2024年11月5日 · This timeline describes Hubble’s history from the first proposal of a space telescope by Lyman Spitzer in 1946, through the completion of Hubble’s five servicing missions in the 1990s and 2000s, and to many of the significant observations and discoveries Hubble has made during its years in orbit.

2025年2月13日 · Hubble was launched April 24, 1990, aboard Space Shuttle Discovery's STS-31 mission. Soon after launch, astronomers realized that the primary mirror had a flaw called spherical aberration, which caused its images to be blurry.

With all of Hubble's pieces in place by December 1985, NASA planned for an October 1986 launch. But Hubble's future would be in limbo once again, when tragedy struck on January 28, 1986.

2025年1月14日 · The Hubble Space Telescope was launched into orbit by space shuttle Discovery on April 24, 1990. Hubble orbits about 332 miles above Earth. It is the length of a large school bus and weighs as much as two adult elephants. Hubble travels about 5 miles per second.

2020年4月24日 · The launch of the Hubble Space Telescope took place on April 24, 1990, during the STS-31 mission. The Shuttle flew to an unusually high 380-mile orbit to ensure that Hubble would operate above as much of the Earth’s atmosphere as possible.

2008年4月18日 · April 24, 1990: Launch aboard Discovery on STS-31. Scientists later uncover a spherical aberration in the mirror that leads to slightly blurred images. December, 1993: Servicing mission aboard STS-61 to improve Hubble's image quality by installing corrective optics.
