The luxuries of the modern-day living owe a lot to the services provided from outer space or passing through space. As the benefits of space technology permeate into our everyday lives, many new entrants, especially those from the developing regions of the world are initiating, synergizing, and expanding their national space programmes. Although having a space programme offers plenty of strategic and socioeconomic benefits and opportunities, it requires a high initial cost with most of the gains reaped in the long term. Therefore, the continual growth and long-term sustenance of a space programme is important for any nascent space power. Notwithstanding, the financial and technological constraints form a major caveat which, if not taken care of right from the onset, may seriously jeopardize the growth and in extreme situations, even endanger the long-term viability of the entire space programme. Hence, for nascent space powers, the ambition to do “big things” must start in small steps, articulated through a well-defined national space policy that can steer a correct direction for times to come. This article points toward the need to build space policies for nascent space powers that can justify the long-term investment in civil, commercial, and military programme applications of space technology. It identifies economic and technological constraints as the primary factors constraining nascent space powers that in turn govern the development of space policy. The article also identifies several of the macro-level challenges that need focused attention from policy makers and space programme managers for ensuring the development and sustainability of a viable space programme.

现代生活的奢侈很大程度上归功于外层空间或穿越太空提供的服务。随着空间技术的好处渗透到我们的日常生活中，许多新进入者，特别是来自世界发展中地区的新进入者正在发起，加强和扩大其国家空间计划。尽管制定太空计划可提供大量的战略和社会经济利益与机遇，但它需要很高的初始成本，而从长远来看，大部分收益是可以得到的。因此，对于任何新生的太空大国来说，太空计划的持续增长和长期维持都是重要的。尽管如此，财务和技术限制仍然是一个主要警告，如果从一开始就不注意权利，可能会严重损害经济增长，在极端情况下，甚至危及整个太空计划的长期生存能力。因此，对于新生的太空大国来说，要做“大事情”的野心必须从小步骤开始，这要通过明确定义的国家太空政策来阐明，该政策可以为今后的正确方向指明方向。本文指出，有必要为新兴的太空大国制定太空政策，以证明对太空技术的民用，商业和军事计划应用进行长期投资是合理的。它确定了经济和技术上的制约因素是制约新生的航天力量的主要因素，而这些力量反过来又控制着航天政策的发展。本文还确定了一些宏观挑战，决策者和空间计划管理者需要集中注意力，以确保可行的空间计划的发展和可持续性。
