11. What is the geostatic position? [U.P.P.C.S. (Mains) 2005]

Correct Answer: (c) When the object moves around the Earth with the velocity commensurate with the velocity of the Earth such that it maintains a fixed position in relation to some place on the Earth.
Solution:When the object moves around the Earth with the velocity commensurate with the velocity of the Earth such that it maintains a fixed position (fixed height) in relation to some place on the Earth, it is called geostatic position. All the geostationary satellites work on the same principle.

12. Geo-stationary satellite revolves at : [Chhattisgarh P.C.S. (Pre) 2018]

Correct Answer: (b) A fixed height
Solution:When the object moves around the Earth with the velocity commensurate with the velocity of the Earth such that it maintains a fixed position (fixed height) in relation to some place on the Earth, it is called geostatic position. All the geostationary satellites work on the same principle.

13. In which atmospheric layer, the communication satellites are located? [U.P.P.C.S. (Mains) 2004]

Correct Answer: (d) Exosphere
Solution:The exosphere is the outermost layer of Earth’s atmosphere. Air in the Exosphere is extremely thin in many ways. It is almost the same as the airless void of outer space and in this, the communication satellites are located.

14. A geostationary satellite has a period of: [U.P.P.C.S. (Mains) 2010]

Correct Answer: (d) 24 hours
Solution:The geostationary satellite has the same orbital period as the earth's rotation period i.e. 24 hours.

15. The time period of revolution of a geostationary satellite is : [U.P.R.O/A.R.O.(Mains) 2016, Uttarakhand P.C.S.(Pre) 2016]

Correct Answer: (b) 24 hours
Solution:The geostationary satellite has the same orbital period as the earth's rotation period i.e. 24 hours.

16. Which of the following diagrams represents the most accurate path of a geostationary satellite in space? [I.A.S. (Pre) 1993]

Correct Answer: (a)
Solution:Geostationary satellite has a circular path. Therefore option (a) represents the most accurate path of the geostationary satellite in space.

17. NASA-U.S. space agency, has launched a telescope named Kepler to find: [U.P.P.C.S. (Mains) 2016]

Correct Answer: (d) Earth-like planets
Solution:Kepler was a space telescope launched by NASA to discover Earth-like planets orbiting other stars. It was launched in 2009. The initial planned lifetime for this was 3.5 years but it was expanded.

After 9 years of operation, NASA announced its retirement on 30 October, 2018. Kepler discovered more than 2600 "exoplanets" including many that are promising places for life to exist.

18. Who is the scientist in whose honour the "Chandra X-ray telescope" has been named? [I.A.S. (Pre) 2001]

Correct Answer: (d) Subramanyan Chandrasekhar
Solution:Chandra X-ray telescope is a space observatory launched by Columbia Space Shuttle on 23 July, 1999. The telescope is named after the Indian American-Astrophysicist Subrahmanyan Chandrasekhar.

19. Match List-I with List-II and select the correct answer by using the codes given below the lists: [U.P.P.C.S. (Pre) 2013 , U.P.D.A/L.D.A. (Pre) 2013]

List-IList-II
A. Curiosity Rover1. Tablet
B. Messenger2. Unmanned Aerial vehicle of DRDO
C. Rustam-13. Mars probe space vehicle of U.S.A.
D. Akash-24. Mercury probe space vehicle of NASA

Code :

CODEABCD
(a)3421
(b)4312
(c)4321
(d)1234
Correct Answer: (a) 3 4 2 1
Solution:Curiosity: Curiosity is a car-sized robotic rover exploring Gale Crater on Mars as part of NASA’s Mars Science Laboratory mission. It was launched from Cape Canaveral on 26 November, 2011.
  • Messenger: Messenger was a robotic NASA spacecraft launched in August, 2004 to study Mercury's chemical composition, geology, and magnetic field.
  • Rustam-1: Rustom is a medium Altitude Long Endurance unmanned combat air vehicle being developed by the Defence Research and Development Organization (DRDO).
  • Akash-II: The new version of the world's cheapest tablet.

20. Which one of the following is NASA’s last Space Shuttle? [U.P. Lower Sub. (Pre) 2009]

Correct Answer: (a) Atlantis
Solution:Atlantis was the last and final space shuttle of NASA. It was launched on 8 July, 2011 and landed on 21 July, 2011. Columbia space shuttle was disintegrated during re-entry in Earth's atmosphere on 1 February, 2003.

The last Mission of Discovery space shuttle was held between 24 February to 9 March, 2011. On 16 May, 2011 the Endeavor was launched for its last space mission and it successfully landed on Earth on 1 June, 2011.
