Patch measures approx 100 mm (4") diameter.
An unofficial patch produced during the shuttle era, the 'Hubble Huggers' patch was produced in the early days of the HST program. The space telescope was troubled from the start when it couldn't 'see' properly. A number of servicing missions were carried out. Hubble was captured, serviced, repaired and improved with fast changing technology. The images obtained were spectacular and have ignited the public imagination ever since.
The first servicing mission to the Hubble Space Telescope saw astronauts install a set of specialized lenses to correct the flawed main mirror in the telescope.
Shortly after the Hubble Space Telescope was deployed in 1990, the observatory's primary mirror was discovered to have an aberration that affected the clarity of the telescope's early images. Fortunately, Hubble, orbiting 353 miles (569 km) above the surface of the Earth, was the first telescope designed to be visited in space by astronauts to perform repairs, replace parts, and update its technology with new instruments. Astronauts repaired Hubble in December 1993. Including that trip, there have been five astronaut servicing missions to Hubble.
