Space Craft: HRF (Hunter, Rachel, and Faith. Launch date, June 1st
Experiment 2
Hypothesis: If we bring a bucket of water to Mars than 8 ounces will evaporate in 1 hour.
Solar Energy
To produce solar energy on our spacecraft we will need to use solar panels.
Launching
To launch the spacecraft we first need to know how much the whole spacecraft's mass is. We calculated the mass of the key components of the spacecraft.
Experiment 1
Materials
1 gallon of water
1 bucket
timer
Procedure
1) Get on Mars during Mar's Summer.
2) Fill the bucket with 16 ounces of water and set it on the Mar's ground.
3) Set a timer for 1 hour and go back on spacecraft.
4)Go back to bucket and check after the hour is up and record how much water has evaporated.
5) Repeat 2-4 four times but for number 2 fill the bucket back to 16 ounces.

Calculation of the Force Require for Launching
The mass of the three components of the spacecraft are:
756,445.5628 kg- External Tank
1,179,340.16 kg- 2 Solid Rocket Boosters
99,318 kg- Orbiter
Then we calculate all the mass of the whole ship which is those parts added together which is: 2,035,103.8 kg
The Force of Launching
The force of launching was found by N=ma which is:
40,580,699,510,000 N
Hypothesis: If a person jumps on the moon then they will get higher than they did when they jumped on earth

Data Table
1) Choose one person to be the jumper
2) Have them jump as high as they can on earth
3) Measure how high they jump
4) Record data
5) Repeat 4 more times
6) Find the mean of the data
7) Go to the moon
8) Have the same person jump as high as they can on the moon
9) Record data
10) Repeat 4 more times
11) Find the mean of the data
12) Compare the means

Summary
The moon and the earth both have different pulls of gravity that effect easy tasks like walking and jumping. We did this experiment because it shows the effect gravity has on a person jumping.
Summary
This experiment is important because it will show whether or not water can stay on mars for a long time, which will show if Mars is able to sustain life.
Travel Plan
When in space we will see many planets on our trip, such as, the moon, Mars, and Saturn.
First we will go to the moon(earth's moon) which is very important to our expedition because our first experiment takes place there.
MOON
We will have to attach solar panels to the side of our spacecraft that will convert the energy from the sun into electricity.
Mars
Chemical Energy
Next on our journey we will go to Mars which is an important to our Experiment #2.
Nuclear Energy
Saturn
To produce chemical energy on our spacecraft we need to use chemical reactions. The difference energy equal to the reaction will produce energy that will convert into electricity.
To produce nuclear energy in our spacecraft we will need to use an RTG or radioisotope thermoelectric generator.
For our last stop we will visit Saturn but will have to stay at a safe distance to observe the jagged rings that are made up rock and ice.
The RTG uses devices called thermocouples to convert plutonium-238 decay into electricity.

To produce chemical energy on our spacecraft we will need to use a batch reactor.
Communication
Outer Space Travel
Landing
Solar panels have a mass of approximately 50 pounds.
For communication, we will need a Low-Gain Antenna, with a mass of ,
a 40-centimeter aerial protruding from the spacecraft. We could also use a High-Gain Antenna a 1.8-meter in diameter the high-gain antenna, with a mass of , is attached to one face of the spacecraft that will communicate efficiently.
Batch reactors have a mass of approximately 5.7 tons
