Space Mirror

The Space Mirror Memorial, also known as the Astronaut Memorial, is a memorial on the grounds of the John F. Kennedy Space Center Visitor Complex in Merritt Island, Florida. It is maintained by the Astronaut Memorial Foundation, whose offices are located in the NASA Center for Space Education next door to the Visitor Complex. The memorial was dedicated in 1991 to remember the lives of the men and women who have died in the various space programs of the United States, particularly those of NASA. The Space Mirror Memorial has been designated a National Memorial by the U.S. Congress.

In addition to 20 NASA career astronauts, the memorial includes the names of a U.S. Air Force X-15 test pilot, a U.S. Air Force officer who died while training for a then-classified military space program, a civilian spaceflight participant who died in the Challenger disaster, and an international astronaut who was killed during the Columbia disaster.

Memorial elements

Two panels show the names of the crew of STS-107

The primary feature of the memorial is the Space Mirror, a large mirror of black granite, divided into 90 smaller panels. The names of the 24 astronauts who have died are scattered over the mirror, with names of astronauts who died in the same incident grouped on the same panel, or pairs of adjacent panels. The names are cut completely through the surface, exposing a translucent backing, and filled with translucent acrylic, which is then backlit with a combination of reflected sunlight (when available) and floodlights, causing the names to glow, and appear to float in a reflection of the sky.

Near the Space Mirror is a granite wall, bearing pictures and brief biographies of those listed on the Mirror.

The design of the Space Mirror was the result of an international design competition. The architectural firm Holt Hinshaw Pfau and Jones, later renamed Holt Hinshaw, won the competition.

Memorial funding

The Astronauts Memorial Foundation and Space Mirror Memorial are funded in part by a specialty vehicle registration plate issued by the state of Florida. Called the "Challenger" plate, it was first issued in 1987, and was the first (and, until recently, most popular) specialty plate issued by the state. The third edition, introduced in 2004, includes Columbia in the text, but is still termed the "Challenger" plate. [2] The memorial cost US$6.2 million.[1]

Defunct sun tracking mechanism

The memorial, as built, incorporated motors and jackscrews to constantly track the sun across the sky in both pan and tilt axes. Parabolic reflectors on the back side of the mirror would then direct the sunlight through the acrylic panels to brilliantly illuminate the honorees' names with sunlight. Supplemental floodlights were used when the sun was inadequate.

In 1997, the tracking system failed, allowing part of the monument to strike a steel beam on an adjacent platform. Insurance paid US$375,000 in repair work, but later, the mechanism again ground to a halt, due to further problems with the slewing ring.[1]

Estimated repairs were on the order of US$700,000, and the Astronauts Memorial Foundation unanimously decided the money would be better spent on educational programs instead. The floodlights were therefore repositioned and are kept burning 24 hours a day.[1]

Honorees

Only those killed during human spaceflight missions or during training for such missions sponsored by the United States are eligible for inclusion in the memorial.[2] For a comprehensive list of space disasters, see List of space disasters.
