Q1. What are the different types of urban farming?

Paper & Topic: GS III à Indian Agriculture

Model Answer:

What is urban agriculture?

  • Urban agriculture is another name for urban farming. In small spaces like bare plots, gardens, verges, balconies, and containers, it involves cultivating vegetables and keeping small livestock like milk cows. Urban residents can use it as a source of food and revenue. The goods created in this way can be used for personal use or sold in nearby markets.

Some typical techniques for urban farming include:

  • Urban farming techniques can be used at schools, on rooftops, next to restaurants and other businesses, in backyards, and in apartment and condo buildings. Typical techniques for urban farming include:
  • Vertical farming: In order to conserve space and use the least amount of energy and water for irrigation, vertical farming involves planting food crops in layers that are vertically stacked.
  • With hydroponics, it is possible to grow vegetables in water that is rich in nutrients instead of using soil to nourish their roots. Hydroponic system design can take many different forms, but the fundamental components are always the same.
  • The link between water, aquatic life, bacteria, nutrient dynamics, and plants that coexist in streams all over the world is represented by aquaponics. Aquaponics uses the power of bio-integrating each of these parts, taking lessons from nature: Returning the water to the fish in a clean and safe state by using the waste byproduct from the fish as food for the bacteria, which will then be transformed into the ideal fertiliser for the plants.
  • Shipping Container farming is the practise of cultivating plants in containers rather than putting them in the ground. Plants that are not edible can also be cultivated in containers. Weeds are eliminated and soil-borne diseases are less of an issue with container farming. Moisture, temperature, and sunlight may all be more easily monitored when growing in this way.
  • Rooftop farming: Rooftop farming is the technique of growing food on the roofs of structures.
  • Backyard gardens: Using any available space in the backyard to cultivate and produce your own food is a common habit.

Q2. Discuss the Capstone Mission of NASA.

Paper & Topic: GS III à Science and Technology

Model Answer:

  • A CubeSat the size of a microwave oven and weighing only 55 pounds was launched by NASA (25 kg).
  • Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment, also known as CAPSTONE, is a mission intended to evaluate a novel, elliptical lunar orbit.
  • The satellite is headed toward an orbit designed in the future for Gateway, a Moon-orbiting station that is a part of NASA’s Artemis programme. It was launched on Rocket Lab’s Electron rocket from the Rocket Lab Launch Complex 1 today.
  • Through the validation of cutting-edge navigational technologies and the confirmation of the dynamics of the halo-shaped orbit, CAPSTONE intends to lower risk for future spacecraft.
  • A near-rectilinear halo orbit is the name of the orbit (NRHO).
  • It is greatly extended and situated at the exact place where the gravitational pulls of the Earth and the Moon are balanced. For lengthy missions like Gateway, this provides steadiness.

About:

  • It is a tiny, 55-pound CubeSat the size of a microwave oven (25 kg).
  • Its purpose is to evaluate a special, elliptical lunar orbit.
  • Through the validation of cutting-edge navigational technologies and the confirmation of the dynamics of the halo-shaped orbit, it seeks to assist in lowering risk for future missions.
  • A near-rectilinear halo orbit is the name of the orbit (NRHO).
  • It is greatly extended and situated at the exact place where the gravitational pulls of the Earth and the Moon are balanced.
  • It will gain expertise with miniaturised dedicated CubeSat launches to destinations such as the Moon and beyond low-Earth orbit.

Goals of the mission:

  • Check the specifications of a cis-lunar orbit with a near-rectilinear halo for future missions.
  • Demonstrate arriving and remaining in this special orbit, which offers a fast route to the Moon’s surface and return.
  • Showcase inter-spacecraft navigation technologies so that future spacecraft can locate themselves in relation to the Moon without relying just on tracking from Earth.
  • Lay the groundwork for future lunar operations to receive commercial support.
  • Learn to launch small, dedicated CubeSats to orbits other than those of the Earth and the Moon.
