Happy Birthday, Hubble!

The Hubble Space Telescope was conceived in 1923, approved by NASA in 1969, and approved by Congress in 1977. Designing and building Hubble was a coordinated effort between NASA Centers and universities, as well as private companies, including Perkin-Elmer Corp. and Lockheed Missiles. It was finally launched on April 24, 1990 and remains in orbit today, 353 miles above the Earth.

The Hubble has a Cassegrain telescope at the front end, followed by several instruments (spectrometers and cameras) that collect data and images.

The Hubble continues to marvel us with new data and images. Eventually, it will be succeeded by the James Webb Space Telescope, which will give us a look even farther back in time (to galaxies that are further red-shifted), through infrared imaging and spectroscopy.
