educationprovince.com

Explanation: GL-10 is a remotely piloted plane similar to an Unmanned Aerial Vehicle (UAV). It is designed and developed in such a way that it can take off like a helicopter and fly like an airplane. It is a battery-powered 10-engine with a wingspan of 3.05 meters. Eight electric motors are mounted on the wings. 2 electric motors are mounted on the tail. It weighs a maximum of 28.1 kilograms at takeoff. Due to its versatile vertical takeoff and landing ability, it produces less noise.

Answer: (c) Search for the Earth-like planets in outer space

Explanation: The Goldilocks Zone is the livable zone around a star where the temperature is not too hot and not too cold for liquid water to exist on a planet. It is a metaphor for the childrens story Goldilocks and the Three Bears, in which a young girl selects from sets of three objects, eschewing the extremes (such as those that are enormous or small, hot or cold) and fixing on the one that is just right in the middle. The Goldilocks zone of the Sun surrounds the Earth. All of Earths water would freeze if it were found where the dwarf planet Pluto is; however, all of Earths water would boil out if it were found where Mercury is.

UPSC Practice Questions on NASA Space Missions

Q1. The Parker Solar Probe Mission sometimes mentioned in the news recently is related to
1. Indian Space Research Organisation
2. National Aeronautics and Space Administration
3. European Space Agency
4. Japan Aerospace Exploration Agency
Answer: National Aeronautics and Space Administration
Solution: Scientists using data from NASA's Parker Solar Probe have assembled the most complete picture yet of the inner structure and behaviour of the large cloud of space dust, known as the zodiacal cloud, that swirls throughout the solar system. They found three dust populations in the cloud: Most of the grains are being slowly pulled in toward the Sun alpha-meteoroids. The second population is generated as grains in the swirling cloud collide, creating fragments so small that they are pushed out of the solar system in all directions by pressure from sunlight beta-meteoroids. A third group, probably created when a tube of cometary debris collides with grains from the first two populations, is scattered out in a distinctive wedge shape. The sources of zodiacal clouds/interplanetary dust particles IDPs include at least asteroid collisions, cometary activity and collisions in the inner Solar System, Kuiper belt collisions, and interstellar medium grains. NASA's historic Parker Solar Probe mission will revolutionize our understanding of the sun, where changing conditions can propagate out into the solar system, affecting Earth and other worlds. Parker Solar Probe will travel through the sun's atmosphere, closer to the surface than any spacecraft before it, facing brutal heat and radiation conditions and ultimately providing humanity with the closest-ever observations of a star.
