India's remote sensing satellites (like the IRS series and Resourcesat) are used for Earth observation, agriculture monitoring, disaster management, and urban planning. However, they are not designed for direct human transportation or manned spaceflight operations.

Question 7

Which Indian space agency successfully launched the Chandrayaan-3 mission, achieving a soft landing on the lunar south pole in August 2023?

Accepted Answer

ISRO (Indian Space Research Organisation) successfully landed Chandrayaan-3 on the Moon's south polar region on August 23, 2023, making India the fourth country to achieve a soft landing on the Moon and the first to land near the south pole.

Question 8

Which ISRO launch vehicle is primarily used for launching India's heavy satellites and is capable of placing payloads of up to 4 tonnes in Geostationary Transfer Orbit (GTO)?

Accepted Answer

The Geosynchronous Satellite Launch Vehicle (GSLV) is ISRO's heavy-lift launch vehicle designed to place satellites weighing up to 4 tonnes in GTO. The GSLV Mk III variant can carry even heavier payloads and was used for the Chandrayaan-2 and Chandrayaan-3 missions.

Question 9

ISRO's Aditya-L1 mission, launched in September 2023, is designed to study which celestial body?

Accepted Answer

Aditya-L1, launched on September 2, 2023, is India's first dedicated solar mission. It is positioned at the Sun-Earth Lagrange Point 1 (L1) to study the Sun's corona, solar winds, and solar flares without any obstruction from Earth's atmosphere.

Question 10

India's first indigenous satellite 'Aryabhata' was launched in which year?

Accepted Answer

Aryabhata, India's first indigenous satellite, was launched on April 19, 1975, from the Baikonur Cosmodrome in the Soviet Union. It was named after the ancient Indian mathematician and astronomer Aryabhata.

Question 11

India's Mars Orbiter Mission (Mangalyaan) was launched in which year, making India the first country to reach Mars in its first attempt?

Accepted Answer

Mangalyaan was launched on November 5, 2013, and successfully entered Mars orbit on September 24, 2014. India became the first country to reach Mars in its maiden attempt and the first non-Western nation to reach Mars orbit.

Question 12

Which Indian space mission successfully demonstrated India's capability to soft-land on the Moon and deploy a rover on its surface?

Accepted Answer

Chandrayaan-3 was India's third lunar mission, launched by ISRO in July 2023. It successfully soft-landed on the Moon's south polar region on 23 August 2023 and deployed the Pragyan rover, making India the fourth country to achieve a soft landing on the Moon and the first to land near the lunar south pole.

Question 13

The Gaganyaan programme aims to send Indian astronauts to space. What is the planned orbital altitude for the crewed missions?

Accepted Answer

ISRO's Gaganyaan programme plans to send Indian astronauts to a Low Earth Orbit (LEO) at approximately 400 km altitude, similar to the International Space Station's orbit. This altitude was selected to balance fuel efficiency, radiation exposure, and mission safety.

Question 14

ISRO's Pushpak spaceplane project aims to develop a reusable spacecraft. Which Indian space centre is leading this project?

Accepted Answer

The Pushpak spaceplane project is being developed by ISRO's Vikram Sarabhai Space Centre (VSSC) in Thiruvananthapuram, Kerala. Pushpak is designed as a reusable, winged spacecraft that will be launched atop a launch vehicle and land autonomously like an aircraft. The project aims to reduce space access costs through reusability, similar to SpaceX's Falcon 9 first stage.

Question 15

Which Indian space mission successfully demonstrated India's capability to soft-land on the lunar south pole region, making India the fourth country to achieve a soft landing on the Moon?

Accepted Answer

Chandrayaan-3 successfully soft-landed near the lunar south pole on 23 August 2023, with the lander and rover operating as planned. This made India the fourth nation (after USSR, USA, and China) to achieve a soft landing on the Moon, and the first to land near the south pole region.

Question 16

The Chandrayaan-3 mission successfully soft-landed on the Moon in August 2023. On which lunar region did it land?

Accepted Answer

Chandrayaan-3 successfully soft-landed on the Moon's south polar region on August 23, 2023. The lander touched down near the Manzinus C crater, making India the fourth nation to achieve a soft landing on the Moon and the first to land near the lunar south pole. This region is of high scientific interest due to the presence of water ice in permanently shadowed craters.

Question 17

Which ISRO satellite mission was designed to study the Sun's corona and outer atmosphere, and was launched in September 2023?

Accepted Answer

Aditya-L1 is ISRO's first dedicated solar mission, launched on September 2, 2023, from Sriharikota. It is positioned at the Sun-Earth L1 Lagrange point (approximately 1.5 million km from Earth) to observe the solar corona, chromosphere, and photosphere without any obstruction from Earth's magnetic field.

Question 18
