Nasa has set up a website for members of the public to upload photos or video they took of the space shuttle Columbia disintegrating.
Nasa hopes images held by the public could aid investigators in discovering how the Columbia broke up over Texas on Saturday, only minutes before it was due to land in Florida. Taking investigative cooperation a step on from the telephone tip line, Nasa is encouraging the public to contribute evidence to the site, run by the Johnson Space Centre in Houston.
Witnesses to Saturday's space shuttle disaster can submit their video or photographs in either Real Media or jpeg formats. They are also asked to submit a text file including their name, email address and the circumstances in which the photos or video were taken.
The site provided the example: "I, John Doe, recorded this video in my front yard at 1111 My Street in Nacogdoches, Texas, at 7:55 a.m. on the morning of Saturday, Feb 1, 2003."
Security measures mean members of the public will not be able to view any of the images submitted for storage on Nasa servers, even their own.
