Featured Facts

On April 24, 1990, NASA space shuttle Discovery was launched with a special object in its payload bay.  Once in space orbit above the earth, the shuttle’s robotic arm gently lifted out a bus-sized telescope, to be called the Hubble Telescope.

Here are some interesting facts about the Hubble Telescope:

• Dimensions:  44 feet long and 40 feet wide (with solar arrays)
• Weight:  11 tons
• Location and Speed:  355 miles above earth and moving at 17,500 mph

The telescope was named after Edwin Hubble, an American astronomer.  Born in 1889, Hubble would become an authority in establishing many of the dynamics of extragalatic astronomy.  He was a trailblazer in the field of observational cosmology.  He continued his research until his death in 1953.
