I just woke up and rolled out of bed and learned that Columbia had exploded upon reentry. This is a very sad and mournful day. All my thoughts and prayers go out to them and their families. It's times like these that we see what is important in life. I hope that all of you are ok and keep the crew and their families in your prayers. I am going to go hug my parents and call my loved ones. This is a perfect example of never taking anything for granted, everytime you see a loved one, tell them how much you love them because you never know when it will be the last. God Bless.
