Monday’s CSExtra offers new commentary on the future of U.S. human space exploration as well as new findings in space science.
1. From the Houston Chronicle: In an op-ed Christopher Kraft, the former director of NASA’s Johnson Space Center, and co-writer Scott Spencer, propose a new architecture for human deep space exploration. After underscoring the contributions to economic development of a goal driven exploration strategy, they propose a re-usable Planetary Transport Vehicle, which operates from the International Space Station. The PTV would be launched aboard the space shuttle, which continues to operate as a heavy lifter. The authors suggest astronauts return to the moon by 2019, aim for an asteroid by 2025, establish a lunar base by 2026 and reach Mars by 2035.
