2. Operation H.A.L.O.

3. Mission Overview The goal of our mission is to determine the altitude at which it becomes possible to image stars with little atmospheric distortion at all hours of the day. We expect that our balloon satellite will return useful data which will aid in determining if high altitude observatories are capable of taking and returning high quality photos of distant galaxies.
