Q1. What are the different types of urban farming.

•   Paper & Topic: GS III Indian Agriculture

• Model Answer:

• Urban agriculture – what is it?

• Urban farming is often referred to as urban agriculture. It entails growing vegetables and maintaining small livestock like milk cows inconfined areas such bare plots, gardens, verges, balconies, and containers. It can provide food and income for city dwellers. These products can be produced for home use or for sale in surrounding markets.

• Urban agricultural methods that are common include:

• Urban farming methods can be applied in a variety of settings, including schools, roofs, the areas next to restaurants and other businesses, backyards, and apartment and condo complexes. Urban farming methods frequently used include:
• Vertical farming involves growing food crops in layers that are vertically stacked in order to save space and utilise the least amount of energy and water for irrigation.
• By adopting hydroponics, vegetables can be grown without needing soil by growing their roots in nutrient-rich water. Although the design of a hydroponic system can vary greatly, the essential elements remain constant.
• Aquaponics is a metaphor for the relationship between water, aquatic life, bacteria, nutrient dynamics, and plants that cohabit in streams all over the world. By using the waste byproduct from the fish as food for the bacteria, which will then be transformed into the perfect fertiliser for the plants, aquaponics leverages the power of bio-integrating each of these components, learning from nature.
• Shipping The practise of growing plants in containers rather than in the ground is known as container farming. It is also possible to grow non-edible plants in pots. With container farming, weeds are eradicated and soil-borne diseases are less of a problem. When growing in this manner, moisture, temperature, and sunlight can all be more easily managed.
• Growing food on the roofs of buildings is a practise known as rooftop gardening.
• Backyard gardens: It’s standard practise to develop and produce your own food in any backyard space that is accessible.

Q2. Discuss about the Capstone Mission of NASA.

•   Paper & Topic: GS III à Science and Technology

• Model Answer:

• NASA launched a CubeSat the size of a microwave oven that only weighed 55 pounds (25 kg).
• The CAPSTONE mission, also known as the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment, aims to assess a unique, elliptical lunar orbit.
• The satellite is on course for an orbit created for Gateway, a station that will orbit the Moon as part of NASA’s Artemis programme. It was launched today from the Rocket Lab Launch Complex 1 aboard Rocket Lab’s Electron rocket.
• Future spacecraft will be less at danger thanks to CAPSTONE’s verification of cutting-edge navigational technologies and confirmation of the mechanics of the halo-shaped orbit.
• The orbit’s name is a near-rectilinear halo orbit (NRHO).
• The location of it is ideal for balancing the gravitational forces of the Earth and the Moon, and it is substantially extended. This offers stability for lengthy missions like Gateway.

• About:

• It is a diminutive CubeSat weighing 55 pounds that resembles a microwave (25 kg).
• Its objective is to assess a unique, elliptical lunar orbit.
• It aims to help reduce risk for next missions through the verification of advanced navigational techniques and the confirmation of the dynamics of the halo-shaped orbit.
• The orbit’s name is a near-rectilinear halo orbit (NRHO).
• The location of it is ideal for balancing the gravitational forces of the Earth and the Moon, and it is substantially extended.
• It will gain experience with miniature dedicated CubeSat launches to locations outside of low-Earth orbit, such as the Moon.

• Mission objectives:

• For next missions, look into the details of a cis-lunar orbit with a nearly rectilinear halo.
• Show how to enter and stay in this unique orbit, which provides a quick way to travel to and from the Moon.
• Showcase technologies for inter-spacecraft navigation so that future spacecraft can locate themselves in reference to the Moon without merely relying on tracking from Earth.
• Create the foundation for future lunar operations to secure funding from the private sector.
• Discover how to send small, focused CubeSats into orbits other than the Earth’s and the Moon’s.
