Chandrayaan-1 and the Mars Orbiter Mission were both launched by which vehicle?
- A.GSLV Mk III
- B.PSLV
- C.SLV-3
- D.GSLV Mk II
Correct answer
Explanation
The correct answer is B, the PSLV. 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. Both spacecraft were light enough for the PSLV to place them in a high ellipse from which their own engines raised them towards the moon and Mars.
Option A, GSLV Mk III, now called LVM3, was not yet operational in 2008 and was used later for Chandrayaan-2 and Chandrayaan-3. Option C, SLV-3, could lift only about 40 kg and was retired in the early 1980s. Option D, GSLV Mk II, is meant for communication satellites bound for geostationary orbit and was not used for either interplanetary mission. This pairing of vehicle with mission is the single most asked point in the chapter.

Practice Questions
View allChandrayaan-3 was placed in orbit by which Indian launch vehicle?
- A.PSLV-XL
- B.GSLV Mk II
- C.LVM3
- D.SSLV
Show answer
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.

- A.ASLV, carrying SROSS-C
- B.SLV-3, carrying Rohini RS-1
- C.PSLV, carrying IRS-1A
- D.SLV-3, carrying Aryabhata
Show answer
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?
- A.Two
- B.Three
- C.Four
- D.Five
Show answer
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?
- A.First stage
- B.Second stage
- C.Third stage
- D.Fourth stage
Show answer
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.

- A.Vikram Sarabhai Space Centre, Thiruvananthapuram
- B.Satish Dhawan Space Centre, Sriharikota
- C.U R Rao Satellite Centre, Bengaluru
- D.Space Applications Centre, Ahmedabad
Show answer
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.
