Sarat Chandra IAS Current Affairs of 27th March-2021


  • Greater One-Horned Rhino


Greater One-Horned Rhino

Context: The claims by different political parties over significant reduction in poaching of Greater One-Horned Rhino has become an issue in Assam Assembly Elections.

  • The Greater One-Horned Rhino is one among the five different species of Rhino and out of 5 only the Great One-Horned Rhino is found in India.
  • There are three species of rhino in Asia—Greater one-horned (Rhinoceros unicornis), Javan and Sumatran.
  • IUCN Red List: Vulnerable.
  • Wildlife Protection Act, 1972: Schedule I.
  • Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES): Appendix I



Context: NASA and ISRO are collaborating on developing a satellite called NISAR

  • NISAR is an SUV-sized satellite that is being jointly developed by the space agencies of the US and India.
  • The name NISAR is short for NASA-ISRO-SAR. SAR here refers to the synthetic aperture radar that NASA will use to measure changes in the surface of the Earth.
    • Essentially, SAR refers to a technique for producing high-resolution images.
    • Because of the precision, the radar can penetrate clouds and darkness, which means that it can collect data day and night in any weather.
  • The partnership agreement was signed between NASA and ISRO in 2014.
    • NASA will provide one of the radars for the satellite, a high-rate communication subsystem for science data, GPS receivers and a payload data subsystem.
    • ISRO, on the other hand, will provide the spacecraft bus, the second type of radar (called the S-band radar), the launch vehicle and associated launch services.
  • The satellite will be launched in 2022 from the Satish Dhawan Space Center in Sriharikota, India, into a near-polar orbit.
  • It will scan the globe every 12 days over the course of its three-year mission of imaging the Earth’s land, ice sheets and sea ice to give an “unprecedented” view of the planet.



Context: Eritrea will pull its troops out of Ethiopia’s northern Tigray region, Ethiopian Prime Minister Abiy Ahmed, winner of the 2019 Nobel Peace Prize, said

  • The Tigray Region is the northernmost of the nine regions (kililat) of Ethiopia.
  • Tigray is the homeland of the Tigrayan, Irob and Kunama peoples.
  • Tigray is also known as Region 1 according to the federal constitution.
  • Its capital and largest city is Mekelle.
  • Tigray is bordered by Eritrea to the north, Sudan to the west, the Amhara Region to the south and the Afar Region to the east and south east.



Context: The third phase of the Indian beamline project, a facility for materials research set up under India-Japan Scientific and Technological Cooperation, was initiated on March 23, 2021, with special focus on industrial application research.

  • The phase would increase the number of young researchers from India to be trained in advanced X-ray techniques of material research.
  • Besides, steps will be taken to allocate more beamtime so that more researchers can get access to it. At present, only 50 % of Indian researchers who apply receive beamtime.
  • The Indian beamline has been constructed and maintained by Saha Institute of Nuclear Physics (SINP), Kolkata and Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), Bangalore; in Japanese synchrotron light source Photon Factory (PF) of High Energy Accelerator Research Organization (KEK), with support from Nano Mission, Department of Science and Technology (DST).
  • This India-Japan Scientific and Technological Cooperation project was initiated between the DST and the KEK on 24 July 2007.
  • In the first phase (2009-2015) of this project, an X-ray beamline (BL18B) was constructed by SINP in PF. In the second phase (2016-2021), JNCASR and SINP jointly developed the beamline further to cater to the need of various users from India.
