Feedback: What did you think of this show?: 

Alfred Zaehringer returned as the guest for this Space Show program. Mr. Zaehringer focused on rocket economics during the program, explaining in detail why it is difficult and maybe impossible to substantially lower the cost of getting to LEO, the Moon, or anyplace in space using chemical rockets. In response to his earlier appearance on the program Jan. 4th of this year, Mr. Zaehringer was asked a series of follow up questions exploring possibilities for reducing launch costs to the next lower level, $1,000 per pound to LEO. We discussed new and lighter materials, rocket motor design and pump changes, fuel, sustained high flight rates, range fees, insurance costs, and more. Mr. Zaehringer remains convinced that the price is not going to be that low with chemical rockets and he very clearly states why, citing the realities of physics and the rocket equation which cannot be ignored. For those of you interested in this subject, in seeing commercial businesses open up in space, on the Moon, or on near-Earth objects, listen to what Al Zaehringer has to say. He believes that dealing with reality is much better than trying to ignore it. He welcomes your feedback and he can be contacted at azaehringer@wideopenwest.com or through drspace@thespaceshow.com.
