The Hubble Space Telescope was launched into orbit on April 24, 1990, aboard the Space Shuttle Discovery.

Lyman Spitzer, an American astrophysicist, is credited with the initial idea for a space-based telescope in the 1940s.

The primary mirror of the Hubble Space Telescope is made of beryllium, a lightweight and strong metal.

The Hubble Space Telescope is approximately the size of a school bus, measuring 13.2 meters (43.5 feet) in length and 4.2 meters (13.8 feet) in diameter.

The main scientific goal of the Hubble Space Telescope is to observe the formation and evolution of stars and galaxies, providing valuable insights into the history and structure of the universe.

The first servicing mission to the Hubble Space Telescope was STS-31, which took place in December 1993.

The Hubble Space Telescope has been serviced by astronauts on five separate occasions, with the last servicing mission taking place in 2009.

The Hubble Space Telescope's successor is the James Webb Space Telescope, which was launched in December 2021.

The approximate cost of the Hubble Space Telescope was $2 billion.

The Hubble Space Telescope has five scientific instruments, including the Wide Field Camera 3, the Advanced Camera for Surveys, the Space Telescope Imaging Spectrograph, the Near Infrared Camera and Multi-Object Spectrometer, and the Cosmic Origins Spectrograph.

The approximate lifespan of the Hubble Space Telescope is 25 years.

The Hubble Space Telescope's most famous image is the Hubble Deep Field, which was taken in 1995 and revealed a vast number of galaxies in a small patch of sky.

The Hubble Space Telescope's most significant contribution to astronomy is providing evidence for the Big Bang theory, which is the prevailing cosmological model for the universe's origin and evolution.

As of 2023, the Hubble Space Telescope is still operational and continues to take images and collect data.

The Hubble Space Telescope faces several challenges, including the harsh environment of space, the need for regular servicing missions, and the limited lifespan of its instruments.
