Laramie, WY – New York Times science reporter Kenneth Chang spoke to University of Wyoming students about the future of U.S. space exploration today (Tuesday). Chang discussed the changes that the NASA Authorization Act of 2010 could bring. President Obama signed the act Monday. The act seeks to develop the relationship between NASA and the commercial space industry. But Chang lamented the lack of a clear agenda for NASA. He says it's important that there be a national dialogue about what NASA's mission should be.
