The roll out of the designs for the next generation Scaled Composites / Virgin spacecraft is a good time to point all the activity going on this sector. Dale Amon has a nice link list of the serious private ventures aiming to attract commercial passengers and cargo. In spite of the hype blip, parts of the Scaled Composites program are apparently still on hold, pending a final resolution of the cause of the deadly explosion at their Mojave facility back in July, so it's good to see not only a growing list of ventures, but a wide variety of approaches.
