2. Objective: Measure the Earth’s magnetic field intensity and the amount of voltage it produces Expectations: To produce small amounts of power if any, and that the magnitude of the waves will decrease as altitude increases Prove or Disprove: Free Energy theory Discover: Intensity of Earth’s Magnetic Field Why???: To see if this “free energy” is a viable back-up energy source for spacecraft power systems and whether or not the magnetic fields of Earth are a source of magnetic interference at various altitudes Mission Overview
