Question

Which of the following statements about the GSLV Mk III rocket are correct?

1. It can carry crew modules due to its LEO capabilities.

2. CE-20 is its cryogenic engine.

3. It was first successfully launched in 2001.

• A. 1 and 2 only
• B. 1 and 3 only
• C. 2 and 3 only
• D. All of the above

Answer 1

Answer:

A. 1 and 2 only

• Correct Answer: Option A) 1 and 2 only

• CE-20 is indeed the cryogenic engine used in GSLV Mk III.

• It was first successfully launched in 2014, not 2001.

• The Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III), also known as LVM3, is India's most powerful launch vehicle developed by ISRO. Let's analyze each statement:

• It can carry crew modules due to its LEO capabilities - True. GSLV Mk III has been designed with human spaceflight capabilities in mind. It has sufficient payload capacity to low Earth orbit (LEO) to carry crew modules and is the designated launch vehicle for India's Gaganyaan human spaceflight program.

• CE-20 is its cryogenic engine - True. GSLV Mk III uses the indigenous CE-20 cryogenic engine in its upper stage (C25 stage). This is India's largest cryogenic engine and provides the necessary thrust for placing heavy payloads into orbit.

• It was first successfully launched in 2001 - False. The GSLV Mk III's first developmental flight (GSLV Mk III-D1) took place on June 5, 2017, with the successful launch of GSAT-19 satellite. There was an earlier suborbital test flight in 2014, but the GSLV Mk III program was not even developed in 2001. The regular GSLV program (not Mk III) had its first flight in 2001, which might be the source of confusion.
