APPLE, India's first experimental communication satellite, was launched in 1981 by which launch vehicle?
- A.SLV-3 of India
- B.A Soviet launch vehicle
- C.The European Ariane rocket
- D.A United States Space Shuttle
Correct answer
Explanation
The correct answer is C, the European Ariane rocket. The full name of the satellite, Ariane Passenger Payload Experiment, contains the answer, since it flew as a passenger on an Ariane launch in 1981 to test the building of a geostationary communication satellite in India. India then had no vehicle able to reach a geostationary transfer orbit.
Option A, SLV-3, could place only about 40 kg in a low earth orbit and could never have carried APPLE to the height a communication satellite needs. Option B, a Soviet vehicle, had launched Aryabhata in 1975 and Bhaskara in 1979, so it is a reasonable guess but the wrong one here. Option D, the Space Shuttle, carried the later INSAT-1B in 1983, which is a separate fact often asked alongside. The bullock cart photograph of APPLE at the test site is from this programme.

Practice Questions
View allWhich was India's first satellite and in which year was it launched?
- A.Rohini, 1980
- B.Aryabhata, 1975
- C.Bhaskara-1, 1979
- D.APPLE, 1981
Show answer
It was launched on 19 April 1975 by a Soviet launch vehicle, since India had no vehicle of its own at the time, and it carried experiments in X-ray astronomy, solar physics and the ionosphere.

- A.Navigation with Indian Constellation
- B.National Voyage and Indian Communication
- C.Navigation Indian Coordinates
- D.Navigational Information Centre
Show answer
The name was given in 2016 to the Indian Regional Navigation Satellite System, IRNSS, when the seventh satellite of the constellation was placed in orbit, and the word navik also carries the sense of a sailor or navigator, which is why it was chosen.
Read the full explanation →The NavIC constellation was designed with how many satellites?
- A.Four
- B.Seven
- C.Nine
- D.Twenty-four
Show answer
The system was designed as a constellation of seven satellites, three of them in geostationary orbit and four in geosynchronous orbits inclined to the equatorial plane, a small number being enough because the service area is regional and not global.

- A.INSAT-1B
- B.Kalpana-1
- C.Bhaskara-2
- D.Oceansat-1
Show answer
Launched in 2002 as METSAT, it was the first Indian satellite built only for weather work, and it was renamed Kalpana-1 in memory of Kalpana Chawla, the India-born astronaut who died in the Columbia accident of 2003.

- A.Radar imaging satellite
- B.Dedicated multi-wavelength space observatory
- C.Navigation satellite
- D.Educational satellite
Show answer
Astrosat was launched on 28 September 2015 by a PSLV and carries instruments that observe the same cosmic source in the ultraviolet, the visible and the X-ray bands at the same time, which is what multi-wavelength means and what makes the mission unusual among space telescopes of its size.
