Taxi...Take Me to The Moon
In the words of the late, great gonzo journalist, Hunter S. Thompson, “When the going gets weird, the weird turn pro.” That’s comforting to know because the future of America’s space exploration program has suddenly gotten weird, and the last thing you need when that happens is amateurs calling the shots. It all...
