Marc Aaronson - Death

Death

Aaronson was killed during an accident in the evening hours of 30 April 1987, in the dome of the 4-m Mayall Telescope of the Kitt Peak National Observatory. Aaronson was killed when he was crushed by the hatch leading out to the catwalk when the hatch was slammed shut on him by a ladder which extended down from the turning telescope dome. A switch on the hatch automatically shut down the dome rotation motor; however, the momentum of the dome kept it moving for a few moments, allowing it to hit the outward opening hatch. This design flaw was corrected after the accident by trimming the ladder and redesigning the hatch to slide sideways, parallel to the dome wall.

Asteroid 3277 Aaronson is named in his honor.
