This Science & Technology quiz on ISRO Launch Vehicles: PSLV, GSLV and LVM3 puts 10 multiple-choice questions to you, the verified MCQs published with GK24's note on the topic. Every question carries a full explanation of why the correct option is right and why the other options are wrong, so you learn the fact behind the answer rather than the letter. Attempt it right after reading the note, keep to the timer, and use the explanations at the end to mark what needs another look. Sit it again before the exam as a quick revision of the topic.
10 questions with answers and explanations
Chandrayaan-3 was placed in orbit by which Indian launch vehicle?
Chandrayaan-3 weighed close to 3,900 kg at lift-off, far beyond the reach of any lighter Indian rocket, so it flew on LVM3, the vehicle earlier named GSLV Mk III.
Read the full explanation →Which was the first Indian launch vehicle to place a satellite in orbit, and which satellite did it carry?
On 18 July 1980 the four-stage, all-solid SLV-3 placed the small Rohini RS-1 satellite in a low earth orbit from Sriharikota, and India became the sixth nation able to launch its own satellite.
Read the full explanation →How many stages does the Polar Satellite Launch Vehicle (PSLV) have?
The PSLV is unusual in alternating propellants between its stages: the first and third stages burn solid propellant and the second and fourth burn liquid propellant.
Read the full explanation →In the GSLV Mk II, which stage is the cryogenic stage?
The GSLV has three stages: a solid core first stage with four liquid strap-on motors, a liquid second stage using a Vikas engine, and a cryogenic upper stage that burns liquid hydrogen with liquid oxygen.
Read the full explanation →Chandrayaan-1 and the Mars Orbiter Mission were both launched by which vehicle?
Chandrayaan-1 went up on PSLV-C11 in October 2008 and the Mars Orbiter Mission on PSLV-C25 in November 2013, both in the extended PSLV-XL configuration with six long strap-on motors.
Read the full explanation →Indian satellites are launched into orbit from which centre?
It is India's only orbital launch site, on the east coast, so vehicles can fly out eastwards over the Bay of Bengal and take the free gain from the earth's rotation while the spent stages fall harmlessly into the sea.
Read the full explanation →On 15 February 2017 the flight PSLV-C37 set an Indian record by placing how many satellites in orbit in a single launch?
PSLV-C37 carried the Cartosat-2 series satellite as its main passenger along with two Indian nano-satellites and 101 small foreign satellites, releasing all of them one after another from its restartable liquid fourth stage.
Read the full explanation →Which ISRO centre is responsible for the design and development of launch vehicles?
Its companion, the Liquid Propulsion Systems Centre, develops the liquid and cryogenic engines that those vehicles fly with.
Read the full explanation →India's indigenously developed cryogenic upper stage flew successfully for the first time on which mission?
That flight carried the GSAT-14 communication satellite and was the first success of the indigenous cryogenic upper stage, which put India among the small group of countries able to build such an engine.
Read the full explanation →Which of the following is ISRO's smallest launch vehicle, designed for launching small satellites on demand?
It has three solid stages and a small liquid velocity trimming module, carries up to about 500 kg to a 500 km low earth orbit, and is designed to be assembled and launched by a small team within days so that a customer with one satellite need not wait for…
