Here's one that I missed last year ... the Arthur C. Clarke Foundation has information about several awards. The 2006 Arthur C. Clarke Awards, the Lifetime Achievement Award and the Innovator's Award, went to Walter Cronkite and Robert Bigelow, respectively. The Innovator's Award is for innovation that supports communications satellites and their benefits to society, while the Lifetime Achievement Award is for contributions to arts and science that will benefit society now and in the future. The awards have been given to other notables in past years.
In addition, communications satellite company SES AMERICOM has set up the SES AMERICOM Arthur C. Clarke Challenge, which is for college students that produce significant ideas that would help communications satellites. The maximum award is $50,000.
The Foundation also offers scholarships for engineering, space, and space safety studies.
