The internet radio show program is from 12-1.30pm PDT which I think equates to 4-5.30pm in Porto Alegre, Brazil and 8-9.30pm in London, UK.
Go to www.thespaceshow.com and click on LISTEN LIVE and you will find options for listening via internet radio. Interviews can also be listened to at a later date or downloaded in mp3 format.
The Space Show is more than 7 years old now and has conducted nearly 1,500 live radio interviews. The focus of the program is to further space commerce, space development, science, space tourism, and above all, realistic space education relating to all of these subjects and more.
(Interview will be in English)
