In which of the following year, IRS-1A was launched

  • A.1982
  • B.1987
  • C.1988
  • D.1990

Answer: C

IRS-1A, the first of the Indian Remote Sensing satellites, was launched on 17 March 1988 from the Baikonur cosmodrome in the Soviet Union. IRS-1B followed in 1991. The years 1982 and 1987 are before the launch, and 1990 does not match, so 1988 is the answer. The Indian Remote Sensing programme later added IRS-1B, IRS-1C and IRS-1D, and the series has supported mapping of crops, forests, water and land use.
