Answer: Option D. -> Thiruvanananthapuram
Answer: (d)The Vikram Sarabhai Space Centre (VSSC) is located in Thiruvananthapuram. The centre had its beginnings as the Thumba Equatorial Rocket Launching Station (TERLS) in 1962. It was renamed in honor of Dr. Vikram Sarabhai, the father of the Indian space program.

Question 52. Indian Space Research Organization (ISRO) has successfully placed communication satellite GSAT-6 into its intended geosynchronous transfer orbit. Which are the correct information regarding this move?
- It was launched by (GSLV)-D6
- GSLV-D6 is three-stage heavy weight rocket with indigenously made Cryogenic Upper Stage (CUS).
- It is fueled by solid and liquid propellants.
- GSAT-6 is 25th indigenously built geostationary communications satellite
Answer: Option D. -> 1, 2 and 4 only
Answer: (d)It is fueled by liquid Oxygen and liquid Hydrogen propellants. GSAT-6 satellite was carrying S-Band and C-Band transponders meant for public and strategic purposes.

Question 53. Consider the following statements:
- Defence Research and Development Organisation (DRDO) has successfully tested an advanced electronic warfare (EW) suite from Tejas-PV1.
- EW suite consists of Radar Warner and Jammer.
- It will replace existing EW systems, which are fitted on various combat aircraft as they consist of basic equipment – Radar Warner Receiver.
Answer: Option D. -> All of the above
Answer: (d)This suit gives pilot an additional capability of nullifying the effect of detected radar threat by appropriate mode of jamming.

Answer: Option D. -> Apollo
Answer: (d)
Apollo 11 was the spaceflight that landed the first humans, Americans Neil Armstrong and Buzz Aldrin, on the Moon on July 20, 1969. Armstrong became the first to step onto the lunar surface 6 hours later on July 21.
Armstrong spent about two and a half hours outside the spacecraft, Aldrin slightly less; and together they collected 47.5 pounds (21.5 kg) of lunar material for return to Earth.
A third member of the mission, Michael Collins, piloted the command spacecraft alone in lunar orbit until Armstrong and Aldrin returned to it for the trip back to Earth. Launched by a Saturn V rocket from Kennedy Space Center in Merritt Island, Florida on July 16, Apollo 11 was the fifth manned mission of NASA’s Apollo program.

Answer: Option A. -> Negative
Answer: (a)When the missile is launched with a velocity less than the escape velocity, it will be influenced by our gravitation. So it will constitute a bound system for which the total energy (sum of its kinetic energy and potential energy) will be negative.

Question 56. Consider the following statements:
- NASA’s Hubble Space Telescope has spotted massive saltwater ocean under the icy crust of Jupiter’s largest moon Ganymede.
- Ganymede is the largest moon in our solar system.
- It is also the only moon with its own magnetic field.
Answer: Option D. -> All of the above
Answer: (d)Scientists believe that this finding could potentially support life. NASA’s Galileo mission had provided first evidence of ocean in Ganymede after measuring its magnetic field in 2002.

Answer: Option C. -> B-52 Stratofortrees
Answer: (c)
The Boeing B-52 Stratofortress is a long-range, subsonic, jet-powered strategic bomber. The B-52 was designed and built by Boeing, which has continued to provide support and upgrades. It has been operated by the United States Air Force (USAF) since the 1950s. The bomber carries up to 32,000 kg of weapons.
Due to the late 1950s-era threat of surface-to-air missiles (SAMs) that could threaten high-altitude aircraft, seen in the practice in the 1960 U-2 incident, the intended use of B-52 was changed to serve as a low-level penetration bomber during a foreseen attack upon the Soviet Union, as terrain masking provided an effective method of avoiding radar and thus the threat of the SAMs.
Although never intended for the low-level role, the B-52’s flexibility allowed it to outlast several intended successors as the nature of aerial warfare changed.

Answer: Option B. -> 2 and 3 only
Answer: (b)Green diesel is chemically distinct fuel product than biodiesel.
Answer: (b)Green diesel is chemically distinct fuel product than biodiesel.
Answer: Option C. -> Carbon Aerogel
Answer: (c)The world’s lightest substance has been developed by Chinese scientists of Zhejiang University - Carbon aerogel that has a density of only one sixth of that of the air. Its density is only 0.16 mg/cubic centimetre, less than previously recorded lightest substance, graphite aerogel.

Answer: Option D. -> Dakshin Gangotri
Answer: (d)Dakshin Gangotri was the first scientific base station of India situated in Antarctica, part of the Indian Antarctic Program. It is located at a distance of 2,500 kilometres from the South Pole. It was abandoned in 1988-1989 after it was submerged in ice. It was succeeded by the Maitri.
