    Japanese treefrogs (Hyla japonica), were sent to the space station MIR. Their behavior were observed under microgravity. After 8 days on orbit, all of the 6 treefrogs were recovered on ground. Readaptation of frogs to normal gravity, and biological effects of space flight were investigated.

    The paper briefly overviews the current activities on the microgravity missions . First, Spacelab missions will be introduced and secondly, those to be reported are being planned or carried out in National Space Development Agency of Japan (NASDA) under the name of Space Environment Utilization Promotion Project. Included in the project are utilization theme elaboration, utilization planning, generic experiment equipment evaluation, generic technology development, aircraft experiment and sounding rocket experiment. The progress status is to be reported and implication toward the future will be discussed.

  • The Coming Space Industry Revolution and Its Potential Global Impact

    To date the space age has not fulfilled the vision of the early space engineers and science fiction writers - who described a future in which large numbers of people work and live in space, both near earth and elsewhere in the solar system. More than thirty years after the first satellite launch, barely two hundred people have visited space at a cost of around $100 million per person. It is even argued that space exploration will forever performed mainly by automated vehicles. However, the development of fully re-usable launch vehicle over the next twenty years will greatly reduce the cost and danger of launches, and will greatly widen public access to space. On some scenarios as many as one million people could visit space on a commercial basis within twenty-five years. The economic implications of such a development are very significant both for the space industry and for the global economy.
