5. Mission Overview Shall demonstrate the feasibility of high-altitude balloon based observatories Shall analyze and understand solar phenomena by observing the Sun in Hydrogen-Alpha and Calcium(II) Potassium wavelengths  Observations of the Sun currently rely on ground and orbiting solar observatories, hindered by cost, accessibility, and atmospheric interference  James Webb Space Telescope ~ $1.6 billion  Kepler Telescope ~ $600 million  Average Shuttle Launch ~ $450 million  Mission offers analysis of:  Lower Chromosphere (Ca II – K)  Mid Chromosphere (H-A)  Solar Magnetic Field (both)  MicroFlares (both)  Arch Filaments (both)
