    1. Recently, the National Aeronautics and Space Administration (NASA) on 19 October 2017 announced that it would be extending the Dawn mission at Ceres until its hydrazine fuel runs out. Consider the following statements regarding the aim and objective of this extension:
    1. The main priority of the second extension of the Dawn mission is to collect data using the spacecraft’s gamma ray and neutron spectrometer, which measures the number and energy of gamma rays and neutrons.
    2. The spacecraft also will take visible-light images of Ceres' surface geology with its camera, as well as measurements of Ceres' mineralogy with its visible and infrared mapping spectrometer.
    3. The extension will also allow Dawn to be in orbit while the dwarf planet goes through perihelion, its closest approach to the Sun, which will occur in April 2018.

    Which of the following above statements is true?
    a. 1 and 2
    b. 2 and 3
    c. 1 and 3
    d. 1, 2 and 3

    Answer: d

    Explanation:

    The National Aeronautics and Space Administration (NASA) on 19 October 2017 announced that it would be extending the Dawn mission at Ceres until its hydrazine fuel runs out, after which it will continue to remain in a stable orbit around the dwarf planet. Ceres, a dwarf planet, is the largest object in the asteroid belt between Mars and Jupiter. During the extension, the spacecraft will descend to lower altitudes than ever before at the dwarf planet, which it has been orbiting since March 2015.

    The spacecraft will continue its investigation at Ceres for the remainder of its probe by remaining in a stable orbit, where it will stay even after it can no longer communicate with Earth. Mission planners estimate the spacecraft can continue operating until the second half of 2018.

    2. The card, which will be issued every three years, provides information to farmers on nutrient status of soil along with a recommendation on appropriate dosage of soil nutrients to be applied to improving soil health and its fertility.

    Which of the above statements is true?
    a. Only 1
    b. Only 2
    c. Both 1 and 2
    d. Neither 1 nor 2

    3. Recently, the researchers from the University of Porto in Portugal and Ecole Polytechnique in Paris have found the nearly ideal conditions for efficiently creating oxygen from atmospheric carbon dioxide in the future using plasma technology on which of the following planets of the solar system?
    a. Mars
    b. Jupiter
    c. Mercury
    d. Saturn

    Answer: a

    Explanation:

    Mars has nearly ideal conditions for efficiently creating oxygen from atmospheric carbon dioxide in the future using plasma technology, a study has found.

    According to researchers from the University of Porto in Portugal and Ecole Polytechnique in Paris, Mars has 96 per cent carbon dioxide (CO2) in its atmosphere. The research, published in the journal Plasma Sources Science and Technology, shows that the pressure and temperature ranges in the Martian atmosphere mean non-thermal plasma can be used to produce oxygen efficiently.
