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. It can be used as a UAV for small package delivery or vertical takeoff and landing, as well as long-endurance surveillance for agriculture, mapping, and other applications. Its modified scaled-up version can be used as a persons air vehicle.

Q5 [2015]: The term ‘Goldilocks Zone’ is often seen in the news in the context of:

(a) The limits of habitable zone above the surface of the Earth

(b) Regions inside the Earth where shale gas is available

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

(d) Search for meteorites containing precious metals

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.

2. National Aeronautics and Space Administration and US Geological Survey USGS.
3. European Space Agency and US Geological Survey USGS.
4. National Aeronautics and Space Administration and Indian Space Research Organisation
Answer: National Aeronautics and Space Administration and US Geological Survey USGS.
Solution: Recently, NASA has launched an earth monitoring satellite called Landsat 9 from Vandenberg Space Force Base in California. The satellite is a joint mission of NASA and the US Geological Survey USGS. This satellite is referred to as NASAs new eye in the sky that will help study climate change. Landsat-9 is the continuation of a series of Earth-observing spacecraft stretching back almost 50 years. The first Landsat satellite was launched in 1972 and since then, Landsat satellites have collected images of earth and helped understand how land usage has changed over the decades. In 2008, it was decided that all Landsat images will be free and publicly available and the policy has helped scores of researchers, farmers, policy analysts, glaciologists, and seismologists. Landsat images have been used to study the health of forests, coral reefs, monitor water quality and melting glaciers. The Landsat 9 joins Landsat 8 that was launched in 2013 and the satellites together will collect images of Earths surface. It takes 8 days to capture the whole Earth. Landsat 9 carries instruments similar to the other Landsat satellites, but it is the most technologically advanced satellite of its generation. The instruments aboard Landsat 9 are the Operational Land Imager 2 OLI-2 and the Thermal Infrared Sensor 2 TIRS-2. OLI-2: It captures sunlight reflected off Earths surface and studies the visible, near-infrared, and short wave infrared portions of the spectrum. TIRS-2: It has a four-element refractive telescope and photosensitive detectors that capture thermal radiation and help study the Earths surface temperature. Along with the European Unions Sentinel-2 satellites, the Landsat Satellite will provide better estimation of the extent of climate change.
