Guest: Robert (Bob) Zimmerman. Topics: Space X, commercial space, human spaceflight, government regulation, government space programs. Please note that you are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Bob began our discussion with a reference to the Space X announcement about Falcon 9 Heavy made by Elon Musk on Tuesday, April 5, 2011.

Guest: Open Lines with Dr. David Livingston. Topics: policy, Obama Space, commercial space, various space start-ups. This was a two hour plus OPEN LINES program with almost non stop listener telephone calls in addition to email and chat. We started our fist segment with a phone call from Bob Zimmerman. Bob did a 15 minute or so rant on Obama space, the April 15 space conference at the Cape and more so don't miss this energetic start for this program.

Dr. Sam Dinkin returned as the guest for this Space Show program. We began the interview with a brief update from Dr. Dinkin on his new blog, Decisive Win (www.decisivewin.com). Check it and comment on it. Dr. Dinkin continues to write for The Space Review but his posting on his own blog will now constitute his blogging rather than his previous contributions to Transterrestrial Musings. The conversation then moved on for updates about SpaceShot, Sam's new start-up skill game to allow people the opportunity to earn a trip to suborbital space.
