The Hubble Space Telescope

After Sullivan's first Shuttle mission and her historic space walk, she had to wait six long years to get back into space and help launch the Hubble Space Telescope.

Flying 330 nautical miles above the Earth, Hubble sees 10 times clearer than Earth bound telescopes peering up through the Earth atmosphere. Freed of this atmospheric distortion, Hubble can see objects an incredible 14 billion light years away! Hubble is a time machine looking into the depths of our past. It shows us ancient quasars and long-extinct galaxies and sends back clues about the earliest origins of our universe.

The 23,981 pound, 43 1/2 foot long Hubble is the largest scientific payload ever launched into space.
