Consider the following statements regarding PSLV (Polar Satellite Lau...
- Both PSLV (Polar Satellite Launch Vehicle) and GSLV (Geosynchronous Satellite Launch Vehicle) are the satellite-launch vehicles (rockets) developed by ISRO. PSLV is designed mainly to deliver the ―earth-observation‖ or ―remote-sensing‖ satellites with a lift-off mass of up to about 1750 Kg to Sun-Synchronous circular polar orbits of 600-900 Km altitude. Hence statement 1 is not correct.
- The remote sensing satellites orbit the earth from pole to pole (at about 98 deg orbital-plane inclination). An orbit is called sun-synchronous when the angle between the line joining the center of the Earth and the satellite and the Sun is constant throughout the orbit. Due to their sun-synchronism nature, these orbits are also referred to as ―Low Earth Orbit (LEO) which enables the on-board camera to take images of the earth under the same sun-illumination conditions during each of the repeated visits, the satellite makes over the same area on the ground thus making the satellite useful for earth resources monitoring. Apart from launching the remote sensing satellites to Sun-synchronous polar orbits, the PSLV is also used to launch the satellites of lower lift-off mass of up to about 1400 Kg to the elliptical Geosynchronous Transfer Orbit (GTO). PSLV is a four-stage launch vehicle with the first and third stages using solid rocket motors and the second and fourth stages using liquid rocket engines. It also uses strap-on motors to augment the thrust provided by the first stage, and depending on the number of these strap-on boosters, the PSLV is classified into various versions like core-alone version (PSLV-CA), PSLV-G, or PSLV-XL variants. Hence statement 2 is not correct.
- The GSLV is designed mainly to deliver the communication satellites to the highly elliptical (typically 250 x 36000 Km) Geosynchronous Transfer Orbit (GTO). The satellite in GTO is further raised to its final destination, viz., Geosynchronous Earth orbit (GEO) of about 36000 Km altitude (and zero deg inclination on the equatorial plane) by firing its in-built on-board engines. Due to their geosynchronous nature, the satellites in these orbits appear to remain permanently fixed in the same position in the sky, as viewed from a particular location on Earth, thus avoiding the need for a tracking ground antenna and hence are useful for the communication applications. GSLV Mk-II has the capability to launch satellites of lift-off mass of up to 2,500 kg to the GTO and satellites of up to 5,000 kg lift-off mass to the LEO. GSLV MK-II is a three-stage vehicle with the first stage using a solid rocket motor, second stage using Liquid fuel, and the third stage, called Cryogenic Upper Stage, using a cryogenic engine. Hence statement 3 is correct.

Consider the following statements regarding PSLV (Polar Satellite Lau...
The correct answer is option 'D', i.e., statement 3 only.
Explanation:
Let's analyze each statement to understand why option D is the correct answer:
1. GSLV is designed primarily to deliver the earth-observation and remote-sensing satellites.
This statement is incorrect. The GSLV (Geosynchronous Satellite Launch Vehicle) is designed to launch satellites into geosynchronous orbit, which is a high Earth orbit. It is primarily used to launch communication satellites, weather satellites, and other similar payloads. The GSLV is capable of launching satellites weighing between 2,500 and 5,000 kilograms.
2. PSLV is a four-stage launch vehicle with the first and second stages using solid rocket motors and the third and fourth stages using liquid rocket engines.
This statement is correct. The PSLV (Polar Satellite Launch Vehicle) is a four-stage launch vehicle developed by the Indian Space Research Organisation (ISRO). The first and second stages of the PSLV use solid rocket motors, while the third and fourth stages use liquid rocket engines. The PSLV is capable of launching payloads weighing up to 1,750 kilograms into the sun-synchronous orbit.
3. GSLV MK-II is a three-stage vehicle with the first stage using a solid rocket motor, the second stage using liquid fuel, and the third stage having a cryogenic engine.
This statement is correct. The GSLV MK-II is a three-stage vehicle developed by ISRO. The first stage of the GSLV MK-II uses a solid rocket motor, the second stage uses liquid fuel (a combination of UDMH and N2O4), and the third stage is equipped with a cryogenic engine. The cryogenic engine uses liquid hydrogen and liquid oxygen as propellants. The GSLV MK-II is capable of launching satellites weighing between 2,500 and 5,000 kilograms into geosynchronous orbit.
Therefore, only statement 3 is correct, and the correct answer is option 'D'.
