The Mars Society announced today that SpaceX founder and CEO Elon Musk will present a plenary talk at the 6th International Mars Society Convention, which will be held at the Hilton Hotel in Eugene Oregon, August 14-17, 2003. The founder of the PayPal payment system, Elon Musk is widely regarded as one of the most successful of the internet entrepreneurs to emerge from the 1990s. A long time supporter of space exploration and development, in 2001 Musk started investigating how he could make a difference in this area. The result was the June 2002 founding of SpaceX, a company devoted to reducing the cost and increase the reliability of access to space by approximately an order of magnitude.
