1.0 Mission Overview
      1.1     Mission Statement
           Our mission is to test the amount of power that can be generated using the Earth’s
      magnetic field as well as measure that field strength as we send a BalloonSat to an
      altitude of 30 km.

      1.2      Background
            We hope to either prove or disprove theories of free energy that can be obtained
      from Earth’s magnetic field proposed by free energy enthusiasts and some well-known
      scientists such as Nikola Tesla (“Power from the Earth's Magnetic Field: Built on
      Facts.”). In order to complete our mission we will send a solenoid and a low current
      sensor on board the balloon satellite. We know that as altitude changes there will be
      changes in the electromagnetic fields and, according to Faraday’s Law any change in a
      magnetic environment in a coil of wire, no matter how small, will generate voltage
      ("Faraday's Law."). The coil of wire, in this case the solenoid, will allow us to see if
      there was any voltage generated by the change in magnetic field. We have selected a low
      current sensor, which we will wire to our solenoid to detect the current, if any, produced
      by the change in the magnetic field. This current can be converted into voltage using
      Ohm’s Law so we can see the amount of potential difference generated by the magnetic
      field. We will be building our own solenoid using copper wire. The focus of our mission
      is not to use the voltage produced in any way during the flight, but rather to obtain
      information about the amount of voltage that is produced. In doing this we are able to see
      if this is a viable method for generating power for satellites and other spacecraft.
      Additionally, we will be using a magnetometer to measure the intensity of the magnetic
      fields of the Earth. This data shall be used as a comparison to see the correlation of
      induced voltage in the solenoid with magnetic field strength. If we do get significant
      voltage produced by the change in electromagnetic fields, then it is important to be able
      to identify what the strength of the field is which causes that voltage. In order to fulfill
      the requirements of our mission we will be using the GPS provided by EOSS, along with
      the magnetometer to measure the intensity of electromagnetic fields as a function of
      altitude.
           We expect to discover that there will be some voltage produced, perhaps very small,
      by the change in electromagnetic field in the solenoid. We chose a low current sensor
      because we do not expect a lot of current to be produced and this will allow us to more
      effectively measure the voltage (current will be converted into voltage using Ohm’s
      Law). We also expect to discover that electromagnetic fields decrease as altitude
      increases.
           We chose this mission because of the potential application of our results. If we are
      able to generate power from only the Earth’s magnetic field, similar methods can be used
      in vehicles and satellites as an alternative source of energy. If, however, we do not create
      significant power, we can effectively disprove free energy theories that have permeated
      conspiracy theories of the past century (“Power from the Earth's Magnetic Field: Built on
      Facts.”). This is a challenging mission; it will push our team to explore and think beyond
      what we already know and the results potentially have real world value.

                3.0 Design
                        Team TBA will fulfill all mission requirements set forth by the RFP and their mission
                    statement by following the procedures in the following section. The main experiments of our
                    mission are to test whether or not energy can be generating using the Earth’s magnetic field,
                    and to measure the magnetic field strength as a function of altitude. This way if we do
                    acquire significant data from our current sensor, we can correlate our derived voltage values
                    with the magnetic field intensity. In accordance with the requirements of the RFP, we are
                    additionally measuring the relative humidity and the internal and external temperatures of our
                    satellite using the HOBO H08-004-02 Data-logger provided by the Gateway to Space course.
                    We will also collect visual qualitative data of our satellite’s journey using the Canon SD 780
                    IS digital camera which has been pre-formatted with software to take pictures every ten
                    seconds. The RFP requires that we maintain the internal temperature of our satellite above -
                    10oC. This requirement will be accomplished by utilizing the heater, insulation, and foam
                    core provided to us. In addition our design will utilize space as effectively as possible in

                                                                 Page 6 of 17                              August 16, 2011
                                                                                                                    Rev A
Gateway to Space ASEN/ASTR 2500                                                            Fall 2011


   order to keep our sensors and camera at optimal operating temperatures for the duration of
   the flight. At the moment we are below the weight limit at 542.5g. Our team leader Quinn
   Kostelecky will ensure that prior to November 5, 2011 that on the exterior of the BalloonSat
   there will be an American flag and contact information if the satellite is lost for any reason.

   3.1 Structures
       The BalloonSat will be built in the shape of a rectangular prism. The structure will be
   12x18x10 cm. The cube will be held together using aluminum tape and hot glue to improve
   the structural integrity. The foam core is a strong, light material used for structure in most
   balloon satellites. Constructing the BalloonSat out of foam core will ensure that our satellite
   will be able to survive the intensity of burst and landing and return back to the ground in a
   condition that will allow the satellite to remain relatively undamaged, fully functional, and
   ready to fly again. This will allow us to return the hardware that was provided to us back to
   the Gateway to Space program in working order. We will cut a hole in the wall our camera is
   against for the lens of the camera to take pictures through. We will use insulation to seal the
   hole so that only the camera lens is exposed to any outside conditions. By using insulation,
   we will prevent heat from escaping the inside of the satellite. We will have a non-metal flight
   tube (diameter is .5 cm.) running through the center of the satellite and attach a flight cord
   using washers and a paper clip. By securing the satellite to the flight string and tube we will
   fulfill our requirements for reaching the target altitude of 30 kilometers. Our satellite’s
   interior walls will be lined with one centimeter thick insulation in order to fulfill
   requirements set forth by the RFP that the internal temperature must remain above -10oC. We
   have minimized the interior volume so heat distribution will be more efficient. In addition, all
   of our components will fit comfortably with little allowable space for movement during
   flight.

   3.2 Experimental Systems
       In order for our satellite to fulfill experiment requirements, we will be utilizing a
   MicroMag 3-Axis Magnetometer to measure the magnetic field intensity and an ACS712
   Low Current Sensor Breakout to measure the current produced by a solenoid which will
   amplify the induced electromotive force from the magnetic field. This solenoid is one of the
   most prevalent limitations on our satellite because not only will it be the heaviest piece of our
   satellite, but its size and effectiveness will be limited by the space and weight of our satellite
   as a whole. The smaller the solenoid, the less significant readings we will acquire. We are
   optimizing the position of our solenoid by placing it on a side of our satellite that is
   unoccupied by any other experimental systems (Diagram 2) to most effectively utilize our
   limited space and to ensure that our center of gravity allows for the vital components of our
   satellite to not take the brunt of the impact at landing.

   3.3 Hardware & Parts
       The hardware necessary to carry out our chosen experiments and fulfill the requirements
   set forth by our mission statements is not provided to us by Gateway to Space. Instead we
   have purchased most of this hardware from SparkFun Electronics. Other materials necessary
   for testing will be bought locally at stores such as King Soopers or Target. See section 5.0
   Budget for specific hardware selections.

   3.6 System Interface
       The first step to making our satellite become an actual working satellite instead of just an
   idea is to build its basic structure out of the foam core and insulation. The most challenging
   task for our team will be the programming required in making the Arduino Uno
   microcontroller record and timestamp data received from the magnetometer and current

                                            Page 9 of 17                             August 16, 2011

   sensor. No one in our team has more than a very basic experience with any programming
   language, so we will need to practice, experiment, and utilize the tutorials provided with the
   Arduino’s Java development based environment software to learn how to program our
   Arduino for our purposes. In addition we will need to research how to properly connect both
   our sensors to the Arduino so that the connections will hold during flight and the Arduino
   will work properly with the magnetometer and current sensor concurrently. We will
   extensively test our sensors and their interface with the Arduino so that we have it perfected
   well before launch day. By practicing and using trial and error we will make sure that our
   Arduino Uno can record and timestamp the data from both the sensors well ahead of time.
   We will connect our sensors to the Arduino microcontroller by utilizing the pins on the
   microcontroller. Our current sensor will be wired to our solenoid and to make sure current is
   flowing we will perform a test as explained below.

4.0 Management
   4.1 Organization
       Our team consists of six engineering students: Quinn Kostelecky, Roshan Misra, Gloria
   Chen, Vincent Staverosky, Jacqueline Godina, and Raymond Auyeung. Our organizational
   chart is a circle because we do not want to isolate anyone by making them focus on a specific
   aspect of BalloonSat construction. This way, everyone answers to everyone so we can all
   have input in every area. Every team member, however, has a responsibility to make sure one
   or more system of the satellite is completed effectively and in a timely manner so our team
   has some structure and direction. Quinn Kostelecky is our team leader where he will be
   delegating and making sure the whole system comes together well and on-time. Roshan
   Misra is the experiment lead, so he will be making sure all the systems for our experiment,
   such as measuring the magnitude of electromagnetic fields and measuring the amount of
   voltage produced from the EM waves, are functional. Gloria Chen will be our camera lead
   where she will make sure the camera will be stabilized during the flight. Additionally, she
   will be our safety lead where she will ensure that everyone is safe during testing and building
   of the BalloonSat. Vincent Staverosky will be our HOBO and Arduino lead. He will ensure
   that the HOBO records accurate data and is responsible for programming the Arduino.
   Jacqueline Godina will be our structure lead where she will be making sure our structure is
   able to survive impact and burst. She will allow all our materials to fit while trying to obtain
   a center of gravity which will direct forces upon landing away from fragile components.
   Raymond Auyeung is our heater and insulation/ budget lead. He will verify that the
   BalloonSat can maintain an internal temperature above -10°C as well as document all
   purchases, making sure we stay under budget.

   4.2 Schedule
       The following is a timeline of when we want to complete tasks crucial to the BalloonSat.
   We scheduled the entire satellite to be completed by October 26 so we have a little bit of
   leeway if some systems are more time consuming than expected. If possible, we will
   complete tasks prior to dates listed in schedule. Weekly meetings will be held on
   Wednesdays where everyone team member will be informed of any progress made as well as
   objectives for the coming week.

5.0 Budget
       The budget for the team will be managed by Raymond Auyeung. He will document all of
   the purchases we make. We will buy the least expensive materials that will still fulfill
   mission requirements. We will consult with not only our team, but also Professor Koehler
   before making purchases to ensure we only buy materials that we will actually need. All
   purchases will be documented through receipts and order forms that will be turned into
   Professor Koehler.

6.0 Test Plan and Results
       In order to ensure a successful mission on launch day, it is critical to thoroughly test and
   make adjustments to the BalloonSat prior to flight. Testing enables us to effectively predict
   how the satellite will perform during flight. Every sensor shall be calibrated on the ground so
   that the differences between ground results and mission results can be compared to make
   conclusions on our experiments. Further detail will be provided under specific sensor
   calibration below. Structural testing allows us to see if the BalloonSat can withstand the
   conditions of near-space, burst, and recovery. Effective testing will allow us to make changes
   to design perform better in flight and will help guarantee fulfillment of mission requirements.

   6.1 The Drop Tests
       In order to test the structural integrity of the BalloonSat, we will drop it from
   approximately 6.6 meters and roll our BalloonSat down a flight of stairs in two separate tests.
   These tests will simulate the forces it will undergo while landing and during burst as well as
   give us an idea how the BalloonSat will react in these situations. After the tests, thorough
   examination of structure, internal components, and insulation will take place. If any
   significant damage is taken, the BalloonSat will effectively be re-engineered to address those
   issues. If significant change is necessary, the drop test must be repeated to ensure it is ready
   for flight.

   6.2 The Whip Test
        The whip test consists of a tester swinging the structure around by its flight string. This
   simulates the potential motion the BalloonSat must be able to handle during flight. The
   critical aspect that is tested is the flight string attachment system. It is essential to have a
   secure connection because no mission objectives will be met if the BalloonSat detaches from
   the flight string and is unable to be recovered. This test will allow us to make any necessary
   changes to ensure proper performance during flight.

   6.3 Cooler Test:
       Since the satellite will go through a section of its flight in extremely cold temperatures,
   we need to make sure that our insulation system can keep the internal temperature above -
   10°C under those conditions. To do this, we will place the BalloonSat into a cooler filled with
   dry ice for the estimated duration of the mission. During the test, the HOBO and temperature
   probes will track the temperature of the structure so we can qualitatively confirm our satellite
   can cope with similar temperatures that will be encountered during the mission. If significant
   changes are made, the test will need to be repeated to ensure proper functionality during the
   mission.

   6.4 Camera Test:
       The Canon SD 780 IS programming will be tested by running it multiple times, saving
   pictures on SD card, and uploading the photos to a computer. This will ensure not only that
   the program works, but that the whole system is functional.

   6.5 Current Sensor:
       The solenoid power circuit is a very important part of our mission and it is necessary to
   test it to fully understand how it will work during our mission. When we have successfully

                                           Page 14 of 17                             August 16, 2011
                                                                                              Rev A
Gateway to Space ASEN/ASTR 2500                                                            Fall 2011


   hooked the solenoid to our current sensor and Arduino, we will test the solenoid’s capability
   of setting up a current in the circuit using a magnet. We will pass the magnet through the
   solenoid, rotate the solenoid, and try various other relative motions to see potential current
   levels we will need to record in the mission. Additionally, we will pass a known current
   through the current sensor (with a battery of known voltage and a circuit with known
   resistance). We will compare the known voltage to the value picked up by the sensor so we
   can calibrate if necessary. This current will be within the range that the sensor can detect.
   This will also allow us to test our ability to record the reading from the current sensor with
   the Arduino.

   6.6 HOBO:
       We will test the HOBO’s measuring capabilities and our ability to record and recover the
   data prior to launch. We will do this by measuring the temperature that is already known and
   retrieving those readings on a computer so we can make changes to ensure accurate
   temperature measurement during the mission.

   6.7 Magnetometer:
        It is critical to calibrate and test the magnetometer prior to flight to ensure that accurate
   and relevant data is collected during the mission. The magnetometer will be zeroed with no
   electronics or magnets in close proximity (except those running it) and a magnet of known
   strength will be brought near it to test its measurement. Zeroing the magnetometer at ground
   level will mean that we have a reference point of the Earth’s magnetic field strength with
   which we can compare our altitude data against to see relative gains or losses in magnetic
   field strength with altitude. This will also allow us to eliminate impact on results of
   interfering magnetic fields created by onboard hardware between the test and in-flight data.
   At this time we can also test our ability to store, recover, and compile data with the Arduino.
   We will also take a baseline reading during our full-length flight simulation of the magnetic
   fields created by the hardware running on the satellite. This will help us filter out interference
   so we can more effectively measure the Earth’s magnetic field strength.

   6.8 Full Mission Simulation:
       After all other tests are completed, a full-length mission simulation will be run to check
   that all systems are working together properly and without error. This will be done well
   before the launch date in order to allow for time to fix any potential problems. Every
   subsystem shall be checked for any errors and all data will be analyzed. This will provided a
   basis for comparison of in-flight data. This will make it possible to make conclusions on
   magnetic field changes with altitude and our current sensor readings. Any current generated
   in the solenoid circuit during the simulation will be assumed to be created by other
   electronics in the satellite; therefore, similar readings can be accounted for during flight. This
   simulation is essential to confirm proper BalloonSat functionality prior to launch. This test
   will be done before launch with enough time to make changes to the BalloonSat if the need
   arises.

       We are hoping that the results we get will prove or disprove free energy theories to see if
   we are actually able to get energy just from the Earth’s magnetic field. If the data comes back
   and we receive measurable current and voltage that was produced by the solenoid, we may
   potentially validate theories of energy generation from Earth’s magnetic field. This could
   then become another source of power for use on future satellites. We, however, do not
   believe significant power will be generated through our procedure. Electromagnetic flux may
   not change fast enough to induce a significant emf (electromotive force). If this is true, we
   can effectively disprove some free energy theories. Further means of experimentation,
   however, may yield different results. If satellites had similar set ups in their payloads, they
   may generate a larger amount of power because they move significantly faster than the
   BalloonSat will. Any results found in this experiment would theoretically be amplified when
   used on an orbiting satellite.

   7.2 Analysis and Results
        After the BalloonSat has been retrieved, we will take the SD card from the Arduino and
   download the data to a computer. In order to compute the data, we will use a JAVA based
   development environment that is downloadable from SparkFun.com. Once the data is
   retrieved, we will need to change the current we’ve measured from amps to volts using
   Ohm’s Law (the resistance of the circuit will be measured while on the ground in order to dot
   this). Additionally, we will make a data plot of the magnetometer versus time and compare
   that to the EOSS GPS readings of altitude at the same time. To obtain the data from the
   HOBO we will connect the HOBO to a computer and then generate a graph for the data that
   it collects using the Boxcar software program provided to us. Pictures will be uploaded to a
   computer as well.
        All results will be plotted with time and with altitude. This will allow for comparison
   between results to see how temperature and magnetic field strength will affect voltage
   generated in the solenoid circuit. These results will also be compared to data from mission
   simulation to see what changed between flight and stationary tests. This will allow us to
   eliminate any commonalities in order to see what the actual effect of the near-space mission
   is on magnetic field strength and voltage generated. Without this comparison, our results
   would be meaningless.
