Buzz Aldrin on the Fear of Flying in Space

In response to the Challenger explosion, Buzz Aldrin gives a first-hand view of the feelings of astronauts regarding their fear of flying in space (you'll need to do a one-time registration to access the NYTimes online site - it's worth it). So, what should we do now, halt space exploration and reassess our needs, or redouble our efforts and push ahead? Dan Gillmor and John Baer have interesting and opposing viewpoints on this increasingly controversial subject.

In a related story, if you have any photos or video relating to the Challenger explosion you can (believe it or not) send it to NASA via the internet.

And HERE is a summary of an extensive Washington Monthly article which focuses on the shuttle's thermal tiles and their inherent problems - VERY interesting reading. It includes a link to the original article.
