Space 4.0 - New Nations, New Actors and the Evolving Space Ecosystem

About this Research Topic

Background

The field of space governance and technology is undergoing a profound transformation, driven by the shift from a nation-centric landscape to an increasingly democratized and dynamic space ecosystem. While international space law (ISL) has long defined the parameters of permissible activity in outer space, its foundational treaties mostly mirror the interests and power structures of the early spacefaring states. Recent technological advances and falling barriers to entry are reshaping the operational reality. Lower costs and the broad dissemination of know-how now enable emerging space nations and private enterprises to participate meaningfully in space activities, challenging the legacy status quo. As access to space becomes more democratized, significant questions arise about the adequacy of current regulatory frameworks, the readiness of new actors, and the evolving balance of power.

Recent studies signal a diversifying pool of participants in space, with innovative ventures in domains such as asteroid mining, debris management, small satellite deployment, and commercial launch services. These actors are not just replicating established models but are spearheading novel approaches potentially disruptive to traditional modes of operation. However, many of the legal and policy frameworks in place do not adequately anticipate the risks and opportunities posed by newcomers in the field. There are persistent gaps in regulatory harmonization and coordination, raising concerns over the long-term sustainability of the space environment, fair access, and the equitable sharing of benefits derived from space activities.

This Research Topic aims to scrutinize the novel solutions, strategies, and policies that emerging space-faring nations and private companies are pursuing to carve out a place for themselves in the expanding Space 4.0 ecosystem. The focus will be on understanding how these actors leverage technological innovation, policy development, and collaborative frameworks to build capacity and competitive advantages. It seeks to assess how these new participants might change the dynamics of global space governance, foster innovation, or disrupt established practices—either by addressing previously overlooked challenges or by pioneering specialized niche sectors in space.

To gather further insights in the evolution and limitations of this changing space ecosystem, we welcome articles addressing, but not limited to, the following themes:
• Innovative legislative and policy approaches for new actors in space
• Technological strategies and their implications for participation and competition
• Case studies on emerging space nations and private sector successes and challenges
• The impact of new actors on established stakeholders and on international law
• Issues related to sustainability, environmental risk, and space debris management
• Collaborative mechanisms and partnerships among old and new actors
• Analysis of emerging markets and niche services in the new space economy

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?
