Mission Overview

Mission OverviewShall 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)

Conclusion Ultimate objective: to

gather quality data and images at high altitude by which we can prove the feasibility of high-altitude balloon observatories

Space Grant is awesome
