MarkWhittington writes: Testimony at a hearing before the House Science Committee's Subcommittee on Space suggested that NASA's Journey to Mars lacks a plan to achieve the first human landing on the Red Planet, almost six years after President Obama announced the goal on April 15, 2010. Moreover, two of the three witnesses argued that a more realistic near term goal for the space agency would be a return to the moon. The moon is not only a scientifically interesting and potentially commercially profitable place to go but access to lunar water, which can be refined into rocket fuel, would make the Journey to Mars easier and cheaper.
