He would join NASA as an astronaut in 1992, where he'd provide mission support for the crew of STS-61, the 1993 mission to repair Hubble's faulty eyes with corrective optics.

The Hubble Space Telescope was equipped with corrective optics during a 1993 shuttle servicing mission, counteracting a flaw in the observatory's primary mirror. Hubble has operated at the ...

Over the years, Hubble’s advanced optics, including its nearly 8-foot-wide mirror, have allowed it to resolve objects 1,000 times better than the human eye.

The Hubble Space Telescope is making waves again, this time for a snapshot of a spiral galaxy located 250 million light-years ...

It was a set of corrective optics, installed by astronauts in 1993 after the Hubble's main mirror -- much to NASA's embarrassment -- had turned out after launch to be slightly misshapen.

MIT hosted a symposium on Nov. 13 to commemorate the 20th anniversary of STS-61, the space shuttle mission that famously repaired the Hubble Space Telescope's faulty optics.

On 20 May, 1990, Hubble sent back a blurry, ... As replacing the mirror in orbit was close to impossible, a new optical component, the Corrective Optics Space Telescope Axial Replacement ...

Though the galaxy lies several tens of millions of light-years away, modified optics incorporated within the WFPC-2 allow Hubble to view M100 with a level of clarity and sensitivity previously ...

Astronomers have developed a new visible-light adaptive optics (AO) system for a 6.5 meter telescope in Chile's Atacama desert. The new AO system produces the sharpest telescopic images ever ...
