Question 4

Which planet is the primary target of India's Mangalyaan mission launched by ISRO?

Accepted Answer

Mangalyaan, officially known as the Mars Orbiter Mission (MOM), was launched by ISRO in 2013 and reached Mars orbit in 2014. It was designed to study the Martian atmosphere and surface.

Question 5

In which year did ISRO successfully launch the Chandrayaan-1 lunar orbiter mission?

Accepted Answer

Chandrayaan-1 was India's first lunar mission, launched on 22 October 2008. It was an unmanned lunar orbiter that operated successfully and made significant discoveries about the Moon's surface composition.

Question 6

What is the primary function of India's Polar Satellite Launch Vehicle (PSLV) developed by ISRO?

Accepted Answer

PSLV is a four-stage launch vehicle developed by ISRO primarily designed to launch satellites into polar and sun-synchronous orbits. It is one of the most reliable and frequently used launch vehicles by ISRO.

Question 7

Which Indian satellite, launched by ISRO in 1975, was India's first satellite and was named after an ancient Indian astronomer?

Accepted Answer

Aryabhata was India's first satellite, launched on April 19, 1975, using a Soviet Kosmos-3M rocket. It was named after the renowned 5th-century Indian mathematician and astronomer Aryabhata, who made significant contributions to astronomy and mathematics.

Question 8

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 nation to achieve a soft landing on the Moon and the first to land near the south pole.

Question 9

What is the name of ISRO's reusable spacecraft project, which successfully completed its first uncrewed orbital test flight in December 2023?

Accepted Answer

RLV-TD (Reusable Launch Vehicle Technology Demonstrator) is ISRO's project to develop a reusable spacecraft. The RLV-TD completed its first autonomous landing test flight on December 30, 2023, marking a major milestone in India's space technology.

Question 10

Which celestial body is the primary target of ISRO's Aditya-L1 mission, launched in September 2023?

Accepted Answer

Aditya-L1 is ISRO's first dedicated solar observation mission, launched on September 2, 2023. It is positioned at the Sun-Earth Lagrange Point L1 to study the solar corona, solar wind, and solar flares.

Question 11

In which year was the Indian Space Research Organisation (ISRO) established?

Accepted Answer

ISRO was established on August 15, 1969, as India's national space agency. It was formed to develop space technology and conduct space research for national development and scientific advancement.

Question 12

Which Indian space mission successfully demonstrated India's capability to land a spacecraft on the lunar south pole region?

Accepted Answer

Chandrayaan-3 was ISRO's third lunar mission that successfully soft-landed on the Moon's south polar region on 23 August 2023. It comprised a lander and rover (no orbiter). This achievement made India the fourth country to successfully land on the Moon and the first to land near the south pole.

Question 13

Which ISRO spacecraft successfully demonstrated India's capability to soft-land on the lunar south pole region, making India the fourth nation to achieve a soft landing on the Moon?

Accepted Answer

Chandrayaan-3 lander successfully soft-landed near the lunar south pole on 23 August 2023, making India the fourth country (after USSR, USA, and China) to achieve a soft landing on the Moon. This was a major achievement as the south pole region is scientifically significant due to the presence of water ice and permanently shadowed craters.

Question 14

Which ISRO spacecraft successfully demonstrated India's capability to soft-land on the lunar south pole region in August 2023?

Accepted Answer

Chandrayaan-3 lander successfully soft-landed near the lunar south pole on August 23, 2023, making India the fourth nation to achieve a soft landing on the Moon and the first to land near the south pole.

Question 15

In which year did ISRO successfully test the Reusable Launch Vehicle - Technology Demonstrator (RLV-TD), marking a significant step toward developing India's own reusable spacecraft?

Accepted Answer

ISRO conducted the RLV-TD Hypersonic Flight Experiment (HEX) in May 2016, demonstrating autonomous landing and other critical technologies for a future reusable launch system.

Question 16

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

Accepted Answer

Gaganyaan missions are planned to reach a Low Earth Orbit (LEO) altitude of approximately 400 km, similar to the International Space Station's orbit.

Question 17

Which ISRO satellite series is primarily used for Earth observation and resource monitoring, and has been instrumental in disaster management and agricultural planning in India?

Accepted Answer

The Indian Remote Sensing (IRS) satellite series, particularly the Resourcesat and Cartosat variants, are dedicated to Earth observation and have been extensively used for land and water resource management.
