Japan Considering Moon Base, Shuttle Projects
ScentCone writes "A brief article at Newsday mentions a Monday report that JAXA, Japan's counterpart to NASA, is looking at robotic probes on the moon by 2015, and construction on a solar-powered manned research base starting there by 2025. The (very) big bump in the agency's budget will also get spent on tsunami warning technology and other terrestrial communications technology development."
Zubrin (Guy who wrote case for Mars), who is a bit of a nut, but knows a lot about rocket engines, has suggested that while a reusable system is a good idea, the shuttle is basically built backwards. What we need is a system that has a disposable top, TPS if applicable, etc. But, a reusable first stage booster assembly. The first stage won't be subjected to the same level of thermal stress as the last stage, and so needs much less in the way of protection to be made reusable.
In many cases, there may not even be a reason to bring the last stage back, such as satellite deployment, etc, and the last stage mission requirements will vary so widely that it may not make sense to reuse it even if it is free.
