent safety protocols. Engineers wore Self Contained Atmospheric Protective Ensemble SCAPE suits to safely handle the toxic fuel. The launch is scheduled for December 4, 2024, aboard Isros PSLV-XL rocket. The mission is a technological milestone, demonstrating advanced precision formation flying for satellite operations. Continuous observation of the Suns corona will provide critical data on solar flares and coronal mass ejections, improving understanding of space weather.

      Q8. What is the primary aim of the European Space Agency's ESA Proba-3 mission, which will be launched by ISRO via PSLV-C59?
      1. To study Earths atmospheric changes
      2. To explore the Suns corona
      3. To monitor asteroids near Earth
      4. To test satellite communication technologies
      Answer: To explore the Suns corona
      Solution: ISROs PSLV-C59 will launch the Proba-3 mission for the European Space Agency ESA on December 4, 2024, at 4:08 PM IST from the Satish Dhawan Space Centre SDSC, Sriharikota. Proba-3 features two satellites operating as a unified structure to study the Suns corona, utilizing precision formation flying technology with a 150-meter separation. The satellites will form a solar coronagraph to capture detailed corona views, aiming to improve understanding of solar activity and space weather. The spacecraft will be placed in a highly elliptical orbit 600 km to 60,000 km and test technologies for rendezvous, proximity operations, and control systems.

      Q9. Consider the following statements about the indigenous Green propulsion system that was successfully demonstrated in space on ISROs PSLV-C58 mission:
