According to Dr Jitendra Singh, what is the projected size of India's space economy in the coming decade?

  1. A.USD 15-20 billion
  2. B.USD 25-30 billion
  3. C.USD 40-45 billion
  4. D.USD 70-75 billion

Correct answer

C. USD 40-45 billion

Explanation

The correct answer is USD 40-45 billion. The Minister said India's space economy has grown to nearly USD 9 billion and is projected to reach USD 40-45 billion in the coming decade. In the same breath he noted that the country's space startup ecosystem has expanded from a single-digit number to nearly 450 enterprises, a change he credited to the space sector reforms of the past five to six years and to the creation of NewSpace India Limited and IN-SPACe. Options A and B understate the projection and match no figure in the announcement; the only smaller number quoted is the present size of the space economy, which is close to USD 9 billion. Option D overstates it and does not appear anywhere. For the examination hall, pair the two economy figures together, the present value and the projected band, and keep the startup count beside them, since question setters often ask for all three in one go.

Data from which space mission enabled the discovery that UBC 63 is a double cluster system?

  1. A.Hubble Space Telescope of NASA
  2. B.Gaia mission of the European Space Agency
  3. C.AstroSat of ISRO
  4. D.James Webb Space Telescope
Show answer
Correct answer: B. Gaia mission of the European Space Agency

The researchers used Gaia measurements, which give exceptionally precise positions and motions for stars right across the Milky Way, and it was these data that revealed two populations of starkly different ages inside what had been taken for one cluster.

What are the approximate ages of UBC 63A and UBC 63B?

  1. A.21 million years and 562 million years
  2. B.562 million years and 21 million years
  3. C.100 million years and 400 million years
  4. D.6 million years and 26 million years
Show answer
Correct answer: A. 21 million years and 562 million years

UBC 63A is the young cluster of the pair at roughly twenty-one million years, while UBC 63B is much older at about five hundred sixty-two million years.

What did a team led by Indian astronomers find about the galactic open cluster UBC 63?

  1. A.It is the nearest open cluster to the Sun
  2. B.It is actually two distinct clusters that passed close to each other
  3. C.It hosts the first planet found outside the Milky Way
  4. D.It is merging with the Andromeda galaxy
Show answer
Correct answer: B. It is actually two distinct clusters that passed close to each other

The group, which lies about 4892 light years away and had been treated in the limited earlier literature as a single cluster, was found to hold two separate stellar populations, now named UBC 63A and UBC 63B. Their brightness and colours formed two sequences in the colour magnitude diagram, and…
