Hubble Astronomy The Astronomer: Edwin Hubble The Telescope: Mission, Optics & Repairs Major Discoveries Companions: past, present and future

The Astronomer: Edwin Hubble m Schmidt reflector at Mt Palomar Andromeda: proved many “nebulae” are star systems or galaxies like Milky Way 1929: Expanding Universe

The Mission Launch Date: 1990 First Functionality: 1993 Range: UV, IR and Visible light Major Objectives Outer Solar System Black Holes Age of Universe Total Sky Survey

Backyard Comparison: 1 degree = 60 arcminutes = 3600 arcseconds Best ground scopes: 1 arcsecond Hubble:.05 arcsecond 2 fireflies in San Francisco from NYC

The Telescope: Optics/Repairs 1993 STS-61: Corrective optics 1999 STS-103: Gyroscopes, Computer, Data Recorder 2002: new solar arrays, coolant for IR camera, remove COSTAR
