I just found this board yesterday and I am so grateful that something like this is here. Even though a layman, I am an avid NASA enthusiast. There really is no way or place to ask questions on the NASA web site itself. Also, I am sure they are far too busy for "fans" like like me. I just want to thank all of the brilliant and educated people that must be on this board, for taking the time to be invloved here and for talking about and responding to questions from the general public.I can't wait to just read all of the posts in the various sections! lol Thanks again to everyone who reads this, just for being out here.Sincerely,Dave D.
