A teacher was being sent into orbit. The intent was for us to see a historic event. Instead we got to see even bigger history being made as the Space Shuttle exploded 73 seconds after launch. The disintegration of the vehicle was blamed on <a href=\"http:\/\/science.ksc.nasa.gov\/shuttle\/missions\/51-l\/docs\/rogers-commission\/Chapter-4.txt\">failure of the o-rings<\/a> to contain the hot gases. It grounded the shuttle program.<\/p>\n<p>When I attended <a href=\"http:\/\/www.spacecamp.com\/\">Space Camp<\/a> over a year later, the program was still grounded. One of my hopes was to better understand the cause. The adults instead steered us towards the physics of space flight and mechanics. A black spot on the history seemed to be avoided.<\/p>\n<p>Years later, my eighth grade science fair project was to show how freezing o-rings, especially with water involved, distorted their shape. Some o-rings even cracked. It earned me a second place overall for the school. It also got me to the regional science fair where it did not fare so well.<\/p>\n<p><a title=\"The Saturn Group by Ezra S F, on Flickr\" href=\"http:\/\/www.flickr.com\/photos\/sneezypb\/138746038\/\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/farm1.static.flickr.com\/47\/138746038_f7715cb783.jpg?resize=500%2C402\" alt=\"The Saturn Group\" width=\"500\" height=\"402\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Twenty-five years ago today my teachers had us all gather in a classroom.
