1. The 'NISAR satellite' is jointly developed by which of the following organizations? [U.P. P.C.S. (Pre) 2023]

Correct Answer: (c) ISRO and NASA
Solution:

NISAR (NASA-ISRO Synthetic Aperture Radar) satellite is a joint Earth-observing mission between NASA and the Indian Space Research Organisation (ISRO) with the goal to make global measurements of the causes and consequences of land surface changes using advanced radar imaging. In 2014, NASA and ISRO signed a partnership to collaborate and launch NISAR. The mission is targeted to launch in 2024. NISAR will be the first satellite mission to use two different radar frequencies (L-band and S-band) to measure changes in our planet's surface less than a centimeter across. NASA is providing the mission's L-band synthetic aperture radar, a high-rate communication subsystem for science data, GPS receivers, a solid-state recorder, and payload data subsystem. ISRO is providing the spacecraft bus, the S-band radar, the launch vehicle, and associated launch services.

2. With reference to 'Astrosat', the astronomical observatory launched by India, which of the following statements is/are correct? [I.A.S. (Pre) 2016]

  1. Other than USA and Russia, India is the only country to have launched a similar observatory into space.
  2. Astrosat is a 2000 kg satellite placed in an orbit at 1650 km above the surface of the Earth.

Select the correct answer using the code given below:

Correct Answer: (d) Neither 1 nor 2
Solution:Astrosat is India's first dedicated multiwavelength space observatory. It was launched on a PSLV-XL on 28 September 2015. This scientific satellite mission endeavors for a more detailed understanding of our universe. One of the unique features of Astrosat's mission is that it enables the simultaneous multiwavelength observations of various astronomical objects with a single satellite. Astrosat, with a liftoff mass of about 1513 kg, was launched into a 650 km orbit at an angle of 6° to the equator by PSLV-C30. Besides NASA, space agencies of the European Union, Japan, and Russia have launched similar facilities into space. Hence, both the statements are not correct.
