Correct Answer: A. Mangalyaan
The Mars Orbiter Mission, also known as Mangalyaan, was launched in November 2013. It successfully entered the Martian orbit in September 2014. India became the fourth space agency in the world to reach Mars.
Which launch vehicle is famously known as the 'Workhorse of ISRO'?
Correct Answer: C. PSLV
The Polar Satellite Launch Vehicle (PSLV) has a high success rate and has launched numerous Indian and foreign satellites. It was the first Indian launch vehicle to be equipped with liquid stages. PSLV has been used for landmark missions like Chandrayaan-1 and Mangalyaan.
In 2017, ISRO created a world record by launching how many satellites in a single mission?
Correct Answer: D. 104
ISRO's PSLV-C37 mission successfully deployed 104 satellites into orbit simultaneously. Out of these, 101 were foreign satellites and three were Indian. This achievement demonstrated ISRO's advanced capability in multiple satellite deployment.
What is the primary objective of ISRO's Aditya-L1 mission?
Correct Answer: C. Study of the Sun
Aditya-L1 is India's first dedicated scientific mission to study the Sun. The satellite is placed in a halo orbit around the Lagrange point 1 (L1) of the Sun-Earth system. It monitors solar activities and their effect on space weather in real time.
Which Indian lunar mission was the first to discover evidence of water molecules on the Moon's surface?
Correct Answer: A. Chandrayaan-1
Chandrayaan-1 was launched in 2008 and carried the Moon Mineralogy Mapper from NASA. This instrument confirmed the presence of water ice in the polar regions. The mission significantly enhanced our understanding of the lunar chemical composition.
The LVM3 (GSLV Mk-III) rocket is designed to carry heavy satellites into which orbit?
Correct Answer: D. Geosynchronous Transfer Orbit
LVM3 is India's most powerful launch vehicle capable of lifting heavy payloads. It is primarily used to launch satellites into the Geosynchronous Transfer Orbit (GTO). This rocket played a crucial role in the Chandrayaan-3 mission.
What is the name of the human-rated version of the LVM3 rocket being developed for the Gaganyaan mission?
Correct Answer: A. HLVM3
The Human Rated LVM3 (HLVM3) includes safety systems like the Crew Escape System. It is the designated vehicle for India's first manned spaceflight program, Gaganyaan. Various systems are being rigorously tested to ensure the safety of astronauts.
Which ISRO satellite series is primarily dedicated to providing navigation services in India?
Correct Answer: C. NavIC
NavIC (Navigation with Indian Constellation) is an autonomous regional satellite navigation system. It was formerly known as IRNSS and provides accurate position information over India. The system consists of a constellation of seven satellites.
In which year did ISRO successfully execute the Chandrayaan-3 mission, soft-landing on the Moon's South Pole?
Correct Answer: C. 2023
Chandrayaan-3 landed successfully on the lunar surface on August 23, 2023. India became the first country to land a spacecraft near the lunar South Pole. This mission proved India's capability for precise soft landings on celestial bodies.
