On 15 February 2017 the flight PSLV-C37 set an Indian record by placing how many satellites in orbit in a single launch?
- A.36
- B.68
- C.104
- D.140
Correct answer
Explanation
The correct answer is C, 104. 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. The flight is a standing example of the PSLV's ability to serve as a shared ride for many small payloads.
Option A, 36, is the size of a batch of communication satellites carried on a later commercial LVM3 flight, which is why the number feels familiar. Option B, 68, and option D, 140, match no Indian launch. The point examiners test is the combination of vehicle, date and number, so fix the three together: PSLV-C37, 15 February 2017, 104 satellites, with the Cartosat-2 series satellite as the primary payload.

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.

- 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.

- 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.
