PAULA ZAHN, CNN ANCHOR: It's that time now, almost 48 hours after the Columbia disaster, that friends and relatives of the Columbia seven astronauts are reflecting on their great achievements and their great passion for space. One crew member, Laurel Clark, was married and the mother of one child. And her brother spoke with us about his sister and talked about how he learned about the disaster.</s>DAN SALTON, LAUREL CLARK'S BROTHER: I had no idea that -- I had not watched the landing. I did not realize that when they lost communication that that wasn't normal. When it went on for a long time I just thought that they were in some kind of blackout zone. And it took me a good 10 minutes to finally realize what had happened. And it was a shock. Laurel was a very intense person who has, would set goals and would go for them, and I think that that's a great role model for kids today, to know that the goal oriented stuff they talk about, that they, that the counselors at school tell you about, it works. It gets you places. It can, you can do great things for humanity if you just set some small goals and always go for the next thing and set your sights higher. If when you reach that goal, then go for the next thing, and that's what she did. And we're all very proud for what she was able to do. And we certainly all hope that NASA keeps going and continues on with this research. I think it's very important for humanity to keep this going.</s>ZAHN: Wow. The memorial for Laurel Clark was held last night in her hometown of Racine, Wisconsin.
