21. With reference to India's satellite launch vehicle, consider the following statements: [I.A.S. (Pre) 2018]

  1. PSLVs launch the satellites useful for Earth resources monitoring whereas GSLVs are designed mainly to launch communication satellites.
  2. Satellites launched by PSLV appear to remain permanently fixed in the same position in the sky, as viewed from a particular location on Earth.
  3. GSLV Mk III is a four-stage launch vehicle with the first and third stages using solid rocket propellant and the second and fourth stages using liquid rocket engines.

Which of the statements given above is/are correct?

Correct Answer: (a) 1 only
Solution:PSLV (Polar Satellite Launch Vehicle) is an indigenously developed expendable launch system of the ISRO.

It comes in the category of medium-lift launchers with a reach up to various orbits, including the Geo Synchronous Transfer orbit, Lower Earth orbit and Polar Sun Synchronous orbit. GSLV is also operated by ISRO. It is used to launch a satellite into Geo Synchronous Transfer orbit.

The GSLV is designed mainly to deliver the communication satellites to the height of 36000 km. PSLV launches mainly the earth monitoring satellites to the Polar orbits and these satellites do not appear to fix in the same position in the sky.

GSLV Mk III (LVM3) is a three-stage launch vehicle with the first stage using solid propellant, second stage using liquid propellant and the third stage is the cryogenic stage. Hence, only statement 1 is correct.

22. An artificial satellite can be tracked very precisely from the Earth by using: [U.P.P.C.S. (Pre) 2017]

Correct Answer: (a) Doppler effect
Solution:

An artificial satellite can be tracked very precisely from the Earth by using Doppler effect. It is done with the help of tracking transmitter. With the help of doppler effect, this tracking is possible.

23. Which one of the following is not a space satellite? [U.P. Lower Sub. (Spl.) (Pre) 2004]

Correct Answer: (a) SLV-3
Solution:

Rohini is a series of satellites launched by the Indian Space Research Organisation. The Rohini series consists of four satellites, all of which were launched successfully by ISRO. RS-D1 was launched on 31 May, 1981.

IRS satellites is a series of Indian Remote Sensing Satellites for earth's observation. IRS-1D was launched on 29 September, 1997. INSAT-2D satellite was launched on 4 June, 1997. SLV-3 is not a space satellite, it is a satellite launch vehicle which was developed by ISRO.

24. GSLV-D2 which has been recently launched into the orbit is- [U.P.U.D.A/L.D.A. (Pre) 2001]

Correct Answer: (c) Communication Satellite
Solution:

GSLV-D2 carried the GSAT-2 satellite. GSAT-2 was designed and used for communication purposes, including experiments in digital audio broadcasting, internet services, and video broadcasting.

Therefore, the most appropriate answer is (c) Communication Satellite.

25. Consider the following statements:- [I.A.S. (Pre) 2005]

  1. Vigyan Rail is a Science Exhibition on wheels organized by the Council of Scientific and Industrial Research.
  2. Vigyan Prasar is an autonomous body under the Ministry of Human Resources Development.
  3. The educational satellite of ISRO (EDUSAT) was launched in 2004 from French Guiana.

Which of the above statement is correct

Correct Answer: (d) None of the above
Solution:

Vigyan Rail is a science exhibition on the wheels organized jointly by Ministry of Railway and the Department of Science and Technology. It was started on 15 December, 2003 for depicting India’s achievements in various fields of science and technology. Therefore Statement 1 is false.

Vigyan Prasar is an autonomous organization under the Department of Science and Technology not under the Ministry of Human Resources and Development. It was established in the year 1989. So statement 2 is also false.

EDUSAT is the satellite exclusively devoted to meet the demands of the education sector. It was launched on 20 September, 2004 from Satish Dhawan Space Centre, Sriharikota, Andhra Pradesh not from French Guiana. Eventually, the Statement 3 is also false.

26. India became the first country to send Educational Services Satellite in space, Edusat. When was the satellite launched? [U.P.P.S.C. (Mains) 2004]

Correct Answer: (b) 20th September, 2004
Solution:

EDUSAT is the satellite exclusively devoted to meet the demands of the education sector. It was launched on 20 September, 2004 from Satish Dhawan Space Centre, Sriharikota, Andhra Pradesh not from French Guiana.

27. Consider the following statements: [I.A.S. (Pre) 2003]

  1. India launches its first full-fledged meteorological satellite (METSAT) in 2002.
  2. For the first time, the space vehicle PSLV C-4 carried a payload of more than 1000 kg into a geosynchronous orbit.

Which of these statements is/are correct?

Correct Answer: (c) Both 1 and 2
Solution:India’s first full-fledged meteorological satellite was launched on 12 September, 2002. The first time the space vehicle PSLV-C4 has entered into the geosynchronous orbit with having more than 1000 Kg load, also known as METSAT-1. METSAT-1 was renamed Kalpana-1 to honour the late Indian-born astronaut Kalpana Chawla.

28. Kalpana-1 is the new name given to one of the following: [U.P.P.C.S. (Mains) 2004]

Correct Answer: (b) Metsat
Solution:India’s first full-fledged meteorological satellite was launched on 12 September, 2002. The first time the space vehicle PSLV-C4 has entered into the geosynchronous orbit with having more than 1000 Kg load, also known as METSAT-1. METSAT-1 was renamed Kalpana-1 to honour the late Indian-born astronaut Kalpana Chawla.

29. In September 2002, India launched: [U.P.P.C.S. (Pre) 2003]

Correct Answer: (d) METSAT
Solution:India’s first full-fledged meteorological satellite was launched on 12 September, 2002. The first time the space vehicle PSLV-C4 has entered into the geosynchronous orbit with having more than 1000 Kg load, also known as METSAT-1. METSAT-1 was renamed Kalpana-1 to honour the late Indian-born astronaut Kalpana Chawla.

30. Which of the following is Academic Institute Satellite? [M.P.P.C.S. (Pre) 2019]

Correct Answer: (d) SATYABAMASAT
Solution:Sathyabamasat is a micro experimental satellite developed by students and faculty of Sathyabama University, Chennai to collect data on greenhouse gases. It was launched along with the Cartosat-2C satellite atop PSLV-C34 on 22 June, 2016.
