(ii) We observe and understand changes .................. (iii) The mission will monitor movements of land and ................... (iv) The satellite will study climate change and support .................. The NISAR satellite mission is a collaborative project between NASA and the Indian Space Research Organisation (ISRO) aimed at transforming how we observe and understand changes on Earth’s surface. Using a unique combination of NASA’s L-band Radar and ISRO’s S-band Radar. NISAR will capture high resolution images in all weather conditions, day or night scheduled to launch from Shriharikota, India, abroad a GSLVMK–II rocket. The mission will monitor movements of land and ice, track natural hazards such as earthquakes, landslides, volcanic erruptions and flood and provide crucial data for studying climate change and managing natural resources. By delivering precise, consistent and global measurements, the NISAR mission will help scientists, policy-makers and communities better predict, prepare for and respond to environmental challenges. The NISAR satellite will study climate changes and support agriculture and ecosystem monitoring by combining data from both Radars. NASA will offer unprecedented accuracy in mapping and measuring Earth’s dynamic processes making it one of the most important Earth Science mission of the decade. A2.

A1. (i) The satellite mission is a collaborative project between NASA and the Indian Space Research Organisation (ISRO). (ii) We observe and understand changes on Earth’s surface. (iii) The mission will monitor movements of land and ice. (iv) The satellite will study climate change and support agriculture and ecosystem monitoring. A2. Natural hazards — earthquakes, landslides, volcanic eruptions, floods. A3. (i) low × high (ii) artificial × natural (iii) inaccuracy × accuracy (iv) unimportant × important. A4. (i) The NISAR satellite will study climate change, won’t it ? (ii) NISAR is going to capture high resolution images. A5. Science is useful to us at every moment of the day. The alarm on our mobile phone wakes us, the electric kettle boils our tea, and the bus or train we take runs on scientific machines. Science has given us electricity, clean water, medicines, vaccines and hospitals that save millions of lives. It helps farmers grow more food with better seeds and fertilisers, and it warns us about cyclones, earthquakes and epidemics. Computers and satellites bring the whole world to our fingertips. In short, from the kitchen to the classroom, science makes our life easier, healthier and safer.
