Fortunately, by sponsoring long-term, targeted initiatives, governments can stimulate more predictable demand. The Apollo program gave innovators clearly defined goals and a roadmap for getting there: first put animals in orbit, then put people there, then send probes to the moon, then send people there.
幸运的是，政府可以通过赞助有针对性的长期计划刺激更容易预测的需求。阿波罗计划为创新者明确制定了目标和实现步骤：先将动物送入轨道，之后是人，之后是向月球发射探测器，最后将人送上月球。
