    Which of the following statements are correct regarding EOS-04? EOS...
    • EOS-04 (Earth Observation Satellite - 04) is a radar imaging satellite that can provide high-quality pictures in all types of weather.
    • It can collect photos for agriculture, forestry, flood mapping, soil moisture and hydrology, among other applications.
    • The satellite has a ten-year mission life.
    • The EOS-04 is the fourth spacecraft in a series of the Earth Observation Satellites launched under a new generic designation.
    • It will supplement data from the Resourcesat, Cartosat and RISAT-2B satellite series, which are already in the orbit.
    • It is a radar-imaging satellite that will be deployed in a 529 km Sun Synchronous Polar Orbit, which would have made it a member of the RISAT series sooner.
    • It would replace the RISAT-1, which was launched in 2012, but has been out of commission for some years. Synthetic aperture radars are used by the RISATs to create high-resolution photographs of the terrain.
    • Radar imaging offers a significant benefit over optical imaging, in that it is unaffected by weather, cloud or fog, or a lack of sunshine.
    • It is useful for surveillance, since it can create high-quality photos in all situations and at all hours.

    Which of the following statements are correct regarding EOS-04? EOS...
    Background Information:
    EOS-04 is a radar imaging satellite that is designed to provide high-quality pictures in all types of weather conditions. It is intended to replace the RISAT-1 satellite, which has been non-functional for some years. EOS-04 will also complement the data collected by other satellite series already in orbit, namely Resourcesat, Cartosat, and RISAT-2B.

    Explanation:
    The correct answer is option 'D' - 1, 2, and 3. Let's analyze each statement to understand why it is correct:

    Statement 1: EOS-04 is a radar imaging satellite that can provide high-quality pictures in all types of weather.
    This statement is correct. EOS-04 is specifically designed as a radar imaging satellite, which means it uses radar technology to capture images of the Earth's surface. Unlike optical satellites that rely on visible light, radar satellites can capture images even in cloudy or nighttime conditions, making them highly useful for various applications such as monitoring weather patterns, mapping terrains, and detecting changes in vegetation.

    Statement 2: It would take the place of the RISAT-1, which has been out of commission for some years.
    This statement is correct. RISAT-1, an Indian radar imaging satellite, has been non-functional for some years. EOS-04 is designed to replace RISAT-1 and continue its mission of capturing radar images of the Earth's surface. Therefore, EOS-04 will assume the role previously held by RISAT-1.

    Statement 3: It will supplement data from the Resourcesat, Cartosat, and RISAT-2B satellite series, which are already in orbit.
    This statement is correct. EOS-04 is not intended to replace the existing satellite series but to complement their data. Resourcesat, Cartosat, and RISAT-2B are already operational satellites that provide various types of Earth observation data. EOS-04 will work in conjunction with these satellites, adding its radar imaging capabilities to the existing data collection efforts.

    Conclusion:
    In conclusion, all three statements regarding EOS-04 are correct. It is a radar imaging satellite that can provide high-quality pictures in all weather conditions. It will replace the non-functional RISAT-1 and supplement the data collected by existing satellite series like Resourcesat, Cartosat, and RISAT-2B.
