1. Which of the following statements are true?
1. HysIS is an earth observation satellite built around ISRO’s Mini Satellite-2 (IMS-2) bus.
2. It was placed into polar sun synchronous orbit and has mission lifespan of 5 years
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Ans: c
Justification:
-
HysIS is an earth observation satellite built around ISRO’s Mini Satellite-2 (IMS-2) bus. It was placed into polar sun synchronous orbit and has mission lifespan of 5 years.
-
Hyperspectral Imaging Technology combines the power of digital imaging and spectroscopy to attain both spatial and spectral information from an object.
-
This result can be then used to identify, measure and locate different materials and their chemical and physical properties.
2. Copernicus Programme is associated with
(a) Earth Observation
(b) Deep sea Exploration
(c) Neutrinos
(d) Gravitational waves
Ans: a
Justification:
-
Copernicus Programme is Earth observation programme headed by the European Commission (EC) in partnership with the European Space Agency (ESA).
-
India will get free, full and open access to the data from the Copernicus Sentinel family of six satellites.
3. Which of the following statement/s is/are true?
1. The neutrinos are the most abound particles in the universe
2. They carry no electrical charge and are nearly mass-less.
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Ans: b
Justification:
-
The neutrinos are second most abound particles in the universe. They interact very little with anything and pass through everything that’s why it’s hard to detect them.
-
They carry no electrical charge and are nearly massless. They occur in 3 different types, separated based on mass (electron-neutrino, muon-neutrino, tauneutrino).
-
They are produced in the core of the sun & millions of them roam around in the solar system.
4. Which of the following statement/s is/are true?
1. Gravitational waves are distortions or ‘ripples’ in the fabric of spacetime
2. Albert Einstein predicted the existence of gravitational waves in 1916 in his general theory of relativity.
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Ans: c
Justification:
-
Gravitational waves are distortions or ‘ripples’ in the fabric of spacetime caused by some of the most violent and energetic processes in the Universe such as such as the explosion of giant stars, the collision of neutron stars, and the coming together of black holes.
-
Albert Einstein predicted the existence of gravitational waves in 1916 in his general theory of relativity.
5. GROWTH Initiative is associated with
(a) Astronomy
(b) Gastronomy
(c) Palaeontology
(d) Pedology
Ans: a
Justification:
-
GROWTH-India is a joint project of Indian Institute of Astrophysics, Bangalore and the Indian Institute of Technology Bombay (IITB).
-
India’s first robotic telescope – Global Relay of Observatories Watching Transients Happen (GROWTH)-India, began its operation at the Indian Astronomical Observatory (IAO) in Hanle in Ladakh.
-
GROWTH Initiative is a part of multi-country collaborative initiative to observe transient events in the universe
