  3. It was designed and developed at the Satish Dhawan Space Centre (SDSC) in Kerala's Thiruvananthapuram.

Which of the above statement(s) is/are true?


Event Horizon Telescope (EHT)

Consider the following statements:

  1. Recently, scientists from the Event Horizon Telescope (EHT) facility revealed the first image of the black hole named Sagittarius A* (SgrA*) at the centre of our galaxy, i.e., the Milky Way.
  2. It is a supermassive black hole at the centre of our galaxy, located near the border of the constellations Sagittarius and Scorpius.
  3. SgrA* possesses 1 million times the mass of our sun and is located about 26,000 light-years from Earth.

Which of the above statement(s) is/are true?


National Aeronautics And Space Administration (NASA)

Consider the following statements:

  1. Recently, National Aeronautics and Space Administration (NASA) reported that its InSight Mars lander detected the largest quake ever observed on another planet.
  2. The rover first landed on Mars in November 2020, and has since heard 1,313 quakes.
  3. According to NASA, ‘marsquakes’ are caused due to stresses that cause rock fractures or faults in its crust.

Which of the above statement(s) is/are true?


Cold Atmospheric Pressure Plasma

Consider the following statements:

  1. Recently, a team of Indian researchers has developed a plasma-based disinfectant with the help of cold atmospheric pressure plasma (CAP).
  2. The disinfectant could act as a green decontaminant for COVID-19.
  3. Plasma, the fourth state of matter, makes up most of the universe. When produced in controlled conditions in the lab, it is called as Cold Atmospheric Pressure Plasma (CAP).

Which of the above statement(s) is/are true?


Ultra Violet Imaging Telescope

Consider the following statements:

  1. Recently, scientists from the Indian Institute of Astrophysics, Bengaluru, conducted a study on blue stragglers.
  2. Blue Straggler Stars are hot, blue, massive stars and seem to have a normal trajectory of evolution like other stars.
  3. For the study, the researchers used the UVIT instrument (Ultra Violet Imaging Telescope) of ASTROSAT, India’s first science observatory in space.

Which of the above statement(s) is/are true?


Space Bricks

Consider the following statements:

  1. Recently, researchers from the Indian Space Research Organisation (ISRO) and the Indian Institute of Science (IISc) developed a way to make bricks from Martian soil with the help of bacteria and urea.
  2. These ‘space bricks’ can be used to construct building-like structures on Mars that could facilitate human settlement on the red planet.
  3. The slurry for the space bricks is made by mixing Martian soil with guar gum, a bacterium called Sporosarcina pasteurii, urea and nickel chloride (NiCl2).

Which of the above statement(s) is/are true?


Jupiter’s Moons

Consider the following statements:

  1. Scientists recently said that one of Jupiter’s moons, Europa, a prime candidate for life in the solar system, might have an abundance of water pockets beneath formations called double ridges.
  2. The double ridges found on Europa’s surface are similar to those seen on Earth’s Greenland ice sheet.
  3. Europa is slightly bigger than Earth’s moon.

Which of the above statement(s) is/are true?


Centre For Nano And Soft Matter Sciences (CeNS)

Consider the following statements:

  1. Recently, Indian scientists from the Centre for Nano and Soft Matter Sciences (CeNS) designed an electrocatalyst system for energy-efficient hydrogen production with the help of electrolysis of urea.
  2. The low-cost, earth-abundant Platinum-based catalysts are widely applied for this process.
  3. The energy requirement for production of hydrogen through water electrolysis can be reduced by 70% through urea electrolysis.

Which of the above statement(s) is/are true?


Military Engineering Services (MES)

Consider the following statements:

  1. Recently, Indian Army’s Military Engineering Services (MES) constructed two houses using 3D Rapid Construction Technology.
  2. 3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes.
  3. In an additive process an object is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced cross-section of the object.

Which of the above statement(s) is/are true?


Centre For Development Of Advanced Computing (C-DAC)

Consider the following statements:

  1. Commissioned in May 2020, National Supercomputing Mission (NSM) is jointly led by Department of Science and Technology (DST) and Ministry of Electronics and Information Technology (MeitY).
  2. Recently, the NSM deployed “PARAM Ganga”, a supercomputer at IIT Roorkee, with a supercomputing capacity of 1.66 Petaflops.
  3. The system is designed and commissioned by Centre for Development of Advanced Computing (C-DAC).
