Daily Current Affairs Quiz: September 19, 2025

Answer: A [1 and 3 only]
Explanation:

Statement 1 is correct: Remote sensing satellites are versatile and used for various applications including weather forecasting, earth observation, and mapping natural resources.

Statement 2 is incorrect: They can capture images not only in the visible spectrum but also in other spectrums.

Statement 3 is correct: The data from these satellites support agricultural monitoring, disaster management, and urban planning.

Statement 4 is incorrect: India’s first remote sensing satellite was not Aryabhata, which was an experimental satellite; instead, India’s first dedicated remote sensing satellite was IRS-1A, launched in 1988.

Answer: B [Only two]
Explanation:

Pair 1 is incorrectly matched: The Mars Orbiter Mission (Mangalyaan) was launched by the Indian Space Research Organisation (ISRO) on November 5, 2013, making it India’s first interplanetary mission to Mars, not NASA.

Pair 2 is correctly matched: The Hope Probe, or the Emirates Mars Mission, was launched by the United Arab Emirates (UAE) on July 19, 2020. It is the UAE’s first mission to Mars and was developed by the Mohammed bin Rashid Space Centre (MBRSC).

Pair 3 is correctly matched: Tianwen-1 is a Chinese Mars mission that includes an orbiter, a lander, and a rover. It was launched by the China National Space Administration (CNSA) on July 23, 2020.

Answer: B [1 and 2 only]
Explanation:

Statement 1 is correct. ISRO and CNES jointly developed the Megha-Tropiques satellite, launched in 2011, to study the water cycle in the tropical atmosphere.

Statement 2 is correct. NISAR, scheduled for launch in 2024, is a joint Earth observation mission between ISRO and NASA.

Statement 3 is incorrect: While JAXA provided some instruments for Chandrayaan-1, the mission was primarily developed and executed by ISRO. Statement 4 is incorrect: While there has been some collaboration between ISRO and Roscosmos on various aspects of the Gaganyaan mission, including astronaut training, the crew module’s primary development rests with ISRO.

Answer: D [2, 3 and 4 only]
Explanation:

Statement 1 is incorrect: Luna 2 was the first spacecraft to reach the Moon’s surface, but it was a hard landing (impact). Luna 9 achieved the first successful soft landing on the Moon.

Statement 2 is correct: Venera 7 was the first spacecraft to successfully land on Venus and transmit data back to Earth.

Statement 3 is correct: Hayabusa, launched by JAXA, successfully returned a sample from the asteroid Itokawa, a significant achievement in space exploration.

Statement 4 is correct: Chang’e 4 made history by achieving the first soft landing on the far side of the Moon, a region previously unexplored in this manner.

Answer: A [1, 2 and 4 only]
Explanation:

Statement 1 is Correct: Chandrayaan-1 (2008) carried NASA’s Moon Mineralogy Mapper (M3), which confirmed the presence of water molecules on the lunar surface — a landmark discovery.

Statement 2 is Correct: Chandrayaan-2 (2019) included an orbiter, lander, and rover. The orbiter continues to function and send data, but the lander (Vikram) failed to soft-land.

Statement 3 is Incorrect: Chandrayaan-2 was India’s first attempt at a soft landing, not Chandrayaan-3. Chandrayaan-3 was the second attempt, learning from the earlier failure.

Statement 4 is Correct: Chandrayaan-3 (2023) successfully achieved a soft landing near the Moon’s south pole, making India the first country to land in this region.
