[D] 1, 2, 3 & 4
Show Answer
Correct Answer: D [1, 2, 3 & 4]
Notes:- The European Space Agency (ESA)’s Jupiter Icy Moons Explorer (JUICE) is scheduled to launch a rocket carrying a spacecraft destined for Jupiter on April 13, 2023. The spacecraft ‘Jupiter Icy Moons Explorer’(JUICE) is planned to reach Jupiter in 2031. It will spend at least 3 years on Jupiter’s moons after it arrives. It will make detailed observations of Jupiter and its 3 large ocean-bearing moons i.e. Ganymede, Callisto and Europa.
- The Galileo probe, which orbited the gas giant between 1995 and 2003, led to geological discoveries on all four large moons.
- Juno, which has been circling the planet since 2016, has provided unprecedented view into Jupiter’s composition, structure and space environment.

15. Consider the following statements:
- Selk crater is located on Jupiter’s moon Ganymede.
- Ganymede is the second largest moon in our solar system after Saturn’s moon titan.
Which of the statements given above is/are correct?
[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 nor 2
Show Answer
Correct Answer: D [Neither 1 nor 2]
Notes:- NASA’s Dragonfly Mission is a rotorcraft scheduled to reach the Selk Crater region on Saturn’s moon Titan in the year 2034.
- Titan is the Saturn’s largest moon and an icy world whose surface is completely obscured by a golden hazy atmosphere.
- It is the second largest moon in our solar system. Jupiter’s moon Ganymede is largest.
- It is the only moon in the solar system with a dense atmosphere, and it’s the only world besides Earth that has standing bodies of liquid, including rivers, lakes and seas, on its surface.
16. What is the name of NASA’s spacecraft has been studying Jupiter for almost two years since the year 2016?
[A] Muno
[B] Bruno
[C] Juno
[D] Luno
Show Answer
Correct Answer: C [Juno]
Notes:
Juno is a NASA space probe orbiting the planet Jupiter. Launched on 5 August 2011, it entered a polar orbit of Jupiter on 5 July, 2016 to begin a scientific investigation of the planet. Juno’s mission is to measure Jupiter’s composition, gravity field, magnetic field, and polar magnetosphere.
17. Which one of the following is not a Satellite of Jupiter?
[A] Europa
[B] Ganymede
[C] Callisto
[D] Deimos
Show Answer
Correct Answer: D [Deimos]

Callisto, Europa and Ganymede are the satellites of Jupiter. Deimos is a natural satellite of the planet Mars.
18. Consider the following space missions:- GRACE-FO – will explore Mercury’ atmosphere.
- DAVINCI+ will analyse Venus’s atmosphere.
- TRIDENT will explore Jupiter’s moon, Triton.
- PUNCH will study Solar winds from Sun’s outer corona.
Which of the statements given above is/are correct?
[A] Only 1 & 2
[B] Only 2 & 4
[C] Only 2 & 3
[D] Only 1 & 3
Show Answer
Correct Answer: B [Only 2 & 4]
Notes:
The GRACE-FO mission, a collaboration between NASA and the German Research Centre for Geosciences, follows the original GRACE mission (2002-2017) to study Earth’s gravity and climate. DAVINCI+ (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging Plus) will analyze Venus’s atmosphere to explore its formation and potential ocean history. TRIDENT aims to investigate Neptune’s moon Triton to understand habitable world development in the Solar System. PUNCH (Polarimeter to Unify the Corona and Heliosphere) focuses on the transition of particles from the Sun’s corona to the solar wind.
19. Consider the following space missions and their targeted planet for study:
- Cassini – Saturn

[B] Only 1, 2 & 3
[C] Only 1, 2 & 4
[D] 1, 2, 3 & 4
Show Answer
Correct Answer: A [Only 1 & 2 ]
Notes:
The Cassini Mission, a collaboration between NASA and ESA, studied Saturn, its rings, and satellites like Enceladus. The Juno Mission, a NASA probe, entered Jupiter’s orbit as the second spacecraft to do so after Galileo. The proposed MUSE mission by ESA aims to explore Uranus’s atmosphere, interior, magnetosphere, rings, and moons. Akatsuki, known as the Venus Climate Orbiter, is a JAXA probe focused on Venus’s atmosphere.
20. Which of the following is / are moons of Jupiter?
- Ganymede
- Titan
- Enceladus

Select the correct option from the codes given below:
[A] Only 1 & 2
[B] Only 1, 2 & 4
[C] Only 1 & 4
[D] Only 3 & 4
Show Answer
Correct Answer: C [Only 1 & 4 ]
Notes:
Ganymede, Jupiter’s largest moon, is the Solar System’s most massive satellite. Titan, Saturn’s second-largest moon, has a dense atmosphere and stable liquid bodies. Enceladus, also a moon of Saturn, is highly reflective due to its icy surface and contains methane, hydrogen, and water. Europa, another moon of Jupiter, is targeted for study by the JUICE mission and NASA’s Europa Clipper.
