THE ROTATINHG GARDEN

In our project THE ROTATING GARDEN we mainly focus about the astronaut's foods.

Food is the first line of defense to maintain astronaut health and performance. Pre-packaged food has been used to meet astronaut food requirements since the start of the space programs. However in missions last up to two or three years, key nutrients and vitamins in currently available version of pre-packaged foods will begin to lose and the food may also suffer a decline in palatability and acceptability.

To solve this problem we designed a crop production system which will suitable for the micro gravity in the space ship. Our crop production system rotates around it's middle axle and create an artificial micro gravity to the eight corns around it.

Our crop production system has five main parts.

Volume-7.5 cubic meters

Growth area is closed to the cabin environment

1. planting corns- There are 8 planting corns
2. controlling corn- There are 8 controlling corns
3. middle axle
4. motor
5. dynamo

We are going to fill the growth media at the vertex end of the white color corns. So the roots grow to the vertex side due to the artificial gravity while the trunk grows to the base surface side.

When we rotates our system the water drops also face to a centrifugal force and flows easily to the growth media.

We have to supply power to a motor ,which is connected to one end of the axel .And while it is rotating a dynamo at the other side creates electricity for the led bulbs and other sensors from electromagnetic induction.

planting corn

planting corn is the white color corn which we use to grow plants.

• height-1m
• radius-50cm
• The base surface is opened and the curved surface is made by white polyethylene
• There are eight planting corns.
• There is a rubber grip and seven sealing clips which connect the planting corn with the controlling corn at the base side.
• planting corn can separate in to 3 parts .

part 1 -the part near to the vertex

when we want grow plants that grows above the ground we can fill growth media up to this part 1

eg; tomatoes, wheat

part 2- the middle part

when we want to grow plants that grows underground we can fill growth media up to this part 2

eg; potato, reddish, beet root

The growth media of these planting corns is been covered by the planting beds

• There are 5 planting pillow in one planting bed
• Planting beds are made by polyethylene
• Planting pillows are made by Teflon coated black Kevlar with a Nomex bottom .
• The seeds are glued into wicks, the glue is a guar gum which is using in veggie program,.
• These is a whole at the middle of the planting bed for the water tube which come from the controlling corn
• When astronauts harvest the crops they can cut non eatable parts of the plant and put them under the plant bed to the growth media.

Controlling corn

• Height-30cm
• Radius-50cm
• Made by polyethylene

Water injecting end is sent to the growth media through middle whole in the planting beds

Base surface of the each controlling corns contain,

• A camera
• LED bulb system
• O2 sensor and controller
• Infrared temperature sensor
• CO2 bottle
• Environment control system
• All of these cameras and sensors get power from the dynamo at one end of the middle axle

Middle axle

• Length-2.5m
• Radius-10cm
• Outer membrane is made by polyethylene, it doesn't rotates
• Connected to a motor and to a dynamo at each ends.

• Motor gets power from out(space ship's electricity) and it rotates the middle main water tube with it's connections .
• The motor also rotates the dynamo and it helps the dynamo to produce electricity.
• The electricity is used by the controlling corn,.
• There are water restrictions cubes at two ends of the middle water tube which stop water flowing in to the motor or dynamo.

From this main water input astronauts can put water and liquid fertilisers to the plants.

▪︎Our project is deployable and storable when not in use

▪︎We can separate planting corn and controlling corn from the middle axle and place it on the lunar or matian surface in partial gravity

▪︎The polyethylene structure can survive from deep space radiations.

Canadian space agency data

Nurvik project

space apps experience & what we learn

This is our first space app challenge. And this gave us a great knowledge about how to handle space agency data and how can we use those data to solve a problem in time of period of 48 hours .

This opportunity make us path to learn about the risks in space and how space agencies manage their risks and give protection to the astronauts.

what inspired us to choose this challenge

Gardening have become world wide habit of people nowadays due to the lockdown season as people have enough time to pay their attention to their home .I also create a garden at my home .And now l love very much to sea how seeds grows . That passion inspired me to choose this challenge.

We would like to thank our family members for their support in this 2 day challenge
