Dhivyashree's Project

About Me: My name is Dhivyashree Loganathan. I am studying in 6th std, Indian School Sohar, Oman. I like to know about space. I got interested when I studied about different planets. I want to become a rocket scientist.

3D Rocket Design:

Here are the details about the rockets which I have designed:
1) Grand space shuttle

It is the mission to send five astronauts to Mars in search of life in mars. It has 2 liquid boosters for thrust and a propollent tank. after the 0th and the1st stage falls down the space shuttle is in space no, after a few days it will reach mars.
2) Space explorer
It is a mission to explore the universe. It is a combination of parallel and serial staging. It has 2 boosters and three stages tandemly.
3)Exquisite rocket
It describes the parts of a rocket engine
yellow = combustion chamber
orange= frame of the rocket

Solid propellant rocket:

This is my solid rocket activity, this contains ten match stick chemicals. I got this result after four rocket test failures. The fifth rocket was a success. The fifth one had four match stick chemicals but it did not fly far. This is the video of the sixth rocket. It has ten matchstick chemicals and it flew very far. It is well known that “Failure is the stepping stone for success”, I learnt a lot from the mistakes that I made after the four rocket launch failures and corrected them. Those mistakes were:
I did not remove the chemical from the matchstick instead I just kept it with lot of wood pieces
I did not seal the nose cone perfectly
I did not give enough space between the launching stick and the propollent
I did not place the candle right below the chemical

Static Hubble telescope paper model The Hubble telescope was launched in low earth orbit on1990, which is still in operation. This activity was not too easy or tuff because at times I got stuck. It was made from a chart sheet. I have sealed and assembled it with liquid glue and tape. For the dowels I used four toothpicks for each dowel,so that I would get the perfect size of the skewer used in the model.
The rubber band powered rover was a very easy ,simple and interesting activity . I used cardboard, iron wire , thermocol, skewer and rubber band. First I cut two circles for the wheels and a rectangle. I folded the rectangle into the body of the rover. I connected the wheels and the body with a skewer. Then I taped the wheels well to the skewer. Then I knotted the band to the skewer and connected it to the end. Now it's time to make the fore wheels. Now I bent the wire, took six thermocol circles ,made them into two circles and inserted them. now i have connected it to the rover and it is completed.
I would also like to share some discoveries I made so when you lose one hind wheel it will take a round.when you turn your wheel to the direction you want to go ,it will take a turn If I change the direction of placing the rubberband it would go backward or forward(according to the direction of the rubberband).and remember these precautions do not forget to tape the hind wheels.
Never lose hope if you don't get the materials,use your creativity.

Static Juno probe paper model I have made the JUNO satellite. I have attached the picture with this email and sent the description.
The Juno satellite is a space probe that orbits Jupiter. It was launched on August 5, 2011. This model was inspired from NASA's JUNO satellite. I have printed these pieces on an A4 sheet and assembled them. The material used was paper, glue, scissors, iron wending wire with a base(for assembling), toothpick and black paint. First I assembled the pieces according to the guide with glue and then l made toothpick braces as given and painted, they were used for the solar panels support. Now I have completed the model, made a hole and attached it to the base.

Dhivyashree Loganathan's Project I participated in the space chase contest conducted by givemefive .

Purpose of the rover

It helps the astronauts to move and research further from their settlement on the moon.

If the astronauts want to discover the moon further and perform the experiments suggested by universities, they could do it with the help of this rover

It is well equipped that collected samples can be stored or experimented from the rover and also transfer data to earth

Instrument & their function

Infrared imager- this helps the astronauts to know the temperature outside or soil

High resolution cam- it helps in capturing images of the moon surface

Earth sensor- it helps the antenna to face the earth every time

Parts of the rover

Controlling system for the whole rover

Communication system

Air and pressure control system

Power system

Instrument and equipment holder

Communication system

This contains a panel for delivering the data and receiving commands from the earth.

It also has telemetry antenna to send and receive signals. This is the main part of the communication system as this helps to connect the earth

The antenna connects the earth for navigating the rover.

layers of insulation



Space grade plastic



Aluminized mylar



How do astronauts fulfill their needs

Food and water- they are kept and stored in the food strap

Air- there are air vents and oxygen supply for astronauts in the rover They have sanitary supplies (if needed) in one hour travel.

Instruments and equipments are provided in the tool strap. There are astronaut suit for going out of the rover and collect samples manually.

All about pressure, power and temperature control of rover

The atmospheric pressure maintained will be 1

The thermal control is done by fluids and layers of insulation which will help the rover to be in the room temperature

Power is produced by solar panels. The energy is stored in battery for the rover functioning Lastly about control panel of the rover

It controls:

➔ The air and power supply

➔ Makes the rover move

➔ Gives warning if somethings wrong with the rover

➔ Controls the door

➔ It is connected with the highresolution cam which helps in finding obstacles on the way.

These are the things it could control.
